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 DEXRON 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.
Checking tire pressure
Keep your tire pressures at the proper
level.
The recommended cold tire pressures, tire
size and the vehicle capacity weight are
given in Section 8. They are also on the
tire pressure label as shown.
You should check the tire pressures every
two weeks, or at least once a month. And
don’t forget the spare!
Incorrect tire pressure can reduce tire
life and make your vehicle less safe to
drive. Low tire pressure results in excessive
wear, poor handling, reduced fuel econo-
my, and the possibility of blowouts from
overheated tires. Also, low tire pressure
can cause poor sealing of the tire bead.
If the tire pressure is excessively low,
there is the possibility of w
heel deforma-
tion and/or tire separation.
High tire pressure produces a harsh ride,
handling problems,excessive wear at the
center of the tire tread, and a greater
possibility of tire damage from road haz-
ards.
If a tire frequently needs ref illing, have it
checked by your Toyota dealer.
The following instructions for checking
tire pressure should be observed:
The pressure should be checked only
when the tires are cold. If your ve-
hicle 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 pressure
reading.
Always use a tire pressure gauge.
The appearance of a tire can be mis-
leading. Besides, tire pressures that
are even just a few pounds off can
degrade ride and handling.
