Seasonal temperature changes will affect tire pressure,

and the TPMS will monitor the actual tire pressure in the

tire.

Base System

The Tire Pressure Monitor System (TPMS) uses wireless

technology with wheel rim-mounted electronic sensors to

monitor tire pressure levels. Sensors, mounted to each

wheel as part of the valve stem, transmit tire pressure

readings to the Receiver Module.

NOTE:

It is particularly important for you to check the tire

pressure in all of your tires regularly and to maintain the

proper pressure.
The Tire Pressure Monitor System (TPMS) consists of the

following components:

Receiver Module

Four Tire Pressure Monitoring Sensors

Tire Pressure Monitoring System Warning Light

A tire pressure monitoring sensor is located in the spare

wheel if the vehicle is equipped with a matching full size

spare wheel and tire assembly. The matching full size spare

tire can be used in place of any of the four road tires. A low

spare tire will not cause the TPMS Warning Light to

illuminate or the chime to sound while stowed in the spare

location.

The TPMS Warning Light will illuminate in the

instrument cluster, a “LOW TIRE PRESSURE”

message will display in the instrument cluster,

and an audible chime will be activated when one

or more of the four active road tire pressures are low.

Should this occur, you should stop as soon as possible,

check the inflation pressure of each tire on your vehicle,

and inflate each tire to the vehicle’s recommended cold

placard pressure value. The system will automatically

update and the TPMS Warning Light will extinguish once

the updated tire pressures have been received. The vehicle

may need to be driven for up to 20 minutes above 15 mph

(24 km/h) to receive this information.
