The automatic air conditioning is an air
conditioning that automatically maintains the set temperature.
This air conditioning features automatic
air intake controls, fan speed and air flow controls which automatically select the
most suitable air intake control, fan speed
and air flow to control the temperature.
You may use manual controls if you desire your own way of setting.
(A) CLIMATE CONTROL Setting operation
1. Turn the temperature control knob at the desired temperature level.
The temperature control knob is used to
set the desired passenger compartment
temperature. The tem
perature of air deliv-
ered to the passenger compartment will
be controlled automatically according to
the setting. The figures on the panel indi-
cate degrees in centigrade or Fahrenheit. 2. Press in the AUTOº button.
As the AUTOº button is pressed in, the fan turns on and operates with the most
suitable air intake control, air flow (except
pressing the FLOOR/WINDSHIELD or
WINDSHIELD button) and fan speed se-lected
automatically according to the tem-
perature. In cold weather, however, the
fan will not operate until the engine cool-
ant warms up sufficiently.
3. If any of the AUTOº button functions is not necessary for your own way of set-
ting, manual control can be made on each
of the functions, leaving the rest of the
functions in operation. Operate the con-
trols as described in Manual control on air
intake, air flow and fan speedº after the
AUTOº button is pressed in.
4. Press in the air conditioning on-off but-
ton.
The air conditioning on-off button is used
to turn on and off the air conditioning.
With the button pressed in the on mode, the air conditioning turns on.
If the system is used for ventilation or
heating in dry weather, press the air con-
ditioning on-off button once again. This
turns off the air conditioning. For year-
round automatic temperature control in-
cluding cooling and dehumidifying opera-
tion, use the air conditioning. 5. Press in the OFFº button turn off thefan speed and temperature control.
Manual control on air intake, air flow
and fan speed

The digital clock indicates the time
with the ignition key at the ACCº or
ONº position. To reset the hour, de-
press the
Hº button. To reset the min-
utes, depress the Mº button. To ad-
just the time to a full hour, depress the
:00º button.
For example, if the :00º button is de-
pressed when the time is between
1:01Ð1:29, the time will change to 1:00.
If the time is between 1:30Ð1:59, the time
will change to 2:00. When the instrument panel lights are turned on, the brightness of the time indi- cation will be reduced.
Once the electrical power source has
been disconnected from the clock, the
time is automatically set to 1:00 (oneo'clock).To operate the cigarette lighter, press
it in. When it becomes heated, it auto-
matically pops out ready for use.
If the engine is not running, the key must be in the ACCº position.
Do not hold the cigarette lighter pressed in. When finished with your cigarette, thor-
oughly extinguish it in the ashtray to pre-
vent other cigarette butts from catching
fire. After using the ashtray, close the ash-
tray cover completely.
To remove the ashtray, open the ashtray cover and pull it out.
Use a Toyota genuine cigarette lighter or equivalent for replacement.

105
Leave the system on during ordinary
driving so that it can operate when
needed. When traction control is ap-
plied, the slip indicator light blinks. If
your vehicle still skids even though
traction control is applied, more pow-
erful
traction control is applied and the
SNOWº indicator light comes on.
You may hear a slight clicking noise in the
engine compartment when the engine is
started. This means that the traction con-
trol system is in the self-check mode, and
does not indicate malfunction. When the
traction control system is operating, you
may feel vibration of your vehicle, causedby operation of the brakes. This indicates
the system is functioning properly.
When getting the vehicle out of mud or
new snow, etc. the traction control system
will operate to prevent the wheels from
spinning. Even though the accelerator
pedal is fully depressed, the engine speed
will be restrained to a certain level.
MANUAL SNOW OPERATION
You can select the snow mode by
pushing the SNOWº switch. The
SNOWº indicator light will come on.
To select the automatic mode, push
the OFFº switch. The SNOWº indi-cator light will go off. If your vehicle
still skids, the system automatically operates.
MANUAL TRACTION CONTROL OFF
OPERATION
You can turn off the traction control
system by pushing the OFFº switch.
The TRAC OFFº indicator/warning
light will come on. Pushing the OFFº
switch a second time turns on the trac-
tion control system and the TRAC
OFFº indicator/warning light will go off. If the SNOWº indicator light is on,
pushing the OFFº switch once se-lects the automatic mode and pushing
it a second time turns off the traction
control system.

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).
Do not run the engine over 4000 rpm. Maintain engine speed between 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. FUEL TYPE
Your new vehicle must use only un-
leaded gasoline.
To help prevent gas station mixups, 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 tolose its effectiveness and the emission control system tofunction improperly. Also, this can increase maintenance costs.
OCTANE NUMBER
Select premium unleaded gasoline
with a Research Octane Number of 96
(Octane Rating 91) or higher for opti-
mum engine performance. However, if
such premium type cannot be ob-
tained, you may temporarily use un-
leaded gasoline with an octane num-ber as low as 91 (Octane Rating 87).
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.

