INSPECTION AND MAINTENANCE
Tire Inflation Pressure
Tire inflation pressure should be
checked when the tire is cold. "Cold
tire inflation pressure" is the pressure
in a tire that has been driven less than
1 mile (1.6 km) or has been standing
for three hours or more.
The front, rear and spare tire pressure
specifications for your vehicle are
shown below and are listed on the Tire
and Loading Information Label, which
is located on the driver's door lock pil-
lar. The Tire and Loading Information
Label contains the following informa-
tion:
• Seating Capacity
• Maximum Allowed
Weight of Occupants and Cargo
• Original Tire Size

NOTE:
The tire inflation pressure will change
due to changes in atmospheric pres-
sure, temperature or tire temperature
when driving. To reduce the chance
that the low tire pressure warning light
will come on due to normal changes in

temperature and atmospheric pres-
sure, it is important to check and
adjust the tire pressures when the tires
are cold. Tires that appear to be at the
specified pressure when checked after
driving, when the tires are warm, could
have pressure below the specification
when the tires cool down. Also, tires
that are inflated to the specified pres-
sure in a warm garage may have pres-

sure below the specification when the
vehicle is driven outside in very cold
temperature. If you adjust the tire
pressure in a garage that is warmer
than the outside temperature, you
should add 1 psi to the recommended
cold tire inflation pressure for every
10°F difference between garage tem-

sure on the vehicle's Tire and Load-
ing Information Label or in the
owner's manual.
2) Remove the valve cap from the tire
valve stem.
3) Using a reliable pressure gauge,
measure the tire inflation pressure
by pressing the tire gauge firmly
onto the valve to get a pressure
measurement.
