• If the ignition switch is turned to the OFF position while the FRE ( ) switch is set to ON (fresh air intake),
“Perform the memory” or “Do not perform the memory” of the FRE ( ) switch ON (fresh air intake) con-
dition can be selected.
• If “Perform the memory” was set, the FRE ( ) switch will be ON (fresh air intake) when turning the igni- tion switch to the ON position again.
• If “Do not perform the memory” was set, the air inlets will be controlled automatically when turning the igni- tion switch to the ON position again.
How to set
Using CONSULT, perform “FRE MEMORY SET” in “WORK SUPPORT” of HVAC.
NOTE:
When the battery cable is disconnected from the negative terminal or when the battery voltage becomes 10V or less, the setting of the
FRE switch memory function may be cancelled.

Description
• If the ignition switch is turned to the OFF position wh ile the REC ( ) switch is set to ON (recirculation),
“Perform the memory” or “Do not perform the memory” of the REC ( ) switch ON (recirculation) condi-
tion can be selected.
• If “Perform the memory” was set, the REC ( ) switch will be ON (recirculation) when turning the ignition
switch to the ON position again.
• If “Do not perform the memory” was set, the air inlets will be controlled automatically when turning the igni-
tion switch to the ON position again.
How to set
Using CONSULT, perform “REC MEMORY SET” in “WORK SUPPORT” of HVAC.
NOTE:
