On some newer vehicles, you will see a TRAILER ANGLE INDICATOR icon in the upper-right corner of your screen when in Rear Trailer View while trailer guidelines are active. This icon is designed to help show you when your trailer may be in danger of jackknifing. When the icon swings to the amber/red-shaded area, you will receive a Jackknife Alert.
Jackknife Alert has two levels of alerting. When your vehicle first swings into the amber area on the Trailer Angle Indicator, you will see a yellow icon appear on your infotainment screen. You will also hear chimes or Safety Alert Seat vibrations, depending on your selected alert type preferences.
If you do not resolve the potential jackknifing situation and continue the manoeuvre, you will receive a second alert when entering the red-shaded area. This alert takes the form of a red icon on the infotainment system and chimes or Safety Alert Seat vibrations. When this alert occurs, you will also see your infotainment system display the Rear Camera View and, if equipped, a Top-Down View.
You can disable Jackknife Alert in your vehicle’s Settings menu.
Note: Jackknife Alert and Trailer Angle Indicator are only available on compatible trailers and require some setup in the in-Vehicle Trailering System. See your Owner’s Manual for detailed information.
