Volvo XC90: Driver support / Cross Traffic Alert limitations

(* Option/accessory.)

(Warning for crossing traffic when the vehicle is backing up.)

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.

The function has certain limitations – the sensors, for example, cannot "see" through other parked vehicles or objects blocking the vehicle.

Below are a few examples of situations in which the function's field of vision may be initially limited and approaching vehicles may therefore not be detected until they are very close to your vehicle:

The vehicle is parked very far into a parking space.

In a diagonal parking space, Cross Traffic Alert may be completely "blind" on one side of your vehicle.

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.
  • CTA is automatically deactivated if a trailer, bicycle holder or similar is connected to the vehicle's electrical system.
  • For CTA to function effectively, bicycle holders, luggage racks or similar should not be mounted on the vehicle's towbar.

NOTE

The function uses the vehicle's radar sensors, which have certain general limitations.
