Cleaning the System The radar can become blocked by snow, ice or dirt. If so, you may need to turn off the engine and clean the lens. To clean the inside of the fascia lens and radar lens, insert a tool into one of the small slots on the inboard side of the lens and pop the lens out. Clean the surface with a 50/50 mixture of isopropyl alcohol and water on a dampened cloth. After cleaning the lens, set the lens back in place and press until it snaps in. Exterior Lamps The lens is located on the driver's side of the front fascia. Clean the surface with a 50/50 mixture of isopropyl alcohol and water on a dampened cloth. After cleaning the fascia lens, try to engage Adaptive Cruise Control. If this does not fix the problem, you may have to remove the fascia lens and clean the inside of the fascia lens and radar lens. The exterior lamp control is located to the left of the steering wheel on the multifunction lever. 164
