This section describes some of the basic
features on Toyota audio systems. Some
information may not pertain to your sys-
tem.
Your audio system works when the ignition
key is in the “ACC” or “ON” position.
TURNING THE SYSTEM ON AND OFF
Push “PWR·VOL” to turn the audio system
on and off.
Push “AM”, “FM”, “FM1”, “FM2”, “TAPE”,
“DISC” or “LOAD” to turn on that function
without pushing “PWR·VOL”. To turn on
the cassette or compact disc player, a
cassette or compact disc must be loaded
in the player.
You can turn on each player by inserting
a cassette tape or compact disc.
You can turn off each player by ejecting
the cassette tape or compact disc. If the
audio system was previously off, then the
entire audio system will be turned off
when you eject the cassette tape or com-
pact disc. If another function was pre-
viously playing, it will come on again.
SWITCHING BETWEEN FUNCTIONS
Push “AM”, “FM”, “FM1”, “FM2”, “TAPE”,
“DISC” or “LOAD” if the system is already
on but you want to switch from one func-
tion to another. TONE AND BALANCE
For details about your system’s tone and
balance controls, see the description of
your own system.
Tone
How good an audio program sounds to
you is largely determined by the mix of
the treble, midrange, and bass levels. In
fact, different kinds of music and vocal
programs usually sound better with differ-
ent mixes of treble, midrange and bass.
Balance
A good balance of the left and right stereo
channels and of the front and rear sound
levels is also important.
Keep in mind that if you are listening to
a stereo recording or broadcast, changing
the right/left balance will increase the vol-
ume of one group of sounds while de-
creasing the volume of another.
YOUR RADIO ANTENNA
To remove an antenna, carefully turn it
counterclockwise.
YOUR CASSETTE PLAYER
When you insert a cassette, the exposed
tape should face to the right.
NOTICE
Never try to disassemble or oil any
part of the cassette player. Do not
insert anything other than cassette
tapes into the slot.
YOUR COMPACT DISC PLAYER
(type 1 and type 2)
When you insert a disc, gently push it in
with the label side up. The player will play
from track 1 through to the end of the
disc. Then it will play from track 1 again.
NOTICE
Never try to disassemble or oil any
part of the compact disc player. Do
not insert anything other than com-
pact discs into the slot.

8 cm (3 in.) compact disc singles
Ty p e 1 —
Your compact disc player does not need
an adaptor to play compact disc singles.
Compact disc singles are about 8 cm (3
in.) in diameter−smaller than standard
discs.
After you eject a compact disc single, do
not insert a standard 12 cm (4.7 in.) disc
until “DISC” disappears from the display.
NOTICE
Do not use an adaptor for compact
disc singles —it could cause tracking
errors or interfere with the ejection of
compact discs.
Ty p e 2 —
The player is intended for use with 12 cm
(4.7 in.) discs only. YOUR COMPACT DISC PLAYER WITH
CHANGER (type 3)
When you insert a disc, push the “LOAD”
button and gently push the disc in with
the label side up. This compact disc play-
er can store up to six discs. The player
will play from track 1 through to the end
of the disc. Then it will play from track
1 of the next disc.
The player is intended for use with 12 cm
(4.7 in.) discs only.
NOTICE

Do not stack up two discs for in-
sertion, or it will cause damage to
the compact disc changer. Insert
only one compact disc into slot at
a ti me.
 Never try to disassemble or oil any
part of the compact disc player. Do
not insert anything other than com-
pact discs into the slot.

To allow proper operation of your
vehicle’s ventilation system, keep
the inlet grilles in front of the wind-
shield clear of snow, leaves, or oth-
er obstructions.
If you smell exhaust fumes in the
vehicle, open the side windows to
ensure plenty of fresh air enters the
vehicle. If you can smell exhaust
fumes even though there are no
other vehicles in the surrounding
area, have your vehicle checked by
your Toyota dealer. Continued in-
halation of exhaust fumes can lead
to death by gas poisoning.
Toyota does not recommend occu-
pying the rear cargo area when it
is fitted with a slidein camper,
camper shell or other type cover
while the engine is running. This
caution applies to both driving and
stopped or parked situations with
the engine running. Particular care
should be taken to prevent exhaust
gases from entering camper bodies,
trailers or other enclosures on or
around your vehicle. If exhaust
fumes are detected, open all win-
dows and thoroughly ventilate the
area.FUNCTIONS OF ENGINE OIL
Engine oil has the primary functions of
lubricating and cooling the inside of the
engine, and plays a major role in main-
taining the engine in proper working order.
ENGINE OIL CONSUMPTION
It is normal that an engine should con-
sume some engine oil during normal
engine operation. The causes of oil
consumption in a normal engine are as
follows.
Oil is used to lubricate pistons, piston
rings and cylinders. A thin film of oil
is left on the cylinder wall when a pis-
ton moves downwards in the cylinder.
High negative pressure generated when
the vehicle is decelerating sucks some
of this oil into the combustion chamber.
This oil as well as some part of the oil
film left on the cylinder wall is burned
by the high temperature combustion
gases during the combustion process.
Oil is also used to lubricate the stems
of the intake valves. Some of this oil
is sucked into the combustion chamber
together with the intake air and is
burned along with the fuel. High tem-
perature exhaust gases also burn the
oil used to lubricate the exhaust valve
stems.

