Important safety infomation: for your own safety, always use parts and accessories which have been approved by BMW.
Parts approved by BMW have been tested for safety, function and suitability for use on BMW vehicles. BMW accepts product liability for parts it has approved.
BMW is unable to accept any form of liability for parts, accessories or other products which it has not approved.
BMW clearly cannot assess every product of outside origin in order to ensure that it represents no risk of injury to the user if installed or operated with a BMW automobile. Nor can approval by an official technical inspection authority for the issue of a general operating permit by a government body provide absolute assurance that a product is entirely suitable, since the tests performed by such bodies tend to be of a more general nature only.

Original BMW Parts and Accessoires and other products approved by BMW are available from BMW Service, which will gladly provide competent advice on all related matters.
The functional efficiency and road safety of your BMW, and its resale value, may be adversely affected if changes not in accordance with its general operating permit or the manufacturer's specification are made to its equipment.
All dimensions, weights and performance data stated in this Owner's
Handbook are in accordance with the relevant German Industrial Standards
(DIN) and the tolerances laid down for them. National-market versions may differ from those described here.
Fuel consumption figures are as determined at the time of closing for press.
The high safety and quality standards of BMW vehicles are upheld by ongoing development in the design, equipment and accessories areas. This may give rise to discrepancies between the contents of this Owner's Handbook and your own vehicle. Nor can errors and omissions be entirely ruled out.
You are therefore asked to appreciate that no legal claims can be entertained in respect of the data, illustrations or descriptions quoted here.

Starting the engine
d d d d
Apply the handbrake.
The manual-shift gear lever should be in neutral; the automatic transmission selector lever should be in P or N.
At very low outside temperatures, keep the clutch pedal pressed down.
Start the engine without depressing the accelerator pedal.
b
Allow the starter motor to run for a reasonable time, but not for more than about 20 seconds. As soon as the engine fires, release the ignition key.
Do not allow the engine to warm up at a standstill, but drive off as soon as possible, using moderate engine speeds. c
If the engine does not start first time, for instance if it is very cold or very hot: d
Depress the accelerator pedal halfway while starting the engine.
Cold starts at very low temperatures
(under app. -15 6 ) at high altitudes
(above 1000 m): d d
Always run the starter motor for a fairly long period (about
10 seconds) the first time it is operated.
Depress the accelerator pedal halfway while starting the engine.
BMW 840Ci, 850CSi
If the car is to be used for lengthy periods at high altitudes and at extremely low temperatures, have the engine oil changed to 5W-X grade
(see Page 97). Please contact BMW
Service.
a
Never run the engine in an enclosed space. The exhaust gas contains carbon monoxide, which is colourless and odourless, but highly toxic. Inhaling exhaust gas constitutes a severe health risk and can lead to loss of consciousness with fatal consequences.
Never leave the car unattended with the engine running, as it then represents a serious potential hazard.
c
Stopping the engine
Turn the ignition key back to 1 or 0.
a
Never take the ignition key out when the car is still in motion or the steering lock will engage.
Whenever the driver leaves the car, he or she should remove the ignition key and lock the steering.
Manual-gearbox cars: when parking the car on a slope, apply the handbrake, as merely selecting 1st gear or reverse may not be sufficient to prevent the car from rolling away.
Automatic-transmission cars: select position P.

Running-in
Please comply with the following instructions, which are intended to ensure that your car achieves its optimum operating life and economy.
Engine and final drive
BMW 840Ci, 850Ci
Up to a distance reading of
2000 km (app. 1300 miles):
Drive the car at varying engine and road speeds, but do not exceed an engine speed of 4500/min or a road speed of 170 km/h (106 mile/h).
Avoid full throttle and do not use the automatic transmission kick-down.
After 2000 km (app. 1250 miles) have been covered, engine and road speeds can be gradually increased.
If the engine or final drive is exchanged later in the car's life, repeat the running-in procedure.
BMW 850CSi
Up to a distance reading of
2000 km (app. 1300 miles):
Do not exceed a max. engine speed of
5500/min.
Max. road speed 160 km/h (100 mile/h).
Do not use the full throttle position of the accelerator.
Up to a speedometer reading of
5000 km (app. 3100 miles):
Max. continuous road speed
200 km/h (124 mile/h).
Use top speeds for short periods only.
If the engine or final drive is exchanged later in the car's life, repeat the running-in procedure.
Tyres
New tyres do not achieve their full road grip immediately, for production reasons. You should therefore drive in a restrained manner for the first
300 km (app. 200 miles).
Brakes
Brake pads and discs do not achieve a favourable wear and contact pattern until the car has covered about
500 km (300 miles).
a
The brake lights do not come on when the handbrake is applied.

Refuelling Fuel grade
d d
To open the fuel filler flap, press the front end in so that the flap can be lifted.
b
When refuelling, insert the pump nozzle fully into the filler pipe. If the filler nozzle is raised during refuelling the supply of fuel will be cut off prematurely and on filler nozzles with fuel vapour recovery, the recirculating function will be less effective.
c
To release the fuel filler flap if the central
locking system fails, see Page 114.
a
Comply with the relevant safety regulations when handling fuel.
c
Spark-ignition engine with catalytic converter
BMW 840Ci, 850Ci
The engine should be run exclusively on unleaded fuel. Since the engines have a knock control function, they can run on different grades of fuel.
Minimum fuel grade: regular grade, unleaded (91 (RON).
The rated performance and fuel consumption values are achieved with: super (premium) grade unleaded fuel
(octane number 95, Research Method).
This fuel is also referred to as
DIN EN 228 or Euro-Super.
For higher performance and lower fuel consumption, it is also possible to use
Super Plus/premium plus fuel (octane number 98, Research Method).
BMW 850CSi
Minimum fuel grade: Super (premium), unleaded (95 octane, Research
Method).
The rated performance and fuel consumption values are achieved with:
Super Plus unleaded (98 octane,
Research Method).
a
Never use fuel containing lead if the car is equipped with a catalytic converter, or else the lambda probe and the converter will be damaged beyond repair.
c
Spark-ignition engines without catalytic converter
(Note: a catalytic converter can be retrofitted.)
The engine is designed to run on both unleaded and leaded fuel. Since the engines have a knock control system, they can run on different grades of fuel.
Minimum fuel grade:
Regular-grade unleaded or leaded fuel
(octane number 91, Research Method).
The rated performance and fuel consumption values are achieved with:
Premium-grade unleaded fuel (octane number 95, Research Method).
This fuel is also referred to as DIN EN 228 or Euro-Super.
For higher performance and lower fuel consumption, it is also possible to use
Super Plus, 98 octane (RON) unleaded or Super (premium), 98 octane (RON) containing lead.
Super (premium) fuel is also referred to as DIN 51 600.

Tyre pressures
Check regularly for your personal safety:
a
Incorrect tyre pressures can render the car unstable and lead to tyre damage or even cause an accident.
c
Tyre pressures in bar – gauge pressure
– (psi) with tyres cold (cold = ambient temperature).
These tyre pressures apply to makes of tyre approved by BMW and known to the BMW Service Organization.
If other makes of tyre are fitted to the car, higher tyre pressures may be needed.
The information relevant to your car is shown on a label attached to the driver's door post.
When towing a trailer, always use the values for the higher load.

Electronic Immobiliser
The electronic immobiliser reduces the likelihood of your BMW being stolen. It prevents the engine from being started except with the car's correct keys.
In addition to the mechanical matching of lock and keys, this is achieved by a special electronic component integrated into the key.
The vehicle's electronics exchange constantly updated signals, which are individualised for every vehicle, between the ignition switch and the electronic components in the key. The ignition, fuel supply and starter motor cannot operate until the key has been identified as valid.
b
The electronic components in the key could become damaged if treated violently. This could prevent you from starting the engine.
c
Obtaining a new key:
Spare keys are only available from
BMW Service, which is obliged to check that you are entitled to order them.
BMW Service can also invalidate individual keys (e.g. if they are lost), or reinstate them. The engine cannot be started with an invalidated key.
Keys
1 Master key with transmitter for remote control
2 Spare key to keep in a safe place, e.g. in a purse or wallet. This is a master key, but is not intended for regular use
3 Key for doors and ignition.
This key does not operate the luggage compartment or glove box lock. It is useful at a hotel, for example.
The passenger's door has no outside lock, as an additional precaution against theft. The safety button on the passenger's door does not operate the central locking system.
Online Edition for Part-No. 01 41 9 790 191 - © 12/98 BMW AG
Doors
Central locking from the outside
When the doors, luggage compartment and fuel filler flap are closed they can be locked and unlocked with a key at the door lock.
At the same time, the deadlock is operated. It prevents the doors from being unlocked either at the safety lock buttons or door handles.
a
Do not lock the car either with the key or the remote control if anyone is to remain in it, since it cannot then be unlocked from the inside.
c
If your car is equipped with an alarm system, it is also activated or de-activated with the key at the door lock.
For further details of the alarm sys-
Convenience circuit
The electric windows and the sliding/ tilt roof can also be operated via the door lock.
To open: when the door is closed, turn the key in the door lock to the release position and hold it there.
To fasten: when the door is closed, turn the key to the locking position and hold it there.
Release the key to halt the movement.
Emergency operation
(in the event of an electrical malfunction)
When the key is turned to the limit of movement in the door lock, the driver's door can be unlocked or locked.
Operating the central locking system from the inside

Central locking system pushbutton
This pushbutton also operates the central locking system when the driver's door is closed.
Automatic window lowering
The door windows are lowered slightly as the doors are opened, and run back up to the fully closed position as soon as the doors are closed. This makes it easier to open the doors, avoids damage to the rubber door seals and ensures that the glass is correctly located in the rubber door seal when the door is closed.
Driver's door lock heating
Raise the driver's door handle: the heating is switched on. The heating time is regulated automatically to reduce electric power consumption.

