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 your
vehicle. The TPMS sensors monitor the air pressure in
the vehicle’s tires and transmits 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 in the instrument
panel cluster.
At the same time a message to check the pressure in
a specific tire appears on the Driver Information Center
(DIC) display. 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.
Using the DIC, tire pressure levels can be viewed by the
driver. 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 3-56.
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
your vehicle, shows the size of your vehicle’s original
equipment tires and the correct inflation pressure for
your vehicle’s tires when they are cold. See Loading the
Vehicle on page 4-23, for an example of the Tire and
Loading Information label and its location on your vehicle.
Also see Inflation - Tire Pressure on page 5-71 for
additional information.
Your 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 5-77, When It Is Time for New Tires on page 5-77,
and Tires on page 5-62.
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.
