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 driving 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 solely on the systems.
Pre-crash safety technology is designed to assist the driver in averting collisions or reduce their severity in situations where they cannot be avoided.
Collision damage reduction in low vehicle speed range
Forward driving
Collision damage reduction in medium/high speed range
Forward Sensing Camera (FSC)
The Forward Sensing Camera (FSC) detects lane indications and recognizes headlights, taillights and city lights during nighttime driving. The following systems also use the Forward Sensing Camera (FSC).
High Beam Control system (HBC)
Lane Departure Warning System (LDWS)
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) (Search).
Radar sensor (front)
The radar sensor (front) functions 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 mounted behind the radiator grille.
Refer to Radar Sensor (Front) (Search).
Laser sensor (front)
The laser sensor (front) emits a near-infrared laser beam and receives the beam reflected off the reflective surface of a vehicle in front, and the detected beam is then used for measurement. The following systems also use the laser sensor (front).
Smart City Brake Support (SCBS)
Smart Brake Support (SBS)
The laser sensor (front) is installed at the top of the windshield near the rearview mirror.
Refer to Laser Sensor (Front) (Search).
Radar sensors (rear)
The radar sensors (rear) function by detecting the radio waves reflected off a vehicle approaching from the rear or an obstruction sent from the radar sensors. The following systems also use the radar sensors (rear).
Blind Spot Monitoring (BSM) System
Rear Cross Traffic Alert (RCTA)
The radar sensors (rear) are installed inside the rear bumper, one each on the left and right sides.
Refer to Radar Sensors (Rear) (Search).
The Distance Recognition Support System (DRSS) measures the distance between your vehicle and a vehicle ahead using a radar sensor (front) while the vehicle speed is 30 km/h or faster (19 mph or faster), and indicates a recommended distance to maintain between the vehicles. Furthermore, if your vehicle approaches a vehicle ahead more closely than the appropriate distance to maintain between the vehicles, the vehicle-ahead indication in the multi-information display is flashed to advise the driver to keep a safer distance from the vehicle ahead.
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.
The Distance Recognition Support System (DRSS) operates when all of the 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) 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)
The Distance Recognition Support System (DRSS) operation status is displayed in the multi-information display in the instrument cluster.
Problems are indicated in the center display (Type B audio). If there is a problem, take appropriate action according to the displayed message.
Refer to Warning/Indicator Lights (Search).
When the ignition is switched off, the operation status before the system was turned off is maintained. For example, if the ignition is switched off with the Distance Recognition Support System (DRSS) operable, the system will be operable when the ignition is switched ON the next time.
The Distance Recognition Support System (DRSS) can be turned on/off and the system's sensitivity can be changed using the INFO button on the steering switch.
Refer to Personalization Features (Search).
