CAUTION!
Aftermarket wheels can cause sensor
damage.
• Using aftermarket tire sealants may
cause the Tire Pressure Monitoring Sys-
tem (TPMS) sensor to become inoper-
able. After using an aftermarket tire
sealant it is recommended that you take
your vehicle to an authorized dealership
to have your sensor function checked.
• After inspecting or adjusting the tire
pressure always reinstall the valve stem
cap. This will prevent moisture and dirt
from entering the valve stem, which
could damage the TPMS sensor.
NOTE:
• The TPMS is not intended to replace nor-
mal tire care and maintenance or to provide
warning of a tire failure or condition.
• The TPMS should not be used as a tire
pressure 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 efficiency 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 respon-
sibility to maintain correct tire pressure
using an accurate tire pressure gauge, even
if under-inflation has not reached the level
to trigger illumination of the TPMS 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 indica-
tor located in the instrument
cluster.
The TPMS uses wireless technology with
wheel rim mounted electronic sensors to
monitor tire pressure levels.
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 regularly and to maintain the proper
pressure.
The TPMS consists of the following compo-
nents:
• Receiver Module.
• Four Tire Pressure Monitoring Sensors.
• Tire Pressure Monitoring System Warning
Light.
Tire Pressure Monitoring Low Pressure
Warnings
The Tire Pressure Monitoring System Warning
Light will illuminate in the instrument clus-

the "Check tire pressure" text message will
display when one or more of the four active
