Use the front drive control lever to se-
lect the following transfer modes.
ºH2º (high speed position, two- wheel
drive): Lever at ºH2º
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 ºH4º
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(c) Shifting procedure (lever type)º
for further instructions.

Use the front drive control lever and
º4WDº button to select the transfer and
center differential modes.
ºH2º mode (high speed position, two-
wheel drive):
Lever at ºH2´H4º, º4WDº
button left out
Use this for normal driving on dry hard-
surfaced roads. This position gives greater
economy, quietest ride and least wear and
better vehicle control.
ºH4º mode (high speed position, four-
wheel drive, center differential un-
locked): Lever at ºH2´H4º, º4WDº button
pushed in
Use this for normal driving on all types of
roads, from dry hard- surfaced roads to
wet, icy or snow- covered roads. This
position provides greater traction than
two- wheel drive. ºH4Lº mode (high speed position, four-
wheel drive, center differential locked):
Lever at ºH4Lº
Use this for greater traction when you
experience a loss of power, such as
wheel slipping, in the ºH2´H4º (four- wheel
drive) mode.
ºNº mode (neutral position):
Lever at
ºNº
No power is delivered to the wheels. The
vehicle must be stopped.
ºL4Lº mode (low speed position, four-
wheel drive, center differential locked):
Lever at ºL4Lº
Use this for maximum power and traction.
Use ºL4Lº mode for hard pu lling in situa-
tions the vehicle cannot negotiate even in
the ºH4Lº mode.
The indicator shows which transfer and
center differential mode the vehicle is in.
See º(c) Shifting procedureº for further in-
structions.
Steel wheels
Aluminum wheels (b) A.D.D. (automatic
disconnecting differential)

4RUNNER ()107
The A.D.D. can be engaged or disen-
gaged by the shifting operations des-
cribed in º(c) Shifting procedureº.
You should drive in four- wheel drive for
at least 16 km (10 miles) each month.
This will assure that the front drive com-
ponents are lubricated.

To shift from ºL4Lº to ºH4Lº,
stop the
vehicle and put the transmission in ºNº.
With your foot holding down the brake
pedal, move the front drive control lever.
NOTICE
Do not drive on a dry paved surface

Rear differential lock system
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.
Before using the rear differential lock sys-
tem, first shift the front drive control into
ºL4º to see if it works. If this has no
effect, additionally use the rear differential
lock system.
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.

4RUNNER ()111
To lock the rear differential, push the
switch.
Be sure to stop the wheels before locking
the differential.
Vehicles with manual transmissionÐFor
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 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. 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 igni-
tion 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 up the lever. For better hold-
ing 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.
CAUTION
Before driving, be sure the parking
brake is fully released and the park-
ing 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 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.
