2. In front of the vehicle, pull up on theauxiliary catch lever and lift the hood.3. Hold the hood open by insertingthe support rod into the slot.
Before closing the hood, check that you
have not forgotten any tools, rags, etc.
and return the support rod to its clip-this
prevents ra ttles. Then lower the hood until
it is about 20 cm (8 in.) above the engine
compartment and release it. If the hood is
still not fully closed, lift and release the
hood again. After closing the hood, make sure it is securely locked.
If you notice while driving that the hood is not securely locked, stop the vehicle at
once and close the hood.
Right after driving the support rod may be hot, so only touch the part coated with nylon.
After inserting the rod into the slot,
make sure the rod supports the
hood securely from falling down on
to your head or body.
When closing the hood, be careful
not to get your hands caught be-
tween the hood and the vehicle
body.
NOTICE
Do not press on the hood, or you may deform the hood.

(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, slowdown and pull off the
road. Then stop the vehicle carefully.There maybe 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 yournearest 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.)
It is dangerous to continue driving
normally when the brake fluid level
is low. CAUTION
!
If the brake fluid level is correct...
Have the warning system checked by
your Toyota dealer. (b) Seat Belt Reminder Light and Buzzer
Once the ignition key is turned to ONº or
STARTº, the reminder light and buzzer
come on if the driver's seat belt is not fas-
tened. Unless the driver fastens the belt,
the light stays on and the buzzer stops af-
ter 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, ra dio, ect., and drive directly to the
nearest Toyota dealer or repair shop.

73
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.
Do not drive the vehicle with the
warning light onÐeven for one
block. It may ruin the engine. CAUTION
! (e) 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.
(f) 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.
(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), 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.
(h) Open Door Warning Light
This light remains on until all the doors
and back door are completely closed.
(i) Automatic Transmission Fluid Tem-
perature Warning Light (four-
wheel drive models)
This light warns that the automatic trans- mission fluid temperature is too high.

74If this light comes on while you are driving,
slow
down and pull off the road. Stop the
vehicle at a safe place and put the selector
lever in pº. With the engine idling, wait
until the light goes off If the light goes off,
you can start the vehicle again. If the light
does not go off, call a Toyota dealer or
qualified repair shop for assistance.
NOTICE
Continued driving with the warning light on may damage the automatic
transmission.
(j) SRS Airbag Warning Light This light will come on when the igni-
tion key is turned to the ACCº or ONº
position. After about 6 seconds, the
light w ill go off. This means the airbag
system is operating properly.
The warning light system monitors the
front airbag sensors, center airbag sensor
assembly, inflators, warning light, inter-
connecting wiring 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 ACCº or
ONº position or remains on.
The light comes on while driving.
(k) Light Reminder Buzzer
This buzzer will sound if the driver's door is opened with the key removed from the
ignition switch and the headlight switch
left on. (l) Key Reminder Buzzer
This buzzer reminds you to remove the
key when you open the driver's door with the ignition key in the ACCº or LOCKº position.
CHECKING SERVICE REMINDER INDI-
CATORS (except the low fuel level
warning light)
1. Apply the parking brake.
2. Open one of the doors. The open door warning light should come on.
3. Close the door. The open door warning light should go
off.
4. Turn the ignition key to ACCº. The SRS airbag warning light should
come on. It goes off after about 6 sec-onds. 5. Turn the ignition key to ONº, but do
not start the engine.
All the service reminder indicators ex-
cept the open door warning light, SRS
airbag warning light and automatictransmission fluid temperature warn-
ing light should come on. The ABSº
warning light goes off after about 3 seconds.
6. Turn the ignition key to STARTº. The automatic transmission fluid tempera-
ture warning light should come on.
If any service reminder indicator or warn-
ing buzzer does not function as described above, either the bulb is burned out or the
circuit is in need of repair. Have it checked
by your Toyota dealer as soon as pos-sible.

