FUNCTIONS OF ENGINE OIL
Engine oil has the primary functions of lubri-
cating and cooling the inside of the engine,
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 cham-
ber 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. 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 driving
and frequent acceleration and deceleration.
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 normal
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 be-
cause the oil is gradually becoming diluted
with the fuel or moisture, making it appear
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 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.
NOTICE
Failure to check the oil level regularly could lead to serious
engine trouble due to insufficientoil.
For detailed information on the oil level
check, see Checking the engine oil levelº
in Chapter 7-2.

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, down shifting 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.

NOTICE
Remember that battery and igni-tion cable carry high currents or
voltages. Be careful of accidental-ly causing a short circuit.
Add only demineralized or dis-tilled water to fill the radiator. Andif you spill some of the coolant, besure to wash it off with water to
prevent it from damaging theparts or paint.
Do not allow dirt or anything elseto fall through the spark plugholes.
Do not pry the outer electrode of aspark plug against the center elec-
trode.
Use only spark plugs of the speci- fied type. Using other types willcause engine damage, loss of per-
formance or radio noise.
Do not reuse platinum-tipped
spark plugs by cleaning or regap-ping.
Do not overfill automatic trans-
mission fluid, or the transmissioncould be damaged.
Do not drive with the air cleaner fil-ter removed, or excessive engine
wear could result. Also backfiringcould cause a fire in the enginecompartment.
Be careful not to scratch the glass
surface with the wiper frame.
When closing the engine hood,check to see that you have not for-gotten any tools, rags, etc.
Here is a list of parts and tools you will
need on performing do-it-yourself main-
tenance. Remember all Toyota parts are
designed in metric sizes, so your tools
must be metric.
Checking the engine oil level

 Engine oil API SH, Energy-Conserv-
ing IIº multigrade or ILSAC multigrade

mate
Tools:
 Rag or paper towel
 Funnel (only for adding oil)

ENGINE OIL SELECTION
Use API SH, Energy-Conserving IIº mul-
tigrade engine oil or ILSAC multigrade en-
gine oil.
Recommended oil viscosity (SAE):
Temperature range anticipated before next oil change
60040-L03U
SAE 5W-30 is the best choice for your
vehicle, for good fuel economy, and
good starting in cold weather.
If you use SAE 10W-30 engine oil in
extremely low temperatures, the en-
gine may become difficult to start, so
SAE 5W-30 engine oil is recom-
mended.API service symbol
ILSAC certification mark Oil identification marks
Either or both API registered marks are
added to some oil containers to help
you select the oil you should use.
The API Service Symbol is located any-
where on the outside of the container.
The top portion of the label shows the oil
quality by API (American Petroleum Insti-
tute) designations such as SH. The cen-
ter portion of the label shows the SAE vis-
cosity grade such as SAE 5W-30.
Energy-Conserving
IIº shown in the low-
er portion, indicates that the oil has fuel-
saving capabilities. Oils marked Ener-
gy-Conserving IIº will have higher
fuel-saving capabilities than oil marked
Energy-Conservingº.
The ILSAC (International Lubricant Stan-
dardization and Approval Committee)
Certification Mark is displayed on the front
of the container.
