For example, your vehicle has a recommended cold
(parked for more than three hours) tire pressure of
33 psi (227 kPa). If the ambient temperature is
68°F (20°C) and the measured tire pressure is
28 psi (193 kPa), a temperature drop to 20°F
(-7°C) will decrease the tire pressure to
approximately 24 psi (165 kPa). This tire pressure is
sufficiently low enough to turn on the TPMS Warning
Light. Driving the vehicle may cause the tire
pressure to rise to approximately 28 psi (193 kPa),
but the TPMS Warning Light will still be on. In this
situation, the TPMS Warning Light will turn off only
after the tires have been inflated to the vehicle's
recommended cold tire pressure value.
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. Undesirable
system operation or sensor damage may result
when using replacement equipment that is not
of the same size, type, and/or style. The TPMS
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 TPMS feature operation.
CAUTION! (Continued)
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
System 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 underinflated 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.
(Continued)
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 Tire Pressure Monitoring 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.
