Winter Driving
Have your car winterized at your
authorized Mercedes-Benz dealer
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 class) and
filling quantity, see
Capacities: Fuels, Coolants,
Lubricants etc. in Index.
• 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
Index).
• Test battery: Battery capacity drops
with decreasing ambient
temperature. A well charged battery
ensures that the engine can always
be started, even at low ambient
temperatures.
• Tires: We recommend M + S radial-
ply tires on all four wheels for the
winter season. Observe permissible
maximum speed for M + S radial-
ply tires and the legal speed limit.
• Engine block heater: The engine is
equipped with a block heater. The
electrical cable may be installed
free-of-charge at your authorized
Mercedes-Benz dealer by using the
coupon in the "Owner's Service and
Warranty Policy" booklet. The
coupon is valid for 12 months from
date of vehicle delivery.
After installation, the electrical plug
is located at the side of the radiator
(behind the grill) and can be
plugged into ordinary househould
outlets. One or two hours of
operation is usually sufficient to
pre-warm the engine before starting.
The engine block heater can be left
plugged in overnight, if desired.
Note:
In winter operation, the maximum
effectiveness of the electronic traction
system can only be achieved with M +
S radial-ply tires and/or snow chains
recommended by Mercedes-Benz.
Snow Chains
Use only snow chains that are tested
and recommended by Mercedes-Benz.
Your authorized Mercedes-Benz dealer
will be glad to advise you on this
subject.
Chains should only be used on the rear
wheels. Follow the manufacturer's
mounting instructions.
Snow chains should only be driven on
snow covered roads at speeds not to
exceed 30 mph (50 km/h). Remove
chains as soon as possible when
driving on roads without snow.
For tips on driving on slippery
winter roads, refer to Index.
