Changing tyre and wheel
size
If tyres of a different size than those
fitted at the factory are used, it may be
necessary to reprogramme the
speedometer as well as the nominal
tyre pressure and make other vehicle
modifications.
After converting to a different tyre
size, have the label with tyre
pressures replaced.
9 Warning
Use of unsuitable tyres or wheels
may lead to accidents and will
invalidate the vehicle type
approval.

Wheel covers

Wheel covers and tyres that are
factory approved for the respective
vehicle and comply with all of the

Use of unsuitable tyres or wheel
covers could lead to sudden
