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 approxi-
mately 23 psi (158 kPa). This tire pressure is sufficiently low
enough to turn ON the TPM Telltale Light. Driving the
vehicle may cause the tire pressure to rise to approximately
27 psi (186 kPa), but the TPM Telltale Light will still be ON.
In this situation, the TPM Telltale Light will turn OFF only
after the tires are inflated to the vehicle’s recommended cold
placard pressure value.

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. 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 after-
market tire sealant it is recommended that you take
your vehicle to your local 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 TPM sensor.