NOTICE
Do not hold the vehicle on an upgrade with the accelerator pedal.
It can cause the transmission tooverheat. Always use the brake pedal or parking brake.
(g) Rocking your vehicle if stuck
To rock you vehicle if it becomes
stuck in snow, mud, sand, etc., first check that there are no objects or
people around the vehicle. During
the rocking operation the vehicle
may suddenly move forward or
backward as it becomes unstuck,
causing injury or damage to nearby
people or objects. CAUTION
!
NOTICE
If you rock your vehicle, observe the following precautions to prevent
damage to the transmission andother parts.
Do not depress the acceleratorpedal while shifting the selectorlever or before the transmission is
completely shifted to forward or reverse gear.
Do not race the engine and avoid
spinning the wheels.
If your vehicle remains stuck afterrocking the vehicle several times,
consider other ways such as tow-ing.
(h) Driving in POWERº mode In the POWERº mode, the transmission
is shifted up and down at a higher vehicle
speed than in the NORMALº mode and a
more powerful acceleration is achieved.
To set the POWERº mode, push in the
driving pattern selector button. The
POWERº mode indicator light comes on.
For ordinary driving, Toyota recommends
using the NORMALº mode to improve
fuel economy.
(i) If you cannot shift the selector lever
out of Pº position
If you cannot shift the selector lever from the Pº position even though the brake
pedal is depressed, use the shift lock
override button. For instructions, see If you cannot shift automatic transmission selector leverº in Part 4.

81

When towing a trailer, in order to main-
tain engine braking efficiency, do not
use the fifth gear.
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to spin orskid. CAUTION
!
NOTICE
Make sure the vehicle is completely stopped before shifting into
reverse.
The center differential lock system is pro-
vided for use only when the vehicle does not have enough traction to move itself out of the following situations. All front wheels or rear wheels are off the ground or on a slippery surface.
One of the four wheels is off the ground or on a slippery surface.
Operating precautions If the front wheels and rear wheels are
worn unevenly, the center differential
may not lock or unlock smoothly.
Before locking the center differential,
make sure the wheels have stopped spinning.
Unlock the center differential immedi-
ately after you finish using the center
differential lock system. An indicatorbuzzer will sound while the center dif-ferential is being unlocked.
After you have pushed the center dif-ferential lock switch to lock and moved
the vehicle a short distance, the indi-
cator light in the instrument panel
stays on. If the light either fails to come
on or goes out, ask your Toyota dealer
to check the electrical system and the
locking mechanism.
The center differential must be un- locked in normal driving. Locking the center differential will result in
difficult cornering control. CAUTION
!
NOTICE
Do not drive on a dry paved surface with the center differential locked.
This may damage the lockingmechanism and the drive system.

If the preset speed automatically cancels
out other than for the above cases or, if the
indicator light flashes several times, the
cruise control may be malfunctioning. In such
cases, have your vehicle checked by
your Toyota dealer at the earliest opportu-
nity.
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.
On vehicles with automatic transmission,
even if you turn off the overdrive switchwith 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.

Keep
your engine in good running
order. Malfunctions in the engine
electrical system, electronic igni-tion system/distributor ignitionsystem or fuel systems could
cause an extremely high three-
way catalytic converter tempera-ture.
If the engine becomes difficult to
start or stalls frequently, take your
vehicle in for a check-up as soon
as possible. Remember, your To-
yota dealer knows your vehicleand its three-way catalytic con-
verter system best.
To ensure that the three-way cata-lytic converter and the engine
emission control system operate
properly, your vehicle must re-ceive the periodic inspections re-
quired by the Toyota Maintenance
Schedule. For scheduled mainte- nance information, refer to the
separate Owner's Manual Sup- plement/Maintenance Scheduleº.
CAUTION!
Avoid inhaling the engine ex-
haust. It contains carbon monox-
ide, which is a colorless and odor-
less gas. It can cause uncon-
sciousness or even death.
Make sure the exhaust system
has no holes or loose connec-
tions. 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 paticularly
dangerous situation.
Do not remain for a long time in a
parked vehicle with the engine
running. If it is unavoidable, how-
ever, do so only in an unconfined
area and adjust the heating or
cooling system to force outside air into the vehicle.Keep the back door closed while
driving. An open or unsealed back door may cause exhaust gases to be drawn into the ve-
hicle. If you must drive with theback door open to accommodate a large object, close the windows,
open all the instrument panel vents and have the heating or
cooling system deliver fresh air
into the vehicle by turning the fan
to high speed with the air intake
control lever set at the outside air position.
To allow proper operation of your
vehicle's ventilation system, keep
the inlet grilles in front of the
windshield clear of snow, leaves, or other obstructions.
If you smell exhaust fumes in the
vehicle, drive with the windows
open and the back door closed.
Have the cause immediately lo- cated and corrected.

