1997 TOYOTA AVALON check engine

132
Do not allow the engine to run atidle speed for more than 20 min-
utes.
Avoid racing the engine.
Do not push-start or pull-startyour vehicle.
Do not turn off the ignition whilethe vehicle is moving.
Keep your engine in good running
order. Malfunctions in the engine electrical system, electronic igni-
tion system/distributor ignitionsystem or fuel system engine ex-haust cautions could cause an ex-
tremely high three-way catalytic converter temperature.
If the engine becomes difficult tostart or stalls frequently, take your
vehicle in for a check-up as soon as possible. Remember, your To-
yota dealer knows your vehicleand its three-way catalytic con-verter system best.
To ensure that the three-way cata-lytic converter and the engine
emission control system operateproperly, your vehicle must re-ceive the periodic inspections re-
quired by the T oyota Maintenance
Schedule. For scheduled mainte- nance information, refer to the
separate Owner's Manual Sup-plement/Maintenance Scheduleº.CAUTION!

Avoid inhaling the engine ex-
haust. It contains carbon monox-
ide, which is a colorless and odor-
less gas. It can cause uncon-
sciousness or even death.

Make sure the exhaust system
has no holes or loose connec-
tions. The system should be
checked from time to time. If you
hit something, or notice a change
in the sound of the exhaust, have
the system checked immediately.

Do not run the engine in a garage
or enclosed area except for the
time needed to drive the vehicle in
or out. The exhaust gases cannot
escape, making this a paticularly
dangerous situation.

Do not remain for a long time in a
parked vehicle with the engine
running. If it is unavoidable, how-
ever, do so only in an unconfined
area and adjust the heating or
cooling system to force outside
air into the vehicle.

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!

CAUTION!

Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your vacuum re-
serve.

Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hardÐmuch harder than nor-
mal. And your braking distance will
be longer.
ANTI-LOCK BRAKE SYSTEM
(with ABSº warning light)
The anti-lock brake system is designed to
automatically prevent lock-up of the
wheels during sudden braking or braking
on slippery road surfaces. This assists in
providing directional stability and steering
performance of the vehicle under these
circumstances.
The anti-lock brake system becomes op-
erative after the vehicle has accelerated
to a speed in excess of approximately 10
km/h (6 mph). It stops operating when the
vehicle decelerates to a speed below
approximately 5 km/h (3 mph). You may hear a sound in the engine
compartment for a
few seconds when the
engine is started or just after the vehicle
is started. This means that the anti-lock
brake system is in the self check mode,
and does not indicate a malfunction.
Effective way to press the ABSº brake
pedal: When the an ti-lock brake system
function is in action, you may feel the
brake pedal pulsating and hear a noise.
In this situation, to let the anti-lock brake
system work for you, just hold the brake
pedal down more firmly. Do not pump
the brake. This will result in reduced
braking performance.
The brake pedal pulsation caused by the
anti-lock brake system may indicate haz-
ardous road surface conditions. Although
the anti-lock brake system assists in pro-
viding vehicle control, it is still important to
drive with all due care, because the anti-
lock brake system cannot overcome the
laws of physics that act on your vehicle:

Braking c apability is dependent on tire
friction with the road surface.

Even though the anti-lock brake sys-
tem is operating, a driver cannot main-
tain full control on certain slippery road
surfaces, when cornering at high
speeds, or in violent maneuvers.

Avoid high speeds on wet roads. The
anti-lock brake system cannot elimi-
nate the risk of hydroplaning and loss
of tire friction.
Always maintain a safe distance from the
vehicle in front of you. Compared with ve-
hicles not fitted with an anti-lock brake
system, your vehicle may require a longer
stopping distance in the following cases:

Driving on rough, gravel or snow-cov-
ered roads.

Driving with tire chains installed.

Driving on roads where the road sur-
face is pitted or has other differences
in surface height.

How to save fuel and make your
vehicle last longer, too
1. Check the area around the vehicle be-
fore entering it.
2. Adjust seat position, seatback angle, head restraint height and steering
wheel angle.
3. Adjust inside and outside rear view mirrors.
4. Lock all doors.
5. Fasten seat belts. 1. Apply the parking brake firmly.
2. Turn off unnecessary lights and acces-
sories.
3. Put the selector lever in Pº. If you need to restart the engine while the ve-
hicle is moving, put the selector lever
in Nº. A starter safety device will pre-
vent the starter from operating if the
selector lever is in any drive position.
4. Depress the brake pedal and hold it to the floor until driving off.

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.

CAUTION

Before driving off, make sure that
the parking brake if fully released
and the parking brake reminder
light is off.

Do not leave your vehicle unat-
tended while the engine is running.

Do not rest your foot on the brake
pedal while driving. It can cause
dangerous overheating, needless
wear, and poor fuel economy.

To drive down a long or steep hill,
reduce your speed and downshift.
Remember, if you ride the brakes
excessively, they may overheat and
not work properly.

Be careful when accelerating, up-
shifting, downshifting or braking
on a slippery surface. Sudden ac-
celeration or engine braking, could
cause the vehicle to spin or skid.!
Do not drive in excess of the speed
limit. Even if the legal speed limit
permits it, do not drive over 140
km/h (85 mph) unless your vehicle
has high-speed capability tires.
Driving over 140 km/h (85 mph) may
result in tire failure, loss of control
and possible injury. Be sure to con-
sult a tire dealer to determine
whether the tires on your vehicle
are high-speed capability tires or
not before driving at such speeds.

