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 may be
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.
Brake system failure warning
The light may stay on for about 60 sec-
onds after the engine is started. It is nor-
mal if it goes out after a while.
If the brake system warning light stays on
even with the parking brake being re-
leased, the brake system may fail. Con-
tact your Toyota dealer.
If the hydraulic boost pressure is lowered,
the warning light comes on and buzzer
sounds continuously. Immediately stop
your vehicle at a safe place and contact
your Toyota dealer. In this case, the
brakes may not work properly. if they do
not work well, depress the brake pedal
firmly.

Depressing the brake pedal repeatedly
may turn on the warning light and buzzer.
It is normal if the light goes out and the
buzzer stops sounding after a few sec-
onds.
CAUTION
Continued driving with an inoperative
brake booster is dangerous.
(b) Driver's Seat Belt Reminder Light
and Buzzer
Once the ignition key is turned to ºONº or
ºSTARTº, the reminder light flashes and
the buzzer sounds if the driver 's seat belt
is not fastened. Unless the driver fastens
the belt, the light keeps on flashing and
the buzzer sounds 4 to 8 seconds.
(c) Front Passenger 's Seat Belt Re- minder Light
Once the ignition key is turned to ºONº or
ºSTARTº, the reminder light flashes if a
passenger sits in the front passenger seat
and does not fasten the seat belt. Unless
the front passenger fastens the belt, 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.
(e) Malfunction Indicator Lamp
This lamp comes on in the following
cases.
a. The fuel tank is completely empty. (See
ºFuel gaugeº in Chapter 1- 5 for instruc-
tions.)
b. The fuel tank cap is not tightened se-
curely. (See ºFuel tank capº in Chapter
1- 2 for instructions.)
c. There is a problem somewhere in your

(g) SRS Warning Light
This light will come on when the igni-
tion key is turned to the ºACCº or
ºONº position. After about 6 seconds,
the light will go off. This means the
system of the airbag and front seat belt
pretensioners are operating properly.
The warning light system monitors the air-
bag sensor assembly, front airbag sen-
sors, seat belt pretensioner assemblies,
inflators, warning light, interconnecting wir-
ing and power sources.
If either of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Toyota dealer as
soon as possible to service the vehicle.
The light does not come on when the
ignition key is turned to the ºACCº or
ºONº position or remains on.

somewhere in your anti- lock brake sys-
tem.
If it comes on while you are driving, have
your vehicle checked by your Toyota deal-
er as soon as possible. However, it is
normal if the light goes out.
The light will come on when the ignition
key is turned to the ºONº position. After
a few seconds, the light will go off. There
may be the case that the ºABSº warning
light stays on for about 60 seconds after
the engine is started. It is normal if it
goes out after a while.
Depressing the brake pedal repeatedly
may turn on the light. It is normal if it
goes off after a few seconds.
When the ºABSº warning light is on (and
the brake system warning light is off), the
brake system operates conventionally but
anti- lock brake system is not assisting
brake performance so that the wheels can
lock- up during sudden braking or braking
on slippery road surfaces.
However, the anti- lock brake system does
not operate when the rear differential is
locked. It is normal operation for the
ºABSº warning light to be on at this time.
CAUTION
While the ºABSº warning light is on,
if either of the following conditions
occurs, immediately stop your vehicle
at a safe place and contact your
Toyota dealer.
The brake system warning light
stays on even with the parking
brake being released.

To lock the rear differential, push and
turn the switch clockwise until it clicks.
Be sure to stop the wheels before locking
the differentials.
For easy locking, turn the lock switch and
gently depress the accelerator pedal.
The indicator light will blink when the
switch is turned on. Wait a few seconds
for the system to complete operation. Af-
ter the differential is locked, the light will
stop blinking and remain on.
The anti±lock brake system does not oper-
ate when the rear differential is locked. It
is normal operation for the ºABSº warning
light to be on at this time.
CAUTION
Do not lock the differentials until
the wheels have stopped spinning.
Otherwise, the vehicle may move in
an unexpected direction when the
differential locks are engaged, re-
sulting in an accident. This may
also lead to possible damage to dif-
ferential lock component parts.
Do not drive over 8 km/h (5 mph)
when the differentials are locked.
To unlock the differentials, turn the
switch fully counterclockwise.
Unlock the differentials as soon as the
vehicle moves out.
For easy unlocking, slightly turn the steer-
ing wheel in either direction while the ve-
hicle is in motion.

