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 (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 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 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.
