Maintenance of the Active Driving Display
The combiner and mirror surface have a special coating. When cleaning, do not use a hard or rough-surface cloth, or cleaning detergent. In addition, if a chemical solvent gets on the active driving display, wipe it off immediately. Otherwise, the combiner and mirror could be damaged and the surface coating could be scratched.
Use a fine, soft cloth such as those used for cleaning eyeglasses.
Cleaning the Lap/Shoulder Belt Webbing
Clean the webbing with a mild soap solution recommended for upholstery or carpets. Follow instructions. Do not bleach or dye the webbing; this may weaken it.
After cleaning the belts, thoroughly dry the belt webbing and make sure there is no remaining moisture before retracting them.
