160 km/h (100 mph) or higher. Set
the cold inflation pressure to
300 kPa (44 psi).
Return the tyres to the
recommended cold tyre inflation
pressure when high-speed driving
has ended. See Vehicle Load Limits

Tyre Pressure Monitor

System

Notice: Modifications made to the
Tyre Pressure Monitor System
(TPMS) by anyone other than an
authorised service facility may
void authorisation to use the
system.
The Tyre Pressure Monitor System
(TPMS) uses radio and sensor
technology to check tyre pressure
levels. The TPMS sensors monitor
the air pressure in your vehicle's
tyres and transmit tyre pressure
readings to a receiver located in the
vehicle.
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.
Please note that the TPMS is not a
substitute for proper tyre
maintenance, and it is the driver's
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
