•

The TPMS will warn the driver of a low tire pressure

if the tire pressure falls below the low-pressure warn-

ing limit for any reason, including low temperature

effects, or 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 warning (Tire Pressure Monitoring Telltale

Light) illuminates, you must increase the tire pressure

to the recommended 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 information.

−

For example, your vehicle may have a recom-

mended 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

26 psi (179 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.
