of the driver door. The cold
inflation pressure should never be
set lower than the recommended
pressure on the Safety
Compliance Certification Label or
Tire Label.
When weather temperature
changes occur, tire inflation
pressures also change. A 10°F
(6°C) temperature drop can
cause a corresponding drop of
10 psi (0.7 bar) in inflation
pressure. Check the tire pressures
frequently and adjust them to the
correct pressure which can be
found on the Safety Compliance
Certification Label or Tire Label.
To check the tire pressures:
1. Make sure the tires are cool,
meaning they are not hot from
driving even a mile.
2. Remove the cap from the valve
on one tire, then firmly press
the tire gauge onto the valve
and measure the tire pressure.
3. Add enough air to reach the
recommended tire pressure.
4. Replace the valve cap.
5. Repeat this procedure for each
tire, including the spare.
6. Visually inspect the tires to
make sure there are no nails or
other objects embedded that
could poke a hole in the tire
and cause an air leak.
7. Check the sidewalls to make
sure there are no gouges, cuts
or bulges.

Note: If you are checking tire
pressure when the tire is hot, for
example you have driven more than
1.0 mi (1.6 km), never bleed or
reduce tire pressure. The tires are
hot from driving and it is normal for
pressures to increase above
recommended cold pressures. A
hot tire at or below recommended
cold inflation pressure could be
significantly under-inflated.
Note: If you have to drive a
distance to get air for the tires,
check and record the tire pressure
first and add the appropriate air
pressure when you get to the
pump. It is normal for tires to heat
up and the tire pressure to increase
as you drive.
Note: If you over inflate the tire,
release air by pressing on the metal
stem in the center of the valve.
Then recheck the pressure with
your tire gauge.
Note: Some spare tires operate at
a higher inflation pressure than the
other tires. For T-type mini-spare
tires, refer to the Dissimilar spare
wheel and tire assembly
information for a description. Store
and maintain at 60 psi (4.15 bar).
For full-size and dissimilar spare
tires, refer to the Dissimilar spare
wheel and tire assembly
information for a description. Store
and maintain at the higher of the
front and rear inflation pressure as
shown on the Tire Label.
