If equipped, Trailer Side Blind Zone Alert is a trailering feature that can provide outside rearview alerts when a moving vehicle is detected in a side blind zone that is extended to trailer lengths when towing a trailer. It can help you avoid lane change collisions.
Trailer Side Blind Zone Alert can detect vehicles a short distance behind the end of the trailer the vehicle is towing.
You will receive an alert icon on the side mirror when the feature detects a vehicle in the trailer side blind zone.
To turn Trailer Side Blind Zone Alert on, enable Lane Change Alert† through the Settings menu when a trailer is attached to the vehicle. When a trailer is attached, the regular Lane Change Alert with Side Blind Zone Alert feature is disabled and only Trailer Side Blind Zone Alert can be used.
Trailer Side Blind Zone Alert will be active when the vehicle is out of PARK (or the parking brake is off on manual transmission vehicles) and you have a trailer attached. The feature is disabled when a trailer is not attached.
When a trailer is no longer attached, Lane Change Alert with Side Blind Zone Alert will revert to the previous on or off setting as soon as the trailer is unattached.
The feature supports trailers of different lengths depending on the vehicle. You can input trailer length as part of a trailer profile in the Trailering App†. This can improve vehicle detection and avoid false alerts.
