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. 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 ex-
haust gases from entering camper
bodies, trailer or other enclosures
on or around your vehicle. If ex-
haust fumes are detected, open all
windows and thoroughly ventilate the area. 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.
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 the fuel or moisture, making it
appear that the oil level has not changed.
Facts about engine oil consumption

If driving through water, such as
when crossing shallow streams,
first check the depth of the waterand the bottom of the river bed forfirmness. Drive slowly and avoid
deep water.
Take all necessary safety measuresto ensure that damage to the en-
gine or o ther components does not
occur.
Water entering the engine air intake
will cause severe engine damage.
Water can wash the grease fromwheel bearings, causing rustingand premature failure, and mayalso enter the differential,
transmission and transfer case, reducing the gear oil's lubricatingqualities.
Sand and mud that has accumu-lated in brake drums and around
brake discs may affect braking effi-
ciency and may damage brake sys-tem components.
NOTICEAlways perform a maintenance in-spection after each day of off-
road driving that has taken you through rough terrain, sand, mud,
or water. For scheduled mainte-
nance information, refer to theseparate Owner's Manual Sup-plement/Maintenance Scheduleº.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 tocheck 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.
Winter driving tips

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. Rememver all Toyota parts are
designed in metric sizes, so your tools
must be metric. Checking the engine oil level Parts (if level is low): Engine oil API SH, Energy-Conserv-
ing IIº multigrade or ILSAC multigrade

Tools: Rag or paper towel

Checking the engine coolant level Parts (if level is low): Ethylene-glycol antifreeze

Avoid overfilling, or the engine
could be damaged.
Check the oil level on the dipstick
once again after adding the oil.
NOTICEENGINE OIL SELECTION Use API SH, Energy-Conserving IIº mul- tigrade engine oil or ILSAC multigrade en-
gine 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 en-
gine may become difficult to start, so
SAE 5W-30 engine oil is recom-mended.
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 oils marked Energy-Conservingº.
