Keep the surface clean - on both the left and right-hand sides of the car1.

The sensors for CTA are located inside each corner of the rear wing/bumper. The sensors are also used by the BLIS2 and Rear Collision Warning functions.


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.
