5) Shutting-off Condition of the A/C Compressor
Coolant temperature ▶
When coolant temperature is below 20°C or over 115°C, engine speed is below 650 rpm or
over 4500 rpm for 4 seconds after engine starting, abrupt acceleration and A/C refrigerant
pressure sensor detecting the followings
A/C compressor is turned off when the refrigerant pressure is below 2.0 kg/cm2 and then
is turned on when the refrigerant pressure is over 2.4 kg/cm2.
A/C compressor is turned off when the refrigerant pressure is over 30 kg/cm2 and then is
turned on when the refrigerant pressure is below 21.4 kg/cm2. -

3. WARNING LIGHTS AND INDICATORS
ESP OFF Indicator
This lamp comes on when pressing
the "ESP OFF" switch or the ESP
system is defective. When the ESP
system is activated, this lamp blinks
and a chime sounds.
Immobilizer Indicator
This indicator comes on when the
ignition key is communicating with
the engine control unit for approx.
0.5 seconds.
Glow Indicator
When the ignition key is turned ON,
this indicator lamp comes on and the
combustion chamber is warmed up.
In the vehicle equipped with direct
injection type engine, this indicator
may come on very shortly or may not
come on.
Fog Lamp / Headlamp
High Beam Indicator
This lamp comes on when
the fog lamp or high beam
headlamp operates to
indicate the operating
status.Engine Oil Pressure Warning Ligh
This lamp comes on if there is any
fault in the engine oil system and
goes off when a certain amount of
time has elapsed after turning ON
the ignition switch.
Door ajar warning
light
This light comes on
when a door or
tailgate is either
opened or not
closed completely.Brake warning light
This warning light comes on
and warning buzzer sounds
when the parking brake is
applied and/or the brake fluid
level is lower than specified
level.Seat belt warning lamp
The seat belt warning light comes on
and the seat belt warning chime
sounds for 6 seconds when the
ignition switch is turned to "ON"
position unless the driver's seat belt is
securely fastened. This reminding
operation stops when the driver
fastens the seat belt.
Engine Coolant Overheat
Warning Light
When the coolant temperature is
abnormally hot (over 120℃), this
warning light blinks and a
warning buzzer sounds at 1 Hz.
(check cooling system)

2) Function of N Switch
(1) Aids a smooth start of the vehicle by raising the RPM during the gear
shifting when the engine is cold.
When the vehicle is trying to start from the stopped state (vehicle speed below 3 km/h), the N
switch determines the shifting timing by using the clutch switch and the N switch. It raises the
engine RPM (100 ~ 200 rpm). Operation conditions are as follows.
The vehicle speed is at the stopped state (Vehicle speed below 3km/h detection).
While depressing the clutch (Clutch switch detection).
The gear lever is at a position other than neutral (N switch detection).
Start the vehicle while depressing the clutch pedal (Clutch switch detection).
The RPM increases in accordance with the temperature of the engine coolant
(Engine coolant temperature sensor detection). -

When the gear has been smoothly shifted and the vehicle speed exceeds 3km/h, it returns to
the previous operation interval of the engine RPM. -
In case of Actyon, the N switch signal is transmitted to the instrument panel, and then the
instrument panel transmits it to the engine ECU through the CAN communication.

5. A/C INPUT/OUTPUT DIAGRAM
Below diagram shows the input/output mapping between the components of FATC A/C and A/C
controller briefly.
▶ A/C compressor control by engine ECU
In case of current vehicle models, the system turns ON or OFF the compressor switch according
to the refrigerant pressure, ambient temperature and condenser temperature to protect the
A/C
circuits. However, for the vehicles equipped with DI engine, the engine ECU turns off the
A/C
compressor under below conditions, including those above.
Coolant temperature: 20℃ or less
Coolant temperature: 115℃ or more
For approx. 4 sec. after starting the engine
Engine speed: 650 rpm or less
Engine speed: 4,500 rpm or more
During abrupt acceleration for the vehicle equipped with manual transmission 1.
