Forward Pedestrian Braking (FPB)
If equipped, the Forward Pedestrian Braking (FPB) system may help avoid or reduce harm caused by front-end crashes with pedestrians in the vicinity when driving in forward gear. FPB displays an amber indicator,
, when a pedestrian is detected directly ahead. If the vehicle approaches a detected pedestrian too quickly, FPB displays a flashing red warning on the windshield and sounds a rapid audible alert. FPB can increase braking effectiveness or automatically brake the vehicle. This system includes Intelligent Brake Assist (IBA) and Forward Automatic Braking (FAB) can also respond to pedestrians. Refer to Forward Automatic Braking (FAB).
The FPB system can detect and alert for pedestrians ahead when driving at speeds between 8 km/h and 80 km/h. In daytime, the system detects pedestrians at a distance of approximately 40 m (131 ft). During nighttime driving, system performance is very limited.
- When a pedestrian is not directly ahead, fully visible, standing upright, or is part of a group.
- Due to poor visibility, including nighttime conditions, fog, rain, or snow.
- If the FPB sensor is blocked by dirt, snow, or ice.
- If the headlights or windshield are not clean or in proper condition.
Be prepared to act and apply the brakes. For additional information, refer to Safe Driving. Keep the windshield, headlights, and FPB sensor clean and in good repair.
For FPB, the setting can be changed to Off, Alert, or Alert and Brake through Vehicle Personalization. Refer to "Collision/Detection Systems" in Vehicle Personalization.
Forward Pedestrian Detection

FPB warnings and automatic braking will not occur if the FPB system detects a pedestrian. When a pedestrian is detected directly in front of the vehicle, the forward pedestrian indicator will display amber.
Forward Pedestrian Alert

When the vehicle approaches a pedestrian ahead too quickly, the FPB red warning display will flash on the windshield. Eight rapid high-pitched beeps will sound. When this pedestrian warning occurs, the brake system may prepare for braking by the driver faster, which may cause a brief light deceleration. Continue to press the brake pedal as needed. Cruise control may be disengaged when the forward pedestrian alert occurs.
Automatic Braking
If FPB detects that a collision with a pedestrian directly ahead is imminent and the brakes have not been applied, FPB may automatically apply moderate or heavy braking. This may help avoid or reduce the severity of a low-speed pedestrian collision. FPB may automatically brake for detected pedestrians between 8 km/h and 80 km/h. Automatic braking levels may be reduced under certain conditions, such as higher speeds.
If this occurs, automatic braking may apply the Electric Parking Brake (EPB) to hold the vehicle at a stop. Release the EPB. A firm press of the accelerator pedal will also release automatic braking and the EPB.
Automatic braking can be turned off through Vehicle Personalization. See "Forward Pedestrian Detection" in "Collision Detection Systems" in Vehicle Personalization.
Cleaning the System
If FPB does not appear to operate correctly, cleaning the outside of the windshield in front of the rearview mirror may resolve the problem.
