CAUTION!

Avoid inhaling the engine exhaust.
It contains carbon monoxide,
which is a colorless and odorless
gas. It can cause unconscious-
ness 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
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 particularly
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.

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 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 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
other obstructions.

If you smell exhaust fumes in the
vehicle, drive with the windows
open and the trunk lid or back
door closed. Have the cause im-
mediately 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.

CAUTION!

Before driving off, make sure that
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 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 se-
curely.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 dealerÐ
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.

152If 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. 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 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 engine is running.
Fill it about half full.
Do not attempt to remove the radia-
tor cap when the engine and radia-
tor are hot. Serious injury could re-
sult 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.

Check the level 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 temperature.
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.)ProCarManuals.com

182If 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.)

Right after driving, the engine
compartmentÐthe engine, radia-
tor, exhaust manifold 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 flam-
mable.

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.
Always use automotive jack
stands or other solid supports.CAUTION
!
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
fans will automatically start to run
if the engine coolant temperature
is high and/or 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 fil-
ter in household trash, in sewers
or onto the ground. Call your deal-
er or a service station for informa-
tion concerning recycling or dis-
posal.
