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
Mast type antenna—
To remove: Turn it counterclockwise care-
fully.
To install: Turn it clockwise securely.
NOTICE

Mast type antenna:
To prevent damage to the antenna,
make sure it is removed before
driving your Toyota through an au-
tomatic car wash.
 Onglass antenna (builtin on the
rear window glass):
Attaching the film (especially con-
ductive or metallic type) on the rear
glass will noticeably reduce the
sensitivity of the radio.
YOUR CASSETTE PLAYER
When you insert a cassette, the exposed
tape should face to the right.
NOTICE
Do not oil any part of the player and
do not insert anything other than cas-
sette tapes into the slot, or the tape
player may be damaged.
YOUR COMPACT DISC PLAYER (type 1)
When you insert a disc, gently push it in
with the label side up. (The player will
automatically eject a disc if the label side
is down.) The compact disc player will
play from track 1 through 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.
The player is intended for use with 12 cm
(4.7 in.) discs only.
YOUR COMPACT DISC CHANGER (type
2)
When you insert a disc, push the “LOAD”
button, wait for the load/eject status light
to turn green, then gently push the disc
in with the label side up. (The player will
automatically eject a disc if the label side
is down.) The compact disc changer will
play from track 1 through the end of the
disc. Then it will play from track 1 of the
next disc.
The changer 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 except a com-
pact disc 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.
Keep the back door closed while
driving. An open or unsealed back
door may cause exhaust gases to
be drawn into the vehicle.
If you smell exhaust fumes in the
vehicle, drive with the windows
open and the back door closed.
Have the cause immediately located
and corrected.
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.
The amount of engine oil consumed de-
pends on the viscosity of the oil, the
quality of the oil and the conditions the
vehicle is driven under.
More oil is consumed by highspeed driv-
ing and frequent acceleration and decel-
eration.
A new engine consumes more oil, since
its pistons, piston rings and cylinder walls
have not become conditioned.
When judging the amount of oil con-
sumption, note that the oil may become
diluted and make it difficult to judge
the true level accurately.
As an example, if a vehicle is used for
repeated short trips, and consumes a nor-
mal amount of oil, the dipstick may not
show any drop in the oil level at all, even
after 1000 km (600 miles) or more. This
is because the oil is gradually becoming
diluted with fuel or moisture, making it
appear that the oil level has not changed.

consumption

Battery electrolyte level
Your Toyota has a maintenance free bat-
tery. You do not have to add distilled wa-
ter. For longer life of the battery, however,
see page 276 for additional information.
Brake fluid level
Make sure the brake fluid level is correct.
See page 264 in Section 72 for addition-
al information.
Engine oil level
Check the level on the dipstick with the
engine turned off and the vehicle parked
on a level spot. See page 260 in Section
72 for additional information.
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 page 265 in Section 72 for addition-
al 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” on
page 189 in Section 2.) Be on the alert for changes in perfor-
mance, sounds, and visual tipoffs that
indicate service is needed. Some impor-
tant 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 monoxide
leak. Drive with the windows open and
have the exhaust system checked im-
mediately.)
Flatlooking 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 suspension
movement
Loss of brake effectiveness; spongy
feeling brake pedal; pedal almost
touches floor; vehicle pulls to one side
when braking
Engine coolant temperature continually
higher than normalIf you notice any of these clues, take your
vehicle to your Toyota dealer as soon as
possible. It probably needs adjustment or
repair.
CAUTION
Do not continue driving with the ve-
hicle unchecked. It could result in se-
rious vehicle damage and possibly
personal injury.

NOTICE
Be careful not to spill the engine
oil on the vehicle components.
 Avoid overfilling, or the engine
could be damaged.
 Check the oil level on the dipstick
once again after adding the oil.
ENGINE OIL SELECTION
“Toyota Genuine Motor Oil” is f illed in
your Toyota vehicle. Use Toyota approved
“Toyota Genuine Motor Oil” or equivalent
to satisfy the following grade and
viscosity.
Oil grade: API grade SL “EnergyConserving” or
ILSAC multigrade engine oil
Recommended viscosity: SAE 5W30
Outside temperature
SAE 5W30 is the best choice for good
fuel economy and good starting in cold
weather.
If SAE 5W30 is not available, SAE
10W30 may be used. However, it
should be replaced with SAE 5W30 at
the next oil change.

as necessary.
Generally, it is necessary to change
automatic transmission fluid only if your
vehicle is driven under one of the Special
Operating Conditions listed in your
“Scheduled Maintenance Guide” or

shift quality, locking up of your trans-
mission accompanied by vibration, and
ultimately damage the automatic trans-
mission of your vehicle.
Please contact your Toyota dealer for fur-
ther details.
