- Dirt, ice and snow on the sensors may reduce functionality and prevent the system from providing warnings.
- Do not attach any objects, tape, decals, etc., on the surface of the sensors.
- BLIS is deactivated if a trailer is attached to the vehicle's electrical system.
Maintenance
The BLIS/CTA1 sensors are located on the inside of the rear fenders/bumper.
For the system to function optimally, the area over and around the sensors must be kept clean.
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.
