Interior features
■When using the Remote Touch screen
●If the screen is cold, the display may be dark, or the system may seem to be operat-
ing slightly slower than normal.
●When the screen is viewed through polarized sunglasses, a rainbow pattern may
appear on the screen due to optical characteristics of the screen. If this is disturb-
ing, please operate the screen without polarized sunglasses.
●Dimmed screen buttons cannot be operated.
■Changing between day mode and night mode
The display condition is not changed to night mode even if the headlight switch is
turned on when the vehicle is in a bright area such as daytime.
■To t u r n o f f t h e d i s p l a y
The display goes off when “Screen Off” is selected. To turn the “Display” screen back
on, select any button. The selected screen appears. To display the screen in day mode, even with
the headlight switch on, select “Day Mode”
for brightness and contrast control.
If the screen is set to day mode with the
headlight switch turned on, this condition is
memorized even with the hybrid system
turned off.
NOTICE
■To avoid damaging the Remote Touch screen
Wipe off fingerprints using a glass cleaning cloth. Do not use chemical cleaners to
clean the screen, as they may damage the Remote Touch screen.
