The engine ignition will continue to oper-
ate, however, until the battery is dis-
charged. Turn off the air conditioning,
blower, radio, e
ct., and drive directly to the
nearest Toyota dealer or repair shop.
NOTICE
Do not continue driving if the engine drive belt is broken or loose.
(d) Low Oil Pressure Warning Light
This light warns that the engine oil pres-
sure is too low.
If it flickers or stays on while you are driv-
ing, pull off the road to a safe place and
stop the engine immediately. Call a Toyo-
ta dealer or qualified repair shop for assis- tance.
The light may occasionally flicker when
the engine is idling or it may come on brief-
ly after a hard stop. There is no cause for concern if it then goes out when the en-
gine is accelerated slightly.
The light may come on when the oil level
is extremely low. It is not designed to indi- cate low oil level, and the oil level must bechecked using the level dipstick.
NOTICE
Do not drive the vehicle with the warning light onÐeven for one
block. It may ruin the engine.
(e) 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. (f) Malfunction Indicator Lamp
This lamp comes on in the following cases.
a. The fuel tank is completely empty. (See Fuel gaugeº in Chapter 1-5 for in- structions.)
b. The fuel tank cap is not tightened se-
curely. (See Fuel tank capº in Chapter
1-2 for instructions.)
c. There is a problem somewhere in your
engine or automatic transmission electri- cal system.
If it comes on while you are driving in case
c, have your vehicle checked/repaired by
your Toyota dealer as soon as possible. (g) ABSº 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 driving,
have your vehicle checked by your T
oyota
dealer as soon as possible.
The light will come on when the ignition
key is turned to the ONº position. After
about 3 seconds, the light will go off. When the ABSº warning light is on (and
the brake system warning light is off), thebrake system operates conventionally but
anti-lock brake system is not assistingbrake 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 op-
erate when the rear differential is locked.
It is normal operation for the ABSº warn-
ing light to be on at this time.

ONº ÐEngine on and all accessories on.
This is the normal driving position. ACCº - Accessories such as the ra-
dio operate, but the engine is off.
If you leave the key in the ACCº or
LOCKº position and open the driver's
door, a buzzer will remind you to remove
the key.
LOCKº ÐEngine is off and the steer-
ing wheel is locked. The key can be re-
moved only at this position. You must push in the key to turn the key
from ACCº to the LOCKº position. On
vehicles with an automatic transmission,
the selector lever must be put in the Pº
position before pushing the key. When starting the engine, the key may
seem stuck at the LOCKº 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.For manual transmission:
Never remove the key when the
vehicle is moving, as this will lock
the steering wheel and result in loss
of steering control. CAUTION
!
NOTICE
Do not leave the key in the ONº position if the engine is not running.
The battery will discharge and the ignition could be damaged.

Steel wheels
Aluminum wheelsThe A.D.D. can be engaged or disen-
gaged by the shifting operations de-
scribed in (d) 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 compo- nents are lubricated.
SHIFTING BETWEEN H2º AND H4º With free-wheeling hubs
To shift from H2º to H4º
, move the
front drive control lever. Also, engage both the free-wheeling hubs.
This can be done when the vehicle is stopped, or moving straight ahead at
speeds of 40 km/h (25 mph) or less. You need not depress the clutch pedal. If you
have trouble shifting, depress or releasethe accelerator pedal momentarily while
pushing the front drive control lever.
Never move the front drive control
lever if wheels are slipping. Stop
the slipping or spinning before shifting.
Never drive with only one hub en- gaged. CAUTION
!
To shift from H4º to H2º , simply move
the front drive control lever. Also, disen-
gage both the free-wheeling hubs for con-
tinued H2º use.
This can be done at any vehicle speed.
You Need not depress the clutch pedal.

86To shift from H4º to H2º
, push the
4WDº button again to turn it off. This can be done at any vehicle speed.
If the indicator light does not go off when you shift the transfer into H2º, drive
straight ahead while accelerating or de-celerating, or drive in reverse. SHIFTING BETWEEN H2º OR H4º AND L4º
To shift from H2º or H4º to L4º
, stop
the vehicle and put the transmission in
Nº. With your foot holding down the brake
pedal, move the front drive control lever.
To shift from L4º to H2º or H4º , stop
the vehicle and put the transmission in
Nº. With your foot holding down the brake pedal, move the front drive control
lever. When the 4WDº button is pushed in, the transfer shifts into H4º; when the button is left out, the transfer shifts intoH2º.
If the indicator light does not go off when you shift the transfer into H2º, drive
straight ahead while accelerating or de- celerating, or drive in reverse.
The rear differential lock system is
provided for use only when wheel
spinning occurs in a ditch or on a slip-
pery 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 L4º with the free-wheeling hubs engaged
to see if it works. If this has no ef fect, addi-
tionally use the rear differential lock sys-tem.

