NAVIGATION SYSTEM: BASIC FUNCTIONS Touch screen operation D Maintenance information This system informs about when to replace certain parts or components and shows dealer information (if registered) on the screen. When the vehicle reaches a previously set driving distance or date specified for a scheduled maintenance check, the "Information" screen will be displayed when the navigation system is in operation. This system is operated mainly by the touch screen buttons on the screen. To prevent damage to the screen, lightly touch buttons on the screen with the finger. When a button on the screen is touched, a beep sounds. (To set a beep sound, see page 298.) Do not use objects other than the finger to touch the screen. INFORMATION D If the system does not respond to a touch on a touch screen button, move the finger away from the screen and then touch it again. D Dimmed touch screen buttons cannot be operated. D Wipe off fingerprints using a glass cleaning cloth. Do not use chemical cleaners to clean the touch screen. D The displayed image may become darker and moving images may be slightly distorted when the display is cold. D Under extremely cold conditions, the map may not be displayed and the data input by a user may be deleted. Also, the touch screen buttons may be harder than usual to depress. D When you look at the screen through polarized material such as polarized sunglasses, the screen may be dark and hard to see. If so, look at the screen from different angles, adjust the screen settings on the "Display" screen, or take off your sunglasses. To disable this screen, touch "Do Not Display This Message Again". This screen goes off if the screen is not operated for several seconds. To prevent this information screen from being displayed again, touch "Do Not Display This Message Again".
