Check the fluid level through the reser-
voir. If necessary, add automatic trans-
mission fluid DEXRON [
II or -III.
If the vehicle has been driven around 80
km/h (50 mph) for 20 minutes (a little more
in frigid temperatures), the fluid is hot (40 C ' 80 C or 104 F ' 175 F). You
may also check the level when the fluid is
cold (about room temperature, 0 C '
40 C or 32 F ' 104 F) if the engine has
not been run for about five hours.
a. Clean all dit from outside of the reser- voir tank.
b. Remove the filler cap by turning it
counterclockwise and wipe the dipstick clean. c. Reinstall the filler cap.
d. Remove the filler cap again and look at the fluid level. If the fluid is cold, the level
should be in the COLDº range. Similarly, if it is hot, the fluid level should be in the
HOTº range. If the level is at
the low side
of either range, add automatic transmis-
sion fluid DEXRON -II or III to bring the
level within range.
e. After replacing the filler cap, visually check the steering box case, vane pump
and hose connections for leaks or dam-age.
CAUTION
The reservoir tank may be hot so be careful not to burn yourself.!
Avoid overfilling, or the power steering could be damaged.
NOTICE
Keep your tire pressures at the proper level.
The recommended cold tire pressures, tire size and the cargo weight are also giv-
en in Part 8.
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 tread bead.
If the tire pressure is excessively low,
there is the possibility of wheel 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 pos-
sibility of tire damage from road hazards.
If a tire frequently needs refilling, have it
checked by your Toyota dealer.

Check the battery for corroded or
loose terminal connections, cracks, or
loose hold-down clamp.
a. If the battery is corroded, wash it off with a solution of warm water and baking
soda. Coat the outside of the terminals with grease to prevent further corrosion.
b. If the terminal connections are loose, tighten their clamp nuts±but do not over- tighten.
c. Tighten the hold-down clamp only
enough to keep the battery firmly in place.
Overtightening may damage the battery case.
NOTICE
Be sure the engine and all acces-
sories are off before performing
maintenance.
When checking the battery, re-move the ground cable from the
negative terminal (-º mark) first
and reinstall it last.
Be careful not to cause a short cir-cuit with tools.
Take care no solution gets into thebattery when washing it.
There are two types of batteries: Main-
tenance type and non-maintenance type. A non-maintenance battery has MAIN-
TENANCE FREE BATTERYº on its top. A
maintenance type battery does not havesuch indication. Maintenance type batteryÐ Check the fluid condition by the fluid level
lines on the side of the battery. Or if the
battery has a hydrometer on its top, you
can also check the hydrometer. Non-maintenance batteryÐ
Check the battery condition by the
hydrometer on the top of the battery.

ADDING DISTILLED WATER (MAINTE-
NANCE TYPE BATTERY ONLY)
1. Remove the vent plugs.
2. Add distilled water to cells needingfluid.
If the side of your battery is covered,
check the water level by looking down di-
rectly above the cell as illustrated above.
3. Retighten the vent plugs securely
NOTICE
Do not overfill the cells. Excess electrolyte could squirt out of the
battery during heavy charging,causing corrosion or damage.
During recharging, the battery is pro-
ducing hydrogen gas. Therefore, before recharging:
1. Maintenance type batteriesÐRemove the vent plugs.
2. If recharging with the battery installed on the vehicle, be sure to disconnect the ground cable.
3. Be sure the power switch on the re- charger is off when connecting the
charger cables to the battery and
when disconnecting them.
Always charge the battery in an
unconfined area. Do not charge
the battery in a garage or closed
room where there is not sufficient ventilation.
Non-maintenance batteries: Only
do a slow charge (5A or less).
Charging at a quicker rate is dan-
gerous. The battery may explode,
causing personal injuries.
Maintenance type batteries: Be sure to remove the vent plugs be-fore recharging. CAUTION
!
NOTICE
Never recharge the battery while the
engine is running. Also, be sure all
accessories are turned off.
Battery recharging precautions

196If the new fuse immediately blows out, there is a problem with the electrical sys-
tem.
Have your Toyota dealer correct it as
soon as possible.
Never use a fuse with a higher
amperage rating, or any other
object, in place of a fuse. This maycause extensive damage and
possibly a fire. CAUTION
!
If any washer does not work, the wash-
er tank may be empty. Add washer fluid.
You may use plain water as washer fluid.
However, in cold areas where tempera-
tures range below freezing point, use
washer fluid containing antifreeze. This
product is available at your Toyota dealer
and most auto parts stores. Follow the
manufacturer 's directions for how much
to mix with water.
NOTICE
Do not use engine antifreeze or any other substitute because it may
damage your vehicle's paint.
The following illustrations show how to
gain access to the bulbs. When replacing
a bulb, make sure the ignition switch and
light switch are off. Use bulbs with the wattage ratings given in the table.
NOTICE
Only use a bulb or unit of the listed type.
