Tire Pressure Monitor System
The Tire Pressure Monitor (TPM) system uses radio
and sensor technology to check tire pressure levels.
If your vehicle has this feature, sensors are mounted on
each tire and wheel assembly, except the spare tire.
The TPM sensors transmit tire pressure readings
to a receiver located in the vehicle.
When a low tire pressure condition is detected, the
TPM system will display the CHECK TIRE PRESSURE
warning message on the Driver Information Center
(DIC); and at the same time illuminate the low tire
pressure warning symbol. For additional information and
details about the DIC operation and displays see DIC
Operation and Displays on page 3-55 and DIC Warnings
and Messages on page 3-58.
When the tire pressure
monitoring system warning
light is lit, one or more
of your tires is significantly
under-inflated.
You should stop and check your tires as soon as
possible, and inflate them to the proper pressure as
indicated on the vehicle’s tire information placard.
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.
Each tire, including the spare, should be checked monthly
when cold and set to the recommended inflation pressure
as specified in the vehicle placard and owner’s manual.
The Tire and Loading Information label (tire information
placard) shows the size of your vehicle’s original
tires and the correct inflation pressure for your vehicle’s
tires when they are cold. See Inflation - Tire Pressure
on page 5-68. For the location of the tire and loading
information label, see Loading Your Vehicle on
page 4-52.
Your vehicle’s TPM system can alert you about a low
tire pressure condition but it does not replace normal tire
maintenance. See Tire Inspection and Rotation on
page 5-74 and Tires on page 5-61.
Notice: Do not use a tire sealant if your vehicle is
equipped with Tire Pressure Monitors. The liquid
sealant can damage the tire pressure monitor
sensors.
