Active Safety System Operation

Forward Collision Alert 

The forward collision alert system is a convenience feature of the active safety control module, vehicle direction camera, radar sensor module - long range, radar sensor module - short range left front and radar sensor module - short range right front that issues a warning to the driver when a potential collision risk exists. When the system detects a vehicle in the path ahead, the green vehicle ahead indicator is illuminated on the instrument cluster. If the vehicle ahead is being followed too closely, the vehicle ahead indicator will be amber. When approaching another vehicle too rapidly, the collision alert symbol will flash in the head-up display. An audible alert sound will simultaneously sound or the safety alert seat will provide haptic feedback. The visual alert cannot be changed, but the driver can select between audible or haptic alerts in the vehicle personalization menus. Refer to the vehicle owner manual for more detailed information on vehicle personalization.

Forward collision alert does not provide a warning to help avoid a crash, unless it detects a vehicle. Forward collision alert may not detect a vehicle ahead if the vehicle direction camera is blocked by dirt, snow or ice or if the windshield is damaged. It may also not detect a vehicle on winding or hilly roads or in conditions that can limit visibility such as fog, rain or snow or if the headlamps or windshield are not cleaned or in proper condition. Keep the windshield, headlamps and vehicle direction camera area clean and in good repair.

Forward collision alert may provide unnecessary alerts for turning vehicles, vehicles in other lanes, objects that are not vehicles or shadows. These alerts are normal operation and the vehicle does not need service.

Intelligent Brake Assist 

Intelligent brake assist is designed to pre-fill the brake hydraulic system to reduce system response time and increase pressure when quickly applying the brakes. Using the active safety control module, vehicle direction camera, radar sensor module - long range, radar sensor module - short range left front and radar sensor module - short range right front, the system monitors the approach speed and distance to a vehicle ahead. If the Intelligent brake assist system determines a collision risk exists, it will begin preparations to the brake hydraulic system. When active, minor brake pedal pulsations or pedal movement may occur and this should be considered normal. Intelligent brake assist will resort to normal braking operation after an intelligent brake assist even has occurred when the brake pedal is released.

Automatic Collision Preparation 

Automatic collision preparation system uses the active safety control module, vehicle direction camera, radar sensor module - long range, radar sensor module - short range left front and radar sensor module - short range right front to determine if an imminent collision risk exists. If the brakes have not been applied, the system will automatically apply the brakes in an effort to mitigate the collision or reduce collision damage. The system has a detection range of approximately 60 m (197 ft) and will only function when a vehicle is detected, as indicated by the green vehicle ahead indicator is illuminated on the instrument cluster.

Automatic collision preparation is not a substitute for normal vehicle braking and should not be relied on to brake the vehicle. Automatic collision preparation may not detect a vehicle ahead if the vehicle direction camera is blocked by dirt, snow or ice or if the windshield is damaged. It may also not detect a vehicle on winding or hilly roads or in conditions that can limit visibility such as fog, rain or snow or if the headlamps or windshield are not cleaned or in proper condition. Keep the windshield, headlamps and vehicle direction camera area clean and in good repair.

Backing Warning System 

The backing warning system utilized the active safety control module, radar sensor module - short range left rear, radar sensor module - short range right rear and the front and rear parking assist control module to warn of rear objects when backing up at speeds greater than 8 km/h (5 mph). Utilizing the ultrasonic rear object sensors, the front and rear parking assist control module can only detect object at seeps up to 8 km/h (5 mph). By utilizing the active safety control module and radar sensor modules - short range along with the front and rear parking assist control module and the rear object sensors, object can be detected at speeds greater than 8 km/h (5 mph).

While reversing at speeds greater than 8 km/h (5 mph), the backing warning system will alert the driver with an audible alert or through haptic feedback from the safety alert seat when an object is first detected. If the system detects a potential collision risk, a series of audible beeps or haptic feedback pulses will be provided, as well as a quick pulse of the brakes.

Rear Automatic Braking 

The rear automatic braking system is designed to help avoid or reduce the harm caused by backing crashes. If the system detects the vehicle is backing too fast to avoid a collision, it may automatically brake hard to a stop.

Utilizing the active safety control module, radar sensor module - short range left rear, radar sensor module - short range right rear and the front and rear parking assist control module, rear automatic braking attempts to avoid imminent collision by automatically braking the vehicle when traveling in reverse. In conjunction with the backing warning system, if the driver does not respond to the audible and haptic alerts while reversing, the system will automatically brake the vehicle to a stop.

Rear automatic braking also prevents the vehicle from backing into an object if the vehicle is stopped and shifted to R. If the system detects an object immediately behind the vehicle while attempting to reverse from a stop, the brakes will be applied.

Pressing the brake pedal after the vehicle comes to a stop will release the rear automatic braking. It may be necessary to release the electronic parking brake. When it is safe to do so, pressing the accelerator pedal firmly at any time will override the rear automatic braking. If rear automatic braking is active and there is no object behind the vehicle, make sure there is no snow, ice or debris on the rear object sensors.

Lane Departure Warning 

The lane departure warning system is a convenience feature that utilizes the vehicle direction camera and active safety control module to determine if the vehicle has unintentionally crossed a lane marking and issue a warning. The vehicle direction camera is located behind the windshield, looking out at the road ahead and detecting any lane markings. When the vehicle unintentionally leaves a detected lane, visual and audible or haptic alerts are given to the driver. The visual alert cannot be changed, but the driver can select between audible or haptic alerts in the vehicle personalization menus.

Refer to Lane Departure Warning Description and Operation (without UGN)  and/or Lane Departure Warning Description and Operation (UGN)  for more information about the Lane Departure Warning function.
