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 issues a warning 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.
