Check Tire Pressure Soon * Canada only: The tire pressure loss warning system has detected a significant loss in pressure.
WARNING Risk of an accident due to insufficient tire pressure
Tire pressures that are too low pose the following hazards:
  • The tires may burst, especially as the load and vehicle speed increase.
  • The tires may wear excessively and/or unevenly, which may greatly impair tire traction.
  • The driving characteristics, as well as steering and braking, may be greatly impaired.

You could then lose control of the vehicle.

  • Observe the recommended tire pressure.
  • Adjust the tire pressure if necessary.
  • Stop the vehicle, paying attention to road and traffic conditions.
  • Check the tire pressure and the tires.
  • When the tire pressure is correct, restart the tire pressure loss warning system

Warning Tire Malfunction

* The tire pressure in one or more tires has dropped suddenly. The wheel position is displayed.
WARNING Risk of an accident from driving with a flat tire
Flat tires are dangerous in the following ways:
  • The tires can overheat and cause a fire.
  • The driving characteristics, as well as steering and braking, may be greatly impaired.

You could then lose control of the vehicle.

  • Do not drive with a flat tire.
  • Observe the notes on flat tires.

Notes on flat tire.

  • Adjust the tire pressure if necessary.
  • Stop the vehicle, paying attention to road and traffic conditions.
  • Check the tire pressure and the tires.

Please Correct Tire Pressure

* The tire pressure is too low in at least one of the tires, or the tire pressure difference between the wheels is too great.
  • Check the tire pressure and add air, if necessary.
  • When the tire pressure is correct, restart the tire pressure monitoring system.

Tire Press. Monitor Currently Unavailable

* There is interference from a powerful radio signal source. As a result, no signals from the tire pressure sensor are received. The tire pressure monitoring system is temporarily unavailable.
  • Drive on.

    The tire pressure monitoring system restarts automatically as soon as the cause has been rectified.

Wheel Sensor(s) Missing

* The tire pressure sensor signal is missing from one or more tire(s). The pressure of the affected tire is not displayed.
  • Have the defective tire pressure sensor replaced at a qualified specialist workshop.

Tire Pressure Monitor Inoperative No Wheel Sensors

* The wheels installed do not have suitable tire pressure sensors. The tire pressure monitoring system is deactivated.
  • Install wheels with suitable tire pressure sensors.

Tire Press. Monitor Inoperative

* The tire pressure monitoring system is defective.
WARNING There is a risk of an accident if the tire pressure monitoring system is malfunctioning
If the tire pressure monitoring system is malfunctioning, it is not able to issue a warning if there is pressure loss in one or more of the tires.

Underinflated tires may, for example, impair the driving, steering and braking characteristics.

  • Have the tire pressure monitoring system checked at a qualified specialist workshop.
  • Visit a qualified specialist workshop.
Tires Overheated * At least one tire is overheating. The affected tires are displayed in red. At temperatures close to the limit value, the tires are displayed in yellow.
