WHEELS AND TIRES

Adjusting tire pressure
Tire pressure decreases over time, which is nor-
mal. The tire pressure must therefore be
adjusted to maintain the recommended tire pres-
sure.
Use the recommended inflation pressure for cold
tires for optimal tire performance and wear.
NOTE
To help prevent incorrect inflation pressure,
pressure should be checked when the tires
are cold. The tires are considered to be cold
when they have reached the same tempera-
ture as the ambient temperature (about 3
hours after the vehicle was last driven). After
driving for a few kilometers, the tires will warm
up and the pressure will increase.
1. Remove the valve cap from the tire and press
the air pressure gauge firmly onto the valve.
2. Inflate the tire to the correct inflation pres-
sure; see the tire pressure placard on the
driver's side B pillar for recommended pres-
sures for factory-mounted tires.
3. Screw the valve cap back on.
NOTE
•
After inflating a tire, always replace the
valve cap to help prevent valve damage
caused by gravel, dirt, etc.
•
Use plastic valve caps only. Metal caps
could corrode and become difficult to
remove.
4. Visually inspect the tire to make sure there
are no nails or other embedded objects that
could puncture the tire and cause air leak-
age.
5. Check the sidewalls to make sure there are
no gouges, cuts, bulges or other irregulari-
ties.
6. Repeat this procedure for each tire, including
the spare tire

.
NOTE
If you have overfilled the tire, release air by
pushing on the metal stem in the center of
the valve. Then recheck the pressure with
your tire gauge.
Some spare tires require higher inflation pres-
sure than the other tires. Consult the tire
inflation pressure table or the inflation pres-
sure placard.
