1998 TOYOTA T100 ABS

T100(U)63
NOTICE
Do not drive the vehicle with the
warning light on—even for one block.
It may ruin the engine.
(e) Low Fuel Level Warning Light
This light comes on when the fuel level
in the tank becomes nearly empty. Fill up
the tank as soon as possible.
On inclines or curves, due to the move-
ment of fuel in the tank, the low fuel level
warning light may come on earlier than
usual.
(f) Malfunction indicator lamp
This lamp comes on in the following
cases.
a. The fuel tank is completely empty. (See
”Fuel gauge” in Chapter 1−5 for instruc-
tions.)
b. The fuel tank cap is not tightened se-
curely. (See ”Fuel tank cap” in Chapter1 −2 for instructions.)
c. There is a problem somewhere in your
engine or automatic transmission electrical
system. If it comes on while you are driving in
case b, have your vehicle checked/re-
paired by your Toyota dealer as soon as
possible.
(g) ”ABS” Warning Light
This light warns that there is a problem
somewhere in your anti-lock brake system.
If it comes on while you are driving, have
your vehicle checked by your Toyota dealer
as soon as possible.
The light will come on when the ignition
key is turned to the ”ON” position. After
about 3 seconds, the light will go off.
When the ”ABS” 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.
(h) SRS Airbag Warning Light
This light will come on when the ignition
key is turned to the ”ACC” or ”ON” posi-
tion. After about 6 seconds, the light will
go off. This means the airbag system is
operating properly. The warning light system monitors the
front airbag sensors, center airbag sensor
assembly, inflator, warning light, intercon-
necting wiring 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 ”ACC” or
”ON” position or remains on.
The light comes on while driving.
(i) Light Reminder Buzzer
This buzzer will sound if the driver ’s door
is opened while the ignition switch is
turned to the ”LOCK” position with the
headlight switch on. Removing the key will
not stop the buzzer as long as the head-
light switch is on.
(j) Key Reminder Buzzer
This buzzer reminds you to remove the
key when you open the driver’s door with
the ignition key in the ”ACC” or ”LOCK”
position.

(k) Unengaged ”Park” Warning Light
(vehicles with automatic transmis-
sion)
This light warns that the transmission
”Park” mechanism is not engaged. If the
four-wheel drive control is in the ”N” posi-
tion while the selector lever is in the ”P”
position, the transmission will disengage
and the wheels will not lock.
CAUTION
To restore the park function, shift the
four-wheel drive control out of ”N”,
or the vehicle can move.
(l) Automatic Transmission Fluid Tem- perature Warning Light
This light warns that the automatic trans-
mission fluid temperature is too high.
If this light comes on while you are driv-
ing, slow down and pull off the road. Stop
the vehicle at a safe place and put the
selector lever in ”P”. With the engine id-
ling, wait until the light goes off. If the
light goes off, you may start the vehicle
again. If the light does not go off, call a
Toyota dealer or qualified repair shop for
assistance. (m) Low Windshield Washer Fluid Level
Warning Light
The light warns that the windshield washer
fluid level is too low. Add washer fluid at
your earliest opportunity. (For instructions,
see ”Adding washer fluid” in Chapter 7 −3.)
CHECKING SERVICE REMINDER INDICA-
TORS (except the low fuel level warning
light and low windsield washer fluid
level warning light) 1. Apply the parking brake.
2. Turn the ignition key to ”ACC”. The SRS airbag warning light should
come on. It goes off after about 6 se-
conds.
3. Turn the ignition key to ”ON”, but do not start the engine.
All the service reminder indicators ex-
cept the SRS airbag warning light
should come on. The ”ABS” warning
light goes off after about 3 seconds.
If any service reminder indicator or warn-
ing buzzer does not function as described
above, either the bulb is burned out or the
circuit is in need of repair. Have it
checked by your Toyota dealer as soon as
possible.

Brake system
TANDEM MASTER CYLINDER BRAKE SYSTEM
The tandem master cylinder brake system
is a hydraulic system with two separate
sub-systems. If either sub-system s
hould
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 engine vacuum to
power-assist the brakes. If the engine
should quit while you are driving, you can
bring the vehicle to a stop with normal
pedal pressure. There is enough reserve
vacuum for one or two stops–but no more!
CAUTION
Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your vacuum reserve.
Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hard—much harder than nor-
mal. And your braking distance will
be longer.
ANTI-LOCK BRAKE SYSTEM (with
”ABS” 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 stability 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 ”ABS” 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. This will result in
reduced braking performance.
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 capability is dependent on tire
friction with the road surface.

