Traveling Abroad; Winter Driving; Tire Chains - Mercedes-Benz 420 SEL 1989 Owner's Manual

Traveling Abroad

Abroad, there is a widely-spread
MERCEDES-BENZ service network at
your disposal. If you plan to travel into
areas which are not listed in the index
of your dealer directory, you should
request pertinent information from
your authorized MERCEDES-BENZ
dealer.

Winter Driving

Have your car winterized at your
authorized MERCEDES-BENZ
dealer before the onset of winter.
• Engine oil change: If "year-round"
multigrade engine oil is not used,
be sure to use an SAE grade
based on ambient temperature.
For recommended engine oil vis­
cosities refer to " Fuels, Coolants,
Lubricants, etc." and last page.
• Check engine coolant anticorro­
sion/antifreeze concentration.
• Additive for the windshield washer
and headlamp cleaning system:
Add MB Concentrate "S" to the
premixed windshield washer sol­
vent/anti-freeze which is formu­
lated for below freezing tempera­
tures (see page 47).
• 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 win­
ter season. Observe permissible
maximum speed for M+S radial
tires and the legal speed limit.

Tire Chains

Use only tire 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. Adhere to the manufac­
turer's mounting instructions.
After driving a short distance retighten
the mounted chains.
Tire 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 18.
