▼Stop Hold Control (Automatic
Transmission)
While in headway control using the CTS,
your vehicle will stop when a vehicle
ahead stops. When the vehicle is stopped
and the stop hold control operates, the
CTS indicator light turns on.
NOTE
If the CTS is temporarily canceled
during stop hold control, the vehicle is
held in its stopped position.
The parking brake is automatically
applied and the vehicle is held in its
stopped position when 10 minutes or
longer have passed since the stop hold
control operated. When this occurs, the
CTS is temporarily canceled.
The brake lights turn on during stop
hold control.

To resume driving
After the vehicle ahead starts moving
while your vehicle is stopped under stop
hold control, press the RE S switch or
depress the accelerator pedal to cancel the
stop hold control and start driving.
NOTE
When you resume driving by pressing
the RES switch, your vehicle does not
start moving until the distance between
your vehicle and the vehicle ahead
lengthens to the specified distance or
farther.
If the CTS is temporarily canceled,
depress the accelerator pedal and start
driving the vehicle. If the CTS is
temporarily canceled, you cannot
resume driving by pressing the RES
switch when there are no vehicles in
front of your vehicle.
If the vehicle ahead starts moving within
3 seconds after your vehicle is stopped
by the stop hold control, headway
control will continue even if you do not
resume driving your vehicle, such as by
depressing the accelerator pedal.

Vehicle departure information
If you do not resume driving within a few
seconds after the vehicle ahead starts
moving during stop hold control, the
multi-information display vehicle-ahead
indication flashes to urge the driver to
resume driving. If you do not resume
driving after the indicator light flashes, a
sound is activated to urge you to resume
driving.

Lane-keep Assist System(LAS)
*
▼Lane-keep Assist System (LAS)
The LAS provides steering assistance to
help the driver stay within the vehicle lane
if the vehicle might be deviating.
The forward sensing camera (FSC) detects
the white lines (ye
llow lines) of the
vehicle lane in which the vehicle is
traveling and if the system determines that
the vehicle may deviate from its lane, it
operates the electri c power steering to
assist the driver’s steering operation. The
system also alerts the driver by displaying
an alert on the mult i-information display
or the active driving display. Use the
system when you drive the vehicle on
roads with white (ye llow) lines such as
expressways and highways.
1. Forward sensing camera (FSC)
WA R N I N G

Smart Brake Support
(SBS)
*
▼Smart Brake Support (SBS)
The SBS alerts the driver of a possible
collision using the wa
rning indications in
the display and a warning sound if the
front radar sensor and Forward Sensing
Camera (FSC) determine that there is the
possibility of a collision with a vehicle
ahead, pedestrian, or a bicycle.
Furthermore, if 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 pe dal, the brakes are
applied firmly and quickly to assist.
(Vehicles with Driver Monitoring (DM))
When the SBS determines that the driver
is not paying attention to the road using
the driver monitoring camera and it
determines that there is the possibility of a
collision with an obs truction, the SBS
activates the collision warning earlier than
normal.
WA R N I N G
Do not rely completely on the SBS.
The SBS is only designed to reduce damage
in the event of a collision.
The ability to detect obstructions is limited
depending on the obstructions, weather
conditions, or traffic conditions. Over
reliance on the system leading to the
accelerator pedal or brake pedal being
mistakenly operated could result in an
accident.

Smart Brake Support[Rear] (SBS-R)
*
▼Smart Brake Support [Rear]
(SBS-R)
The SBS-R is a syste m which is designed
to reduce damage in the event of a
collision by operating the brake control
(SBS brake) when the system’s sensors
detect an obstruction at the rear of the
vehicle while driving at a speed of about 2
to 8 km/h (2 to 4 mph) and the system
determines that a collision is unavoidable.
WARNING
Do not rely completely on the SBS-R
system:
 The SBS-R 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.
 To assure the correct operation of the
SBS-R, heed the following cautions.
 Do not apply a sticker to a rear
ultrasonic sensor and rear camera.
Otherwise, the rear ultrasonic sensor
and rear camera may not be able to
detect vehicles or obstructions which
could result in an accident.
 Do not disassemble a rear ultrasonic
sensor and rear camera.
 If cracks or damage caused by flying
gravel or debris is visible around a rear
ultrasonic sensor and rear camera,
stop using the SBS-R 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
around an ultrasonic sensor, the
system may operate unnecessarily and
cause an unexpected accident.
Refer to Stopping the Smart Brake
Support [Rear] (SBS-R) System
Operation on page 4-159.
 Consult an Authorized Mazda Dealer
for rear bumper replacement.
Do not modify the suspension:
If the vehicle height or inclination is
changed, the SBS-R system may not
operate correctly because it cannot detect
obstructions correctly.
