Mercedes-Benz GLC : Emergency spare wheel / Notes on the emergency spare wheel
WARNING Risk of accident caused by
incorrect wheel and tire dimensions
The wheel or tire size and the tire type of the
emergency spare wheel or spare wheel and
the wheel to be replaced may differ. The
emergency spare wheel or spare wheel can
significantly impair driving characteristics of
the vehicle.
To prevent hazardous situations:
Adapt your driving style
accordingly and
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 of a different size briefly.
Do not switch off ESP®.
Have the emergency spare
wheel or
spare wheel of a different size replaced at the nearest qualified specialist
workshop.
The new wheel must have the
correct dimensions.
The emergency spare wheel is fastened in
the cargo compartment under the cargo
compartment floor.
Observe the following notes on installing an
emergency spare wheel:
- Check the tire pressure of the emergency
spare wheel installed. Correct the pressure
as necessary.
- The maximum permissible speed with an
emergency spare wheel installed is 50 mph
(80 km/h).
- Do not equip the emergency spare wheel
with snow chains.
- Replace the emergency spare wheel after six
years at the latest, regardless of wear.
Vehicles with a tire pressure loss warning
system: If an emergency spare wheel is
installed the tire pressure loss warning system
cannot function reliably. Only restart the system again when the emergency spare
wheel has been replaced with a new wheel.
Vehicles with a tire pressure monitoring
system: If an emergency spare wheel is
installed the tire pressure monitoring system
cannot function reliably. For a few minutes
after an emergency spare wheel is installed,
the system may still display the tire pressure
of the removed wheel. Only restart the system
again when the emergency spare wheel
has been replaced with a new wheel.
