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
vehicle, drive with the windows
open. Have the cause immediately
located and corrected.
Toyota does not recommend occu-
pying the rear cargo area when it
is fitted with a slide- in camper,
camper shell or other type cover
while the engine is running. This
caution applies to both driving and
stopped or parked situations with
the engine running. Particular care
should be taken to prevent exhaust
gases from entering camper bodies,
trailers or other enclosures on or
around your vehicle. If exhaust
fumes are detected, open all win-
dows and thoroughly ventilate the
area.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.
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.

Sand and mud that has accumulated
in brake drums and around brakediscs may affect braking efficiency and may damage brake system com-
ponents.
Always perform a maintenance in-spection after each day of off- road
driving that has taken you throughrough terrain, sand, mud, or water.For scheduled maintenance in-
formation, refer to the separateºScheduled Maintenance Guideº orºOwner 's Manual Supplementº.
Winter driving tips
Make sure you have a proper freeze
protection of engine coolant.
Your coolant must contain ethylene- glycol
type coolant for a proper corrosion
protection of aluminum components. Use
ºToyota Long Life Coolantº or equivalent.
See Chapter 7- 2 for details about coolant
type selection.
NOTICE
Do not use alcohol type antifreeze or
plain water alone.
When it is extremely cold, we recommend
to use 60% solution for your Toyota, to
provide protection down to about -50 5C
(- 58 5F). Do not use more than 70% solu-
tion for better coolant performance.
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 start-
ing. Chapter 7- 3 tells you how to visually
inspect 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 viscos-
ity. 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
inserting it.
Use a washer fluid containing an ant-
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.

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.
Parts and tools
Here is a list of parts and tools you will
need on performing do- it- yourself mainte-
nance. Remember all Toyota parts are de-
signed in metric sizes, so your tools must
be metric.
Checking the engine oil level
Parts (if level is low):
Engine oil API grade SJ,
ºEnergy- Conservingº or ILSAC
multigrade having viscosity proper for
your climate
Tools: Rag or paper towel
Funnel (only for adding oil)
Checking the engine coolant level
Parts (if level is low): ºToyota Long Life Coolantº or equiva-
lent
See Chapter 7- 2 for details about cool-
ant type selection.
Demineralized or distilled water
Tools:
Funnel (only for adding coolant) Checking brake fluid
Parts (if level is low):
SAE J1703 or FMVSS No.116 DOT 3
brake fluid

Parts (if level is low): Automatic transmission fluid DEXRON II
or III
Tools: Rag or paper towel

NOTICE
Avoid overfilling, or the engine could be damaged.
Check the oil level on the dipstickonce again after adding the oil.
Engine oil selection
Use API grade SJ, ºEnergy- Conservingº
or ILSAC multigrade engine oil.
Recommended viscosity (SAE):
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 engine
may become difficult to start, so SAE
5W- 30 engine oil is recommended.
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 SJ. The center
portion of the label shows the SAE viscos-
ity grade such as SAE 5W- 30. ºEnergy-
Conservingº shown in the lower portion,
indicates that the oil has fuel- saving ca-
pabilities.
The ILSAC (International Lubricant Stan-
dardization and Approval Committee) Certi-
fication Mark is displayed on the front of
the container.
