Note:
The windshield washer reservoir, hoses and nozzles are 
automatically heated.
For windshield and headlamp washer fluid mixing ratio 
see page 263.
Windshield wiper smears
If the windshield wiper smears the windshield, even 
during rain, activate the washer system as often as 
necessary. The fluid in the washer reservoir should be 
mixed in the correct ratio.Blocked windshield wiper
If the windshield wiper becomes blocked (for example, 
due to snow), switch off the wiper.
For safety reasons before removing ice or snow, remove 
electronic key from steering lock. Remove blockage.
Activate combination switch again (electronic key in 
steering lock position 1).

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 page 318.
•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 page 263.
•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.
Note:
In winter operation, the maximum effectiveness of the 
antilock brake system (ABS) or 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.
Block heater (for Canada only)
The engine is equipped with a block heater.
The electrical cable may be installed at your authorized 
Mercedes-Benz Center.

cluster displayPractical hints Car care Index LIGHTING SYSTEMWhen the message appears after starting the engine, or 
if it come on while driving, this indicates a failure in the 
parking lamp, taillamp, stop lamp, or low beam 
headlamp. See page 285 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.
