7-3. Do-it-yourself maintenance
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
on.
■ Tire inflation pressure check
interval
You should check tire inflation pres-
sure every two weeks, or at least
once a month.
Do not forget to check the spare.
■ Effects of incorrect tire inflation
pressure
Driving with incorrect tire inflation
pressure may result 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
dealer.
■ Instructions for checking tire
inflation pressure
When checking tire inflation pres-
sure, observe the following:
● Check only when the tires are
cold.
If your vehicle has been parked for
at least 3 hours or has not been
driven for more than 1 mile or 1.5
km, you will get an accurate cold
tire inflation pressure reading.
● Always use a tire pressure gauge.
It is difficult to judge if a tire is
properly inflated based only on its
appearance.
● It is normal for the tire inflation
pressure to be higher after driving
as heat is generated in the tire. Do
not reduce tire inflation pressure
after driving.
● Never exceed the vehicle capacity
weight. Passengers and luggage
weight should be placed so that
the vehicle is balanced.
