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 ahead of you.
-
The FCWS feature activates only when your vehicle speed exceeds 50 km/h (30 mph).
-
The FCWS feature may not detect a vehicle ahead 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 (Aligning the camera).
-
The FCWS feature may not detect vehicles greater than 40 m (130 ft.) away 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 (Aligning the camera).
