th MOEx tended tyres (run-0at tyres), you can
continue todrive your vehicle even if there is a
to ta l loss of pressure in one or more tyres. Ho w-
ev er, the tyre a.ected must not show any clear ly
visible damage.
Yo u can recognise MOExtended tyres bythe

WARNING
ARNING Risk of accident from driving
with sealed tyres
A tyre temp orarily sealed with tyre sealant
impairs the handling characteristics and is not
suitable for higher speeds. #
Adapt your driving style accordingly and
drive carefull y. #
Do not exceed the maximum speed limit
with a tyre that has been repaired using
tyre sealant. #

WARNI NG
ARNI NGRisk of aquaplaning due to
insu1cient tyre tread
Insu1cient 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 regula rly ch eck the
tread dep thand the condition of the
tread across the entire width of all tyres.
Minimum tread dep thfor:
R Summer ty res: 3 mm
R M+S tyres: 4 mm #
For saf etyre asons, replace the tyres
before the legall y-prescribed limit forthe
minimum tread dep thisreached. Car
ryout thefo llowing checks on all wheels regu-
lar ly, at least once a month or as required, for
ex ample, prior toa long jou rney or driving o.-
ro ad:
R Check the tyre pressure (/ page 380). R
Visually inspect wheels and tyres for damage.
R Check theva lve caps.
R Visual check of the tyre tread dep thand the
