drive to the specialist workshop.
R
Do not make any modifications to the brake
system, the wheels or the tyres.
The use of shims or brake dust shields is not
permitted and may invalidate the vehicle's
general operating permit.

Vehicles with a tyre pressure monitoring
system: all fitted wheels must be equipped
with functioning sensors for the tyre pres‐
sure monitoring system.
R
At temperatures below 7 °C use winter tyres
or all-season tyres marked M+S for all
wheels.
Winter tyres bearing the

Observe the maximum permissible speed for
the M+S tyres fitted.
If the tyre's maximum speed is below that of
the vehicle, this must be indicated by an
appropriate label in the driver's field of
vision.
R
Run in new tyres at moderate speeds for the
first 100 km.

and the corresponding driving dynamics.

roadworthiness of the vehicle.
R
ABS, ESP
®
and cruise control operation
are restricted.
This can jeopardise road safety.
