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 transmit 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
located on the instrument cluster.
If the warning light comes on, stop
as soon as possible and inflate the
tires to the recommended pressure
shown on the Tire and Loading
Information label. See Vehicle Load
Limits on page 9 9.
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
additional information and details
about the DIC operation and
displays see Driver Information
Centre (DIC) on page 5 23.
The low tyre pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
could be an early indicator that the
air pressure is getting low and
needs to be inflated to the proper
pressure.
A Tyre and Loading Information
label, attached to your vehicle,
shows the size of the original
equipment tyres and the correct
inflation pressure for the tyres when
they are cold. See Vehicle Load
Limits on page 9 9, for an example
of the Tyre and Loading Information
label and its location. Also see Tyre
Pressure on page 10 38.
The TPMS can warn about a low
tyre pressure condition but it does
