NOTE
If you have set the lane departure warning sound to the beep sound/rumble sound *1
setting, the warning sound may not be heard depending on the surrounding noise
conditions.
If you have set the lane departure warning system to the steering wheel vibrations setting,
the vibration may not be felt depending on the road surface conditions.
When the setting for the steering operation assist is changed to operational, the warnings
can be set to activate/not activate. (When the setting for the steering operation assist is
changed to non-operational, the warnings cannot be set to not activate.)
Refer to Setting Change (Personalization Features) on page 9-11 .
The Lane-keep Assist System (LAS) & Lane Departure Warning System (LDWS) can be

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 specifi c
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
over a rumble strip.

*Some models.
Smart City Brake Support (SCBS) *
The Smart City Brake Support (SCBS) system is designed to reduce damage in the event
of a collision by operating the brake control (SCBS brake) when the system's laser sensor
(front) detects a vehicle ahead and determines that a collision with a vehicle ahead is
unavoidable. It may also be possible to avoid a collision if the relative speed between your
vehicle and a vehicle ahead is less than about 20 km/h (12 mph).
In addition, when the driver depresses the brake pedal while the system is in the operation
range at about 4 to 30 km/h (2 to 18 mph), the brakes are applied fi rmly and quickly to
assist. (Brake Assist (SCBS brake assist))
Laser sensor (front)
WARNING
Do not rely on the Smart City Brake Support System (SCBS) as a substitute for safer
driving:
The Smart City Brake Support (SCBS) system cannot compensate for unsafe and reckless
driving, excessive speed, tailgating (following another vehicle too closely), and driving on
slippery roads such as wet, snowy, and icy roads (reduced tire friction and road contact
because of water on the road surface). You can still have an accident.

When Driving
i-ACTIVSENSE
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 two-wheeled vehicles
or pedestrians.
The laser sensor (front) 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 (front)
(including transparent stickers). Otherwise, the laser sensor (front) may not be able
to detect vehicles ahead which could result in an accident.
Do not apply coating agent to the windshield. Otherwise, the laser sensor (front)
may not be able to detect vehicles or obstructions in front which could result in an
accident.
Do not disassemble the laser sensor (front).
If cracks or damage caused by fl ying gravel or debris is visible near the laser sensor
(front), 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
(front), the system may operate unnecessarily and cause an unexpected accident.
Refer to Stopping the Smart City Brake Support (SCBS) System Operation on page
4-132 .
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 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.
Refer to the Stopping the Smart City Brake Support (SCBS) System Operation on page
4-132 on how to turn off the Smart City Brake Support (SCBS) system.

When Driving
i-ACTIVSENSE
CAUTION
When driving off -road in areas where there is grass or foliage, it is recommended that the
Smart City Brake Support (SCBS) system be turned off .
Always use tires for all wheels that are of the specifi ed size, and the same manufacturer,
brand, and tread pattern. In addition, do not use tires with signifi cantly diff erent wear
patterns on the same vehicle as the Smart City Brake Support (SCBS) system may not
operate normally.
The laser sensor (front) includes a function for detecting a soiled windshield and informing
the driver, however, depending on the conditions, it may not detect plastic shopping bags,
ice or snow on the windshield. In such cases, the system cannot accurately determine a
vehicle ahead and may not be able to operate normally. Always drive carefully and pay
attention to the road ahead.
NOTE
The Smart City Brake Support (SCBS) system will not operate if the driver is deliberately
performing driving operations (accelerator pedal and steering wheel).
The Smart City Brake Support (SCBS) system will operate under the following conditions.
The engine is running.
“Forward Smart City Brake Support Malfunction” is not displayed in the multi-
information display.
The vehicle speed is between about 4 to 30 km/h (2 to 18 mph).
The Smart City Brake Support (SCBS) system is not turned off.
The DSC is not malfunctioning.
The Smart City Brake Support (SCBS) detects a vehicle ahead by emitting a near-infrared
laser beam and receiving the beam refl ected off the refl ector of the vehicle ahead, and
then using it for the measurement. Consequently, the Smart City Brake Support (SCBS)
may not operate under the following conditions:
Refl ection of the laser is poor due to the shape of the vehicle ahead.
The vehicle ahead is signifi cantly dirty.
Under bad weather condition, such as rain, fog and snow.
The window washer is being used or the windshield wipers are not used when it's
raining.
The windshield is dirty.
The steering wheel is turned completely left or right, or the vehicle is accelerated
rapidly and comes close to the vehicle ahead.
Trucks with low loading platforms and vehicles with an extremely low or high profi le.
Vehicles with certain shapes such as a vehicle carrier.

When driving on continuously curving roads, and entering and exiting exits.
Elongated luggage or cargo is loaded onto installed roof rails and covers the laser
sensor (front).
Exhaust gas from the vehicle in front, sand, snow, and water vapor rising from
manholes and grating, and water splashed into the air.
When towing a malfunctioning vehicle.
When driving with tires having signifi cantly different wear.
When the vehicle is driven in the following locations, the smart city brake support (SCBS)
may determine that there is a possibility of a collision and may operate.

Vehicles passing in the opposite lane while making a curve.
Metal objects, bumps, or protruding objects on the road.
When passing through a toll gate equipped with a bar.

When the vehicle is driven in the following locations with the inner/outer side of the near-
infrared laser irradiation part (black printed area in the center of the upper portion of the
windshield) fogged or covered in water droplets, the smart city brake support (SCBS) may
determine that there is a possibility of a collision and may operate.
The vehicle is driven into tunnels with low ceilings and on roads with structures above
the road such as road signs.
The vehicle is driven close to structures on the road such as road signs and guardrails.
When the system operates, the user is notifi ed by the multi-information display.
The Smart City Brake Support (SCBS) warning indication (amber) turns on when the
system has a malfunction.
