GENERAL DESCRIPTION
HEATER, AIR CONDITIONING AND VENTILATION55-2
GENERAL DESCRIPTIONM2551001500040
The blower, heater, and evaporator have been inte-
grated with the heater and A/C system to achieve a
greater fan power and noise reduction.
FEATURES
.
ENHANCEMENTS IN COMFORT
•With the adoption of fully-automatic A/C, the out-
side/inside air circulation switching, air outlet, and
outlet air temperature are automatically con
-
trolled according to the ambient temperature,
solar radiation, and passenger compartment tem
-
perature so that the optimum air conditioner is
achieved.
•By the adoption of clean air filter, the air quality
inside the passenger compartment has been
enhanced.
.
ENHANCEMENTS IN OPERATION
PERFORMANCE
•Operability has been enhanced by the adoption
of large triple dial.
•Customise function has been added for the
enhanced convenience.
.
ENHANCEMENTS IN FUEL ECONOMY
•The high efficiency compressor with a 2-step pro-
file oil separator has been installed, thus enhanc-
ing the fuel economy.
•The idle-up speed is controlled in two steps to
secure the air cooling performance during sum
-
mer and to enhance the fuel economy in the sea-
sons with moderate temperature.
•Enhancement of fuel economy by the cooling fan
control depending on the refrigerant pressure and
vehicle speed.
.
ENHANCEMENT IN SAFETY
•A/C system is stopped when the air bags are
deployed.
•Crushable space has been adopted to heater unit
to reduce the risk of passenger injuries in case of
a collision.
.
GLOBAL ENVIRONMENT PROTECTION
•New refrigerant system (HFC134a) has been
adopted.
•By the optimisation of A/C system, the refrigerant
charging amount has been reduced.
•Clean air filter media and its cover are separated
to reduce waste materials.
.
ENHANCEMENTS IN SERVICE QUALITY
•Reduction of refrigerant gas leakage and
enhancement in serviceability by incorporating
condenser and receiver
•Clean air filter is installed to the backside of glove
box to facilitate the filter replacement.
.
ENHANCEMENTS IN RESPONSIBILITY
Reliable information transmission is achieved by
connecting A/C-ECU and each ECU via CAN com
-
munication.

HEATER CONTROLLER
.
The features of the heater controller described below
have been designed for better appearance, easier
operation, and enhanced visibility.
•Each dial for the air outlet switching, fan volume
control, and temperature adjustment has been
enlarged to enhance operability.
•Ring lights have been adopted to inside the dials
to enhance appearance during nighttime.
-
cles with automatic A/C>
•AUTO and OFF positions of the fan volume con-
trol 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 enhancing the operabil
-
ity.
•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 enhance convenience. (Using the custom
-
ize function, this function can be cancelled. Refer
to
P.55-7.)
