FUNCTIONS OF ENGINE OIL
Engine oil has the primary functions of
lubricating and cooling the inside of the
engine, and plays a major role in main-
taining 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 pis-
ton 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 combustion
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.The amount of engine oil consumed de-
pends 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.
Oil consumption:
Max. 1.0 L per 1000
km (1.1 qt./600 miles, 0.9 Imp. qt./600
miles)
When judging the amount of oil con-
sumption, note that the oil may become
diluted and make it difficult to judge
the true level accurately.
As an example, if a vehicle is used for
repeated 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
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 at high speeds. IMPORTANCE OF ENGINE OIL LEVEL
CHECK
One of the most important points in prop-
er vehicle maintenance is to keep the en-
gine oil at the optimum level so that oil
function will not be impaired. Therefore, it
is essential 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 level" on
page 436 in Section 7−2.
Facts about engine oil
consumption

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.
Section 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 page 437 in Section 7−2 for recom-
mended viscosity. Leaving a heavy sum-
mer oil in your vehicle during winter
months may cause harder starting. If you
are not sure about which oil to use, call
your Toyota dealerthey 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.
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.NOTICE
Do not use engine antifreeze or any
other substitute because it may dam-
age your vehicle’s paint.
Do not use your parking brake when
there is a possibility it could freeze.
When parking, put the transmission into
P" and block the front wheels. Do not
use the parking brake, or snow or water
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.
Depending on where you are driving,
we recommend you carry some emer-
gency equipment.
Some of the things you might put in the
vehicle are tire chains, window scraper,
bag of sand or salt, flares, small shovel,
jumper cables, etc.CY30020
Your vehicle is not designed to be
dinghy towed (with four wheels on the
ground) behind a motorhome.
NOTICE
Do not tow your vehicle with four
wheels on the ground. This may
cause serious damage to your vehicle.

ENGINE OIL SELECTION
Toyota Genuine Motor Oil" is used in
your Toyota vehicle. Use Toyota approved
Toyota Genuine Motor Oil" or equivalent
to satisfy the following grade and
viscosity.
Oil grade:ILSAC multigrade engine oil
Recommended viscosity: SAE 5W−30
OIL008
Outside temperature
SAE 5W−30 is the best choice for good
fuel economy, and good starting in cold
weather. If SAE 5W−30 oil is not available, SAE
10W−30 oil may be used. However, it
should be replaced with SAE 5W−30 at
the next oil change.
Oil identification mark
The ILSAC (International Lubricant Stan-
dardization and Approval Committee) Certi-
fication Mark is added to some oil con-
tainers to help you select the oil you
should use.

Coolant type: Toyota Super Long Life Coolant" is
used in your Toyota vehicle at factory
fill. In order to avoid technical problems,
only use Toyota Super Long Life
Coolant" or similar high quality ethylene
glycol based non−silicate, non−amine,
non−nitrite, and non−borate coolant with
long−life hybrid organic acid technology.
(Coolant with long−life hybrid organic
acid technology is a combination of low
