vehicle may cause the tire pressure to rise to approximately
27 psi (186 kPa), but the TPMS Warning Light will still be on.
In this situation, the TPMS Warning Light will turn off only
after the tires are inflated to the vehicle's recommended cold
placard pressure value.
CAUTION!
• The TPMS has been optimized for the original equip-
ment tires and wheels. TPMS pressures 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. After-
market wheels can cause sensor damage. Using after-
market tire sealants may cause the Tire Pressure
Monitoring System (TPMS) sensor to become inoper-
able. After using an aftermarket tire sealant it is recom-
mended that you take your vehicle to an authorized
dealer 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 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 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 responsibility to maintain correct tire
pressure using an accurate tire gauge, even if under-infla-
tion 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 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.
