▼Camera and Sensors
Forward Sensing Camera (FSC)
The Forward Sensing Camera (FSC) detects lane indications and r
ecognizes headlights,
taillights and city lights during nighttime driving. In addition, it also detects the vehicle
ahead, pedestrians, or obstructions. The following systems also use the Forward Sensing
Camera (FSC).
High Beam Control system (HBC)
Lane-keep Assist System (LAS) & Lane Departure Warning System ( LDWS)
Traffic Sign Recognition System (TSR)
Smart City Brake Support (SCBS)
Smart Brake Support (SBS)
The Forward Sensing Camera (FSC) is installed at the top of the windshield near the
rearview mirror.
Refer to Forward Sensing Camera (FSC) on page 4-131.
Radar sensor (front)
The radar sensor (front) function s by detecting the radio waves reflected off a vehicle ahead
sent from the radar sensor. The following systems also use the radar sensor (front).
Mazda Radar Cruise Control (MRCC)
Distance Recognition Support System (DRSS)
Smart Brake Support (SBS)
The radar sensor (front) is moun ted behind the radiator grille.
Refer to Radar S ensor (Front) on page 4-136.

Slopes with a steep gradient ( The vehicle ahea d may not be detected correctly, your vehicle
may slide while stopped by the stop hold cont rol, and it may accelerate suddenly after it
starts moving.)
For safety purposes, switch the MRCC system off when it is not being used.
CAUTION
If your vehicle is towed or you are towing something, switch the MRCC system off to prevent a
miss-operation.
NOTE
The MRCC 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 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 system is in use, it does not cancel even if the selector lever (automatic
transaxle)/shift lever (manual transaxle) is operated and any intended engine braking will
not occur. If deceleration is required, lower the vehicle speed setting 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 automatic braking is operating.

▼ Close Proximity Warning
If your vehicle rapidly closes in
on the vehicle ahead because the vehicle ahead applies the
brakes suddenly while you are traveling in headway control, the warning sound activates
and the brake warning is indicated in the display. Always verif y the safety of the
surrounding area and depress the brake pedal while keeping a sa fer distance from the
vehicle ahead. Additionally, keep a safer distance from the veh icles behind you.
NOTE
In the following cases, the warnings and brakes may not operate even if your vehicle starts
closing in on the vehicle ahead.
You are driving your vehicle at the same speed as the vehicle ahead.
Directly after the MRCC system has been set.
Directly after the accelerator pedal is released.
Another vehicle cuts into the driving lane.
▼Setting the System
The MRCC system operates when all of the following conditions a
re met.
Vehicle speed is 30 km/h (19 mph) to 145 km/h (90 mph)
The MRCC is turned on.
The brake pedal is not depressed.
The parking brake is released (parking brake indicator light is turned off).

How to change the set vehicle speed
To accelerate/decelerate using the SET
switch
When you press the SET
switch, the
vehicle accelerates and when you press the
SET
switch, it decelerates.
Short press 1 km/h (1 mph)
Long press 10 km/h (5 mph)
NOTE
For example, the set vehicle speed is
changed by pressing the SET switch four
times as follows:
The vehicle speed accelerates or
decelerates by 4 km/h (4 mph).
To increase speed using accelerator
pedal
Depress the accelerator pedal and press
and release the SET
switch or SET
switch at the desired speed. If the switch is
not operated, the system returns to the set
speed after you release your foot from the
accelerator pedal.
CAUTION
The warnings and brake control do not
operate while the accelerator pedal is
depressed.
NOTE
When accelerating using the SET
switch while in headway control, the set
vehicle speed can be adjusted but
acceleration is not possible. If there is
no longer a vehicle ahead, acceleration
continues until reaching the set vehicle
speed. For the set vehicle speed, check
the set vehicle speed indication in the
display.
While depressing the accelerator pedal,
the color of the MRCC indication
changes from green to white.
Canceling the system
If any of the following operations is done,
the MRCC cancels temporarily, the
MRCC set indication (green) switches to
the MRCC main indication (white), and
the MRCC indicator light (green) turns off
at the same time.
The OFF/CAN switch is pressed.
The brake pedal is depressed.
The parking brake is applied.
(Automatic transaxle)
The selector lever i s in the P (Park), N
(Neutral), or R (R everse) position.
(Manual transaxle)
The shift lever is in the reverse (R)
position.
Any of the doors is opened.
The driver's seat belt is unfastened.

Under the following conditions, the
MRCC cancel indication is displayed in
the active driving display and a single
beep sound is heard.
The DSC has operated.
The Smart Brake Support (SBS) has
operated.
