Tire Pressure Monitor
Operation
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS is designed to warn
the driver when a low tire pressure
condition exists. TPMS sensors
are mounted onto each tire and
wheel assembly on the vehicle,
excluding the spare tire. The TPMS
sensors monitor the air pressure
in the vehicle’s tires and transmit the
tire pressure readings to a receiver
located in the vehicle.
When a low tire pressure condition
is detected, the TPMS illuminates
the low tire pressure warning light
located on the instrument panel
cluster.
At the same time, a Driver
Information Center (DIC) message
is displayed on the DIC display
screen. The low tire pressure
warning light and the DIC warning
message come on 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 3-34 and DIC
Warnings and Messages on
page 3-37.
The low 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 air pressure in the tire(s) are
getting low and need to be inflated
to the proper pressure.
A Tire and Loading Information
label, attached to the vehicle, shows
the size of the vehicle’s original
equipment tires and the correct
inflation pressure for the vehicle’s
tires when they are cold. See
Loading the Vehicle on page 4-35,
for an example of the Tire and
Loading Information label and its
location on the vehicle. Also see
Inflation - Tire Pressure on
page 5-51.
The vehicle’s TPMS can warn you
about a low tire pressure condition
but it does not replace normal
tire maintenance. See Tire
Inspection and Rotation on
page 5-57 and Tires on page 5-44.
Notice: Liquid tire sealants
could damage the Tire Pressure
Monitor System (TPMS) sensors.
Sensor damage caused by using
a tire sealant is not covered
by your warranty. Do not use
liquid tire sealants.
