The gauge indicates the engine cool-
ant temperature when the ignition
switch is on. The engine operating
temperature will vary with changes in
weather and engine load.
If the needle moves into the red zone,
your engine is too hot. If your vehicle
overheats, stop your vehicle and allow the
engine to cool.
Your vehicle may overheat during severe
operating conditions, such as:

Driving up a long hill on a hot day.

Reducing speed or stopping after high
speed driving.

Idling for a long period with the air con-
ditioning on in stop-and-go traffic.

Towing a trailer
NOTICE
Do not remove the thermostat in
the engine cooling system as this
may cause the engine to overheat. The thermostat is designed tocontrol the flow of coolant to keep
the temperature of the engine within the specified operatingrange.
Do not continue driving with an
overheated engine. See If yourvehicle overheatsº in Part 4.The tachometer indicates engine
speed in thousands of rpm (revolu-
tions per minute). Use it while driving
to select correct shift points and to
prevent engine lugging and overrev-
ving.
Driving with the engine running too fast
causes excessive engine wear and poor
fuel economy. Remember, in most cases
the slower the engine speed, the greater
the fuel economy.
NOTICE
Do not let the indicator needle get into the red zone. This may cause
severe engine damage.

Do not continue hill climbing or
hard towing for a long time in the2º or Lº position. This may
cause severe automatic transmis-sion damage from overheating.
To prevent such damage, Dºposition should be used in hill
climbing or hard towing.
(d) Backing up
1. Bring the vehicle to a complete stop.
2. With the brake pedal held down with
your foot, shift the selector lever to the
Rº position.
NOTICE
Never shift into reverse while the vehicle is moving.
(e) Parking
1. Bring the vehicle to a complete stop.
2. Pull the parking brake lever up fully to
securely apply the parking brake.
3. With the brake pedal pressed down,
shift the selector lever to the Pº position.
While the vehicle is moving, never
attempt to move the selector lever
into Pº position under any circu-
mstances. Serious mechanical da-
mage and loss of vehicle control
may result. CAUTION
!
(f) Good driving practice


If the transmission is repeatedly up-
shifted and downshifted between third
gear and overdrive when climbing a
gentle slope, the overdrive switch
should be turned off. Be sure to turn
the switch on immediately afterward.

When towing a trailer, in order to main-
tain engine braking efficiency, do not
use overdrive.
Always keep your foot on the brake
pedal while stopped with the engine
running. This prevents the vehicle
from creeping. CAUTION
!
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
If you rock your vehicle to make it
out when it becomes stuck in snow,
mud, sand, etc., first check that
there is no physical object or people
around the vehicle. During oper-
ation, the vehicle may suddenly
move forward or backward, causing
injury or damage to nearby people
or objects. CAUTION

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).
7A-FE engines
5S-FE engines 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 ex-
haust 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 overheatand create a fire hazard. To prevent
this and other damage, observe thefollowing precautions:
Use only unleaded gasoline.
Do not drive with an extremely low
fuel level; running out of fuelcould cause the engine to misfire,
creating an excessive load on thethree-way catalytic converter.

Before 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 engine
starts.
2. After the engine runs for about 10
seconds, 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 start-
See If your vehicle will not startº in Part 4.NOTICE
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.
If the engine becomes difficult tostart or stalls frequently, have theengine checked immediately.

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 driving
onto 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 the
wheels.

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 that
the parking brake if fully released
and the parking brake reminder
light is off.

Do not leave your vehicle unat-
tended while the engine is running.

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, down shifting 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 con-
sult a tire dealer to determine
whether the tires on your vehicle
are high-speed capability tires or
not before driving at such speeds.

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 securely. Make sure you have ethylene-glycol
antifreeze in the radiator.
Do not use alcohol type antifreeze.
NOTICE
Check the condition of the battery and
cables.
Cold temperatures reduce the capacity of
any battery, so it must be in top shape to
provide enough power for winter starting.
Chapter 7-3 tells you how to visually in-
spect the battery. Your Toyota dealer and
most service stations will be pleased to
check the level of charge.
Make sure the engine oil viscosity is
suitable for the cold weather.
See Chapter 7-2 for recommended vis-
cosity.
Leaving a heavy summer oil in your
vehicle during winter months may cause
harder starting. If you are not sure about
which oil to use, call your Toyota dealer-
he will be pleased to help.
Keep the door locks from freezing.
Squirt lock de-icer or glycerine into the
locks to keep them from freezing. To open
a frozen lock, try heating the key before in-
serting it.

