The temperature selected with the temperature selector is reached as quickly as possible.

The temperature selector should be left at the desired temperature setting.

The system will not heat or cool any quicker by setting a higher or lower temperature.

The automatic climate control only operates with the engine running.

Higher engine rpm results in higher coolant compressor rpm, thereby increasing cooling capacity

If a higher heating or cooling capacity is required due to extreme outside temperatures, select a higher blower setting.

The automatic climate control removes considerable moisture from the air during operation in the cooling mode.

It is normal for water to drip on the ground through ducts in the underbody.

Note:

Outside air is drawn in through a filter.

Dust particles (up to a certain size) and pollen are filtered out

1 Temperature Selector

Select the desired temperature with the temperature selector.

A basic setting in the white field of the selector is recommended.

The selected temperature is shown in the indicator window 2. With conversion switch 3, the selected temperature can be displayed in either

°C or °F.

Note:

If the temperature control should malfunction, turn the temperature selector to either "10°C" ("50°F") or

"40°C" ("104°F") setting.

10°C (50°F) = Heater turned off

40°C (104°F) = Heater turned on

In these cases, we recommend that you have the system checked at your authorized MERCEDES-BENZ dealer.

Once the alarm system has been armed, the exterior vehicle lamps will flash and the horn will sound intermittently when someone: opens a door, opens the trunk, opens the hood, removes the radio, switches on or bridges the ignition circuit, steps on the brake pedal, opens the storage compartment between the front seats, opens the eyeglasses compartment in the dashboard.

The alarm will last approximately 150 seconds in the form of blinking exterior lamps. At the same time an alarm horn will sound intermittently for 60 seconds, pause for 30 seconds, and repeat for another 60 seconds.

The alarm will stay on even if the activating element (a door, for example) is immediately closed.

Note:

If the radio is removed from its mounting when the anti-theft alarm is armed, the radio will automatically be rendered inoperative! (This is indicated by a dashed line across the display.)

33

Power Seats

The switches are located in each front door.

Turn key in steering lock to position 1 or 2 (with either door open, the power seats can also be operated with the key removed or in steering lock position 0).

Warning!

Do not adjust the driver's seat while driving. Adjusting the seat while driving could cause the driver to lose control of the vehicle.

Adjusting

A Seat cushion

B Backrest

C Head restraint (with shoulder belt height adjustment)

Adjust the head restraint so that the upper portion of the shoulder belt is located as close as possible to the middle of the shoulder. The head restraint can be tilted forward by hand.

Note:

To prevent the backrest from touching the soft top storage compartment cover when the seat cushion is moved back, the backrest will automatically move to a more upright position. When reclining the backrest, the seat cushion will automatically move forward to prevent the backrest from touching the soft top storage compartment cover.

Warning!

Never ride in a moving vehicle with the seat back reclined. Sitting in an excessively reclined position can be dangerous. You could slide under the seat belt in a collision, if you slide under it, the belt would apply force at the abdomen or neck. That could cause serious or even fatal injuries.

In a normal seated position the belts provide the best restraint for the wearer, as they are only then properly located on the body.

The rear storage area should never be occupied by passengers since the vehicle is a 2 seater.

Furthermore, there is a risk of injury in the rear by adjusting the power assisted front seats.

34

Storing Position in Memory

After the seat and head restraint are positioned, push memory button D, release, and within 3 seconds push position button "1". Two additional sets of positions may be stored into memory using position buttons "2" and "3".

Using the same position button, the steering column position and rear view mirror positions will also be stored together with the seat position.

Adjusting steering column see page 39 and mirror see page 56.

Recalling Stored Positions

Press position button "1", "2" or "3" and hold until seat/head restraint/ steering wheel/mirror movement has stopped.

Note:

For safety reasons, the seat/head restraint/steering wheel/mirror movement stops after releasing the position button.

35

Backrest

Folding forward:

Lift lever and fold forwards.

Folding back:

Fold backrest back until it audibly locks in place.

Warning!

The seat belts provide protection only with the backrest locked in place and, therefore, must be locked in place with the vehicle in motion.

Do not drive the car when the seatback is not locked in place.

Note:

If the backrest and seat belt warning lamp does not go out, but is instead lit continuously, then a backrest is not engaged in its lock.

Always provide sufficient room behind the backrest and fold the backrest all the way back until it can be heard locking in place.

The warning lamp goes out as soon as both backrests are locked in place.

If both backrests are locked in place and the warning lamp does not go out, have the system checked at your authorized MERCEDES-BENZ dealer immediately.

36

Orthopedic Seat Backrest

1.

Pressure regulator

2.

