Tire pressure monitoring system
Features and controls 5-87
5
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 the vehicle placard or tire inflation pressure label. (If your vehicle has tires of a different sizethan the size indicated on the vehicle placard or tire inflation pressure label, you should determine the proper tire inflation pressurefor those tires.) As an added safety feature, your vehicle has been equipped with a tire pressure monitoringsystem (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 tell-tale illuminates, you should stop and check your tires as soon as possible, and inflate them to the proper pres
sure. 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 forproper tire maintenance, and it is the driver’s responsibility to maintain correct tire pres- sure, even if under-inflation has not reachedthe level to trigger illumination of the TPMS low tire pressure telltale. Your vehicle has also been equipped with aTPMS malfunction indicator to indicate whenthe 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 min- ute 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 illumi- nated, 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 alternat
e 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 moretires 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 hard braking, sharp steering maneuvers andhigh speeds. You should stop and adjustthe tires to the proper inflation pressure as soon as possible. Adjust the spare tire at the same time. Refer to “Tires” on page9-12.
NOTE
In addition, the warning display is displayed on the information screen in the multi-infor- mation display.
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 thevalve 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 could get 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 corrosionand damage of the tire inflation pressure sen- sors.
