brake TOYOTA 4RUNNER 1998 Owner's Manual

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.

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.

4RUNNER (1998)
CAUTION
Before driving, be sure the park-
ing brake is fully released and
the parking brake reminder light
is off.
Cruise control
The cruise control allows you to
cruise the vehicle at a desired
speed over 40 km/h (25 mph) even
with your foot off the accelerator
pedal.
Your cruising speed can be maintained
up or down grades within the limits of
engine performance, although a slight
speed change may occur when driving
up or down the grades. On steeper
hills, a greater s peed change will oc-
cur so it is better to drive without the
cruise control.
CAUTION
To help maintain maximum con-
trol of your vehicle, do not use
the cruise control when driving
in heavy or varying traffic, or
on slippery (rainy, icy or snow-
covered) or winding roads.
Avoid vehicle speed increases
when driving downhill. If the ve-
hicle speed is too fast in rela-
tion to the cruise control set
speed, cancel the cruise control
then downshift the transmission
to use engine braking to slow down.

4RUNNER (1998)
SETTING AT A DESIRED SPEED
On vehicles with automatic transmis-
sion, the transmission must be in ºDº
before you set the cruise control
speed.
Bring your vehicle to the desired
speed, push the lever down in the
ºSET/COASTº direction and release it.
This sets the vehicle at that speed. If
the speed is not satisfactory, tap the
lever up for a faster speed, or tap it
down for a slower speed. Each tap
changes the set speed by 1.6 km/h
(1.0 mph). You can now take your foot
off the accelerator pedal. If you need accelerationÐfor example,
when passingÐdepress the accelera-
tor pedal enough for the vehicle to
exceed the set speed. When you re-
lease it, the vehicle will return to the
speed set prior to the acceleration.
CAUTION
For manual transmission:
While driving with the cruise con-
trol on, do not shift to neutral
without depressing the clutch
pedal, as this may cause engine
racing or overrevving.
CANCELLING THE PRESET SPEED
You can cancel the preset speed by:a. Pulling the lever in the ºCANCELº
direction and releasing it.
b. Depressing the brake pedal.
c. Depressing the clutch pedal (manu- al transmission).
If the vehicle speed falls below about
40 km/h (25 mph), the preset speed
will automatically cancel out.
If the vehicle speed drops 16 km/h
(10 mph) below the preset speed, the
preset speed will also automatically
cancel out.

4RUNNER (1998)
If the preset speed automatically can-
cels out other than for the above
cases, have your vehicle checked by
your Toyota dealer at the earliest op-
portunity.
RESETTING AT A FASTER SPEED
Push the lever up in the ºRES/ACCº
direction and hold it. Release the le-
ver when the desired speed is at-
tained. While the lever is held up, the
vehicle will gradually gain speed.
However, a faster way to reset is to
accelerate the vehicle and then push
the lever down in the ºSET/COASTº
direction.
RESETTING AT A SLOWER SPEED
Push the lever down in the ºSET/
COASTº direction and hold it. Release
the lever when the desired speed is
attained. While the lever is held down,
the vehicle speed will gradually de-
crease.
However, a faster way to reset is to
depress the brake pedal and then
push the lever down in the ºSET/
COASTº direction. On vehicles with automatic transmis-
sion, even if you turn off the overdrive
switch, with the cruise control on, en-
gine braking will not be applied be-
cause the cruise control is not can-
celled. To decrease the vehicle speed,
reset to a slower speed with the
cruise control lever or depress the
brake pedal. If you use the brake ped-
al, cruise control is cancelled.
RESUMING THE PRESET SPEED
If the preset speed is cancelled by
pulling the control lever or by de-
pressing the brake pedal or clutch
pedal, pushing the lever up in the
ºRES/ACCº direction will restore the
speed set prior to cancellation.
However, once the vehicle speed falls
below about 40 km/h (25 mph), the
preset speed will not be resumed.
CRUISE CONTROL FAILURE WARN-
ING
If the ºCRUISEº indicator light in the
instrument cluster flashes when using
the cruise control, press the ºCRUISE
ON- OFFº button to turn the system
off and then press it again to turn it on.If any of the following conditions then
occurs, there is some trouble in the
cruise control system.
The indicator light does not comeon.
The indicator light flashes again.
The indicator light goes out after it
comes on.
If this is the case, contact your Toyo-
ta dealer and have your vehicle in-
spected.

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.

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.
Brake pad wear limit indica-
tors

4RUNNER (1998)
The brake pad wear limit indicators
on your disc brakes give a warning
noise when the brake pads are
worn to where replacement is re-
quired.
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 rotor damage can result if
the pads are not replaced when nec-
essary. Luggage stowage pr
ecau-
tions
When stowing luggage or cargo in the
vehicle, observe the following:
Put luggage or cargo in the lug-
gage compartment when at all pos-
sible. Be sure all items are se-
cured in place.
Be careful to keep the vehicle bal-
anced. Locating the weight as far
forward as possible helps maintain
balance.
For better fuel economy, do not
carry unneeded weight.
CAUTION
To prevent luggage or packages
from sliding forward during
braking, do not stack anything
in the luggage compartment
higher than the seatbacks. Keep
luggage or packages low, as
close to the floor as possible.
Never allow anyone to ride in
the luggage compartment. 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 colli-
sion.
