Pre-collision assist depends on the detection ability of its camera and sensors. Any obstructions or damage to these areas can limit detection or prevent the system from functioning. See
Locating the Pre-Collision Assist Sensors.
The system is active at
3 mph (5 km/h) and above.
Note:
The pre-collision assist system disables when you select four-wheel drive low or manually disable AdvanceTrac™.
Note:
Brake support and automatic emergency braking are active at speeds up to
80 mph (130 km/h). If the vehicle has a radar sensor included with adaptive cruise control, then brake support and automatic emergency braking are active up to the maximum speed of the vehicle.
Pedestrian Detection Limitations
Pedestrian detection is active at speeds up to
50 mph (80 km/h).
Pedestrian detection functions optimally when detected hazards are clearly identifiable. System performance may reduce in situations where pedestrians are running, partly obscured, have a complex background, or cannot be distinguished from a group.
