BLIS and CTA - symbols and messages

Updated 7/23/2018

In situations where the BLIS (Blind Spot Information System) and CTA functions fail or are interrupted, the combined instrument panel may show a symbol, supplemented by an explanatory message. Follow any recommendation given.

Message examples:




CTA has been deactivated manually. BLIS is active.

BLIS and CTA OFF Trailer attached

BLIS and CTA are temporarily disabled because a trailer is connected to the car’s electrical system.

BLIS and CTA Service required

BLIS and CTA are not working.

  • Visit a workshop if the message remains - an authorised Volvo workshop is recommended.

A text message can be acknowledged by briefly pressing the OK button on the direction indicator stalk.
