strument panel vents.
2. Bi-levelÐ Air flows from both the floor
vents and the instrument panel vents.
3. FloorÐ Air flows mainly from the floor
vents.
4. Floor/WindshieldÐ Air flows mainly
from the floor vents and windshield vents.
5. WindshieldÐ Air flows mainly from
the windshield vents. For details about air flow selector settings, see the illustration after A/Cº button.
Vehicles with A/Cº buttonÐMoving the air flow control lever to wind-
shield position turns on the defroster-
linked air conditioning. At this time, the
A/Cº button indicator comes on regard- less of whether or not the A/Cº button is
pressed in. This is to clean up the front
view more quickly. When the A/Cº button is not pressed in, moving the air flow control lever to anoth-
er position turns off the air conditioning.

tem. A/Cº button
To turn on the air conditioning, press the
A/Cº button. The A/Cº button indicator
will come on. To turn the air conditioning
off, press the button again.
If the A/Cº button indicator flashes, there
is a problem in the air conditioning system
and the air conditioning automatically
shuts off. If this happens, take your ve-
hicle to a Toyota dealer for service.

To cool off your Toyota after it has been
parked in the hot sun, drive with the
windows open for a few minutes. This
vents the hot air, allowing the air condi-
tioning to cool the interior more quickly.
Make sure the air intake g rilles in front
of the windshield are not blocked (by
leaves or snow, for example).
On humid days, do not blow cold air on
the windshield. The windshield could
fog up because of the difference in airtemperature on the inside and outside
of the windshield.
Keep the area under the front seats
clear to allow air to circulate through-out the vehicle.
On cold days, move the fan speed to
HIº for a minute to help clear the in-
take ducts of snow or moisture. This
can reduce the amount of fogging onthe windows.ÐOperating tips

11 2FUNCTIONS 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 combustionprocess.
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 fuel or moisture, making it ap-
pear 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 itappear 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 bechecked every time you refuel the vehicle.
Failure to check the oil level regular-
ly could lead to serious engine
trouble due to insufficient oil.
NOTICE
For detailed information on the oil level
check, see Checking the engine oil levelº
in Chapter 7-2.

Before starting the engine, be sure to fol-
low the instructions in (a) Before crank- ingº.
Normal starting procedure
The multiport fuel injection system/se-
quential multiport fuel injection system in
your engine automatically controls the
proper air-fuel mixture for starting. You can start a cold or hot engine as follows:
1. With your foot off the accelerator ped-
al, crank the engine by turning the key
to STARTº. Release it when the en-
gine starts.
2. After the engine runs for about 10 sec-
onds, you are ready to drive.
If the weather is below freezing, let the en-
gine warm up for a few minutes before driving.
If the engine stalls...
Simply restart it, using the correct proce- dure given in normal starting. If the engine will not startÐ
See If your vehicle will not startº in Part 4.
NOTICE
Avoid driving with the tailgate open.
Do not crank for more than 30 sec-
onds at a time. This may overheatthe starter and wiring systems.
Do not race a cold engine.
If the engine becomes difficult to
start or stalls frequently, have theengine checked immediately.
Always slow down in gusty cross- winds. This will allow you much better control
Drive slowly onto curbs and, if pos-
sible, at a right angle. Avoid driving onto high, sharp-edged objects and
other road hazards. Failure to do so
can lead to server tire damage result- ing in tire bursts.
When parking on a hill, turn the front
wheels until they touch the curb so that
the vehicle will not roll. Apply the park-
ing brake, and place the transmission in Pº (automatic) or in first or reverse
(manual). If necessary, block thewheels.
Washing your vehicle or driving
through deep water may get the
brakes wet. To see whether they are
wet, check that there is no traffic near
you, and then press the pedal lightly. If
you do not feel a normal braking force,
the brakes are probably wet. To dry
them, drive the vehicle cautiously
while lightly pressing the brake pedal
with the parking brake pulled. If they
still do not work safely, pull to the side
of the road and call a T oyota dealer for
assistance.

Tips for driving in various conditions

122
The driver and all passengers
should fasten their seat belts when-
ever the vehicle is moving.
NOTICE
If driving through water, such as
when crossing shallow streams,
first check the depth of the water
and the bottom of the river bed forfirmness. Drive slowly and avoid
deep water.
Take all necessary safety measuresto ensure that water damage to the
engine or other components does
not occur.Water entering the engine air in-
take will cause severe engine dam-age.Water can wash the grease from
wheel bearings, causing rusting and premature failure, and mayalso enter the differentials, trans-
mission and transfer case, reduc-ing the gear oil's lubricating quali-ties.
Sand and mud that has accumu-lated in brake drums and around
brake discs may affect braking ef-
ficiency and may damage brakesystem components.
Always 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 the
separate 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 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.
