Tyre pressure monitoring

Updated 05/15/2024

Your car can detect and indicate if the tyre pressure is too low. Tyre pressure monitoring cannot be disabled. If the system is unable to detect low tyre pressure, it will indicate that there's a malfunction.

The tyre pressure monitoring system can only provide updated information after you have driven the car above 30 km/h (20 mph) for several minutes.

An indicator symbol lights up if a low tyre pressure is detected in any of the tyres. It will stay illuminated until the problem is resolved.

In addition to messages in the display, you can also find information about the tyre pressure monitoring in the car status view.

Warning

No advance warning possible

The system cannot give you any advance warning of potential tyre damage.

Ensure correct tyre pressure immediately

When the low tyre pressure symbol is lit, stop and check the tyre pressures as soon as possible. Driving with underinflated tyres can cause tyre failure.

If you experience a malfunction or a fault is permanently indicated for the tyre pressure monitoring system, a service is required.1

Remember:

The system does not replace the need for regular tyre inspection and maintenance.
The indication symbol for low tyre pressure won't disappear until the low tyre pressure has been corrected.

Note

Tyre pressure monitoring sensors need to be mounted on all wheels, including winter tyres. If you use a spare wheel or other wheel without the sensor, a fault message will appear in the driver information area after a few minutes of driving. Remember to make sure that new wheels have the sensor to avoid a system malfunction warning.

System description

The following information is phrased according to external legal requirements.

Each tyre, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tyre inflation pressure label. (If your vehicle has tyres of a different size than the size indicated on the vehicle placard or tyre inflation pressure label, you should determine the proper tyre inflation pressure for those tyres.)

As an added safety feature, your vehicle has been equipped with a tyre pressure monitoring system (TPMS) that illuminates a low tyre pressure telltale when one or more of your tyres is significantly under-inflated. Accordingly, when the low tyre pressure telltale illuminates, you should stop and check your tyres as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated tyre causes the tyre to overheat and can lead to tyre failure. Under-inflation also reduces fuel efficiency and tyre tread life, and may affect the vehicle's handling and stopping ability.

Please note that the TPMS is not a substitute for proper tyre maintenance, and it is the driver's responsibility to maintain correct tyre pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low tyre pressure telltale.

Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tyre pressure telltale. When the system detects a malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction indicator is illuminated, the system may not be able to detect or signal low tyre pressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tyres or wheels on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after replacing one or more tyres or wheels on your vehicle to ensure that the replacement or alternate tyres and wheels allow the TPMS to continue to function properly.
