Winter driving
Have your vehicle winterized at your authorized 
Mercedes-Benz Center before the onset of winter.
•Change the engine oil if the engine contains an oil 
which is not approved for winter operation. For 
viscosity (SAE/CCMC class) and filling quantity, see 
page284.
•Check engine coolant anticorrosion/antifreeze 
concentration.
•Additive for the windshield washer and headlamp 
cleaning system: Add MB Concentrate “S” to a 
premixed windshield washer solvent/antifreeze 
which is formulated for below freezing temperatures 
see page238.
•Test battery: Battery capacity drops with decreasing 
ambient temperature. A well charged battery helps 
to ensure that the engine can be started, even at low 
ambient temperatures.
•Tires: We recommend M+S rated radial-ply tires on 
all four wheels for the winter season. Observe 
permissible maximum speed for M+S rated 
radial-ply tires and the legal speed limit.In winter operation, the maximum effectiveness of the 
antilock brake system (ABS) or of the electronic stability 
program (ESP) can only be achieved with M+S rated 
radial-ply tires and / or snow chains recommended by 
Mercedes-Benz. Snow chains maximize performance.
For driving instructions with snow chains, see page190.
Deep water
Caution!
Do not drive through flooded areas or water of unknown 
depth.
If you must drive through deep water, drive slowly to 
prevent water from entering the engine compartment or 
passenger compartment, being ingested by the air 
intake, possibly causing damage to electrical 
components or wiring, to engine or transmission that is 
not covered by the Mercedes-Benz Limited Warranty.

Malfunction and warning messages
Te ch n ica l

cluster displayPractical hints Car care Index LIGHTING SYSTEMWhen the message appears after starting the engine, or 
if it comes on while driving, this indicates a failure in 
the parking lamp, taillamp, stop lamp, or low beam 
headlamp. See page256 for instructions on replacing 
bulbs.
If an exterior lamp fails, the message will appear only 
when that lamp is switched on.
If a brake lamp fails, the message will appear when 
applying the brake and stays on until the engine is 
turned off.
Note:
If additional lighting is installed (e.g. auxiliary 
headlamps etc.) be certain to connect into the fuse 
before the failure indicator monitoring unit order to 
avoid damaging the system.

WA S H E R  F L U I DWhen this message appears while the engine is 
running, the level of the reservoir has dropped to 
approx. 
1/3 of the total volume. The reservoir should be 
refilled with the prescribed mixture of MB Windshield 
Washer Concentrate “S” and water or the Concentrate 
and commercially available premixed windshield 
washer solvent/antifreeze, depending on ambient 
temperature, at the next opportunity. The reservoir for 
the windshield and headlamp washer systems is located 
in the engine compartment.

Bulbs
Headlamp adjustment
Correct headlamp adjustment is extremely important. 
Check and readjust headlamps at regular intervals and 
when a bulb has been replaced.
For adjusting headlamp aim see page261.
Replacing bulbsNotes:
To prevent a possible electrical short circuit, switch off 
lamp prior to replacing a bulb.
When replacing bulbs, install only 12 volt bulbs with 
the specified watt rating.
When replacing halogen bulbs do not touch glass 
portion of bulb with bare hands. Use plain paper or a 
clean cloth.
Warning!
Bulbs and bulb holders can be very hot. Allow the 
lamp to cool down before changing a bulb.
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.
Wa r n i n g !
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.
