1996 TOYOTA COROLLA engine control

80

To help maintain maximum control
of your vehicle, do not use the
cruise control when driving in
heavy or varying traffic, or on slip-
pery (rainy, icy or snow-covered)
or winding roads.

Avoid vehicle speed increases
when driving downhill. If the ve-
hicle speed is too fast in relation to
the cruise control set speed, can-
cel the cruise control then down-
shift the transmission to use en-
gine braking to slow down.CAUTION
!
TURNING ON THE SYSTEM
To operate the cruise control, push the
CRUISE ON-OFFº switch. This turns the
system on. The indicator light in the instru-
ment panel shows that you can now set
the vehicle at a desired cruising speed.
Another push will turn the system com-
pletely off.
To avoid accidental cruise control
engagement, keep the CRUISE ON-
OFFº switch off when not using the
cruise control.CAUTION
!
SETTING AT A DESIRED SPEED
On vehicles with automatic transmission,
the transmission must be in Dº before
you set the cruise control speed.
Bring your vehicle to the desired speed,
press the SET/COASTº direction and re-
lease it. This sets the vehicle at that
speed. Now you may take your foot off the
accelerator pedal. If you need accelera-
tionÐfor example, when passingÐde-
press the accelerator pedal enough for
the vehicle to exceed the set speed.
When you release it, the vehicle will return
to the speed set prior to the acceleration.
For manual transmission:
While driving with the cruise control
on, do not shift to neutral without
depressing the clutch pedal, as this
may cause engine racing or overrev-
ing.CAUTION
!
CANCELLING THE PRESET SPEED
You can cancel the preset speed by:
a. Pulling the control lever in the CAN-
CELº direction and releasing it.
b. Depressing the brake pedal.
c. Depressing the clutch pedal (manual
transmission).If the vehicle speed falls below about 40
km/h (25 mph), the preset speed will auto-
matically cancel out.
If the vehicle speed drops 16 km/h (10
mph) below the preset speed, the preset
speed will also automatically cancel out.
If the preset speed automatically cancels
out other than for the above cases, have
your vehicle checked by your Toyota deal-
er at the earliest opportunity.
RESETTING AT A FASTER SPEED
Press the control lever upward in the
RES/ACCº direction and hold it. Release
the lever when the desired speed is at-
tained. While the lever is held upward, the
vehicle will gradually gain speed.
However, a faster way to reset is to accel-
erate the vehicle and then press the lever
downward in the SET/COASTº direction.
RESETTING AT A SLOWER SPEED
Push the control lever downward in the
SET/COASTº direction and hold it. Re-
lease the lever when the desired speed is
attained. While the lever is held down-
ward, the vehicle speed will gradually de-
crease.

RADIO
FM reception tips
Most of us are not aware that a vehicle is
not an ideal place to listen to a radio. Be-
cause it moves, reception conditions
change continuously. Buildings, terrain,
signal distance and noise from other ve-
hicles are all working against good recep-
tion. Some FM reception conditions may
appear to be problems even though they
are normal.
The following characteristics are normal
for a given reception area, and they do not
indicate any problem with the radio itself.
Fading and Drifting: On the average,
the broadcast range of FM stations is
limited to about 40 km (25 miles), ex-
cept for some high power stations.If a vehicle is moving away from the
desired station's transmitter, the signal
will tend to fade and/or drift. This phe-
nomenon is more noticeable with FM
than with AM, and is accompanied by
distortion.
Fading and drifting can be minimized
to a certain degree by fine tuning, or
you should tune in to a stronger signal.
Static and Fluttering: When the line-
of-sight path between a transmitter
and vehicle is blocked by large build-
ings or the like, static or fluttering may
occur because of the characteristic of
FM. In a similar effect, a fluttering
noise is sometimes heard when driv-
ing along a tree-lined road.
This static and fluttering can be re-
duced by adjusting the tone control for
greater bass response until the distur-
bance has passed.
Multipath: Because of the reflection
characteristics of FM, direct and re-
flected signals may reach the antenna
at the same time (a phenomenon
called multipath reception) and cancel
each other out. As a vehicle moves
through these electronic dead spots,
the listener may hear a momentary
flutter or lose reception.

