Cleaning and care of the vehicle
While in operation, even while parked, your 
vehicle is subjected to varying external in-
fluences which, if gone unchecked, can at-
tack the paintwork as well as the 
underbody and cause lasting damage.Such damage is caused not only by ex-
treme and varying climatic conditions, but 
also by:
Air pollution
Road salt
Tar
Gravel and stone chipping
To avoid paint damage, you should imme-
diately remove:
Grease and oil
Fuel
Coolant
Brake fluid
Bird droppings
Insects
Tree resins, etc.
Frequent washing reduces and / or elimi-
nates the aggressiveness and potency of 
the above adverse influences.More frequent washings are necessary to 
deal with unfavorable conditions:
near the ocean
in industrial areas (smoke, exhaust 
emissions)
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 corrosion.
In doing so, do not neglect the underbody 
of the vehicle. A prerequisite for a thor-
ough check is a washing of the underbody 
followed by a thorough inspection. Dam-
aged areas need to be re-undercoated.
Your vehicle has been treated at the facto-
ry with a wax-base rustproofing in the body 
cavities which will last 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 ap-
plied later.
Warning!
G
Many cleaning products can be hazardous. 
Some are poisonous, others are flammable. 
Always follow the instructions on the partic-
ular container. Always open your vehicle’s 
doors or windows when cleaning the inside.
Never use fluids or solvents that are not de-
signed for cleaning your vehicle.

356 Practical hintsWhat to do if …When the message 
Add 1 qt engine oil 
at next refueling (Canada: 
1l
) appears 
while the engine is running and at 
operating temperature, the engine oil level 
has dropped to approximately the 
minimum level.When this occurs, the warning will first 
come on intermittently and then stay on if 
the oil level drops further.
If no oil leaks are noted, continue to drive 
to the nearest service station where the 
engine oil should be topped to the required 
level with an approved oil specified in the 
Factory Approved Service Products pam-
phlet.

382 Practical hintsReplacing bulbs
Notes on bulb replacement
Only use 12-volt bulbs of the same type 
and with the specified watt rating. 
Switch the lights off before changing a 
bulb to prevent short circuits. 
Always use a clean lint-free cloth when 
handling bulbs. 
Your hands should be dry and free of oil 
and grease.
If the newly installed bulb does not 
come on, visit an authorized 
Mercedes-Benz Center.Have the LEDs and bulbs for the following 
lamps replaced by an authorized 
Mercedes-Benz Center:
the additional turn signals in the exteri-
or rear view mirrors
the high mounted brake lamp
the brake lamps
the parking lamps and the side marker 
lamps in the tail lamp unit
the rear fog lamps
the low beam (Xenon or Bi-Xenon*) 
lamps
the front fog lamps
Warning!
G
Bulbs and bulb sockets can be very hot. Al-
low the lamp to cool down before changing 
a bulb.
Keep bulbs out of reach of children.
Halogen lamps contain pressurized gas. A 
bulb can explode if you:
touch or move it when hot
drop the bulb
scratch the bulb
Wear eye and hand protection.
Because of high voltage in Xenon lamps, it is 
dangerous to replace the bulb or repair the 
lamp and its components. We recommend 
that you have such work done by a qualified 
technician.
iHave the headlamp adjustment 
checked regularly.
