Tire pressure monitoring system 5-102 Features and controls

Ty p e 1 Ty p e 2 Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure recom- mended by the vehicle manufacturer on thevehicle placard or tire inflation pressure label. (If your vehicle has tires of a different size than the size indicated on the vehicle placardor tire inflation pressure label, you shoulddetermine the proper tire inflation pressure for those tires.) As an added safety feature, your vehicle hasbeen equipped with a tire pressure monitoring system (TPMS) that illuminates a low tire pressure telltale when one or more of yourtires is significantly under-inflated. Accordingly, when the low tire pressure tell- tale illuminates, you should stop and checkyour tires as soon as possible, and inflate them to the proper pressure. Driving on a sig-
nificantly 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 vehi-cle’s handling and stopping ability. Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver’sresponsibility to maintain correct tire pres- sure, even if under-inflation has not reached the level to trigger illumination of the TPMSlow tire pressure telltale.Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. TheTPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a malfunction, thetelltale will flash for approximately one min- ute and then remain continuously illuminated. This sequence will continue upon subsequentvehicle start-ups as long as the malfunction exists. When the malfunction indicator is illumi-nated, the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a varietyof reasons, including the installation of replacement or alternate tires or wheels on the vehicle that prevent the TPMS from function-ing properly. Always check the TPMS mal- function 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 prop- erly.

1. If the tire pressure monitoring system warning light illuminates, avoid hardbraking, sharp steering maneuvers andhigh speeds. You should stop and adjust the tires to the proper inflation pressure as soon as possible. Adjust the spare tire atthe same time. Refer to “Tires” on page 9-17.
If the warning light/display illu- minates while driving
NOTE
In addition, the warning display is displayed on the information screen in the multi-infor- mation display. When inspecting or adjusting the tire pres- sure, do not apply excessive force to the valve stem to avoid breakage. After inspecting or adjusting the tire pres- sure, always reinstall the valve cap on the valve stem. Without the valve cap, dirt or moisture couldget into the valve, resulting in damage to the tire inflation pressure sensor. Do not use metal valve caps, which may cause a metal reaction, resulting in corrosion and damage of the tire inflation pressure sen-sors.
