Tire Pressure Monitoring System (TPMS)
The purpose of the Tire Pressure Monitoring System (TPMS) is to help the driver to keep the vehicle's tire pressures at the optimum level to:
- Improve fuel consumption.
- Maintain ride and handling characteristics.
- Reduce the risk of rapid tire deflation, which may be caused by under-inflated tires.
- Comply with legislation in relevant markets.
The TPMS measures the pressure in each of the tires on the vehicle and issues warnings to the driver if any of the pressures deviate from defined tolerances.
NOTE:
During a tire 'blow-out' a very rapid reduction in pressure happens. The system is not intended to warn the driver of a 'blow out', as it is not possible to give the driver enough warning that such an event is happening, due to its short duration. The TPMS helps the driver to keep the tires at the correct pressure and this tends to reduce the likelihood of a tire 'blow out' happening. TPMS is inhibited when the vehicle is in Transit mode. For more details on Transit mode, refer to the Pre-Delivery Inspection (PDI) manual.
A single TPMS hardware configuration is used. TPMS status information is relayed to the driver by a message which appears in the Instrument Cluster (IC) message center together with an amber warning indicator.
