DOOR MIRROR
M2510008100154
The door mirror is a folded type and has the following
characteristics.
•Features an electric retractable remote controlled
mirror.
•Vehicle speed-dependent automatic return func-
tion.
•A vertically-enlarged mirror has been used for
easy confirmation of safety around the vehicle.
•Aerodynamic door mirror shape have been devel-
oped so that the door glasses and mirrors do not
easily get wet with raindrops while driving in a
rainy day.
•Flag type door mirror shape which secures suffi-
cient distance between the door mirror and delta
pillar has been adopted to reduce the blind spot
area of the forward view.

GENERAL INFORMATION
HEATER, AIR CONDITIONER AND VENTILATION55-2
GENERAL INFORMATION
M2551000100759
For the heater and A/C system, the heater, the
blower and the cooling unit are integrated as one unit
to reduce weight and size. For A/C system, the man
-
ual A/C has been adopted.
FEATURES
IMPROVEMENTS IN COMFORT
•Adoption of low noise, large air volume heater
and A/C system
•Adoption of smaller air intake box for larger pas-
senger leg space.
•Optimising the areas of the outside air induction
hole and the air outlet improves ventilation per
-
formance as well as the quietness of the room
•Adoption of clean air filter with deodorant function
for cleaner air in the compartment.
IMPROVEMENTS IN OPERATION
PERFORMANCE
•Inside/outside air selection switch has been
changed to a pushbutton switch.
•Improved operation ability by the enlarged tab on
the dial knob
•Air amount and temperature only are controlled
automatically for easier operation. automatic A/C>
RELIABLE VISUAL FIELD
(IMPROVEMENT IN SAFETY)
•Current type defroster nozzle has been adopted
to improve defogging performance (Shortens
windshield fogging time).
•Defroster vents have been integrated to secure
better defogging pattern.
•Black coin drop prevention ribs are used on the
defroster to prevent its reflection on the wind
-
shield, providing sufficient field of vision for safety
IMPROVEMENTS IN FUEL ECONOMY
•Wider condenser area reduces load to the A/C
and improves fuel consumption.
•Energy conservation control using outside air
temperature sensor is adopted for vehicles with
manual A/C as well.
•A small-size, highly-efficient compressor has
been adopted.
•Simpler wiring and weight reduction are achieved
by installation of CAN communication system
GLOBAL ENVIRONMENT PROTECTION
Adoption of HFC134a for refrigerant.
IMPROVEMENTS IN SERVICE QUALITY
•Reduction of refrigerant gas leakage and
improvement in serviceability by incorporating
condenser and receiver
•The layout of refrigerant line for better workability
is adopted.
RESPONSIBILITY IMPROVEMENT
Reliable information transmission is achieved by
connecting A/C-ECU and each ECU via CAN com
-
munication.

control functions.

AUTOMATIC CHANGE CONTROL OF
BLOW WIND TEMPERATURE
(COMPRESSOR
ENERGY-CONSERVATION CONTROL)
Optimum ON/OFF control of the compressor is
achieved according to the outside/inside air mode,
air temperature (air temperature sensor), and insula
-
tion.
OUTSIDE/INSIDE AIR AUTO SWITCHING
CONTROL
When the A/C is turned on in high ambient tempera-
ture, the recirculation function is automatically acti-
vated to cool down the passenger compartment and
improve fuel consumption.
COOLING FUN LOAD CONTROL
Depending on the A/C load, the cooling fan cycle
time is controlled and the exterior noise in the inter
-
mediary stage is decreased. Also, the load of the
alternator is decreased to improve the fuel economy.
COOLING CONTROL
If air temperature is high, the CVT rotates at a high
speed to prevent deterioration in cooling perform
-
ance.
DETECTION CONTROL FOR
REFRIGERANT LEAKS
When it is judged from the air temperature (air tem-
perature sensor) and the refrigerant pressure (A/C
pressure sensor) that the refrigerant amount is the
specified value or less, or the refrigerant pressure is
abnormal, the compressor is forced to be cut off to
protect the A/C system.
MAX A/C CONTROL AUTOMATIC A/C>
When MAX COOL position is set, automatically the
mode is changed to the inside air mode before the
A/C is turned ON, thereby facilitating the operation
for obtaining maximum cooling performance.
ESTIMATION CONTROL FOR
COMPRESSOR TORQUE
Communication between the engine⋅CVT-ECU and
A/C-ECU is made to control the engine according to
the compressor torque for higher drivability and
reduction in fuel consumption.
FORCIBLE DEFROSTER CONTROL

When the defroster vents are selected, the A/C is
automatically turned ON. At this time, the out
-
side/inside air selection damper is operated to the
fresh-air position to defrost the windshield glass
quickly.
