The name MULTIFUNCTION SWITCH indicates the integration of PRESET SWITCH and MULTIFUNCTION SWITCH virtually.

Fail-Safe

When the ambiance temperature becomes extremely low or extremely high, or when HDD is malfunctioning, AV control unit displays the message and limits the AV control unit function.

FAIL‐SAFE CONDITIONS

When the ambiance temperature is −20°C (−4°F) or less, or when it is 70°C (158°F) or more
when HDD is malfunctioning

Display

The messages displayed on fail-safe conditions are as shown below:

Fail-safe mode	Display indication (fail-safe status display)
HDD at low temperature	The HDD does not operate when at a low temperature, and some functions cannot be used. These may return if the temperature increases
HDD at high temperature	The HDD does not operate when at a high temperature, and some functions cannot be used. These may return if the temperature decreases
When HDD is malfunctioning	A malfunction is detected on the HDD. Contact the dealer

DESCRIPTION OF CONTROLS

Function		When Fail‐safe Function is activated
Air conditioner	Operation	Only the operation of preset switch is possible.
Air conditioner	Display	Illumination of preset switch LED. Simplified indication of set temperature, wind direction, and air volume to the display.
Audio	Operation	Only ON/OFF of the audio system by preset switch and volume operation are possible.
Audio	Display	No display (“Fail-safe mode” is displayed).
Hands-free phone	Operation	It cannot be operated.
Navigation	Operation	It cannot be operated.
Multifunction meter	Operation	It cannot be operated.
Self diagnosis		The display indication is a simple indication of the fail-safe condition.
CONSULT-III diagnosis		It cannot be diagnosed.

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 fail-safe condition range, normal mode is restored.

When HDD is malfunctioning

If the malfunction disappears, normal mode is restored.
NOTE：

If fail‐safe mode due to HDD malfunction is seen continuously, replace AV control unit.
If fail‐safe mode due to HDD malfunction is seen temporarily, check the “Error History” of Confirmation/Adjustment mode. If this is normal, then continue the normal operation, observing the function. (It might be a temporary malfunction of HDD.)
