Driving Instructions
Warning !
If you feel a sudden significant vibration or ride disturbance, or you suspect that possible damage
to your vehicle has occurred, you should turn on the hazard flashers, carefully slow down, and drive with

caution to an area which is a safe distance from the roadway.
Inspect the tires and under the vehicle for possible dama ge. If the vehicle or tires appear unsafe, have
it towed to the nearest Mercedes-Benz or tire dealer for repairs.


Power Assistance
Warning !
When the engine is not running, the brake and steering systems are without power assistance.
Under these circumstances, a much greater effo rt is necessary to stop or steer the vehicle.



Brakes
Warning !
After driving in heavy rain for some time without applying the brakes or through water deep enough to
wet brake components, the first braking action may be somewhat reduced and increased pedal
pressure may be necessary. Be sure to maintain a safe distance from vehicles in front.

Resting your foot on the brake pedal will cause excessive and premature wear of the brake pads.
It can also result in the brakes overheating th ereby significantly reducing their effectiveness.
It may not be possible to stop the car in sufficient time to avoid an accident.


The condition of the parking brake system is checked eac h time the car is in the shop for the required service.

If the parking brake is released and the brake warning lamp in the instrument cluster stays on, the brake fluid level in
the reservoir is too low. Brake pad wear or a leak in the system may be the reason for low brake fluid in the reservoir.

Have the brake system inspected at an aut horized Mercedes-Benz dealer immediately.
All checks and maintenance work on the brake system s hould be carried out by an authorized Mercedes-Benz dealer.
Install only brake pads and brake fluid recommended by Mercedes-Benz.


Warning !
If other than recommended brake pads are installed, or other than recommended brake fluid is used, the
braking properties of the vehicle can be degraded to an extent that safe braking is substantially impaired.

This could result in an accident.


Caution !
When driving down long and steep grades, relieve the load on the brakes by shifting into a lower gear. This helps prevent
overheating of the brakes and reduces brak e pad wear. After hard braking, it is advisable to drive on for some time, rather
than immediately parking, so the air stream will cool down the brakes faster.

Exterior Lamp Failure Indicator Lamp
With the electronic key in steering lock position 2, an indicator lamp comes on. It should go out when the engine is
running. If the warning lamp does not go out after starting the engine, or if it comes on while driving, this lamp
indicates a failure in the parking lamp, taillamp, stop lamp, or low beam headlamp. If an exterior lamp fails, the
indicator lamp will come on only when that lamp is switched on. If a brake lamp fails, the lamp failure indicator will
come on when applying the brake and st ay on until the engine is turned off.

Note:
If additional lighting equipment is installed (e.g. auxiliary headl amps etc.) be certain to connect into the fuse before
the failure indicator monitoring unit in order to avoid damaging the system.


Brake Pad Wear Indicator Lamp
With the electronic key in steering lock position 2, the brake pad wear indicator lamp comes on for approximately 30
seconds. It goes out when the engine is running.
If the indicator lamp lights up during braking, this indica tes that the brake pads are worn down. Have the brake
system checked at your authorized Mercedes- Benz dealer as soon as possible.


Brake Warning Lamp
With the electronic key in steering lock position 2, the brake warning lamp will come on. It should go out when the
engine is running. The brake warning lamp will come on:

• when there is insufficient brake fluid in the rese rvoir (engine running and parking brake released), or
• when the parking brake is set (engine running).

Warning !
Driving with the brake warning lamp on can result in an accident. Have your brake system checked
immediately if the brake warning lamp stays on. Don't add brake fluid before checking the brake system.
Overfilling the brake fluid reservoir can result in spilling brake fluid on hot engine parts and the brake fluid
catching fire. You can be seriously burned.

If you find that the minimum mark on the brake fluid reserv oir is reached, have the brake system checked for brake
pad thickness and leaks. To test the brake warning lamp, turn electronic key in steering lock to position 2. The brake
warning lamp comes on, and should go out when the engine is running.

Jump Starting

Warning !
Failure to follow these directions will cause damage to the electronic components, and can lead to a battery
explosion and severe injury or death. Never lean over batteries while connecting or jump starting, 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 ar ea with water, and seek medical help if necessary.
A battery will also produce hydrogen gas, which is flammable and very explosive. Keep flames or sparks
away from battery, avoid improper connection of jumper cables, smoking etc.. Read all instructions before
proceeding.

