2021 MAZDA MODEL CX-9 brakes

Roads where frequent and repetitive accelerati on and deceleration occur (Driving under
these conditions using the MRCC with Stop & Go function system is not possible).
 When entering and exiting interchanges, servic e 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 (Tires could spin causing you to lose vehicle
control, or the stop hold control may not operate.)
 Long, descending slopes (to maintain distan ce between vehicles, the system automatically
and continuously applies the brakes which could result in the loss of brake power.)
 Slopes with a steep gradient (The vehicle ahea d may not be detected correctly, your vehicle
may slide while stopped by the stop hold control, and it may accelerate suddenly after it
starts moving.)
For safety purposes, switch the MRCC with Stop & Go function system off when it is not being
used.
Do not get out of the vehicle while the stop hold control is operating:
Getting out of the vehicle while the stop hold co ntrol is operating is dangerous as the vehicle
may move unexpectedly and result in an accident. Before getting out of the vehicle, switch the
MRCC with Stop & Go function system off, shift the selector lever to the P position, and apply
the parking brake.
CAUTION
If your vehicle is towed or you are towing something, switch the MRCC with Stop & Go
function system off to prevent a mis-operation.
NOTE
The MRCC with Stop & Go function system does not detect the following as physical
objects.
Vehicles approaching in the opposite direction
Pedestrians
Stationary objects (stopped vehicles, obstructions)
If a vehicle ahead is traveling at an extremely low speed, the system may not detect it
correctly.
During headway control travel, do not set the system for detection of two-wheeled
vehicles such as motorcycles and bicycles.
Do not use the MRCC with Stop & Go function system under conditions in which close
proximity warnings are frequently activated.

During headway control travel, the system accelerates and decelerates your vehicle in
conjunction with the speed of the vehicle ahead. However, if it is necessary to accelerate
for a lane change or if the vehicle ahead brakes suddenly causing you to close in on the
vehicle rapidly, accelerate using the accelerator pedal or decelerate using the brake
pedal depending on the conditions.
While the MRCC with Stop & Go function system is in use, it does not cancel even if the
selector lever is operated and any intended engine braking does not occur. If deceleration
is required, lower the set speed or depress the brake pedal.
The sound of the automatic brakes operating may be heard, however, it does not indicate
a problem.
The brake lights turn on while the MRCC with Stop & Go function automatic braking is
operating.

Advanced Smart City Brake Support (Advanced SCBS)*
The Advanced SCBS alerts the driver of a possible collision using the display and a warning
sound when the Forward Sensing Camera (FSC) detects a vehicle ahead or pedestrian and
determines that a collision with the object is unavoidable while the vehicle is driven at a
vehicle speed of about 4 to 80 km/h (2 to 50 mph) if the object is a vehicle ahead and about
10 to 80 km/h (6.2 to 50 mph) if the object is a pedestrian. In addition, the system reduces
damage in the event of a collision by operating the brake control (Advanced SCBS brake)
when the system determines that a collision is unavoidable. In addition, when the driver
depresses the brake pedal, the brakes are applied firmly and quickly to assist. (Brake Assist
(Advanced SCBS brake assist))

WARNING
Do not rely completely on the Advanced SCBS system:
 The Advanced 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 Advanced SCBS system operates in response to a vehicle ahead or a pedestrian. The
system does not operate in response to obstru ctions such as a wall, 2-wheeled vehicles, or
animals.

Smart City Brake Support [Forward] (SCBS F)*
The SCBS F system alerts the driver of a possible collision using an indication in the
display and a warning sound when the Forward Sensing Camera (FSC) detects 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 brake control (Smart City
Brake Support (SCBS) brake) when the system determines that a collision 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 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 (Smart City
Brake Support (SCBS) brake assist))

WA R N I N G
Do not rely completely on the SCBS F system:
 The SCBS F system is only designed to red uce damage in the event of a collision. Over
reliance on the system leading to the accel erator pedal or brake pedal being mistakenly
operated could result in an accident.
 The SCBS F 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.

Smart Brake Support(SBS)
*
The SBS system alerts the driver of a
possible collision us ing 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 sensor (front) and the Forward
Sensing Camera (FSC) determines that a
collision is unavoidable, the automatic
brake control is performed to reduce
damage in the event of a collision.
In addition, when the driver depresses the
brake pedal, the brakes are applied firmly
and quickly to assist. (Brake Assist (SBS
brake assist))
WARNING
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 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 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).
The relative speed between your
vehicle and the vehicle ahead is about
15 km/h or faster (10 mph or faster).
The Dynamic Stability Control (DSC)
is not operating.
The SBS system may not operate under
the following conditions:
If the vehicle is accelerated rapidly
and it comes close to a vehicle ahead.
The vehicle is driven at the same
speed as the vehicle ahead.
The accelerator pedal is depressed.
The brake pedal is depressed.
The steering wheel is being operated.
The selector lever is being operated.
