(f) Malfunction Indicator Lamp
This lamp comes on in the following
cases.
a. The fuel tank is completely empty. (See
ºFuel gaugeº in Chapter 1- 5 for instruc-
tions.)
b. The fuel tank cap is not tightened se-
curely. (See ºFuel tank capº in Chapter
1- 2 for instructions.)
c. There is a problem somewhere in your
engine or automatic transmission electrical
system.
If it comes on while you are driving in
case c, have your vehicle checked/re-
paired by your Toyota dealer as soon as
possible.
(g) Low Fuel Level Warning Light
This light comes on when the fuel level
in the tank becomes nearly empty. Fill up
the tank as soon as possible.
On inclines or curves, due to the move-
ment of fuel in the tank, the low fuel level
warning light may come on earlier than
usual.
(h) ºABSº Warning Light
This light warns that there is a problem
somewhere in your anti- lock brake sys-
tem.
If the light comes on while you are driv-
ing, have your vehicle checked by your
Toyota dealer as soon as possible.
The light will come on when the ignition
key is turned to the ºONº position. After
a few seconds, the light will go off.
When the ºABSº warning light is on (and
the brake system warning light is off), the
brake system operates conventionally but
anti- lock brake system is not assisting
brake performance so that the wheels can
lock- up during sudden braking or braking
on slippery road surfaces.
Vehicles with rear differential lock sys-
temÐ
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.
(i) Open Door Warning Light
This light remains on until all the doors
and back door are completely closed.(j) SRS Airbag Warning Light
This light will come on when the igni-
tion key is turned to the ºACCº or
ºONº position. After about 6 seconds,
the light will go off. This means the
system of the airbag and front seat belt
pretensioner are operating properly.
The warning light system monitors the air-
bag sensor assembly, front airbag sen-
sors, seat belt pretensioner assemblies,
inflators, warning light, interconnecting wir-
ing and power sources.
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 when the
ignition key is turned to the ºACCº or
ºONº position or remains on.
The light comes on or flashes while
driving.

ºSTARTºÐStarter motor on. The key
will return to the ºONº position when
released.
For starting tips, see Part 3.
ºONºÐEngine on and all accessories on.
This is the normal driving position.
ºACCºÐAccessories such as the radio
operate, but the engine is off.
If you leave the key in the ºACCº or
ºLOCKº position and open the driver's
door, a buzzer will remind you to remove
the key.
ºLOCKºÐEngine is off and the steering
wheel is locked. The key can be re-
moved only at this position. Vehicles with manual transmissionÐ
You must push in the key to turn the key
from ºACCº to the ºLOCKº position.
Vehicles with automatic transmissionÐ
You must shift the selector lever into the
ºPº position before turning the key from
ºACCº to the ºLOCKº position.
Vehicles with engine immobiliser systemÐ
Once you remove the key, the engine im-
mobiliser system is automatically set. (See
ºEngine immobiliser systemº in C
hapter
1- 2.)
When starting the engine, the key may
seem stuck at the ºLOCKº position. To
free it, first be sure the key is pushed all
the way in, and then rock the steering
wheel slightly while turning the key gently.
CAUTION
For manual transmission:
Never remove the key when the ve-
hicle is moving, as this will lock the
steering wheel and result in loss of
steering control.

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.

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
in ºH4Lº or ºL4Lº mode. This maydamage the locking mechanism andthe drive system.
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.

Avoid high speeds on wet roads. The
anti- lock brake system cannot elimi-
nate 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 r equire a longer
stopping distance in the following cases:
Driving on rough, gravel or snow- cov-
ered roads.
Driving with tire chains installed.
Driving on roads where the road sur-
face is pitted or has other differences
in surface height.
CAUTION
Do not use tires other than the
manufacturer 's designated tires, and
do not mix tires or wheels of differ-
ent sizes. You may prevent the anti-
lock 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.
