Installation of a mobiletwo–way radio system
As the installation of a mobile two–way radio system in
your vehicle could affect electronic systems such as
multiport fuel injection system/sequential multiport fuel
injection system, cruise control system, anti–lock brake
system, SRS airbag system and seat belt pretensioner
system, be sure to check with your Scion dealer for
precautionary measures or special instructions regarding
installation.
Tires and loading on your Scion
Underinflated or overinflated tire inflation pressure
and the excess load may result in the deterioration
of steering ability and braking ability, leading to
an accident. Check the tire inflation pressure peri-
odically and be sure to keep the load limits given
in this Owner ’s Manual. For details about tire infla-
tion pressure and load limits, see page 237 and
page 174.

CAUTION
After inserting the support rod into
the slot, make sure the rod supports
the hood securely from falling down
on to your head or body.
NOTICE
Be sure to return the support rod to
its clip before closing the hood. Clos-
ing the hood with the support rod up
could cause the hood to bend.

1. To open the fuel filler door, pull thelever up.
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, turnthe cap counterclockwise by 90 de-
grees (to the pressure point 1), and
then turn it an additional 30 degrees
(to point 2). Pause slightly before
removing it.
Although a click will be heard as you turn
the cap to point 1, it does not indicate
that the cap can be removed.
It is not unusual to hear a slight swoosh
when the cap is opened.
12T028
3. The removed cap can be stored on the back side of the fuel filler door.
Position the cap so that the hooks point
to the left and right, and set it in the
receptacle on the back side of the door.
When installing the cap, turn the cap
clockwise until you hear one click.
When you hear the click, the cap is
fully closed.
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 Scion dealer as
soon as possible.
CAUTION
Make sure the cap is tightened se-
curely to prevent fuel sp illage in
the event of an accident.
Use only a genuine fuel tank cap
for replacement. It is designed to
regulate fuel tank pressure.
NOTICE
To prevent damage to the cap, ob-
serve the following precautions.
 Apply force only in the turning di-
rection to the cap. Do not pull or
pry it.
 Do not tighten the cap further after
you hear one click when installing.

107
If the system fails to reset, the light will
remain on or keep flashing.
(f) Malfunction Indicator Lamp
This lamp comes on when the engine
switch is turned to the “ON” position
and goes off after the engine starts.
This means that the warning light sys-
tem is operating properly.
If the lamp remains on or the lamp
comes on while driving, first check the
following.
Empty fuel tank
If the fuel tank is empty, refuel immedi-
ately.
Loose fuel tank cap
If the fuel tank cap is loose, securely
tighten it.
These cases are temporary malfunctions.
The malfunction indicator lamp will go off
after taking several driving trips.
If the lamp will not go off even after
the several trips, contact your Scion
dealer as soon as possible. If the fuel tank is not empty or the fuel
tank cap is not loose...
There is a problem somewhere in the
engine, emission control system, auto-
matic transmission electrical system or
warning light system itself.
Contact your Scion dealer as soon as
possible to service the vehicle.
Emissions Inspection and Maintenance
(I/M) programs
Your vehicle may not pass a state emis-
sion inspection if the malfunction indicator
lamp remains on. Contact your Scion deal-
er to check your vehicle’s emission control
system and OBD (On–Board Di agnostics)
system before taking your vehicle for the
inspection.
For details, see “Emissions inspection and
maintenance (I/M) programs” on page 222.
(g) Low Fuel Level Warning Light
This light comes on when the fuel level
in the tank becomes very low. Fill up the
tank as soon as possible.
On inclines or curves, due to the move-
ment of fuel in the tank, the low fuel level
warning light may come on earlier than
usual. (h) Low Engine 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
Scion 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 on—even for one block.
It may ruin the engine.

