Smart Brake Support(SBS)
*
▼Smart Brake Support (SBS)
The SBS alerts the driver of a possible
collision using the warning 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 collision
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 Driver Monitoring
(DM))
When the SBS determines 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.
WARNING
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
o ff 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 o ff-road.
See the next page on how to turn off
the system.
Refer to Stopping the Smart Brake
Support (SBS) System Operation on
page 4-160.

following conditions are met.
The ignition is switched ON.The SBS is on.The i-ACTIVSENSE warning
indication/warning light is not
turned on.
(Object is vehicle ahead)

(2 mph) or higher.
(Object is a pedestrian or bicycle)
The vehicle speed is between about
10 to 80 km/h (6.2 to 50 mph).
The DSC does not operate.
NOTE
Under the following conditions, the
SBS may not operate.
If there is the possibility of hitting
only a part of a vehicle or
obstruction ahead.
You are driving your vehicle at the
same speed as the vehicle ahead.
When the driver deliberately

Smart Brake Support
[Rear] (SBS -R)
*
▼ Smart Brake Support [Rear]
(SBS
-R)
The SBS -R is a system which is
designed to reduce damage in the
event of a collision by operating the
brake control (SBS brake) when the
system’s sensors detect an obstruction
at the rear of the vehicle while driving
at a speed of about 2 to 8 km/h (2 to
4 mph) and the system determines that
a collision is unavoidable.
WARNING
Do not rely completely on the SBS -R
system:
 The
SBS-R 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.
 To assure the correct operation of
the SBS -R, heed the following
cautions.
