Example
Checking Coolant Level
The coolant level can be checked visually at the transparent coolant reservoir.
To check the coolant level, the vehicle must be parked on level ground.
Check coolant level only when coolant is cold:
The coolant should reach the rib in the filler neck. Also see marking (1) on reservoir.
Warning!
• Use extreme caution when opening the hood if there are any signs of steam or coolant leaking from the cooling system.
• Do not remove pressure cap on coolant reservoir if engine temperature is above 90°C
(194°F). Allow engine to cool down before removing cap. The coolant reservoir contains hot fluid and is under pressure.
• Using a rag, turn cap to first notch to relieve excess pressure.
If opened immediately, hot scalding fluid and steam will be blown out under pressure, possibly causing personal injury,
• Do not spill antifreeze on hot engine parts. Antifreeze contains ethylene glycol which may burn if it comes into contact with hot engine parts. You can be seriously burned.
Adding Coolant
If coolant has to be added, a 50/50 mixture of water and MB anticorrosion/antifreeze should be added.
SL 320:
The drain plugs for the cooling system are located on the right side of the engine block and at the bottom of the radiator.
SL 500, SL 600:
The drain plugs for the cooling system are located on the right and left sides of the engine block and at the bottom of the radiator.
Anticorrosion/antifreeze, see
Coolants in Index.

SL 320
Checking Engine Oil Level
1. Oil dipstick
2. Oil filler cap
To check the engine oil level, park vehicle on level ground, with engine at normal operational temperature.
SL 500
The best time to check the engine oil level is when the oil is warm, such as during a fuel stop.
With the vehicle on level ground, stop the engine and wait a few minutes for the oil to drain back to the oil pan.
SL 600
Oil level must be between the lower (min) and upper(max) mark of the dipstick
Do not overfill engine.
Excessive oil must be drained or siphoned.
For low engine oil level warning lamp, see Index.
104
Automatic Transmission Fluid Level
The transmission has a permanent fill of automatic transmission fluid.
Regular automatic transmission fluid level checks and changes are not required. For this reason the dipstick is omitted.
If you notice fluid leaks or gear shifting malfunctions, have your authorized
Mercedes-Benz dealer check the transmission fluid level.

(1) must be lowered almost to the base
(2) of the jack.
Note:
First remove the vehicle jack, then the spare wheel; reinstall in reverse order.
Warning!
The jack is designed exclusively for jacking up the vehicle at the jack tubes built into either side of the vehicle. Use the jack only to lift the vehicle during a wheel change. Never get beneath the vehicle while it is supported by the jack. Keep hands and feet away from the area under the lifted vehicle. Always firmly set parking brake and block wheels before raising vehicle with jack.
Do not disengage parking brake while the vehicle is raised. Be certain that the jack is always vertical when in use, especially on hills. Always try to use the jack on level surface. Be sure that the jack arm is fully inserted in the jack tube. Always lower the vehicle onto sufficient capacity jackstands before working under the vehicle.
Wheels
Replace rims or tires with the same designation, manufacturer and type as shown on the original part. See your authorized MERCEDES-BENZ dealer for further information.
Warning!
Do not mix different tire construction types (i.e. radial, bias, and bias-belted) on your car because handling may be adversely affected and may result in loss of control.
See your authorized MERCEDES-
BENZ dealer for information on tested and recommended rims and tires for summer and winter operation. They can also offer advice concerning tire service and purchase.
107
Tire Replacement
Front tires should be replaced in sets.
Furthermore - in the event of tire replacement - the spare wheel, if possible, should be used on the rear axle. Rims and tires must be of the same size. For dimensions, see
"Technical Data".
We recommend that you break in new tires for approx. 100 km (60 miles) at moderate speed. It is imperative that the wheel mounting bolts be retightened after approx. 100 to 500 km
(60 -300 miles).
On new vehicles retightening is carried out during the 1st inspection.
