ARNING Risk of aquaplaning due to
insu1cient tyre tread
Insu1cient tyre tread will result in reduced tyre
gr ip.
The risk of aquaplaning is increased on wet
ro ads, especially when the speed of theve hicle
is not adap tedto suit the conditions. #
Thus, you should regular lych 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. 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 o.- road:
R check the tyre pressure (/ page 253)
R check theva lve caps
