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 releasethe 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.
To 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 differ- ential lock switch on. CAUTION
!

81
When parking, firmly apply the park-
ing brake to avoid inadvertent creep- ing.
To set: Pull up the lever.
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 re-lease the parking brake.
Before driving, be sure the parking brake is fully released and the park-
ing brake reminder light is off. CAUTION
! The cruise control allows you to cruise
the vehicle at a desired speed over 40 km/h (25 mph) even with your foot offthe 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 speed change will occur so it is
better to drive without the cruise control.

To help maintain maximum con-
trol 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 ve-
hicle speed is too fast in relation to
the cruise control set speed, can-
cel the cruise control then down-
shift the transmission to use en-
gine braking to slow down. CAUTION
!TURNING ON THE SYSTEM
To operate the cruise control, press the
CRUISE ON-OFFº button. This turns thesystem on. The indicator light in the instru-
ment panel shows that you can now set
the vehicle at a desired cruising speed.
Another press will turn the system com-
pletely off.
To avoid accidental cruise control
engagement, keep the CRUISE
ON-OFFº
switch off when not using
the cruise control. CAUTION

82
SETTING AT A DESIRED SPEED
On vehicles with automatic transmission,
the transmission must be in Dº beforeyou set the cruise control speed.
Bring your vehicle to the desired speed, push the lever down in the SET/COASTº
direction and release it. This sets the ve-
hicle at that speed. If the speed is not sat-
isfactory, 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 accelerator
pedal
enough for the vehicle to exceed the
set speed. When you release it, the ve-
hicle will return to the speed set prior to the
acceleration.
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. CAUTION
!
CANCELLING THE PRESET SPEED
You can cancel the preset speed by:
a. Pulling the lever in the CANCELº di- rection 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 presetspeed 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 RES/ACCº direc-
tion and hold it. Release the lever when
the desired speed is attained. While the
lever is held up, the vehicle will graduallygain speed.
However, a faster way to reset is to accel-
erate the vehicle and then push the lever down in the SET/COASTº direction.
RESETTING AT A SLOWER SPEED Push the lever down in the SET/COASTº
direction and hold it. Release the lever
when the desired speed is attained. While
the lever is held down, the vehicle speedwill gradually decrease.
However, a faster way to reset is to de- press the brake pedal and then push the
lever down in the SET/COASTº direction.

83
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 con-
trol is not cancelled. To decrease the ve-
hicle 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 pulling
the control lever or by depressing the
brake pedal or clutch pedal, pushing the
lever up in the RES/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.
CRUISE CONTROL FAILURE WARN- ING
If the CRUISEº indicator light in the in-
strument cluster flashes when using the
cruise control, press the CRUISE ON-
OFFº button to turn the system off and then press it again to turn it on. If any of the following conditions then oc-
curs, there is some trouble in the cruise control system.
The indicator light does not come on.
The indicator light flashes again.
The indicator light goes out after it
comes on.
If this is the case, contact your Toyota
dealer and have your vehicle inspected.
To crank the engine without depress- ing the clutch pedal, push the switch
with the ignition on.
The switch stays on as long as the ignition
is on. And it will automatically turn off
when the ignition is off.
This switch cancels the clutch start sys-
tem, which is designed to keep the starter
motor from operating if the clutch pedal is
not depressed all the way down.
The switch allows the vehicle to be driven
out of difficult situations by cranking the
engine with the clutch engaged.
Clutch start cancel switch (four-wheel drive modelswith manual transmission)

84Never use the switch for normal engine
starting. Be sure to follow the sta
rting pro-
cedure instructed in How to start the en- gineº in Part 3.

Suspension and chassis
Types of tires
This vehicle is one of the class of ve-
hicles which have higher ground
clearance and narrower tread in rela-
tion to the height of their center of
gravity to make them capable of per-forming in a wide variety of off-road applications. Specific design charac-
teristics
give it a higher center of gravi-
ty than ordinary cars. An advantage of
the higher ground clearance is a better
view of the road allowing you to antici-
pate problems. It is not designed for
cornering at the same speeds as con-
ventional two-wheel drive vehicles
any more than low-slung sports cars
are designed to perform satisfactorilyunder off-road conditions.
CAUTION!
Always observe the following pre-
cautions to minimize the risk of se-
rious personal injury or damage toyour vehicle: Avoid sharp turns or abrupt ma-
neuvers, if at all possible. As with
other vehicles of this type, failure
to operate this vehicle correctly
may result in loss of control or ve-
hicle rollover.
Avoid loading any items on the
roof that will make the center of
gravity even higher.
Always slow down in gusty cross-
winds. Because of its high center
of gravity, your vehicle is more
sensitive to side winds than an or-
dinary passenger car. Slowing
down will allow you to have much
better control.
Do not drive horizontally across steep slopes. Driving straight up
or straight down is preferred. Your
vehicle (or any similar off-road
vehicle) can tip over sideways
much more easily than forward or backward.

