Tire valve Tire pressure gauge
1 Remove the tire valve cap.
2 Press the tip of the tire pres-
sure gauge onto the tire
valve.
3 Read the pressure using the
gauge gradations.
4 If the tire inflation pressure is
not at the recommended
level, adjust the pressure.
If you add too much air, press
the center of the valve to
deflate.
5 After completing the tire infla-
tion pressure measurement
and adjustment, apply soapy
water to the valve and check
for leakage.
6 Put the tire valve cap back

■Tire inflation pressure check
interval
You should check ti re inflation pres-
sure every two week s, or at least
once a month. Do not forget to
check the spare.
■Effects of incorrect tire inflation
pressure
Driving with incorrec t tire inflation
pressure may resul t in the following:
●Reduced fuel economy
●Reduced driving comfort and poor
handling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drive train
If a tire needs frequent inflating,
have it checked by your Toyota