3 Turn the ignition key briefly (for not more than 5 seconds) to position
1, then back to position 0.
4 Press button 1 on the remote control (see illustration) and hold it down. Press button 2 briefly three times in succession within
10 seconds, while button 1 is held down.
5 Release button 1. The LED will flash slowly for max. 10 seconds.
6 The central locking system indicates that initialisation has been performed successfully by closing and releasing the locks in rapid succession.
If the LED does not flash and the central locking system does not operate, the initialising procedure must be repeated.
If you use additional remote-control transmitters for the same car, each of them (up to four) must be initialised within a further 30 seconds (repeat steps 4 to 6), otherwise they will be de-activated.
In the event of faults, contact BMW
Service, which can also supply replacement transmitters.

Alarm system
The alarm system reacts if: d d d a door, the engine compartment or the luggage compartment is opened.
the car's attitude changes, for instance if it is jacked up to remove a wheel or if it is towed away.
the power supply from the battery is interrupted.
It has three ways of indicating that the car has been tampered with: d d d by sounding an alarm for 30 seconds by switching on the hazard warning flashers for five minutes
*
.
by switching the low-beam headlights on and off in the same rhythm as the hazard warning flashers
*
.
On some national-market versions, the alarm system can only be operated from the remote control.
If such cars are unlocked manually with the master key, the alarm will be triggered off.
Pressing button 1 (unlocking) or starting the engine will switch the alarm off.
If you have any queries, your BMW
Service station will be glad to advise you.
Activating and de-activating
Activating and de-activating take place when the door key is turned or the remote control operated.
Activation is confirmed by the hazard warning flashers lighting up unce only.
Alarm system telltale
d d d
If the LED on the centre console flashes repeatedly: the system is activated.
If the LED flashes during the activating routine: not all doors, engine or luggage compartment or glove box are correctly closed, or a side window is open by more than a small amount (app. 10mm). But even if the item concerned is not closed correctly, the remaining items are protected and the LED will flash continuously after 10 seconds.
If the LED goes out when the system is de-activated: no attempt was made to enter the car during your absence.

Alarm system
d
If the LED flashes for 10 seconds when the system is de-activated: an attempt was made to tamper with the car.
If an alarm is triggered off, the LED flashes for 5 minutes and then reverts to the regular operating mode.
When the system is activated, there is no access to the luggage compartment. If the LED flashes fairly rapidly
(10-second intervals), this indicates that the luggage compartment lid was closed but not locked (key turned to right and removed).
To prevent an unwanted alarm signal being set off by the tilt detector, for example when the car is carried on a train or parked in elevating garages, this part of the system can be put out of action temporarily:
Immediately after activating the alarm system, repeat the activating procedure (in other words, turn the key to the locking position or press the remote control button a second time).
The LED lights up briefly and then flashes continuously. The tilt alarm sensor is then out of action until the entire system has been de-activated.
Emergency de-activating*
If normal de-activation is not possible, adopt the following procedure:
1 Open the door with a key. After the door has been opened, the alarm will sound for 30 seconds.
2 Turn the ignition key to position 1 so that the central locking system can release the remaining doors.
The system is now de-activated, but should be examined by BMW Service.

To relieve the load on the discs of the spine, sit well back in the seat with your back resting firmly against the seat back.
The ideal position is when the head is a straight-line extension of the spinal column.
On a long journey, the seat back can be inclined slightly more, to reduce muscular strain. You should still be able to reach the highest point on the steering wheel with the arms slightly bent.
c a
Do not reposition the driver's seat while the car is in motion. A sudden seat movement could cause you to lose control of the car and result in an accident.
During a journey, neither the driver's nor the front passenger's seat back should be reclined to an excessive angle. Otherwise there is a risk in the event of an accident that the seat occupant could "submarine" under the seat belt, which would then fail to exert its full protective action (see also safety instructions concerning "Seat belts").
Do not push the front seats rearwards if the car is standing on a slope (e.g. a garage entrance ramp or similar), or the automatic seat belt height adjusters could become disconnected.

Seat belts
For your own safety, please note:
Make sure that other occupants of the car also wear their seat belts.
Seat belts should not be twisted and must run firmly across the pelvis and shoulder. They should not pass over hard or fragile objects in your pockets.
The seat belt must not pass across the neck, become trapped at any point or chafe against any sharp edges.
The belt should be as close to the body as possible; therefore avoid wearing thick and heavy clothing.
Take up slack regularly by pulling up the belt at the shoulder.
a
For the following reasons, it is essential for the belt not to be worn slack:
In the event of a head-on collision, the lap belt could otherwise slide over the hips and injure the lower part of the body. Furthermore, excessive belt slack delays the restraining action.
Pregnant women are also advised to wear the seat belt at all times, making sure that the lap belt is low down over the hips and does not press against the abdomen.
Never restrain more than one person with each seat belt.
Babies or small children must not travel in the car on the lap of another occupant.
c
Child restraint systems*
Children up to the age of 12 who are below 150 cm (approx. 5 feet) in height must be protected by a suitable, approved child restraint system.
Babies up to 18 months can travel on the rear seat in a suitable cot or shell facing rearwards and retained by the standard seat belts.
BMW Service can supply suitable child restraint systems for the various age groups. a
Child restraint systems are not to be attached to the front passenger seat.
c
To permit a child's restraint system to be retained securely with the seat belt, your BMW is equipped with a lockable automatic seat belt reel.
Pull the belt out fully. Allow it to retract until the child restraint system is held securely.
After releasing the belt and allowing it to retract fully, the automatic reel will again operate normally.
In no circumstances are seat-belt or child restraint systems to be modified.
The seat belt reel will lock: d d if pulled out rapidly, during sudden braking or accelerating, d d when the car is cornered sharply, if the car is tilted at a considerable angle.
a
Drivers should ensure that their passengers also comply with the relevant requirements and instructions concerning seat belts.
c
For care of belts, see Page 141.

Airbags
d d
Driver's airbag
Passenger's airbag
The airbag restraint systems protect the driver/front passenger in a severe head-on collision. The inflated airbag restrains forward movement of the seat's occupant and protects his or her head and upper body against injury.
The picture shows the area within which the airbag restraint system is triggered off.
In less severe accidents and if the car rolls over, is sideswiped or struck from the rear, protection is provided by the seat belt alone.
a
The airbag is an additional safety device. It must not be regarded as an alternative to wearing the seat belt.

Service without delay.
b
The airbag telltale light also comes on if the belt catch tensioner is triggered off.
c
What happens when the system is triggered off?
The airbags, which are concealed under the flaps in the steering wheel or in the fascia, are inflated rapidly and burst out of the preformed aperture in the padded covers.
The entire process takes place with great force, within only a twentieth of a second.
In view of the system's very brief response time, the noise of propellant ignition, inflation and subsequent deflation is lost in the general accident situation.
Propellant gas and small quantities of gaseous fumes are released when the airbag is triggered off. They do not represent a health hazard or imply that the car has caught fire.
The sudden increase in pressure inside the car when airbags are inflated may temporarily impair the occupants' hearing.
Online Edition for Part-No. 01 41 9 790 191 - © 12/98 BMW AG
Airbags Main light switch
a
Your seated position should be as far as convenient from the steering wheel or fascia.
Always hold the steering wheel by its rim. Failure to drive in this manner could result in hand or arm injuries if the airbag operates.
No objects should be held or allowed to rest between the airbag and the seat occupant's body.
Always wear your seat belt on every journey. The airbags are additional safety devices, and must not be regarded as an alternative to wearing the seat belt. Please note that in less severe accidents or if the car rolls over or the impact takes place at the side or the rear, protection is only provided by the seat belt.
Child restraint systems mounted on the front passenger's seat are not permitted on cars with a front-passenger airbag.
In certain countries it is in any case required by law that children under the age of 12 should only travel on the rear seats.
Even if all the appropriate precautions are taken, the risk of facial injuries when airbags are triggered off cannot be entirely ruled out in all accident situations.
c
Airbag safety instructions
The airbag restraint system's gas generator must not be removed from the car.
Any testing and assembly work on it may only be carried out by specially trained personnel. In the event of malfunctions of the airbag system, if the car is laid up out of use or if the airbag system was triggered off in an accident,
BMW Service must be entrusted with the necessary repair or removal work.
No modifications to individual components or to the wiring should be attempted. This includes the padded cover in the centre of the steering wheel and the cover on the instrument panel, which must never be covered with adhesive or any other material or modified in any way. The steering wheel itself must not be taken off.
In order to comply with valid safety regulations, the airbag generator must only be scrapped by BMW Service.
Any careless or unskilled interference with the system could lead to its failure or to accidental triggering off with the risk of injury.
b
The driver should inform your passengers about the airbag restraint system and ensure that they comply with the necessary precautions.

Automatic transmission with STEPTRONIC
You can drive the car as with a conventional automatic transmission
(including Adaptive Transmission
Control), but you can also shift between gears manually if preferred.
To select individual gears manually, move the selector lever to the left, away from position D, and into the M/
S gate. This initially activates the
Sport program of the automatic transmission. As soon as you push the selector lever briefly in direction "+" or
"–", the Steptronic shifts the transmission up or down a gear.
To return to the automatic mode, push the selector lever to the left, into position D.

