responsibility to maintain correct
tyre pressure, even if under-inflation
has not reached the level to trigger
illumination of the TPMS low tyre
pressure telltale.
Your vehicle has also been
equipped with a TPMS malfunction
indicator to indicate when the
system is not operating properly.
The TPMS malfunction indicator is
combined with the low tyre pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately one minute and then
remain continuously illuminated.
This sequence will continue upon
subsequent vehicle start-ups as
long as the malfunction exists.
When the malfunction indicator is
illuminated, the system may not be
able to detect or signal low tyre
pressure as intended. TPMS
malfunctions may occur for a variety
of reasons, including the installation
of replacement or alternate tyres or
wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more
tyres or wheels on your vehicle to
ensure that the replacement or
alternate tyres and wheels allow the
TPMS to continue to function
properly.

Tyre Pressure Monitor

Operation

This vehicle may have a Tyre
Pressure Monitor System (TPMS).
The TPMS is designed to warn the
driver when a low tyre pressure
condition exists. TPMS sensors are
mounted onto each tyre and wheel
assembly, excluding the spare tyre
and wheel assembly. The TPMS
sensors monitor the air pressure in
the tyres and transmits the tyre
pressure readings to a receiver
located in the vehicle.
When a low tyre pressure condition
is detected, the TPMS illuminates
the low tyre pressure warning light
on the instrument cluster. If the
warning light comes on, stop as
soon as possible and inflate the
tyres to the recommended pressure
shown on the Tyre and Loading
Information label. See Vehicle Load
Limits on page 9-10.
A message to check the pressure in
a specific tyre displays in the Driver
Information Centre (DIC). The low
tyre pressure warning light and the
DIC warning message come on at
each ignition cycle until the tyres
are inflated to the correct inflation
pressure. Using the DIC, tyre
pressure levels can be viewed. For
