Driving with summer tyres
At temperatures below +7 †, summer tyres lose
elasticity and therefore traction and braking
power. Change the tyres on your vehicle to
M+S tyres. Using summer tyres at very cold
temperatures could cause tears to form,
thereby damaging the tyres permanently.
Mercedes-Benz cannot accept responsibility for
this type of damage.
G
WARNING
Damaged tyres can cause tyre inflation pres-
sure loss. As a result, you could lose control of
your vehicle. There is a risk of accident.
Check the tyres regularly for signs of damage
and replace any damaged tyres immediately.
M+S tyres
G
WARNING
M+S tyres with a tyre tread depth of less than
4 mm are not suitable for use in winter as they
do not provide sufficient traction. There is a
risk of accident.
M+S tyres with a tread depth of less than
4 mm must be replaced.
G
WARNING
The wheel or tyre size as well as the tyre type
of the spare wheel and the wheel to be
replaced may differ. Driving characteristics
can be severely impaired when you fit the
spare wheel. There is a risk of an accident.
To prevent risks:
R
adapt your driving style accordingly and
drive carefully
R
never fit more than one spare wheel that
differs from the wheel to be changed
R
only use a spare wheel that differs from the
wheel to be changed for a brief period
R
do not switch ESP
®
off
R
have a spare wheel of a different size
replaced at the nearest qualified specialist
workshop. You must make sure that the
wheel and tyre dimensions as well as the
tyre type are correct.
Do not exceed a maximum speed of 80 km/h if
a spare wheel of a different size is fitted.
At temperatures below +7 †, use winter tyres or
all-season tyres. Both types of tyre are identified
by the M+S marking.
Only winter tyres bearing the
i
snowflake
symbol in addition to the M+S marking provide
the best possible grip in wintry road conditions.
Only these tyres will allow driving safety sys-
tems such as ABS and ESP
®
to function opti-
mally in winter. These tyres have been devel-
oped specifically for driving in snow.
Use M+S tyres of the same make and tread on all
wheels to maintain safe handling characteris-
tics.
Always observe the maximum permissible
speed specified for the M+S tyres you have fit-
ted.
If you fit M+S tyres that have a lower maximum
permissible speed than that of the vehicle, affix
an appropriate warning label in the driver's field
of vision. This can be obtained at a qualified
specialist workshop.
When you have fitted the M+S tyres:
X
Check the tyre pressures (
Y
page 238).
X
Restart the tyre pressure monitor
(
Y
page 241).
Snow chains
G
WARNING
If you drive too fast with snow chains fitted,
they may snap. As a result, you could injure
others and damage the vehicle. There is a risk
of an accident.
Observe the maximum permissible speed for
operation with snow chains.
!
Before fitting the snow chains, check them
for damage. Damaged or worn snow chains
may snap and damage the following compo-
nents:
