Cross Traffic Alert (CTA)* limitations

CTA functionality may be reduced in certain situations.

Limitations

CTA has limitations in certain situations, for example, the CTA sensors cannot "see" through other parked vehicles or obstructions.

The following are several examples where CTA's "field of vision" may initially be limited and approaching vehicles cannot be detected until they are too close:

P5-1507-CrossTrafficAlert Princip-Exception1
The vehicle is pulled far into a parking space
P5-1507-CrossTrafficAlert Princip-Exception2
In angled parking spaces, CTA may be "blind" on one side
  1. P5-Icon red circle 1CTA's blind area
  2. P5-Icon red circle 2CTA's "field of vision"

However, as you back your vehicle out of a parking space, CTA's "field of vision" expands.

Examples of other limitations include:

  • Dirt, ice or snow obstructing the sensors may reduce the system's function or make it impossible to detect other vehicles or objects.
  • CTA is deactivated if a trailer's wiring is connected to the vehicle's electrical system.

Maintenance

The CTA sensors are located on the inside of the rear fenders/bumper.

P5-1646-S+V90-CrossTrafficAlert Sensor
Keep the highlighted area clean (on both sides of the vehicle) - generic illustration

For the system to function optimally, the area over and around the sensors must be kept clean.

Do not attach any objects, tape, decals, etc., on the surface of the sensors.

 Important

Repairs to the BLIS/CTA systems and/or repainting the rear bumper should only be done by a trained and qualified Volvo service technician.
