WARNING Risk of accident when driving
in run-flat mode
When driving in run-flat mode, the handling
ch aracteristics are impaired. e.g. when cor‐ nering, when accelerating
stronglyand when
braking. #
Do not exceed the maximum permissi‐
ble speed. #
Avoid any abrupt steering and driving
manoeuvres as well as driving over
obs tacles (kerbs, pot holes, off-road).
This applies, in pa rticular, toa loaded
ve hicle. #
Stop driving in run-flat mode if you
notice:
R banging noise
R vehicle vibration
R smoke which smells like rubber
R continuous ESP ®

Check the tyres regularly for signs of
dama geand replace any damaged tyres

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).
