1. To open the fuel filler door, do this.
Lever typeÐPull up the lever.
Key typeÐTurn the key clockwise in
the fuel filler door.
When refueling, turn off the engine.
CAUTION
Do not smoke, cause sparks or al-
low open flames when refueling.
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. After removing the cap, hang it
on the cap hanger.
It is not unusual to hear a slight swoosh
when the cap is opened. When insta lling,
turn the cap clockwise till you hear aclick.
If the cap is not tightened securely, the
malfunction 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.
CAUTION
Make sure the cap is tightened se-
curely to prevent fuel sp illage in
case of an accident.
Use only a genuine Toyota fuel tank
cap for replacement. It has a built-
in check valve to reduce fuel tank
vacuum.

(c) Front Passenger 's Seat Belt Re-
minder Light
The light remind you to buckle up the
driver 's seat belt.
Once the ignition key is turned to ºONº or
ºSTARTº, the reminder light flashes if a
passenger sits in the front passenger seat
and the front passenger 's seat belt is not
pulled out. Unless the front passenger
starts to pull the shoulder belt out of the
retractor, the light keeps flashing.
If luggage load is placed on the front
passenger seat, depending on its weight
and how it is placed on the seat, built- in
sensors in the seat cushion may detect
the pressure, causing the reminder light to
come on.
(d) Discharge Warning Light
This light warns that the battery is being
discharged.
If it comes on while you are driving, there
is a problem somewhere in the charging
system.
The engine ignition will continue to oper-
ate, however, until the battery is dis-
charged. Turn off the air conditioning,
blower, radio,etc., and drive directly to the
nearest Toyota dealer or repair shop.
NOTICE
Do not continue driving if the engine drive belt is broken or loose.
(e) 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
driving, pull off the road to a safe place
and stop the engine immediately. Call a
Toyota dealer or qualified repair shop for
assistance.
The light may occasionally flicker when
the engine is idling or it may come on
briefly after a hard stop. There is no
cause for concern if it then goes out when
the engine is accelerated slightly.
The light may come on when the oil level
is extremely low. It is not designed to
indicate 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.
(f) Malfunction Indicator Lamp
This lamp comes on in the following
cases.
a. The fuel tank is completely empty. (See
ºFuel gaugeº in Chapter 1- 5 for instruc-
tions.)
b. The fuel tank cap is not tightened se-
curely. (See ºFuel tank capº in Chapter
1- 2 for instructions.)
c. There is a problem somewhere in your
engine or automatic transmission electrical
system.
If it comes on while you are driving in
case b, have your vehicle checked/re-
paired by your Toyota dealer as soon as
possible.
(g) ºABSº 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 driv-
ing, have your vehicle checked by your
Toyota dealer as soon as possible.
The light will come on when the ignition
key is turned to the ºONº position. After
a few seconds, the light will go off.

Keep the trunk lid closed while
driving. An open or unsealed trunk
lid may cause exhaust gases to be
drawn into the vehicle.
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 and the trunk lid closed. Have
the cause immediately located and
corrected.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.
Facts about engine oil
consumption

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 troubledue to insufficient oil.
For detailed information on oil level check,
see ºChecking the engine oil levelº in
Chapter 7- 2.
Your engine is fitted with twin ground
electrode spark plugs.
NOTICE
Use only twin ground electrode spark
plugs for your engine performance.
Brake system
TANDEM MASTER CYLINDER BRAKE SYSTEM
The tandem master cylinder brake system
is a hydraulic system with two separate
sub- systems. If either sub- system s hould
fail, the other will still work. However, the
pedal will be harder to press, and your
stopping distance will be longer. Also, the
brake system warning light may come on.
CAUTION
Do not drive your vehicle with only a
single brake system. Have your
brakes fixed immediately.
BRAKE BOOSTER
The brake booster uses engine vacuum to
power- assist the brakes. If the engine
should quit while you are driving, you can
bring the vehicle to a stop with normal
pedal pressure. There is enough reserve
vacuum for one or two stopsÐbut no
more!

Getting more kilometers/mileage from a
liter/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, causing
greater fuel consumption.
Avoid lengthy warm- up idling. Once
the engine is running smoothly, begin
driving±but 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.
Avoid continuous speeding up and
slowing down. Stop- and- go driving
wastes fuel.
Avoid unnecessary stopping and
braking. Maintain a steady pace. Try
to time the traffic signals so you only
need to stop as little as possible or
take advantage of through streets to
avoid traffic lights. Keep a proper dis-
tance from other vehicles to avoid sud-
den braking. This will also reduce wear
on your brakes.
Avoid heavy traffic or traffic jams
whenever possible.
Do not rest your foot on the clutch
or brake pedal. This causes needless
wear, overheating and poor fuel econo-
my.
Maintain a moderate speed on high-ways. The faster you drive, the greater
the fuel consumption. By reducing your
speed, you will cut down on fuel con-
sumption.
Keep the front wheels in proper
alignment. Avoid hitting the curb and
slow down on rough roads. Improper
alignment not only causes faster tire
wear but also puts an extra load on
the engine, which, in turn, wastes fuel.
Keep the bottom of your vehicle free
from mud, etc. This not only lessens
weight but also helps prevent corro-
sion.
Keep your vehicle tuned- up and in
top shape. A dirty air cleaner, improp-
er valve clearance, dirty plugs, dirty oil
and grease, brakes not adjusted, etc.
all lower engine performance and con-
tribute to poor fuel economy. For longer
life of all parts and lower operating
costs, keep all maintenance work on
schedule, and if you often drive under
severe conditions, see that your vehicle
receives more frequent maintenance
(For schedule maintenance information,
please refer to the separate ºScheduled
Maintenance Guideº or ºOwner 's Manu-
al Supplementº).
CAUTION
Never turn off the engine to coast
down hills. Your power steering and
brake booster will not function with-
out the engine running. Also, the
emission control system operates
properly only when the engine is run-
ning.

Low tire pressure results in excessive
wear, poor handling, reduced fuel econo-
my, and the possibility of blowouts from
overheated 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 w
heel deforma-
tion 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
possibility of tire damage from road haz-
ards.
If a tire frequently needs ref illing, have it
checked by your Toyota dealer.
The following instructions for checking
tire pressure should be observed:
The pressure should be checked only
when the tires are cold. If your ve-
hicle has been packed for at least 3
hours 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
degrade handling and ride.
Take special care when adding air to
the compact spare tire. The smaller
tire size can gain pressure very quick-
ly. Add compressed air in small quanti-
ties and check the pressure often until
it reaches the specified pressure.
Do not bleed or reduce tire pressure
after driving. It is normal for the tire
pressure to be higher after driving.
Never exceed the vehicle capacity
weight. 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 caps
have been lost, have new ones put on
as soon as possible. Checking and replacing tires
Tread wear indicator
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
adjacent grooves, the tire should be re-
placed. 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.).
