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, 
seepage305.
•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 256.
•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 page 209.
Deep water
Caution!
Do not drive through f looded 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.
