When Driving
Drive Selection (Automatic Transaxle) 
●When the sport mode is selected, driving at higher engine speeds increases
and it may increase fuel consumption. Scion recommends that you cancel
the sport mode on normal driving.
● Drive mode cannot be switched in the following conditions:
• ABS/TCS/DSC is operating
• Steering wheel is being operated abruptly
Press the drive selection switch to
the side (forward) to select
the sport mode.
Pull the drive selection switch to
the side (backward) to cancel
the sport mode.
●When the ignition is switched off, the sport mode is canceled.
● Depending on the driving conditions when sport mode is selected, the vehi-
cle may perform shift-down or slightly accelerate.
: If equipped
Drive selection is a system to switch the vehicle’s drive mode.
When the sport mode is selected, vehicle’s response against
accelerator operation is enha nced. This provides additional
quick acceleration which may be needed to safely make maneu-
vers such as lane changes, merging onto free ways, or passing
other vehicles.
WARNING
Do not use the sport mode when driving on slippery roads such as wet or
snow-covered roads. It may cause tire slipping.

When Driving
Power Steering
●Power steering is only operable when the engine is running. If the
engine is off or if the power steeri ng system is inoperable, you can
still steer, but it requires more physical effort.
If the steering feels stiffer than usual during normal driving or the
steering vibrates, cons ult your Scion dealer.
● The warning light notifies the driv er of system abnormalities and
operation conditions.
In addition, the buzzer may also activate depending on the system
abnormality or operation condition.
Refer to Warning Lights on P. 157.
Refer to Power Steering Warning Buzzer on P. 524.
NOTICE
Never hold the steering wheel to the extreme left or right for more than 5
seconds with the engine running. This could damage the power steering
system.

Active Safety System
◆Pre-Crash Safety Technology
Pre-crash safety technology is designed to assist the driver in
averting collisions or re duce their severity in situations where they
cannot be avoided.
● Collision damage reduction in low vehicle speed range
Forward driving:
Smart City Brake Support (SCBS) ( P. 205)
◆Sensor
● Laser sensor
The laser sensor emits a near-infrared laser beam and receives
the beam reflected off the reflec tive surface of a vehicle or
obstruction in front, and the detected beam is then used for mea-
surement. The laser sensor is used for the Smart City Brake
Support (SCBS) system.
The laser sensor is installed at the top of the windshield near the
rearview mirror.
Refer to Laser Sensor on P. 211.

Smart City Brake Support (SCBS)
: If equipped
The Smart City Brake Support (SCBS) system is designed to
reduce damage in the event of a collision by operating the brake
control (SCBS brake) when the system’s laser sensor detects a
vehicle ahead and determines that a collision with a vehicle
ahead is unavoidable. It may also be possible to avoid a colli-
sion if the relative speed between your vehicle and a vehicle
ahead is less than about 12 mph (20 km/h).
In addition, when the driver depresses the brake pedal while the
system is in the operation range at about 2 to 18 mph (4 to
30 km/h), the brakes are applied firmly and quickly to assist.

3-10. Active Safety System
●The Smart City Brake Support (SCBS) system will not operate if the driver is
deliberately performing driving operations (accelerator pedal and steering
wheel).
● The Smart City Brake Support (SCBS) system will operate under the follow-
ing conditions.
• The engine is running.
• The Smart City Brake Support (SCB S) warning light (amber) does not
illuminate.
• The vehicle speed is between about 2 to 18 mph (4 to 30 km/h).
• The Smart City Brake Support (SCBS) system is not turned off.
• The DSC is not malfunctioning.
● The Smart City Brake Support (SCBS) detects a vehicle ahead by emitting a
near-infrared laser beam and receiving the beam reflected off the reflector
of the vehicle ahead, and then using it for the measurement. Consequently,
the Smart City Brake Support (SCBS) may not operate under the following
conditions:
• Reflection of the laser is poor due to the shape of the vehicle ahead.
• The vehicle ahead is significantly dirty.
• Under bad weather condition, such as rain, fog and snow.
• The window washer is being used or the windshield wipers are not used
when it’s raining.
• The windshield is dirty.
• The steering wheel is turned completely left or right, or the vehicle is
accelerated rapidly and comes close to the vehicle ahead.
• Trucks with low loading platforms and vehicles with an extremely low or high profile.
• Vehicles with certain shapes such as a vehicle carrier.
● Under the following conditions, the Smart City Brake Support (SCBS) sys-
tem may not operate normally.
• Heavy luggage is loaded in the luggage compartment or on the rear seat.
• If there is the possibility of partial contact with a vehicle ahead.
• When driving on continuously curving roads, and entering and exiting
exits.
• Elongated luggage or cargo is loaded onto installed roof rails and covers the laser sensor.
• Exhaust gas from the vehicle in front, sand, snow, and water vapor rising
from manholes and grating, and water splashed into the air.
• When towing a malfunctioning vehicle.
• When driving with tires having significantly different wear.

