Cross Traffic Alert(CTA) is a supplementary driver support system to BLISBlind Spot Information that is intended to help the driver detect vehicles crossing behind the vehicle while backing up.

P5-1507-CrossTrafficAlert Princip

CTA overview

CTA supplements BLIS by detecting traffic crossing from the side, e.g. when backing out of a parking space.

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.