For notes on operation in the M/S
gate, see Page 70, and for details of
the Adaptive program see Page 71.
Moving the selector lever
A lock prevents the lever from being moved to positions R and P accidentally; the lock is released by pressing the button on the front of the selector lever handle (arrow).
The engine can only be started in selector lever positions P or N.
Before selecting any drive position, apply the foot brake, since the car will always tend to creep with a gear selected, even at idle speed.
When a drive ratio (forward or reverse) is engaged, wait until the transmission is felt to engage before releasing the brake and accelerating.

a
Before leaving the car when the engine is running, move the selector lever to P or N and apply the handbrake.
If you select N accidentally at a fairly high engine speed, release the accelerator immediately. Wait for the engine speed to return to an idle, then engage the desired transmission position.
c
P – Parking
Engage this gear only when the car is standing still. The driven wheels are locked.
R – Reverse
Engage this gear only when the car is standing still.
N – Neutral
Select only if the journey is interrupted for a fairly long time. When the car is being driven, only select neutral if a skid occurs.
D – Drive (automatic selection of forward gears)
Use this position for all normal driving.
All forward gears are available and the
AGS is operational.
Kick-down
To obtain maximum acceleration, press the accelerator pedal down beyond the normal full-throttle position, at which a pressure point must be overcome.
M/S – Manual shift mode and
Sport program
When the lever is moved from D to M/
S, the Sport program is initially selected (S appears in the gear display).
In position S, the AGS uses only the gearshift program with the most pronounced sports characteristic. The transmission shifts up as far as 4th gear.
The Sport program is recommended if you wish to make the most of the car's performance regardless of your current driving style.
If you now push the selector lever briefly forwards in the "+" direction, the transmission shifts up; if it is pulled back in the "–" direction, it shifts down. The first time the lever is pushed in either direction, the transmission switches to the manual mode.
The gear display shows M1 ... M5.
Unacceptable up- or down-shifts are disregarded by the Steptronic, for instance no down-shift takes place if it would lead to the engine overspeeding. The selected gear is displayed briefly on the instrument panel. If gears are changed several times in rapid succession, the last (impermissible) gearshift is shown briefly in the transmission display, then the current gear displayed again.
a
Note that when driving in the manual shift mode, adequate acceleration may not be available – for example when overtaking – in 4th or 5th gear, and a manual down-shift should therefore be made or the kick-down used.
c
To select P, R and N from the M gate plane, the lever must first be moved back to D.
Steptronic "thinks along with you" in the following situations: d d
To avoid excessive engine speeds, it shifts up to the next-higher gear automatically just before the governed maximum engine speed is reached.
At low speeds, it shifts down automatically without any action on the driver's part.

The car may move away from a standstill in 2nd or 3rd gear if the situation demands, for instance in winter driving conditions.
Shift electronics
O
If the warning light comes on or the "TRANS FAIL-SAFE PROG" appears on the Check Control, there is a malfunction in the shift electronics or in the automatic transmission.
All selector lever positions can still be selected, but in any forward gear position, only 4th and 5th gears are actually available.
Avoid severe loads and take the car to the nearest BMW Service point.

Adaptive program (AGS)
In selector lever position D the Adaptive Transmission Control system automatically chooses the most suitable shift program from those at its disposal. The control system responds sensitively to the driver's wishes (e.g. relaxed or more dynamic driving style), to road influences (e.g. slippery surfaces or steep uphill gradients) and to the current driving situation (e.g. twisting road, descending steep hill).
Special functions
In selector lever position D the Adaptive Transmission Control system influences the shift points by means of various special functions.
This has the effect of suppressing certain shifts that would normally have occurred, and may cause others to take place in certain circumstances although the driver would not have expected them.
Selection of winter program
When driving on slippery surfaces
(snow and ice), a winter shift program is selected automatically. The car moves away from a standstill in 2nd gear and shifts up to higher gears as early as practicable. This makes progress over slippery surfaces easier and enhances the car's traction and dynamic stability.
The transmission moves out of the
Winter program when the AGS detects a higher-grip road surface or if
DSC is switched off.

Cruise control
Any desired road speed above approx. 40km/h can be memorised and maintained automatically.
The memorised speed value is lost when the engine is switched off.
1 Acceleration
Moving the lever briefly:
The car's actual speed is maintained and memorised. Each time the lever is moved briefly to this position again, road speed is increased by app. 1km/h.
Holding the lever in this position:
The car accelerates without the accelerator pedal being touched. When the switch is released, the speed then reached is maintained and memorised.
2 Deceleration
Holding the lever in this position:
The car decelerates by automatic restriction of the throttle, provided it was previously travelling at a controlled speed. When the switch is released, the speed then reached is maintained and memorised.
Moving the lever briefly:
Each time the lever is moved briefly, the road speed is reduced by app.
1km/h if it was previously travelling at a set speed.
3 Recall
Moving the lever briefly:
The speed last memorised is recalled and maintained once it has been reached again.
4 Off
Moving the lever briefly: the cruise control facility is switched off immediately.
The cruise control is also switched off automatically: d d d
If the car exceeds the selected speed by app. 16km/h (10 mile/h)
If the car's road speed falls more than 8km/h (5 mile/h) below the selected speed
If a high rate of deceleration occurs (above 1.5m/s l ), for example on a steep hill, when braking and declutching or if the automatic transmission selector lever is moved from D to N.
a
Do not use the cruise control on twisting roads, if traffic is heavy or in any other situation which makes it too difficult to maintain a constant speed, nor when the road could be slippery
(snow, rain or ice) or on a loose surface (stone chippings or sand). In such situations, the car's behaviour will not be sufficiently flexible to take road and traffic conditions into account.

Automatic Stability Control plus
Traction (ASC+T) - BMW 850 CSi
This system improves driving stability, particularly when accelerating and cornering.
The system is in operation whenever the engine has been started.
The telltale light in the instrument cluster goes out after the engine has been started.
To switch off the system:
Press the button; the telltale light will come on.
To switch the system on again:
Press the button again; the telltale light will go out.
If the telltale light flashes:
The system is active, that is to say it is compensating for fluctuations in traction caused by road conditions.
If the telltale light does not go out after the engine has been started or comes on during the journey: the system is defective, but the car itself is fully operational with the exception of the ASC+T stability control function. Take the car to BMW
Service to have the fault repaired.

ASC+T
Operating principle
High-precision sensors monitor wheel rotating speeds. If differences are detected, the system interprets them as a sign that wheelspin is about to set in, and reduces the power input from the engine accordingly. If necessary, the rear wheel brakes are also applied momentarily to suppress wheelspin.
Although the action of this system may seem to be restricting available engine power and therefore be difficult for the driver to accept, it should be remembered that as much traction as can be achieved, and therefore optimum acceleration, are always available for the prevailing road, driving and climatic conditions, without exceeding the limits of dynamic stability.
DSC
a
Even with ASC+T, the basic laws of physics continue to apply. If the maximum possible speed in any given situation is exceeded, traction and lateral wheel location may be lacking.
The driver alone is responsible for avoiding this situation. The additional safety potential offered by this stability and traction control system must never be understood as an invitation to take additional risks.
c
The system may react adversely if tyres of different makes and types are used on the same car. You should therefore try to ensure that all the car's tyres are identical in make, type and tread pattern.
By switching off ASC+T it is possible to revert to the conventional driveline
(without electronic control). It may be desirable, for instance, to switch off the system to ensure maximum potential traction d d

Dynamic Stability Control (DSC) is an extended form of Automatic Stability
Control plus Traction (ASC+T).
It improves dynamic stability, particularly where lateral forces are encountered (e. g. cornering) and when accelerating.
It identifies and counteracts unstable driving situations and prevents the driven wheels from spinning in poorgrip or otherwise unfavourable conditions (slippery surfaces, bends).

DSC
The system is in operation whenever the engine has been started.
The telltale light in the instrument cluster goes out after the engine has been started.
To switch off the system:
Press the button; the telltale light will come on.
To re-activate the system:
Press the button again; the telltale light will go out.
Telltale light
If the telltale light flashes:
The system is active, that is to say it is compensating for fluctuations in traction caused by road conditions.
If the telltale light does not go out after the engine has been started or comes on during the journey:
The system is defective, but the car can still be driven normally with DSC out of action. Take the car to BMW
Service to have the fault repaired.
Operating principle
Highly-sensitive sensors monitor wheel rotating speeds and the steering lock angle. If wheel speeds vary or differ from the calculated value at a given steering lock angle, the system registers the likelihood of wheelspin and reduces engine output accordingly; if necessary, either driven wheel can be braked momentarily to prevent it from spinning.
Although the action of this system may seem to be restricting available engine power and therefore be difficult for the driver to accept, it should be remembered that as much traction as can be achieved, and therefore optimum acceleration, are always available for the prevailing road, driving and climatic conditions, without exceeding the limits of dynamic stability.
When the system is functioning and the brakes are being applied, a certain amount of noise is generated.

Even with DSC, the basic laws of physics continue to apply. If the maximum possible speed in any given situation is exceeded, traction and lateral wheel location may be lacking.
The driver alone is responsible for avoiding this situation. The additional safety potential offered by this system must never be understood as an invitation to take additional risks.

Automatic air conditioning
When a button is pressed, the corresponding LED lights up if the system was switched on at airflow volume selector wheel (3).
Temperature selectors for left and right sides of car
The temperature control is switched on and off at the rotary knob on the driver's side:
Left-hand limit position: no heating effect, maximum cooling output, temperature control off.
As the control is turned to the right, away from the detent position: temperature control cuts in.
Right-hand limit position (detent): maximum heating output, temperature control off (also emergency position if a fault develops in the electronic temperature control system).
The scales are merely intended as a guide to the interior temperature. The selected setting is reached as quickly as possible and does not normally need to be adjusted subsequently.
Alter settings by only small amounts at a time, to avoid undesirable temperature fluctuations.
On/off switch and airflow volume selector
Position 0: system is switched off, air intake closed.
Turned to the right as far as first detent: system switched on, minimum airflow.
Turned farther to the right: airflow increases.
Right-hand limit position (detent): maximum airflow volume (also emergency position if a fault develops in the electronic blower control system)
Program buttons for air distribution to left and right sides of car
Automatic air distribution
With only a few exceptions, this program can be used in all normal driving conditions.
Depending on actual temperatures, the air inlets are opened and closed automatically.
To ensure freedom from fatigue, the system works according to the warm feet - cool heat principle.
However, the air emerging from the facia grilles can be varied separately in temperature; see next page.
To ensure that this program can operate effectively, some of the outlet grilles on the facia and the doors must be open and the airflow volume selector should be turned past the first detent.
Air distribution through all grilles and outlets – no automatic control
This program is recommended in warm weather, for instance, if extra ventilation or cooling of the footwell areas is needed.

b
If the windscreen mists over on the outside when atmospheric humidity is very high, press the AUTO button or the airflow button for the footwell outlets only. No cooled air will then be directed onto the windscreen.
c a
Press this button to increase the airflow out of the ventilation grilles if the windscreen and side windows mist over during a journey and it would be undesirable to press button
6 (maximum windscreen and side window demisting).
c
Airflow to the footwell outlets only
The demisting outlets are also slightly opened.
This program is recommended in cool weather, for example, when airflow from the grilles is not wanted, or to heat up the footwells rapidly.
b
In all programs, air emerges from the demisting outlets only at first after a cold engine has been started, until the heater matrix has reached app. 30 6 .
c
Pushbutton for maximum demisting and drying of windscreen and side windows
The windscreen and the side windows can be cleared and dried rapidly with this program. The previously selected program is not lost.
For maximum effect, the engine must be at regular operating temperature.
Pressing this button again (the LED goes out) automatically restores the system's previous settings.
The windows mist or fog over as a result of moisture and condensate caused severe differences in temperature or a high level of humidity. The only remedy is to dry the glass with plenty of warm air.
b
The first time this button is pressed after starting the engine, the rear window heating is also switched on.
c
Air conditioning
The air is cooled and dried when the air conditioning is switched on, then re-heated according to the chosen temperature.
Depending on weather conditions, the windscreen may fog over momentarily when the engine is started.
At outside temperatures below about
5 6 , switch the air conditioning off to prevent the windows from fogging.
The windows may mist over if the system is switched on and off too often.
If air humidity is very high, it is best to switch the air conditioning on in good time (before moisture condensate can reach the evaporator) and dry the air, so that the windows do not fog over. Take care not to direct cooled air on to the windscreen, as it could mist or freeze over on the outside.
At the maximum cooling setting, the system switches over automatically to recirculated-air operation and the defroster outlets are closed.
We recommend leaving the air conditioning system switched on permanently in the summer.

