1998 TOYOTA 4RUNNER warning light

4RUNNER (1998)
To lock the rear differential, push
the switch.
Be sure to stop the wheels before
locking the differential.
Vehicles with manual transmis-
sion'For easy locking, depress the
clutch pedal, push the lock switch and
slowly release the clutch pedal.
The indicator light will blink when the
switch is turned on. Wait a few se-
conds for the system to complete op-
eration. After the differential is locked,
the light will stop blinking and remain on. 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

Do not lock the differential until
the wheels have stopped spin-
ning. Otherwise, the vehicle
may move in an unexpected
direction when the differential
lock is engaged, resulting in an
accident. This may also lead to
possible damage to differential
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
vehicle moves out.

Your engine is fitted with twin
ground electrode spark plugs.
NOTICE
Use only twin ground electrode
spark plugs for your engine per-formance.
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 hard-
er to press, and your stopping dis-
tance 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 vacu-
um to power- assist the brakes. If the
engine should quit while you are driv-
ing, you can bring the vehicle to a
stop with normal pedal pressure.
There is enough reserve vacuum for
one or two stopsÐbut no more!
CAUTION

Do not pump the brake pedal if
the engine stalls. Each push on
the pedal uses up your vacuum
reserve.

4RUNNER (1998)
Even if the power assist is
completely lost, the brakes will
still work. But you will have to
push the pedal hardÐmuch
harder than normal. And your
braking distance will be longer.
ANTI- LOCK BRAKE SYSTEM
(with ºABSº warning light)
The anti- lock brake system is de-
signed 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 per-
formance of the vehicle under these
circumstances.
The anti- lock brake system becomes
operative after the vehicle has accel-
erated to a speed in excess of
approximately 10 km/h (6 mph). It
stops operating when the vehicle de-
celerates to a speed below approxi-
mately 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 reduced braking per-
formance.
The brake pedal pulsation caused by
the anti- lock brake system may indi-
cate hazardous road surface condi-
tions. Although the anti- lock brake
system assists in providing 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
vehicle:
Braking capab ility is dependent on
tire friction with the road surface.
Even though the anti- lock brake
system is operating, a driver can-
not maintain full control on certain
slippery road surfaces, when cor-
nering 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
require a longer stopping distance in
the following cases:
Driving on rough, gravel or snow-
covered roads.
Driving with tire chains installed.
Driving on roads where the road
surface is pitted or has other differ-
ences in surface height.
CAUTION
Do not use tires other than the
manufacturer 's designated tires,
and do not mix tires or wheels of
different sizes. You may prevent
the antilock 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 about 3 seconds, the light will
go off.

4RUNNER (1998)
When the light is on with the rear
differential locked, it indicates the
anti- lock brake system will not oper-
ate.
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
described 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 light comes on while driving. 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 assist-
ing 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
possible.

Tire surface and wheel nuts
Check the tires carefully for cuts,
damage or excessive wear. See Chap-
ter 7- 2 for additional information.
When checking the tires, make sure
no nuts are missing, and check the
nuts for looseness. Tighten them if
necessary.
Tire rotation
Rotate the tires every 12000 km (7500
miles). See Chapter 7- 2 for additional
information.
Fluid leaks
Check underneath for leaking fuel, oil,
water or other fluid after the vehicle
has been parked for a while. If you
smell fuel fumes or notice any leak,
have the cause found and corrected
immediately.
Doors and engine hood
Check that all doors including back
door operate smoothly and all latches
lock securely. Make sure the engine
hood secondary latch secures the
hood from opening when the primary
latch is released. INSIDE THE VEHICLE
Items listed below should be
checked regularly, e.g. while per-
forming periodic services, cleaning
the vehicle, etc.
Lights
Make sure the headlights, stop lights,
tail lights, turn signal lights, and other
lights are all working. Check headlight
aim.
Service reminder indicators and
warning buzzers
Check that all service reminder indica-
tors and warning buzzers function
properly.
Steering wheel
Check that it has the specified free-
play. Be alert for changes in steering
condition, such as hard steering or
strange noise.
Seats
Check that all seat controls such as
seat adjusters, seatback recliner, etc.
operate smoothly and that all latches
lock securely in any position. Check
that the head restraint move up and
down smoothly and that the locks hold
securely in any latched position. For
folding- down rear seatbacks, swing- up
rear seat cushions and detachable
temporary third seat, check that the
latches lock securely.Seat belts
Check that the seat belt system such
as buckles, retractors and anchors op-
erate properly and smoothly. Make
sure the belt webbing is not cut,
frayed, worn or damaged.
Accelerator pedal
Check the pedal for smooth operation
and uneven pedal effort or catching.
Clutch pedal
Check the pedal for smooth operation.
Brake pedal
Check the pedal for smooth operation
and that the pedal has the proper
clearance. Check the brake booster
function.
Brakes
At a safe place, check that the brakes
do not pull to one side when applied.
Parking brake
Check that the lever has the proper
travel and that, on a safe incline, your
vehicle is held securely with only the
parking brake applied.