NOTICE
If driving through water, such as
when crossing shallow streams,
first check the depth of the water
and the bottom of the river bed for
firmness. Drive slowly and avoid
deep water.
 Take all necessary safety measures
to ensure that water damage to the
engine or other components does
not occur.
Water entering the engine air intake
will cause severe engine damage.
Water can wash the grease from
wheel bearings, causing rusting and
premature failure, and may also en-
ter the differentials, transmission
and transfer case, reducing the gear
oil’s lubricating qualities.
 Sand and mud that has accumulated
in brake drums and around brake
discs may affect braking efficiency
and may damage brake system com-
ponents.
Always perform a maintenance in-
spection after each day of offroad
driving that has taken you through
rough terrain, sand, mud, or water.
For scheduled maintenance in-
formation, refer to the “Scheduled
Maintenance Guide” or “Owner’s
Manual Supplement”.Make sure your coolant is properly pro-
tected against freezing.
Only use “Toyota Super Long Life Coolant”
or similar high quality ethylene glycol
based non −silicate, non −amine, non− nitrite,
and non− borate coolant with long −life
hybrid organic acid technology. (Coolant
with long −life hybrid organic acid
technology is a combination of low
phosphates and organic acids.)
See “Checking the engine coolant level” in
Section 7 −2 for details of coolant type
selection.
For the U.S.A.—“Toyota Super Long Life
Coolant” is a mixture of 50% coolant and
50% deionized water. This coolant pro-
vides protection down to about −35 C
( − 31 F).
For Canada—“Toyota Super Long Life
Coolant” is a mixture of 55% coolant and
45% deionized water. This coolant pro-
vides protection down to about −42 C
( − 44 F).
NOTICE
Do not use plain water alone.
Winter driving tips

If your engine coolant temperature
gauge indicates overheating, if you ex-
perience a loss of power, or if you hear
a loud knocking or pinging noise, the
engine has probably overheated. You
should follow this procedure...
1. Pull safely off the road, stop the ve- hicle and turn on your emergency
flashers. Put the transmission in “P”
(automatic) or neutral (manual) and ap-
ply 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.
CAUTION
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.
3. Visually check to see if the enginedrive belt (fan belt) is broken or loose.
Look for obvious coolant leaks from the
radiator, hoses, and under the vehicle.
However, note that water draining from
the air conditioning is normal if it has
been used.
CAUTION
When the engine is running, keep
hands and clothing away from the
moving fan and engine drive belts.
4. If the engine drive belt is broken or thecoolant 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 quickly
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.
For the coolant type, see “Coolant type
selection” in Section 7 −2.
CAUTION
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 under pressure.
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 s hould have it checked as
soon as possible at your Toyota dealer.
If your vehicle overheats

Power steering fluid level
Check the level through the reservoir. The
level should be in the “HOT” or “COLD”
range depending on the fluid temperature.
See Section 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
Section 2.)
INSIDE THE VEHICLE
Items listed below should be checked
regularly, e.g. while performing periodic
services, cleaning the vehicle, etc.

and warning buzzers function properly.
Steering wheel
Be alert for changes in steering condition,
such as hard steering or strange noise. Seats
Check that all seat controls such as seat
adjusters, seatback recliner, etc. operate
smoothly and that all latches lock securely
in any position. Check that the head re-
straints move up and down smoothly and
that the locks hold securely in any latched
position. For folding
−down seatback, check
that the latches lock securely.
Seat belts
Check that the seat belt system such as
buckles, retractors and anchors operate
properly and smoothly. Make sure the belt
webbing is not cut, frayed, worn or dam-
aged.
Accelerator pedal
Check the pedal for smooth operation and
uneven pedal effort or catching.
Clutch pedal
Check the pedal for smooth operation.
Brake pedal
Check the pedal for smooth operation and
that the pedal has the proper clearance.
Check the brake booster function.

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 reuse iridiumtipped spark
plugs by cleaning or regapping.
 Do not overfill automatic transmis-
sion fluid, or the transmission
could be damaged.
 Do not drive with the air cleaner
filter removed, or excessive engine
wear could result. Also backfiring
could cause a fire in the engine
compartment.
 Be careful not to scratch the glass
surface with the wiper frame.
 When closing the engine hood,
check to see that you have not for-
gotten any tools, rags, etc.Here is a list of parts and tools you will
