air condition TOYOTA COROLLA 1996 User Guide

109 The amount of engine oil consumed
depends 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 be-
come 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 fuel or moisture, making it ap-
pear that the oil level has not changed.
The 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 at 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.
NOTICE
Failure to check the oil level
regularly could lead to serious
engine trouble due to insufficient
oil.
For detailed information on oil level check,
see Checking the engine oil levelº in
Chapter 7-2.TANDEM MASTER CYLINDER BRAKE
SYSTEM
The tandem master cylinder brake system
is a hydraulic system with two separate
sub-systems. If either sub-system should
fail, the other will still work. However, the
pedal will be harder to press, and your stop-
ping 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.

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.

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-
tion. If your vehicle has manual trans-
mission, prevent excessive clutch slip-
page by keeping engine rpm low and
not racing the engine. Always start out
in first gear.

Avoid jerky steering and sharp turns.
The trailer could hit your vehicle in a
tight turn. Slow down before making a
turn to avoid the necessity of sudden
braking.

Remember that when making a turn,
the trailer wheels will be closer than
the vehicle wheels to the inside of the
turn. Therefore, compensate for this
by making a larger than normal turning
radius with your vehicle.
Crosswinds and rough roads will ad-
versely affect handling of your vehicle
and trailer, causing sway. Pay atten-
tion to the rear from time to time to pre-
pare yourself for being passed by large
trucks or buses, which may cause your
vehicle and trailer to sway. If swaying
happens, firmly grip the steering wheel
and reduce speed immediately but
gradually. Never increase speed.
Steer straight ahead. If you make no
extreme correction with the steering or
brakes, the vehicle and trailer will sta-
bilize.

Be careful when passing other ve-
hicles. Passing requires considerable
distance. After passing a vehicle, do
not forget the length of your trailer and
be sure you have plenty of room be-
fore changing lanes.

In order to maintain engine braking effi-
ciency, do not use fifth gear (manual
transmission or overdrive (automatic
transmission).
Because of the added load of the trail-
er, your vehicle's engine may overheat
on hot days (at temperatures over
305C [855F]) when going up a long or
steep grade with a trailer. If the engine
coolant temperatue gauge indicates
overheating, immediately turn off the
air conditioning (if in use), pull off the
road and stop in a safe spot. Refer to
If your vehicle overheatsº in Part 4 of
this manual.

Always place wheel blocks under both
the vehicle and trailer wheels when
parking. Apply the parking brake firm-
ly. Put the transmission in Pº (auto-
matic) or in first or reverse (manual).
Avoid parking on a slope with a trailer,
but if it cannot be avoided, do so only
after performing the following:
1. Apply the brakes and hold.
2. Have someone place wheel blocks un-
der both the vehicle and trailer wheels.
3. When the wheel blocks are in place,
release your brakes slowly until the blocks
absorb the load.
4. Apply the parking brake firmly.
5. Shift into first or reverse (manual) or
Pº (automatic) and turn off the engine.ProCarManuals.com

123
Keep the bottom of your vehicle
free from mud, etc. This not only
lessens weight but also helps prevent
corrosion.

Keep your vehicle tuned-up and in
top shape. A dirty air cleaner, carbu-
retor out of adjustment, improper valve
clearance, dirty plugs, dirty oil and
grease, brakes not adjusted, etc. all
lower engine performance and con-
tribute to poor fuel economy. For lon-
ger life of all parts and lower operating
costs, keep all maintenance work on
schedule, and if you often drive under
severe conditions, see that your ve-
hicle receives more frequent mainte-
nance. (For scheduled maintenance
information, please refer to the sepa-
rate Owner's Manual Supplement/
Maintenance Scheduleº).
CAUTION!
Never turn off the engine to coast
down hills. Your power steering and
brake booster will not function with-
out the engine running. Also, the
emission control system operates
properly only when the engine is
running.

