Service reminder indicators and warning buzzers
The gauge works when the ignition
switch is on
and indicates the approxi-
mate quantity of fuel remaining in the tank. Nearly fullÐNeedle at Fº Nearly emptyÐNeedle at Eº
It is a good idea to keep the tank over 1/4 full.
This fuel gauge has a non-return type
needle wh ich remains at the last indicated
position when the ignition switch is turned
off.
If the level approaches Eº or the low fuel
level warning light (on some models)
comes on, fill the fuel tank as soon as pos- sible. 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 assoon as possible.

48
The gauge indicates the engine cool-
ant temperature when the ignition
switch is on. The engine operating
temperature will vary with changes inweather and engine load.
If the needle moves into the red zone, your engine is too hot. If your vehicle over-
heats, stop your vehicle and allow the en-
gine 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 (revolutions per
minute). Use it while driving to select
correct shift points and to prevent en-
gine lugging and overr evving.
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.

Your automatic transmission has a shift
lock system to minimize the possibility of
incorrect operation. This means you can
only shift out of Pº position when the brake
pedal is depressed (with the ignition
switch in ONº position and the selector le- ver pulled toward you).
(a) Normal Driving
1. Start the engine as instructed in How
to start the engineº in Part 3. The trans- mission must be in Pº or Nº.
2. With your foot holding down the brake
pedal, shift the selector lever to Dº.
In Dº position, the automatic transmis-
sion system will select the most suitable
gear for running conditions such as nor-
mal cruising, hill climbing, hard towing, etc.
Always turn the overdrive switch on for
better fuel economy and quieter driving. If
the engine coolant temperature is low, the transmission will not shift into overdrive
gear even with the overdrive switch on.
Never put your foot on the accelera-
tor pedal while shifting. CAUTION
! 3. Release the parking brake and brake
pedal. Depress the accelerator pedal
slowly for smooth starting.
(b) Using engine braking
To use engine braking, you can downshift the transmission as follows:
Turn off the overdrive switch. The O/D
OFFº indicator light will come on and the transmission will downshift to the
third gear.
Shift into the 2º position when the ve-
hicle speed drops down to or lower than the maximum allowable speed for
second gear. The transmission will downshift to the second gear andmore powerful engine braking will beobtained.
Shift into the Lº position when the ve-
hicle speed drops down to or lower than the maximum allowable speed for
Lº position. The transmission will
downshift to the first gear and maxi-
mum engine braking will be applied.
Vehicles with cruise controlÐWhen the
cruise control is being used, even if you
downshift the transmission by turning off the overdrive switch, engine braking will
not be applied because the cruise control
is not cancelled. For ways to decrease the
vehicle speed, see Cruise controlº in this
chapter. MAXIMUM ALLOWABLE SPEEDS
2º 124 km/h (77 mph)
. . . . . . . . . . . .
Lº 72 km/h (45 mph) . . . . . . . . . . . . .
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to spin orskid. CAUTION
!
NOTICE
To prevent engine overrevving, do
not downshift if you are going
faster than the above speed ineach position.
Be careful not to overrev the en-
gine. Watch the tachometer tokeep engine rpm from going intothe red zone. The approximate
maximum allowable speed for each position is given above foryour reference.
Do not continue hill climbing for a
long time in the 2º or Lº posi-tion. This may cause severe auto-
matic transmission damage fromoverheating. To prevent suchdamage, use Dº position for hill
climbing or hard towing.

