Status display

The tire and system status is indicated by the color of the tires.

A change in the tire inflation pressure during driving is taken into account.

A correction is only necessary if this is indicated by the TPM

Wheels, green

The tire inflation pressure is equal to the target state.

One wheel is yellow

A flat tire or major drop in inflation pressure in the indicated tire.

All wheels are yellow

  • A flat tire or major drop in inflation pressure in several tires.
  • The system was not reset after a wheel change and thus warns based on the inflation pressures initialized last.
  • A flat tire in one or more tires while the system is being reset.

Wheels, gray

The system cannot detect a flat tire. Reasons for this may be:

  • TPM is being reset.
  • Disturbance by systems or devices with the same radio frequency.
  • Malfunction.

For Canadian models: additional information

The status display additionally shows the current tire inflation pressures and tire temperatures.

When correcting the tire inflation pressures, note the following:

The tire pressure increases as the tire temperature increases.

Therefore, only correct the tire inflation pressure when the tire is at the ambient temperature. Compare the displayed tire temperature with the external temperature in the instrument cluster.
