Information on M+S tires
& WARNING Risk of accident caused by
incorrect wheel and tire dimensions
The wheel or tire sizes and the tire type of the
emergency spare wheel or spare wheel and the
wheel to be replaced may differ. The emer-
gency spare wheel or spare wheel can signifi-
cantly impair driving characteristics of the vehi-
cle.
To prevent hazardous situations:
Drive carefully.
#
Never install more than one emergency
#
spare wheel or spare wheel that differs in
size.
Only use an emergency spare wheel or
#
spare wheel briefly.
Do not deactivate ESP
#
Have the emergency spare wheel or
#
spare wheel of a different size replaced
at the nearest qualified specialist work-
shop. The new wheel must have the cor-
rect dimensions.
& WARNING Risk of an accident due to
insufficient tire tread
M+S tires with a tread depth of less than ãin
(4 mm) are not suitable for use in winter and
do not provide sufficient grip.
M+S tires with a tread depth of less than
#
ãin (4 mm) must be replaced immedi-
ately.
At temperatures below 50 °F (10 °C) use winter
tires or all-season tires marked M+S.
Only winter tires bearing the i snowflake sym-
bol in addition to the M+S marking provide the
best possible grip in wintry road conditions.
Only these tires allow driving safety systems such
®
as ABS and ESP
to also function optimally in win-
ter. These tires have been developed specifically
for driving in snow.
Use M+S tires of the same make and tread pattern
on all wheels to maintain safe handling character-
istics.
Observe the maximum permissible speed specified
for the mounted M+S tires(
/
If you install M+S tires that have a lower maximum
permissible speed than the maximum design
speed of the vehicle, affix an appropriate informa-
tion label in the driver's field of vision. You can
obtain this at a qualified specialist workshop.
After you mounted the M+S tires, do the following:

Notes on snow chains
& WARNING Risk of accident due to incor-
rectly installed snow chains
If you have installed snow chains on the front
wheels, they may drag against the vehicle body
or chassis components.
Never install snow chains on the front
#
wheels.
Only install snow chains on the rear
#
wheels in pairs.
& WARNING Risk of accident due to unsuita-
ble snow chains
Commercially available snow chains can come
loose and damage chassis components or
brake hoses.
Only install snow chains that have been
#
approved by Mercedes-Benz for these
tires.
& WARNING Risk of accident due to snow
chains breaking
If you drive too fast with snow chains, they can
break, injure other persons, and damage the
vehicle.
Observe the maximum permissible speed
#
for operation with snow chains.
* NOTE Damage to the wheel trim from
mounted snow chains
If snow chains are mounted to steel wheels,
the wheel trims can be damaged.
Remove the wheel trims of steel wheels
#
before mounting snow chains.
