*Some models.
Distance Recognition Support System (DRSS) *
The Distance Recognition Support System (DRSS) measures the distance between your
vehicle and a vehicle ahead using a radar sensor (front) while the veh\
icle speed is about
30 km/h (19 mph) or faster, and if your vehicle approaches a vehicle ahead more closely
than what is appropriate for maintaining distance between the vehicles a\
ccording to the
vehicle speed, a notifi cation in the active driving display is indicated to advise you to keep \
a
safe distance from the vehicle ahead.
WARNING
Do not rely completely on the Distance Recognition Support System (DRSS) and always
drive carefully: The Distance Recognition Support System (DRSS) provides advice for safer driving and
notifi es the driver of a recommended, safer distance to maintain with a vehicle ahead.
The ability to detect a vehicle ahead is limited depending on the type of vehicle ahead,
the weather conditions, and the traffi c 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 Distance Recognition Support System (DRSS) operates when all of th\
e following
conditions are met:
  The ignition is switched ON.  The Distance Recognition Support System (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 Distance Recognition Support System (DRSS) may also operate in the\
presence of
motorcycles and bicycles.
  The Distance Recognition Support System (DRSS) system 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 with Stop & Go function
(MRCC with Stop & Go function)
*
The Mazda Radar Cruise Control with Stop & Go function (MRCC with Stop & Go
function) 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 dis\
tance 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 ve\
hicle ahead detected by the Mazda Radar Cruise Control (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 suf fi cient distance between the vehicles.
If the vehicle ahead stops while you are following behind it, your vehic\
le will stop and be
held stopped automatically (stop hold control), and headway control wi\
ll resume when you
resume driving the vehicle such as by pressing the RES switch.
Also refer to the following before using the Mazda Radar Cruise Control \
with Stop & Go
function (MRCC with Stop & Go function).
   AUTOHOLD (page 4-75 )  Forward Sensing Camera (FSC) (page 4-156 )  Radar sensor (front) (page 4-162 )
WARNING
Do not rely completely on the Mazda Radar Cruise Control with Stop & Go function
(MRCC with Stop & Go function):
The Mazda Radar Cruise Control with Stop & Go function (MRCC with Stop & Go function)
system is designed to reduce load on the driver, and although it maintains a constant
vehicle speed, or specifi cally, it maintains a constant distance between your vehicle and
the detected vehicle ahead according to your vehicle speed, the 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
suffi ciently 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.

*Some models.
Smart Brake Support (SBS) *
The Smart Brake Support (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 ve\
hicle 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 i\
n the event of a
collision.
In addition, when the driver depresses the brake pedal, the brakes are a\
pplied fi rmly and
quickly to assist. (Brake Assist (SBS brake assist))
WARNING
Do not rely completely on the Smart Br ake Support (SBS) system and always drive
carefully: The Smart Brake Support (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 traffi c 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.