58Your automatic transmission has a shift
lock system to minimize the possibility of
incorrect operation. This means you can
only shift out of Pº position when the brake
pedal is depressed (with the ignition
switch in ONº position and the selector le- ver pulled toward you).
(a) Normal driving
1. Start the engine as instructed in How
to start the engineº in Part 3. The trans- mission must be in Pº or Nº.
2. With your foot holding down the brake
pedal, shift the selector lever to Dº.
In Dº position, the automatic transmis-
sion system will select the most suitable
gear for running conditions such as nor-
mal cruising, hill climbing, hard towing, etc.
Always turn the overdrive switch on for
better fuel economy and quieter driving. If
the engine coolant temperature is low, the transmission will not shift into the over-
drive gear even with the overdrive switch on.
Never put your foot on the accelera-
tor pedal while shifting. CAUTION
!
3. Release the parking brake and brake
pedal. Depress the accelerator pedal
slowly for smooth starting. (b) Using engine braking
To use engine braking, you can downshift the transmission as follows:
Turn off the overdrive switch. The O/D
OFFº indicator light will come on and the transmission will downshift to the
third gear.
Shift into the 2º position. The trans-
mission will downshift to the second
gear when the vehicle speed drops
down to or lower than the maximum al-
lowable speed for second gear, andmore powerful engine braking will beobtained.
Shift into the Lº position. The trans- mission will downshift to the first gear
when the vehicle speed drops down to
or lower than the maximum allowable
speed for Lº position and maximum
engine braking will be applied.
Vehicles with cruise controlÐWhen the
cruise control is being used, even if you
downshift the transmission by turning off the overdrive switch, engine braking will
not be applied because the cruise control
is not cancelled. For ways to decrease the
vehicle speed, see Cruise controlº in this
chapter.
MAXIMUM ALLOWABLE SPEEDS
2º 136 km/h (85 mph) . . . . . . . . . . . .
Lº 74 km/h (46 mph) . . . . . . . . . . . . .
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to spin orskid. CAUTION
!
NOTICE
Be careful not to overrev the en-
gine. Watch the tachometer to
keep engine rpm from going into
the red zone. The maximum allow-able speed (approximate) for each
position is given above for yourreference.
Do not continue hill climbing for along time in the 2º or Lº posi-
tion. This may cause severe auto-matic transmission damage from
overheating. To prevent such damage, use Dº position for hillclimbing or hard towing.
(c) 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.

Your automatic transmission has a shift
lock system to minimize the possibility of
incorrect operation. This means you can
only shift out of Pº position when the brake
pedal is depressed (with the ignition
switch in ONº position and the lock re-
lease button depressed).
(a) Normal driving
1. Start the engine as instructed in How
to start the engineº in Part 3. The trans- mission must be in Pº or Nº.
When the front drive control lever is in L4º
(low-speed position, four-wheel drive),
the driving pattern selector setting has no
effect on gear shift timing. (See Four-
wheel drive systemº in this Chapter for in-
formation of the front drive control lever.)
2. With your foot holding down the brake
pedal, shift the selector lever to Dº.
In Dº position, the automatic transmis-
sion system will select the most suitable
gear for running conditions such as nor-
mal cruising, hill climbing, hard towing, etc. Always turn the overdrive switch on for
better
fuel economy and quieter driving. If
the engine coolant temperature is low or
when the front drive control lever is in L4º
(low-speed position, four-wheel drive),
the transmission will not shift into the
overdrive gear even with the overdrive
switch on. (See Four-wheel drive sys-
temº in this Chapter for information of the
front drive control lever.)
Never put your foot on the accelera-
tor pedal while shifting. CAUTION
!
3. Release the parking brake and brake
pedal. Depress the accelerator pedal
slowly for smooth starting.
(b) Using engine braking
To use engine braking, you can downshift the transmission as follows: Turn off the overdrive switch. The O/D
OFFº indicator light will come on andthe transmission will downshift to the
third gear.
Shift into the 2º position. The trans-
mission will downshift to the second
gear when the vehicle speed drops
down to or lower than the maximum
allowable speed for second gear, and more powerful engine braking will be obtained.
Shift into the Lº position. The trans- mission will downshift to the first gear
when the vehicle speed drops down to
or lower than the maximum allowable
speed for Lº position and maximum
engine braking will be applied.
Vehicles with cruise controlÐWhen the
cruise control is being used, even if you
downshift the transmission by turning off the overdrive switch, engine braking will
not be applied because the cruise control
is not cancelled. For ways to decrease the
vehicle speed, see Cruise controlº in this
chapter.

Crosswinds and rough roads will ad-
versely affect handling of your vehicle
and trailer, causing sway. Pay attention
to the rear from time to time to prepare
yourself for being passed by large
trucks or buses, which may cause your
vehicle and trailer to sway. If swaying
happens, firmly grip the steering wheel
and reduce speed immediately but
gradually. Never increase speed. Steer
straight ahead. If you make no extreme
correction with the steering or brakes,
the vehicle and trailer will stabilize.
Be careful when passing other ve- hicles. Passing requires considerable
distance. After passing a vehicle, do
not forget the length of your trailer and
be sure you have plenty of room be-
fore changing lanes.
In order to maintain engine braking ef-
ficiency, do not use fifth gear (manual
transmission) or overdrive (automatictransmission).
Because of the added load of the trail-
er, your vehicle's engine may overheat
on hot days (at temperatures over30 5C [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 ofthis manual.
Always place wheel blocks under both
the vehicle and trailer wheels whenparking. 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 firmly.
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 thebrake 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 wheel 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 usual-
ly increases as the speed in-
creases, exceeding 72 km/h (45
mph) may cause loss of control.
Slow down and downshift before
descending steep or long down-
hill grades. Do not make suddendownshifts.
Avoid holding the pedal down too
long or too frequently. This could
cause the brakes to overheat and
result in reduced braking efficiency.
CAUTION!

