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 /CCMC class) and filling
quantity, see Capacities: Fuels,
Coolants, Lubricants etc. in
Index.
• For diesel fuels, refer to 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 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 acceleration slip
control is only achieved with M + S
radial tires.
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.
Vehicles with Acceleration Slip
Control (ASR):
When driving with snow chains, press
the snow chain switch, refer to Index.