Retightening is also necessary whenever wheels are fitted, e.g. when the spare wheel is used for the first time or when a set of wheels with M +
8 tires is installed.
Tightening torque: 110 Nm
(80 ft. lb.)".
For rim and tire specifications, refer to
“Technical Data”.
Warning!
Worn, old tires can cause accidents.
If the tire tread is badly worn, or if the tires have sustained damage, replace them.
When replacing rims, use only genuine MERCEDES-BENZ wheel bolts (identified by Mercedes star) specified for the rim type. Failure to do so can result in the bolts loosening and possibly an accident
Rotating Wheels
The wheels can be rotated according to the degree of tire wear while retaining the same direction of travel.
Rotating, however, should be carried out at the scheduled maintenance intervals, before the characteristic tire wear pattern (shoulder wear on front wheels and tread center wear on rear wheels) becomes visible, as otherwise the driving properties deteriorate.
Important!
Unidirectional snow tires must always be mounted with arrow on tire sidewall pointing in direction of vehicle forward movement.
Note:
Thoroughly clean the inner side of the wheels any time you rotate the wheels or wash the vehicle underside.
The use of retread tires is not recommended. Retread tires may adversely affect the handling characteristics and safety of the vehicle.
Dented or bent rims cause tire pressure loss and damage to the tire beads. For this reason, check rims for damage at regular intervals.
The rim flanges must be checked for wear before a tire is mounted.
Remove burrs, if any.
Check and correct tire inflation pressure after rotating the wheels. For
Tire Inflation Pressure refer to Index
108

"Technical Data".
Changing Wheels
Warning!
Before working on the vehicle, e.g.
when changing wheels, the roll bar should be raised with the switch, and the key be removed from the steering lock, to prevent possible injury.
Move vehicle to a level area which is a safe distance from the roadway.
1. Firmly set parking brake, raise roll bar, and turn on hazard warning flasher.
2. Move selector lever to position "P".
3. While engine is running, depress wheel change switch for level control. The switch and
ADS indicator lamps light up.
4. Turn off engine.
109
3. Prevent vehicle from rolling away by blocking wheels with wheel chocks (not supplied with vehicle) or sizable wood block or stone. When changing a wheel on a hill, place chocks on the downhill side blocking both wheels of the other axle.
On a level road, place one chock in front of and one be hind the wheel that is diagonally opposite to the wheel being changed.
4. Using lug wrench, loosen but do not yet remove the wheel bolts.
5. Remove the protective cover from the jack support tube opening by inserting a screwdriver in the opening and prying it out.
The tube openings are located directly behind the front wheel housings and in front of the rear wheel housings.
6. Insert jack arm fully into the tube hole up to the stop.
Position the jack so that it is always vertical (plumb-line) as seen from the side (see arrow), even if the vehicle is parked on an incline.
7. Jack up the vehicle until the wheel is clear of the ground.
Never start engine while vehicle is raised.
8. Unscrew upper-most wheel bolt and install alignment bolt (1) supplied in the tool kit. Remove the remaining bolts. Keep bolt threads protected from dirt and sand.
9. Remove wheel. Grip wheel from sides. Keep hands from beneath the wheels.
110
10. Clean contact surfaces of wheel and wheel hub. Install spare wheel on wheel hub.
Insert wheel bolts and tighten them slightly.
To avoid paint damage, place wheel flat against hub and hold it there while installing first wheel bolt.
Unscrew the alignment bolt (1) to install the last wheel bolt.
11. Lower car. Remove jack and insert jack tube cover.
Before storing the jack, the jack arm must be lowered almost to the base of the jack. Store the spare wheel first and then the vehicle jack.
Warning!
Always replace wheel bolts that are damaged or rusted.
Never apply oil or grease to wheel bolts.
Damaged wheel hub threads should be repaired immediately.
Incorrect mounting bolts or improperly tightened mounting bolts can cause the wheel to come off. This could cause an accident. Be sure to use the correct mounting bolts.
