Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses
radio and sensor technology to check tire pressure
levels. TPMS sensors are mounted on each tire
and wheel assembly, except the spare tire.
The TPMS sensors monitor the air pressure in
your vehicle’s tires and transmit tire pressure
readings to a receiver located in the vehicle.
The TPMS is designed to alert the driver if a low
tire pressure condition exists. Tire pressure
levels may also be checked by using the Driver
Information Center (DIC) Trip Information
button, located on the instrument panel. See “Tire
Pressures” underDIC Operation and Displays
on page 195for additional information.
When a low tire pressure condition is detected,
the TPMS will illuminate the low tire pressure
warning symbol located on the instrument panel
cluster, and at the same time a message 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 will appear at each ignitioncycle until the tires are in ated to the correct
in ation pressure. For additional information and
details about the DIC operation and displays
seeDIC Operation and Displays on page 195and
DIC Warnings and Messages on page 199.
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 rst 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 in ated to the proper pressure.
Each tire, including the spare (if provided),
should be checked monthly when cold and in ated
to the in ation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire
in ation pressure label. (If your vehicle has tires
of a different size than the size indicated on
the vehicle placard or tire in ation pressure label,
you should determine the proper tire in ation
pressure for those tires.)