Brake system
BRAKE SYSTEM
This brake system has two independent
hydraulic circuits. If either circuit should
fail, the other will still work. However, the
pedal will be harder to press, and your
stopping distance will be longer. Also, the
brake system warning light may come on.
CAUTION
Do not drive your vehicle with only a
single brake system. Have your
brakes fixed immediately.
BRAKE BOOSTER
The brake booster uses brake fluid pres-
surized by the pump to power- assist the
brakes. If the brake booster fails during
driving, the brake system warning light
comes on and buzzer sound continuously.
In this case the brakes may not work
properly. If they do not work well, depress
the brake pedal firmly. If the brake system
warning light comes on, immediately stop
your vehicle and contact your Toyota deal-
er.

There may be the case that the brake
system warning light stays on for a
bout
60 seconds after the engine is started. It
is normal if the light goes out after a
while.
Depressing the brake pedal repeatedly
may turn on the brake system warning
light and buzzer. It is normal if the light
goes out and the buzzer stops sounding
after a few seconds.
You may hear a small sound in the engine
compartment after the engine is started or
the brake pedal is depressed repeatedly.
This is a pump pulsating sound of the
brake system, and it is not a malfunction.
CAUTION
Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your brake fluid
pressure reserve.
Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hardÐmuch harder than nor-
mal. And your braking distance will
be longer.
ANTI- LOCK BRAKE SYSTEM (with
ºABSº warning light)
The anti-lock brake system is designed to
automatically help prevent lock-up of the
wheels during sudden braking or braking
on slippery road surfaces. This assists in
providing directional stab ility and steering
performance of the vehicle under these
circumstances.
The anti- lock brake system becomes op-
erative after the vehicle has accelerated
to a speed in excess of approximately 10
km/h (6 mph). It stops operating when the
vehicle decelerates to a speed below
approximately 5 km/h (3 mph).
You may hear a sound in the engine
compartment for a few seconds when the
engine is started or just after the vehicle
is started. This means that the anti- lock
brake system is in the self check mode,
and does not indicate a malfunction.
Effective way to press the ºABSº brake
pedal: When the anti- lock brake system
function is in action, you may feel the
brake pedal pulsating and hear a noise.
In this situation, to let the anti- lock
brake system work for you, just hold the
brake pedal down more firmly. Do not
pump the brake in a panic stop. Pump-
ing the brake pedal makes the stopping
distance longer.
The brake pedal pulsation caused by the
anti- lock brake system may indicate haz-
ardous road surface conditions. Although
the anti- lock brake system assists in pro-
viding vehicle control, it is still important
to drive with all due care, because the
anti- lock brake system cannot overcome
the laws of physics that act on your ve-
hicle: Braking capab ility is dependent on tire
friction with the road surface.
Even though the anti- lock brake sys-
tem is operating, a driver cannot main-
tain full control on certain slippery road
surfaces, when cornering at high
speeds, or in violent maneuvers.

New L/C100(U)
160
Avoid high speeds on wet roads. The
anti- lock brake system cannot elimi-
nate the risk of hydroplaning and loss
of tire friction.
Always maintain a safe distance from the
vehicle in front of you. Compared with
vehicles not fitted with an anti- lock brake
system, your vehicle may r equire a longer
stopping distance in the following cases:
Driving on rough, gravel or snow- cov-
ered roads.
Driving with tire chains installed.
Driving on roads where the road sur-
face is pitted or has other differences
in surface height.
CAUTION
Do not use tires other than the
manufacturer 's designated tires, and
do not mix tires or wheels of differ-
ent sizes. You may prevent the anti-
lock brake system from operating at
full effectiveness.
Vehicles with rear differential lock sys-
tem 'The anti- lock brake system does not
operate when the rear differential is
locked. It is normal operation for the
ºABSº warning light to be on at this time.
ºABSº WARNING LIGHT
This light comes on when the ignition key
is turned to the ºONº position. After a few
seconds, the light will go off. There may
be the case that the ºABSº warning light
stays on for about 60 seconds after the
engine is started. It is normal if the light
goes out after a while.
Depressing the brake pedal repeatedly
may turn on the light. It is normal if it
goes off after a few seconds.
When the light is on with the rear differen-
tial locked, it indicates the anti- lock brake
system will not operate. If any of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Toyota dealer as
soon s possible to service the vehicle.
The light does not come on as de-
scribed above, or remains on.
The light comes on while driving with
the rear differential unlocked.
The light does not come on with the
rear differential locked.
The system comes into operation with
the rear differential locked.
Even if the anti-lock brake system should
fail, the brake system will still operate
conventionally. However, when the ºABSº
warning light is on (and the brake system
warning light is off), the anti- lock brake
system is not assisting brake performance
so that the wheels can lock- up during
sudden braking or braking on slippery
road surface. Have your vehicle checked
by your Toyota dealer as soon as pos-
sible.
