106 SAFETY
CAUTION!
The TPMS has been optimized for the original

equipment tires and wheels. TPMS pressures
and warnings have been established for the
tire size equipped on your vehicle. Undesir-
able system operation or sensor damage may
result when using replacement 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 aftermarket tire sealant it is recom-
mended that you take your vehicle to an
authorized dealership to have your sensor
function checked.
After inspecting or adjusting the tire pres-

sure, always reinstall the valve stem cap. This
will prevent moisture and dirt from entering
the valve stem, which could damage the Tire
Pressure Monitoring Sensor.
NOTE:
The TPMS is not intended to replace normal tire

care and maintenance, or to provide warning of
a tire failure or condition.
The TPMS should not be used as a tire pres-

sure gauge while adjusting your tire pressure.
Driving on a significantly under-inflated tire

causes the tire to overheat and can lead to tire
failure. Under-inflation also reduces fuel effi-
ciency and tire tread life, and may affect the
vehicle's handling and stopping ability.
The TPMS is not a substitute for proper tire

maintenance, and it is the driver's responsi-
bility to maintain correct tire pressure using an
accurate tire gauge, even if under-inflation has
not reached the level to trigger illumination of
the Tire Pressure Monitoring Warning Light.
Seasonal temperature changes will affect tire

pressure, and the TPMS will monitor the actual
tire pressure in the tire.
Base System
This is the TPMS warning indicator
located in the instrument cluster.
The 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 the tires on your vehicle regu-
larly and to maintain the proper pressure.
The TPMS consists of the following components:
Receiver Module

Four Tire Pressure Monitoring sensors

Tire Pressure Monitoring Warning Light.
