Cross Traffic Alert*1 limitations
The Cross Traffic Alert (CTA) function with auto brake may have limited functionality in certain situations. Auto-brake is active at speeds under 15 km/h (9.3 mph).
Warning
The auto-brake sub-function can only detect and apply the brakes for other moving vehicles – not for e.g. stationary obstacles, cyclists or pedestrians.
CTA has certain limitations – The CTA sensors, for example, cannot "see" through other parked vehicles or objects blocking the vehicle.
Below are a few examples of situations in which CTA's field of vision may be initially limited and approaching vehicles may therefore not be detected until they are very close to your vehicle:
CTA's blind zone.
CTA's field of vision.
However, as you back your vehicle slowly out of a parking space, CTA's field of vision changes in relation to the obstructing vehicle/object and its blind zone is reduced.
Examples of further limitations
- The auto brake sub-function only detects vehicles in motion and may therefore not "see" and brake for e.g. stationary obstacles, a cyclists or a pedestrian.
- Dirt, ice and snow covering the sensors may reduce functionality and prevent the system from providing warnings.
Note
The function uses the vehicle's radar units, which have certain general limitations.
