NOTE: When filling warm tires, the tire pressure may need
to be increased up to an additional 4 psi (30 kPa) above the
recommended cold placard pressure in order to turn the
Tire Pressure Monitoring Telltale Light off.
The system will automatically update and the “Tire Pres-
sure 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 recommended 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 pressure to
approximately 26 psi (179 kPa). This tire pressure is suffi-
ciently low enough to turn ON the “Tire Pressure Moni-
toring 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. TPMS pressures and
warnings have been established for the tire size
equipped on your vehicle. Undesirable system op-
eration 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
Pressure Monitoring System (TPMS) sensor to be-
come 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 pressure, al-
ways reinstall the valve stem cap. This will prevent
moisture and dirt from entering the valve stem,
which could damage the Tire Pressure Monitoring
Sensor.
