NOTICE
Be careful not to overrev the engine when using 2º or Lº position.
If the automatic transmission fluid tem-
perature becomes too high, the MANUº mode indicator light flashes for several
seconds and goes off. The driving mode then automatically changes from manual mode to the normal driving mode.
To cancel the manual mode, push the
MANUº button once again. The MANUº
mode indicator light will go off and thetransmission system will work in the nor- mal driving mode.
The manual mode automatically cancels
out when the ignition switch is off.
(h) 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.
The shift pattern is conventional as
shown above.
Press the clutch pedal down fully while
shifting, and then release it slowly. Do not
rest your foot on the pedal while driving, because it will cause clutch trouble. And do not use the clutch to hold the vehicle
when stopped on an uphill gradeÐuse the
parking brake. Recommended shifting speeds
The transmission is fully synchronized
and upshifting or downshifting is easy.
For the best compromise between fuel
economy and vehicle performance, you
should upshift or downshift at the follow-
ing speeds:
gear km/h (mph)
1 to 2 or 2 to 1 24 (15)
2 to 3 or 3 to 2 40 (25)
3 to 4 or 4 to 3 64 (40)
4 to 5 or 5 to 4 72 (45)
Upshifting too soon or downshifting too late
will cause lugging, and possibly pinging.
Regularly revving the engine to maximum
speed in each gear will cause excessive
engine wear and high fuel consumption. Maximum allowable speeds
To get on a highway or to pass slower traf- fic, maximum acceleration may be neces-
sary. Make sure you observe the following
maximum allowable speeds in each gear:
gear km/h (mph) 1 54 (34)
2 94 (59)
3 139 (87)

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 3
Even if the anti-lock brake system
should
fail, the brake system will still operate con-
ventionally. Have your vehicle checked by
your Toyota dealer as soon as possible.
DRUM-IN-DISC TYPE PARKING BRAKE SYSTEM
Your vehicle has a drum-in-disc type
parking brake system. This type of brake
system needs bedding-down of the brake
shoes periodically or whenever the park-
ing brake shoes and/or drums are re- placed.
Have your Toyota dealer perform the bed-
ding-down.
The brake pad wear limit indicators on
your disc brakes give a warning noise
when 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. When stowing luggage or cargo in or on the vehicle, observe the following:
Put luggage or cargo in the luggage
compartment when at all possible. Be sure all items are secured in place.
Be careful to keep the vehicle bal-
anced. Locating the weight as far for-
ward as possible helps maintain this.
For better fuel economy, do not carry unneeded weight.
CAUTION!
To prevent luggage or packages
from sliding forward during brak-
ing, do not stack anything in the
luggage compartment higher than
the seatbacks. Keep luggage or
packages low, as close to the floor
as possible.
Never allow anyone to ride in the lug-
gage compartment. It is not de-
signed for passengers. They s hould
ride in their seats with their seat belts
properly fastened. Otherwise, they
are much more likely to suffer seri-
ous bodily injury, in the event of sud-
den braking or a collision.
Do not place anything on the lug-
gage cover. Such items may be
thrown about and possibly injure people in the vehicle during sud-
den braking or an accident.

Manual transmission: Press the
clutch pedal to the floor and shift the trans-
mission into neutral. Hold the clutch pedal
to the floor until the engine is started. A
starter safety device will prevent the start-
er from operating if the clutch pedal is not fully depressed.
Automatic transmission: Put the selec-
tor lever in Pº. If you need to restart the
engine while the vehicle is moving, put the
selector lever in Nº. A starter safety de-vice will prevent the starter from operating
if the selector lever is in any drive position. 4. Automatic transmission only: De-
press the brake pedal and hold it to the
floor until driving off.

11 8Before starting the engine, be sure to fol-
low the instructions in (a) Before crank- ingº.
Normal starting procedure
The multiport fuel injection system/se-
quential multiport fuel injection system in
your engine automatically controls the
proper air-fuel mixture for starting. You can start a cold or hot engine as follows:
1. With your foot off the accelerator ped- al, crank the engine by turning the key to
STARTº. Release it when the enginestarts.
2. After
the engine runs for about 10 sec-
onds, you are ready to drive.
If the weather is below freezing, let the en-
gine warm up for a few minutes before driving.
If the engine stalls...
Simply restart it, using the correct proce- dure given in normal starting. If the engine will not startÐ
See If your vehicle will not startº in Part 4.

Do not crank for more than 15 sec-onds at a time. This may overheat
the starter and wiring systems.
Do not race a cold engine.
NOTICE
If the engine becomes difficult tostart or stalls frequently, have the
engine checked immediately.After high-speed or extended driving,
etc., requiring a heavy engine load, the
engine should be allowed to idle, as
shown in the chart, before turning it off.

Always slow down in gusty cross- winds. This will allow you much better control.
Drive slowly onto curbs and, if pos-
sible, at a right angle. Avoid drivingonto high, sharp-edged objects and
other road hazards. Failure to do so
can lead to severe tire damage result-
ing in tire bursts.
When parking on a hill, turn the front
wheels until they touch the curb so that
the vehicle will not roll. Apply the park-
ing brake, and place the transmission in Pº (automatic) or in first or reverse
(manual). If necessary, block thewheels.
Washing your vehicle or driving
through deep water may get the
brakes wet. To see whether they are
wet, check that there is no traffic near
you, and then press the pedal lightly. If
you do not feel a normal braking force,
the brakes are probably wet. To dry
them, drive the vehicle cautiously
while lightly pressing the brake pedal
with the parking brake pulled. If they
still do not work safely, pull to the side
of the road and call a T oyota dealer for
assistance.
CAUTION
Before driving off, make sure the
parking brake is fully released and the parking brake reminder light is off.
Do not leave your vehicle unat- tended while the engine is run-ning.
Do not rest your foot on the brake
pedal while driving. It can cause
dangerous overheating, needless
wear, and poor fuel economy.
To drive down a long or steep hill,reduce your speed and downshift.
Remember, if you ride the brakes
excessively, they may overheat
and not work properly.
Be careful when accelerating, up-
shifting, downshifting or braking
on a slippery surface. Sudden ac-
celeration or engine braking could cause the vehicle to spin or skid.!
Do not drive in excess of the speed
limit. Even if the legal speed limit
permits it, do not drive over 140
km/h (85 mph) unless your vehicle
has high-speed capability tires.
Driving over 140 km/h (85 mph)
may result in tire failure, loss of
control and possible injury. Be sure to consult a tire dealer to de-
termine whether the tires on your
vehicle are high-speed capability tires or not before driving at suchspeeds.
Do not continue normal driving
when the brakes are wet. If they are
wet, your vehicle will require a lon-
ger stopping distance, and it may
pull to one side when the brakes
are applied. Also, the parking
brake will not hold the vehicle se-
curely.
