Temperature Setting Trimmer (Front)

INFOID:0000000009652540

DESCRIPTION

If the temperature felt by the customer is different from the front air flow temperature controlled by the temper-
ature setting, the A/C auto amp. control temperature can be adjusted to compensate for the temperature set-
ting.

HOW TO SET

1.

Starts on board self-diagnosis STEP 5 mode (Each sensor recognition temperature check; “51” or “52” is
indicated on front A/C control display).

2.

Press fan switch (up:  +) and check that “61” is indicated on front A/C control display.

3.

After approximately 3 seconds, the temperature setting trimmer (front) can be available.

4.

The indication will be changed by “5” (“1”) in range of 

−

3.0

°

C (

°

F) to +3.0

°

C (6

°

F) by pressing the tem-

perature control switch (driver side) each time. Press temperature control switch (driver side) ( ) to
increase the set temperature, and press temperature control switch (driver side) ( ) to decrease the set
temperature. When balance setting is minus, A/C switch indicator is turned ON.

Inlet Port Memory Function

INFOID:0000000009652543

DESCRIPTION

• Air inlet is memorized when ignition switch is turned OFF, and the air inlet can be set either REC (recircula-

tion), FRE (fresh air intake), or “Do not perform the memory” when ignition switch is turned ON again.

• When “Do not perform the memory” is set, the air inlet is controlled automatically when ignition switch is

turned ON again. 

HOW TO SET

1.

Starts on board self-diagnosis STEP 5 mode (Each sensor recognition temperature check; “51” or “52” is
indicated on front A/C control display).

2.

Press fan switch (up:  +) and check that “61” is indicated on front A/C control display.
