1997 TOYOTA AVALON park assist

134The diluting ingredients evaporate out
when the vehicle is then driven at high
speeds, as on an expressway, making it
appear 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 be
checked every time you refuel the vehicle.
Failure to check the oil level
regularly could lead to serious
engine trouble due to insufficientoil.
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 stopsÐbut no
more!

Type A
Type BABSº warning light
This light comes on when the ignition key
is turned to the ONº position. After about
3 seconds, the light will go off.
If either of the following conditions occurs,
this indicates a malfunction somewhere in
the parts monitored by the warning light
system. Contact your Toyota dealer as
soon as possible to service the vehicle.


The light does not come on as de-
scribed above, or remains on.

The light comes on while driving.
Even if the anti-lock brake system should
fail, the brake system will still operate con-
ventionally. However, when the `ABS''
warning light is on (and the brake system
warning light is off), the anti-lock brake
system is not assisting brake perfor-
mance so that the wheels can lock-up
during sudden braking or braking on slip-
pery road surfaces. Have your vehicle
checked by your Toyota dealer as soon as
possible DRUM-IN-DISC TYPE PARKING
BRAKE SYSTEM
Your vehicle has a drum-in-disc type
parking brake system. This type brake
system needs bedding-down of
the brake
shoes periodically or whenever the park-
ing brake shoes and/or drums are re-
placed.
Have your Toyota dealer perform the bed-
ding-down.

142Before starting the engine, be sure to fol-
low the instructions in (a) Before crank-
ingº.
Normal starting procedure
The multiport fuel injection system/se-
quential multiport fuel injection system in
your engine automatically controls the
proper air-fuel mixture for starting. You
can start a cold or hot engine as follows:
1. With your foot off the accelerator ped-
al, crank the engine by turning the key
to STARTº. Release it when the en-
gine starts.
2. After the engine runs for about 10 sec- onds, you are ready to drive.
If the weather is below freezing, let the en-
gine warm up for a few minutes before
driving.
If the engine stalls...
Simply restart it, using the correct proce-
dure given in normal starting.
If the engine will not startÐ
See If your vehicle will not startº in Part 4. 
Do not crank for more than 30 sec-
onds at a time. This may overheat
the starter and wiring systems.
Do not race a cold engine.
If the engine becomes difficult tostart or stalls frequently, have theengine checked immediately.
NOTICE
Always slow down in gusty cross-
winds. This will allow you much better
control

Drive slowly onto curbs and, if pos-
sible, at a right angle. Avoid driving
onto high, sharp-edged objects and
other road hazards. Failure to do so
can lead to severe tire damage result-
ing in tire bursts.

When parking on a hill, turn the front
wheels until they touch the curb so that
the vehicle will not roll. Apply the park-
ing brake, and place the transmission
in Pº. If necessary, block the wheels.

Washing your vehicle or driving
through deep water may get the
brakes wet. To see whether they are
wet, check that there is no traffic near
you, and then press the pedal lightly. If
you do not feel a normal braking force,
the brakes are probably wet. To dry
them, drive the vehicle cautiously
while lightly pressing the brake pedal
with the parking brake depressed. If
they still do not work safely, pull to the
side of the road and call a T oyota deal-
er for assistance.

152If the engine will not start, your engine
may be flooded because of repeated
cranking.
If this happens, turn the key to STARTº
with the accelerator pedal held down.
Keep
the key and accelerator pedal so for
15 seconds and release them. Then try
starting the engine with your foot off the
accelerator pedal.
If the engine does not start after 15 sec-
onds of cranking, release the key, wait a
few minutes and try again.
If the engine still will not start, it needs ad-
justment or repair. Call a Toyota dealer or
qualified repair shop for assistance.
NOTICE
Do not crank for more than 30 seconds at a time. This may
overheat the starter and wiringsystems.
To avoid serious personal injury and
damage to your vehicle which might
result from battery explosion, acid
burns, electrical burns, or damaged
electronic components, these instruc-
tions must be followed precisely.
If you are unsure about how to follow this
procedure, we strongly recommend that
you seek the help of a competent me-
chanic or towing service.

Batteries contain sulfuric acid
which is poisonous and corro-
sive. Wear protective safety
glasses when jump starting, and
avoid spilling acid on your skin,
clothing, or vehicle.

If you should accidentally get acid
on yourself or in you eyes, remove
any contaminated clothing and
flush the affected area with water
immediately. Then get immediate
medical attention. If possible,
continue to apply water with a
sponge or cloth while en route to
the medical office. CAUTION
!


The gas normally produced by a
battery will explode if a flame or
spark is brought near. Use only
standardized jumper cables and
do not smoke or light a match
while jump starting.
NOTICE
The battery used for boosting must be 12 V. Do not jump start unless
you are sure that the booster batteryis correct.

