BSM OFF Indicator Light
This indicator light illuminates for a few
seconds when the ignition is switched ON.
The BSM OFF indicator light illuminates
when the BSM system is turned off by
pressing the BSM OFF switch.
The indicator light flashes if the BSM
system has a malfunction. Consult an
Authorized Mazda Dealer.
NOTE
If the vehicle is driven on a road with less
traffic and few vehicles that the radar
sensors can detect, the system may pause
(The BSM OFF indicator light in the
instrument cluster flashes). However, it
does not indicate a malfunction.
BSM OFF Switch
When the BSM OFF switch is pressed, the
Blind Spot Monitoring (BSM) and Rear
Cross Traffic Alert (RCTA) systems are
turned off and the BSM OFF Indicator
Light in the instrument cluster turns on.
If the switch is pressed again, the Blind
Spot Monitoring (BSM) and Rear Cross
Traffic Alert (RCTA) systems become
operable and the BSM OFF Indicator
Light turns off.
NOTE
 When the ignition is switched off, the
condition before the system was turned
off is maintained. For example, if the
ignition is switched OFF while the
Blind Spot Monitoring (BSM) and Rear
Cross Traffic Alert (RCTA) systems are
operational, the Blind Spot Monitoring
(BSM) and Rear Cross Traffic Alert
(RCTA) systems remain operational the
next time the ignition is switched ON.
 The Blind Spot Monitoring (BSM) and
Rear Cross Traffic Alert (RCTA) systems
are turned off when the battery is
disconnected such as when the battery
terminals or fuses have been removed
and re-installed. To turn the Blind Spot
Monitoring (BSM) and Rear Cross
Traffic Alert (RCTA) systems back on,
press the BSM OFF switch.

Forward Obstruction Warning (FOW)
Forward Obstruction Warning (FOW) is a system which alerts the driver of a possible
collision using an indicator and warning sound in the instrument cluster\
while the vehicle
is being driven at about 15 km/h or faster (10 mph or faster) and the \
system's radar sensor
determines that your vehicle may hit a vehicle or obstruction ahead.
WARNING
Do not rely completely on the Forward Obstruction Warning (FOW) system and always
drive carefully:Forward Obstruction Warning (FOW) is only designed to reduce damage in the event of
a collision. 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 safe
distance from vehicles ahead or on-coming vehicles.
NOTE
 The Forwar d Obstruction Warning (FOW) system operates when all of the following
conditions are met:
 The ignition is switched ON. The Forward Obstruction Warning (FOW) system is on. The vehicle speed is about 15 km/h (10 mph) or faster . The relative speed between your vehicle and the vehicle or obstruction ahead \
is about
15 km/h (10 mph) or faster.
 The Forward Obstruction Warning (FOW) system may not operate under the following
conditions:
 If there is the possibility of hitting only a part of a vehicle or obstruction \
ahead. If the vehicle is accelerated rapidly and it comes close to a vehicle ah\
ead. The DSC is malfunctioning. The vehicle is driven at the same speed as the vehicle ahead. The accelerator pedal is depr essed. The brake pedal is depressed. The steering wheel is being operated. The selector lever is being operated. The turn signal is being used.

Mazda Radar Cruise Control (MRCC)
The Mazda Radar Cruise Control (MRCC) system is designed to maintain headway control*1
according to the vehicle speed using a radar sensor (front) to detect \
the distance to a vehicle
ahead, and by presetting the vehicle speed between 30 km/h (19 mph) an\
d 145 km/h (90
mph), the driver is freed from having to constantly use the accelerator\
or brake pedals.
*1 Headway Control: Control of the distance between your vehicle and the ve\
hicle ahead
detected by the Mazda Radar Cruise Control (MRCC) system.
Additionally, if your vehicle starts closing in on the vehicle ahead because, for ex\
ample, the
vehicle ahead brakes suddenly, a warning sound and a warning indication in the display are
activated simultaneously to alert you to maintain a sufficient distance between the vehicles.
Use the Mazda Radar Cruise Control (MRCC) system on expressways and other highways
which do not require a lot of repeated acceleration and deceleration.
WARNING
Do not rely completely on the Mazda Radar Cruise Control (MRCC) system and always
drive carefully: The Mazda Radar Cruise Control (MRCC) system is designed to reduce load on the
driver, and although it maintains a constant vehicle speed, or specifically, it maintains
a constant distance between your vehicle and the detected vehicle ahead according to
the vehicle speed, the system has detection limitations depending on the type of vehicle
ahead and its conditions, the weather conditions, and the road conditions. Additionally,
the system may be unable to decelerate sufficiently to avoid hitting the vehicle ahead
if the vehicle ahead applies the brakes suddenly or another vehicle cuts into the driving
lane, which 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.
Do not use the Mazda Radar Cruise Control (MRCC) system in the following locations.
Otherwise, it could lead to an accident:
 Roads with sharp cur ves and where vehicle traffic is heavy and there is insufficient
space between vehicles. Roads where frequent and repetitive acceleration and
deceleration occur (Driving under these conditions using the Mazda Radar Cruise
Control (MRCC) system is not possible).
 When entering and exiting interchanges, service areas, and parking areas of highways
(If you exit a highway while headway control is in use, the vehicle ahead will no longer
be tracked and your vehicle may accelerate to the set speed).
 Slippery roads such as ice or snow-bound roads (The tires could spin causing you to
lose vehicle control). Long descending slopes (to maintain distance between vehicles, the system
automatically and continuously applies the brakes which could result in the loss of
brake power).

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 relativ\
e speed between your
vehicle and a vehicle ahead is less than about 15 km/h (9.3 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 firmly and quickly to
assist. (Brake Assist (SCBS brake assist))
Laser sensor
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.

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 (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 flying 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
4-110. 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. See the next page on how to turn
off the Smart City Brake Support (SCBS).

CAUTION
 When driving off-road in areas where there is grass or forage, it is recommended that the
Smart City Brake Support (SCBS) system be turned off. Always use tires for all wheels that are of the specified size, and the same manufacturer,
brand, and tread pattern. In addition, do not use tires with significantly different 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.

 The Smart City Brake Support (SCBS) detects a vehicle ahead by emittin\
g a near-infrared
laser beam and receiving the beam reflected off the reflector 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:
 Reflection of the laser is poor due to the shape of the vehicle ahead. The vehicle ahead is significantly dirty. Under bad weather condition, such as rain, fog and snow . The window washer is being used or the windshield wipers ar e 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 profile. Vehicles with certain shapes such as a vehicle carrier.
