With Tachometer
Without Tachometer 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.

58
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.

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, thetransmission will not shift into overdrive
gear even with the overdrive switch on.
Never put your foot on the accelerator 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 lowerthan 106 km/h (66 mph). The trans- mission will downshift to the second
gear and more powerful engine brak-
ing will be obtained.
Shift into the Lº position when the ve-
hicle speed drops down to or lower than 61 km/h (38 mph). The transmis- sion will downshift to the first gear and
maximum engine braking will be ap- plied. Vehicles with cruise controlÐWhen the
cruise control is being used, even if you
downshift the transmission by turning off
the overdrive switch, engine braking is not
applied because the cruise control is not cancelled. For ways to decrease the ve-
hicle speed, see Cruise controlº in this
chapter.
Be careful when downshifting on a
slippery surface. Abrupt shifting
could cause the vehicle to spin orskid.
CAUTION
!
(c) Using the 2º and Lº positions
The 2º and Lº positions are used for
strong engine braking as described pre-
viously. With the selector lever in 2º or Lº, you
can start the vehicle in motion as with the
lever in Dº. With the selector lever in 2º, the vehicle
will start in the first gear and automatically
shift to the second gear.
With the selector lever in Lº, the trans-
mission is engaged in the first gear.

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

Backing w ith a trailer is difficult and re-
quires practice. Grip the bottom of the steering wheel and move your hand to
the left to move the trailer to the left. Move your hand to the right to move
the trailer to the right. (This procedureis generally opposite to that when
backing without a trailer). Also, just
turn the steering wheel a little at a time,
avoiding sharp or prolonged turning. Have someone guide you when back-
ing to reduce the risk of an accident.
Because stopping distance may be in-
creased, vehicle-to-vehicle distance
should be increased when towing a
trailer. For each 16 km/h (10 mph) of speed, allow at least one vehicle and
trailer length between you and the ve-
hicle ahead. Avoid sudden braking as you may skid, resulting in jackknifing and loss of control This is especially
true on wet or slippery surfaces.
Avoid jerky starts or sudden accelera-tion. If your vehicle has manual trans-
mission, prevent excessive clutch slip-
page by keeping engine rpm low and
not racing the engine. Always start out
in first gear.
Avoid jerky steering and sharp turns.
The trailer could hit your vehicle in a
tight turn. Slow down before making a
turn to avoid the necessity of sudden braking.
Remember that when making a turn,the trailer wheels will be closer than the vehicle wheels to the inside of the
turn. Therefore, compensate for this
by making a larger than normal turning
radius with your vehicle.
Crosswinds and rough roads will ad-
versely affect handling of your vehicle
and trailer, causing sway. Pay atten-
tion to the rear from time to time to pre-
pare yourself for being passed by largetrucks 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 sta-bilize.
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 (automatic transmission).
Because of the added load of the trail-
er, your vehicle's engine may overheat
on hot days (at temperatures over 30 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 of this 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 onlyafter 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.

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 ve- hicle and turn on your emergency
flashers. Put the transmission in Pº
(automatic) or neutral (manual) and
apply the parking brake. Turn off the
air conditioning if it is being used.
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 ve-
hicle. However, note that water drain-ing from the air conditioning 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 of the coolant is leaking, stop the engine im-
mediately. Call a Toyota dealer for as- sistance.
5. If The engine drive belt is O.K. and there are no obvious leaks, you may
help the engine cool down more quick-
ly 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
engine is running. Fill it about half full.
Do not attempt to remove the
radiator cap when the engine and
radiator are hot. Serious injury
could result from scalding hot fluid
and steam blown out underpressure. CAUTION
!
7. After the engine coolant temperature has cooled to normal, again check the
coolant level in the reservoir. If neces-
sary, bring it up to half full again. Seri-
ous coolant loss indicates a leak in the
system. You should have it checked as
soon as possible at your Toyota deal-
er.
If your vehicle overheats

mech-
anism
Check the lock release button of the se-
lector lever for proper and smooth opera-
tion. On a safe incline, check that your ve-
hicle is held securely with the selector lever in ºPº position and all brakes re- leased.
IN THE ENGINE COMPARTMENT Items listed below should be checked
from time to time , e.g. each time when
refueling.
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 when the engine is cold.
See Chapter 7-2 for additional informa-tion.
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 informa- tion.
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. SeeChapter 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 drivingstraight 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
Does your vehicle need repairing?