Important!
When installing new wheels the mounting bolts must be retightened after approx. 60 - 300 miles (100-500 km).
12. Fold wrench together and tighten the five bolts evenly, following the sequence illustrated above, until all bolts are tight.
Observe a tightening torque of
80 ft. lb. (110 Nm).
13. Correct tire pressure.
14. Depress wheel change switch for level control. The switch and ADS indicator lamps will go out.
Warning!
Do not drive the vehicle while the wheel change switch is activated since the vehicle suspension will not function properly.
111
Tire Inflation Pressure
A table (see fuel filler flap) lists the tire inflation pressures specified for
Mercedes Benz recommended tires as well as for the varying operating conditions.
Important!
Tire pressure differs by approx. 1.5 psi
(0.1 bar) per 18°F (10°C) of air temperature change. Keep this in mind when checking tire pressure inside a garage - especially in the winter.
Example:
If garage temperature = approx. + 68 ° F (+ 20 ° C) and ambient temperature = approx. + 32° F (0°C) then the adjusted air pressure = specified air pressure + 3 psi (+ 0.2 bar).
Tire pressures listed for light loads are minimum values offering high driving comfort.
Increased inflation pressures for heavy loads produce favorable handling characteristics with lighter loads and are perfectly permissible. The ride of the vehicle, however, will become somewhat harder.
Tire temperature and pressure increase with the vehicle speed. Tire pressure should therefore only be corrected on cold tires. Correct tire pressure in warm tires only if pressure has dropped below the pressure listed in the table and the respective operating conditions are taken into consideration.
An underinflated tire due to a slow leak (e.g. due to a nail in the tire) may cause damage such as tread separation, bulging etc.. Regular tire pressure checks (including the spare tire) at intervals of no more than 14 days are therefore essential.
If a tire constantly loses air, it should be inspected for damage
Warning!
Do not overinflate tires, overinflating tires can result in sudden deflation
(blowout) because they are more likely to become punctured or damaged by road debris, potholes etc.. Follow recommended inflation pressures.
Do not overload the tires by exceeding the specified vehicle capacity weight (as indicated by the label on the driver's door latch post).
Overloading the tires can overheat them, possibly causing a blowout.
112
Battery
Warning!
Failure to follow these instructions can result in severe injury or death.
Never lean over batteries while connecting, you might get injured.
Battery fluid contains sulfuric acid.
Do not allow this fluid to come in contact with eyes, skin or clothing. In case it does, immediately flush affected area with water and seek medical help if necessary.
A battery will also produce hydrogen gas, which is flammable and explosive. Keep flames or sparks away from battery, avoid improper connection of jumper cables, smoking etc..
The maintenance-free battery is located in the trunk under the right-hand wheel well cover panel.
The service life of the battery is dependent on its condition of charge.
The battery should always be kept sufficiently charged, in order to last an optimum length of time.
Therefore, we strongly recommend that you have the battery charge checked frequently, and corrected if necessary, especially if you use the vehicle less than approximately 200 miles (300 km) per month, mostly for short distance trips, or if it is not used for long periods of time.
Only charge a battery with a battery charger after the battery has been disconnected from the vehicle electrical circuit.
Always disconnect the battery negative lead first and connect last.
When removing and connecting the battery, always make sure that all electrical consumers are off and the key is in steering lock position 0. The battery and its vent tube must always be securely installed when the car is in operation.
While the engine is running the battery terminal clamps must not be loosened or detached, otherwise the generator and other electronic components would be damaged.
Important!
Do not close a door with the windows fully closed while the power supply is interrupted (battery disconnected or empty). Doing so could damage the window frame.
Note:
After reconnecting the battery also resynchronize the Express feature of the power windows and the Adaptive
Damping System (ADS) (see Power
Windows and ADS in Index),
Battery Recycling

Cleaning and Care of the Vehicle
Warning!
