System Operation

Forward Collision Alert 

The forward collision alert system is a convenience feature of the B174W Frontview Camera - Windshield 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 P16 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 P43 Collision Alert Indicators will flash. An audible alert sound will simultaneously sound. 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 B174W Frontview Camera - Windshield 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 B174W Frontview Camera - Windshield 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.

Forward Automatic Braking 

Forward automatic braking uses the B174W Frontview Camera - Windshield to determine if an imminent collision risk exists. If the brakes have not been applied, the system will automatically apply the brakes all the way to a complete stop in an effort to mitigate the collision or reduce collision damage. The system functions when driving in a forward gear between 8 km/h (5 mph) and 60 km/h (37 mph) and has a detection range of approximately 60 m (197 ft). Forward automatic braking will only function when a vehicle is detected, as indicated by the green vehicle ahead indicator is illuminated on the P16 Instrument Cluster.

Forward automatic braking 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 B174W Frontview Camera - Windshield 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 B174W Frontview Camera - Windshield area clean and in good repair.

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 B174W Frontview Camera - Windshield, 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.

Front Pedestrian Braking 

Front pedestrian braking uses the B174W Frontview Camera - Windshield to identify and help avoid or reduce the harm caused by front-end crashes with nearby pedestrians. When a pedestrian is detected, an amber pedestrian indicator is illuminated. When approaching a detected pedestrian too quickly, front pedestrian braking provides will flash the pedestrian indicator red and an audible alert sound will simultaneously sound or the safety alert seat will provide haptic feedback. Front pedestrian braking can provide a boost to braking via Intelligent brake assist or, if no action is taken by the driver, automatically brake the vehicle through forward automatic braking.

The front pedestrian braking system can detect and alert to pedestrians in a forward gear at speeds between 8 km/h (5 mph) and 80 km/h (50 mph). During daytime driving, the system detects pedestrians up to a distance of approximately 40 m (131 ft). During nighttime driving, system performance is very limited. Through vehicle personalization, front pedestrian braking can be set to Off, Alert, or Alert and Brake.
