necessary.
The maximum permissible speed with an
R
emergency spare wheel fitted is 80 km/h.
Do not fit the emergency spare wheel with
R

R

not function reliably. For a few minutes after
an emergency spare wheel is fitted, the sys‐

removed wheel. Only restart the system
again when the emergency spare wheel has
been replaced with a new wheel.
