Tire Location

CAUTION: Take care when you remove and refit tires to ensure that the tire pressure sensor is not damaged.

Because of the requirement for different pressure targets and thresholds for the front and rear tires, the Tire Pressure Monitoring System (TPMS) can identify the location of the sensors on the vehicle, and assign received tire pressure sensor identification to a specific position on the vehicle, that is to say, front left, front right, rear left or rear right.

The TPMS does the tire sensor location automatically using an auto-location function. This function does not need any manual intervention by the driver. The TPMS can automatically learn the position of tire sensors on the vehicle if the tire pressure sensors or their positions are changed on the vehicle.

The tire-learn and location process is ready to start when the vehicle has been stationary or is traveling at less than 20 km/h (12.5 mph) for 15 minutes. This is known as Parking mode. The learn/locate process needs the vehicle to be driven at speeds of more than 20 km/h (12.5 mph) for 10 minutes. If the vehicle speed reduces to below 20 km/h (12.5 mph), the learn process timer is suspended until the vehicle speed increases to more than 20 km/h (12.5 mph), after which time the timer is resumed. If the vehicle speed stays below 20 km/h (12.5 mph) for more than 15 minutes, the timer is set to zero and the process starts again.

The TPMS can automatically detect, under all operating conditions, the following:

One or more tire pressure sensors have been replaced.
One or more tire pressure sensor identifications are missing.
One or more tire pressure sensors have stopped transmitting.
Identifications from tire pressure sensors which do not belong to the vehicle.
One or more of the wheels in use on the vehicle has changed position.
One or more incompatible tire pressure sensors have been fitted.
A full-sized spare wheel is swapped with a running wheel.

NOTE: The spare wheel sensor ID must be written into the Tire Pressure Monitoring System Control Module (TPMSCM) by diagnostics and cannot be learned automatically.

If the tire pressure sensors fitted to the running wheels are changed, the TPMS can learn the new sensor identifications automatically. The learn function requires no manual intervention by the driver.

NOTE: You must service the TPMS valve using the appropriate service kit each time you dismount the tire, to ensure an airtight seal. Follow the instructions about using this kit.
