Collision from the rear
Collision from the side Vehicle roll- over
The SRS airbags are not designed to
inflate if the vehicle is subjected to a
side or rear impact, if it rolls over, or
if it is involved in a low- speed frontal
collision.
The SRS airbag system mainly consists of
the following components and their loca-
tions are shown in the illustration.
1 SRS airbag warning light
2 Airbag module for driver (airbag and inflator)
3 Passenger airbag cutoff switch
4 Airbag module for passenger (airbag and inflator)
5 Airbag sensor assembly
The airbag sensor assembly consists of a
safing sensor and airbag sensor. In a severe frontal impact, sensors detect
deceleration and the system triggers the
airbag inflators. Then a chemical reaction
in the inflators momentarily fills the air-
bags with non- toxic gas to help restrain
the forward motion of the occupants.
When the airbags inflate, they produce a
fairly loud noise and release some smoke
along with non- toxic gas. This does not
indicate a fire. Be sure to wash off any
residue as soon as possible to prevent
minor skin irritation.
Deployment of the airbags happen in a
fraction of a second, so the airbags must
inflate with considerable force. While the
system is desi
gned to reduce serious inju-
ries, it may also cause minor burns or
abrasions and swellings.
Parts of the airbag module (steering wheel
hub, dashboard) may be hot for several
minutes, but the airbags themselves will
not be hot. The airbags are designed to
inflate only once.
A crash severe enough to inflate the air-
bags may break the windshield as the
vehicle buckles. In vehicles with a pas-
senger airbag the windshield may also be
damaged by absorbing some of the force
of the inflating airbag.

NOTICE
Do not drive the vehicle with the warning light onÐeven for one block.It may ruin the engine.
(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
engine or automatic transmission electrical
system.
If it comes on while you are driving in
case c, have your vehicle checked/re-
paired by your Toyota dealer as soon as
possible. (f) 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.
(g) ºABSº Warning Light This light warns that there is a problem
somewhere in your anti-lock brake system.
If the light comes on while you are driv-
ing, 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 ºONº position. After
a few seconds, the light will go off.
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. Vehicles with rear differential lock sys-
temÐ
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.
(h) SRS Airbag 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
airbag system is operating properly.
The warning light system monitors the air-
bag sensor assembly, inflator, warning
light, interconnecting 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 ºACCº or
ºONº position or remains on.
The light comes on while driving.

(i) Unengaged ºParkº Warning Light (ve-
hicles with automatic transmission)
This light warns that the transmission
ºParkº mechanism is not engaged. If the
front drive control lever is in the ºNº posi-
tion while the selector lever is in the ºPº
position, the transmission will disengage
and the wheels will not lock.
CAUTION
To restore the park function, shift the
front drive control lever out of ºNº,
or the vehicle can move.
(j) 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 ºPº. 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. (k) Low Windshield Washer Fluid Level
Warning Light (Canada)
The light warns that the windshield washer
fluid level is too low. Add washer fluid at
your earliest opportunity. (For instructions,
see ºAdding washer fluidº in Chapter 7- 3.)
(l) Light Reminder Buzzer This buzzer will sound if the driver 's door
is opened while the ignition switch is
turned to the ºLOCKº position with the
headlight switch on. Removing the key will
not stop the buzzer as long as the head-
light switch is on.
(m) Key Reminder Buzzer This buzzer reminds you to remove the
key when you open the driver 's door with
the ignition key in the ºACCº or ºLOCKº
position. CHECKING SERVICE REMINDER INDICA-
TORS (except the low fuel level warning
light and low windshield washer fluid
level warning light)
1. Apply the parking brake.
2. Turn the ignition key to ºACCº. The SRS airbag warning light should
come on. It goes off after about 6 se-
conds.
3. Turn the ignition key to ºONº, but do not start the engine.
All the service reminder indicators ex-
cept the SRS airbag warning light
should come on. The ºABSº warning
light goes off after a few 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.

