Winter driving
Winter driving
Before the onset of winter, have your vehi-
cle winterized at an authorized
Mercedes-Benz Center. This service in-
cludes:
Check of anticorrosion and antifreeze
concentration
Addition of cleaning concentrate to the
water of the windshield and headlamp
cleaning system
Add MB Concentrate “S” to a premixed
windshield washer solvent / antifreeze
which is formulated for temperatures
below freezing point (
page 467).
Battery test
Battery capacity drops with decreasing
ambient temperature. A well charged
battery helps to make sure that the en-
gine can be started and the SBC brake
system will be fully operational, even at
low ambient temperatures.
Tire change
Mercedes-Benz recommends M+S rat-
ed radial-ply tires with a minimum tread
depth of approximately
1/6 in (4 mm)
on all four wheels for the winter sea-
son.
Winter tires
Always use winter tires at temperatures
below 45°F (7°C) and whenever wintry
road conditions prevail. Use of winter tires
is the only way to achieve the maximum ef-
fectiveness of the ABS, ESP and 4MATIC in
winter operation.
For safe handling, make sure that all
mounted winter tires are of the same make
and have the same tread design.Always observe the speed rating of the
winter tires installed on your vehicle. If the
maximum speed for which your tires are
rated is below the speed rating of your ve-
hicle, you must place a notice to this effect
where it will be seen by the driver. Such no-
tices are available at your tire dealer or any
authorized Mercedes-Benz Center.Warning!
G
Winter tires with a tread depth of less than 1/6in (4 mm) must be replaced. They are no
longer suitable for winter operation.
Warning!
G
If you use your spare tire when winter tires
are fitted on the other wheels, be aware that
the difference in tire characteristics may
very well impair turning stability and that
overall driving stability may be reduced.
Adapt your driving style accordingly.
Have the spare tire replaced with a winter
tire at the nearest authorized
Mercedes-Benz Center.

Do not drive with a flat tire. A flat tire affects
the ability to steer or brake the vehicle.
You may lose control of the vehicle. Contin-
