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 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 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 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 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.
(A wet type is recommended.)
ÐCar audio system operating hints

96Use 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.

To operate the cigarette lighter, press
it in. When it becomes heated, it auto-
matically 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. 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.
Use a Toyota genuine cigarette lighter or equivalent for replacement.
To reduce the chance of injury in
case of an accident or sudden stop while driving, always push the ash-tray back in completely after using. CAUTION
!
To open the glovebox door, pull the
lever.
On some models, the glovebox light will
come on when the door is open with the
headlight switch on.
To reduce the chance of injury in
case of an accident or sudden stop,
always keep the glovebox door
closed while driving.

OCTANE NUMBER
Select Research Octane Number 91
(Octane Rating 87) or higher.
Use of unleaded fuel with an octane num- ber or rating lower than stated above will
cause persistent heavy knocking. If se-
vere, this will lead to engine damage. 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 d riving 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 u
nleaded, 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 solvents and corrosion inhibitorsfor methanol.
Do not use gasohol other than
stated above. It will cause fuel
system damage or vehicle perfor-
mance problems.
If driveability problems are en- countered (poor hot starting, va-
porizing, engine knock, etc.), dis-continue the use.
Take care not to spill gasohol dur-
ing refueling. Gasohol may causepaint damage.

The diluting ingredients evaporate out
when the vehicle is then driven at high
speeds, as on an expressway, making itappear that oil is excessively consumed
after driving as high speeds.
IMPORTANCE OF ENGINE OIL LEVEL CHECK
One of the most important points in proper vehicle maintenance is to keep the engine
oil at the optimum level so that oil function
will
not be impaired. Therefore, it is essen-
tial that the oil level be checked regularly.
Toyota recommends that the oil level bechecked every time you refuel the vehicle.
Failure to check the oil level
regularly could lead to serious
engine trouble due to insufficient oil.
NOTICE
For detailed information on the oil level
check, see Checking the engine oil levelº
in Chapter 7-2.
Your engine is fitted with twin ground elec- trode spark plugs.
Use only twin ground electrode
spark plugs for your engine
performance.
NOTICE
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 fail, the other w ill 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 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 hard-much 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 automatically prevent lock-up of the
wheels during sudden braking or braking on slippery road surfaces. This assists in
providing directional stability and steeringperformance of the vehicle under these circumstances.
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 vehicle is started. This means that the anti-lock
brake system is in the self check mode,
and does not indicate a malfunction.
Effective way to press the ABSº brake
pedal: When the anti-lock brake system
function is in action, you may feel the brake pedal pulsating and hear a noise.
In this situation, to let the anti-lock brake
system work for you, just hold the brake
pedal down more firmly. Do not pumpthe brake. This will result in reduced
braking performance.
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 c apability 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 loss of 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 different
sizes. You may prevent the antilock brake system from operating at full effectiveness.
