For example, your vehicle may have a
recommended cold (parked for more than three
hours) placard pressure of 30 psi (207 kPa). If
the ambient temperature is 68°F (20°C) and
the measured tire pressure is 27 psi (186 kPa),
a temperature drop to 20°F (-7°C) will
decrease the tire pressure to approximately
23 psi (158 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 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 orig-

inal equipment tires and wheels. TPMS
pressures and warning have been estab-
lished 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 after-
market 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 your authorized
dealer 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 TPMS 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
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 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.