T100(U)123

Even though the anti-lock brake system
is operating, a driver cannot maintain
full control on certain slippery road sur-
faces, when cornering at high speeds,
or in violent maneuvers.
Avoid high speeds on wet roads. The
anti-lock brake system cannot eliminate
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.
”ABS” warning light
This light comes on when the ignition key
is turned to the ”ON” position. After about
3 seconds, the light will go off.
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 as de-
scribed above, or remains on.
The light comes on while driving. Even if the anti-lock brake system should
fail, the brake system will still operate
conventionally. However, when the ”ABS”
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 surfaces. Have your vehicle checked
by your Toyota dealer as soon as pos-
sible.

Avoid jerky steering and sharp turns.
The trailer could hit your vehicle in a
tight turn. Slow down before making a
turn to avoid the necessity of sudden
braking.
Remember that when making a turn,
the trailer wheels will be closer than
the vehicle wheels to the inside of the
turn. Therefore, compensate for this by
making a larger than normal turning
radius with your vehicle.
Crosswinds and rough roads will ad-
versely affect handling of your vehicle
and trailer, causing sway. Pay attention
to the rear from time to time to pre-
pare yourself for being passed by large
trucks or buses, which may cause your
vehicle and trailer to sway. If swaying
happens, firmly grip the steering wheel
and reduce speed immediately but
gradually. Never increase speed. Steer
straight ahead. If you make no extreme
correction with the steering or brakes,
the vehicle and trailer will stabilize.
Be careful when passing other ve-
hicles. Passing requires considerable
distance. After passing a vehicle, do
not forget the length of your trailer and
be sure you have plenty of room be-
fore changing lanes.
In order to maintain engine braking effi-
ciency, do not use fifth gear (manual
transmission) or overdrive (automatic
transmission).
Because of the added load of the trail-
er, your vehicle’s engine may overheat
on hot days (at temperatures over30°C [85 °F]) when going up a long or
steep grade with a trailer. If the engine
coolant temperature gauge indicates
overheating, immediately turn off the air
conditioning (if in use), pull off the road
and stop in a safe spot. Refer to ”If
your vehicle overheats” in Part 4 of
this manual.
Always place wheel blocks under both
the vehicle and trailer wheels when
parking. Apply the parking brake firmly.
Put the transmission in ”P” (automatic)
or in first or reverse (manual). Avoid
parking on a slope with a trailer, but
if it cannot be avoided, do so only
after performing the following:
1. Apply the brakes and hold. 2. Have someone place wheel blocks
under both the vehicle and trailer
wheels.
3. When the wheel blocks are in place, release your brakes slowly until the
blocks absorb the load.
4. Apply the parking brake firmly.
5. Shift into first or reverse (manual) or ”P” (automatic) and turn off the
engine.
When restarting out after parking on a
slope: 1. With the transmission in ”P” position (automatic) or the clutch pedal de-
pressed (manual), start the engine.
(With an automatic transmission, be
sure to keep the brake pedal de-
pressed.)
2. Shift into gear.
3. Release the parking brake (also foot brake on automatic transmission ve-
hicles) and slowly pull or back away
from the wheel blo cks. Stop and ap-
ply your brakes.
4. Have someone retrieve the blo cks.

Checking brake fluid
To check the fluid levels, simply look at
the see-through reservoirs. 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. 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 reservoir
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 from
damaging the parts or paint.
Checking power steering fluid
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 (40 °C–80 °C or 104 °F–175 °F). You may
also check the level when the fluid is cold
(about room temperature, 0 °C–40 °C or
32 °F–104 °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.

3. Release the bulb retaining springand remove the bulb. Install a new
bulb and the bulb retaining spring.
To install a bulb, align the tabs of the
bulb with the cutout of the mounting hole.4. Install the rubber cover and snuggle on the boss.
Make sure the rubber cover fits snugly on
the connector and the headlight body.5. Install the plastic cover with the ”ON” mark upward and turn it clock-
wise. Insert the connector.
Aiming is not necessary after replacing
the bulb. When aiming adjustment is nec-
essary, contact your Toyota dealer.
