Tire pressure gauge
B
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 vehi-
cle is balanced.
WARNING
■
Proper inflation is critical to
save tire performance
Keep your tires properly inflated.
If the tires are not properly
inflated, the following conditions
may occur which could lead to an
accident resulting in death or seri-
ous injury:
●
Excessive wear
●
Uneven wear
●
Poor handling
●
Possibility of blowouts resulting
from overheated tires
●
Air leaking from between tire
and wheel
●
Wheel deformation and/or tire
damage
