ment panel lights are on, the letters on op-
erable buttons of the mode in current use
light up together with the mode selectionand eject buttons. RADIO RECEPTION
Usually, a problem with radio reception
does not mean there is a problem with
your radioÐit is just the normal result of
conditions outside the vehicle.
For example, nearby buildings and terrain
can interfere with FM reception. Power
lines or telephone wires can interfere with
AM signals. And of course, radio signals
have a limited range, and the farther you are from a station, the weaker its signal
will be. In addition, reception conditions
change constantly as your vehicle moves. Here are some common reception prob-lems
that probably do not indicate a prob-
lem with your radio: FM
Fading and driving stationsÐGenerally,
the effective range of FM is about 40 km
(25 miles). Once outside this range, you
may notice fading and drifting, which in- crease with the distance from the radio
transmitter. They are often accompanied by distortion.
Multi-pathÐFM signals are reflective,
making it possible for two signals to reach
your antenna at the same time. If this hap-
pens, the signals will cancel each other
out, causing a momentary flutter or loss of
reception.
Static and flutteringÐThese occur when
signals are blocked by buildings, trees, or other large objects. Increasing the bass
level may reduce static and fluttering.
Station swappingÐIf the FM signal you are listening to is interrupted or weak-
ened, and there is another strong station
nearby on the FM band, your radio may
tune in the second station until the original
signal can be picked up again. AM FadingÐAM broadcasts are reflected by the upper atmosphere-especially atnight. These reflected signals can inter-
fere with those received directly from the radio station, causing the radio station tosound alternately strong and weak.
Station interferenceÐWhen a reflected
signal and a signal received directly from a radio station are very nearly the same
frequency, they can interfere with each
other,
making it difficult to hear the broad-
cast.
StaticÐAM is easily affected by external sources of electrical noise, such as high
tension power lines, lightening, or electri-cal motors. This results in static.
CARING FOR YOUR CASSETTE PLAY-
ER AND TAPES
For high performance from your cassette
player and tapes:
Clean the tape head and other parts regu-
larly. A dirty tape head or tape path can de-
crease sound quality and tangle your
cassette tapes. The easiest way to
clean them is by using a cleaning tape.
(A wet type is recommended.)

CIGARETTE LIGHTER
To use the cigarette lighter, press it in.
When it becomes heated, it automati-
cally pops out ready for use.
If the engine is not running, the key must be in the ACCº position.
Do not hold the cigarette lighter pressed in.
Use a Toyota genuine cigarette lighter or equivalent for replacement.ASHTRAY
To use the ashtray, pull it out. When finished with your cigarette, thor-
oughly extinguish it in the ashtray to pre-
vent other cigarette butts from catching
fire. After using the
ashtray, close the ash-
tray cover completely.
To remove the ashtray, press down on the lock spring plate and pull out.To reduce the chance of injury in
case of an accident or sudden stop
while driving, always close theashtray cover completely after use. CAUTION

CAUTION!
When driving off-road or in rugged
terrain, do not drive at excessive
speeds, jump the vehicle, or strike
objects, etc. This may cause loss of
control or vehicle rollover. You are
also risking expensive damage to
your vehicle's suspension and chassis. 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).
Run the engine at moderate speed be- tween 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.
Do not tow a trailer during the first 800
km (500 miles) 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 opening.
The special nozzle on pumps with unleaded
fuel will fit it, but the larger standard nozzle
on pumps with leaded gas will not.
Do not use leaded gasoline. Use of
leaded gasoline will cause the
three-way catalytic converter tolose its effectiveness and the emis- sion control system to function im-properly. Also, this can increase maintenance costs.
NOTICE
OCTANE NUMBER
Select Research Octane Number 91 (Oc-
tane Rating 87) or higer.
Use of unleaded fuel with an octane num- ber or rating lower than stated above will
cause persistant heavy knocking. If se-
vere, this will lead to engine damage.

Your engine is fitted with twin ground electrode spark plugs.
NOTICE
Use only twin ground electrode spark plugs for your engine perfor-
mance.
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 fa il, the other will 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.
CAUTION!
Do not drive your vehicle with only a single brake system. Have your
brakes fixed immediately.
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 reserve
vacuum for one or two stops - but nomore!
CAUTION!
Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your vacuum re- serve.
Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push
the pedal hard-much harder than
normal. And your braking dis- tance will be longer
ANTI-LOCK BRAKE SYSTEM (with ABSº warning light)
The anti- lock brake system is designed to
automatically help prevent lock- up of the
wheels during sudden braking or braking on
slippery road surfaces. This assists in pro-
viding directional stability and steering per -
formance of the vehicle under these cir -
cumstances.
The anti- lock brake system becomes op-
erative after the vehicle has accelerated to
a speed in excess of approximately 10 km/h
(6 mph). It stops operating when the vehicle
decelerates to a speed below approximate-
ly 5 km/h (3 mph).
You may hear a sound in the engine
compartment for a few seconds when the
engine is started or just after the vehicle is started. This means that the anti-lock
brake system is in the self check mode,
and does not indicate a malfunction.