The three-way catalytic converter is
an emission control device installed in
the exhaust system.
The purpose is to reduce pollutants in the
exhaust gas.
CAUTION!

Keep people and combustible ma-
terials away from the exhaust pipe
while the engine is running. The
exhaust gas is very hot.

Do not drive, idle or park your ve-
hicle over anything that might burn
easily such as grass, leaves, paper
or rags.
A large amount of unburned gases
flowing into the three-way catalytic
converter may cause it to overheat
and create a fire hazard. To prevent
this and other damage, observe the
following precautions:
Use only unleaded gasoline.
Do not drive with an extremely low
fuel level; running out of fuel
could cause the engine to misfire,
creating an excessive load on the
three-way catalytic converter.
Do not allow the engine to run at
idle speed for more than 20 min-
utes.
Avoid racing the engine.
Do not push-start or pull-start
your vehicle.
Do not turn off the ignition while
the vehicle is moving.
Keep your engine in good running
order. Malfunctions in the engine
electrical system, electronic igni-
tion system/distributor ignition
system or fuel system could cause
an extremely high three-way cata-
lytic converter temperature.
NOTICEIf the engine becomes difficult to
start or stalls frequently, take your
vehicle in for a check-up as soon
as possible. Remember, your Toyo-
ta dealer knows your vehicle and its
three-way catalytic converter sys-
tem best.
To ensure that the three-way cata-
lytic converter and the engine
emission control system operate
properly, your vehicle must re-
ceive the periodic inspections re-
quired by the Toyota Maintenance
Schedule. For scheduled mainte-
nance information, refer to the
separate Owner's Manual Sup-
plement/Maintenance Scheduleº.

CAUTION!

Avoid inhaling the engine exhaust.
It contains carbon monoxide,
which is a colorless and odorless
gas. It can cause unconsciousness
or even death.

Make sure the exhaust system has
no holes or loose connections.
The system should be checked
from time to time. If you hit some-
thing, or notice a change in the
sound of the exhaust, have the sys-
tem 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 particularly
dangerous situation.

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

Keep the trunk lid or back door
closed while driving. An open or
unsealed trunk lid or back door
may cause exhaust gases to be
drawn into the vehicle. If you must
drive with the trunk lid or back door
open to accommodate a large ob-
ject, 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 lever set at the
OUTSIDE AIR position.

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.

If you smell exhaust fumes in the ve-
hicle, drive with the windows open
and the trunk lid or back door
closed. Have the cause immediately
located 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 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.

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 (vehicles
with ABSº warning light)
The anti-lock brake system is designed to
prevent lock-up of the wheels during sud-
den braking or braking on slippery road
surfaces. This assists the driver in con-
trolling the vehicle under these circum-
stances.
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.When the anti-lock brake system function
is in action, you may feel the brake pedal
pulsating and hear a noise. In this situa-
tion, to let the anti-lock brake system
work for you, just hold the brake pedal
down more firmly. Do not pump the brake.
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 capability 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.

11 6 Before 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 engine
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 15 sec-
onds at a time. This may overheat
the starter and wiring systems.
Do not race a cold engine.
If the engine becomes difficult to
start or stalls frequently, have the
engine 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 (automatic) or in first or reverse
(manual). 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 pulled. If they
still do not work safely, pull to the side
of the road and call a Toyota dealer for
assistance.
CAUTION!

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

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

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 consult a tire dealer to de-
termine 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
longer stopping distance, and it
may pull to one side when the
brakes are applied. Also, the park-
ing 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 deal-
erÐhe 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.Use 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 as washer fluid be-
cause 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 (automatic) or into first or reverse
(manual) and block the rear wheels. Do
not use the parking brake, or snow or wa-
ter accumulated 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.
