The system will automatically update and the
TPMS Warning 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 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 orig-

inal equipment tires and wheels. TPMS
pressures and warnings 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
an authorized dealership to have your
sensor function checked.
CAUTION! (Continued)
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.
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.
