The tire pressure will vary with temperature by about

1 psi (6.9 kPa) for every 12°F (6.5°C). This means that

when the outside temperature decreases, the tire pressure

will decrease. Tire pressure should always be set based

on cold inflation tire pressure. This is defined as the tire

pressure after a vehicle has not been driven for more than

three hours - and in outside ambient temperature. Refer

to “Tires – General Information” in “Starting and

Operating” for information on 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.

TPMS will warn the driver of a low tire pressure if the tire

pressure falls below the low pressure warning threshold

for any reason, including low temperature effects, or

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 recom-

mended cold placard pressure. Once the low tire pressure

warning has been illuminated, the tire pressure must be

increased to the recommended cold placard pressure in

order for the “TPMS Warning Lamp” to be turned off.

The system will automatically update and the “TPMS

Warning Lamp” will extinguish once the updated tire

pressures have been received. The vehicle may need to be

driven for up to 20 minutes above 15 mph (24 km/h) to

receive this information.

For example, your vehicle has a recommended 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 approximately 24 psi (165 kPa). This tire

pressure is sufficiently low enough to turn on the “TPMS

Lamp.” Driving the vehicle may cause the tire pressure to

rise to approximately 28 psi (193 kPa), but the “TPMS