Do not continue normal driving
when the brakes are wet. If they are
wet, your vehicle will require a lon-
ger stopping distance, and it may
pull to one side when the brakes are
applied. Also, the parking brake
will not hold the vehicle securely. Make sure you have ethylene-glycol
antifreeze in the radiator.
Do not use alcohol type antifreeze.
NOTICE
Check the condition of the battery and
cables.
Cold temperatures reduce the capacity of
any battery, so it must be in top shape to
provide enough power for winter starting.
Chapter 7-3 tells you how to visually in-
spect the battery. Your Toyota dealer and
most service stations will be pleased to
check the level of charge.
Make sure the engine oil viscosity is
suitable for the cold weather.
See Chapter 7-2 for recommended vis-
cosity.
Leaving a heavy summer oil in your
vehicle during winter months may cause
harder starting. If you are not sure about
which oil to use, call your Toyota dealer-
he will be pleased to help.
Keep the door locks from freezing.
Squirt lock de-icer or glycerine into the
locks to keep them from freezing. To open
a frozen lock, try heating the key before in-
serting it.
Winter driving tips
ProCarManuals.com

144Use a washer fluid containing an anti-
freeze solution.
This product is available at your Toyota
dealer and most auto parts stores. Follow
the manufacturer's directions for how
much to mix with water.
Do not use engine antifreeze or any
other substitute because it may
damage your vehicle's paint.
NOTICE
Do not use your parking brake when
there is a possibility it could freeze.
When parking, put the transmission into
Pº and block the rear wheels. Do not use
the parking brake, or snow or water accu-
mulated in and around the parking brake
mechanism may freeze, making it hard to
release.
Keep ice and snow from accumulating
under the fenders.
Ice and snow built up under your fenders
can make steering difficult. During bad
winter driving, stop and check under the
fenders occasionally. Depending on where you are driving,
we recommend you carry some emer-
gency equipment.
Some of the things you might put in the ve-
hicle are tire chains, window scraper, bag
of sand or salt, flares, small shovel, jump-
er cables, etc.
Your vehicle is designed primarily as a
passenger-carrying vehicle. Towing a
trailer will have an adverse effect on han-
dling, performance, braking, durability
and driving economy (fuel consumption,
etc.). Your safety and satisfaction
depend
on the proper use of correct equipment
and cautious driving habits. For your safe-
ty and the safety of others, you must not
overload your vehicle or trailer. Toyota
warranties do not apply to damage or mal-
function caused by towing a tailer for com-
merical purposes. Ask your local Toyota
dealer for further details before towing.
WEIGHT LIMITS
Before towing, make sure the total trailer
weight, gross vehicle weight, gross axle
weight and trailer tongue load are all with-
in the limits.
The total trailer weight and tongue load
can be measured with platform scales
found at a highway weighing station,
building supply company, trucking com-
pany, junk yard, etc.

BREAK-IN SCHEDULE


Toyota recommends that you do not
tow a trailer with a new vehicle or a ve-
hicle with any new power train compo-
nent (engine, transmission, differen-
tial, wheel bearing, etc.) for the first
800 km (500 miles) of driving.
MAINTENANCE

If you tow a trailer, your vehicle will re-
quire more frequent maintenance due
to the additional load. For this informa-
tion, please refer to the scheduled
maintenance information in the Own-
er 's Manual Supplement/Maintenance
Scheduleº.

Retighten all fixing bolts of the towing
ball and bracket after approximately
1000 km (600 miles) of trailer driving.
PRE-T OWING SAFETY CHECK

Check that your vehicle remains level
when a loaded or unloaded trailer is
hitched. Do not drive if the vehicle has
an abnormal nose-up or nose-down
condition, and check for improper
tongue load, overload, worn suspen-
sion or other possible causes.

Make sure the trailer cargo is securely
loaded so that it cannot shift.

Check that your rear view mirrors con-
form to any applicable federal, state/
provincial or local regulation. If not,
install the rear view mirrors required
for towing purpose.
TRAILER TOWING TIPS
When towing a trailer, your vehicle will
handle differently than when not tow-
ing. The three main causes of vehicle
trailer accidents are driver error, ex-
cessive speed and improper trailer
loading. Keep these in mind when tow-
ing:

Before starting out, check operation of
the lights and all vehicle-trailer con-
nections. After driving a short dis-
tance, stop and recheck the lights and
connections. Before actually towing a
trailer, practice turning, stopping and
backing with a trailer in an area away
from traffic until you learn the feel.

Backing w ith a trailer is difficult and re-
quires practice. Grip the bottom of the
steering wheel and move your hand to
the left to move the trailer to the left.
Move your hand to the right to move
the trailer to the right. (This procedure
is generally opposite to that when
backing without a trailer). Also, just
turn the steering wheel a little at a time,
avoiding sharp or prolonged turning.
Have someone guide you when back-
ing to reduce the risk of an accident.

Because stopping distance may be in-
creased, vehicle-to-vehicle distance
should be increased when towing a
trailer. For each 16 km/h (10 mph) of
speed, allow at least one vehicle and
trailer length between you and the ve-
hicle ahead. Avoid sudden braking as
you may skid, resulting in jackknifing
and loss of control. This is especially
true on wet or slippery surfaces.

Avoid jerky starts or sudden accelera-