Height regulator

Some models may be equipped with orthopedic seats. These seats have an inflatable air cushion built into the backrest to provide additional lumbar support.

The pressure and height regulators are located on the driver's seat on the left, on the passenger's seat on the right.

The amount of cushion height and curvature may be adjusted after turning the key to steering lock position 1 or 2.

The inflation pressure of the air cushion can be varied between position

"0" = without pressure, and position

"4" = maximum pressure, by changing the pressure regulator (1) setting. In addition, the cushion height may be changed to five different settings between position "a" = lowest setting, and "e" = highest setting, by varying the height regulator (2) adjustment.

If the engine is turned off, the last cushion setting is retained in memory, and automatically adjusts the cushion to this setting when the engine is restarted.

37

Heated Seats

The seat heaters can be switched on with the key in steering lock turned to position 1 or 2.

Turning on heater: Press upper half of switch = normal heating mode. One indicator lamp in the switch lights up.

Press lower half of switch = rapid heating mode. Both indicator lamps "in the switch light up.

After approximately 5 minutes in the rapid heating mode, the heater automatically switches to normal operation and only one indicator lamp will stay on.

Turning off heater:

If one indicator lamp is on, press upper half of switch.

If both indicator lamps are on, press lower half of switch.

If left on, the heater automatically turns off after approximately 30 minutes of operation.

Note:

When in operation, the seat heater consumes a large amount of power. It is advisable not to use the seat heater longer than necessary.

The seat heaters may automatically switch off if too many power consumers are switched on at the same time, or if the battery charge is low.

When this occurs, the indicator lamp in the switch will blink (both indicator lamps blink during rapid seat heating).

The seat heaters will switch on again automatically as soon as sufficient voltage is available.

If the blinking of the indicator lamps is distracting to you, the seat heaters can be switched off.

38

Arm Rest

To adjust: Press button (1) and slide arm rest forward or backward.

Adjusting Steering Column

Turn key in steering lock to position 1 or 2 (with either door open, the steering column can be operated with the key removed or in steering lock position 0).

To extend or retract: Move switch (1) in desired direction.

To raise or lower: Move switch (1) in desired direction.

Storing Steering Column

Position in Memory

The steering column position is stored in memory together with the seat/head restraint/mirror position and can be recalled when necessary, see page 35.

39

Seat Belts and Supplemental

Restraint System

Your vehicle is equipped with lapshoulder seat belts, emergency tensioning retractors for the seat belts, driver airbag and knee bolster and passenger airbag and knee bolster.

Important!

Laws in most states and all Canadian provinces require seat belt use.

All states and provinces require use of child restraints that comply with U.S.

Federal Motor Vehicle Safety Standard

213 and Canadian Motor Vehicle

Safety Standard 213.1. We strongly recommend their use.

Seat Belt Warning System

With the key in steering lock position

2, an audible warning sounds for a short time if the driver's seat belt is not fastened.

Warning!

If you are ever in an accident, your injuries can be considerably more severe without your seat belt properly buckled. Without your seat belt buckled, you can hit the interior of the vehicle or be ejected from it.

You can be seriously injured or killed.

In the same crash, the possibility for injury or death is lessened with your seat belt buckled.

The seat belts provide protection only with the backrest locked in place. If the seat belt warning lamp does not go out, but is instead lit continuously, then a backrest is not engaged in its lock.

Never ride in a moving vehicle with the seat back reclined. Sitting in an excessively reclined position can be dangerous. You could slide under the seat belt in a collision. If you slide under it, the belt would apply force at the abdomen or neck. That could cause serious or even fatal injuries.

The seat back and seat belts provide the best restraint when the wearer is in an upright position and belts are properly positioned on the body.

40

1 Latch plate

2 Buckle

3 Release button

Fastening

Pull belt with latch plate (1) across shoulder and lap. Push latch plate (1) into buckle (2) until it clicks. The lap belt should be positioned as low as possible on your hips and not across the abdomen. Do not twist the belt. For safety reasons, avoid adjusting the seat or seat back into positions which could affect the correct seat belt position (see warning on page 43).

Press switch (4) to adjust seat belt so that the shoulder portion is located as close as possible to the middle of your shoulder.

The shoulder portion of the seat belt must be pulled snug and checked for snugness immediately after engaging it and during driving. Tighten the lap portion to a snug fit by pulling shoulder portion up.

41

Unfastening

Push in the red button (3) in the belt buckle (2).

Allow the retractor to completely rewind the seat belt by guiding the latch plate (1).

Operation:

The inertia reel stops the belt from unwinding during sudden vehicle stops or when quickly pulling on the belt.

The locking function of the reel may be checked by quickly pulling on the belt.

