TIRE PRESSURE MONITOR SYSTEM (TPMS)

The Tire Pressure Monitor System (TPMS) will warn the

driver of a low tire pressure based on the vehicle recom-

mended cold placard pressure.
The tire pressure will vary with temperature by about 1 psi

(7 kPa) for every 12°F (6.5°C). This means that when the

outside temperature decreases, the tire pressure will de-

crease. Tire pressure should always be set based on cold

inflation tire pressure. This is defined as the tire pressure

after the vehicle has not been driven for at least three

hours, or driven less than 1 mile (1.6 km) after a three hour

period. The cold tire inflation pressure must not exceed the

maximum inflation pressure molded into the tire sidewall.

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.

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.
