Mercedes-Benz GLC : Tire pressure / Tire pressure loss warning system

Function of the tire pressure loss warning system

The tire pressure loss warning system warns the driver by means of display messages when there is a severe tire pressure loss.

System limits

The system may be impaired or may not function particularly in the following situations:

• Incorrectly set tire pressure
• Sudden pressure loss caused, for example, by a foreign object penetrating the tire
• Steady pressure loss in several tires

The system has a restricted or delayed function particularly in the following situations:

• Poor ground conditions, e.g. snow or gravel
• Driving with snow chains
• When adopting a very sporty driving style with high cornering speeds or sudden acceleration
• Driving with a very heavy or large trailer
• Driving with a high load

The tire pressure loss warning system is only an aid. It is the driver's responsibility to set the tire pressure to the recommended cold tire pressure suitable for the operating situation and to check it.
