AIR CONDITIONER CONTROL
Revision: November 20092006 QX56
DISPLAY SCREEN
Displays the operational status of the system.
AUTO SWITCH
The compressor, intake door, air mix doors, outlet doors and blower speed are automatically controlled so
that the in-vehicle temperature will reach, and be maintained at the set temperature selected by the oper-
ator.
When pressing AUTO switch, air inlet, air outlet, blower speed, and discharge air temperature are auto-
matically controlled.
TEMPERATURE CONTROL DIAL (TEMPERATURE CONTROL) (DRIVER SIDE)
Increases or decreases the set temperature.
TEMPERATURE CONTROL DIAL (TEMPERATURE CONTROL) (PASSENGER SIDE)
Increases or decreases the set temperature.
TEMPERATURE CONTROL DIAL (TEMPERATURE AND MODE CONTROL) (REAR)
Increases or decreases the set temperature. The mode also changes from foot at full hot setting, to foot/vent
mid-range (warm) setting, and then to panel on full cold setting.
RECIRCULATION () SWITCH
When REC switch is ON, REC switch indicator turns ON, and air inlet is set to REC.
When REC switch is turned OFF, or when compressor is turned from ON to OFF, REC switch is automati-
cally turned OFF. REC mode can be re-entered by pressing REC switch again.
REC switch is not operated when DEF switch is turned ON, at the D/F position or in floor position.
DEFROSTER () SWITCH
Positions the air outlet doors to the defrost position. Also positions the intake doors to the outside air position.
REAR WINDOW DEFOGGER SWITCH
When switch is ON, rear window and door mirrors are defogged.
OFF SWITCH
The compressor and blower are OFF, the intake doors are set to the outside air position, and the air outlet
doors are set to the foot (75% foot and 25% defrost) position.
A/C SWITCH
The compressor is ON or OFF.
(Pressing the A/C switch when the AUTO switch is ON will turn off the A/C switch and compressor.)
MODE SWITCH (FRONT)
Controls the air discharge outlets.
FRONT BLOWER CONTROL DIAL
Manually control the blower speed. Seven speeds are available for manual control (as shown on the display
screen).

TURN SIGNAL AND HAZARD WARNING LAMPS
Revision: November 20092006 QX56
through door mirror LH and RH terminal 11
to grounds M57, M61 and M79 and
to rear turn signal lamp LH terminal 1
through rear turn signal lamp LH terminal 3
to grounds B7 and B19, and
to rear turn signal lamp RH terminal 4
through rear turn signal lamp RH terminal 6
to grounds B117 and B132.
BCM sends signal to combination meter through CAN communication lines, and turns on turn signal indicator
lamps within combination meter.
REMOTE KEYLESS ENTRY SYSTEM OPERATION
Power is supplied at all times
through 50A fusible link (letter f , located in the fuse and fusible link box)
to BCM terminal 70, and
through 10A fuse [No. 19, located in the fuse block (J/B)]
to combination meter terminal 8.
Ground is supplied
to BCM terminal 67 and
to combination meter terminal 17
through grounds M57, M61 and M79.
When the remote keyless entry system is triggered by input from the keyfob, the BCM, interpreting it as turn
signal is ON, outputs turn signal from BCM terminals 60 and 61.
The BCM supplies power
through BCM terminals 60 and 61
to front turn/fog lamp LH and RH terminal 2
through front turn/fog lamp LH and RH terminal 3
to grounds E9, E15 and E24, and
to door mirror LH and RH terminal 15
through door mirror LH and RH terminal 11
to grounds M57, M61 and M79 and
to rear turn signal lamp LH terminal 1
through rear turn signal lamp LH terminal 3
to grounds B7 and B19, and
to rear turn signal lamp RH terminal 4
through rear turn signal lamp RH terminal 6
to grounds B117 and B132.
BCM sends signal to combination meter through CAN communication lines, and turns on turn signal indicator
lamps within combination meter.
With power and input supplied, the BCM controls the flashing of the hazard warning lamps when keyfob is
used to activate the remote keyless entry system.
