▼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)

Distance Recognition Support System (DRSS)*
The DRSS measures the distance between your vehicle and a vehicle ahead using a radar
sensor (front) while the vehicle speed is about 30 km/h (19 mph ) or faster, and if your
vehicle approaches a vehicle ahead more closely than what is ap propriate for maintaining
distance between the vehicles according to the vehicle speed, a notification in the active
driving display is indicated to advise you to keep a safe dista nce from the vehicle ahead.
WA R N I N G
Do not rely completely on the DRSS and always drive carefully:
The ability to detect a vehicle ahead is limite d depending on the type of vehicle ahead, the
weather conditions, and the traffic conditions. Therefore, if the accelerator and brake pedals
are not operated correctly it could lead to 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.
NOTE
The DRSS operates when all of the following conditions are met:
The ignition is switched ON.
The DRSS is on.
The selector lever is in a position other than reverse (R).
The vehicle speed is 30 km/h or faster (19 mph or faster).
The objects which activate the system are 4-wheeled vehicles.
The DRSS may also operate in the presence of motorcycles and bicycles.
The DRSS may not operate normally under the following conditions:
The Dynamic Stability Control (DSC) has a malfunction.
The vehicle ahead is traveling at an extremely slow speed.
The system does not operate with the following objects:
Vehicles approaching in the opposite direction.
Stationary objects (stopped vehicles, obstructions)

Mazda Radar Cruise Control (MRCC)*
The MRCC system is designed to maintain headway control*1 with a vehicle ahead
according to your vehicle's speed using a radar sensor (front) to detect the distance to the
vehicle ahead and a preset vehicle speed without you having to use the accelerator or brake
pedals.
*1 Headway Control: Control of the distance between your vehicle and the vehicle ahead
detected by the MRCC system.
Additionally, if your vehicle starts closing in on the vehicle ahead such as if 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.
Also refer to the following before using the MRCC.
Radar sensor (front) (page 4-136)
WA R N I N G
Do not rely completely on the MRCC:
The MRCC 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 drive carefully and verify the surrounding conditions and depress the brake pedal or
accelerator pedal while keeping a safer distance from vehicles ahead or on-coming vehicles.
Do not use the MRCC system in the following locations, using the MRCC system at the
following locations may result in an unexpected accident:
 General roads other than highways (Driving under these conditions using the MRCC system
is not possible.)
 Roads with sharp curves and where vehicle tr affic is heavy and there is insufficient space
between vehicles.
 Roads where frequent and repeti tive acceleration and deceleration occur (Driving under
these conditions using the MRCC 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 sp in 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.)

When traveling on a downslope for a
long period of time.
There is a problem with the system.
The radar sensor (front) cannot detect
target objects (during rain, fog, snow or
other inclement weather conditions, or
when the radiator grille is dirty).
The vehicle speed decreases to less than
25 km (16 mph).
(Manual transaxle)
The shift lever is shifted to neutral (N)
for a certain period of time.
The clutch is depressed for a certain

The engine stalls.
Resuming control
If the MRCC system is canceled, you can
resume control at the previously set speed
by pressing the RES switch and after all of
the operation conditions have been met.
NOTE
If the set speed is not indicated in the
display, the control does not resume even
if the RES switch is pressed.
Turning off the system
Press the OFF/CAN switch two times
while the MRCC system is operating to
switch off the system.

Smart Brake Support (SBS)*
The SBS system alerts the driver of a possible collision using 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 se nsor (front) and the Forward
Sensing Camera (FSC) determines that a collision is unavoidable , the automatic brake
control is performed to reduce da mage in the event of a collision.
In addition, whe n the driver depresses the brake ped al, the brakes are applied firmly and
quickly to assist. (Brake Assist (SBS brake assist))
WA R N I N G
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 de pending 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.
