Smart City Brake Support (SCBS)*
The SCBS system alerts the driver of a possible collision using an indication in the display
and a warning sound when the Forward Sensing Camera (FSC) detec ts a vehicle ahead and
determines that a collision with a vehicle ahead is unavoidable while the vehicle is being
driven at a vehicle speed of about 4 to 80 km/h (2 to 50 mph). In addition, the system
reduces damage in the event of a collision by operating the bra ke control (Smart City Brake
Support (SCBS) brake) when the system determines that a collisi on is unavoidable while the
vehicle is being driven at a vehicle speed of about 4 to 30 km/ h (2 to 18 mph). It may also
be possible to avoid a collision if the relative speed between your vehicle and the vehicle in
front of you is less than about 20 km/h (12 mph). In addition, when the driver depresses the
brake pedal while the system is i n the operation range at about 4 to 30 km/h (2 to 18 mph),
the brakes are applied firmly and quickly to assist. (Brake Ass ist (Smart City Brake Support
(SCBS) brake assist))

Smart Brake Support (SBS)*
The SBS system alerts 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 is 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 se nsor (front) and the Forward
Sensing Camera (FSC) determines that a collision is unavoidable , the automatic brake
control is performed to reduce da mage in the event of a collision.
In addition, whe n the driver depresses the brake ped al, the brakes 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 de pending 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).