Automatic air conditioning
Important notes on air conditioning system
It is common for the windows to mist over temporarily after the engine has been started and with the air conditioning system on.
When the air conditioning system is running, moisture and condensate produced by the evaporator is discharged under the car and may leave visible trails on the ground.
If the air conditioning system develops any faults, for instance if no cool air is delivered even when the controls are set accordingly, switch it off and consult BMW Service without delay.
Recirculated air mode
This is recommended if the outside air is dusty or smells objectionable. The air already inside the car then passes through the system repeatedly.
Although the air conditioning is switched on automatically at the same time to improve the quality of the air
(and dry it), you should not drive too long with the system in the recirculated-air mode.
b
If the windows fog over when the recirculated-air mode is in use, switch to fresh-air operation and run the air conditioning by pressing button 7.
c
Pushbutton for Automatic Recirculated Air Control (AUC)
Three functions are obtained in succession by pressing this button repeatedly, and confirmed by
LEDs.
Fresh-air operation: LEDs off.
Normal operation with fresh air from outside the car.
AUC operation: left LED is on.
The system identifies peak pollutant loads in the outside air and prevents them from reaching the car's interior.
A sensor measures the level of pollutants in the outside air. If the values increase, the system switches over automatically to recirculated-air operation.
Recirculated-air operation: the right
LED comes on.
b
If the windows mist over on the inside when AUC or the recirculatedair mode are in use, switch to fresh-air operation (LEDs go out), start the air conditioning with pushbutton 7 and if necessary increase the airflow volume. Noises heard after the engine has been switched off are caused by the actuating motors returning the ventilation flaps to their rest positions.

Micro-filter
Fresh air is drawn in through a microfilter. This filters out up to 100 X of all pollen and up to 60 X of dust particles in the air.
Change the filter at the car's regular servicing intervals. If airflow is noticeably lower than usual, this may indicate that the filter should be renewed earlier.
Warm feet and a cool head: stratified interior air temperature for fatigue-free driving
The air emerging from the facia and door grilles can be varied in temperature (except when maximum cooling is required):
Knurled wheel 1 turn to right – warmer turn to left – cooler.
Press the button: When the telltale light is on, the heated rear window is operating at full heat output (rapid demisting).
When the telltale light goes out, the heated rear window has switched over automatically to a low rating in order to save power. It cuts out completely after about 20 minutes unless switched off previously.
If necessary, press the button again:
This will start a new rapid demisting cycle.
To switch off: If the telltale light is on, press the button.
Whenever the engine is restarted, the heated rear window has to be switched on again if still required.

Independent heater
If your car has an independent fuelburning heater, it is also equipped with independent ventilation control.
However, independent ventilation control can be installed an its own.
Both systems are operated by the on-
The independent heater's operating period can be preselected so that the car's interior is already warm when the journey is due to start. Snow and ice are also easier to remove from the windows.
The independent heater runs for 30 minutes. Since its current consumption is high, it should not be run twice in succession unless there has in the meantime been an opportunity to recharge the car's batteries by a period of driving reasonable speeds.
The independent heater can also be switched on and off directly.
The independent heater can be run at outside temperatures below 16 6 , but not while the car is being driven.
The heated air is supplied automatically to the car's defrosting and footwell outlets; the heater runs at maximum output in all cases.
In ignition key position 1 you can vary the interior temperature (at the temperature selectors) and the air distribution (by means of the pushbuttons).
After it has been switched off (LED off) the independent heater continues to run for a short period.
If the independent heater does not start after a maximum of two attempts, or switches itself off automatically, consult BMW Service.
b
Even during the warm season of the year the independent heater should be run briefly about once a month.
To do this if the temperature is above
16 6 : d d
Press the TEMP and TIMER buttons on the on-board computer at the same time: the INV (inverted) inscription will appear.
Switch the independent heater on directly and switch off again after about 5 minutes.
c a
Never operate the independent heater in an enclosed space. Always switch off the independent heater before refuelling the car.
c
Independent ventilation
This system supplies air to the interior and lowers its temperature by means of the automatic air conditioning fan.
The switch-on time can be preselected; the ventilation then runs for
30 minutes. It can also be switched on and off directly. Since its current consumption is high, it should not be run twice in succession unless there has in the meantime been an opportunity to recharge the car's batteries by a period of driving reasonable speeds.
Independent ventilation control is available at outside temperatures above 16 6 , but not when the car is being driven.
Air is driven to the grilles in the fascia and doors. These grilles must therefore be opened before the independent ventilation control is switched on or preselected.

Driving hints
a
Do not rest your foot on the brake pedal while the car is in motion.
Even slight continuous pressure on the brake pedal could cause overheating, brake pad wear or even brake system failure.
Aquaplaning:
Reduce speed when driving on wet or slushy roads, since a wedge of water could otherwise build up between the tyres and road. This situation, known as aquaplaning, means that the tyre can actually lose contact completely with the road surface, so that the car can neither be steered nor braked properly. You should therefore always reduce speed on a wet road.
Rear-window shelf:
Never place hard or heavy objects on the rear window shelf; they could be dislodged when the car is braked heavily and endanger the occupants.
Coat hooks:
When hanging clothing from the hooks, do not obstruct the driver's view. Do not hang heavy objects from them, to avoid the risk of personal injury if the car is braked suddenly.
c
Cars with catalytic converter
The catalytic converter reduces pollutant emissions in the exhaust.
Cars equipped in this way must always be run on unleaded fuel only.
Even a very small amount of lead will permanently damage the oxygen sensor and catalytic converter.
To ensure that the engine always operates correctly and reliably, and to avoid damaging it, the following instructions should complied with: d d d d
Do not run the fuel tank dry.
Switch off the engine at once if misfiring occurs.
Never tow-start the car unless the engine is cold, or else unburned fuel may reach the catalytic converter. It is always preferable to use jumper leads from another car or a separate battery to start the car.
Avoid any other situations in which unburned or only partially burned fuel could pass through the engine, for example: frequent operation of the starter for very short periods or repeated attempts to start if the engine does not fire. (However, switching off an engine which is running normally and restarting it again shortly d afterwards is perfectly acceptable.)
Running the engine with a spark plug lead detached.
Always have the specified maintenance work carried out at the stated intevals.
If unburned fuel reaches the catalytic converter as a result of misfiring or fuel-air mixture preparation malfunctions, overheating and damage may result.
a
High temperatures occur on all vehicles equipped with a catalytic converter. Make sure that no easily combustible material (for example hay, leaves, grass etc.) comes into contact with the hot exhaust system when the car is being driven, is idling or is parked. If this material were to ignite and cause a fire, very severe injuries or damage could result.
Do not remove the heat shields from the exhaust system, or apply underseal to them.

Car radio operation*
For adjustments to your car radio and correct operation of its controls, please refer to the accompanying operation manual.
The reception and reproduction quality of any mobile radio installation depends on the range of the transmitter you wish to pick up and the alignment of the aerial.
Interference from high-tension overhead wires, but also buildings and natural obstructions, may cause noise and signal deterioration which cannot be avoided even if the vehicle's own interference suppression systems are in good working order.
Climatic influences such as sun spots, fog, rain or falling snow also influence radio reception.
The MW, LW and SW wavebands can be heard a long way from the transmitter, because the signals spread out both as ground waves and through the air, reflected by the ionosphere.
VHF (FM) reception provides far higher listening quality than any of the
AM wave bands. However, a VHF transmitter's range is limited to about
100 kilometres, since the signals travel only by line of sight.
Car phones not recommended by
BMW or other mobile phones could cause radio interference. This takes the form of a low-pitched humming in the loudspeaker system.
Car phone*
Mobile communication systems (car telephones, two-way radio etc.) can cause interference if they are not approved for use in your car. Since
BMW cannot examine and test each product, it is unable to accept any responsibility for the installation of items it has not approved. Before purchasing any such equipment you are recommended to consult your BMW service station.
Furthermore, in order to safeguard your
BMW's operating reliability, do not operate any in-car telephones or other mobile radio equipment with an aerial inside the car or with an aerial which is not attached to the outside of the car.
Detach the car phone aerial before driving on to a car train.

Engine oil
Motor- checking oil level
Like fuel consumption, engine oil consumption depends on driving style and operating conditions.
The oil level should therefore be checked regularly, approximately every 1000km (approx. 600 miles), or sooner if the car has been driven hard. The car should stand on a flat, level surface.
Maximum measuring accuracy:
Before a cold engine is started.
If the engine is already at its normal operating temperature, wait a short time so that the oil can drain back in the sump (for instance while refuelling).
Push the dipstick fully into its tube.
Examine the oil level: it must be between the two dipstick marks.
Motor- adding engine oil
Do not add more oil until the level has fallen almost to the lower mark on the dipstick. However, the oil level must not fall below the minimum level mark.
The space between the two dipstick marks represents approx. 1 litre
(1.8 Imp. pints) of oil. Never add oil beyond the upper dipstick mark. Adding too much oil will harm the engine because it will be burned off more rapidly, thereby implying that consumption was too high.
BMW engines are designed not to need separate additives in the engine oil, and adding these substances could even be harmful. The same applies to the gearbox or automatic transmission, the final drive and the power steering.