128If your engine stalls while driving0
1. Reduce your speed gradually, keeping
a straight line. Move cautiously off the
road to a safe place.
2. Turn on your emergency flashers.
3. Try starting the engine again.
If the engine will not start, see If your ve-
hicle will not startº.
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.CAUTION
!
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 procedure0
1. Pull safely off the road, stop the vehicle
and turn on your emergency flashers. Put
the transmission in Pº (automatic) or neu-
tral (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 oper-
ating. 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. Visually check to see if the engine drive
belt (water pump belt) is broken or loose.
Look for obvious coolant leaks from the
radiator, hoses, and under the vehicle.
However, note that water draining 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 engine drive belt is broken or the
coolant is leaking, stop the engine imme-
diately. Call a Toyota dealer for assis-
tance.
5. If the engine drive belt is O.K. and
there are no obvious leaks, check the
coolant reservoir. If it is dry, add coolant to
the reservoir while the engine is running.
Fill it about half full.
Do not attempt to remove the radia-
tor 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 cool-
ant loss indicates a leak in the system.
You should have it checked as soon as
possible at your Toyota dealer.

Protecting your Toyota from
corrosion

Washing and waxing your
Toyota

Cleaning the interior
Toyota, through its diligent research, de-
sign and use of the most advanced
technology available, has done its part to
help prevent corrosion and has provided
you with the finest quality vehicle
construction. Now, it is up to you. Proper
care of your Toyota can help ensure long-
term corrosion prevention.
The most common causes of corro-
sion to your vehicle are:

The accumulation of road salt, dirt and
moisture in hard-to-reach areas un-
der the vehicle.

Chipping of paint, or undercoating
caused by minor accidents or by
stones and gravel.
Care is especially important if you live
in particular areas or operate your ve-
hicle under certain environmental
conditions:

Road salt or dust control chemicals will
accelerate corrosion, as will the pres-
ence of salt in the air near the sea-
coast or in areas of industrial pollution.

High humidity accelerates corrosion
especially when temperatures range
just above the freezing point.

Wetness or dampness to certain parts
of your vehicle for an extended period
of time, may cause corrosion even
though other parts of the vehicle may
be dry.
High temperatures will cause corro-
sion to those components of the ve-
hicle which are prevented from quick-
drying due to lack of proper ventilation.
The above signifies the necessity to keep
your vehicle, particularly the underside,
as clean as possible and to repair any
damage to paint or protective coatings as
soon as possible.
To help prevent corrosion on your To-
yota, follow these guidelines:
Wash your vehicle frequently. It is, of
course, necessary to keep your vehicle
clean by regular washing, but to prevent
corrosion, the following points should be
observed:

If you drive on salted roads in the win-
ter or if you live near the ocean, you
should hose off the undercarriage at
least once a month to minimize corro-
sion.

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.
ProCarManuals.com

140
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
body shop 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, fertiliz-
ers, salt, etc; these should be transported
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.
1. Rinse off loose dirt with a hose. Re-
move any mud or road salt from the un-
derside of the vehicle or in the wheel
wells.
2. Wash with a mild car-wash soap,
mixed according to the manufacturer's in-
structions. Use a soft cotton mitt and keep
it wet by dipping it frequently into the wash
water. Do not rub hardÐlet 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 abrasive cleaners. The bumper
faces are soft.
Road tar: Remove with turpentine or
cleaners that are marked safe for painted
surfaces.
Do not use gasoline or strong
solvents, which may be toxic or
cause damage.
NOTICE
3.Rinse thoroughlyÐdried soap can cause
streaking. In hot weather you may need to
rinse each section right after you wash it.

