Rear Cross Traffic Alert (RCTA): When reversing from a parking space, RCTA detects and alerts the driver to any vehicle approaching from either side of the vehicle.
Lane-keep Assist System (LAS): Having detected a potential unintentional lane departure, the system will perform minor steering correction to safely place the vehicle back in the centre of the lane.
High Beam Control System (HBC): Automatically changes between high and low beam to help the driver quickly spot potential road hazards at night.
Smart City Brake Support (SCBS): Detects objects ahead at low speeds and prepares the vehicle to stop by adjusting the brake pads closer to the disc. If no driver action is taken, the system automatically applies the brakes.
Mazda Radar Cruise Control (MRCC): Monitors the speed of the vehicle ahead and automatically adjusts cruise control settings to maintain a safe headway distance.
Forward Obstruction Warning (FOW): Detects vehicles ahead and alerts the driver to an approaching risk of collision early enough for the driver to take evasive action.
Traffic Sign Recognition (TSR): Uses cameras to read road signs such as speed limit, do not enter, and stop signs. The colour Active Driving Display shows this information so the driver can stay informed without taking their eyes off the road.
Smart Brake Support (SBS): Assists in avoiding or reducing the severity of collisions at mid to high speeds by detecting vehicles and obstacles as far as 200 metres ahead. When a risk of collision is detected, the system slows the car automatically by applying the brakes.
