Winter Driving; Snow Chains - Mercedes-Benz 350 SDL Owner's Manual

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 "Fuels, Coolants,
Lubricants, etc." page 100.
• For diesel fuels, refer to page 103
and last page.
• Check engine coolant anticorro­
sion/antifreeze concentration.
• Additive for the windshield washer
and headlamp cleaning systems:
Add MB Concentrate "S" to the
premixed windshield washer
solvent/antifreeze which is
formulated for below freezing
temperatures (see page 46).
• 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
tires on all four wheels for the
winter season. Observe permissi­
ble maximum speed for M+S
radial 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 house­
hold 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.

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 to the manufac­
turer's mounting instructions.
After driving a short distance retighten
the mounted chains.
Snow chains should only be driven on
snow at speeds not to exceed
50 km/h (30 mph). Remove chains as
soon as possible when driving on
roads without snow.
For tips on driving on slippery winter
roads refer to page 17.
