YOUR AUDIO ANTENNA
Your vehicle has an antenna printed on
the inside of the rear window.
Attaching the film (especially
conductive or metalic type) on the
rear window will noticeably reducethe sensitivity of the radio.
NOTICE
YOUR CASSETTE PLAYER
When you insert a cassette, the exposed
tape should be to the right.
Do not oil any part of the player anddo not insert anything other than
cassette tapes into the slot, or thetape player may be damaged.
NOTICE
YOUR COMPACT DISC PLAYER
Your compact disc player has an automat-
ic charger which stores up to 12 discs. To
insert discs in the automatic changer, see
CD (Compact Disc) Auto changerº. The
compact disc player will play from track 1
through to the end of the disc. Then it will
play from track 1 again.
Never try to disassemble or oil anypart of the compact disc player. Do
not insert anything except acompact disc into the slot.
NOTICE
The player is intended for use with 12 cm
(4.7 in) discs only.

Keep the trunk lid closed while
driving. An open or unsealed
trunk lid may cause exhaust
gases to be drawn into the ve-
hicle. If you must drive with the
trunk lid open to accommodate a
large object, close the windows,
open all the instrument panel
vents and have the heating or
cooling system deliver fresh air
into the vehicle by turning the fan
to high speed with the air intake
control button set at the outside
air mode.

To allow proper operation of your
vehicle's ventilation system, keep
the inlet grilles in front of the
windshield clear of snow, leaves,
or other obstructions.

If you smell exhaust fumes in the
vehicle, drive with the windows
open and the trunk lid closed.
Have the cause immediately lo-
cated and corrected. FUNCTIONS OF ENGINE OIL
Engine oil has the primary functions of lu-
bricating and cooling the inside of the en-
gine,
and plays a major role in maintaining
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 piston
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 com-
bustion 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 cham-
ber 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 high-speed 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 re-
peated 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 the fuel or moisture, making it
appear that the oil level has not changed.

Tire surface and wheel nuts
Check the tires carefully
for cuts, damage
or excessive wear. See Chapter 7-2 for
additional information. When checking
the tires, make sure no nuts are missing,
and check the nuts for looseness. T ighten
them if necessary.
Tire rotation
Rotate the tires every 12000 km (7500
miles). See Chapter 7-2 for additional in-
formation.
Fluid leaks
Check underneath for leaking fuel, oil, wa-
ter or other fluid after the vehicle has been
parked for a while. If you smell fuel fumes
or notice any leak, have the cause found
and corrected immediately.
Doors and engine hood
Check that all doors including trunk lid op-
erate smoothly and all latches lock se-
curely. M ake sure the engine hood secon-
dary latch secures the hood from opening
when the primary latch is released.
INSIDE THE VEHICLE
Items listed below should be checked
regularly, e.g. while performing peri-
odic services, cleaning the vehicle,
etc. Lights
Make sure the headlights, stop lights, tail
lights, turn signal lights, and other lights
are all working. Check headlight aim.
Service reminder indicators and
warn-
ing buzzers
Check that all service reminder indicators
and warning buzzers function properly.
Steering wheel
Check that it has the specified freeplay.
Be alert for changes in steering condition,
such as hard steering or strange noise.
Seats
Check that all front seat controls such as
seat adjusters, seatback recliner, etc. op-
erate smoothly and that all latches lock
securely in any position. Check that the
head restraints move up and down
smoothly and that the locks hold securely
in any latched position.
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. Brake pedal
Check
the pedal for smooth operation and
that the pedal has the proper clearance.
Check the brake booster function.
Brakes
At a safe place, check that the brakes do
not pull to one side when applied.
Parking brake
Check that the pedal has the proper travel
and that, on a safe incline, your vehicle is
held securely with only the parking brake
applied.
Automatic transmission Parkº mech-
anism
Check the lock release button of the se-
lector lever for proper and smooth opera-
tion. On a safe incline, check that your ve-
hicle is held securely with the selector
lever in ºPº position and all brakes re-
leased.
IN THE ENGINE COMPARTMENT
Items listed below should be checked
from time to time, e.g. each time when
refueling.
Washer fluid
Make sure there is sufficient fluid in the
tank. See Chapter 7-3 for additional infor-
mation.ProCarManuals.com

178Engine coolant level
Make sure the coolant level is between
the ºFULLº and ºLOWº lines on the see-
through
reservoir when the engine is cold.
See Chapter 7-2 for additional informa-
tion.
Battery electrolyte level
Make sure the electrolyte level of all bat-
tery cells is between upper and lower level
lines on the case. Add only distilled water
when replenishing. See Chapter 7-3 for
additional information.
Brake fluid level
Make sure the brake fluid level is correct.
See Chapter 7-2 for additional informa-
tion.
Engine oil level
Check the l evel on the dipstick with the en-
gine turned off and the vehicle parked on
a level spot. See Chapter 7-2 for addition-
al information.
Power steering fluid level
Check the level through the reservoir. The
level should be in the HOTº or COLDº
range depending on the fluid t emperature.
See Chapter 7-2 for additional informa-
tion. 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
Part 2.)
Be on the alert for changes in perfor-
mance, sounds, and visual tip-offs
that in-
dicate service is needed. Some important
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 monox-
ide leak. Drive with the windows open
and have the exhaust system checked
immediately.)

Flat-looking 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 or clutch pedal; pedal al-
most touches floor; vehicle pulls to one
side when braking

Engine coolant temperature continual-
ly higher than normal
If you notice any of these clues, take your
vehicle to your Toyota dealer as soon as
possible. It probably needs adjustment or
repair.
Do not continue driving with the
vehicle unchecked. It could result
in serious vehicle damage and
possibly personal injury. CAUTION
