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:

P5-1507-CrossTrafficAlert Princip-Exception1
The vehicle is parked very far into a parking space.
P5-1507-CrossTrafficAlert Princip-Exception2
In a diagonal parking space, CTA may be completely "blind" on one side of your vehicle.
  1. P5-Icon red circle 1CTA's blind zone.
  2. P5-Icon red circle 2CTA'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 subfunction 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 sensors, which have certain general limitations.
  1. *Option/accessory.
  2. 1Warning for crossing traffic when the vehicle is backing up.