Many cleaning products can be hazardous. Some are poisonous, others are flammable. Always follow the instructions on the particular container. Always open your car's doors or windows when cleaning the inside.
Never use fluids or solvents that are not designed for cleaning your car.
In operation, your vehicle is subjected to varying external influences which, if gone unchecked, can attack the paintwork as well as the underbody and cause lasting damage.
Such damage is caused not only by extreme and varying climatic conditions, but also by air pollution, road salt, tar, gravel and stone chipping. Grease and oil, fuel, coolant, brake fluid, bird droppings, tree resins, etc. should be removed immediately to avoid paint damage. Frequent washing, however, reduces and/or eliminates the aggressiveness and potency of the above adverse influences.
More frequent washings are necessary to deal with unfavorable conditions; for example, near the ocean, in industrial areas (smoke, exhaust emissions), or during winter operation.
You should check your vehicle from time to time for stone chipping or other damage. Any damage should be repaired as soon as possible to prevent the start of corrosion.
In doing so, do not neglect the underside of the car. A prerequisite for a thorough check is a washing of the underbody followed by a thorough inspection. Damaged areas need to be reundercoated.
Your vehicle has been treated at the factory with a wax-base rustproofing in the body cavities which will fast for the lifetime of the vehicle. Post-production treatment is neither necessary nor recommended by
MERCEDES-BENZ because of the possibility of incompatibility between materials used in the production process and others applied later.
We have selected car-care products and compiled recommendations which are specially matched to our vehicles and which always reflect the latest technology. You can obtain MB car-care products at your authorized
MERCEDES-BENZ dealer.
Scratches, corrosive deposits, corrosion or damage due to negligent or incorrect care cannot always be removed or repaired with the car-care products recommended here. In such cases it is best to seek aid at your authorized
MERCEDES-BENZ dealer.
The following topics deal with the cleaning and care of your vehicle and give important "how-to" information as well as references to recommended
MB car-care products.
Additional information can be found in the booklet titled "Car Care".
131
Engine Cleaning
Prior to cleaning the engine compartment make sure to protect electrical components and connectors from the intrusion of water or cleaning agents.
Corrosion protection, such as MB
Anticorrosion Wax should be applied to the engine compartment after every engine cleaning. Before applying, all control linkage bushing should be lubricated. The poly-V-belt and all pulleys should be protected from any wax.
Car Washing
Before washing your vehicle, remove insect residues, MB Insect Remover is recommended. Do not use hot water or wash your car in direct sunlight. Use only a mild car wash detergent, such as
MB Autoshampoo.
Thoroughly spray the car with a diffused jet of water. Direct only a very weak spray towards the ventilation intake. Use plenty of water and rinse the sponge and chamois frequently.
Rinse with clear water and thoroughly wipe dry with a chamois. Do not allow cleaning agents to dry on the finish.
If the vehicle has been run through an automatic car wash - in particular one of the older installations - rewipe the recessed sections in the taillamps
(designed to prevent soiling) if necessary. No solvents (fuels, thinners etc.) must be used.
In the winter, thoroughly remove all traces of road salt as soon as possible.
When washing the underbody, do not forget to clean the inner sides of the wheels.
Tar Stains
Quickly remove tar stains before they dry and become more difficult to remove. MB Tar Remover is recommended.
Window Cleaning
Use a window cleaning solution on all glass surfaces. MB Glass Cleaner is recommended.
Wiper Blade
Clean the wiper blade rubber with a clean cloth and detergent solution.
Replace blade twice a year; once before and once after winter.
Headlamp Cleaning System
The condition of the wiper blades is important for satisfactory cleaning of the headlamp lenses. We therefore recommend that the blades be inspected regularly.
Replace damaged wiper blades.
Seat Belts
The webbing must not be treated with chemical cleaning agents. Use only clear, lukewarm water and soap. Do not dry the webbing at temperatures above 176°F (8Q°C) or in direct sunlight.
