The gauge works when the ignition
switch is on and indicates the approxi-
mate quantity of fuel remaining in the tank.
It is a good idea to keep the tank over 1/4 full.
The needle moves when braking, acceler-
ating or making turns. This is caused by the fuel moving in the tank.
If the level approaches Eº or the low fuel
level warning light comes on, fill the fuel
tank as soon as possible.
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.

The gauge works when the ignition
switch is on and indicates the approxi-
mate quantity of fuel remaining in the tank.
It is a good idea to keep the tank over 1/4 full.
This fuel gauge has a non-return typ
needle which remains at the last inidi-
cated 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.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, or
higher
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.

NOTICE
Do not remove the thermostat inthe 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 oil pressure gauge indicates en-
gine oil pressure when the ignition is
on. Check it while driving to make sure
that the needle is in the proper range.
If the oil pressure should stay below the
normal range, pull off the road to a safe
place to stop the engine immediately. Call
a Toyota dealer or qualified repair shop for
assistance.
Oil pressure may not build up when the oil
level is too low. The oil pressure gauge is not designed to indicate oil level, and the
oil level must be checked using the leveldipstick.
NOTICE
Do not drive the vehicle with oil pressure below the normal range
until the cause is fixed-it may ruin the engine.

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.
Two-wheel drive models-If the engine
coolant temperature is low, the transmis-
sion will not shift into the overdrive gear
even with the overdrive switch on. Four-wheel drive models-If the engine
coolant t
emperautre is low and the vehicle
is travelling at low speed or when the four-
wheel drive control lever is in L4º (four-
wheel drive, low range), the transmission
will not shift into the overdrive gear evenwith the overdrive switch on. (See Four-
wheel drive systemº in this Chapter for in-
formation of the four-wheel 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 dropsdown to or lower than the followingspeed, and more powerful engine
braking will be obtained.
Two-wheel drive models.Ð
3RZ-FE engine...112 km/h (70 mph)
5VZ-FE engine...117 km/h (73 mph)
Four-wheel drive models- ÐFour wheel drive control lever
in H2º and H4º...112 km/h (70 mph) ÐFour-wheel drive control lever in L4º...38 km/h (24 mph)
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 following speed, and
maximum engine braking will be ap- plied.
Two-wheel drive modelsÐ 3RZ-FE engine...54 km/h (34 mph)5VZ-FE engine...56 km/h (35 mph)
Four-wheel drive modelsÐ ÐFour-wheel drive control lever in H2º and H4º...54 km/h (34 mph)
ÐFour-wheel drive control lever in
L4º...10 km/h (6 mph)

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 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 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 (automatictransmission).
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 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 de-
pressed (manual), start the engine.
(With an automatic transmission, be
sure to keep the brake pedal de- pressed.)
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 ap- ply your brakes.
4. Have someone retrieve the blocks.

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
necessary, bring it up to half full again.
Serious coolant loss indicates a leak in
the system. You should have it
checked as soon as possible at your
Toyota dealer.
If your vehicle overheats

160Engine 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 when the engine is cold. 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. See Chapter 7-2 for additional information. Exhaust system
If you notice any change in the sound of
the exhaust or smell exhaust fumes, havethe 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

When the engine is running, keep
hands, clothing, and tools away
from the moving fan and engine
drive belts. (Removing rings,
watches, and ties is advisable.)
Right after driving, the engine
compartmentÐthe engine, radia-
tor, exhaust manifold, power steer-
ing fluid reservoir and spark plug
boots, etc.Ðwill be hot. So be care-
ful not to touch them. Oil, fluids
and spark plugs may also be hot.
If the engine is hot, do not remove
the radiator cap or loosen the drain
plugs to prevent burning yourself.
Do not smoke, cause sparks or al-
low open flames around fuel or the
battery. Their fumes are flamable.
Be extremely cautious when work-
ing on the battery. It contains poi-
sonous and corrosive sulfuric acid.
Do not get under your vehicle with
just the body jack supporting it. Al- ways use automotive jack stands
or other solid supports. CAUTION
!
Use eye protection whenever you
work on or under you vehicle
where you may be exposed to fly-
ing or falling material, fluid spray, etc.
Used engine oil contains poten-
tially harmful contaminants which
may cause skin disorders such as
inflammation or skin cancer, so
care should be taken to avoid pro-
longed and repeated contact with
it. To remove used engine oil from
your skin, wash thoroughly with
soap and water.
Do not leave used oil within thereach of children.
Dispose of used oil and filter only
in a safe and acceptable manner.
Do not dispose of used oil and fil-
ter in household trash, in sewers
or onto the ground. Call your deal- er or a service station for informa-
tion concerning recycling or dis- posal.
Remember that battery and igni-
tion cable carry high currents or
voltages. Be careful of accidental-
ly causing a short circuit.
Add only demineralized or dis-
tilled wa ter to fill the radiator. And
if you spill some of the coolant, be sure to wash it off with water to
prevent it from damaging theparts or paint.
Do not allow dirt or anything else
to fall through the spark plug
holes.
Do not pry the outer electrode of aspark plug against the center elec-
trode.
Use only spark plugs of the speci- fied type. Using other types will
cause engine damage, loss of per-
formance or radio noise.
Do not overfill automatic trans- mission fluid, or the transmission
could be damaged.
Do not drive with the air cleaner fil-ter removed, or excessive enginewear could result. Also backfiring
could cause a fire in the enginecompartment.
