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.

What to do if …
Problem
Possible cause
Suggested solution
H
The yellow warning lamp for the
tire pressure monitoring system
comes on.
The tire pressure monitoring system de-
tects a loss of pressure in at least one tire.
Bring the vehicle to a halt, avoiding
abrupt steering and braking maneuvers.
Observe the traffic situation around you.
Take note of the messages in the multi-
function display.
The warning lamp goes out once the tire
pressure monitoring system has been reac-
tivated after the tire inflation pressures
have been corrected.
Warning!
G
When the tire pressure monitoring system
warning light is lit, one or more of your tires
is significantly under-inflated. You should
stop and check your tires as soon as possi-
ble, and inflate them to the proper pressure
as indicated on the vehicle’s tire information
placard. Driving on a significantly under-in-
flated tire causes the tire to overheat and
can lead to tire failure.
Under-inflation also reduces fuel efficiency
and tire tread life, and may affect the vehi-
cle’s handling and stopping ability. Each tire,
including the spare, should be checked
monthly when cold and set to the recom-
mended inflation pressure as specified in
the vehicle placard and owner’s manual.
iThe recommended tire inflation pres-
sures for your vehicle can be found on
the placard on the driver’s door B-pillar
or the inside of the fuel filler flap, not in
the owner’s manual.

The dimensions of the spare wheel
(Minispare wheel or collapsible tire) are dif-
ferent from those of the road wheels. As a
result, the vehicle handling characteristics
change when driving with a spare wheel
mounted.
The spare wheel should only be used tempo-
rarily, and replaced with a regular road
wheel as quickly as possible.
