The following new unit integrated blower, heater and
evaporator to increase the air flow, reduce noise, and
improved cooler and heater performance;:

｠

Integrated heater/cooling unit has been adopted for
large air flows and low noise.

｠

Crushable space has been secured to reduce the
risk of passenger injuries.

｠

Air mix damper that is also used as a reheating
prevention damper has been adopted to improve
the air cooling performance.

｠

The A/C condensate water outlet (drain port) has
been installed to behind the evaporator to restrain
the clogging of drain by foreign materials.

｠

The outlet air temperature of the defroster has been
set lower than that of foot to prevent overheating the
driver’s face.

｠

Fin thermo sensor to directly measure evaporator
temperature reduces occurrence risk of an
evaporator freeze which will lead to the compressor
lock.

｠

Clean air filter has been introduced as standard to
protect the unit from the intrusion of foreign
materials (fallen leaves and others). and, it removes
the pollen and dust, and improves the air quality
inside the passenger compartment.

｠

Clean air filter media and cover have been
separated to reduce the waste material amount
generated during the filter replacement.

｠

The installation position of clean air filter has been
set to the backside of glove box to facilitate the filter
replacement operation. And, the one-touch tab
structure has been adopted for the cover installation
to enable the replacement operation without tools.

The evaporator and heater core has been
longitudinally installed in the vehicle length, and the
crushable space has been adopted so that the
structure absorbs the impact in case of a collision and
reduces the risk of passenger injuries.

HEATER CONTROL

The features of the heater controller described below
have been designed for better appearance, easier
operation, and improved visibility.

｠

Each dial for the air outlet switching, fan volume
control, and temperature adjustment has been
enlarged to improve operability.

｠

Ring lights have been adopted to inside the dials to
improve appearance during nighttime.

｠

A confirmation sound at switch operation has been
added.

｠

AUTO and OFF positions of the fan volume control
dial have been exchenged with one another. This

change prevents the dial to pass the AUTO position
when the fan volume control is turned OFF, and
eliminates the necessity of manual reselection
when switching the inside/outside air selection
manually, thus improving the operability. <Vehicles
with automatic A/C>

｠

When the air outlet switching dial and fan volume
control dial are turned to the AUTO position, the A/
C switch has been made to automatically turn ON
to improve convenience. (Using the customize
function, this function can be cancelled.) <Vehicles
with automatic A/C>

A/C COMPRESSOR

ZC600338

Discharge cavity capacity

0000

High-efficiency scrolling compressor built into the oil separation
enhance the cooling performance. Compressor discharge cavity
capacity has been expanded to reduce discharge pulse,
vibration, and noise.

A/C COMPRESSOR CLUTCH WITH THERMAL

FUSE

A thermal fuse is installed in the A/C compressor field core. If
the compressor fails, the thermal fuse will be blown due to friction
heat produced by the drive belt and locked compressor. This
deenergizes the A/C compressor clutch and allows the
compressor to run freely.

A/C-ECU

CONTROL

FORCED DEF CONTROL
When air outlet position is switched to DEF, A/C is
automatically turned ON, and outside/inside air
selection damper is set to the fresh air position to
quickly defrost the windshield screen.

MAX A/C CONTROL <Vehicles with manual A/C>
When the preset temperature is set to the maximum
cooling, the control status becomes as described
below.

NOTE:

"*" indicates that when the automatic

function, the automatic control is not performed.

IDLE-UP CONTROL
A/C-ECU and the ECM communicate with each other
through the CAN communication. The idle-up speed
of the engine is controlled in two steps depending on
the A/C load to secure the air cooling performance
during summer and to improve fuel economy in
seasons with moderate temperature.

DETECTION CONTROL FOR REFRIGERANT
LEAKS
A/C-ECU determines if the refrigerant amount is less
than specified or refrigerant pressure is abnormal by
using the ambient temperature (ambient temperature
sensor to measure refrigerant inflation rate) and
refrigerant pressure (measured by the A/C pressure
sensor). When refrigerant amount or refrigerant
pressure is judged abnormal, the compressor is cut-
off to protect the A/C system.

NOTE:

When abnormality occurs, the A/C indicator

flashes.

REAR WINDOW DEFOGGER TIMER CONTROL
To reduce electrical load to battery, the defogger is
automatically turned OFF, 20 minutes after it is turned
ON or while engine is stopped.

PROTECTION CONTROL AT AIR BAG
DEPLOYMENT (DURING COLLISION)
When the air bag deployment is detected, the A/C
system is shut down.

CUSTOMIZE FUNCTION
Depending on the user's preference, the following
functions can be adjusted. The programmed
information is held even when the battery is
disconnected.

｠

Automatic control for inside/outside air selection
Press and hold (approximately for 10 seconds) the
inside/outside air selection switch to cancel the
automatic control for inside/outside air selection.

｠

A/C automatic control
Press and hold (approximately for 10 seconds) the
A/C switch to cancel the A/C automatic control.