Brake fluid
Fill to the upper MAX mark (level can be checked from the outside).
BMW Service points are familiar with the factory-approved brake fluids
(DOT 4).
a
Brake fluid is hygroscopic, that is to say it absorbs moisture gradually from the air. To ensure that the brake system remains fully operational, the brake fluid must be renewed every
2 years by BMW Service.
c
Please note the instruction on Page
a
Brake fluid is toxic and attacks the car's paintwork. Keep it in sealed original packs, out of reach of children. When disposing of brake fluid, comply with environmental protection laws.
Do not spill brake fluid; fill the reservoir only up to the MAX mark. If brake fluid comes into contact with hot parts of the engine, it can ignite and cause serious burns.

Coolant
Coolant level with engine cold (app.
20 6 ):
Unscrew the reservoir cap.
The coolant level is correct if the top end of the red float rod is level with the top edge of the filler pipe (see arrow in illustration, or drawing on tank).
The coolant consists of water to which a long-life antifreeze and corrosion inhibitor has been added. The 50:50 mixing ratio must be maintained all the year round to ensure protection against corrosion. No other additives are needed.
Renew the coolant every 3 years.
Adding coolant to system:
Open the cap on the equalizing tank only when the engine has cooled down. The pointer of the coolant thermometer must be in the blue zone, or else there is a risk of scalding.
d d
Turn the filler cap counter-clockwise slightly until the excess pressure has escaped, then remove it.
If the level is too low, add coolant slowly until the level is correct – do not overfill.
a
Never fill the cooling system when the engine is hot. To avoid the risk of possible subsequent damage, use only factory-approved long-life antifreezes and corrosion inhibitors containing no nitrites or amino compounds. BMW Service points are familiar with these products. Antifreezes and corrosion inhibitors are toxic. Store them only in the original packs, out of reach of children.
Long-life antifreeze and corrosion inhibitor contains the flammable component ethylene glycol. Take care not to spill long-life antifreeze and corrosion inhibitor on hot parts of the engine, otherwise it can ignite and cause serious burns.

The two batteries are located behind the side trim panels in the luggage compartment. There is a positive terminal connection in the engine compartment, to which a jump-start lead can be attached if necessary (see
The batteries are maintenance-free to
German DIN 43539/2 standard, that is to say their acid content normally lasts for the lifetime of the battery.
If the acid level drops too low, for instance if the car is used for lengthy periods in a hot climate, top up with distilled water (not acid).
Acid level: up to the MAX mark on the outside of the battery in each cell
(app. 5mm above the tops of the plates of the cells).
Keep the tops of the batteries clean and dry.

Batteries
Q Read the following instruction before undertaking any work on the batteries:
R
Always wear eye protection.
No particles containing acid or lead should be allowed to reach the eyes.
S
Battery acid is highly toxic.
Wear protective gloves and suitable glasses or goggles.
Do not tilt the battery, otherwise acid could leak out through the gas vents.
T
Keep children away from batteries.
U
Avoid fire, sparks, or naked flames close to the battery.
Do not smoke. Try to avoid sparks when using cables or from other elctrical equipment. Avoid shortcircuits. Never short-circuit the battery terminals. The powerful arc which results could cause severe injury.
V
When the batteries are charged, a highly explosive gas mixture is emitted and can detonate.
W If any splashes of acid reach the eyes, rinse them out immediately for some minutes with clean water. Consult a physician without delay. Neutralize acid spillage on the skin or clothes immediately with soap and rinse off with plenty of water. If acid has been swallowed, consult a physician immediately.
X
To protect the battery case from ultraviolet rays, keep batteries away from direct daylight. As batteries which have run flat could freeze, store in a place where there is no risk of frost damage.
Removing and installing

If the car's own battery is flat, the engine can be started by using two jumper cables from another vehicle's battery.
a
Touching electrically live components while car's engine is running can cause a potentially fatal accident.
c
Do not depart from the procedure described below, or else personal injury could result or one or both vehicles be damaged.
1 Check that the other vehicle has a
12 Volt battery of approximately the same capacity (65Amp/h). This should be printed on the battery.
2 Do not disconnect the flat battery from the car's electrical system.
3 The bodies of the two vehicles must not touch, or a short circuit could result.
4 First connect the positive terminal of the other car's battery with one of the jumper leads to the positive pole in the BMW's engine compartment (this has a protective cover marked + which can be removed by pulling the flap (BMW
850Ci, 850CSi) or by pulling the two flaps at the side (BMW 840Ci - see left picture, arrow 1).
Then connect up the batteries' negative terminals. First attach the jumper lead to the negative terminal of the other vehicle's battery or to the other car's engine or body earth and then to the engine or body earth (nut on spring strut dome, see picture, arrow 2) of your own car.
a
When connecting up jumper leads, including when assisting other vehicles, please work in the sequence stated above in order to prevent sparks occurring at the battery.
c
5 If the second vehicle's battery is not well charged, run that vehicle's engine. Start your own car's engine in the usual way and leave it running.
Before detaching the jumper leads from your BMW, switch on your car's lights, heated rear window and heater blower (at maximum speed) to ensure that the voltage reaching the consumers from the regulator is not too high.
Then disconnect the jumper leads in the opposite order (negative pole first, then positive pole).
Have the battery recharged (depending on the cause of the fault).

Changing a wheel
a
The car should ideally be positioned on a level, firm surface which affords a good grip if a wheel is to be changed. On a soft or slippery surface
(snow, ice, tiles or similar) the car or the jack could slip sideways.
The car jack should likewise rest on a firm surface.
Do not position wooden blocks etc. beneath the jack, as its maximum load capacity could otherwise be exceeded. Never lie under the car or start the engine when it is jacked up; a very severe or fatal injury could result.
Additional safety precautions in the event of a flat tyre:
Where possible, take the car off busy roads and away from moving traffic.
Allow the steering lock to engage in the straight-ahead position, apply the handbrake and select first or reverse gear or automatic transmission selector lever position P.
Switch on the hazard warning flashers
Request all occupants to leave the car and to wait in a safe place (e.g. behind roadside crash barriers).
If necessary, set up the warning triangle or a flashing warning light at a sufficient distance to the rear. Comply with national legislation in these respects.
c
Jack
In the luggage compartment, behind the left trim.
To avoid rattling noises later, note how the various tools are attached to the car and replace them in precisely the same positions afterwards.

2 Slacken the wheel studs by half a turn.
3 Press in and remove the jack attachment socket cover at the appropiate point of the car (arrow).
4 Insert the jack fully into the socket and position it so that the base is resting firmly on the road.
5 Raise the car's body with the jack until the wheel to be changed is clear of the road.
a
Use the jack only for wheel changing. Never attempt to lift another type of car or any other heavy object with it, as this could lead to accidents and personal injury.
Do not lie under a jacked-up car – a very severe or fatal injury could result.
c
6 Take out the wheel studs and remove the wheel.
7 Insert the centering pin from the car's toolkit into one of the threaded holes, with the plastic cap in position on it.
8 Offer up the new wheel, insert at least two of the studs at opposite points and take out the centering pin.
For light alloy wheels with turbine styling or with a directional turbinestyle cover, please note:
These wheels or covers are asymmetric, and therefore intended to rotate in one direction only. The spare wheel matches the wheels on the right of the car; the spare wheel for the BMW 850CSi does not have a cover.
The wheel illustrated is on the left of the car.
If a puncture has occurred, the BMW
850Ci's spare wheel can also be fitted on the left of the car, but a wheel which rotates in the intended direction should be fitted instead as soon as possible.

Winter operation
Changeable weather in the winter months not only calls for a suitably cautious style of driving but also for certain measures to be taken on the car, to ensure that it can be driven safely and without problems throughout the winter.
Coolant
Make sure that the required mixing ratio of 50 to 50 parts of water and long-life antifreeze and corrosion inhibitor is present in the system all the year round. It provides protection down to a temperature of app. -37 6 .
Renew the coolant every 3 years.
Locks
Do not use de-icer, as it has a degreasing effect and will impair the functioning of the locks.
Rubber parts
To prevent the seals from freezing together, treat rubber surfaces with a rubber care product or silicone spray.
b
Suitable care products are available from BMW Service.
c
Snow chains*
BMW snow chains
*
, if used, must only be fitted to both rear wheels (with summer or winter tyres), making sure that the manufacturer's safety instructions are observed. Do not exceed
50km/h (31 mile/h) with snow chains fitted. To enhance traction, it is best to switch off ASC+T/DSC if snow chains
Moving off
To move away in deep snow or to
"rock the car free" it is best to switch
Driving on slippery roads
Operate the accelerator pedal sensitively, avoid high engine speeds and shift up to the next higher gear early.
On uphill or downhill gradients, select the next lower gear in good time.
Maintain a generous distance from the vehicle in front as a safety precaution.
Brakes
Winter road conditions greatly reduce the amount of tyre grip that is available, so that the driver must expect braking distances to be considerably longer than usual in every situation.
ABS prevents the wheels from locking, so that the car remains stable and can always be steered. Should the
ABS fail and the road wheels lock, reduce pressure on the brake pedal immediately so that the wheels can still turn although they are being braked. Then increase pedal pressure again until the same situation occurs, and repeat this as often as necessary.
This cadence braking principle cuts braking distances and keeps the car steerable, so that you can try to drive round obstructions at reduced braking pressure.
a
Do not shift to a lower gear as a means of braking the car if the road surface is slippery, or the rear wheels may slide and control of the car may be lost. ABS and ASC+T/DSC cannot prevent this situation, as they do not influence this method of slowing down the car.

