When the light switch is in the 1st or 2nd position, the dimming of the display is judged according to a dimming
signal transmitted from BCM to the AV control unit. Dis play illuminance is independent of vehicle exterior illu-
minance detected by the auto light detecting sensor ev en when the light switch is in 1st or 2nd position.
MULTI AV SYSTEM : Fail-SafeINFOID:0000000006216217
When the ambiance temperature becomes extremely low or extremely high, AV control unit displays the mes-
sage and limits the AV control unit function.
FAIL-SAFE CONDITIONS
When the ambiance temperature is −20 °C ( −4 °F) or lower, or when it is 70 °C (158 °F) or higher

The messages displayed on fail-safe conditions are as shown below:
DESCRIPTION OF CONTROLS
Ability Operation Mode
There is an ability operation mode for Fail-safes due to low or high ambiance temperature.
If HDD data can be read, fail-safe is shown, then normal displays are displayed only for functions which can be
operated.
RELEASE CONDITIONS OF FAIL-SAFE
Fail-safe is released on following conditions and normal mode is restored.
When The Temperature of HDD Is Low or High
If the ambient temperature becomes out of fa il-safe condition range, normal mode is restored.
Fail-safe mode Display (display of the fail-safe condition)

justment
When there is a difference between the actual turning angle and the ve-
hicle mark turning angle, it can be adjusted.
Speed Calibration When there is a difference between the current location mark and the ac-
tual location, it can be adjusted.
