Smart City Brake Support (SCBS)*
The SCBS system alerts the driver of a possible collision using an indication in the display
and a warning sound when the Forward Sensing Camera (FSC) detects a vehicle ahead and
determines that a collision with a vehicle ahead is unavoidable while the vehicle is being
driven at a vehicle speed of about 4 to 80 km/h (2 to 50 mph). In addition, the system
reduces damage in the event of a collision by operating the brake control (Smart City Brake
Support (SCBS) brake) when the system determines that a collision is unavoidable while the
vehicle is being driven at a vehicle speed of about 4 to 30 km/h (2 to 18 mph). It may also
be possible to avoid a collision if the relative speed between your vehicle and the vehicle in
front of you is less than about 20 km/h (12 mph). In addition, when the driver depresses the
brake pedal while the system is in the operation range at about 4 to 30 km/h (2 to 18 mph),
the brakes are applied firmly and quickly to as sist. (Brake Assist (Smart City Brake Support
(SCBS) brake assist))

Do not rely completely on the SCBS system:
 The SCBS system is only designed to reduce da mage 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 SCBS is a system which operates in response to a vehicle ahead. The system may not be
able to detect or react to 2-wheeled vehicles or pedestrians.

Smart Brake Support
(SBS)
*
The SBS system alerts the driver of a
possible collision using a display and
warning sound if the radar sensor (front)
and the Forward Sensing Camera (FSC)
determine that there is the possibility of a
collision with a vehicle ahead while the
vehicle is being driven at about 15 km/h or
faster (10 mph or faster). Furthermore, if
the radar sensor (front) and the Forward
Sensing Camera (FSC) determines that a
collision is unavoidable, the automatic
brake control is pe rformed to reduce
damage in the event of a collision.
In addition, when the driver depresses the
brake pedal, the brakes are applied firmly
and quickly to assist. (Brake Assist (SBS
brake assist))
WA R N I N G
Do not rely completely on the SBS system
and always drive carefully:
The SBS is designed to reduce damage in
the event of a collision, not avoid an
accident. The ability to detect an
obstruction is limited depending on the
obstruction, weather conditions, or traffic
conditions. Therefore, if the accelerator
pedal or brake pedal is mistakenly
operated it could result in an accident.
Always verify the safety of the surrounding
area and depress the brake pedal or
accelerator pedal while keeping a safer
distance from vehicles ahead or on-coming
vehicles.

Forward Sensing Camera (FSC)
The Forward Sensing Camera (FSC) determines the conditions ahead of the vehicle while
traveling at night and detects traffic lanes. The distance in which the Forward Sensing
Camera (FSC) can detect objects varies depending on the surrounding conditions.
WA R N I N G
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 system not operating normally or mistakenly operating,
which could cause a serious accident.
CAUTION
 Do not apply accessories, stickers or film to the windshield near the Forward Sensing
Camera (FSC).
If the area in front of the Forward Sensing Cam era (FSC) lens is obstructed, it will cause the
system to not operate correctly. Consequently, each system may not operate normally
which could lead to an unexpected accident.
