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:
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
- The auto-brake subfunction only detects moving vehicles and therefore cannot "see" and brake for stationary obstacles, a cyclist or a pedestrian, for example.
- 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.