WARNING
■Do not rely on the Smart City Br ake Support System (SCBS) as a sub-
stitute for safer driving
The Smart City Brake Support (SCB S) system cannot compensate for
unsafe and reckless driving, excessive speed, tailgating (following another
vehicle too closely), and driving on slippery roads such as wet, snowy, and
icy roads (reduced tire friction and road contact because of water on the
road surface). You can still have an accident.
■ Do not rely completely on the Sm art City Brake Support (SCBS) system
● The Smart City Brake Support (SCBS) system is only designed to reduce
damage in the event of a collision. Over reliance on the system leading to
the accelerator pedal or brake pedal being mistakenly operated could
result in an accident.
● The Smart City Brake Support (SCB S) is a system which operates in
response to a vehicle ahead. The system may not be able to detect or
react to two-wheeled vehicles or pedestrians.
● The laser sensor for the Smart City Brake Support (SCBS) system is
installed near the rearview mirror. To assure the correct operation of the
Smart City Brake Support (SCBS), heed the following cautions.
• Do not apply stickers to the surface of the windshield near the laser
sensor (including transparent stickers). Otherwise, the laser sensor
may not be able to detect vehicles ahead which could result in an acci-
dent.
• Do not apply coating agent to the windshield. Otherwise, the laser sen- sor may not be able to detect vehicles or obstructions in front which
could result in an accident.
• Do not disassemble the laser sensor.
• If cracks or damage caused by flying gravel or debris is visible near the
laser sensor, stop using the Smart City Brake Support (SCBS) system
immediately and have your vehicle inspected by your Scion dealer. If
the vehicle continues to be driven with cracks or scratch marks left on
the windshield near the laser sensor, the system may operate unneces-
sarily and cause an unexpected accident.
Refer to Stopping The Smart City Br ake Support (SCBS) System Oper-
ation on P. 210.
• When replacing the windshield wipers or windshield, consult your Scion
dealer.
● The laser sensor includes a function for detecting a soiled windshield and
informing the driver, however, depending on the conditions, it may not
detect plastic shopping bags, ice or snow on the windshield. In such
cases, the system cannot accurately determine a vehicle ahead and may
not be able to operate normally. Always drive carefully and pay attention to
the road ahead.

When Driving
If the Smart City Brake Support
(SCBS) is operating, the indicator
light (red) flashes.
●The collision warning beep sounds intermittently while the SCBS brake or
brake assist (SCBS brake assist) is operating.
● If the vehicle is stopped by the SCBS operation and the brake pedal is not
depressed, the warning beep sounds one time after about 2 seconds and
the SCBS brake is automatically released.
WARNING
■Do not modify the suspension
If the vehicle height or inclination is changed, the system will not be able to
correctly detect vehicles ahead. This will result in the Smart City Brake Sup-
port (SCBS) system not operating normally or mistakenly operating, which
could cause a serious accident.
■ Turn off the Smart City Brake Support (SCBS) when the vehicle is run-
ning on a chassis roller or being towed
Turn off the Smart City Brake Support (SCBS) system to prevent mistaken
operation when the vehicle is running on a chassis roller or being towed.
Refer to Stopping The Smart City Brake Support (SCBS) System Operation
on P. 210.
NOTICE