108If 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 I
f 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 methanol. 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 perfor-
mance problems.
If driveability problems are en-countered (poor hot starting, va-porizing, engine knock, etc.),discontinue the use.
Take care not to spill gasohol dur-
ing refueling. Gasohol may causepaint damage.
FUEL TANK CAPACITY 70 L (18.5 gal., 15.4 Imp. gal.) 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). Operation in foreign countries

109
The three-way catalytic converter is
an emission control device installed in
the exhaust system.
Its 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.
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 extremely low fuel level; running out of fuel
could cause the engine to mis-fire, creating an excessive load
on the three-way catalytic con-verter.
Do not allow the engine to run atidle speed for more than 20 min-
utes.
NOTICE
Avoid racing the engine.
Do not push-start or pull-start
your vehicle.
Do not turn off the ignition whilethe vehicle is moving.
Keep your engine in good run-
ning order. Malfunctions in theengine electrical system, elec-
tronic ignition system/distributorignition system or fuel systemcould cause an extremely high
three-way catalytic converter
temperature.
If the engine becomes difficult to start or stalls frequently, takeyour vehicle in for a check-up assoon as possible. Remember,
your Toyota dealer knows your
vehicle and its three-way catalyt-ic converter system best.
To ensure that the three-way cat-
alytic converter and the entireemission 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 theseparate Owner's Manual Sup-
plement/Maintenance Scheduleº.

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 es-
cape, 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.
Keep the back door closed while
driving. An open or unsealed back
door may cause exhaust gases to
be drawn into the vehicle. If you
must drive with the back door
open to accommodate a large ob-
ject, close the windows, open all
the instrument panel vents and have the heating or cooling sys- tem deliver fresh air into the ve-
hicle by turning the fan to high
speed with the air intake control
button in the OUTSIDE AIR mode.
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
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. FUNCTIONS 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.
Engine exhaust cautions
Facts about engine oil consumption

111
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 di-
luted 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 it appear that oil is excessively consumed
after driving at 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 be checked every time you refuel the vehicle.
NOTICE
Failure to check the oil level regularly could lead to serious
engine trouble due to insufficientoil.
For detailed information on 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 fail, the other w
ill 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.
Do not drive your vehicle with only
a single brake system. Have your
brakes fixed immediately.
CAUTION!
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 reservevacuum for one or two stopsÐbut no more!
Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your vacuum re- serve.
CAUTION!
Brake system

11 2
Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hardÐmuch harder t han nor-
mal. And your braking distance will
be longer.
ANTI-LOCK BRAKE SYSTEM
The anti-lock brake system is designed to prevent lock-up of the wheels during sud-
den braking or braking on slippery road surfaces. This assists the driver in con-
trolling the vehicle under these circum-stances.
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.
When the anti-lock brake system function is in action, you may feel the brake pedal
pulsating and hear a noise. In this situa-
tion, to let the anti-lock brake system work for you, just hold the brake pedal
down more firmly. Do not pump the brake. 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 c apability 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 differences in surface height.
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 either of the following conditions occurs, this indicates a malfunction somewhere inthe 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.

11 4
Do not drive with objects left on
top of the instrument panel. They
may interfere with the driver's field
of view. Or they may move during
sharp vehicle acceleration or turn-
ing, and impair the driver's control
of the vehicle. In an accident they
may injure the vehicle occupants.
NOTICE
Do not load the vehicle beyond
the vehicle capacity weight speci-
fied in Part 8.
If using a roof luggage carrier onsport roofs, avoid prolonged driv-
ing on rough roads with heavy items on the roof luggage carrier.
Some Toyotas are equipped with a limit-
ed-slip differential. If one rear wheel be-
gins to spin, the limited-slip differential is
designed to aid traction by automatically
transmitting driving force to the other rear
wheel. If you are not sure whether your
vehicle is equipped with one, you can ask
your Toyota dealer.
CAUTION!
Do not start or run the engine while your vehicle is supported by a jack.
The vehicle could be driven off the
jack and could pose a danger or re-
sult in serious injury.
Use only a spare tire of the same size, construction and load capacity
as the original tires on your Toyotabecause damage to the limited-slip differential could possibly occurwith another tire type.
NOTICE
The vehicle identification number (VIN)
is the legal identifier for your vehicle.
This number is on the left top of the in-
strument panel, and can be seen
through the windshield from outside.
The vehicle identification number (VIN) is
also on the Certification Label.
This is the primary identification number
for your T oyota. It is used in registering the
ownership of your vehicle.