Four-wheel drive modelsÐToyota
recommends not using four-wheel
drive on dry hard-surfaced roads, be-
cause four-wheel driving will cause unnecessary noise and wear, and poor
fuel economy.
Four-wheel drive modelsÐIn cold
temperatures, noise may occur when
driving in two-wheel drive before the
transfer is warmed up. Therefore, first
drive in four-wheel drive until the
transfer is warmed up.
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, 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 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. When driving your vehicle off-road,
please observe the following precautions
to ensure your driving enjoyment and to
help prevent the closure of areas to off-
road vehicles.
a. Drive your vehicle only in
areas where
off-road vehicles are permitted to travel.
b. Respect private property. Get owner's
permission before entering private prop-
erty.
c. Do not enter areas that are closed.
Honor gates, barriers and signs that re-
strict travel.
d. Stay on established roads. When con-
ditions are wet, driving techniques should
be changed or travel delayed to prevent
damage to roads.
For owners in U.S. mainland, Hawaii and Puerto Rico:
To obtain additional information pertaining
to driving your vehicle off-road, consult the following organizations. State and Local Parks and Recreation Departments

Your vehicle is designed primarily as a
passenger - and - load - carrying vehicle.
Towing a trailer will have an adverse ef
fect
on handling, performance, braking, dura-
bility and driving economy (fuel consump-
tion, etc.). Your safety and satisfaction de-
pend on the proper use of correct
equipment and cautious driving habits.
For your safety and the safety of others,you must not overload your vehicle or
trailer. Ask your local T oyota dealer for fur-
ther details before towing. WEIGHT LIMITS
Before towing, make sure the total
trailer weight, gross combination
weight, gross vehicle weight, grossaxle weight and trailer tongue load are
all within the limits.
The total trailer weight and tongue load
can be measured with platform scales
found at a highway weighing station,
building supply company, trucking com-
pany, junk yard, etc.
CAUTION!
The total trailer weight (trailer
weight plus its cargo load) must
not exceed the following. Exceed-
ing this weight is dangerous. If
towing a trailer over 907 kg (2000lb.), it is necessary to use a sway
control device with a sufficient ca-
pacity.
3RZ-FE engines 1587 kg (3500 lb.)
5VZ-FE engine
2267 kg (5000 lb.)
The gross combination weight
(sum of your vehicle weight plus
its load and the total trailer weight)
must not exceed the following.
Two-wheel drivemodels
3RZ-FE engine
3447 kg (7600 lb.)
5VZ-FE engine
3992 kg (8800 lb.)
Four-wheel drive models 3RZ-FE engine 3583 kg (7900 lb.)
5VZ-FE engine 4173 kg (9200 lb.)
The gross vehicle weight must not
exceed the Gross Vehicle Weight
Rating (GVWR) indicated on the
Certification Label. The gross ve-
hicle weight is the sum of weights
of the unloaded vehicle, driver,
passengers, luggage, hitch and
trailer tongue load. It also includes
the weight of any special equip-
ment installed on your vehicle.
The load on either the front or rearaxle resulting from distribution of
the gross vehicle weight on both axles must not exceed the Gross
Axle Weight Rating (GAWR) listed on the Certification Label.
Trailer towing

Avoid continuous speeding up and
slowing down. Stop-and-go driving
wastes fuel.
Avoid unnecessary stopping andbraking. 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 preventcorrosion.
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 isrunning.

Two-wheel drive modelsFour-wheel drive modelsIf towing is necessary, we recommend
you to have it done by your Toyota
dealer or a commercial tow truck ser-
vice. In consultation with them, have
your vehicle towed using either (a) or(b).
Only when you cannot receive a tow-
ing service from a Toyota dealer or
commercial tow truck service, tow
your vehicle carefully in accordance
with the instructions given in
ÐEmergency towingº in this part. Proper equipment will help ensure that your vehicle is not damaged while being
towed. Commercial operators are gener-
ally
aware of the state/provincial and local
laws pertaining to towing.
Your vehicle can be damaged if it is towed
incorrectly. Although most operators know the correct procedure, it is possible
to make a mistake. To avoid damage to your vehicle, make sure the following few
precautions are observed. If necessary,
show this page to the tow truck driver.