87
Do not use the rear differential lock
in the conditions other than above.
Large steering effort and careful
cornering control will be required.CAUTION
!
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 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. After
the differential is locked, the light will stop
blinking and remain on.
The anti-lock brake system does not op-
erate when the rear differential is locked.
It is normal operation for the ABSº warn-
ing light to be on at this time.
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 en-
gaged, resulting in an accident.
This may also lead to possible
damage to differential lock com-
ponent parts.
Do not drive over 8 km/h (5 mph)
when the differential is locked. CAUTION
!
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 L4º. Never forget to turn off the switch after us-
ing this feature.

88To check the indicator bulb, turn the igni-
tion key to the ONº position, but do not
start the engine.
Do not keep driving with the
differential lock switch on.
CAUTION
!
When parking, firmly apply the park-
ing brake to avoid inadvertent creep- ing.
To set: Pull out on the lever. For better
holding power, first depress the brake
pedal and hold it while setting the parking brake.

Effective way to press the ABSº 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 pumpthe brake. This will result in reduced
braking performance.
The brake pedal pulsation caused by the
anti-lock brake system may indicate haz- ardous road surface conditions. Althoughthe anti-lock brake system assists in pro-
viding 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 sys-
tem is operating, a driver cannot main- tain full control on certain slippery road
surfaces, when cornering at highspeeds, or in violent maneuvers.
Avoid high speeds on wet roads. The
anti-lock brake system cannot elimi-
nate the risk of hydroplaning and lossof tire friction. Always maintain a safe distance from the
vehicle in
front of you. Compared with ve-
hicles 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-cov-
ered roads.
Driving with tire chains installed.
Driving on roads where the road sur-
face is pitted or has other differencesin 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 antilockbrake system from operating at fulleffictiveness.

ABSº warning light
This light comes on when the ignition key is turned to the ONº position. After about
3 seconds, the light will go off.
If any 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 de-
scribed above, or remains on.
The light comes on while driving.
Vehicles with rear differential lock sys- temÐ The light comes on while driving with
the rear differential unlocked.
The light does not come on with the
rear differential locked.
The system comes into operation with
the rear differential locked. Even if the anti-lock brake system
should
fail, the brake system will still operate con-
ventionally. However, when the `ABS''
warning light is on (and the brake system
warning light is off), the anti-lock brake
system is not assisting brake perfor-mance so that the wheels can lock-up
during sudden braking or braking on slip-
pery road surfaces. Have your vehicle
checked by your Toyota dealer as soon as
possible
The brake pads wear limit indicators
on your disc brakes give a warning
noise w hen the brake pads are worn to
where replacement is required.
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 ro-
tor damage can result if the pads are not
replaced when necessary.

CAUTION
Always observe the following
precautions to minimize the risk of
serious per sonal injury or damage to
your vehicle: Drive carefully when off the road.
Do not take unnecessary risks by
driving in dangerous places.
Do not grip the steering wheel
spokes when driving off-road. A
bad bump could jerk the wheel and
injure your hands. Keep both
hands and especially your thumbson the outside of the rim.
Always check your brakes for effec-
tiveness immediately after driving
in sand, mud, water or snow.
After driving through tall grass,
mud, rock, sand, rivers, etc., check
that there is no grass, bush, paper,
rags, stone, sand etc. adhering or
trapped on the underbody. Clear off
any such matter from the under-
body. If the vehicle is used with these materials trapped or adher-
ing to the underbody, a breakdown
or fire could occur.! The driver and all passengers
should fasten their seat belts
whenever the vehicle is moving.

If driving through water, such as when crossing shallow streams,
first check the depth of the waterand the bottom of the river bed for
firmness. Drive slowly and avoiddeep water.
Take all necessary safety mea-sures to ensure that damage to the
engine or other components does not occur.
Water entering the engine air in-take will cause severe engine dam-
age. Water can wash the grease from
wheel bearings, causing rustingand premature failure, and may
also enter the differential, trans-mission and transfer case, reduc-
ing the gear oil's lubricating quali-ties.
Sand and mud that has accumu-lated in brake drums and around
brake discs may affect braking ef-ficiency and may damage brake
system components.
NOTICE
Always perform a maintenance in-spection after each day of off-
road driving that has taken youthrough rough terrain, sand, mud,
or water. For scheduled mainte- nance information, refer to the
separate Owner's Manual Sup-plement/Maintenance Scheduleº.