122If your engine stalls while driving
0
1. Reduce your speed gradually, keeping
a straight line. Move cautiously off the
road to a safe place.
2. Turn on your emergency flashers.
3. Try starting the engine again.
If the engine will not start, see If your ve-
hicle will not startº.
If the engine is not running, the
power assist for the brakes and
steering will not work so steering
and braking will be much harder
than usual. CAUTION
! If your engine coolant temperature
gauge indicates overheating, if you
experience a loss of power, or if you
hear a
loud knocking or pinging noise,
the engine has probably overheated.
You should follow this procedure 0
1. Pull safely off the road, stop the vehicle
and turn on your emergency flashers. Put
the transmission in Pº (automatic) or neu-
tral ( manual) and apply the parking brake.
Turn off the air conditioning if it is beingused.
2. If coolant or steam is boiling out of the
radiator or reservoir, stop the engine. Wait
until the steam subsides before opening
the hood. If there is no coolant boiling over or steam, leave the engine running.
To help avoid personal injury, keep
the hood closed until there is no steam. Escaping steam or coolant is
a sign of very high pressure. CAUTION
!
3. Visually check to see if the engine drive
belt (fan belt) is broken or loose. Look for
obvious coolant leaks from the radiator,
hoses, and under the vehicle. However, note that water draining from the air condi-
tioning is normal if it has been used.
When the engine is running, keep
hands and clothing away from the
moving fan and engine drive belts. CAUTION
!
4. If the engine drive belt is broken or the
coolant is leaking, stop the engine immedi-
ately. Call a Toyota dealer for assistance.
5. If the engine drive belt is O.K. and there
are no obvious leaks, you may help the en-
gine cool down more quickly by running it at
about 1500 rpm for a few minutes with the
accelerator pedal lightly depressed.
6. Check the coolant reservoir. If it is dry,
add coolant to the reservoir while the en- gine is running. Fill it about half full.
Do not attempt to remove the radia-
tor cap when the engine and radia-
tor are hot. Serious injury could re-
sult from scalding hot fluid and
steam blown out under pressure. CAUTION
!
7. After the engine coolant temperature
has cooled to normal, again check the
coolant level in the reservoir. If necessary,
bring it up to half full again. Serious cool- ant loss indicates a leak in the system.
You should have it checked as soon as
possible at your Toyota dealer.

144IN THE ENGINE COMPARTMENT Items listed below should be checked
from time to time, e.g. each time whenrefueling.
Washer fluid
Make sure there is sufficient fluid in the
tank. See Chapter 7-3 for additional
infor-
mation.
Engine coolant level
Make sure the coolant level is between the
FULLº and LOWº lines on the see-
through reservoir. See Chapter 7- 2 for
additional information. Battery electrolyte level Make sure the electrolyte level of all bat-
tery cells is between upper and lower level
lines on the case. Add only distilled water
when replenishing. See Chapter 7-3 for
additional information. Brake fluid level
Make sure the brake fluid level is correct.
See Chapter 7- 2 for additional information.
Engine oil level
Check the l evel on the dipstick with the en-
gine turned off and the vehicle parked on
a level spot. See Chapter 7-2 for addition-
al information. Power steering fluid level Check the level on the dipstick. The level
should be in the HOTº or COLDº range
depending on the fluid temperature. See Chapter 7-2 for additional information. Exhaust system
If you notice any change in the sound of
the exhaust or smell exhaust fumes, have the cause located and corrected immedi-
ately. (See engine exhaust cautions in
Part 2.)
Be on the alert for changes in perfor-
mance, sounds, and visual tip-offs
that in-
dicate service is needed. Some important
clues are as follows: Engine missing, stumbling, or pinging
Appreciable loss of power
Strange engine noises
A leak under the vehicle (however, wa-
ter dripping from the air conditioning
after use is normal.)
Change in exhaust sound (This may
indicate a dangerous carbon monox-
ide leak. Drive with the windows open
and have the exhaust system checked
immediately.)
Flat-looking tire; excessive tire squeal
when cornering; uneven tire wear
Vehicle pulls to one side when driving straight on a level road
Strange noises related to suspensionmovement
Loss of brake effectiveness; spongy
feeling brake or clutch pedal; pedal al-
most touches floor; vehicle pulls to one
side when braking
Engine coolant temperature continual-
ly higher than normal
