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 accord\
ing to the vehicle
speed, a notification 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
notifies 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 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 Distance Recognition Support System (DRSS) operates when all of th\
e following
conditions are met:

*Some models.
Mazda Radar Cruise Control (MRCC)*
The Mazda Radar Cruise Control (MRCC) system is designed to maintain headway control*1
according to the vehicle speed using a radar sensor (front) to detect \
the distance to a vehicle
ahead, and by presetting the vehicle speed between 30 km/h (19 mph) an\
d 145 km/h (90 mph),
the driver is freed from having to constantly use the accelerator or bra\
ke 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 because, for ex\
ample, 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.
Use the Mazda Radar Cruise Control (MRCC) system on expressways and other highways
which do not require a lot of repeated acceleration and deceleration.
WARNING
Do not rely completely on the Mazda Radar Cruise Control (MRCC) system and always
drive carefully:
The Mazda Radar Cruise Control (MRCC) system is designed to reduce load on the driver,
and although it maintains a constant vehicle speed, or specifically, it maintains a constant
distance between your vehicle and the detected vehicle ahead according to the 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 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 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.
Do not use the Mazda Radar Cruise Control (MRCC) system in the following locations.
Otherwise, it could lead to an accident:
 Roads with sharp cur ves and where vehicle traffic is heavy and there is insufficient
space between vehicles. Roads where frequent and repetitive acceleration and
deceleration occur (Driving under these conditions using the Mazda Radar Cruise
Control (MRCC) system is not possible).
 When entering and exiting interchanges, service 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 (The tires could spin causing you to
lose vehicle control). Long descending slopes (to maintain distance between vehicles, the system automatically
and continuously applies the brakes which could result in the loss of brake power).
For the purposes of safety, switch the Mazda Radar Cruise Control (MRCC) system off
when it is not being used.

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 applied firmly and
quickly to assist. (Brake Assist (SBS brake assist))
WARNING
Do not rely completely on the Smart Brake 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 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.
