When a low tire pressure condition is detected,
the TPMS illuminates the low tire pressure warning
light, located in the instrument panel cluster,
and at the same time the LOW TIRE PRESSURE
warning message on the Driver Information
Center (DIC) displays. The low tire pressure
warning light and the DIC warning message
appear at each ignition cycle until the tires are
inflated to the correct inflation pressure. For
additional information and details about the DIC
operation and displays see DIC Controls and
Displays on page 204 and DIC Warnings
and Messages on page 206.
You may notice, during cooler weather conditions,
that the low tire pressure warning light and the
LOW TIRE PRESSURE DIC warning message
may come on when the vehicle is first started, and
then turn off as you start to drive. This may be
an early indicator that the air pressure in the tire(s)
is getting low and needs to be inflated to the
proper pressure.
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 tire failure. Under-inflation also
reduces fuel efficiency and tire tread life, and may
affect the vehicle’s handling and stopping ability.
