Cross Traffic Alert*
CTA1 with auto brake 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 subfunction can stop the car in the event of a risk of collision with an unobserved vehicle.
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 PAS3 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.
Warning
- The Cross Traffic Alert function is supplementary driver support intended to facilitate driving and help make it safer – it cannot handle all situations in all traffic, weather and road conditions.
- The auto-brake subfunction can only detect and apply the brakes for other moving vehicles - not for e.g. stationary obstacles, cyclists or pedestrians.
- The responsibility for reversing the vehicle safely and using good judgment always rests with the driver.
- Cross Traffic Alert is not a substitute for the driver's attention and judgment. The driver is always responsible for ensuring the vehicle is driven in a safe manner, at the appropriate speed, with an appropriate distance to other vehicles, and in accordance with current traffic rules and regulations.
