1998 TOYOTA 4RUNNER differential

4RUNNER (1998)
For easy unlocking, slightly turn the
steering wheel in either direction while
the vehicle is in motion.
When the differential lock is disen-
gaged, the indicator light will go out. 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.
To check the indicator bulb, turn the
ignition key to the ºONº position, but
do not start the engine.
CAUTION
Do not keep driving with the dif-
ferential lock switch on.
Parking brake
When parking, firmly apply the
parking brake to avoid inadvertent
creeping.
To set: Pull up the lever. For better
holding power, first depress the brake
pedal and hold it while setting the
brake.
To release: Pull up the lever slightly,
press the thumb button, and lower.To remind you that the parking brake
is set, the parking brake reminder
light in the instrument panel remains
on until you release the parking brake.

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.

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.

The driver and all passengers
should fasten their seat belts
whenever the vehicle is moving.
NOTICE
If driving through water, such
as when crossing shallowstreams, first check the depth of the water and the bottom of
the river bed for firmness. Driveslowly and avoid deep water.
Take all necessary safety mea-
sures to ensure that water dam-age to the engine or other com- ponents does not occur.
Water entering the engine airintake will cause severe engine
damage.
Water can wash the grease fromwheel bearings, causing rustingand premature failure, and mayalso enter the differentials,
transmission and transfer case,reducing the gear oil's lubrica-ting qualities.
Sand and mud that has accum-
lated in brake drums andaround brake discs may affectbraking efficiency and may dam-
age brake system components.
Always perform a maintenanceinspection after each day of
off- road driving that has takenyou through rough terrain,sand, mud, or water. For sche-
duled maintenance information,refer to the separate ºOwner's Manual Supplement/Maintenance
Scheduleº.
Winter driving tips
Make sure you have ethylene- glycol
antifreeze in the radiator.
NOTICE
Do not use alcohol type anti-freeze.
Check the condition of the battery
and cables.
Cold temperatures reduce the capacity
of any battery, so it must be in top
shape to provide enough power for
winter starting. Chapter 7- 3 tells you
how to visually inspect the battery.
Your Toyota dealer and most service
stations will be pleased to check the
level of charge.
Make sure the engine oil viscosity
is suitable for the cold weather.
See Chapter 7- 2 for recommended
viscosity. Leaving a heavy summer oil
in your vehicle during winter months
may cause harder starting. If you are
not sure about which oil to use, call
your Toyota dealerÐhe will be pleased
to help.
Keep the door locks from freezing.
Squirt lock de- icer or glycerine into
the locks to keep them from freezing.
To open a frozen lock, try heating the
key before inserting it.

4RUNNER (1998)
A safety chain must always be
used between the towing vehicle
and the trailer. Leave sufficient
slack in the chain for turns. The
chain should cross under the
trailer tongue to prevent the
tongue from dropping to the
ground in case it becomes dam-
aged or separated. For correct
safety chain procedures, follow
the hitch or trailer manufactur-
er 's recommendations.
CAUTION
If the total trailer weight ex-
ceeds 453 kg (1000 lb.), trailer
brakes are required .
Never tap into your vehicle's
hydraulic system as it would
lower its braking effectiveness .
Never tow a trailer without us-
ing a safety chain securely atta-
ched to both the trailer and the
vehicle. If damage occurs to the
coupling unit or hitch ball,
there is danger of the trailer
wandering over into another
lane.
TIRES
Ensure that your vehicle's tires are
properly inflated. See Chapter 7- 2
for instructions.
The trailer tires should be inflated
to the pressure recommended by
the trailer manufacturer in respect
to the total trailer weight.
TRAILER LIGHTS Trailer lights must comply with fed-
eral, state/provincial and local re-
gulations. See your local recre-
ational vehicle dealer or rental
agency for the correct type of wir-
ing and relays for your trailer.
Check for correct operation of the
turn signals and stop lights each
time you hitch up. Direct splicing
may damage your vehicle's electri-
cal system and cause a malfunc-
tion of your lights.
BREAK- IN SCHEDULE Toyota recommends that you do
not tow a trailer with a new vehicle
or a vehicle with any new power
train component (engine, transmis-
sion, differential, wheel bearing,
etc.) for the first 800 km (500
miles) of driving. MAINTENANCE
If you tow a trailer, your vehicle
will require more frequent
maintenance due to the additional
load. For this information, please
refer to the scheduled maintenance
information in the ºOwner 's Manual
Supplement/Maintenance Scheduleº.
Retighten all fixing bolts of the
towing ball and bracket after
approximately 1000 km (600 miles)
of trailer driving.
PRE- TOWING SAFETY CHECK
Check that your vehicle remains
level when a loaded or unloaded
trailer is hitched. Do not drive if
the vehicle has an abnormal nose-
up or nose- down condition, and
check for improper tongue load,
overload, worn suspension or other
possible causes.
Make sure the trailer cargo is se-
curely loaded so that it cannot
shift.
Check that your rear view mirrors
conform to any applicable federal,
state/provincial or local regulation.
If not, install the rear view mirrors
required for towing purpose.
