When Driving
Tyre Pressure Monitoring System
Tyre Pressure Monitoring System (Vehicle with Run- at
*
Tyres)
The Tyre Pressure Monitoring System (TPMS) monitors the pressure for each tyre.
If tyre pressure is too low in one or more tyres, the system will inform the driver via the
warning light in the instrument cluster and by the warning beep sound.
Refer to Warning Indication/Warning Lights on page 4-42 .
Refer to Tyre In ation Pressure Warning Beep on page 7-53 .
The tyre pressure sensors installed on each wheel send tyre pressure data by radio signal to
the receiver unit in the vehicle.

NOTE
When the ambient temperature is low due to seasonal changes, tyre temperatures are also
lower. When the tyre temperature decreases, the air pressure decreases as well. The TPMS
warning light may illuminate more frequently. Visually inspect the tyres daily before
driving, and check tyre pressures monthly with a tyre pressure gauge. When checking tyre
pressures, use of a digital tyre pressure gauge is recommended.
TPMS does not alleviate your need to check the pressure and condition of all four tyres
regularly.
