Do not rely completely on the Smart City Brake Support (SCBS) system:
The Smart City Brake Support (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.
The Smart City Brake Support (SCBS) is a system which operates in response to a
vehicle ahead. The system may not be able to detect or react to 2-wheeled vehicles or
pedestrians.
The laser sensor for the Smart City Brake Support (SCBS) system is installed near the
rearview mirror. To assure the correct operation of the Smart City Brake Support
(SCBS), heed the following cautions.
Do not apply stickers to the surface of the windshield near the laser sensor
(including transparent stickers). Otherwise, the laser sensor may not be able to
detect vehicles or obstructions ahead which could result in an accident.
Do not disassemble the laser sensor.
If cracks or damage caused by fl ying gravel or debris is visible near the laser sensor,
stop using the Smart City Brake Support (SCBS) system immediately and have your
vehicle inspected by an Authorized Mazda Dealer. If the vehicle continues to be
driven with cracks or scratch marks left on the windshield near the laser sensor, the
system may operate unnecessarily and cause an unexpected accident.
Refer to Stopping The Smart City Brake Support (SCBS) System Operation on page
4-78 .
When replacing the windshield wipers or windshield, consult an Authorized Mazda
Dealer.
Do not modify the suspension:
If the vehicle height or inclination is changed, the system will not be able to correctly
detect vehicles or obstructions ahead. This will result in the Smart City Brake Support
(SCBS) system not operating normally or mistakenly operating, which could cause a
serious accident.
Turn off the Smart City Brake Support (SCBS) when the vehicle is running on a chassis
roller or being towed:
Turn off the Smart City Brake Support (SCBS) system to prevent mistaken operation when
the vehicle is running on a chassis roller or being towed. See the next page on how to turn
off the Smart City Brake Support (SCBS).
