Limitations of Cross Traffic Alert*

The Cross Traffic Alert (CTA) function with auto-brake sub-function may have limited functionality in certain situations. Brake intervention is active at speeds below 15 km/h.

 Warning

The auto-brake sub-function can only detect and brake for other vehicles that are moving – not for stationary obstacles, a cyclist or a pedestrian, for example.

The function has a certain limitation – the sensors cannot "see" through other parked vehicles or obstructions, for example.

Here are some examples of situations where the function's "field of vision" may be already limited and approaching vehicles cannot therefore be detected until they are very close:

P5-1507-CrossTrafficAlert Princip-Exception1
The car is parked deep inside a parking slot.
P5-1507-CrossTrafficAlert Princip-Exception2
In an angled parking slot Cross Traffic Alert may be completely “blind” on one side.
  1. P5-Icon red circle 1Blind sector.
  2. P5-Icon red circle 2Sector in which the function can detect/"see".

However, as your car slowly reverses, the angle it makes with the obstructing vehicle/object changes and the blind sector rapidly decreases.

Examples of further limitations

  • Dirt, ice and snow covering the sensors may reduce the functions and deactivate alerts.
  • CTA is automatically deactivated if a trailer, bicycle rack or similar is connected to the car's electrical system.
  • For good performance of CTA, there should be no bicycle rack, luggage carrier or similar mounted on the car's towbar.

 Note

This function uses the car's radar units, which have certain general limitations.
