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.

ENVIRONMENTAL PROTECTION
M2000027000279
Mitsubishi has given careful consideration to protec-
tion of natural resources and the environment in the
vehicle. Environmentally friendly features are shown
below.
IMPROVEMENT ON RECYCLING EFFICIENCY
ClassificationMain Components
Components made
of recycled
materialsChip materials produced during manufacturing process has been reused as the
following components: Door inside handle, bu mper, radiator grille, instrument panel,
door trims, or floor padding.
Waste materials produced by other i ndustries have been reused as the following
components: Engine oil level gauge, air filter casing, and sound absorbing materials
for dash panel
Components made
of materials which
can be easily
recycledThermoplastic resin has been utilised as the following components: Inside door
handle, bumper, radiator grille, instrument panel, door trim
Thermoplastic resin has been utilised as t he following components: Vacuum hose for
engine control, air intake hose, hood weather strip, tailgate opening weather strip
REDUCTION OF MATERIAL BURDEN ON ENVIRONMENT
ItemMain Components
Elimination of
environmental
burden materialsLead-free materials have been utilised as the following components: Radiator, fuel
tank, power steering oil pressure hose, el ectrodeposition paint for body, glass ceramic
print, heater core, battery terminals, wiring harness
Non-asbestos material has been used for engine gaskets.
PVC(polyvinyl chloride)-free materials ha ve been used for the waterproofing film.
Prevention of
ozone depletionAir conditioner filled with new refrigerant (HFC 134a) has been installed.
Prevention of air
pollutionEmployment of a metal cylinder head gasket reduces the volume of incomplete
combustion generated between the cylinder block and cylinder head, and suppresses
the level of unburned hydrocarbon (HC).
SERVICEABILITY AND RELIABILITY

MULTI USE TESTER-III (M.U.T.-III) SUB
ASSEMBLY
Comprehensive improvements have been made to
the M.U.T.-II, a tester for diagnosing problems with
the electronic control system. For easier servicing,
the newly developed M.U.T.-III has greatly improved
functions and is much easier to use. The M.U.T.-III
expands the functions of the M.U.T.-II in the following
ways:
1.CAN* bus diagnosis
•Auto diagnosis function for the CAN commu-
nications bus line is added.
NOTE: *CAN: Controller Area Network (for further
details, refer to GROUP 54C
P.54C-2).

FUEL TANK
FUEL SUPPLY13C-4
•A resin coating is treated on the underfloor fuel
line pipes, improving reliability.
•A fuel tank pump with low power consumption
has been adopted to reduce the alternator load.
•A plastic tank pump and gauge assembly is used
to reduce weight.
•The fuel line tube and fuel line hose are made of
the material, which does not allow fuel vapour to
pass through it as much as possible, so that the
vapour gas emission to the air is reduced.
FUEL TANK
M2134001000442
The fuel tank assembly consists of components such
as a fuel tank pump and gauge assembly, a fuel
high-pressure hose, a fuel tank hose, and a fuel tank,
and has the following features:
•The fuel tank is located underneath the rear seats
to improve safety at a collision.
•The fuel tank itself is made of a pre-coat galva-
nized steel sheet that contains no lead.
•The fuel tank pump is housed in the fuel tank to
improve collision safety.
•A fuel tank safety valve, which prevents fuel leak-
age when the vehicle banks or rolls over, is
located inside the fuel tank pump and gauge
assembly.
•The fuel high-pressure hose and fuel tank hose
are made of the material, which does not allow
fuel vapour to pass through it as much as possi
-
ble.
The fuel tank pump and gauge assembly consist of
the following components:
•Fuel tank pump
•Fuel tank gauge unit
•Fuel tank filter assembly
•Fuel pump pressure regulator <4A9>
•Fuel tank safety valve
•Fuel tank 2-way valve
