272 SAFETY
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. Underinflation 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 responsi-
bility to maintain correct tire pressure using
an accurate tire gauge, even if underinflation
has not reached the level to trigger illumina-
tion of the TPMS Warning Light.
Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor the
actual tire pressure in the tire.
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.
Tire Pressure Monitoring Display
NOTE:
It is particularly important for you to regularly
check the tire pressure in all of your tires and to
maintain the proper pressure Ú page 395.
The Tire Pressure Monitoring System (TPMS)
consists of the following components:
Receiver Module
Four Tire Pressure Monitoring System
sensors
Various Tire Pressure Monitoring System
Messages, which display in the instrument
cluster, and a graphic displaying tire pres-
sures
TPMS Warning Light
CAUTION!
The TPMS has been optimized for the orig-
inal equipment tires and wheels. TPMS pres-
sures and warnings have been established
for the tire size equipped on your vehicle.
Undesirable system operation or sensor
damage may result when using replacement
equipment that is not of the same size, type,
and/or style. The TPM sensor is not
designed for use on aftermarket wheels and
may contribute to a poor overall system
performance or sensor damage. Customers
are encouraged to use OEM wheels to
assure proper TPM feature operation.
Using aftermarket tire sealants may cause
the Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. 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 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.
