NOTE
While in EV mode, acceleration may be restricted and the vehicle may not be able
to be driven at the set speed.
Refer to Mazda intelligent Drive Select (Mi-Drive) on page 5-95.
If there is a structure on the road or an obstruction at a low height off the ground
in front of the vehicle, the system may recognize it as a vehicle ahead.
Acceleration and deceleration by accelerator pedal operation takes priority while
traveling at a constant speed or in headway control. When the accelerator pedal is
released, the vehicle returns to driving at a constant speed or headway control at
the set speed.
The Forward Sensing Camera (FSC) may not be able to detect target objects
correctly, and the CTS may not operate normally.
Refer to Forward Sensing Camera (FSC) on page 5-127.
If a vehicle ahead is traveling at an extremely low speed, the system may not
detect it correctly.
While driving using the CTS, intended engine braking is not applied even if the
selector lever is operated.
The brake lights turn on while the brakes are operating by the CTS control.

Smart Brake Support(SBS)
*
SBS is a system designed to avoid
collisions and reduce damage in the
event of a collision by controlling the
brakes. Sensors and camera equipped
on the vehicle detect objects, and
operate brake control if there is a
possibility of your vehicle colliding with
the object.
One part of the SBS functions when
you are driving forward and the other
part functions when you are driving in
reverse.
Forward drive detection
Forward drive detection has the
following 4 functions.
Forward detection function
*
The forward detection function is
designed to assist the driver in avoiding
collisions with objects (vehicles ahead,
pedestrians, bicycles, and motorcycles)
at the front and to reduce damage in
the event of a collision.
If there is a possibility of your vehicle
colliding with a target object at the
front, you are notified of possible
danger by a screen display and a
warning sound. Furthermore, if the
possibility of a collision increases,
brake control is performed to avoid
collision and 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.
Tu r n -A c ro s s Tra ffi c*
The Turn-Across Traffic is designed to
assist the driver in avoiding a collision
with a vehicle approaching in the
opposite direction when making a left
turn at an intersection and to reduce
damage in the event of a collision.
If there is a possibility of your vehicle
colliding with a vehicle approaching in
the opposite direction when you make
a left turn at an intersection, you are
notified of possible danger by a screen
display and a warning sound.
Furthermore, if the possibility of a
collision increases, brake control is
performed to avoid collision and
reduce damage in the event of a
collision.

Refer to Cameras on page 5-137.
Always check the surrounding area
visually.
The operation of the SBS has certain
limitations. Always confirm the safety
around the vehicle visually when
driving.
CAUTION
 If any of the following conditions is
met, turn the SBS
off to prevent a
mis-operation.
 A trailer is pulled or an accessory
such as a bicycle carrier is installed
to the rear of the vehicle.
 The vehicle is driven on rough
roads such as in areas where there
is grass and foliage or off-road.
 Always use tires of the specified size
and the same manufacturer, brand,
and tread pattern on all 4 wheels. In
addition, do not use tires with
significantly different wear patterns
on the same vehicle. If such
improper tires are used, the SBS may
not operate normally.
How to Use the Smart
Brake Support (SBS)
NOTE
During the SBS brake control, the
brake pedal may move rearward or
become stiff. The brakes are operating,
but continue to depress the brake
pedal.
When the forward detection function
operates*
The forward detection function
operates when all of the following
conditions are met.
(If an object is a vehicle ahead)
The vehicle speed is about 4 km/h
(3 mph) or faster.
(If an object is a bicycle/pedestrian)
The vehicle speed is about 10
km/h to 80 km/h (6.3 mph to 49
mph).
The DSC does not operate.The system determines that there is a
possibility of a collision with an
object ahead.
When the forward detection function
operates, the driver is notified of the
danger by the screen display and
warning sound. Furthermore, if the
possibility of a collision increases,
brake control is performed.

Secondary CollisionReduction
*
The Secondary Collision Reduction
reduces secondary damage by
decelerating the vehicle when it is
damaged in a collision to the extent
that the airbags are deployed while
driving.
If a collision occurs to the extent that
the airbags are deployed while driving,
the hazard warning lights flash to alert
surrounding vehicles and the brakes
are controlled to reduce damage in the
event of a collision with an obstruction
or other object.
Warnings and Cautions
for Using the Secondary Collision Reduction
WARNING
Do not rely completely on the
Secondary Collision Reduction.
The Secondary Collision Reduction
may not operate normally depending
on various conditions such as the
accident condition, component part
damage condition, target object
condition, weather conditions, or
traffic conditions. Do not rely
completely on the system and make
it your responsibility as a driver to
drive the vehicle.
 The functions of the Secondary
Collision Reduction have limitations.
If you neglect to operate the brake
and accelerator pedals correctly, it
could result in serious injury.

How to Use the
Secondary Collision Reduction
When the Secondary Collision
Reduction operates
The Secondary Collision Reduction
operates if the vehicle is damaged in a
collision to the extent that the airbags
are deployed while driving.

When the Secondary Collision
Reduction operates, the system
controls and applies the brakes until
the vehicle stops. In addition, the
hazard warning lights continue to flash.
After the vehicle stops, the parking
brake is applied by the Electric Parking
Brake (EPB).
NOTE
The brake lights turn on while the
brakes are operating by the system
control.
If there is a malfunction with the
electric parking brake (EPB), the
brakes are released by the system
control after the vehicle is stopped.
The settings for the Secondary
Collision Reduction system differ
depending on the grade/specification-separate equipment.
Secondary Collision Reduction is
disabled
If any of the following conditions is
met, the Second ary Collision
Reduction is canceled.
A certain period of time has passed
since the system operated.
After stopping the vehicle, the
accelerator pedal is strongly
depressed 3 times.
The parking brake is released after
the Electric Parking Brake (EPB)
operates.
NOTE
If the driver's brake pedal depression
force is stronger than the system's
brake control, the driver's brake
operation takes priority.
Flashing of the hazard warning lights
by the system control is canceled
when any of the following operations
is performed.
Hazard warning light switch is
pressed.
Vehicle power is switched OFF.