Because of the added load of the trail-
er, your vehicle's engine may overheat
on hot days (at temperatures over
305C [85 5F]) when going up a long or
steep grade with a trailer. If the engine
coolant temperature gauge indicates
overheating, immediately turn off the
air conditioning (if in use), pull off the
road and stop in a safe spot. Refer to
If your vehicle overheatsº in Part 4 of
this manual.

Always place wheel blocks under both
the vehicle and trailer wheels when
parking. Apply the parking brake firm-
ly. Put the transmission in Pº (auto-
matic) or in first or reverse (manual).
Avoid parking on a slope with a trailer,
but if it cannot be avoided, do so only
after performing the following:
1. Apply the brakes and hold.
2. Have someone place wheel blocks un-
der both the vehicle and trailer wheels.
3. When the wheel blocks are in place,
release your brakes slowly until the blocks
absorb the load.
4. Apply the parking brake frimly.
5. Shift into first or reverse (manual) or
Pº (automatic) and turn off the engine.
When restarting out after parking on a
slope: 1. With the transmission in Pº position
(automatic) or the clutch pedal depressed
(manual), start the engine. (With an
auto-
matic transmission, be sure to keep the
brake pedal depressed.)
2. Shift into gear.
3. Release the parking brake (also foot
brake on automatic transmission ve-
hicles) and slowly pull or back away from
the wheels blocks. Stop and apply your
brakes.
4. Have someone retrieve the blocks.

Do not exceed 72 km/h (45 mph) or
the posted towing speed limit,
whichever is lower. Because insta-
bility (swaying) of a towing vehicle
trailer combination usually in-
creases as the speed increases, ex-
ceeding 72 km/h (45 mph) may
cause loss of control.

Slow down and downshift before
descending steep or long downhill
grades. Do not make sudden down-
shifts

Avoid holding the pedal down too
long or too frequently. This could
cause the brakes to overheat and re-
sult in reduced braking efficiency.
CAUTION!
Getting more kilometers/mileage from a li-
ter/gallon of fuel is easy-just take it easy.
It will help make your vehicle last longer,
too. Here are some specific tips on how to
save money on both fuel and repairs:

Keep your tires inflated at the cor-
rect pressure. Underinflation causes
tire wear and wastes fuel. See Chapter
7-2 for instructions.

Do not carry unneeded weight in
your vehicle. Excess weight puts a
heavier load on the engine, causing
greater fuel consumption.

Avoid lenghty warm-up idling.
Once the engine is running smoothly,
begin drivingÐbut gently. Remember,
however, that on cold winter days this
may take a little longer.

Accelerate slowly and smoothly.
Avoid jackrabbit starts. Get into high
gear as quickly as possible.

Avoid long engine idling. If you have
a long wait and you are not in traffic, it
is better to turn off the engine and start
again later.

Avoid engine lug or overrevving.
Use a gear position suitable for the
road on which you are travelling.

Avoid continuous speeding up and
slowing down. Stop-and-go driving
wastes fuel.

Avoid unnecessary stopping and
braking. Maintain a steady pace. Try
to time the traffic signals so you only
need to stop as little as possible or take
advantage of through streets to avoid
traffic lights. Keep a proper distance
from other vehicles to avoid sudden
braking. This will also reduce wear on
your brakes.

Avoid heavy traffic or traffic jams
whenever possible.

Do not rest your foot on the clutch
or brake pedal. This causes needless
wear, overheating and poor fuel econ-
omy.

Maintain a moderate speed on
highways. The faster you drive, the
greater the fuel consumption. By re-
ducing your speed, you will cut down
on fuel consumption.

Keep the front wheels in proper
alignment. Avoid hitting the curb and
slow down on rough roads. Improper
alignment not only causes faster tire
wear but also puts an extra load on the
engine, which, in turn, wastes fuel.

Keep the bottom of your vehicle
free from mud, etc. This not only
lessens weight but also helps prevent
corrosion.

