Description And Operation: Operation: Notes

Each time the vehicle is driven, the TPMS learns the locations of the following four wheel-mounted sensors by combining Radio Frequency (RF) transmissions with data from the Anti-lock Brake System (ABS) control module:

Front left
Front right
Rear left
Rear right

NOTE: An ABS fault does not directly cause the TPMS to stop operating. However, if an ABS fault persists, then a TPMS warning may also appear in the IC.

The system enters parking mode after the vehicle speed has been less than 20 km/h (12.5 mph) for 15 minutes. In Parking mode, the tire pressure sensors transmit a coded signal to the TPM module once every 13 hours. If the tire pressure decreases by more than 7 kPa (1 PSI; 0.07 bar), the sensor transmits more often to show that the tire pressure is reducing.

The process of locating the sensors is known as 'Auto Location' and takes up to 10 minutes to complete. During this period, the tire sensors transmit at regular intervals, that is, once every 16 seconds, while the vehicle speed is above 20 km/h (12.5 mph). For the remainder of the drive cycle, the tire sensors transmit once every 64 seconds while the vehicle speed is above 20 km/h (12.5 mph) or, if a change in tire pressure is sensed, until the vehicle stops or the vehicle speed is less than 20 km/h (12.5 mph) for 15 minutes and the system returns to parking mode.

At 25% deflation (or 20% for the EU market), the amber warning indicator in the IC comes on and an appropriate message and/or graphic appears in the Instrument Cluster (IC) message center.

TIRES

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

NOTE: You must service the TPMS valve using the appropriate service kit, each time you dismount the tire, to ensure an air tight seal. Follow the instructions about using this kit.
If the metal valve stem is damaged, you can replace it independently of the tire pressure sensor as it is a separate component so you do not need to replace the entire sensor assembly.

ITEM	DESCRIPTION
1	Tire valve and pressure sensor
2	Tire fitting/removal tool initial start position
3	High tire and bead tension area
4	Low tire and bead tension area

When you remove the tire, you must not use the bead breaker within 90 degrees of the tire valve in each direction.

When you use the tire removal machine, you must position the fitting arm at the start position as shown in the tire changing illustration. You can then rotate the wheel through 180 degrees in a counter-clockwise direction. This relieves the high tension from the tire bead and allows you to manually pull the remaining 180 degrees of the tire from the rim.

When you refit the tire, position the fitting arm as shown. Rotate the tire and take care that the bead on the low tension side of the tire does not damage the sensor.