b
When applying the brakes hard on slippery roads or if the amount of surface grip varies widely, always declutch as well.
c
If the car skids
Take your foot off the accelerator and depress the clutch or move the automatic transmission selector lever to N.
Try to steer into the skid and bring the car under control in this way.
Parking
Select the 1st gear or reverse, or move the automatic transmission selector lever to P. If the car is parked on a slope, apply the handbrake as well. To prevent the handbrake linings from sticking to the drums as a result of frost or corrosion, dry the drums by applying the handbrake lightly as the car is coming to halt.
a
The brake lights do not come on when the handbrake is applied.
c
Towing a trailer
When a trailer is towed, the demands on both car and driver are more severe.
A trailer reduces manoeuvrability, the ability to climb hills, acceleration and braking capacity and makes the car handle and corner differently.
The trailer load limit and the permissible nose weight (towbar downthrust) are stated in the "Technical Data",
Page 149. The trailer load limit is also
recorded in the car's registration document. Consult BMW Service regarding increased trailer weights.
Trailer tow hitch*
The trailer tow hitch
*
with detachable ball head should be of BMWapproved pattern and, like the trailer turn indicator repeater (which is normally a legal requirement) should be expertly installed by BMW Service.
Keep the detachable ball rod greased to make fitting and removal easier.
Both the comfort and sport suspension settings of your BMW afford optimum safety, ride quality and consistency of handling. They are also perfectly suitable for towing a trailer at up to the standard specified weight, provided that towing is restricted to one vacation period per year or thereabouts,and the driving style is modified to allow for the more severe operating conditions.
If a trailer tow hitch is retrofitted, it is also a good idea to install the trailertowing suspension. This compensates for the weight of the tow hitch and also ensures optimum road behaviour when the trailer is not being towed. It is also essential if higher trailer weights are to be towed (possible with certain types of trailer).
BMW has not approved any other suspension systems offered by the automotive trade for trailer towing purposes.
b
If a trailer tow hitch is installed, the self-regenerating action of the rear bumper system may not be able to take effect.

Towing a trailer
The use of a stabilizing device can be recommended, particularly if the trailer is a heavy one. Information can be obtained from BMW Service.
Nose weight
This is the load exerted downwards by the trailer on the ball head of the tow hitch attached to the rear of the car (it can be determined with the aid of bathroom scales or similar).
In Germany a minimum nose weight of
25 kg (55 lb) is laid down by law.
If the trailer weighs more than 1600kg
(3527 lb), the nose weight must be at least 50kg (110 lb).
The nose weight limit should if possible be fully utilized but not exceeded.
The trailer's nose weight is added to the weight of the car, and must not lead to the car's gross weight limit or rear axle load limit being exceeded.
The car's payload is reduced by the nose weight if a trailer is being towed, and also by the weight of the trailer tow hitch.
Loading
When loading the trailer, make sure that the weight is kept as low as possible and stowed if possible close to the axle.
A low centre of trailer gravity makes the outfit much more stable and safe to drive.
Do not exceed neither the trailer's gross weight (axle load) or the specified trailer load limit for the car. The smaller value is the limit which should be adhered to.
Before acquiring a trailer it is desirable to obtain from the manufacturer a guaranteed statement of the effective trailer weight and the payload limit.
Electrical system
Higher electrical consumption can be expected if a trailer (caravan) is towed.
Run high-consumption items in particular for as short a period as possible in order to avoid draining the battery.
The trailer's rear lights, brake lights and rear fog light are protected by plug-in fuses in the trailer electrical module. This is behind the left luggage compartment trim. The fuse for the permanently positive line is in the luggage compartment, next to the left battery, in a separate fuse box.
a
Always check that the trailer's rear lights are working before starting a journey.
c
Outside mirrors
The standard outside mirrors may prove inadequate for trailer towing work: the law lays down that the car should be equipped with two outside mirrors with which the rear corners of the trailer can be seen. Mirrors of this kind, including versions with adjustable arms, can be obtained from
BMW Service.

Towing a trailer
Gradients
In the interests of safety and the avoidance of traffic obstructions, the maximum gradient (applicable at sea level) is limited to 12 X or, with a higher trailer load (if authorized), 8 X .
As altitude above sea level increases, engine power output tends to drop.
You should therefore take particular care when driving through the mountains, since the maximum gradient on which the outfit can be started may be lower than usual. Do not make full use of the car's and trailer's gross weight limits.
Downhill gradients
Special care must be taken when descending gradients: always shift down to the next-lower gear before reaching the gradient – if necessary, as low as 1st gear or selector lever position 2 – and drive down the gradient slowly.
125
Speed limit
The maximum speed limit is 80km/h
(app. 50 mile/h) in Germany. Trailer load limits have been chosen to ensure ample driving stability up to this speed. Although higher speeds may be permitted in other countries, you are recommended not to drive faster for safety reasons.
If the trailer begins to swing from side to side, the outfit can only be stabilized by braking immediately.
Tyre pressures
Check the car's and the trailer's tyre pressures most carefully. Comply with the trailer manufacturer's tyre pressure instructions.
Cover flap
Take hold of the cover flap for the trailer tow hitch at the top cutout, pull to the rear and down (if necessary, use a screwdriver to unclip it) and remove it from the lower guide.
For attaching and removing the ball head, please refer to the separate instructions.
To attach the cover flap, first locate the groove at the bottom in the guide and then press the flap into place at the top.

126
Roof rack*
A loaded roof rack alters the car's road behaviour and steering response quite considerably, by moving its centre of gravity.
When loading the roof rack, ensure that the specified roof load limit, the car's gross weight limit and the axle loads are not exceeded.
A special roof rack system is available as an accessory for your BMW. If it is used, please comply with the installation instructions supplied.
The roof load must be uniformly distributed and should not be too large in area. Heavy items of luggage should always be placed at the bottom.
Correct, secure loading of the roof rack will prevent items from shifting or falling off during the journey, and thus endangering following traffic.
Drive smoothly when there is a load on the roof: avoid violent acceleration, braking or cornering.
The roof load increases the car's surface area exposed to the wind, so that fuel consumption will be higher and the loads on the roof structure of the car more severe.
Driving on the right/left
When entering a country in which the traffic drives on the other side of the road:
1 Take off the painted upper section of the pop-up headlight: turn the toggle fastener through a quarter of a turn and lift the upper section slightly. Push the upper section forwards and take it off.
2 Take out the plug.
3 For driving on the left: move the lever to the left. For driving on the right: move the lever to the right.
a
When attaching the painted upper section of the pop-up headlights, make sure that it is correctly seated, particularly at the front mounting points, and that the toggle fastener is properly secured by rotating through a quarter of a turn.

Licensing for use abroad ABS
Cars are always supplied to conform with the registration laws of the country in which they are intended for use.
If the owner moves to another country, it is important to check beforehand that import regulations and vehicle licensing laws do not make it too difficult to import the car.
You can obtain infrmation in Germany by telephoning 089-382-0 and stating the model, vehicle identification number and date first registered.
In other countries, please consult
BMW Service or the importer.
The anti-lock brake system (ABS) prevents the wheels from locking and thus enhances active safety. Locked wheels are dangerous, because the front wheels cannot then be steered and the rear wheels may slide sideways and cause the car to spin or slide off the road.
With ABS in action, the car achieves the shortest possible braking distances for the prevailing conditions
(straight-line braking or cornering, on asphalt, ice, wet roads etc.).
ABS is capable of satisfying two fundamental requirements whenever the brakes are applied: d d
Assured driving stability on varying road surfaces (e.g. asphalt, concrete, mud, wet roads, snow and ice).
Assured steerability and manoeuvrability in these conditions.
127
However, certain important considerations must be borne in mind in connection with these requirements:
Even ABS is unable to eliminate the effects of natural physical laws. It cannot absolve the driver from the consequences of braking too late, maintaining insufficient space from vehicles ahead, exceeding the limits of adhesion when cornering at speed or encountering a poor stretch of road where aquaplaning occurs. Avoiding such situations remains the driver's responsibility.
Although ABS enhances active driving safety, this should not be regarded as an invitation to take correspondingly severe risks.

ABS
Driving with ABS
After the engine has been started, the yellow ABS warning light on the instrument panel goes out.
The ABS system itself becomes operational above a road speed of app.
8km/h (5 mile/h). If the car's speed drops below app. 3km/h (2 mile/h), the ABS ceases to take effect, so that in the very last phase of a brake application the wheels could theoretically tend to lock, but in practice this is not critical
The ABS regulation cycle takes place within fractions of a second. The brake pedal pulsates to warn the driver that the ABS is active and therefore that the car is reaching the adhesion limit.
In addition a chattering noise is heard
– caused by the pressure regulating action – to remind the driver that the tyres' grip on the road is decreasing
(slippery surfaces) and that the car's speed may therefore need to be reduced accordingly.
a
If the road surface consists of loose material on a firm underlayer, for instance stone chippings or powdery snow, the car's braking distance may sometimes actually be longer than if the wheels were to lock.
The same applies if snow chains are fitted. However, the advantages of greater stability and the ability to steer while braking are still available to the driver.
To ensure that the ABS system always remains fully operational it must never be modified in any way, and all work on the ABS should be entrusted only to skilled, authorized personnel.
c
ABS may not function at maximum efficiency if tyres of different sizes are fitted (e.g. winter tyres/spare wheel); in such cases, revert to the correct wheels and tyres as soon as possible.
Any malfunction is shown by the yellow ABS warning light on the instrument panel coming on. The brake system continues to work normally as on a vehicle without ABS, but should none the less be examined without delay by BMW Service. Additional faults to the brake system could otherwise occur without being readily apparent.

Active Rear Axle Kinematics (ARK)*
Unforeseen driving situations often call upon the driver to react swiftly by taking corrective steering action. The vehicle may be felt to respond in a surprising or unpredictable manner as a result. The ARK system modifies or prevents such reactions.
At a speed of app. 40km/h (app.
25 mile/h) or above, the ARK is activated with every movement of the steering wheel; it modifies the rear wheel lock angle and repositions the rear wheels ideally to suit the driving situation.
The optimum rear-wheel angle is calculated from the steering wheel's momentary lock angle and the vehicle's road speed; the wheel angles are then adjusted by the electrohydraulic control circuit. As a result of the vehicle's increased stability, it responds more predictably to steering wheel movements.
However, these improved driving characteristics cannot overcome the basic laws of physics to which a moving vehicle is subject. It remains the driver's responsibility not to initiate excessive steering-wheel movements or go beyond safe cornering speeds.
Each time the engine is started, the
ARK control unit runs through a selfcheck sequence. In the event of a system fault, which will be indicated by the telltale light in the instrument cluster and the display R/AXLE FAILSAFE
PROG in the MID, the lock angle of the rear wheels will no longer be adjusted. The wheels will normally remain in the straight-ahead position, with the result that the vehicle can be driven normally. In exceptional cases, the wheels could remain locked at an angle. If this occurs, the steering wheel will be slightly offset to compensate when the vehicle is travelling in a straight line. Here again, the vehicle can still be driven normally. Note, however, that in this situation the rear wheels will run slightly off-track and the vehicle will occupy marginally more road space across its width as a result.
129
Minor, temporary faults can be rectified by starting the engine again to initiate the system's self-check. If the telltale light does not go out even after the engine is restarted, contact BMW
Service to have the system repaired.

