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.