142Begin by vacuuming thoroughly to re-
move as much dirt as possible. Several
types of foam cleaners are available;
some are in aerosol cans and others are
powders or liquids which you mix with wa-
ter to produce a foam. To shampoo the
carpets, use a sponge or brush to apply
the foam. Rub in overlapping circles.
Do not apply waterÐthe best results are
obtained by keeping the carpet as dry as
possible. Read the shampoo instructions
and follow them closely.
Seat belts
The seat belts may be cleaned with
mild soap and water or with lukewarm
water.
Use a cloth or sponge. As you are clean-
ing, check the belts for excessive wear,
fraying, or cuts.
Do not use dye or bleach on the
beltsÐit may weaken them.
NOTICE
Built-in child restraint
The built-in child restraint may be
cleaned with mild soap and lukewarm
water.
Do not use dye or bleach on the
beltsÐit may weaken them.
NOTICE
The built-in child restraint pad is at-
tached to the child restraint cushion
and seatback with fastener tapes. You
can remove the pad, machine wash it
in cold water and tumble dry it on a low
heat setting.
Never bleach or iron the pad, and do
not dry clean it.
NOTICE
Windows
The windows may be cleaned with any
household window cleaner.
When cleaning the inside of the
windows, be careful not to scratch or
damage the heater wires on the rear
window.
NOTICE
Air conditioning control panel, car au-
dio, instrument panel, console panel,
and switches
Use a soft damp cloth for cleaning.
Soak a clean soft cloth in water or luke-
warm water then lightly wipe off any dirt.

Do not use organic substances
(solvents, kerosene, alcohol, gas-
oline, etc.) or alkaline or acidic
solutions. These chemicals can
cause discoloring, staining or
peeling of the surface.
NOTICE
If you use cleaners or polishing
agents, make sure their ingredi-
ents do not include the sub-
stances mentioned above.
If you use a liquid car freshener, do
not spill the liquid onto the ve-
hicle's interior surfaces. It may
contain the ingredients mentioned
above. Immediately clean any spill
using the method mentioned
above.

146Be 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 normalIf 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 ve-
hicle unchecked. It could result in
serious vehicle damage and possi-
bly personal injury.CAUTION
! Does your vehicle need
repairing?

151 If you perform maintenance by your-
self, be sure to follow the correct pro-
cedure given in this part.
You should be aware that improper or in-
complete servicing may result in operat-
ing problems.
Performing do-it-yourself maintenance
during the warranty period may affect
your warranty coverage. Read the sepa-
rate Toyota Warranty statement for details
and suggestions.
This part gives instructions only for those
items that are relatively easy for an owner
to perform. As explained in Part 6, there
are still a number of items that must be
done by a qualified technician with special
tools.
For information on tools and parts for do-
it-yourself maintenance, see Parts and
toolsº.
Utmost care should be taken when work-
ing on your vehicle to prevent accidental
injury. Here are a few precautions that you
should be especially careful to observe:

When the engine is running, keep
hands, clothing, and tools away
from the moving fan and engine
drive belts. (Removing rings,
watches, and ties is advisable.)CAUTION
!

Right after driving, the engine
compartmentÐthe engine, radia-
tor, exhaust manifold, power
steering fluid reservoir and spark
plug boots, etc.Ðwill be hot. So
be careful not to touch them. Oil,
fluids and spark plugs may also be
hot.

If the engine is hot, do not remove
the radiator cap or loosen the drain
plugs to prevent burning yourself.

Do not smoke, cause sparks or al-
low open flames around fuel or the
battery. Their fumes are flamable.

Be extremely cautious when work-
ing on the battery. It contains poi-
sonous and corrosive sulfuric
acid.

Do not get under your vehicle with
just the body jack supporting it. Al-
ways use automotive jack stands
or other solid supports.

Be sure that the ignition is off if you
work near the electric cooling fans
or radiator grille. With the ignition
on, the electric cooling fan may au-
tomatically start to run if the air
conditioning is on.
Use eye protection whenever you
work on or under your vehicle
where you may be exposed to fly-
ing or falling material, fluid spray,
etc.

Used engine oil contains poten-
tially harmful contaminants which
may cause skin disorders such as
inflammation or skin cancer, so
care should be taken to avoid pro-
longed and repeated contact with
it. To remove used engine oil from
your skin, wash thoroughly with
soap and water.

Do not leave used oil within the
reach of children.

Dispose of used oil and filter only
in a safe and acceptable manner.
Do not dispose of used oil and filter
in household trash, in sewers or
onto the ground. Call your dealer
or a service station for information
concerning recycling or disposal.
