Breakin period
Drive gently and avoid high speeds.
Your vehicle does not need an elaborate
breakin. But following a few simple tips for
the first 1600 km (1000 miles) can add to
the future economy and long life of your
vehicle:
Avoid full throttle acceleration when
starting and driving.
Avoid racing the engine.
Try to avoid hard stops during the first
300 km (200 miles).
Do not drive slowly with the manual
transmission in a high gear.
Do not drive for a long time at any
single speed, either fast or slow.
Fuel
FUEL TYPE
Your new vehicle must use only un-
leaded gasoline.
To help prevent gas station mixups, your
Scion has a smaller fuel tank opening. The
special nozzle on pumps with unleaded fuel
will fit it, but the larger standard nozzle on
pumps with leaded gas will not.
At a minimum, the gasoline you use should
meet specifications of ASTM D4814 in the
U.S.A. and CGSB 3.5M93 in Canada.
NOTICE
Do not use leaded gasoline. Use of
leaded gasoline will cause the three
way catalytic converter to lose its ef-
fectiveness and the emission control
system to function improperly. Also,
this can increase maintenance costs.
OCTANE RATING
Select Octane Rating 87 (Research Oc-
tane Number 91) or higher.
Use of unleaded gasoline with an octane rat-
ing or research octane number lower than
stated above will cause persistent heavy
knocking. If it is severe, this will lead to
engine damage.
If your engine knocks...
If you detect heavy knocking even when us-
ing the recommended fuel, or if you hear
steady knocking while holding a steady speed
on level roads, consult your Scion dealer.
However, occasionally, you may notice light
knocking for a short time while accelerating
or driving up hills. This is normal and there
is no need for concern.
GASOLINES CONTAINING DETERGENT
ADDITIVES
Scion recommends the use of gasoline
that contain detergent additives to
avoid buildup of engine deposits.
However, all gasoline sold in the U.S. con-
tains detergent additives to keep clean and/or
clean intake systems.

11 3
QUALITY GASOLINE
Automotive manufacturers in the U.S.,
Europe and Japan have developed a
specification for quality fuel named
WorldWide Fuel Charter (WWFC) that
is expected to be applied worldwide.
The WWFC consists of three categories
that depend on required emission lev-
els. In the U.S., category 3 has been
adopted. The WWFC improves air quali-
ty by providing for better emissions in
vehicle fleets, and customer satisfaction
through better vehicle performance.
CLEANER BURNING GASOLINE
Cleaner burning gasoline, including re-
formulated gasoline that contains oxy-
genates such as ethanol or MTBE is
available in many areas.
Scion recommends the use of cleaner burning
gasoline and appropriately blended reformu-
lated gasoline. These types of gasoline pro-
vide excellent vehicle performance, reduce
vehicle emissions, and improve air quality.OXYGENATES IN GASOLINE
Scion allows the use of oxygenate
blended gasoline where the oxygenate
content is up to 10% ethanol or 15%
MTBE. If you use gasohol in your
Scion, be sure that it has an octane
rating no lower than 87.
Scion does not recommend the use of gaso-
line containing methanol.
GASOLINE CONTAINING MMT
Some gasoline contains an octane en-
hancing additive called MMT (Methylcy-
cropentadienyl Manganese Tricarbonyl).
Scion does not recommend the use of gaso-
line that contains MMT. If fuel containing
MMT is used, your emission control system
may be adversely affected. The Malfunction
Indicator Lamp on the instrument cluster may
come on. If this happens, contact your Scion
dealer for service.GASOLINE QUALITY
In a very few cases, you may experience
drivability problems caused by the particular
gasoline that you are using. If you continue
to have unacceptable drivability, try changing
gasoline brands. If this does not rectify your
problem, then consult your Scion dealer.
NOTICE
Do not use gasohol other than
stated above. It will cause fuel sys-
tem damage or vehicle performance
problems.
If drivability problems are encoun-
tered (poor hot starting, vaporizing,
engine knock, etc.), discontinue the
use.
Take care not to spill gasohol dur-
ing refueling. Gasohol may cause
paint damage.
FUEL TANK CAPACITY
45 L (11.9 gal., 9.9 lmp. gal.)

11 4
Operation in foreign countries
If you plan to drive your Scion in
another country...
First, comply with the vehicle registration
laws.
Second, confirm the availability of the cor-
rect fuel (unleaded and minimum octane
number).
Threeway catalytic converter
The threeway catalytic converter is an
emission control device installed in the
exhaust system.
The purpose is to reduce pollutants in the
exhaust gas.
CAUTION
Keep people and combustible mate-
rials away from the exhaust pipe
while the engine is running. The
exhaust gas is very hot.
Do not drive, idle or park your ve-
hicle over anything that might burn
easily such as grass, leaves, paper
or rags.