Disc brakes
Disc brakes offer maximum braking efficiency, responsive control of braking force and the ability to resist severe loads.
If the car is not driven very far, is parked out of use for lengthy periods or is mostly driven very gently, corrosion of the brake discs and contamination of the pads may unfortunately be encouraged, since the minimum pressures between pad and disc which are needed to obtain an automatic cleaning action are seldom reached.
When the brakes are applied, corroded discs tend to judder, and even lengthy brake applications usually fail to eliminate this effect entirely.
a
Use only brake pads approved by BMW, or else the car's operating permit will be invalidated.
c
Driving hints
In damp weather or heavy rain it is advisable to apply the brakes with light pedal pressure every few kilometres. When doing so, make sure that no other road-user is endangered.
This will generate sufficient heat to dry out the discs and pads.
It is a well-known fact that the best braking effect is obtained not withlocked wheels but with wheels that are still just rotating. ABS maintains this state of affairs automatically. If an
ABS malfunction occurs, the driver should adopt the cadence braking
principle if possible (see Page 122).
To avoid any risk of brake fade when descending long or steep hills, select the gear which calls for a minimum amount of braking (or shift the automatic transmission down to an equivalent speed stage).
Engine braking can be enhanced by shifting to a lower gear, if necessary as far as first gear or selector lever position 2.
If engine braking alone is insufficient, do not apply the brakes for too long with only slight or moderate force.
Instead, it is better to brake the car quite hard (providing that the road behind you is clear) so that your speed is reduced noticeably, and to repeat this process at brief intervals as necessary. The cooling-down phases between these brake applications should avoid overheating and maintain full braking efficiency.
a
Never hold the clutch pedal down, move the gearbox or automatic transmission into neutral or – an even more dangerous practice – switch off the engine while the car is in motion.
Engine braking is lost in neutral, and there is no brake servo effect when the engine is stopped. Make sure that the full travel of the brake, clutch and accelerator pedals is never obstructed by the floor carpet, loose mats or any other items.

Tyre pressures
Information for your safety
The factory-approved radial-ply
(braced tread) tyres have been chosen to match your car's performance and to ensure driving safety and the desired standard of ride comfort.
The condition of the tyres and maintenance of the specified tyre pressures not only influence tyre life but also road safety to a very considerable extent.
Incorrect tyre pressures are often a cause of tyre problems. They also have a considerable effect on the roadholding of your BMW.
a
Check tyre pressures regularly
(including the spare wheel) before starting a long journey and in any event at least twice a month. Failing this, incorrect tyre pressures could render the car unstable when driven or cause tyre damage which could result in an accident.
c
Tyre tread
Inspect tyres frequently for damage, the presence of foreign bodies, unusual wear and sufficient tread depth.
Tread depth should not be less than
3mm (app. 0.12 in), even if the minimum legal requirement is only 1.6mm
(app. 0.06 in). You are recommended to replace tyres when the tread depth is down to 3 mm, or else the risk of aquaplaning on even shallow water will be increased.
We recommend fitting new tyres when the treads are 3mm deep. If they remain in use, wear indicators in the base of the tread appear at a tread depth of 1.6mm as a warning that the legal wear limit (valid throughout
Europe since 01.01.1992) has been reached.
When parking the car or driving over loading ramps, workshop hoists etc., make sure that the side walls of the tyres are not damaged by violent contact with obstructions.
a
Never try to drive any further if a tyre goes flat. If air pressure is lost from a tyre, this seriously affects the car's handling and braking, and could cause the driver to lose control.
Avoid overloading the car, as this
131 could cause the tyres' load capacity limit to be exceeded. Overheating can also occur, and the tyre can suffer internal damage at a relatively rapid rate. This could lead to sudden pressure loss.
Unusual vibration while the car is being driven could indicate a tyre fault or some other defect on your car. The same applies to any other abnormal road behaviour, such as pulling severely to the right or left. In such cases, reduce speed immediately.
Proceed carefully to the nearest BMW
Service station or tyre dealer, or have the car towed there so that it can be checked or its tyres inspected.
All forms of tyre damage (which could in the worst case lead to sudden and total loss of pressure) represent a risk of serious or even fatal injury to the car's occupants and to all other road users.
c

132
New tyres
To maintain the car's good road behaviour, always fit tyres of the same make and tread pattern to all wheels. a
Do not use retreaded tyres on this car, as they could impair its road behaviour and safety. Their carcases may differ in internal construction or have aged sufficiently to cast doubt on their durability.
c
Interchanging wheels and tyres
Tread wear patterns vary between the front and rear wheels, according to the individual conditions in which the car is operated. In the interests of safety and the best possible vehicle behaviour, you are recommended not to adopt the practice of interchanging the wheels.
If you wish to interchange the wheels for reasons of operating cost, remember that the expense incurred in interchanging the wheels also has to be taken into account when assessing whether it is worth trying to extend the tyres' operating life in this way. BMW
Service can advise you.
If you do decide to interchange the wheels, please take the following precautions:
Interchange the wheels on the same side of the car only (though the spare wheel can be included if desired).
Remember that braking efficiency and tyre grip may be adversely affected.
If tyres are interchanged in this way, the process should take place at frequent intervals (max. 5000km/3000 miles).
Always check tyre pressures after fitting, and adjust as necessary.
Spare tyres more than 6 years old should be reserved for genuine emergencies, that is to say if the car's mobility cannot otherwise be maintained. New tyres should be fitted in their place as soon as possible, and they should no longer be brought into regular service when new tyres are fitted.
A tyre's date of manufacture is shown as part of the inscription on the tyre wall:
DOT ... 413 means for instance the
41st week of 1993

Choosing the correct tyres
Wheels and tyres
Use only BMW-approved tyres. In view of the car's maximum speed, certain makes and sizes are compulsory. Details can be obtained from
BMW Service. Comply in addition with any relevant national regulations.
The correct choice is made easier if the meaning of the tyre markings is understood. For radial-ply tyres, the following markings apply: e.g.
235/50 R 16 95 W
Nominal width in millimetres
Aspect ratio in X
Code letter for radial ply
Rim diameter in inches
Load capacity figure
(not on ZR tyres)
Speed code letter
(ahead of the R on ZR tyres)
The speed code letter indicates the maximum permissible speed at which the tyre is to be operated.
On summer tyres:
S = up to 180km/h (app. 112 mile/h)
T = up to 190km/h (app. 118 mile/h)
H = up to 210km/h (app. 130 mile/h)
V = up to 240km/h (app. 149 mile/h)
ZR = over 240km/h (app. 149 mile/h)
W = up to 270km/h (app. 167 mile/h)
On winter tyres:
Q M+S= up to 160km/h (app. 99 mile/h)
T M+S= up to 190km/h (app. 118 mile/h)
H M+S= up to 210km/h (app. 130 mile/h)
133
Marks on light alloy wheels:
9 g J x 18 AH 2
Rim width in inches
Rim shoulder contour code letter
Symbol for well-base rim
Rim diameter in inches

134
Winter tyres
If winter tyres – (M&S radial-ply) – are fitted, the same make and tread pattern should be used on all four wheels
(and preferably on the spare wheel as well) in the interests of good directional stability and steering response.
Fit only winter tyres approved by
BMW. BMW Service will gladly advise you on the correct winter tyres for the conditions in which your car has to operate.
Always note and comply with the maximum speed limit for your winter tyres.
In Germany: a suitable warning label according to § 36 StVZO has to be attached within the driver's field of view if the car's top speed is higher.
Tyre dealers and BMW Service points can supply these labels.
Below a tread depth of 4 mm (app.
0.16 in), winter tyres become noticeably less suitable for winter driving conditions and should therefore be replaced without undue delay for safety reasons.
Note the specified tyre pressures and have the wheels with tyres balanced each time a tyre or wheel is changed.
a
Always note and comply with the maximum speed limit for your winter tyres.
Lack of expert knowledge or incorrect handling of tyres can cause damage and lead to accidents.
All work on tyres should therefore be carried out only by experts. BMW
Service will gladly assist you.
c
Store wheels and tyres in a cool, dry and preferably dark place when not in use. Protect tyres against contamination from oil, grease and fuel.

Technical modifications
Any BMW Service point can provide you with information as to the practical value of an intended modification and whether it is legally permissible and approved by the manufacturer.
Enquiries should be accompanied by the vehicle identification number and, if relevant, the engine number.
Light-emitting diodes (LED)
Some of the controls, displays and other interior equipment of your car includes light-emitting diodes behind suitable covers as a light source.
These LEDs resemble conventional lasers and are classified by law as
Class 1 light-emitting diodes.
a
Do not remove the cover or expose the eyes directly to the unfiltered light source for several hours at a time, as this could cause irritation to the iris.

