Tire Pressure Monitoring System, Direct System

Tire Pressure Monitoring System, Direct System

Observe notes about usage in your owner's manual.

The Tire Pressure Monitoring System monitors tire pressure as well as temperature when driving.

For passenger safety, always replace any damaged tire pressure sensors or valves.

Do not clean the tire pressure sensor with steam jet cleaners or strong compressed air.

For safety reasons, the tire pressure monitoring sensor should be replaced and the rim cleaned after using tire sealant.

There is a Base Version (Low) or Comfort Version (High)

The Low version consist of a control module, a central antenna and a tire pressure sensor in each wheel.

The High version also has a trigger in each wheel housing and also recognizes the positions of the installed sensors.

Version installed is indicated by corresponding PR number on vehicle data plate. Refer to => [ Production Control Number (PR Number), Explanations ] Application and ID.

If wheel positions are changed on vehicle, wheels changed, the tire pressure sensors replaced or pressures changed, this must be confirmed in the MMI.

If conventional wheels (e.g. winter tires without run-flat capability) are installed in place of the Pax system, the system must be re-coded via Guided Fault Finding using the function "Code control module".

• Check the tire pressures and then adapt the tire pressure sensors using the MMI whenever changing a wheel with the tire pressure sensor (summer/winter tires).

A fault may be saved in the DTC memory if:

When installing less than four wheels with tire pressure sensors.

When installing winter tires without or with incorrect tire pressure sensors. (If this is the case, the yellow warning lamp in instrument cluster "system malfunction diagram" is set and cannot be deactivated by the system).
