When a low tire pressure condition is detected, the
TPMS displays the CHECK TIRE PRESSURE warning
message on the DIC, and at the same time illuminates
the low tire pressure warning symbol. For additional
information and details about the DIC operation
and displays see DIC Operation and Displays on
page 3-50 and DIC Warnings and Messages on
page 3-54.
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 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.
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 CHECK TIRE PRESSURE warning message and
low tire pressure light (telltale) will appear at each
ignition cycle until the tires are inflated to the correct
inflation pressure.
