Tire inflation pressure  
1 Remove the tire valve cap.  
Checking the specified  
tire inflation pressure  
2 Press the tip of the tire pres-  
sure gauge onto the tire  
valve.  
The recommended cold tire  
inflation pressure and tire size  
are displayed on the tire and  
loading information label.  
(P.397)  
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.  
Inspection and adjust-  
ment procedure  
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  
Greater possibility of tire dam-  
age while driving (due to road  
hazards, expansion joints,  
inflation pressure  
When checking tire inflation pres-  
sure, observe the following:  
sharp edges in the road, etc.)  
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.  
NOTICE  
When inspecting and adjust-  
ing tire inflation pressure  
Be sure to put the tire valve caps  
back on.  
If a valve cap is not installed, dirt  
or moisture may get into the valve  
and cause an air leak, resulting in  
decreased tire inflation pressure.  
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
