ise or unusual handling characteristics
While driving, pay attention tovibrations, noises
and unusual handling characteristics, e.g. pulling
to one side. This may indicate that the wheels or
tyres are damaged. If you suspect that a tyre is
defective, reduce your speed immediatel y.Stop
th eve hicle as soon as possible tocheck the
wheels and tyres for dama ge. Hidden tyre dam‐
age could also be causing the unusual handling

WARNING Risk of accident from dam‐

Dama ged tyres can cause tyre pressure loss.
As a result, you could lose cont rol of your
ve hicle. #
Check the tyres regularly for signs of
dama geand replace any damaged tyres
immediatel y. &
WARNING Risk of aquaplaning due to
insuf ficient tyre tread
Insu fficient tyre tread will result in reduced
tyre grip. The tyre tread is no longer able to
dissipate water.
This means that in heavy rain or slush the
ri sk of aquaplaning is increased, in particular
where speed is not adap tedto suit the condi‐
tions.
If th e tyre pressure is too high or too lo w,
tyres may exhibit dif fere nt le vels of wear at
dif fere nt locations on the tyre tread. #
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. Car
ryout thefo llowing checks on all wheels reg‐
ularly, at least once a month or as requ ired, e.g.
prior toa long journey or driving off- road:
R Check the tyre pressure (→ page 402).
R Visual inspection of wheels and tyres for
damage.
R Check theva lve caps.
The valves must be pr otected against mois‐
