Forward Collision Warning System Performance Tips
Several factors affect the performance of the forward collision warning system (FCWS). Some conditions may prevent the FCWS feature from detecting a vehicle in front of you.
-
The FCWS feature activates only when your vehicle speed exceeds 65 km/h (40 mph).
-
The FCWS feature may not detect a vehicle in front of you when the camera's view of the vehicle is obscured by rain, fog, snow, sun or headlight glare, or darkness.
-
The FCWS feature may not function properly if the camera is incorrectly aligned (Setting the Camera Placement).
-
The FCWS feature may not detect vehicles farther away than 40 m (130 ft.) or closer than 5 m (16 ft.).
-
The FCWS feature may not function properly if the camera placement settings do not correctly indicate your vehicle height or the placement of your device in the vehicle (Setting the Camera Placement).
