The gauge works when the ignition
switch is on and indicates the approxi-
mate quantity of fuel remaining in the
tank.
It is a good idea to keep the tank over
1/4 full.
The needle moves when braking, acceler-
ating or making turns. This is caused by
the fuel moving in the tank.
If the fuel level approaches ”E” or the low
fuel level warning light comes on, fill the
fuel tank as soon as possible.
If the fuel tank is completely empty, the
malfunction indicator lamp comes on. Fill
the fuel tank immediately. The indicator lamp goes off after driving
several times. If the indicator lamp does
not go off, contact your Toyota dealer as
soon as possible.
On inclines or curves, due to the move-
ment of fuel in the tank, the fuel gauge
needle may fluctuate.

NOTICE
Do not remove the thermostat in
the engine cooling system as this
may cause the engine to overheat.
The thermostat is designed to con-
trol the flow of coolant to keep the
temperature of the engine within
the specified operating range.
Do not continue driving with an
overheated engine. See ”If your ve-
hicle overheats” in Part 4.
Oil pressure gauge
The oil pressure gauge indicates engine
oil pressure when the ignition is on.
Check it while driving to make sure
that the needle is in the proper range.
If the oil pressure should stay below the
normal range, pull off the road to a safe
place and stop the engine immediately.
Call a Toyota dealer or qualified repair
shop for assistance.
Oil pressure may not build up when the
oil level is too low. The oil pressure
gauge is not designed to indicate oil level,
and the oil level must be checked using
the level dipstick.
NOTICE
Do not drive the vehicle with the oil
pressure below the normal range until
the cause is fixed–it may ruin the en-
gine.

(a) Brake System Warning Light
This light has the following functions:
Parking brake reminder
If this light is on, make sure the parking
brake is fully released. The light should
go off.
Low brake fluid level warning
If this light comes on and stays on while
you are driving, slow down and pull off
the road. Then stop the vehicle carefully.
Remember that stopping distance pedal
effort may be increased. There may be a
problem somewhere in the brake system.
Check the fluid level of the see-through
reservoir.
To make sure the parking brake has not
caused the warning light to come on,
check to see that the parking brake is
fully released.
If the brake fluid level is low...
At a safe place, test your brakes by start-
ing and stopping.
If you judge that the brakes still work
adequately, drive cautiously to your
nearest dealer or shop for repairs.
If the brakes are not working, have the
vehicle towed in for repairs. (For tow-
ing information, see Part 4.)
CAUTION
It is dangerous to continue driving
normally when the brake fluid level is
low.
If the brake fluid level is correct...
Have the warning system checked by your
Toyota dealer.
(b) Seat Belt Reminder Light and Buzz-
er
Once the ignition key is turned to ”ON” or
”START”, the reminder light and buzzer
come on if the driver’s seat belt is not
fastened. Unless the driver fastens the
belt, the light stays on and the buzzer
stops after about 4 to 8 seconds.
(c) Discharge Warning Light
This light warns that the battery is being
discharged.
If it comes on while you are driving, there
is a problem somewhere in the charging
system. The engine ignition will continue to oper-
ate, however, until the battery is dis-
charged. Turn off the air conditioning,
blower, radio, etc., 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
driving, pull off the road to a safe place
and stop the engine immediately. Call a
Toyota dealer or qualified repair shop for
assistance.
The light may occasionally flicker when
the engine is idling or it may come on
briefly after a hard stop. There is no
cause for concern if it then goes out when
the engine is accelerated slightly.
The light may come on when the oil level
is extremely low. It is not designed to
indicate low oil level, and the oil level
must be checked using the level dipstick.

