Winter driving
Have your vehicle winterproofed at a quali-
fied specialist workshop, e.g. a Mercedes-
Benz Service Centre, at the onset of win-
ter. This service includes the following:
I
Oil change, if the current engine oil
used has not been approved for winter
use
I
The antifreeze/anti-corrosion concen-
tration in the coolant is checked
I
The addition of a concentrated cleaning
agent to the water in the windscreen
washer/headlamp cleaning system
I
Battery check
I
A tyre change
Prior to the onset of winter, ensure that
snow chains are available in the vehicle.
You will find information about diesel fuel
for use at low outside temperatures in the
“Operation” section (
e page 240).
Please also observe the information about
winter driving (
e page 175).
Winter tyres
Use winter tyres at temperatures below
+7 °C and on snow or ice-covered roads.
Only then may the ABS, ASR, BAS, AAS
and ESP
®
driving safety systems operate
to optimum effect.
Use winter tyres of the same make and
tread on all wheels to maintain safe han-
dling characteristics.
G
Risk of accident
You must replace winter tyres with a tread
depth of less than 4 mm immediately. These
tyres are unsuitable for use in winter and no
longer provide sufficient grip. This could
cause you to lose control of your vehicle
and cause an accident.
Always observe the maximum permitted
speed specified for the winter tyres you
have fitted. If you fit winter tyres which
have a lower maximum permitted speed
than that of the vehicle, affix an appropri-
ate warning sign in the driver’s field of vi-
sion. This is available at any qualified spe-
cialist workshop, e.g. your Mercedes-Benz
Service Centre.
