Tyre Pressure Monitoring System

Tyre Pressure Monitoring System
The Tyre Pressure Monitoring System (TPMS) monitors the air pressure of all four tyres. If
the air pressure of one or more tyres is too low, the system warns the driver by indicating the
tyre pressure monitoring system warning light in the instrument cluster and operating a beep
sound. The system monitors the tyre pressures indirectly using the data sent from the ABS
wheel speed sensors.
To allow the system to operate correctly, the system needs to be initialized with the specified
tyre pressure (value on the tyre pressure label). Follow the procedure and perform the
initialization.
Refer to Tyre Pressure Monitoring System Initialization on page 4-232.
The warning light flashes when the system has a malfunction.
Refer to Warning Lights on page 4-35.
CAUTION
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.
