damage can be de tected, ha vethe tyres and
wheels checked at a qualified specialist work‐

WARNING Risk of injury duetodamaged
tyres
Damaged tyres can cause tyre pressure loss. #
Check the tyres regularly for signs of
dama geand replace any damaged tyres
immediatel y. Check
the wheels and tyres of your vehicle for
damage regular ly, i.e. at least every two weeks,
as well as af ter driving off-road or on rough

ex ample:
R cuts in the tyres
R punctures in the tyres
R tears in the tyres
R bulges on tyres
R deformation or se vere cor rosion on wheels &
WARNING Risk of aquaplaning due to
insuf ficient tyre tread
Insu fficient tyre tread will result in reduced
tyre grip.
The risk of aquaplaning is increased on wet
ro ads, especially when the speed of theve hi‐
cle is not adap tedto suit the conditions. #
Thus, you should regularly check the
tread de pth and the condition of the
tread across the entire width of all
tyres. Minimum tread dep
thfor:
R Summer tyres: 3 mm
R M+S tyres: 4 mm #
For saf etyre asons, replace the tyres
before the legally-prescribed limit for
th e minimum tread dep thisreached. Conduct
thefo llowing checks regular lyon all
wheels, at least once a month or as requ ired, e.g.
before a long journey or when driving off-ro ad:
R check the tyre pressure (/ page 250)
R check theva lve caps

The minimum tread dep thfor summer tyres is
3 mm and for winter tyres 4 mm. Information on driving with summer tyres
At temp eratures below 10°C summer tyres lose
elasticity and therefore traction and braking
po we r.Chan gethe tyres on your vehicle toM+S
tyres. Using summer tyres at very cold temp era‐
tures could cause tears toform ,th ereby damag‐

Once you ha vefitted the summer tyres:
R Check the tyre pressures (/ page 250)
R Restart the tyre pressure monitor
(/ page 255) Information on M+S tyres
At temp eratures below 10°C use winter tyres or
all-season tyres – bo thare mar ked with M+S.
Only winter tyres bearing the004D snowflake
symbol in addition tothe M+S marking pr ovide
th e best possible grip in wintry road conditions.
On lythese tyres will allow driving saf ety sy stems
such as ABS and ESP ®
to also function optimally
in winter. These tyres ha vebeen de veloped spe‐
cifically for driving in sno w.
Use M+S tyres of the same make and tread on all
wheels tomaintain safe handling characteristics.
