According to page 3-42 of your owners manual, "SBZA does not operate when the left or right corners of the rear bumper are covered with mud, dirt, snow, ice, slush, or in heavy rainstorms. For cleaning instructions, see Washing Your Vehicle on page 6‑98. If the DIC still displays the SIDE BLIND ZONE SYSTEM UNAVAILABLE message after cleaning the bumper, see your dealer."

Have you been receiving any SBZA error messages?
