TOYOTA TACOMA 1998 Owners Manual

'98 Tacoma (U)91
Use the front drive control lever and
º4WDº button to select the following
transfer modes.
ºH2º (high speed position, two-wheel
drive): Lever at ºHº, º4WDº button left out
Use this for normal driving on dry hard-
surfaced roads. This position gives greater
economy, quietest ride and least wear.
ºH4º (high speed position, four-wheel
drive): Lever at ºHº, º4WDº button pushed
in.
Use this for normal driving on wet, icy or
snow-covered roads. This position pro-
vides greater traction than two-wheel
drive. ºNº (neutral position):
Lever at ºNº
No power is delivered to the wheels. The
vehicle must be stopped.
ºL4º (low speed position, four-wheel
drive): Lever at ºL4º
Use this for maximum power and traction.
Use ºL4º for climbing or descending steep
hills, off-road driving, and hard pulling in
sand, mud or deep snow.
The four-wheel drive indicator light comes
on when the ºH4º, ºNº or ºL4º mode is
selected.
See º(d) Shifting procedure (lever/button
type)º for further instructions. (b) Free-wheeling hubsTo engage the free-wheeling hubs, turn
the hubs to ºLOCKº. To disengage, turn
the hubs to ºFREEº.
Make sure the triangle mark on the hub
aligns with the other one at the side you
wish to set.
Setting the free-wheeling hubs in ºFREEº
allows you to disengage the front axle and
driveshaft so that they are not revolving.
This reduces noise and wear when the
vehicle is in two-wheel drive.
You should drive with the hubs in ºLOCKº
for at least 16 km (10 miles) each month.
This will assure that the front drive com-
ponents are lubricated.

The rear differential lock system is pro-
vided for use only when wheel spinning
occurs in a ditch or on a slippery or
ragged surface.
This differential lock system is effective in
case one of the rear wheels is spinning.
Except for Pre Runner models
'
Before using the rear differential lock sys-
tem, first shift the front drive control into
ºL4º with the free-wheeling hubs engaged
to see if it works. If this has no effect,
additionally use the rear differential lock
system.

'98 Tacoma (U)97
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.

'98 Tacoma (U)

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 differen-
tial lock switch on.
Parking brake
When parking, firmly apply the parking
brake to avoid inadvertent creeping.
To set: Pull out on the lever. For better
holding power, first depress the brake
pedal and hold it while setting the parking
brake.
To release: Press the lock release button,
turn the lever, and push it in.
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.
CAUTION
Before driving, be sure the parking
brake is fully released and the park-
ing brake reminder light is off.

'98 Tacoma (U)99
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 h
ills, a
greater speed change will occur so it is
better to drive without the cruise control.
CAUTION
To help maintain maximum control
of your vehicle, do not use the
cruise control when driving in
heavy or varying traffic, or on slip-
pery (rainy, icy or snow-covered) or
winding roads.
Avoid vehicle speed increases when
driving downhill. If the vehicle
speed is too fast in relation to the
cruise control set speed, cancel the
cruise control then downshift the
transmission to use engine braking
to slow down.TURNING ON THE SYSTEM
To operate the cruise control, press the
ºCRUISE ON-OFFº button. This turns the
system on. The indicator light in the
instrument panel shows that you can now
set the vehicle at a desired cruising
speed. Another press will turn the system
completely off.
CAUTION
To avoid accidental cruise control en-
gagement, keep the ºCRUISE ON-
OFFº switch off when not using the
cruise control.
SETTING AT A DESIRED SPEED
On vehicles with automatic transmission,
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 ve-
hicle 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.

'98 Tacoma (U)
100
If you need acceleration±for example,
when passing±depress the accelerator
pedal enough for the vehicle to exceed
the set speed. When you release it, the
vehicle will return to the speed set prior
to the acceleration.
CAUTION
For manual transmission:
While driving with the cruise control
on, do not shift to neutral without
depressing the clutch pedal, as this
may cause engine racing or overrev-
ving.
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 (manual transmission)
If the vehicle speed falls below about 40
km/h (25 mph), the preset speed will auto-
matically cancel out.
If the vehicle speed drops 16 km/h (10
mph) below the preset speed, the preset
speed will also automatically cancel out.
If the preset speed automatically cancels
out other than for the above cases, have
your vehicle checked by your Toyota deal-
er at the earliest opportunity.
RESETTING AT A FASTER SPEED
Push the lever up in the ºRES/ACCº direc-
tion and hold it. Release the lever when
the desired speed is attained. While the
lever is held up, the vehicle will gradually
gain speed.
However, a faster way to reset is to ac-
celerate 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 decrease.
However, a faster way to reset is to de-
press the brake pedal and then push the
lever down in the ºSET/COASTº direction.
On vehicles with automatic transmission,
even if you turn off the overdrive switch
with the cruise control on, engine braking
will not be applied because the cruise
control is not cancelled. 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
pedal, cruise control is cancelled.
RESUMING THE PRESET SPEED
If the preset speed is cancelled by pu
lling
the control lever or by depressing 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 be-
low about 40 km/h (25 mph), the preset
speed will not be resumed.
