The TPMS is designed to alert the driver, if a low
tire pressure condition exists. If your vehicle has
the Driver Information Center (DIC), the driver may
also check tire pressure levels using the DIC.
When a low tire pressure condition is detected,
the TPMS will illuminate the low tire pressure
warning symbol located on the instrument panel
cluster. If your vehicle has the DIC feature, a
message to check the pressure in a specific tire
will also appear on the DIC display. The low tire
pressure warning symbol on the instrument panel
cluster and the CHECK TIRE PRESSURE warning
message on the DIC display will 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 Operation and Displays on page 240 and
DIC Warnings and Messages on page 245.
You may notice, during cooler weather conditions,
that the tire pressure monitor light, located on
the instrument panel cluster, and the CHECK
TIRE PRESSURE message will appear when the
vehicle is first started and then turn off as you
start to drive the vehicle. This could be an early
indicator that the tire pressures are getting low
and need 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.
