Smart Brake Support(SBS)
*
▼Smart Brake Support (SBS)
The SBS alerts the driver of a possible
collision using the wa
rning indications in
the display and a warning sound if the
front radar sensor and Forward Sensing
Camera (FSC) determine that there is the
possibility of a col lision with a vehicle
ahead, pedestrian, or a bicycle.
Furthermore, if a collision is unavoidable,
the automatic brake control is performed
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.
(Vehicles with Drive r Monitoring (DM))
When the SBS determi nes that the driver
is not paying attention to the road using
the driver monitoring camera and it
determines that there is the possibility of a
collision with an obstruction, the SBS
activates the collision warning earlier than
normal.
WA R N I N G
Do not rely completely on the SBS:
The SBS is only designed to reduce damage
in the event of a collision.
The ability to detect obstructions is limited
depending on the obstructions, weather
conditions, or traffic conditions. Over
reliance on the system leading to the
accelerator pedal or brake pedal being
mistakenly operated could result in an
accident.
CAUTION
In the following cases, turn the system off
to prevent an unexpected operation.
 The vehicle is being towed or when
towing another vehicle.
 The vehicle is on a chassis roller.
 When driving on rough roads such as in
areas of dense grass or off-road.
See the next page on how to turn off the
system.

WA R N I N G
Always check the surrounding area visually
before actually putting the vehicle in
reverse:
The system is only designed to assist you in
backing out of the lot when putting the
vehicle in reverse. Due to certain limitations
with the operation of this system, the
SBS-RC system may not operate brake or it
might be delayed even though a vehicle is
behind your vehicle. Always make it your
responsibility as a driver to check the rear.
Do not rely completely on the SBS-RC
system:
The SBS-RC 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 SBS-RC system operates in response
to a vehicle. The system does not operate
in response to obstructions such as a
wall, pedestrians, 2-wheeled vehicles, or
animals.
To assure the correct operation of the