The emergency tensioning retractors tighten the fastened seat belts during frontal and front-angled impacts exceeding the first threshold of the

SRS (see page 44).

42

Warning!

• Each occupant should wear their seat belt at all times.

Together with the "SRS", the seat belt offers the best conditions for protection of the body in case of major frontal impact.

• Never wear the shoulder belt under your arm, against your neck or off your shoulder, in a crash, your body would move too far forward. That would increase the chance of head and neck injuries. The belt would also apply too much force to the ribs, this could severely injure internal organs such as your liver or spleen. Position the lap belt as low as possible on your hips and not across the abdomen. If the belt is positioned across your abdomen, it could cause serious injuries in a crash.

• Improperly positioned belts do not provide maximum protection and may cause serious or fatal injuries in case of an accident.

• Infants and small children must be seated in an infant or child restraint system, which is properly secured by the lap belt portion of the lap-shoulder belt

Children could be endangered in an accident if their child restraints are not properly secured in the vehicle.

• Children too big for child restraint systems should use regular seat belts. Position shoulder belt across the chest and shoulder, not the face or neck. A booster seat may be necessary to achieve proper belt positioning.

• Adjust the passenger seat as far as possible rearward from the dashboard, especially if a child restraint is installed.

• Each seat belt should never be used for more than one person at a time.

• Belts should not be worn twisted.

In a crash, you wouldn't have the full width of the belt to take impact forces. The twisted belt against your body could cause injuries.

• Pregnant women should also use the lap-shoulder belt. The lap belt portion should be positioned as low as possible on the hips to avoid any pressure on the abdomen.

For cleaning and care of the seat belts, see page 115.

43

Supplemental Restraint System

(SRS)

The SRS uses two crash severity levels

(thresholds) to activate either the ETR or airbag or both. Activation depends on exceeding the thresholds and fastening of the seat belt.

Seat belt fastened first threshold exceeded: ETR activates second threshold exceeded: airbag also activates

Seat belt not fastened first threshold exceeded: airbag activates, but not ETR

Driver and front passenger systems operate independently from each other.

Emergency Tensioning

Retractor (ETR)

The seat belts are equipped with emergency tensioning retractors. These tensioning retractors are located in each belt's inertia reel and become operationally ready with the key in steering lock position 1 or 2.

The emergency tensioning retractors are designed to activate only when the seat belts are fastened during frontal and front-angled impacts exceeding the first threshold of the SRS. They remove slack from the belts in such a way that the seat belts fit more snugly against the body, restricting its forward movement as much as possible.

In cases of other frontal impacts, rollovers, certain side impacts, rear collisions, or other accidents without frontal forces, the emergency tensioning retractors will not be activated. The driver and passenger will then be protected by the fastened seat belts and inertia reel in the usual manner.

For seat belt and emergency tensioning retractor safety guidelines, see page 48.

44

Airbags

The most effective occupant restraint system yet developed for use in production vehicles is the three point seat belt. In some cases, however, the protective effect of a seat belt can be further enhanced by an airbag. The driver airbag (1) is located in the steering wheel hub. The passenger airbag (2) is located in the dashboard ahead of the passenger. In conjunction with wearing the seat belts with emergency tensioning retractors (4), they provide increased protection for the driver and passenger.

The operational readiness of the airbag system is verified by the indicator lamp

"SRS" (3) in the instrument cluster. If no fault is detected, the lamp will go out after approximately 4 seconds; after the lamp goes out, the system continues to monitor the components and circuitry of the airbag system and will indicate a malfunction by coming on again.

45

The following system components are monitored or undergo a self-check: crash-sensor, airbag ignition circuits, driver and passenger seat belt buckles.

Initially, when the key is turned from steering lock position 0 to positions 1 or 2, malfunctions in the crash-sensor are detected and indicated (the "SRS" indicator lamp stays on longer than 4 seconds).

In the operational mode, after the indicator lamp has gone out following the initial check, interruptions and short circuits in the airbag ignition circuit and in the driver and passenger seat belt buckle harnesses, and low voltage in the entire system are detected and indicated.

In the event a malfunction of the "SRS" is indicated as outlined above, the

"SRS" may not be operational. We strongly recommend that you visit an authorized MERCEDES-BENZ dealer immediately to have the system checked; otherwise the "SRS" may not be activated when needed.

Important!

The airbags are designed to activate only in certain frontal and frontangled impacts (within the shaded area shown in the illustration on page 44). Only during these types of impacts will they provide their supplemental protection. The driver and passenger should always wear the seat belts, otherwise it is not possible for the airbags to provide their intended supplemental protection.

In cases of other frontal impacts, rollovers, certain side impacts, rear collisions, or other accidents without frontal forces, the airbag will not be activated. The driver and passengers will then be protected by the fastened seat belts.

