i-ACTIVSENSE
i-ACTIVSENSE is a collective term covering a series of advanced safety and driver support
systems which make use of a Forward Sensing Camera (FSC) and radar sensors. These
systems consist of active safety and pre-crash safety systems.
These systems are designed to assist the driver in safer drivin g by reducing the load on the
driver and helping to avert collisions or reduce their severity . However, because each system
has its limitations, always drive carefully and do not rely sol ely on the systems.

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 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 ar e not operated correctly it could lead to an
accident. Always verify the safety of the su rrounding 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 travelling 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)
â–¼Indication on Display
The DRSS operation status is indi
cated in the active driving display or multi-information
display. Regarding malfunctions, check the vehicle conditions o r have it inspected by an
expert repairer, we recommend an Authorised Mazda Repairer acco rding to the content of
the displayed message.

Mazda Radar Cruise Control (MRCC) (Manual Transaxleand Taiwan)
*
The MRCC system is designed to maintain headway control*1 with a vehicle ahead
according to your vehic le'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 s tarts 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 4-201)
WA R N I N G
Do not rely completely on the MRCC:
The MRCC system has detection limitations depe nding 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 hittin g 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 repetitive accelerati on 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 a ccelerate to the set speed).
 Slippery roads such as ice or snow-bound roads (Tyres could spin causing you to lose
vehicle control, or the stop hold control may not operate.)