YOUR RADIO ANTENNA
To lower a manual antenna, carefully push
it down.
YOUR CASSETTE PLAYER
When you insert a cassette, the exposed
tape should be to the right.
NOTICE
Do not oil any part of the player and
do not insert anything other than cas-
sette tapes into the slot, or the tape
player may be damaged.
YOUR COMPACT DISC PLAYER
When you insert a disc, gently push it in
with the label side up. (The player will
automatically eject a disc if the label side
is down.) The compact disc player will
play from track 1 through the end of the
disc. Then it will play from track 1 again.
NOTICE
Never try to disassemble or oil any
part of the compact disc player. Do
not insert anything except a compact
disc into the slot.
8 cm (3 in.) compact disc singles
Your compact disc player does not need
an adaptor to play compact disc singles.
Compact disc singles are about 8 cm (3
in.) in diameter
−smaller than standard
discs.
After you eject a compact disc single, do
not insert a standard 12 cm (5 in.) disc
until ”DISC” disappears from the display.
NOTICE
Do not use an adaptor for compact
disc singles it could cause tracking
errors or interfere with the ejection of
compact discs.

Types of tires
This vehicle is one of the class of ve-
hicles which have higher ground clear-
ance and narrower tread in relation to
the height of their center of gravity to
make them capable of performing in a
wide variety of off-road applications.
Specific design characteristics give it a
higher center of gravity than ordinary
cars. An advantage of the higher
ground clearance is a better view of the
road allowing you to anticipate prob-
lems. It is not designed for cornering
at the same speeds as conventional
two-wheel drive vehicles any more than
low-slung sports cars are designed to
perform satisfactorily under off-road
conditions.
CAUTION
Always observe the following precau-
tions to minimize the risk of serious
personal injury or damage to your ve-
hicle: Avoid sharp turns or abrupt maneu-
vers, if at all possible. As with oth-
er vehicles of this type, failure to
operate this vehicle correctly may
result in loss of control or vehicle
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 sensi-
tive to side winds than an ordinary
passenger car. Slowing down will
allow you to have much better con-
trol.
Do not drive horizontally across
steep slopes. Driving straight up or
straight down is preferred. Your ve-
hicle (or any similar off-road ve-
hicle) can tip over sideways much
more easily than forward or back-
ward.

Engine exhaust cautions
CAUTION

Avoid inhaling the engine exhaust.
It contains carbon monoxide, which
is a colorless and odorless gas. It
can cause unconsciousness or even
death.
Make sure the exhaust system has
no holes or loose connections. The
system should be checked from
time to time. If you hit something,
or notice a change in the sound of
the exhaust, have the system
checked immediately.
Do not run the engine in a garage
or enclosed area except for the
time needed to drive the vehicle in
or out. The exhaust gases cannot
escape, making this a particularly
dangerous situation.
Do not remain for a long time in a
parked vehicle with the engine run-
ning. If it is unavoidable, however,
do so only in an unconfined area
and adjust the heating or cooling
system to force outside air into the
vehicle.
To allow proper operation of your
vehicle’s ventilation system, keep
the inlet grilles in front of the wind-
shield clear of snow, leaves, or oth-
er obstructions.
If you smell exhaust fumes in the
vehicle, drive with the windows
open. Have the cause immediately
located and corrected.
Toyota does not recommend occu-
pying the rear cargo area when it
is fitted with a slide-in camper,
camper shell or other type cover
while the engine is running. This
caution applies to both driving and
stopped or parked situations with
the engine running. Particular care
should be taken to prevent exhaust
gases from entering camper bodies,
trailers or other enclosures on or
around your vehicle. If exhaust
fumes are detected, open all win-
dows and thoroughly ventilate the
area.FUNCTIONS OF ENGINE OIL
Engine oil has the primary functions of
lubricating and cooling the inside of the
engine, and plays a major role in main-
taining the engine in proper working order.
ENGINE OIL CONSUMPTION
It is normal that an engine should con-
sume some engine oil during normal
engine operation. The causes of oil
consumption in a normal engine are as
follows.
Oil is used to lubricate pistons, piston
rings and cylinders. A thin film of oil
is left on the cylinder wall when a pis-
ton moves downwards in the cylinder.
High negative pressure generated when
the vehicle is decelerating sucks some
of this oil into the combustion chamber.
This oil as well as some part of the oil
film left on the cylinder wall is burned
by the high temperature combustion
gases during the combustion process.
