Limitations of Cross Traffic Alert
The CTA1 function may have limitations in certain situations.
CTA does not perform optimally in all situations but has some limitations. For example, the CTA sensors cannot "see" through other parked vehicles or obstructing obstacles.
Here are some examples of situations where CTA’s "field of vision" may be already limited and approaching vehicles cannot therefore be detected until they are very close:
Blind CTA sector.
Sector in which CTA 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. See the supplementary information in the section "Recommended maintenance for Cross Traffic Alert".
- CTA is automatically deactivated if a trailer, bicycle rack or similar is connected to the car's electrical system.
- For optimal performance of CTA, no bicycle rack, luggage carrier or similar should be mounted on the car's towbar.