11 5
NOTICE
A large amount of unburned gases
flowing into the threeway catalytic
converter may cause it to overheat
and create a fire hazard. To prevent
this and other damage, observe the
following precautions:
Use only unleaded gasoline.
Do not drive with an extremely low
fuel level; running out of fuel could
cause the engine to misfire, creat-
ing an excessive load on the three
way catalytic converter.
Do not allow the engine to run at
idle speed for more than 20 min-
utes.
Avoid racing the engine.
Do not pushstart or pullstart your
vehicle.
Do not turn off the ignition while
the vehicle is moving.
Keep your engine in good running
order. Malfunctions in the engine
electrical system, electronic ignition
system/distributor ignition system
or fuel system could cause an ex-
tremely high threeway catalytic
converter temperature.
If the engine becomes difficult to
start or stalls frequently, take your
vehicle in for a checkup as soon
as possible. Remember, your Scion
dealer knows your vehicle and its
threeway catalytic converter sys-
tem best.
To ensure that the threeway
catalytic converter and the entire
emission control system operate
properly, your vehicle must receive
the periodic inspections required by
the Scion Maintenance Schedule.
For scheduled maintenance
information, refer to the “Scheduled
Maintenance Guide”.
Engine exhaust cautions
CAUTION
Avoid inhaling the engine exhaust.
It contains carbon monoxide, which
is a colorless and odorless gas. It
can cause unconsciousness or even
death.
Make sure the exhaust system has
no holes or loose connections. The
system should be checked from
time to time. If you hit something,
or notice a change in the sound of
the exhaust, have the system
checked immediately.
Do not run the engine in a garage
or enclosed area except for the
time needed to drive the vehicle in
or out. The exhaust gases cannot
escape, making this a particularly
dangerous situation.
Do not remain for a long time in a
parked vehicle with the engine run-
ning. If it is unavoidable, however,
do so only in an unconfined area
and adjust the heating or cooling
system to force outside air into the
vehicle.

11 6
Keep the back door closed while
driving. An open or unsealed back
door 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 back door closed.
Have the cause immediately located
and corrected.
FUNCTIONS OF ENGINE OIL
Engine oil has the primary functions of lubri-
cating and cooling the inside of the engine,
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 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.
More oil is consumed by highspeed driving
and frequent acceleration and deceleration.
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 qts./600 miles, 0.9 lmp. qts./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.
Facts about engine oil
consumption

11 7
As an example, if a vehicle is used for re-
peated short trips, and consumes a normal
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 proper
vehicle maintenance is to keep the engine 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 rec-
ommends 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.
For detailed information on oil level check,
see “Checking the engine oil level” on page
186.
Brake system
The tandem master cylinder brake system is
a hydraulic system with two separate sub
systems. If either subsystem should fail, the
other will still work. However, the pedal will
be harder to press, and your stopping dis-
tance will increase. 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
powerassist 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 reserved vacuum for one or
two stops but no more!

11 8
CAUTION
Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your reserved vacu-
um.
Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hard, much harder than nor-
mal. And your braking distance will
increase.
ANTILOCK BRAKE SYSTEM
The antilock brake system is designed
to automatically help prevent lockup of
the wheels during a sudden braking or
braking on slippery road surfaces. This
assists in providing directional stability
and steering performance of the vehicle
under these circumstances.
Effective way to press the ABS brake
pedal:
When the anti−lock brake system func-
tion is in action, you may feel the brake
pedal pulsating and hear a noise. In this
situation, to let the anti−lock brake sys-
tem work for you, just hold the brake
pedal down more firmly. Do not pump
the brake in a panic stop. This will re-
sult in reduced braking performance.
The antilock brake system becomes opera-
tive after the vehicle has accelerated to a
speed in excess of approximately 10 km/h (6
mph). It stops operating when the vehicle
decelerates to a speed below approximately
5 km/h (3 mph).
Depressing the brake pedal on slippery road
surfaces such as on a manhole cover, a steel
plate at a construction site, joints in a
bridge, etc. on a rainy day tends to activate
the antilock brake system.
You may hear a click or motor sound in the
engine compartment for a few seconds when
the engine is started or just after the vehicle
begins to move. This means that the anti
lock brake system is in the selfcheck mode,
and does not indicate a malfunction.When the antilock brake system is ac-
tivated, the following conditions may
occur. They do not indicate a malfunc-
tion of the system:
You may hear the anti−lock brake sys-
tem operating and feel the brake pedal
pulsating and the vibrations of the ve-
hicle body and steering wheel. You
may also hear the motor sound in the
engine compartment even after the ve-
hicle is stopped.
At the end of the anti−lock brake sys-
tem activation, the brake pedal may
move a little forward.
