Warning sound volume
Types of warnings (steering wheel vibration/beep sound/rumble sound*1)
*1 A rumble strip is a series of grooves in the road pavement surface positioned at specific
intervals, and when the vehicle passes over it a vibration and rumble sound is produced
which alerts the driver that the vehicle is departing from the lane.
The rumble sound is a reproduction of the sound which occurs when a vehicle passes

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))

Do not rely completely on the SCBS system:
 The SCBS 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.
