Checking brake fluid
60220F04
To check the fluid level, simply look at
the see- through reservoir. The level
should be between the ºMAXº and
ºMINº lines on the reservoir.
It is normal for the brake fluid level to go
down slightly as the brake pads wear. So
be sure to keep the reservoir filled.
If the reservoir needs frequent ref illing, it
may indicate a serious mechanical prob-
lem.
If the level is low, add SAE J1703 or
FMVSS No.116 DOT 3 brake fluid to the
brake reservoir. Remove and replace the reservoir cover
by hand. Fill the brake fluid to the dotted
line. This brings the fluid to the correct
level when you put the cover back on.
Use only newly opened brake fluid. Once
opened, brake fluid absorbs moisture from
the air, and excess moisture can cause a
dangerous loss of braking.
CAUTION
Take care when filling the r
eservoir
because brake fluid can harm your
eyes and damage painted surfaces. If
fluid gets in your eyes, flush your
eyes with clean water.
NOTICE
If you spill the fluid, be sure to wash
it off with water to prevent it fromdamaging the parts or paint.
Checking power steering fluid
60240F08
Check the fluid level on the dipstick. If
necessary, add automatic transmission
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 (60 CÐ80 C or 140 FÐ175 F). You
may also check the level when the fluid
is cold (about room temperature,10 CÐ30 C or 50 FÐ85 F) if the engine
has not been run for about five hours.
a. Clean all dirt from outside of the reser-
voir tank.
b. Remove the filler cap by turning it
counterclockwise and wipe the dipstick
clean.

ÐChecking battery exterior
60170F12
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 nutsÐbut 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 accesso- ries are off before performing main-tenance.
When checking the battery, remove
the ground cable from the negativeterminal (º±º mark) first and rein-stall it last.
Be careful not to cause a short cir- cuit with tools.
Take care no solution gets into thebattery when washing it.

Battery recharging precautions
During recharging, the battery is pro-
ducing hydrogen gas.
Therefore, before recharging:
1. If recharging with the battery installed on the vehicle, be sure to disconnect
the ground cable.
2. Be sure the power switch on the re- charger is off when connecting the
charger cables to the battery and when
disconnecting them.
CAUTION
Always charge the battery in an un-
confined area. Do not charge the
battery in a garage or closed room
where there is not sufficient ventila-
tion.
Only do a slow charge (5A or less).
Charging at a quicker rate is dan-
gerous. The battery may explode,
causing personal injuries.
NOTICE
Never recharge the battery while the
engine is running. Also, be sure allaccessories are turned off.

Adding washer fluid
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 dam-age your vehicle's paint.
Checking the headlight aim
60500F11
Before checking the headlight aim: 1. Be sure that the body around the head- light is not deformed.
2. Park the vehicle on a level spot.
3. The driver gets into the driver's seat and puts the vehicle in a state ready-
ing for a driving (with a full tank).
4. Bounce the vehicle several times.60500F02
To check the headlight aim, check the
vertical and horizontal gauges. 1. Look at the beam angle gauge (vertical movement). The bubble of the gauge
should not deviate from the center of
the gauge by more than two marks on
either side of the gauge.
