In order to be effective, the SRS airbags must deploy
with tremendous speed. The rapid deployment of the
SRS airbags makes the SRS airbags themselves poten-
tial sources of injury if an occupant is too close to an
airbag, or if an object or some part of his or her body
has been placed between the occupant and the airbag
at the time of deployment. This is just one example of
how the instructions in Section 1−3 of this Owner’s
Manual will help ensure proper use of the occupant
restraint systems, and increase the safety they can pro-
vide to you and your family in the event of an accident.
Scion recommends you to read the provisions in Section
1−3 carefully and refer to them from time to time during
your time of ownership of this vehicle.New vehicle warranty
Your new vehicle is covered by the following Scion lim-
ited warranties:
 New vehicle warranty

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 Diagnostics)
system before taking your vehicle for the
inspection.
For details, see “Emissions inspection and
maintenance (I/M) programs” on page 176.
(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.
(i) “ABS” Warning Light
The light comes on when the ignition key
is turned to the “ON” position. If the anti−
lock brake system works properly, the
light turns off after a few seconds. There-
after, if the system malfunctions, the light
comes on again.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti−lock brake system does not operate,
but the brake system still operates con-
ventionally.
When the “ABS” warning light is on (and
the brake system warning light is off), the
anti−lock brake system does not operate
so that the wheels could lock up during
sudden braking or braking on slippery
road surfaces.
If either of the following conditions
occurs, this indicates a malfunction
somewhere in the components moni-
tored by the warning light system.
Contact your Scion dealer as soon as
possible to service the vehicle.

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 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 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!

142
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 tunedup and in
top shape. A dirty air cleaner,
improper valve clearance, dirty plugs,
dirty oil and grease, brakes not
adjusted, etc. all lower engine
performance and contribute 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 scheduled maintenance
information, please refer to the
“Scheduled Maintenance Guide”.)
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.
