Your vehicle has also been equipped with a TPMS

malfunction indicator to indicate when the system is not

operating properly. The TPMS malfunction indicator is

combined with the low tire pressure telltale. When the

system detects a malfunction, the telltale will flash for

approximately one minute and then remain continuously

illuminated. This sequence will continue upon subse-

quent vehicle start-ups as long as the malfunction exists.

When the malfunction indicator is illuminated, the sys-

tem may not be able to detect or signal low tire pressure

as intended. TPMS malfunctions may occur for a variety

of reasons, including the installation of replacement or

alternate tires or wheels on the vehicle that prevent the

TPMS from functioning properly. Always check the

TPMS malfunction telltale after replacing one or more

tires or wheels on your vehicle to ensure that the replace-

ment or alternate tires and wheels allow the TPMS to

continue to function properly.

CAUTION!

The TPMS has been optimized for the original

equipment tires and wheels. TPMS pressures and

warning have been established for the tire size

equipped on your vehicle. Undesirable system opera-

tion or sensor damage may result when using re-

placement equipment that is not of the same size,

type, and/or style. Aftermarket wheels can cause

sensor damage. Using aftermarket tire sealants may

cause the Tire Pressure Monitoring System (TPMS)

sensor to become inoperable. After using an after-

market tire sealant it is recommended that you take

your vehicle to an authorized dealership to have your

sensor function checked.

NOTE:

The TPMS telltale is also accompanied by a “Low

Tire” message in the Electronic Vehicle Information Cen-

ter (EVIC). For further information refer to “Tire Pressure

Monitoring System (TPMS) in “Starting And Operating.”
