Cross Traffic Alert1*

Cross Traffic Alert(CTA) is a supplementary driver support system to BLIS2 that is intended to help the driver detect vehicles crossing behind the vehicle while backing up. The auto brake sub-function can help the driver stop the vehicle if there is a risk of a collision.

Examples of areas in which CTA can help the driver detect obstacles while backing up.

CTA is primarily designed to detect vehicles, but in certain cases can also detect pedestrians or smaller objects such as bicycles.

CTA is only active when the vehicle is moving backward or if reverse gear is engaged.

If CTA detects that something is approaching your vehicle from the side:
  • an audible signal will sound from either the left or right speaker, depending on which side of your vehicle the object is approaching from.
  • an icon will illuminate in the Park Assist System graphic on the screen.
  • an icon will appear in the Park Assist Camera's Top view.

If the driver does not pay attention to the warning from CTA and a collision is unavoidable, the auto brake function will intervene to stop the vehicle and a text will be shown on the instrument panel to explain why the vehicle was braked.
