also increase as the vehicle is driven - this is normal and

there should be no adjustment for this increased pres-

sure.
The TPMS 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 TPMS 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 recommended

cold placard pressure. Once the low tire pressure warn-

ing (Tire Pressure Monitoring [TPM] Telltale Light) illu-

minates, you must increase the tire pressure to the

recommended cold placard pressure in order for the

“TPM Telltale Light” to turn off. The system will auto-

matically update and the “TPM 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 (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 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 (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 pres-

sure value.
