WARNING Risk of accident caused by
incorrect wheel and tire dimensions
The wheel or tire sizes and the tire type of the
emergency spare wheel or spare wheel and
the wheel to be replaced may differ. The emer-
gency spare wheel or spare wheel can signifi-
cantly impair driving characteristics of the
vehicle.
To prevent hazardous situations:
#
Drive carefully.
#
Never install more than one emergency
spare wheel or spare wheel that differs
in size.
#
Only use an emergency spare wheel or
spare wheel briefly.
#
Do not deactivate ESP
®
.
#
Have the emergency spare wheel or
spare wheel of a different size replaced
at the nearest qualified specialist work-
shop. The new wheel must have the cor-
rect dimensions.
The collapsible spare wheel is an emergency
spare wheel which is only suitable for use for a
limited period of time and in a restricted manner
in the event of a flat tire (e.g. until the nearest
workshop).
The tire sidewalls are folded when in transport
mode. Before use, the collapsible spare wheel has
to be inflated with the accompanying compressor.
Check the tire pressure of the collapsible spare
wheel once mounted. Correct the pressure as
necessary.
The maximum permissible speed with a collapsi-
ble spare wheel mounted is 50 mph (80 km/h).
Do not mount the collapsible spare wheel with
snow chains.
Replace the collapsible spare wheel after six years
at the latest, regardless of wear.
%
Vehicles with a tire pressure monitoring sys-
tem: if a collapsible spare wheel is mounted,
the tire pressure monitoring system cannot
function reliably. For a few minutes after an
emergency spare wheel is mounted, the sys-
tem may still display the tire pressure of the
removed wheel. Only restart the system again
when the collapsible spare wheel has been
replaced with a new wheel.
