D Always use a tire inflation pres-
sure gauge. The appearance of
a tire can be misleading. Besides,
tire inflation pressures that are
even just a few pounds off can de-
grade ride and handling.
D Take special care when adding
air to the compact spare tire.
The smaller tire size can gain
pressure very quickly. Add com-
pressed air in small quantities and
check the pressure often until it
reaches the specified pressure.
D Do not bleed or reduce tire
inflation pressure after driving.
It is normal for the tire inflation
pressure to be higher after driving.
D Never exceed the vehicle capac-
ity weight. Passenger and lug-
gage weight should be located so
that the vehicle is balanced.

INSPECTION AND ADJUSTMENT
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.
4. In case the tire inflation pressure
is not within the prescribed range,
insert the compressed air from the
valve. In case of applying too much
air, press the center of the valve
and release the air to adjust.
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.
