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
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 TPM System 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 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 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