Important!

The "SRS" is designed to reduce the potential of injury in certain frontal and front-angled impacts which may cause injuries, however, no system available today can totally eliminate injuries and fatalities.

The activation of the "SRS" temporarily releases a small amount of dust from the air-bags. This dust, however, is neither injurious to your health, nor does it indicate a fire in the vehicle.

The service life of the airbags extends to the date indicated on the label located on the driver-side door latch post To provide continued reliability after that date, they should be inspected by an authorized

MERCEDES-BENZ dealer at that time and replaced when necessary.

46

Warning!

It is very important for your safety to always be in a properly seated position.

For maximum protection in the event of a collision always be in normal seated position with your back against the seat back. Fasten your seat belt and ensure that it is properly positioned on the body.

Since the airbag inflates with considerable speed and force, a proper seating position will keep you in a safe distance from the airbag:

• Sit properly belted in an upright position with your back against the seat back.

• Do not lean with your head or chest close to the steering wheel or dashboard,

• Adjust the passenger as far as possible rearward from the dashboard, especially when a child restraint is installed.

• Infants and small children should only be seated in an infant or child restraint which is properly secured by the seat belt.

Failure to follow these instructions can result in severe injuries to you or other occupants.

47

Safety Guidelines for the Seat Belt,

Emergency Tensioning

Retractor and Airbag

Warning!

• Damaged belts or belts that were highly stressed in an accident must be replaced and their anchoring points must also be checked. Use only belts installed or supplied by an authorized MERCEDES-BENZ dealer.

• Do not pass belts over sharp edges.

• Do not make any modification that could change the effectiveness of the belts.

• The "SRS" is designed to function on a one-time-only basis. An airbag or emergency tensioning retractor (ETR) that was activated must be replaced.

• No modifications of any kind may be made to any components or wiring of the

"SRS". This includes the installation of additional trim material, badges, etc. over the steering wheel hub or front passenger airbag cover and installation of additional electrical/electronic equipment on or neat "SRS" components and wiring.

• Several airbag system components at the steering wheel get hot after the airbag has inflated. Don't try to touch them.

• Improper work on the system, including incorrect installation and removal, can lead to possible injury through an uncontrolled activation of the

"SRS".

• In addition, through improper work there is the risk of rendering the "SRS" inoperative. Work on the "SRS" must therefore only be performed by an authorized

MERCEDES-BENZ dealer.

• When scrapping the airbag unit or emergency tensioning retractor, it is mandatory to follow our safety instructions.

These instructions are available at your authorized MERCEDES-

BENZ dealer.

When you sell the vehicle we strongly urge you to give notice to the subsequent owner that it is equipped with an "SRS" by alerting him to the applicable section in the

Owner's Manual.

48

Infants and Child Restraint Systems

We recommend that all infants and children be restrained at all times while the vehicle is in motion.

Important!

The use of infant or child restraints is required by law in all 50 states and all

Canadian provinces.

Infants and small children should be seated in an infant or child restraint system, which is properly secured by the lap belt portion of the lap-shoulder belt, and that complies-with U.S.

Federal Motor Safety Standard 213 and

Canadian Motor Vehicle Safety

Standard 213.1.

A statement by the child restraint manufacturer of compliance with this standard can be found on the instruction label on the restraint and in the instruction manual provided with the restraint.

When using any infant or child restraint system, be sure to carefully read and follow all manufacturer's instructions for installation and use.

Warning!

When the child restraint is not in use, remove it from the car or secure it with the seat belt to prevent the loose child restraint from becoming a projectile in the event of an accident.

Infants and small children should never be held on the lap while the vehicle is in motion. During an accident they would be almost impossible to hold, and could be crushed between the adult and the dashboard.

Infants and small children should never share a seat belt with another occupant. During an accident, they could be crushed between the occupant and seat belt.

Children too big for child restraint systems should use regular seat belts.

Position shoulder belt across the chest and shoulder, not the face or neck. A booster seat may be necessary to achieve proper belt positioning.

U.S.A. Models only

Since 1986 all child restraints comply with U.S. regulations (or FMVSS 213) without the use of a tether strap.

Canada Models only

This vehicle can be equipped with a tether anchorage for use with child restraints that have a top tether strap.

Consult your authorized MERCEDES-

BENZ dealer for installation of this anchorage.

49

Steering Lock

0 Steering is locked when the key is withdrawn and the steering lock is engaged.

The key can be withdrawn only in position 0.

In models equipped with automatic transmission, the key can be removed only with the selector lever in position "P".

With the key removed, the selector lever is locked in position "P".
