ILLUMINATION CONTROL LOGIC
On some audio-units, when the instru-
ment panel lights are on, the letters on op-
erable buttons of the mode in current use
light up together with the mode selection and 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 youare 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 drifting 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 atmosphereÐespecially 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 froma 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.
ÐCar audio system operatinghints

11 2Use high-quality cassettes.
Low-quality cassette tapes can cause
many problems, including poor sound, inconsistent playing speed, and
constant auto-reversing. They can
also get stuck or tangled in the cas-
sette player.
Do not use a cassette if it has been
damaged or tangled or if its label is
peeling off.
Do not leave a cassette in the player if
you are not listening to it, especially if it is hot outside.
Store cassettes in their cases and out
of direct sunlight.
Avoid using cassettes with a total play-
ing time longer than 100 minutes (50
minutes per side). The tape used in
these cassettes is thin and could get
stuck or tangled in the cassette player.
CARING FOR YOUR COMPACT DISC
PLAYER AND DISCS Use only compact discs labeled as shown.
Extremely high temperatures can
keep your compact disc player from working. On hot days, use the air con-
ditioning to cool the vehicle interior be-
fore you listen to a disc.
Bumpy roads or other vibrations maymake your compact disc player skip.
If moisture gets into your compact disc
player, you may not hear any sound even though your compact disc player
appears to be working. Remove thedisc from the player and wait until itdries.
Handle compact discs carefully, espe-
cially when you are inserting them.
Hold them on the edge and do not
bend them. Avoid getting fingerprints
on them, particularly on the shiny side.
Dirt, scrapes, warping, pin holes, or
other disc damage could cause the
player to skip or to repeat a section of
a track. (To see a pin hole, hold the disc
up to the light.)
Remove discs from the compact disc
player when you are not listening to
them. S tore them in their plastic cases
away from moisture, heat, and directsunlight.
To clean a compact disc: Wipe it with a
soft, lint-free cloth that has been damp-
ened with water. Wipe in a straight line
from the center to the edge of the disc (not
in circles). Dry it with another soft, lint-
free cloth. Do not use a conventional re-cord cleaner or anti-static device.

If your engine knocks...
If you detect heavy knocking even when
using the recommended fuel, or if you
hear steady knocking while holding a
steady sp
eed on level roads, consult your
Toyota dealer.
However, now and then, you may notice
light knocking for a short time while accel-
erating or driving up hills. This is no cause
for concern.
GASOLINES CONTAINING DETER-
GENT ADDITIVES
Toyota recommends use of gasolines
that contain detergent additives to
avoid build-up of engine deposits.
For further details, ask your Toyota dealer
or a local gasoline retailer.
GASOLINES CONTAINING MTBE
Gasolines that contain MTBE (Methyl
Tertiary-Butyl Ether) are available in
the market. If you use a gasoline mixed
with MTBE, make certain that it does
not contain more than 15% of MTBE.
If the use of gasolines containing MTBE causes poor driveability and/or poor fuel
economy, you should discontinue the use
of fuels containing MTBE. GASOLINES CONTAINING ALCOHOL
If you use gasohol in your Toyota, be sure that it is unleaded, has an octane
rating no lower than 87 and does not
contain more than 10% ethanol.
Gasohol is a
mixture of gasoline and etha-
nol.
Toyota does not recommend the use of
gasolines containing m ethanol. If you use
gasoline containing methanol, use only
gasoline meeting the requirements above
and also containing less than 5% metha-
nol with cosolvents and corrosion inhibi-
tors for methanol.
NOTICE
Do not use gasohol other than
stated above. It will cause fuel
system damage or vehicle per-formance problems.
If driveability problems are en-
countered (poor hot starting, va- porizing, engine knock, etc.),discontinue the use.
Take care not to spill gasohol
during refueling. Gasohol maycause paint damage.
FUEL TANK CAPACITY
70 L (18.5 gal., 15.4 Imp. gal.)