11 2FUNCTIONS OF ENGINE OIL
Engine oil has the primary functions of lu-
bricating and cooling the inside of the en-
gine,
and plays a major role in maintaining
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 piston
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 com-
bustion gases during the combustionprocess.
Oil is also used to lubricate the stems
of the intake valves. Some of this oil is
sucked into the combustion chamber
together with the intake air and is
burned along with the fuel. High tem-perature exhaust gases also burn the
oil used to lubricate the exhaust valve stems.
The amount of engine oil consumed
depends on the viscosity of the oil, the
quality of the oil and the conditions
the vehicle is driven under. More oil is consumed by high-speed driv-
ing and frequent acceleration and decel- eration.
A new engine consumes more oil, since
its pistons, piston rings and cylinder walls
have not become conditioned.
When judging the amount of oil con-
sumption, note that the oil may be-come diluted and make it difficult to
judge the true level accurately.
As an example, if a vehicle is used for re-
peated short trips, and consumes a nor- mal amount of oil, the dipstick may not
show any drop in the oil level at all, even after 1000 km (600 miles) or more. This is because the oil is gradually becoming
diluted
with fuel or moisture, making it ap-
pear that the oil level has not changed.
The diluting ingredients evaporate out
when the vehicle is then driven at high
speeds, as on an expressway, making itappear that oil is excessively consumed
after driving as high speeds.
IMPORTANCE OF ENGINE OIL LEVEL CHECK
One of the most important points in proper vehicle maintenance is to keep the engine
oil at the optimum level so that oil function
will not be impaired. Therefore, it is essen-
tial that the oil level be checked regularly.
Toyota recommends that the oil level bechecked every time you refuel the vehicle.
Failure to check the oil level regular-
ly could lead to serious engine
trouble due to insufficient oil.
NOTICE
For detailed information on the oil level
check, see Checking the engine oil levelº
in Chapter 7-2.

TANDEM MASTER CYLINDER BRAKE SYSTEM
The tandem master cylinder brake sys-
tem is a hydraulic system with two sepa-
rate sub-systems. If either sub-system
should fa
il, the other will still work. Howev-
er, the pedal will be harder to press, and
your stopping distance will be longer.
Also, the brake system warning light may come on.
CAUTION!
Do not drive your vehicle with only a single brake system. Have your
brakes fixed immediately.
BRAKE BOOSTER
The brake booster uses engine vacuum to
power-assist the brakes. If the engine
should quit while you are driving, you can
bring the vehicle to a stop with normal
pedal pressure. There is enough reserve vacuum for one or two stopsÐbut nomore!
CAUTION!
Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your vacuum re- serve.
Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push
the pedal hardÐmuch harder
than normal. And your braking
distance will be longer.
ANTI-LOCK BRAKE SYSTEM (with ABSº warning light)
The anti-lock brake system is designed to
automatically help prevent lock-up of the
wheels during sudden braking or braking on slippery road surfaces. This assists in
providing directional stability and steeringperformance of the vehicle under these circumstances.
The anti-lock brake system becomes op- erative after the vehicle has accelerated
to a speed in excess of approximately 10
km/h (6 mph). It stops operating when the
vehicle decelerates to a speed below
approximately 5 km/h (3 mph). You may hear a sound in the engine
compartment for a
few seconds when the
engine is started or just after the vehicle is started. This means that the anti-lock
brake system is in the self check mode,
and does not indicate a malfunction.
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.
