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 locationsº on page 374 in Sec-
tion 7- 1 for locations of the fuses.
Turn the ignition switch and inoperative
component off. Pull the 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
page 410 in Section 8 for the functions
controlled by each circuit.

Type A fuses can be pulled out by using
the pull- out tool. The location of the pull-
out tool is shown in the illustration.
If you are not sure whether the fuse has
blown, try replacing the suspected fuse
with one that you know is good.
If the fuse has blown, push a new fuse
into the clip.
Only install a fuse with the amperage rat-
ing designated on the fuse box lid.
If you do not have a spare fuse, in an
emergency you can pull out the FR DEFº
or CIGº fuse, which may be dispensable
for normal driving, and use it if its amper-
age rating is the same.
If you cannot use one of the same amper-
age, use one that is lower, but as close
to the rating as possible. If the amperage
is lower than that specified, the fuse
might blow out again but this does not
indicate anything wrong. Be sure to get
the correct fuse as soon as possible and
return the substitute to its original clip.
It is a good idea to purchase a set of
spare fuses and keep them in your ve-
hicle for emergencies.If 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.
You should normalize the moon roof if it
does not operate automatically or the jam
protection function does not operate cor-
rectly after replacing blown fuses. To
normalize the moon roof, see Electric
moon roofº on page 36 in Section 1- 2.
CAUTION
Never use a fuse with a higher am-
perage rating, or any other object, in
place of a fuse. This may cause ex-
tensive damage and possibly a fire.
If any washer does not work or the low
windshield washer fluid level warning
light comes on, the washer tank may be
empty. Add washer fluid.
You may use plain water as washer fluid.
However, in cold areas where tempera-
tures range below the 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.

ASHTRAYS
Front ashtray: To use the ashtray, open
the lid.
When finished with your cigarette, thor-
oughly extinguish it in the ashtray to pre-
vent other cigarette butts from catching
fire. After using the ashtray, close the lid
completely.
To remove the ashtray, pull the lid and
pull it out.
Rear ashtray: To use the ashtray, pull
it out.
When finished with your cigarette, thor-
oughly extinguish it in the ashtray to pre-
vent other cigarette butts from catching
fire. After using the ashtray, close the lid
completely.
To remove the ashtray, press down on the
lock spring plate and pull out.
CAUTION
To reduce the chance of injury in
case of an accident or sudden stop
while driving, always completely close
the ashtray after use.
Front
Rear
The power outlets (12 VDC) are de-
signed for power supply for car acces-
sories.
The key must be in the ACCº or ONº
position for the power outlets to be used.
NOTICE
To prevent the fuse from being
blown, do not use the electricity
over the total vehicle capacity of
12VDC/120W (front and rear outlets
together).
To prevent the battery from being
discharged, do not use the power
outlets longer than necessary when
the engine is not running.
Close the power outlet lids when
the power outlets are not in use.
Inserting a foreign object other than
the appropriate plug that fits the
outlet, or allowing any liquid into
the outlet may cause electrical fail-
ure or short circuits.

DTC C1361/91 SHORT CIRCUIT IN ABS MOTOR FAIL SAFE
RELAY CIRCUIT
CIRCUIT DESCRIPTION
The VSC motor relays consist of 2 relays are included in the ABS R/B.
The VSC cut relay is turned on after turning the ignition switch to the ON position. If the DTCs in the
ABS pump motor circuit are memorized, the VSC cut relay cuts off the power supply to the VSC motor
relay and performs the fail safe.
While any of the ABS, BA, TRAC and VSC is operating, the skid control ECU (included in the actuator)
turns the VSC motor relay on to operate the actuator pump motor.
If the voltage applied to the VSC motor relays (+BM) drops below the condition that detects the DTCs
due to the shortage of the battery or alternator output, the DTCs may be memorized.
