NOTE:
Once the low tire pressure warning (Tire Pressure Moni-
toring System Warning Light) illuminates, you must increase
the tire pressure to the recommended cold placard pressure
in order for the Tire Pressure Monitoring System Warning
Light to turn off.
The system will automatically update and the Tire Pressure
Monitoring System Warning Light will turn off once the
system receives the updated tire pressures. The vehicle may
need to be driven for up to 20 minutes above 15 mph
(24 km/h) in order for the TPMS to receive this information.
For example, your vehicle may have a recommended cold
(parked for more than three hours) placard 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 approx-
imately 24 psi (165 kPa). This tire pressure is low enough to
turn on the Tire Pressure Monitoring System Warning Light.
Driving the vehicle may cause the tire pressure to rise to
approximately 28 psi (193 kPa), but the Tire Pressure Moni-
toring System Warning Light will still be on. In this situation,
the Tire Pressure Monitoring System Warning Light will
turn off only after the tires are inflated to the vehicle's recom-
mended cold placard pressure value.
NOTE:
When filling warm tires, the tire pressure may need to be
increased up to an additional 4 psi (28 kPa) above the recom-
mended cold placard pressure in order to turn the Tire Pres-
sure Monitoring System Warning Light off.
CAUTION!
• The TPMS has been optimized for the original equip-
ment tires and wheels. TPMS pressures and warning
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 TPM 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 TPM feature operation.
• Using aftermarket tire sealants may cause the Tire Pres-
sure Monitoring System (TPMS) sensor to become
inoperable. After using an aftermarket tire sealant it is
recommended that you take your vehicle to your autho-
rized 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 TPMS sensor.
