Temperature ControlINFOID:0000000009463201
• When the ignition switch is in the ON position, the cu stomer uses the front air control temperature control
dial to set the desired temperature.
• The front air control calculates the target front air mix door opening angle depending on the selected temper-
ature, intake temperature sensor, engine coolant temperature and rpm, and ambient temperature.
• Front air mix door is controlled depending on the comparison of current front air mix door opening angle and target front air mix door opening angle.
• Regardless of ambient temperature, the front air mix door is fixed at the fully cold position when the temper-
ature control dial is set at the full cold position and fi xed at the fully hot position when the temperature control
dial is set at the full hot position.

A/C switch Switches the compressor control switch indicator between ON
⇔ OFF with each press while front
blower fan is activated. The circuit used by the BCM to detect an A/C ON request is grounded.
NOTE:
When front blower fan is OFF, the compressor control cannot be activated.
Blower control dial (with
OFF switch) • Blower fan speed is manually controlled with the dial for varying blower speed. When ON, the circuit
used by the BCM to detect a fan ON request signal is grounded.
• Turns air conditioning system OFF.
NOTE:
When blower control dial is turned to any ON position the air conditioning system is activated. (Com-
pressor control state returns to the previous state before air conditioning system was turned OFF.)
DEF switch Switches DEF mode (switch indicator) between ON
⇔ OFF with each press.
• When DEF mode is turned ON, the air conditioning system changes to the following state.
- Air inlet: Fresh air intake
- Air outlet: DEF
- Blower fan: Manual setting.
- Compressor: ON
• When DEF mode is turned OFF, the air conditioning system state returns to the previous state be-
fore DEF mode was selected, but the following state is continued:
- Air inlet: Fresh air intake
- Compressor: ON
NOTE:
When front blower fan is OFF, DEF cannot be activated.

- Compressor: ON
NOTE:
When front blower fan is OFF, the compressor control cannot be activated.
MODE switches Selects air outlet from VENT, B/L, FOOT, and D/F.
NOTE:
When the air conditioning system is OFF, the air outlet can still be selected.
REC switch • Air inlet is selected to fresh air intake (REC) by pressing this switch.
- REC indicator: ON
NOTE:
• When the air conditioning system is OFF, the air inlet can still be selected.
• When D/F mode or DEF is selected, the REC button is disabled.
Temperature control dial • Selects desired temperature between full cold and full hot.
- Clockwise rotation: Temperature increases.
- Counterclockwise rotation: Temperature decreases.
