For your information
Main Owner’s Manual
Please note that this manual applies to all models and all equipment, includ-
ing options. Therefore, you may find some explanations for equipment not
installed on your vehicle.
All specifications provided in this manual are current at the time of printing.
However, because of the Scion policy of continual product improvement, we
reserve the right to make changes at any time without notice.
Depending on specifications, the vehicle shown in the illustrations may differ
from your vehicle in terms of equipment.
Noise from under vehicle after turning off the engine
Approximately five hours after the engine is turned off, you may hear sound
coming from under the vehicle for several minutes. This is the sound of a fuel
evaporation leakage check and, it does not indicate a malfunction.
Accessories, spare parts and modification of your Scion
A wide variety of non-genuine spare parts and accessories for Scion vehicles
are currently available in the market. You should know that Toyota does not
warrant these products and is not responsible for their performance, repair,
or replacement, or for any damage they may cause to, or adverse effect they
may have on, your Scion vehicle.
This vehicle should not be modified with non-genuine Scion products.
Modification with non-genuine Scion products could affect its performance,
safety or durability, and may even violate governmental regulations. In
addition, damage or performance problems resulting from the modification
may not be covered under warranty.

Installation of a mobile two-way radio system
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
● Anti-lock brake system
● SRS airbag system
● Seat belt pretensioner system
Be sure to check with your Scion dealer for precautionary measures or spe-
cial instructions regarding installation of a mobile two-way radio system.
Vehicle data recordings
Your Scion is equipped with several sophisticated computers that will record
certain data, such as:
• Engine speed
• Accelerator status
• Brake status
• Vehicle speed
• Shift position
The recorded data varies according to the vehicle grade level and options
with which it is equipped. Furthermore, these computers do not record con-
versations, sounds or pictures.
● Data usage
Scion may use the data recorded in these computers to diagnose malfunc-
tions, conduct research and development, and improve quality.
Scion will not disclose the recorded data to a third party except:
• With the consent of the vehicle owner or with the consent of the lessee if the vehicle is leased
• In response to an official request by the police, a court of law or a govern- ment agency
• For research purposes where the data is not tied to a specific vehicle or vehicle owner

104 2-1. Driving procedures
■Operating your vehicle in a foreign country
Comply with the relevant vehicle registration laws and confirm the availability
of the correct fuel. ( P. 319)
CAUTION
■When starting the vehicle
Always keep your foot on the brake pedal while stopped with the engine run-
ning. This prevents the vehicle from creeping.
■ When driving the vehicle
●Do not drive if you are unfamiliar with the location of the brake and accel-
erator pedals to avoid depressing the wrong pedal.
• Accidentally depressing the accelerator pedal instead of the brake
pedal will result in sudden acceleration that may lead to an accident
that could result in death or serious injury.
• When backing up, you may twist your body around, leading to a diffi- culty in operating the pedals. Make sure to operate the pedals properly.
• Make sure to keep a correct driving posture even when moving the vehicle only slightly, allowing you to depress the brake and accelerator
pedals properly.
• Depress the brake pedal using your right foot. Depressing the brake pedal using your left foot may delay response in an emergency, result-
ing in an accident.
● Do not drive the vehicle over or stop the vehicle near flammable materials.
The exhaust system and exhaust gases can be extremely hot. This may
cause a fire if there is any flammable material nearby.
● Do not let the vehicle roll backward while the shift lever is in a driving posi-
tion, or roll forward while the shift lever is in R.
Doing so may cause the engine to stall or lead to poor brake and steering
performance, resulting in an accident or damage to the vehicle.
● If the smell of exhaust is noticed inside the vehicle, open the windows and
check that the back door is closed. Large amounts of exhaust in the vehi-
cle can cause driver drowsiness and an accident, resulting in death or a
serious health hazard. Have the vehicle inspected by your Scion dealer
immediately.

When driving
CAUTION
■
When driving the vehicle
●Do not shift the shift lever to P while the vehicle is moving.
Doing so can damage the transmission and may result in a loss of vehicle\
control.
● Do not shift the shift lever to R while the vehicle is moving forward.
Doing so can damage the transmission and may result in a loss of vehicle\
control.
● Do not shift the shift lever to D while the vehicle is moving backward.
Doing so can damage the transmission and may result in a loss of vehicle\
control.
● Moving the shift lever to N while the vehicle is moving will disengage the
engine from the transmission. Engine braking is not available when N is
selected.
● During normal driving, do not turn off the engine. Turning the engine off
while driving will not cause loss of steering or braking control, but the
power assist to these systems will be lost. This will make it more difficult to
steer and brake, so you should pull over and stop the vehicle as soon as it
is safe to do so.
However, in the event of an emergency, such as if it becomes impossible
to stop the vehicle in the normal way. ( P. 313)
● Use engine braking to maintain a safe speed when driving down a steep
hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. ( P. 114)
● When stopped on an inclined surface, use the brake pedal and parking
brake to prevent the vehicle from rolling backward or forward and causing
an accident.
● Do not adjust the position of the steering wheel, the seat, or the inside or
outside rear view mirrors while driving.
Doing so may result in a loss of vehicle control that can cause accidents
that may result in death or serious injury.
● Always check that all passengers' arms, heads or other parts of their bod-
ies are not outside the vehicle, as this may result in death or serious injury.

