Limitations of Blind Spot Information*
The Blind Spot Information (BLIS) function may have limitations in certain situations.
Examples of limitations:
- Dirt, ice and snow covering the sensors may reduce the functions and deactivate alerts.
- BLIS is deactivated when a trailer is connected to the car’s electrical system.
Sensors
The sensors for the BLIS function are located inside each corner of the rear wing/bumper. The sensors are also used by the Cross Traffic Alert (CTA) function.
To ensure optimal functionality, the areas in front of the sensors must be kept clean.
Do not affix any objects, tape or labels in the area of the sensors.
In some cases, the system detects that one or both sensors are blocked and then shows the message Blind spot sensor Rear sensors blocked, cleaning needed in the driver display - check and rectify as soon as possible.
Important
Repair of the BLIS and CTA functions' components or repainting the bumpers must only be performed by a workshop - an authorised Volvo workshop is recommended.
