Tire Pressure Monitor Operation The Tire Pressure Monitor System (TPMS) is designed to warn the driver when a low tire pressure condition exists. TPMS sensors are mounted onto each tire and wheel assembly, excluding the spare tire and wheel assembly. 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 turns on the low tire pressure warning light located on the instrument panel cluster. 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 3-40 and DIC Warnings and Messages on page 3-43. 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 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 Your Vehicle on page 4-27, for an example of the Tire and Loading Information label and its location on your vehicle. Also see Inflation - Tire Pressure on page 5-56. Your vehicle's TPMS system can warn you about a low tire pressure condition but it does not replace normal tire maintenance. See Tire Inspection and Rotation on page 5-63 and Tires on page 5-49. 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 come on at each ignition cycle until the tires are inflated to the 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. 5-59

Tire Pressure Monitor Operation

The Tire Pressure Monitor System (TPMS) is designed

to warn the driver when a low tire pressure condition

exists. TPMS sensors are mounted onto each tire

and wheel assembly, excluding the spare tire and wheel

assembly. 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 turns on the

low tire pressure warning

light located on 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 come on 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 3-40

and

DIC Warnings and Messages on page 3-43

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 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 Your Vehicle on page 4-27

, for an

example of the Tire and Loading Information label and

its location on your vehicle. Also see

Inflation - Tire

Pressure on page 5-56

Your vehicle’s TPMS system can warn you about a low

tire pressure condition but it does not replace normal

tire maintenance. See

Tire Inspection and Rotation

on page 5-63

and

Tires on page 5-49

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.
