Emergency spare wheel
462
An emergency spare wheel may also be fitted
against the direction of rotation. Observe the
time restriction on use as well as the speed
limitation specified on the emergency spare
wheel.
Replace the tyres after six years at the latest,
regardless of wear. This also applies to the
emergency spare wheel.
If you are driving with the collapsible emer-
gency spare wheel fitted, the tyre pressure
loss warning system or the tyre pressure
monitor cannot function reliably. Only restart
the tyre pressure loss warning system/tyre
pressure monitor when the defective wheel
has been replaced with a new wheel.
Vehicles with tyre pressure monitor: after
mounting an emergency spare wheel, the sys-
tem may still display the tyre pressure of the
removed wheel for a few minutes. The value
displayed for the mounted emergency spare
wheel is not the same as the current tyre
pressure of the emergency spare wheel.
If you are driving with the emergency spare
wheel fitted, the tyre pressure loss warning
system cannot function reliably. Only restart
the tyre pressure loss warning system when
the defective wheel has been replaced with a
new wheel.