CAUTION
Do not use the rear differential lock
in the conditions other than above.
Large steering effort and careful cor-
nering control will be required.
Lock
Unlock
To lock the rear differential, push the
switch.
Be sure to stop the wheels before locking
the differential.
For easy locking, depress the clutch ped-
al, push the lock switch and slowly re-
lease the clutch 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 differential until the
wheels have stopped spinning.
Otherwise, the vehicle may move in
an unexpected direction when the
differential lock is engaged, result-
ing in an accident. This may also
lead to possible damage to differen-
tial lock component parts.
Do not drive over 8 km/h (5 mph)
when the differential is locked.
To unlock the differential, push the
switch once again.
Unlock the differential as soon as the ve-
hicle moves out.
For easy unlocking, slightly turn the steer-
ing wheel in either direction while the ve-
hicle is in motion.
When the differential lock is disengaged,
the indicator light will go out.
Except for Pre Runner models '
The differential will also unlock if you shift
the front drive control lever out of ºL4º.
Never forget to turn off the switch after
using this feature.

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 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. This will result in re-
duced 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 capab ility is dependent on tire
friction with the road surface.
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.

'98 Tacoma (U)145
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
systemÐ
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.
Ty p e A
Ty p e B ºABSº warning light

seconds, the light will go off.
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 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.
Vehicles with rear differential lock
systemÐ The light comes on while driving with
the rear differential unlocked.

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 surfaces. Have your vehicle checked
by your Toyota dealer as soon as pos-
sible.
Brake pad wear limit indicators
The brake pad wear limit indicators on
your disc brakes give a warning noise
when the brake pads are worn to where
replacement is required.
If you hear a squealing or scraping noise
while driving, have the brake pads
checked and replaced by your Toyota
dealer as soon as possible. Expensive ro-
tor damage can result if the pads are not
replaced when necessary.Luggage stowage pr
ecautions
When stowing luggage or cargo in the
vehicle, observe the following: Put luggage or cargo in the rear deck
when at all possible. Be sure all items
are secured in place.
Be careful to keep the vehicle bal-
anced. Locating the weight as far for-
ward as possible helps maintain bal-
ance.
For better fuel economy, do not carry
unneeded weight.CAUTION
To prevent luggage or packages
from sliding forward during braking,
do not stack anything behind the
front seats higher than the seat-
backs (Xtra-cab models). Keep lug-
gage or packages low, as close to
the floor as possible.
Never allow anyone to ride in the
rear deck. It is not designed for
passengers. They should ride in
their seats with their seat belts
properly fastened. Otherwise, they
are much more likely to suffer seri-
ous bodily injury, in the event of
sudden braking or a co llision.

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 over 305C [85 5F]) 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 ºIf
your vehicle overheatsº 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 ºPº (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 un- der 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
ºPº (automatic) and turn off the engine.
When restarting out after parking on a
slope:
1. With the transmission in ºPº 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 apply
your brakes.
4. Have someone retrieve the blo cks.
CAUTION
Do not exceed 72 km/h (45 mph) or
the posted towing speed limit,
whichever is lower. Because insta-
bility (swaying) of a towing vehicle-
trailer combination usually in-
creases as the speed increases, ex-
ceeding 72 km/h (45 mph) may
cause loss of control.
Slow down and downshift before
descending steep or long downhill
grades. Do not make sudden down-
shifts.
Avoid holding the brake pedal down
too long or too frequently. This
could cause the brakes to overheat
and result in reduced braking effi-
ciency.

'98 Tacoma (U)209
To check the fluid level, simply look at
the see-through reservoir. The level
should be between the ºMAXº and
ºMINº 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 ref
illing, 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 r eservoir
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 fromdamaging the parts or paint.
Checking power steering fluid
If cold add
If cold O.K.
If hot add If hot O.K.
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 5C±80 5C or 104 5F±175 5F). You may
also check the level when the fluid is cold
(about room temperature, 0 5C±40 5C or
32 5F±104 5F) 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.

ÐHeadlights
1. Open the hood. Unplug the connec-
tor. Remove the rubber cover.
If the connector is tight, wiggle it.2. Release the bulb retaining spring and remove the bulb. Install a new
bulb and the bulb retaining spring.
To install a bulb, align the tabs of the
bulb with the cutouts of the mounting
hole.3. Install the rubber cover with the ºTOPº mark upward and snuggle on
the boss. Then insert the connector.
Make sure the rubber cover fits snugly on
the connector and the headlight body.
Aiming is not necessary after replacing
the bulb. When aiming adjustment is nec-
essary, contact your Toyota dealer.
