For additional information and details about the DIC operation and displays see DIC Operation and Displays on page 3-45 and DIC Warnings and Messages on page 3-52. 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 Your Vehicle on page 4-20, for an example of the Tire and Loading Information label and its location on your vehicle. Also see Inflation - Tire Pressure on page 5-64. 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 5-71 and Tires on page 5-56. 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. TPMS Malfunction Light and Message The TPMS will not function properly if one or more of the TPMS sensors are missing or inoperable. When the system detects a malfunction, the low tire warning light flashes for about one minute and then stays on for the remainder of the ignition cycle. A DIC warning message is also displayed. The low tire warning light and DIC warning message come on at each ignition cycle until the problem is corrected. Some of the conditions that can cause the malfunction light and DIC message to come on are: • One of the road tires has been replaced with the spare tire. The spare tire does not have a TPMS sensor. The TPMS malfunction light and DIC message should go off once you re-install the road tire containing the TPMS sensor. • The TPMS sensor matching process was started but not completed or not completed successfully after rotating the vehicle's tires. The DIC message and TPMS malfunction light should go off once the TPMS sensor matching process is performed successfully. See "TPMS Sensor Matching Process" later in this section. 5-68

DIC Warnings and Messages on

page 3-52

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 Your

Vehicle on page 4-20

, for an example of the Tire and

Loading Information label and its location on your vehicle.

Also see

Inflation - Tire Pressure on page 5-64

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 5-71

and

Tires on page 5-56

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.

TPMS Malfunction Light and Message

The TPMS will not function properly if one or more of the

TPMS sensors are missing or inoperable. When the

system detects a malfunction, the low tire warning light

flashes for about one minute and then stays on for

the remainder of the ignition cycle. A DIC warning

message is also displayed. The low tire warning light

and DIC warning message come on at each ignition

cycle until the problem is corrected. Some of the

conditions that can cause the malfunction light and DIC

message to come on are:

•

One of the road tires has been replaced with the

spare tire. The spare tire does not have a TPMS

sensor. The TPMS malfunction light and DIC

message should go off once you re-install the road

tire containing the TPMS sensor.

•

The TPMS sensor matching process was started

but not completed or not completed successfully

after rotating the vehicle’s tires. The DIC message

and TPMS malfunction light should go off once

the TPMS sensor matching process is performed

successfully. See “TPMS Sensor Matching Process”

later in this section.
