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.
Refer to Stopping the Smart Brake
Support (SBS) System Operation on page
4-157.
Operation conditions
The SBS operates when all of the
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)
The vehicle speed is about 4 km/h (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.

following conditions.
There is an object in the road at the
entrance to a curve (including
guardrails and snow banks).
Passing an approaching vehicle while
rounding a curve.

When entering an underground
parking area.
There is a metal object, bump, or a
protruding object on the road.
If you suddenly come close to a
vehicle ahead.
There is an animal, wall, or tree.
Notifies the driver with a warning
indication on the multi-information
display and the active driving display
(vehicles with active driving display)
while the system is operating.
If a malfunction is detected or the
system temporarily stops the function
due to dirty sensors (such as radar
sensor or Forward Sensing Camera
(FSC)), the i-ACTIVSENSE warning
indication/warning light turns on and a
message is displayed on the
multi-information display.
On a manual transmission vehicle, the
engine stops if the clutch pedal is not
depressed when the vehicle is stopped by
the SBS brake operation.
If the vehicle is stopped by the SBS
brake operation and the brake pedal is
not depressed, the SBS brake is
automatically released after about 2
seconds.
▼ Collision Warning
When there is a possib
ility of a collision
with a vehicle ahead, the collision warning
sound is activated continuously and a

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.
WA R N I N G
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.
