PROCEDURE
1. Remove the tire valve cap.
2. Press the tip of the tire inflation
pressure gauge to the tire valve.
3. Read the pressure using the grad-
uations of the gauge.

5. After completing the tire inflation
pressure measurement and adjust-
ment, apply soapy water to the
valve and check for leakage.
6. Install the tire valve cap.
If a gauge and air pump are not avail-
able, have your vehicle checked by
your Toyota dealer.
CAUTION
Be sure to reinstall the tire valve
caps. Without the valve caps, dirt
or moisture could get into the
valve core and cause air leakage.
If the caps have been lost, have
new ones put on as soon as pos-
sible.
Incorrect tire inflation pressure
may waste fuel, reduce the comfort
of driving, reduce tire life and
make your vehicle less safe to
drive.
If a tire frequently needs refilling,
have it checked by your Toyota deal-
er.
CAUTION
Keep your tires properly inflated.
Otherwise, the following condi-
tions may occur and cause an ac-
cident resulting in death or seri-
ous injuries.
Low tire pressure (underinfla-
tion)—
D Excessive wear
D Uneven wear
D Poor handling
D Possibility of blowouts from an
overheated tire
D Poor sealing of the tire bead
D Wheel deformation and/or tire
separation
D A greater possibility of tire
damage from road hazards