109
The SRS warning light and “AIR BAG
OFF” indicator light will come on if there
is a malfunction in the front passenger
occupant classification system.
(l) Tire Pressure Warning Light
This light comes on when the engine
switch is turned to the “ON” position. If
the tire pressure warning system works
properly and tire inflation pressure is ap-
propriate, the light goes off after a few
seconds.
This light comes on or comes on after
blinking for 1 minute in the following
cases when the engine switch is turned to
the “ON” position.
When a low tire inflation pressure is
detected while driving...
If any tire has low inflation pressure,
the light comes on.
The light goes off after the tire inflation
pressure is adjusted to a specified lev-
el.
When initializing the system...
If initialization is accepted, the light
blinks slowly three times.
When the system malfunctions...
If the system malfunctions, the light
comes on after blinking for 1 minute.Although it is no problem to continue
driving, have your vehicle checked by
your Scion dealer as soon as possible.
(m) Key Reminder Buzzer
This buzzer acts as a reminder to remove
the key when you open the driver’s door
with the engine switch in the “ACC” or
“LOCK” position. CHECKING SERVICE REMINDER
INDICATORS (except the low fuel level
warning light)
1. Apply the parking brake.
2. Open either side door or back door. The open door warning light should
come on.
3. Close the door. The open door warning light should go
off.
4. Turn the engine switch to the “ON” position, but do not start the engine.
All the service reminder indicators except
the open door warning light should come
on. The “ABS” warning light, “MAINT
REQD” reminder light and tire pressure
warning light go off after a few seconds.
The SRS warning light goes off after
about 6 seconds.
If any service reminder indicator or warn-
ing buzzer does not function as described
above, have it checked by your Scion
dealer as soon as possible.

11 9
As an added safety feature, your ve-
hicle has been equipped with a tire
pressure monitoring system (TPMS–
tire pressure warning system) that il-
luminates a low tire pressure telltale
(tire pressure warning light) when one
or more of your tires is significantly
underinflated. Accordingly, when the
low tire pressure telltale (tire pres-
sure warning light) illuminates, you
should stop and check your tires as
soon as possible, and inflate them to
the proper pressure. Driving on a sig-
nificantly underinflated tire causes
the tire to overheat and can lead to
tire failure. Underinflation also re-
duces fuel efficiency and tire tread
life, and may affect the vehicle’s han-
dling and stopping ability.
Please note that the TPMS (tire pres-
sure warning system) is not a substi-
tute for proper tire maintenance, and
it is the driver ’s responsibility to
maintain correct tire pressure, even if
underinflation has not reached the
level to trigger illumination of the
TPMS low tire pressure telltale (tire
pressure warning light).Your vehicle has also been equipped
with a TPMS (tire pressure warning
system) malfunction indicator to indi-
cate when the system is not operat-
ing properly. The TPMS (tire pressure
warning system) malfunction indicator
is combined with the low tire pres-
sure telltale (tire pressure warning
light). When the system detects a
malfunction, the telltale will flash for
approximately one minute and then
remain continuously illuminated. This
sequence will continue upon subse-
quent vehicle startups as long as
the malfunction exists. When the mal-
function indicator is illuminated, the
system may not be able to detect or
signal low tire pressure as intended.TPMS (tire pressure warning system)
malfunctions may occur for a variety
of reasons, including the installation
of replacement or alternate tires or
wheels on the vehicle that prevent
the TPMS (tire pressure warning sys-
tem) from functioning properly. Al-
ways check the TPMS (tire pressure
warning system) malfunction telltale
after replacing one or more tires or
wheels on your vehicle to ensure that
the replacement or alternate tires and
wheels allow the TPMS (tire pressure
warning system) to continue to func-
tion properly.

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.
Oil consumption: Max. 1.0 L per 1000
km (1.1 qt./600 miles, 0.9 lmp.qt./600
miles)
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.
The diluting ingredients evaporate out
when the vehicle is then driven at high
speeds, as on an express way, 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. Scion 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 trouble
due to insufficient oil.

Tr ailer to win g
Scion does not recommend towing a
trailer with your vehicle. Scion also
does not recommend the installation of
a tow hitch or the use of a tow hitch
carrier for a wheelchair, scooter, bi-
cycle, etc. Your Scion is not designed
for trailer towing or for the use of tow
hitch mounted carriers.Improving fuel economy is easy–just 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 page
237 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, howev-
er, that on cold winter days this may
take a little longer.
Keep the automatic transmission
shift lever into “D” when engine
braking is not required. Driving with
the shift lever in “3” will reduce the
fuel economy. (For details, see “Auto-
matic transmission” on page 113.)
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 lugging or over–rev-
ving. 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.
