Do-it-yourself maintenance - Engine and Chassis -> Checking tire inflation pressure for Your Toyota Corolla 4 Door Eighth Generation (2000-2006)

Checking tire inflation  
pressure  
Clean all dirt from outside of the reservoir  
tank and look at the fluid level. If the fluid  
is cold, the level should be in the “COLD”  
range. Similarly, if it is hot, the fluid level  
should be in the “HOT” range. If the level  
is at the low side of either range, add  
automatic transmission fluid DEXRONr  
II or III to bring the level within the range.  
To remove the reservoir cap, turn it coun-  
terclockwise and lift up. To reinstall it,  
turn it clockwise. After replacing the reser-  
voir cap, visually check the steering box  
case, vane pump and hose connections  
for leaks or damage.  
CAUTION  
The reservoir tank may be hot so be  
careful not to burn yourself.  
NOTICE  
Avoid overfilling, or the power steer-  
ing could be damaged.

Keep your tire inflation pressures  
at the proper level.  
The following instructions for  
checking tire inflation pressure  
should be observed:  
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. The passenger and  
luggage weight should be located  
so that the vehicle is balanced.  
The recommended cold tire inflation  
pressures, tire sizes and the com-  
bined weight of occupants and cargo  
(vehicle capacity weight) are de-  
scribed on page 252 and 255. They  
are also on the tire and loading infor-  
mation label. Either type A or type B  
of the tire and loading information la-  
bel is affixed on your vehicle as  
shown.  
You should check the tire inflation  
pressure every two weeks, or at least  
once a month. And do not forget the  
spare!  
D The  
pressure  
should  
be  
checked only when the tires are  
cold. If your vehicle has been  
parked for at least 3 hours and has  
not been driven for more than 1.5  
km or 1 mile since, you will get  
an accurate cold tire inflation pres-  
sure reading.  
D Always use a tire pressure  
gauge. The appearance of a tire  
can be misleading. Besides, tire  
inflation pressures that are even  
just a few pounds off can degrade  
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.

Tire pressure gauge  
CAUTION  
pressure measurement and ad-  
justment, apply soap water to the  
valve and check the leakage.  
Keep your tires properly inflated.  
Otherwise, the following condi-  
tions may occur and cause an ac-  
cident resulting in death or seri-  
ous injuries.  
6. Install the tire valve cap.  
If the gauge and the air pump are not  
available, have your vehicle checked  
by your Toyota dealer.  
Low tire pressure (underinfla-  
tion)—  
CAUTION  
D Excessive wear  
D Uneven wear  
D Poor handling  
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.  
INSPECTION AND ADJUSTMENT  
PROCEDURE  
D Possibility of blowouts from  
overheated tire.  
1. Remove the tire valve cap.  
2. Press the tip of the tire pressure  
gauge to the tire valve.  
D Poor sealing of the tire bead  
D Wheel deformation and/or tire  
separation  
3. Read the pressure using a gradua-  
tion of the gauge.  
Incorrect tire inflation pressure may  
waste fuel, reduce the comfort of driv-  
ing, reduce tire life and make your ve-  
hicle less safe to drive.  
If a tire frequently needs refilling,  
have it checked by your Toyota deal-  
er.  
D A greater possibility of tire  
damage from road hazards  
4. In case that the tire inflation pres-  
sure 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 ad-  
just.
