P5-1646-S+V90-CrossTrafficAlert Sensor
Keep the surface clean - on both the left and right-hand sides of the car1.

The sensors for BLIS are located inside each corner of the rear wing/bumper. The sensors are also used by the Cross Traffic Alert (CTA) 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.
