Smart Brake Support(SBS)
*
The SBS system alert s the driver of a
possible collision using a display and
warning sound if the radar sensor (front)
and the Forward Sensing Camera (FSC)
determine that there i s the possibility of a
collision with a vehicle ahead while the
vehicle is being driven at about 15 km/h or
faster (10 mph or faster). Furthermore, if
the radar sensor (fr ont) and the Forward
Sensing Camera (FSC) determines that a
collision is unavoidable, the automatic
brake control is p erformed to reduce
damage in the event of a collision.
In addition, w hen the driver depresses the
brake pedal, the brake s are applied firmly
and quickly to assist. (Brake Assist (SBS
brake assist))
WA R N I N G
Do not rely completely on the SBS system
and always drive carefully:
The SBS is designed to reduce damage in
the event of a collision, not avoid an
accident. The ability to detect an
obstruction is limited depending on the
obstruction, weather conditions, or traffic
conditions. Therefore, if the accelerator
pedal or brake pedal is mistakenly
operated it could result in an accident.
Always verify the safety of the surrounding
area and depress the brake pedal or
accelerator pedal while keeping a safer
distance from vehicles ahead or on-coming
vehicles.
CAUTION
In the following cases, turn the system off
to prevent a mis-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.
NOTE
The SBS system operates when all of the
following conditions are met:
The ignition is switched ON.
The SBS system is on.
The vehicle speed is about 15 km/h or
faster (10 mph or faster).
The relative speed between your
vehicle and the vehicle ahead is about
15 km/h or faster (10 mph or faster).
The Dynamic Stability Control (DSC)
is not operating.
The SBS system may not operate under
the following conditions:
If the vehicle is accelerated rapidly
and it comes close to a vehicle ahead.
The vehicle is driven at the same
speed as the vehicle ahead.
The accelerator pedal is depressed.
The brake pedal is depressed.
The steering wheel is being operated.
The selector lever is being operated.
The turn signal is being used.
