For the system to function optimally, the area
over and around the sensors must be kept clean.
Do not attach any objects, tape, decals, etc., on
the surface of the sensors.
CAUTION
Repairs to the BLIS/CTA systems and/or
repainting the rear bumper should only be
done by a trained and qualified Volvo service