128
When driving off-road or in
rugged terrain, do not drive at ex- cessive speeds, jump the vehicle,
or strike objects, etc. This may cause loss of control or vehicle
rollover. You are also risking ex-
pensive damage to your vehicle's suspension and chassis. Drive gently and avoid high speeds.
Your vehicle does not need an elaborate break-in. But following a few simple tips
for the first 1600 km (1000 miles) can add
to the future economy and long life of your vehicle:
Do not drive over 88 km/h (55 mph).
Run the engine at moderate speed be- tween 2000 and 4000 rpm.
Avoid full-throttle starts.
Try to avoid hard stops during the first
300 km (200 miles).
Do not drive slowly with the manual
transmission in a high gear.
Do not drive for a long time at any
single speed, either fast or slow.
Do not tow a trailer during the first 800
km (500 miles) FUEL TYPE
Your new vehicle must use only un-
leaded gasoline.
To help
prevent gas station mix-ups, your
Toyota has a new smaller fuel tank open- ing. The special nozzle on pumps with un-
leaded fuel will fit it, but the larger stan-
dard nozzle on pumps with leaded gas will
not.
NOTICE
Do not use leaded gasoline. Use of leaded gasoline will cause the
three-way catalytic converter to lose its effectiveness and the emis-sion control system to function im- properly. Also, this can increasemaintenance costs.
OCTANE NUMBER
Select Research Octane Number 91
(Octane Rating 87) or higher.
Use of unleaded fuel with an octane num- ber or rating lower than stated above will
cause persistent heavy knocking. If se-
vere, this will lead to engine damage.
Break-in period Fuel

129
If your engine knocks...
If you detect heavy knocking even when
using the recommended fuel, or if you
hear steady knocking while holding a
steady sp
eed on level roads, consult your
Toyota dealer.
However, now and then, you may notice
light knocking for a short time while accel-
erating or driving up hills. This is no cause
for concern.
GASOLINES CONTAINING DETER-
GENT ADDITIVES
Toyota recommends use of gasolines
that contain detergent additives to
avoid build-up of engine deposits.
For further details, ask your Toyota dealer
or a local gasoline retailer.
GASOLINES CONTAINING MTBE
Gasolines that contain MTBE (Methyl
Tertiary-Butyl Ether) are available in
the market. If you use a gasoline mixed
with MTBE, make certain that it does
not contain more than 15% of MTBE.
If the use of gasolines containing MTBE causes poor driveability and/or poor fuel
economy, you should discontinue the use
of fuels containing MTBE. GASOLINES CONTAINING ALCOHOL
If you use gasohol in your Toyota, be sure that it is unleaded, has an octane
rating no lower than 87 and does not
contain more than 10% ethanol.
Gasohol is a
mixture of gasoline and etha-
nol.
Toyota does not recommend the use of
gasolines containing m ethanol. If you use
gasoline containing methanol, use only
gasoline meeting the requirements above
and also containing less than 5% metha-
nol with cosolvents and corrosion inhibi-
tors for methanol.
NOTICE
Do not use gasohol other than
stated above. It will cause fuel
system damage or vehicle per-formance problems.
If driveability problems are en-
countered (poor hot starting, va- porizing, engine knock, etc.),discontinue the use.
Take care not to spill gasohol
during refueling. Gasohol maycause paint damage.
FUEL TANK CAPACITY
70 L (18.5 gal., 15.4 Imp. gal.)

130
If you plan to drive your Toyota in
another country... First,
comply with the vehicle registration
laws. Second, confirm the availability of the
correct fuel (unleaded and minimum oc- tane number).
The three-way catalytic converter is
an emission control device installed in
the exhaust system.
The purpose is to reduce pollutants in the exhaust gas.
CAUTION!
Keep people and combustible ma- terials away from the exhaust pipe
while the engine is running. The
exhaust gas is very hot.
Do not drive, idle or park your ve-
hicle over anything that might burn
easily such as grass, leaves, paper
or rags.
NOTICE
A large amount of unburned gases flowing into the three-way catalytic
converter may cause it to overheat and create a fire hazard. To preventthis and other damage, observe the following precautions:
Use only unleaded gasoline.
Do not drive with an extremelylow fuel level; running out of fuelcould cause the engine to misfire,
creating an excessive load on the
three-way catalytic converter.
Do not allow the engine to run at idle speed for more than 20 min- utes.
Avoid racing the engine.
Do not push-start or pull-start
your vehicle.
Do not turn off the ignition whilethe vehicle is moving.