BMW Maintenance System
The BMW Maintenance System has been planned to ensure that the car always remains safe for the road and reliable, without any unnecessary expense for the customer. Regular and correct maintenance also helps to maintain the car's resale value.
Service Interval indicator
Advanced technologies have been adopted as a means of computing maintenance requirements, which are then shown on the Service Interval indicator. Whereas conventional maintenace schedules are based entirely on fixed distance intervals, the BMW maintenance system takes the car's operating conditions into account, bearing in mind that one kilometre is not the same as another:
100000km completed exclusively in the form of short journeys cannot be considered the same as 100000km made up of long main-road journeys only.
The BMW maintenance system based on actual operating conditions consists of an Oil Service and Inspections I and
II.
For further information on maintenance points and the scope of maintenance work, please refer to the car's Service
Booklet.
The principle of determining maintenance intervals according to load effectively covers all the operating conditions to which the car is likely to be exposed. However, if the car is very little used – that is to say if it covers distinctly fewer than 10000 kilometres (approx.
6,000 miles) a year – an annual engine oil change should be carried out, since the engine oil ages even if not subjected to mechanical loads.
Service Booklet
It may also be worthwhile having the body checked for stone-impact damage at the same time, in order to safeguard against corrosion.
Please make sure that the maintenance work is confirmed in the car's Service
Booklet. These entries are evidence that your car has been serviced regularly and correctly, and are also the basis of any warranty claims.
Online Edition for Part-No. 01 41 9 790 191 - © 12/98 BMW AG
Care of the car
Paintwork
The car's body is protected by multiple coats of paint against corrosion.
Note that body cavities have been protected in addition to cataphoretic dip coating by applying specially developed materials which have been subjected to prolonged testing.
The complete underside of the body is sprayed with a resilient PVC coating and then fully protected by a wax-based underseal.
Always remember that regular care of your car will go a long way towards maintaining not only its safe condition but also its resale value.
Environmental influences which differ from one region to another can affect your car's paintwork; the nature and frequency of the care you give the car should be governed by these factors.
Road dirt, tar stains, dead insects, bird droppings (powerful alkaline action) and also resin and pollen from trees and bushes all contain substances which could damage the paint surface after a period of time
(stains, blistering, caustic burns, peeling off of the top paint layer).
In industrial areas, airborne fly ash, lime, oily soot, acid rain or sulphur dioxide as well as other impurities in the air are bound to attack the paintwork if not cleaned with sufficient regularity, though in most cases only the horizontal panel surfaces are affected.
In coastal regions the high salt content and humidity of the air encourages more rapid corrosion.
In the case of mechanical loads caused by sand, road salt, stone chippings or similar, the paint surface may be broken and corrosion may then be able to develop under the paint, and spread out from the damaged areas.
Awareness of these negative environmental effects on the paintwork has stimulated motor vehicle and paint manufacturers to increase the durability and strength of their paints wherever possible.
BMW Service stations supply factorytested Original BMW car care products for all general work of this kind which you intend to carry out yourself.
Care of paintwork
Washing the car once a week will prevent harmful substances from causing long-term damage to the paint finish, particularly if the car is parked or driven in regions where atmospheric pollution levels are high or natural impurities occur in the air (sap from trees, pollen).
Please remove particularly aggressive substances immediately, or else the paint may be attacked or discoloured.
Such substances include spilled fuel, oil, grease, brake fluid or bird droppings.
After washing, residual dirt will be clearly visible. It should be removed without delay, using cleaning-grade benzene or white spirit on a clean cloth or wadding. Remove tar stains with a suitable tar remover, but do not apply this product to lenses and headlight covers. Finally, apply a paint preserving product to the treated areas.

Cleaning and care products can be obtained from BMW Service.

Care of the car
Car wash
A new BMW can be put through an automatic car wash, or washed by hand, immediately.
However, do not wash the car in the sun, immediately after it has stood in the sun or when the engine compartment lid is still warm, in order to avoid blotches on the paintwork.
If an automatic car wash is used, make sure that d d add-on body elementssuch as spoilers cannot be damaged. If in doubt, consult the car wash operator first.
The brush pressure must be as low as possible, and the car wash should operate with ample rinsing water.
Before washing the car, it is best to soak and wash off dead insects.
a
If a steam jet or high-pressure washer is used, make sure that it is held sufficiently far away from the car's panel surfaces. If it is held too near or if the pressure is excessive, the bodywork could either become damaged immediately or eventual damage prompted. In addition, water could penetrate various components on the car and cause long-term damage or failure.
c
Body areas not always reached effectively by the car wash brushes, such as door sills, door seams and panel gaps, should be cleaned by hand.
During the winter months in particular, wash the car more frequently. Severe dirt deposits and road salt are difficult to remove and tend to damage the paintwork if not attended to promptly.
a
After the car has been washed, the brakes may be damp and therefore less efficient. Dry the brake discs by applying them briefly as soon as the car is driven.
c
After washing, residual dirt will be clearly visible. It should be removed without delay, using cleaning-grade benzene or white spirit on a clean cloth or wadding. Clean off tar stains with a tar remover.
Finally, apply a paint protection product to the treated areas.
Protecting the paintwork
Polish the paintwork only with products containing Carnauba or synthetic waxes.
A sure sign that the paintwork needs protective treatment is when water no longer forms large droplets and rolls off the surface. Depending on how and where the car is used, this can be the case after only 3 to 4 months.
Remove care product residues and silicone from the windscreen with glass cleaner.

Care of the car
Touching in paint damage
Minor paint damage can be touched in with a BMW paint spray can or a
BMW paint pencil, or repaired with
BMW paint film.
Your car's paint colour is stated on a label close to its type plate, and also on the first page of the Service Booklet.
Scratches and damage caused by flying stones must be repaired immediately, to prevent rust from forming.
If any areas of the body have already started to rust as a result of paint damage, clean them with a wire brush and apply a rust inhibitor or converter (protect the eyes and skin.) Allow to act for several minutes, then rinse off with water and allow the treated area to dry thoroughly. Apply primer and allow this to dry thoroughly, then apply the top coat. After a few days, polish the repainted areas and apply paint protection.
More widespread paint damage should be entrusted to BMW Service, which can repair it expertly in accordance with the manufacturer's specifications and using Original BMW paint materials.
Care of special components
Light alloy wheels should be treated with wheel cleaner, but do not use products which are of an aggressive nature, contain acid or abrasives or are strongly alkaline. Steam jets used to clean the wheels should not reach a temperature of more than 60 6 . (In all cases, comply with the manufacturer's instructions.)
The insides of the windows and the mirror glasses can be cleaned with a glass cleaner which leaves no smears.
Never clean mirror glasses with products containing quartz or similar abrasive polishing pastes.
Plastic parts, imitation leather upholstery or trim, roof linings, light glasses and parts sprayed with matt black paint must be cleaned with water, to which a car shampoo can be added if required.
Do not allow the roof lining to become wet right through. If necessary, treat plastic parts with a plastics cleaner.
Never use solvents such as nitro thinners, cold cleansers, fuel or similar.
Apart from water, treat rubber parts only with rubber care products or silicone spray.
Clean the wiper blades with soapy water. They should be renewed twice a year (before and after the winter season).
Seat belts should only be cleaned with mild soap suds (without removing them from the car). Do not dry-clean or use chemical products, or the fabric may be weakened.
Never allow automatic seat belts to retract unless they are dry. Dirt on the seat belts can interfere with the action of the reel and represent a safety hazard.

Care of the car
Floor carpets and mats
*
can be treated with a car interior cleaner if very dirty.
The floor mats can be taken out of the car to enable the interior to be cleaned more thoroughly.
Care of upholstery
The pressure areas which occur when cloth seats are in regular daily use can be restored by brushing against the pile direction with a slightly moistened brush.
The tendency of the pile to lie in a particular direction on velour upholstery is not a quality defect and, just as on home textiles or clothing, cannot be avoided.
Remove fluff from cloth upholstery and rubbed-in threads or scraps of cloth or suede with a suitable fluff roller or burr brush. A cleaning glove is available to remove particularly obstinate fluff.
Stains and fairly large areas of dirt should be cleaned off without delay, using lukewarm water and an interior cleaner, stain remover or cleaninggrade benzene. Brush the fabric afterwards to restore its appearance.
Cover the seats if exposed to hot summer sun for lengthy periods, so that the upholstery does not fade.
The build-up of a static electrical charge on the seats, particularly if atmospheric humidity is low, can give the occupants an unpleasant electric shock if they touch metal parts of the car after leaving it. Although this is not dangerous in any way, it can be avoided by touching a bare or polished metal part of the car while getting out.
If necessary, anti-static products can be used to eliminate this effect to a large extent.

Care of the car
Care of leather
The leather
*
used by BMW is a natural product of the highest quality, processed by the very latest methods, and will remain in good condition for many years if correctly treated.
Since leather is an absolutely natural product, its characteristics and certain restrictions on its use and special care precautions must be noted.
Regular cleaning and care are needed, since dust and dirt, for instance from the roads, collect in pores and creases, cause severe abrasion and can lead to the leather surface becoming prematurely brittle.
If exposed to strong sunlight when the car is parked for a lengthy period, leather-upholstered seats should be covered or the windows blanked off to prevent fading.
To clean, slightly moisten a cotton or woollen cloth with water and rub the leather surface gently without allowing moisture to collect in the seams. Dry and rub down with a clean, soft cloth.
Leather that has become very dirty can be cleaned with a mild detergent containing no brighteners (2 tablespoons in
1 litre of water). Dab grease or oil stains carefully with cleaning-grade benzene, without rubbing them hard.
After cleaning, leather surfaces should be treated with a suitable leather care product
*
to protect them and prevent the build-up of a static electrical charge. Shake well and apply a thin coating with a soft cloth. Allow to dry and rub with a clean, soft cloth.
In normal conditions, repeat this treatment every six months.
b
BMW Service can supply suitable car-care products.
c a
Keep cleaning products out of the reach of children. Many products are toxic or flammable, and therefore hazardous in use. Before using any such product, study and comply with the instructions supplied with it, and note any warnings or precautions stated on the pack.
When cleaning the car's interior, always open a door or window. Never use products or solvents not specified for cleaning the car.

Fuel consumption is determined in accordance with standardised test procedures (93/116/EU). It is by no means identical with the car's average consumption, which depends on a variety of factors such as driving style, load, road condition, traffic density and flow, the weather, tyre pressures etc. Engine power output and the car's performance are measured in accordance with condiions laid down in 80/1269/EU and DIN 70020 (with the car to standard specification). This standard also specifies the permitted tolerances. Additional equipment (optional extras) can have a significant effect on performance and consumption, since it usually increases the car's weight and causes the aerodynamic drag coefficient ( c ) to deteriorate (for instance roof racks, wider tyres, additional mirrors etc.).