Warning!
Do not bleach or dye seat belts as this may severely weaken them. In a crash they may not be able to provide adequate protection.
132
Instrument Cluster
Use a gentle dish-washing detergent or mild detergent for delicate fabrics as a washing solution. Wipe with a cloth moistened in lukewarm solution. Do not use scouring agents.
Steering Wheel and Gear
Shift Lever
Wipe with a damp cloth and dry thoroughly or clean with MB Leather
Cleaner.
Upholstery
Using aftermarket seat covers or wearing clothing that have the tendency to give off coloring (e.g.
when wet etc.) may cause the upholstery to become permanently discolored. By lining the seats with a proper intermediate cover, contactdiscoloration will be prevented.
Wipe leather upholstery with a damp cloth and dry thoroughly or clean with
MB Leather Cleaner. Exercise particular care when cleaning perforated leather as its underside should not become wet.
Plastic Parts, Headliner and Rubber Parts
Do not use oil or wax on these parts.
See separate subjects for additional information.
Paintwork, Painted Body
Components
MB-Paint Protector and Sealer should be applied when water drops on the paint surface do not "bead up"; normally in 3 to 5 months depending on climate and washing detergent used.
MB-Paint-Polish should be applied if paint surface shows signs of dirt embedding (i.e. loss of gloss).
MB-Fine Polishing Paste must be used when the paint surface shows signs of excessive fading/ chalking due to lack of care etc..
Do not apply any of these products or wax if your car is parked in the sun or if the hood is still hot.
Use the appropriate MB-Touch-Up
Stick for quick and provisional repairs of minor paint damage (i.e. chips from stones, car doors etc.).
Automatic Antenna
For trouble-free operation of the automatic antenna, we recommend that you clean the antenna mast periodically.
Light Alloy Wheels
Mercedes-Benz approved Wheel Care should be used for regular cleaning of the light alloy wheels.
If possible, clean wheels once a week with Mercedes-Benz approved Wheel
Care, using a soft bristle brush and a strong spray of water.
Follow instructions on container.
Note:
Use only acid-free cleaning materials.
The acid could lead to corrosion.
133
Soft Top
Clean soft top with soft top raised and locked. Lower the soft top into the storage compartment only if the top is completely dry. If the top is kept in the storage compartment for a lengthy period, raise it and air it out with the windows down about every 4 months.
Dry cleaning:
Brush top (always from front to rear) with a soft-bristled brush.
Wet cleaning:
Brush the dry top. Wash with a mild detergent and an ample supply of lukewarm water by wiping with a softbristled brush or sponge from front to rear. Then rinse thoroughly with clear water.
If only parts of the top have been washed, wet the entire top and allow it to air-dry before lowering it into the storage compartment.
Wipe the rear window with a cloth soaked with a mild, non-abrasive detergent, rinse and rub dry.
Do not use sharp-edged instruments for the removal of ice and snow.
Note:
Never run the vehicle through an automatic car wash with the soft top in place as you may damage the soft top material.
Remove bird droppings immediately.
The organic acid damages the material and causes the soft top to leak.
In general, regular spraying or cleansing with clear water is sufficient to keep the top clean.
Wash the top only when heavily soiled.
Caution!
Never use any gasoline, thinner, tar and stain removers, glass cleaner, or similar organic solvents to clean the soft top, plastic window or wind screen.
They will cause damage which is not covered by the Mercedes-Benz -
Limited Warranty.
Ornamental Moldings
For regular cleaning and care of very dirty chrome-plated parts, use a chrome cleaner.
Wind Screen
Use only water or mild detergent to clean the wind screen.
Hard Plastic Trim Items
Pour MB Plastic Cleaner onto soft lintfree cloth and apply with light pressure.
Headliner
Soft top:
Clean with soft bristle brush, or use a dry-shampoo cleaner in case of excessive dirt.
