If a low tire pressure condition is detected, the
TPMS will display the Check Tire Pressure
message on the DIC or message center and, at
the same time, illuminate the low tire pressure
warning symbol on the instrument panel cluster.
Each tire, 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 tire
inflation pressure label. (If your vehicle has tires
of a different size than the size indicated on
the vehicle placard or tire inflation pressure label,
you should determine the proper tire inflation
pressure for those tires.)
As an added safety
feature, your vehicle
has been equipped
with a tire pressure
monitoring system
(TPMS) that illuminates
a low tire pressure
telltale when one or
more of your tires
is significantly
under-inflated.
Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your tires
as soon as possible, and inflate them to the
proper pressure. Driving on a significantly
under-inflated tire causes the tire to overheat and
can lead to the tire failure. Under-inflation also
reduces fuel efficiency and tire tread life, and may
affect the vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level to
trigger illumination of the TPMS low tire pressure
telltale.
The Tire and Loading Information label shows the
size of your vehicle’s original tires and their
recommended cold inflation pressures. See
Loading Your Vehicle on page 321, for the location
of the tire and loading information label. Also
see Inflation - Tire Pressure on page 402.
The tire pressure warning light may come on in
cool weather when the vehicle is first started, and
then turn off as you start to drive. This could
be an early indicator that the tire pressures are
getting low and need to be inflated to the
proper pressure.
