3. Hold the hood open by inserting the
support rod into the slot.
Before closing the hood, check to see that
you have not forgotten any tools, rags,
etc. and return the support rod to its clipÐthis prevents rattles. Then lower the
hood make sure it locks into place. If nec-
essary, press down gently on the front
edge to lock it.
CAUTION!
After inserting the support rod into
the slot, make sure the rod supports
the hood security.
1. To open the fuel filler door, pull the
lever.
CAUTION!
Do not smoke, cause sparks or al-
low open flames when refuelling.
The fumes are flammable.
When opening the cap, do not re-
move the cap quickly. In hot weath-
er, fuel under pressure could cause
injury by spraying out of the filler
neck if the cap is suddenly re- moved.
2. To remove the fuel tank cap, turn
the cap slowly counterclockwise, then
pause slightly before removing it. Af-
ter removing the cap, hang it on the
cap hanger.
It is not unusual to hear a slight swoosh
when the cap is opened. When installing,
turn the cap clockwise till you hear a click.
If the cap is not tightened securely, themalfunction indicator lamp comes on.
Make sure the cap is tightened securely.
The indicator lamp goes off after driving several times. If the indicator lamp does
not go off, contact your Toyota dealer as soon as possible.

NOTICE
Do not continue driving if the engine drive belt is broken or loose.
(d) Low Oil Pressure Warning Light
This light warns that the engine oil pres-
sure is too low.
If it flickers or stays on while you are driv-
ing, pull off the road to a safe place and
stop the engine immediately. Call a Toyota
dealer or qualified repair shop for assis- tance.
The light may occasionally flicker when
the engine is idling or it may come on brief-
ly after a hard stop. There is no cause for concern if it then goes out when the en-
gine is accelerated slightly.
The light may come on when the oil level
is extremely low. It is not designed to indi-cate low oil level, and the oil level must be checked using the level dipstick.
NOTICE
Do not drive the vehicle with the warning light onÐeven for one
block. It may ruin the engine.
(e) Malfunction Indicator Lamp
This lamp comes on in the following cases.
a. The fuel tank is completely empty. (See Fuel gaugeº in Chapter 1-5 for in- structions.)
b. The fuel tank cap is not tightened se-
curely. (See Fuel tank capº in Chapter
1-2 for instructions.)
c. There is a problem somewhere in your
engine or automatic transmission electri- cal system.
If it comes on while you are driving in case
c, have your vehicle checked/repaired by
your Toyota dealer as soon as possible.
(f) Low Fuel Level Warning Light
This light comes on when the fuel level in
the tank becomes nearly empty. Fill up the
tank as soon as possible.
(g) ABSº Warning Light
This light warns that there is a problem
somewhere in your anti-lock brake sys- tem.
If the light comes on while you are driving,
have your vehicle checked by your T oyota
dealer as soon as possible. The light will come on when the ignition key is turned to the ONº position. After
about 3 seconds, the light will go off. When the ABSº warning light is on (and
the brake system warning light is off), the brake system
operates conventionally but
without anti-lock function.
(h) Open Door Warning Light
This light remains on until all the doors
and back door are completely closed.
(i) SRS Airbag Warning Light
This light will come on when the igni-
tion key is turned to the ACCº or ONº
position. After about 6 seconds, the
light w ill go off. This means the airbag
system is operating properly.
The warning light system monitors the air-
bag sensor assembly, inflators, warning
light, interconnecting wiring and power sources.
If either of the following conditions occurs, this indicates a malfunction somewhere in the parts monitored by the warning light
system. Contact your Toyota dealer as
soon as possible to service the vehicle. The light does not come on when the
ignition key is turned to the ACCº or
ONº position or remains on.
The light comes on while driving.