If your engine coolant temperature
gauge indicates overheating, if you
experience a loss of power, or if you
hear a loud knocking or pinging noise,
the engine has probably overheated.
You should follow this procedure
0
1. Pull safely off the road, stop the ve- hicle and turn on your emergency
flashers. Put the transmission in Pº
(automatic) or neutral (manual) and
apply 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 and make sure the electric
cooling fan is operating. If it is not, turn
the ignition off.
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. CAUTION
!
3. Look for obvious coolant leaks from
the radiator, hoses, and under the ve-
hicle. However, note that water drain-
ing from the air conditioning is normal
if it has been used.
When the engine is running, keep
hands and clothing away from the
moving fan and engine drive belts. CAUTION
!
4. If the coolant is leaking, stop the en-
gine immediately. Call a Toyota dealer
for assistance.
5. If there are no obvious leaks, check the coolant reservoir. If it is dry, add
coolant to the reservoir while the en-
gine is running. Fill it about half full.
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. CAUTION
!
6. After the engine coolant temperature
has cooled to normal, again check the
coolant level in the reservoir. If
necessary, bring it up to half full again.
Serious coolant loss indicates a leak in
the system. You should have it
checked as soon as possible at your
Toyota dealer.

If towing is necessary, we recommend
you to have it done by your Toyota
dealer or a commercial tow truck ser-
vice.
If towing service is not available in an
emergency, your vehicle may be tem-
porarily towed by a cable or chain se-
cured to either emergency towing eye-
let under the vehicle. Use extreme
caution when towing vehicles.
A driver must be in the vehicle to steer it
and operate the brakes.
Towing in this manner may be done only
on hard-surfaced roads for a short dis-
tance and at low speeds. Also, the
wheels, axles, drive train, steering and
brakes must all be in good condition.
CAUTION!
Use extreme caution when towing
vehicles. Avoid sudden starts or
erratic driving maneuvers which
would
place excessive stress on the
emergency towing eyelet and
towing cable or chain. The eyelets
and towing cable or chain may
break and cause serious injury or
damage.
NOTICE
Use only a cable or chain specifically intended for use in
towing vehicles. Securely fasten the
cable or chain to the towing eyelets provided.
Before towing, release the parking brake
and put the transmission in Nº. The key
must be in ACCº (engine off) or ONº (en-
gine running).
CAUTION!
If the engine is not running, the
power assist for the brakes and
steering will not work so steering
and braking will be much harder
than usual.

High pressure water or steam is effec-
tive for cleaning the vehicle's under-
side and wheel housings. Pay particu-
lar attention to these areas as it is
difficult to see all the mud and dirt. It
will do more harm than good to simply
wet the mud and debris without remov-
ing them. The lower edge of doors,
rocker panels and frame members
have drain holes which should not be
allowed to clog with dirt as trapped wa-
ter in these areas can cause corrosion.

Wash the underside of the vehicle
thoroughly when winter is over.
See Washing and waxing your Toyotaº
for more tips.
Check the condition of your vehicle's
paint and trim. If you find any chips or
scratches in the paint, touch them up im-
mediately to prevent corrosion from start-
ing. If the chips or scratches have gone
through the bare metal, have a qualified
bodyshop make the repair. Check the interior of your vehicle.
Wa-
ter and dirt can accumulate under the floor
mats and could cause corrosion. Occa-
sionally check under the mats to make
sure the area is dry. Be particularly careful
when transporting chemicals, cleansers,
fertilizers, salt, etc; these should be trans-
ported in proper containers. If a spill or
leak should occur, immediately clean and
dry the area.
Use mud shields on your wheels. If you
drive on salted or gravel roads, mud
shields help protect your vehicle. Full-
size shields, which come as near to the
ground as possible, are the best. We rec-
ommend that the fittings and the area
where the shields are installed be treated
to resist corrosion. Your Toyota dealer will
be happy to assist in supplying and instal-
ling the shields if they are recommended
for your area.
Do not park your vehicle in a damp,
poorly ventilated garage. If you wash
your vehicle in the garage, or if you drive
it in covered with water or snow, your ga-
rage may be so damp it will cause corro-
sion. Even if your garage is heated, a wet
vehicle can corrode if the ventilation is
poor. Washing your Toyota by hand
Work in the shade and wait until the ve-
hicle body is not hot to the touch.
CAUTION
When cleaning under floor or chas-
sis, be careful not to injure your
hands.!
1. Rinse off loose dirt with a hose. Re- move any mud or road salt from the
underside of the vehicle or in the wheel
wells.
2. Wash with a mild car-wash soap, mixed according to the manufacturer's
instructions. Use a soft cotton mitt and
keep it wet by dipping it frequently into
the wash water. Do not rub hard-let
the soap and water remove the dirt.
Aluminum wheels: Use only a mild soap or
neutral detergent.
Plastic bumpers: Wash carefully. Do not
scrub with ab rasive cleaners. The bumper
faces are soft.
Road tar: Remove with turpentine or
cleaners that are marked safe for painted
surfaces.