106 2-1. Driving procedures
CAUTION
■When driving the vehicle
●Do not drive in excess of the speed limit. Even if the legal speed limit per-
mits it, do not drive over 85 mph (140 km/h) unless your vehicle has high-
speed capability tires. Driving over 85 mph (140 km/h) may result in tire
failure, loss of control and possible injury. Be sure to consult a tire dealer
to determine whether the tires on your vehicle are high-speed capability
tires or not before driving at such speeds.
■ When driving on slippery road surfaces
●Sudden braking, acceleration and steering may cause tire slippage and
reduce your ability to control the vehicle, resulting in an accident.
● Sudden changes in engine speed, such as engine braking caused by up-
shifting or down-shifting, may cause the vehicle to skid, resulting in an
accident.
● After driving through a puddle, lightly depress the brake pedal to make
sure that the brakes are functioning properly. Wet brake pads may prevent
the brakes from functioning properly. If the brakes on only one side are wet
and not functioning properly, steering control may be affected, resulting in
an accident.
■ When shifting the shift lever
Be careful not to shift the shift lever with the accelerator pedal depressed.
This may lead to unexpected rapid acceleration of the vehicle that may
cause an accident and result in death or serious injury.
■ When the vehicle is stopped
●Do not race the engine.
If the vehicle is in any gear other than P or N, the vehicle may accelerate
suddenly and unexpectedly, and may cause an accident.
● Do not leave the vehicle with the engine running for a long time.
If such a situation cannot be avoided, park the vehicle in an open space
and check that exhaust fumes do not enter the vehicle interior.
● In order to prevent accidents due to the vehicle rolling away, always keep
depressing the brake pedal while the engine is running, and apply the
parking brake as necessary.

108 2-1. Driving procedures
CAUTION
■Exhaust gases
Exhaust gases include harmful carbon monoxide (CO) that is colorless and
odorless. Inhaling exhaust gases may lead to death or a serious health haz-
ard.
●If the vehicle is in a poorly ventilated area, stop the engine. In a closed
area, such as a garage, exhaust gases may collect and enter the vehicle.
This may lead to death or a serious health hazard.
● The exhaust should be checked occasionally. If there is a hole or crack
caused by corrosion, damage to a joint or abnormal exhaust noise, be
sure to have the vehicle inspected and repaired by your Scion dealer. Fail-
ure to do so may allow exhaust gases to enter the vehicle, resulting in
death or a serious health hazard.
■ When taking a nap in the vehicle
Always turn the engine off. Otherwise, you may accidentally move the shift
lever or depress the accelerator pedal, which could cause an accident or fire
due to engine overheating. Additionally, if the vehicle is parked in a poorly
ventilated area, exhaust gases may collect and enter the vehicle, leadin\
g to
death or a serious health hazard.
■ When braking the vehicle
●When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and may cause one
side of the vehicle to brake differently than the other side. Also the parking
brake may not securely hold the vehicle.
● If the power brake assist function does not operate, do not follow other
vehicles closely and avoid downhills or sharp turns that require braking.
In this case, braking is still possible, but it will require more force on the
pedal than usual. Braking distance may also increase.
● Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted
brakes.

110 2-1. Driving procedures
NOTICE
■If you get a flat tire while driving
A flat or damaged tire may cause the following situations. Hold the steering
wheel firmly and gradually press the brake pedal to slow down the vehicle.
●It may be difficult to control your vehicle.
● The vehicle will make abnormal sounds.
● The vehicle will behave abnormally.
If a tire goes flat, confirm the extent of the damage to the tire.
● If the tire is reparable, complete the emergency repair procedure.
( P. 284)
● If the tire is irreparable, please contact your Scion dealer.
■ When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may
cause the following serious damage to the vehicle.
●Engine stalling
● Short in electrical components
● Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be
sure to have your Scion dealer check the following.
● Brake function
● Changes in quantity and quality of eng ine oil, transmission fluid, etc.
● Lubricant condition for the bearings and suspension joints (where possi-
ble) and the function of all joints, bearings, etc.