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 isleft 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 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 itappear that oil is excessively consumed
after driving at 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.
NOTICE
Failure to check the oil level regular- ly could lead to serious engine
trouble due to insufficient oil.
For detailed information on the oil level
check, see Checking the engine oil levelº
in Chapter 7-2.
Facts about engine oil consumption

148When restarting out after parking on a slope:
1. With the transmission in Pº position
(automatic) or
the clutch pedal depressed
(manual), start the engine. (With an auto-
matic transmission, be sure to keep thebrake pedal depressed.)
2. Shift into gear.
3. Release the parking brake (also foot
brake on automatic transmission ve-
hicles) and slowly pull or back away from
the wheel blocks. Stop and apply yourbrakes.
4. Have someone retrieve the blocks.
CAUTION!
Do not exceed 72 km/h (45 mph) or
the posted towing speed limit,
whichever is lower. Because in-
stability (swaying) of a towing ve-
hicle-trailer combination usually
increases as the speed increases,
exceeding 72 km/h (45 mph) maycause loss of control.
Slow down and downshift before
descending steep or long downhill
grades. Do not make suddendownshifts.
Avoid holding the brake pedal
down too long or too frequently.
This could cause the brakes to
overheat and result in reduced
braking efficiency. Getting
more kilometers/mileage from a li-
ter/gallon of fuel is easyÐjust take it easy.
It will help make your vehicle last longer,
too. Here are some specific tips on how to
save money on both fuel and repairs: Keep your tires inflated at the cor- rect pressure. Underinflation causes
tire wear and wastes fuel. See Chapter
7-2 for instructions.
Do not carry unneeded weight in
your vehicle. Excess weight puts a
heavier load on the engine, causinggreater fuel consumption.
Avoid lengthy warm-up idling.
Once the engine is running smoothly,
begin drivingÐbut gently. Remember,
however, that on cold winter days this
may take a little longer.
Accelerate slowly and smoothly.
Avoid jackrabbit starts. Get into high
gear as quickly as possible.
Avoid long engine idling. If you have
a long wait and you are not in traffic, it
is better to turn off the engine and start
again later.
Avoid engine lug or overrevving.
Use a gear position suitable for the
road on which you are travelling.
How to save fuel and make
your vehicle last longer, too

191
Keep your tire pressures at the proper level.
The recommended cold tire pressures,
tire size and the cargo weight rating are
given in Part 8.
You should check the tire pressures every
two weeks, or at least once a month. And
do not forget the spare!
Incorrect tire pressure can reduce tire
life and make your vehicle less safe todrive.
Low tire pressure results in excessive
wear, poor handling, reduced fuel econo-
my, and the possibility of blowouts fromoverheated tires. Also, low tire pressure
can cause poor sealing of the tire bead. If
the tire pressure is excessively low, there
is the possibility of wheel deformation and/or tire separation.
High tire pressure produces a harsh ride,
handling problems, excessive wear at the center of the tire tread, and a greater
pos-
sibility of tire damage from road hazards.
If a tire frequently needs refilling, have it
checked by your Toyota dealer. The following instructions for check-
ing tire pressure should be observed:
The pressure should be checked
only when the tires are cold. If your
vehicle has been parked for at least 3hours and has not been driven for
more than 1.5 km or 1 mile since, you
will get an accurate cold tire pressure reading.
Always use a tire pressure gauge.
The appearance of a tire can be mis-
leading. Besides, tire pressures that
are even just a few pounds off can de-
grade handling and ride.
Do not bleed or reduce tire pres-sure after driving. It is normal for the
tire pressure to be higher after driving.
Never exceed the vehicle capacityweight. The passenger and luggage
weight should be located so that the
vehicle is balanced.
Be sure to reinstall the tire inflation
valve caps. Without the valve caps,
dirt or moisture could get into the valve
core and cause air leakage. If the capshave been lost, have new ones put onas soon as possible.
CHECKING YOUR TIRES Check the tire tread for the tread wear
indicators. If the indicators show, re-
place the tires.
The tires on your Toyota have built-in tread wear indicators to help you know
when the tires need replacement. When
the tread depth wears to 1.6 mm (0.06 in.)
or less, the indicators will appear. If you
can see the indicators in two or more adja-
cent grooves, the tire should be replaced.
The lower the tread, the higher the risk of skidding. The effectiveness of snow tires is lost
if the tread wears down below 4 mm (0.16 in.).