If the battery is discharged, the engine should be started with jumper cables and the (12 V) battery of another vehicle.
The battery is located in the trunk under the trunk floor.

Proceed as follows:
1 . Position the vehicle with the charged battery so that the jumper cables will reach, but never
let the vehicles touch. Make sure the jump er cables do not have loose or missing insulation.
2. On both vehicles:
• Turn off engine and all lights and acce ssories, except hazard warning flashers or
work lights.
• Apply parking brake and shift selector lever to position "P".

Important !
3. Clamp one end of the first jumper cable to the positive (+) terminal of the discharged
battery and the other end to the positive (+ ) terminal of the charged battery. Make sure
the cable clamps do not touch any other metal parts.
4. Clamp one end of the second jumper cable to the grounded negative (-) terminal of the
charged battery and the final connection to the negative (-) terminal of the discharged battery.


Important !
5. Start engine of the vehicle with the charged battery and run at high idle. Make sure the
cables are not on or near pulleys, fans, or other parts that will move when the engine is
started. Allow the discharged battery to charge for a few minutes. Start engine of the
disabled vehicle in the usual manner.
6. After the engine has started, remove jumper cables exactly reversing the above
installation sequence, starting with the last connection made first. When removing each
clamp, make sure that it does not touch any other metal while the other end is still attached.


Important !
A discharged battery can freeze at approx. +14°F (-10°C ). In that case, it must be thawed out before
jumper cables are used. A frozen battery can explode and cause personal injury.

Jumper cable specifications:
• Minimum cable cross-section of 25 mm
2 or approx. 2 AWG
• Maximum length of 11.5 ft. (3.5 m).

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, insects, tree resins etc. should be removed immediately to avoid paint damage. Frequent
washing reduces and/or eliminates the aggr essiveness 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 t horough check is a washing of the underbody followed
by a thorough inspection. Damage d areas need to be reundercoated.
Your vehicle has been treated at the factory with a wax-base rustproofing in the body cavities which
will last for the lifetime of t he vehicle. Post-production treatment is neither necessary nor
recommended by Mercedes-Be nz because of the possibility of incompatibility between materials
used in the production proc ess 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 late st technology. You can obtain Mercedes- Benz
approved 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" in formation as well as references to Mercedes-Benz
approved car care products. Additional information can be found in the booklet titled "Car Care".


Engine Cleaning
Prior to cleaning the engine compartment make sure to protect electrical components and
connectors from the intrusion of water and 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 bushings and joints should be
lubricated. The poly-V-belt and all pulleys should be protected from any wax.


Car Washing
Do not use hot water or wash your car in direct sunlight. Use only a mild car wash detergent, such
as Mercedes-Benz approved Car Shampoo.
Thoroughly spray the car with a diffused jet of wa ter. Direct only a very weak spray towards the
ventilation intake. Use plenty of water an d 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, thi nners 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 beco me more difficult to remove. A tar remover is
recommended.


Window Cleaning
Use a window cleaning solution on all glass surfac es. An automotive glass cleaner is recommended.

Engine Oils
Engine oils are specifically tested for their suitability in our engines. Therefore, use only engine oils recommended by
Mercedes-Benz. Information on recommended brands is av ailable at your authorized Mercedes-Benz dealer. Please
follow service Booklet recommendations for scheduled oil ch anges. Failure to do so could result in engine damage
not covered by the Mercedes-Benz Limited Warranty.


Engine Oil Additives
Do not blend oil additives with engine oil. They may be harmful to the engine operation. Damage or malfunctions
resulting from blending oil additives are not covered by the Mercedes-Benz Limited Warranty.


Air Conditioner Refrigerant
R-134a (HFC) refrigerant and special PAG lubricating oil is used in the air conditioner system. Never use R-12 (CFC)
or mineral based lubricating oil, otherwise damage to the system will occur.


Brake Fluid
During vehicle operation, the boiling poin t of the brake fluid is continuously reduced through the absorption of
moisture from the atmosphere. Under extremely hard operati ng conditions, this moisture content can lead to the
formation of bubbles in the system thus reducing the syste m's efficiency. The brake fluid must therefore be replaced
every two years, preferably in the spring. It is recomm ended to use only brake fluid approved by Mercedes- Benz.
Your authorized Mercedes Benz dealer will provide you with additional information.
