(a) Brake System Warning Light
This light has the following functions:
Parking brake reminder
If this light is on, make sure the parking
brake is fully released. The light should
go off.
Low brake fluid level warning
If this light comes on and stays on while
you are driving, slow down and pull off
the road. Then stop the vehicle carefully.
Remember that stopping distance and ped-
al effort may be increased. There maybe
a problem somewhere in the brake sys-
tem. Check the fluid level of the see−
through reservoir.
To make sure the parking brake has not
caused the warning light to come on,
check to see that the parking brake is
fully released.
If the brake fluid level is low...
At a safe place, test your brakes by start-
ing and stopping.
If you judge that the brakes still work
adequately, drive cautiously to your
nearest dealer or shop for repairs.
If the brakes are not working, have the
vehicle towed in for repairs. (For tow-
ing information, see Part 4.)
CAUTION
It is dangerous to continue driving
normally when the brake fluid level is
low.
If the brake fluid level is correct...
Have the warning system checked by your
Toyota dealer.
(b) Driver’s Seat Belt Reminder Light
and Buzzer
The light and buzzer remind you to buckle
up the driver ’s seat belt.
Once the ignition key is turned to ”ON” or
”START”, the reminder light flashes and
buzzer sounds if the driver ’s seat belt is
not pulled out. Unless the driver starts to
pull the shoulder belt out of the retractor,
the light keeps flashing and the buzzer
stops after about 4 to 8 seconds.
(c) Front Passenger ’s Seat Belt Re-
minder Light
The light reminds you to buckle up the
front passenger ’s seat belt.Once the ignition key is turned to ”ON” or
”START”, the reminder light flashes if a
passenger sits in the front passenger seat
and does not pull out the seat belt. Un-
less the front passenger starts to pull the
shoulder belt out of the retractor, the light
stays flashing.
If luggage load is placed on the front
passenger seat, depending on its weight
and how it is placed on the seat, built−in
sensors in the seat cushion may detect
the pressure, causing the reminder light to
come on.
(d) Discharge Warning Light
This light warns that the battery is being
discharged.
If it comes on while you are driving, there
is a problem somewhere in the charging
system.
The engine ignition will continue to oper-
ate, however, until the battery is dis-
charged. Turn off the air conditioning,
blower, radio, etc., and drive directly to
the nearest Toyota dealer or repair shop.
NOTICE
Do not continue driving if the engine
drive belt is broken or loose.

Connecting point
Do not connect the cable to or near
any part that moves when the engine
is cranked.
CAUTION
When making the connections, to
avoid serious injury, do not lean over
the battery or accidentally let the
jumper cables or clamps touch any-
thing except the correct battery termi-
nals or the ground.
5. Start your engine in the normal way.
After starting, run it at about 2000 rpm
for several minutes with the accelerator
pedal lightly depressed.
6. Carefully disconnect the cables in the
exact reverse order: the negative cable
and then the positive cable.
7. Carefully dispose of the battery cover
cloths—they may now contain sulfuric
acid.
8. If removed, replace all the battery vent
plugs.
If the cause of your battery discharging is
not apparent (for example, lights left on),
you should have it checked.If your engine stalls while driving...
1. Reduce your speed gradually, keeping
a straight line. Move cautiously off the
road to a safe place.
2. Turn on your emergency flashers.
3. Try starting the engine again.
If the engine will not start, see ”If your
vehicle will not start”.
CAUTION
If the engine is not running, the pow-
er assist for the brakes and steering
will not work so steering and braking
will be much harder than usual.

CAUTION
BATTERY PRECAUTIONS
The battery produces flammable and
explosive hydrogen gas.
Do not cause a spark from the bat-
tery with tools.
Do not smoke or light a match near
the battery.
The electrolyte contains poisonous
and corrosive sulfuric acid.
Avoid contact with eyes, skin or
clothes.
Never ingest electrolyte.
Wear protective safety glasses when
working near the battery.
Keep children away from the bat-
tery.
EMERGENCY MEASURES
If electrolyte gets in your eyes,
flush your eyes with clean water
immediately and get immediate
medical attention. If possible, con-
tinue to apply water with a sponge
or cloth while en route to the medi-
cal office.
If electrolyte gets on your skin,
thoroughly wash the contact area. If
you feel pain or burning, get medi-
cal attention immediately.
If electrolyte gets on your clothes,
there is a possibility of its soaking
through to your skin, so immediate-
ly take off the exposed clothing and
follow the procedure above, if nec-
essary.
If you happen to swallow electro-
lyte, drink a large quantity of water
or milk. Follow with milk of magne-
sia, beaten raw egg or vegetable
oil. Then go immediately for emer-
gency help.

—Checking battery exterior
Ground cable
Hold−down
clampTerminals
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 (5 A or
less). Charging at a quicker rate is
dangerous. The battery may ex-
plode, causing personal injuries.
NOTICE
Never recharge the battery while the
engine is running. Also, be sure all
accessories are turned off.
Checking and replacing fuses

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.
