1997 TOYOTA AVALON oil dipstick

(a) Brake System Warning Light
This light has the following functions:
Parking brake reminder
If this light is on, make sure the parking
brake is fully released. The light should go
off.
Low brake fluid level warning
If this light comes on and stays on while
you are driving, slowdown and pull off the
road. Then stop the vehicle carefully.
There may be a problem somewhere in
the brake system. Check the fluid level of
the see-through reservoir.
To make sure the parking brake has not
caused the warning light to come on,
check to see that the parking brake is fully
released.
If the brake fluid level is low...
At a safe place, test your brakes by start-
ing and stopping.


If you judge that the brakes still work
adequately, drive cautiously to your
nearest dealer or shop for repairs.

If the brakes are not working, have the
vehicle towed in for repairs. (For tow-
ing information, see Part 4.)
It is dangerous to continue driving
normally when the brake fluid level
is low. CAUTION
!
If the brake fluid level is correct...
Have the warning system checked by
your Toyota dealer.
(b) Seat Belt Reminder Light and
Buzzer
Once the ignition key is turned to ONº or
STARTº, the reminder light and buzzer
come on if the driver's seat belt is not fas-
tened. Unless the driver fastens the belt,
the light stays on and the buzzer stops af-
ter about 4 to 8 seconds.
(c) Discharge Warning Light
This light warns that the battery is being
discharged.
If it comes on while you are driving, there
is a problem somewhere in the charging
system. The engine ignition will continue to oper-
ate, however, until the battery is dis-
charged. Turn off the air conditioning,
blower, ra
dio, etc., and drive directly to the
nearest Toyota dealer or repair shop.
NOTICE
Do not continue driving if the engine drive belt is broken or loose.
(d) Low Oil Level Warning Light
This light warns that the engine oil pres-
sure is too low.
If it flickers or stays on while you are driv-
ing, pull off the road to a safe place and
stop the engine immediately. Call a Toyo-
ta dealer or qualified repair shop for assis-
tance.
The light may occasionally flicker when
the engine is idling or it may come on brief-
ly after a hard stop. There is no cause for
concern if it then goes out when the en-
gine is accelerated slightly.
The light may come on when the oil level
is extremely low. It is not designed to indi-
cate low oil level, and the oil level must be
checked using the level dipstick.

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.

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

Aluminum wheel precautions
With the engine at operating tempera-
ture and turned off, check the oil level
on the dipstick.
1. To get a true reading, the vehicle
should be on a level spot. After turning
off the engine, wait a few minutes for
the oil to drain back into the bottom of
the engine.
2. Pull out the dipstick, and wipe it clean with a rag.
3. Reinsert the dipstick' push it in as far
as it will go, or the reading will not be
correct.
4. Pull the dipstick out and look at the oil level on the end.
CAUTION
Be careful not to touch the hot
exhaust manifold.!
If the oil level is below or only slightly
above the low level, add engine oil of
the same type as already in the engine.
Remove the oil filler cap and add engine
oil in small quantities at a time, checking
the dipstick.
The approximate quantity of oil needed to
fill between the low level and the full level
on the dipstick is indicated below for refer-
ence.
When the level reaches within the correct
range, install the filler cap hand-tight.
Oil quantity, L (qt., Imp. qt.): 1.5 (1.6, 1.3)

Avoid overfilling, or the engine could be damaged.
Check the oil level on the dipstick
once again after adding the oil.
