They are SERVICE RADAR CRUISE, CRUISE NOT READY and CLEAN RADAR CRUISE. These messages will only appear to indicate a problem with the Adaptive Cruise Control. See DIC Warnings and Messages on page 3-60 for more information. You may also see CRUISE SPEED LIMITED displayed in the HUD. See Head-Up Display (HUD) on page 3-31 for more information. 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. 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 place.
