Smart Brake Support
[Rear Crossing] (SBS-RC)
*
▼ Smart Brake Support [Rear
Crossing]
(SBS-RC)
The SBS-RC is a system designed to
assist the driver in avoiding collisions
and to reduce damage in the event of
a collision by applying the brakes if
there is the possibility of collision with
a vehicle approaching from the rear
while you are reversing out of parking
space.
The SBS-RC system detects vehicles
approaching from the rear left and
right sides of the vehicle, and the rear
of the vehicle while the vehicle is being
reversed out of a parking space, the
system reduces damage in the event of
a collision by operating the brake
control when the system determines
that a collision is unavoidable.
SBS-RC operation
1. The SBS-RC system operates when
the shift lever (manual
transmission) or the selector lever
(automatic transmi ssion) is shifted
to the reverse (R) position.
2. If there is the possibility of a collision with an approaching
vehicle, the SBS-RC system applies
brake and displays “BRAKE!” on the
active driving display and the
multi-information display.
WARNING
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, or animals.
To assure the correct operation of the
SBS-RC, heed the following cautions.
 Do not apply a sticker to a rear radar
and rear camera. Otherwise, the rear
radar and rear camera may not be
able to detect vehicles or
obstructions which could result in an
accident.
 Do not disassemble a rear radar and
rear camera.