Keep your vehicle tuned-up and in
top shape. A dirty air cleaner, improp-
er valve clearance, dirty plugs, dirty oil
and grease, brakes not adjusted, etc.
all lower engine performance and con-
tribute to poor fuel economy. For lon-
ger life of all parts and lower operating
costs, keep all maintenance work on
schedule, and if you often drive under
severe conditions, see that your ve-
hicle receives more frequent mainte-
nance (For scheduled maintenance in-
formation, please refer to the separate
Owner 's Manual Supplement/Main-
tenance Scheduleº).
CAUTION
Never turn off the engine to coast
down hills. Your power steering and
brake booster will not function with-
out the engine running. Also, the
emission control system operates
properly only when the engine is
running.!

(a) Simple checks137
IN CASE OF
AN EMERGENCY

If your vehicle will not start

If your engine stalls while
driving

If your vehicle overheats

If you have a flat tire

If your vehicle needs to be
towed

If you cannot shift automatic
transmission selector lever

If the convertible top does not
raise or lower

If you lose your keys
Before making these checks, make sure
you have followed the correct starting pro-
cedure given in How to start the engineº
in Part 3 and that you have sufficient fuel.
If the engine is not turning over or is
turning over too slowlyÐ
1. Check that the battery terminals are
tight and clean.
2. If the battery terminals are O.K.,
switch on the interior light.
3. If the light is out, dim or goes out when
the starter is cranked, the battery is dis-
charged. You may try jump starting. See
(c) Jump startingº for further instructions.
If the light is O.K., but the engine still will
not start, it needs adjustment or repair.
Call a Toyota dealer or qualified repair
shop.
NOTICE
Do not pull- or push-start the vehicle. It may damage the vehicle
or cause a collision when the enginestarts. Also the three-way catalyticconverter may overheat andbecome a fire hazard.
If the engine turns over at its normal
speed but will not startÐ
1. Check that all the push-on connec-
tors are tight. (For example, connections
at the spark plugs, ignition coil and/or dis-
tributor)
2. If the connectors are O.K., the engine
may be flooded because of repeated
cranking. See (b) Starting a flooded en-
gineº for further instructions.
ProCarManuals.com

138
If the engine will not start, your engine
may be flooded because of repeated
cranking.
If this happens, turn the key to STARTº
with the accelerator pedal held down.
Keep the key and accelerator pedal so for
15 seconds and release them. Then try
starting the engine with your foot off the
accelerator pedal.
If the engine does not start after 15 sec-
onds of cranking, release the key, wait a
few minutes and try again.
If the engine still will not start, it needs ad-
justment or repair. Call a Toyota dealer or
qualified repair shop for assistance.
NOTICE
Do not crank for more than 15 seconds at a time. This may
overheat the starter and wiringsystems.
To avoid serious personal injury and
damage to your vehicle which might
result from battery explosion, acid
burns, electrical burns, or damaged
electronic components, these instruc-
tions must be followed precisely.
If you are unsure about how to follow this
procedure, we strongly recommend that
you seek the help of a competent me-
chanic or towing service.

Batteries contain sulfuric acid
which is poisonous and corrosive.
Wear protective safety glasses
when jump starting, and avoid
spilling acid on your skin, cloth-
ing, or vehicle.

If you should accidentally get acid
on yourself or in you eyes, remove
any contaminated clothing and
flush the affected area with water
for at least 15 minutes. Then get
immediate medical attention. If
possible, continue to apply water
with a sponge or cloth while en
route to the medical office. CAUTION
!


The gas normally produced by a
battery will explode if a flame or
spark is brought near. Use only
standardized jumper cables and
do not smoke or light a match
while jump starting.
NOTICE
The battery used for boosting must be 12 V. Do not jump start unless
you are sure that the booster batteryis correct.
JUMP STARTING PROCEDURE
1. If the booster battery is installed in
another vehicle, make sure the vehicles
are not touching. Turn off all unnecessary
lights and accessories.
2. If required, remove all the vent plugs
from the booster and discharged batter-
ies. Lay a cloth over the open vents on the
batteries. (This helps reduce the explo-
sion hazard, personal injuries and burns.)
3. If the engine in the vehicle with the
booster battery is not running, start it and
let it run for a few minutes. During jump
starting, run the engine at about 2000 rpm
with the accelerator pedal lightly de-
pressed.
