how to properly inflate the vehicle’s tires. The tire
pressure will also increase as the vehicle is driven. This
is normal and there should be no adjustment for this
increased pressure.
• 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 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 recom-
mended cold placard pressure. Once the low tire pres-
sure 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 Moni-
toring Telltale light will turn off once the system re-
ceivesthe updated tire pressures. The vehicle may need to
be driven for up to 10 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 33 psi (227 kPa). If the ambient
temperature is 68°F (20°C) and the measured tire
pressure is 28 psi (193 kPa), a temperature drop to
20°F (-7°C) will decrease the tire pressure to ap-
proximately 24 psi (165 kPa). This tire pressure is
low enough to turn ON the Tire Pressure Monitor-
ing Telltale light. Driving the vehicle may cause the
tire pressure to rise to approximately 28 psi (193
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.
