The system will automatically update and the
"Tire Pressure Monitoring Telltale Light" will
extinguish once the updated tire pressures
have been received. The vehicle may need to
be driven for up to 20 minutes above 15 mph
(24 km/h) to receive this information.
For example, your vehicle may have a recom-
mended cold (parked for more than three hours)
air pressure of 35 psi (241 kPa). If the ambient
temperature is 68°F (20°C) and the measured
tire pressure is 30 psi (207 kPa), a temperature
drop to 20°F (-7°C) will decrease the tire pres-
sure to approximately 26 psi (179 kPa). This tire
pressure is sufficiently low enough to turn ON
the "Tire Pressure Monitoring Telltale Light."
Driving the vehicle may cause the tire pressure
to rise to approximately 30 psi (207 kPa), but
the "Tire Pressure Monitoring Telltale Light" will
still be ON. In this situation, the "Tire Pressure
Monitoring Telltale Light" will turn OFF only after
the tires have been inflated to the vehicle's
recommended cold placard pressure value.

CAUTION!
• The TPMS has been optimized for the
original equipment tires and wheels. The
TPMS pressures have been established
for the tire size equipped on your vehicle.
Undesirable system operation or sensor
damage may result when using replace-
ment equipment that is not of the same
size, type, and/or style. Aftermarket
wheels can cause sensor damage. Using
aftermarket tire sealants may cause the
Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using
an aftermarket tire sealant it is recom-
mended that you take your vehicle to your
local dealership to have your sensor func-
tion 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 dam-
age the Tire Pressure Monitoring Sensor.
NOTE:
• The TPMS is not intended to replace nor-
mal tire care and maintenance, nor to pro-
vide 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,
even if under-inflation has not reached the
level to trigger illumination of the "Tire
Pressure Monitoring Telltale Light."
• Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor
the actual tire pressure in the tire.
