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.
