TIRE PRESSURE MONITORING SYSTEM

WARNING:

The tire pressure monitoring system is NOT a

substitute for manually checking tire pressure. The tire pressure

should be checked periodically (at least monthly) using a tire gauge. See

Inflating Your Tires in this chapter. Failure to properly maintain your tire

pressure could increase the risk of tire failure, loss of control, vehicle

rollover and personal injury.

Each tire, including the spare (if provided), should be checked

monthly when cold and inflated to the inflation pressure

recommended by the vehicle manufacturer on the vehicle placard

or tire inflation pressure label. (If your vehicle has tires of a different size

than the size indicated on the vehicle placard or tire inflation pressure label,

you should determine the proper tire inflation pressure for those tires.)

As an added safety feature, your vehicle has been equipped with a tire

pressure monitoring system (TPMS) that illuminates a low tire pressure

telltale when one or more of your tires is significantly under-inflated.

Accordingly, when the low tire pressure telltale illuminates, you should stop

and check your tires as soon as possible, and inflate them to the proper

pressure. 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.

Please note that the TPMS is not a substitute for proper tire

maintenance, and it is the driver’s responsibility to maintain correct tire

pressure, even if under-inflation has not reached the level to trigger

illumination of the TPMS low tire pressure telltale.

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

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

When the malfunction indicator is illuminated, the system 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 replacement or alternate tires and wheels allow the

TPMS to continue to function properly.
