PRE-COLLISION SYSTEM
When the millimetre-wave radar and monocular camera detect a collision with a vehicle ahead is likely, it alerts the driver using a buzzer and on the multi-information display, and activates pre-crash brake assist when the driver depresses the brake pedal. If the driver cannot depress the brake pedal, then it activates the pre-crash brakes to help avoid a collision or mitigate the impact force.
Dynamic Radar Cruise Control
In addition to maintaining a constant speed, Dynamic Radar Cruise Control uses the millimeter-wave radar and monocular camera to detect a vehicle driving ahead and maintain an appropriate distance between vehicles at speeds over 40km/h.
LTA (LANE Tracing ASSIST) and AHS (ADAPTIVE HIGH-BEAM SYSTEM)
LTA with Steering Control alerts the driver with a sensory alert using steering wheel vibration or a buzzer, and on the multi-information display if the system judges the vehicle is about to cross the lane markings without using the turn signals, and assists steering to avoid lane departure. In addition, Vehicle Sway Warning monitors steering operation and the vehicle’s position within a lane to detect vehicle sway due to driver inattention or drowsiness, and alerts the driver by a buzzer and on the multi-information display. AHS helps safe driving at night by instantly switching from high to low beam when the lights of an oncoming vehicle, or the tail lights of a vehicle in front, are detected.
RCTA (Rear Cross Traffic Alert)
To assist safe reversing, RCTA uses quasi-millimeter-wave radars in the rear bumper to detect approaching vehicles in difficult-to-see areas behind the vehicle. When an approaching vehicle is detected, RCTA alerts the driver using a buzzer and indicator in the relevant door mirror.