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 reservevacuum for one or two stopsÐbut no more!
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 hardÐmuch harder than nor-
mal. And your braking distance will
be longer.
ANTI-LOCK BRAKE SYSTEM (with ABSº warning light)
The anti-lock brake system is designed to prevent lock-up of the wheels during sud-
den braking or braking on slippery road surfaces. This assists the driver in con-
trolling the vehicle under these circum-stances.
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
approximately 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 vehicleis started. This means that the anti-lock
brake system is in the self check mode,
and does not indicate a malfunction.

When the anti-lock brake system function is in action, you may feel the brake pedal
pulsating and hear a noise. In this situa-
tion, to let the anti-lock brake system work for you, just hold the brake pedal
down
more firmly. Do not pump the brake.
The brake pedal pulsation caused by the
anti-lock brake system may indicate haz- ardous road surface conditions. Althoughthe anti-lock brake system assists in pro-
viding vehicle control, it is still important to
drive with all due care, because the anti-
lock brake system cannot overcome the
laws of physics that act on your vehicle: Braking capab ility is dependent on tire
friction with the road surface.
Even though the anti-lock brake sys-
tem is operating, a driver cannot main- tain full control on certain slippery road
surfaces, when cornering at highspeeds, or in violent maneuvers.
Avoid high speeds on wet roads. The
anti-lock brake system cannot elimi-
nate the risk of hydroplaning and lossof tire friction. Always maintain a safe distance from the
vehicle in
front of you. Compared with ve-
hicles not fitted with an anti-lock brake
system, your vehicle may require a longer
stopping distance in the following cases: Driving on rough, gravel or snow-cov-
ered roads.
Driving with tire chains installed.
Driving on roads where the road sur-
face is pitted or has other differencesin surface height.
CAUTION!
Do not use tires other than the
manufacturer 's designated tires,
and do not mix tires or wheels of dif-
ferent sizes. You may prevent the an-
tilock brake system from operatingat full effectiveness.
Vehicles with rear differential lock sys-
temÐThe anti-lock brake system does
not operate when the rear differential islocked. It is normal operation for the
ABSº warning light to be on at this time.Type A
Type B

135
ABSº warning light
This light comes on when the ignition key is turned to the ONº position. After about
3 seconds, the light will go off.
When the light is on with the rear dif
feren-
tial locked, it indicates the anti-lock brake
system will not operate.
If either of the following conditions occurs, this indicates a malfunction somewhere inthe parts monitored by the warning light
system. Contact your Toyota dealer as
soon as possible to service the vehicle. The light does not come on as de-
scribed above, or remains on.
The light comes on while driving with
the rear differential unlocked.
The light does not come on with the
rear differential locked.
The light comes on while driving.
Even if the anti-lock brake system should
fail, the brake system will still operate con-
ventionally. Have your vehicle checked by
your Toyota dealer as soon as possible.
The brake pad wear limit indicators on your disc brakes give a warning noise
when the brake pads are worn to
where replacement is required.
If you hear a squealing or scraping noise
while driving, have the brake pads
checked and replaced by your Toyota
dealer as soon as possible. Expensive ro-
tor damage can result if the pads are not
replaced when necessary. When stowing luggage or cargo in the ve-
hicle, observe the following:
Put luggage or cargo in the luggage
compartment when at all possible. Besure all items are secured in place.
Be careful to keep the vehicle bal-anced. Locating the weight as far
forward as possible helps maintainbalance.
For better fuel economy, do not carry
unneeded weight.CAUTION!
To prevent luggage or packages
from sliding forward during brak-
ing, do not stack anything in the
luggage compartment higher than
the seatbacks. Keep luggage or
packages low, as close to the floor
as possible.
Never allow anyone to ride in the
luggage compartment. It is not de-
signed for passengers. They
should ride in their seats with their
seat belts properly fastened.
Otherwise, they are much more
likely to suffer serious bodily inju-
ry, in the event of sudden braking or a collision.
