Look at the see−through coolant reser-
voir when the engine is cold. The cool-
ant level is satisfactory if it is between
the ”FULL” and ”LOW” lines on the
reservoir. If the level is low, add ethyl-
ene−glycol type coolant.
The coolant level in the reservoir will vary
with engine temperature. However, if the
level is on or below the ”LOW” line, add
coolant. Bring the level up to the ”FULL”
line.
Use only ethylene−glycol type coolant.
See information in the next column.
If the coolant level drops within a short
time after replenishing, there may be a
leak in the system. Visually check the
radiator, hoses, engine coolant filler cap,
radiator cap and drain cock and water
pump.
If you can find no leak, have your Toyota
dealer test the cap pressure and check
for leaks in the cooling system.
CAUTION
To prevent burning yourself, do not
remove the radiator cap when the en-
gine is hot.
Coolant type selection
Your coolant must contain ethylene−glycol
antifreeze. In addition to preventing freez-
ing and subsequent damage to the engine,
this will also prevent corrosion. Further
supplemental inhibitors or additives are
neither needed nor recommended.
Read the antifreeze container for informa-
tion on freeze protection. Follow the
manufacturer’s directions for how much to
mix with water. The total capacity of the
cooling system is given in Part 8. We
recommend 50% solution be used for your
Toyota, or a sufficient quantity to provide
protection to about −35C (−31F).
NOTICE
Do not use alcohol type antifreeze or
plain water alone.
Checking brake fluid
To check the fluid level, simply look at
the see−through reservoir. The level
should be between the ”MAX” and
”MIN” 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 refilling, 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.

—Checking battery exterior
TerminalsGround cable
Hold−down clamp
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 accesso-
ries are off before performing main-
tenance.
When checking the battery, remove
the ground cable from the negative
terminal (”−” mark) first and rein-
stall it last.
Be careful not to cause a short cir-
cuit with tools.
Take care no solution gets into the
battery 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 all
accessories are turned off.

If the headlights or other electrical
components do not work, check the
fuses. If any of the fuses are blown,
they must be replaced.
See ”Fuse locations” in Chapter 7−1 for
locations of the fuses.
Turn the ignition switch and inoperative
component off. Pull a suspected fuse
straight out and check it.
Determine which fuse may be causing the
problem. The lid of the fuse box shows
the name of the circuit for each fuse. See
Part 8 of this manual for the functions
controlled by each circuit.
