The TPM System will warn the driver of a low tire
pressure if the tire pressure falls below the low-pressure
warning limit for any reason, including low temperature
effects and natural pressure loss through the tire.
The TPM System will continue to warn the driver of low
tire pressure as long as the condition exists, and will not
turn off until the tire pressure is at or above the recom-
mended cold placard pressure. Once the low tire pressure
warning (Tire Pressure Monitoring Telltale Light) illumi-
nates, you must increase the tire pressure to the recom-
mended cold placard pressure in order for the "Tire
Pressure Monitoring Telltale Light" to turn off. The
system will automatically update and the "Tire Pressure
Monitoring Telltale 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
(25 km/h) in order for the TPMS to receive this informa-
tion.
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 approximately 23 psi (157 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 27 psi
(186 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 are inflated to the vehicle's recommended cold
placard pressure value.
