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.
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.
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 (Search).
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.
-
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 performs driving operations (accelerator operation, steering wheel operation).
-
The accelerator pedal is depressed abruptly.
-
The brake pedal is being depressed.
-
The steering wheel is being operated.
-
The selector lever is being shifted.
-
The turn signal lever is being operated.
-
When warnings and messages, such as a dirty windshield, related to the Forward Sensing Camera (FSC) or front radar sensor are being displayed on the multi-information display.
-
-
The SBS may operate under the 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 crossing a narrow bridge, and passing through low gates, narrow gates, car washing machines, or tunnels.
-
When passing through a toll gate.
-
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.
