Before using the Audio and Visual system • In hot weather, cool the passenger compartment down before using the audio and visual system. The liquid crystal display operates correctly at temperatures between 0°C and 60°C (32°F and 140°F). When the temperature exceeds 60°C (140°F), the audio and visual system circuit protection function is activated, causing the display to dim. NOTE • In the interest of safety, the use of some functions may be unavailable while in driving. The buttons for a touch screen that cannot be used are displayed greyed out. • Liquid-crystal displays may be difficult to read when wearing polarized glasses. 108 Audio and Visual
