GENERAL DESCRIPTION CONCERNING THE INTERIOR LAMPM1549021800236
Refer to circuit diagrams GROUP-90
Refer to configuration diagrams GROUP-80The following ECUs affect the functions and control
of the interior lamps.
Interior lamp control function
The ETACS-ECU controls the interior lamps by turn-
ing them on and off in the following way:
When a door is opened with the ignition switch
off, the interior lamps up to a luminance of 100
percent. When a door is closed, the interior lamps
dims at a luminance of 65 percent, and goes off
30 seconds later. However if the ignition switch is
turned ON or if a door is locked while the interior
lamps is dimming, the dome lamp will go off at
that point.
When a door is opened with the ignition switch
ON, the interior lamps up at a luminance of 100
percent. When a door is closed, the interior lamps
go off.
When the ignition key is removed with all doors
closed, the interior lamps up at a luminance of
100 percent, and goes off 30 seconds later. How-
ever if the ignition key is inserted again or if a
door is locked while the interior lamps is lighting,
the interior lamps will go off at that point.
To check keyless entry operations more easily,
the interior lamps is flashed once when the doors
are locked. When the doors are unlocked, the
interior lamps at a luminance of 100 percent, and
go off 15 seconds later.
NOTE: The dimmer function can be customised on
vehicles equipped with a multi center display (middle
grade type). Refer to P.54B-486.
NOTE: The dotted lines indicate that lighting mode
when the ignition switch is turned ON, door is locked,
or any door is opened during the timer illumination
time. FUNCTION CONTROL ECU

GENERAL DESCRIPTION
HEATER, AIR CONDITIONING AND VENTILATION55-3
GENERAL DESCRIPTIONM1552000100351
The heater and cooling units are combined in a sin-
gle unit, which, with the mode film damper and flow
rate control valve in the heater unit, reduces ventila-
tion resistance, increases fan power, and decreases
noise.
SAFETY PRECAUTIONS
Wear safety goggles and gloves when servic-
ing the refrigeration system to prevent
severe damage to eyes and hands.
Because R-134a refrigerant is a hydro fluorocarbon
(HFC) which contains hydrogen atoms in place of
chlorine atoms, it will not cause damage to the ozone
layer.
Ozone filters out harmful radiation from the sun. To
assist in protecting the ozone layer, Mitsubishi
Motors Corporation recommends an R-134a refriger-
ant recycling device.
Refrigerant R-134a is transparent and colorless in
both the liquid and vapor state. Since it has a boiling
point of
29.8C (21.64F) at atmospheric pressure,
it will be a vapor at all normal temperatures and pres-
sures. The vapor is heavier than air, non-flammable,
and non-explosive. The following precautions must
be observed when handling R-134a.
Do not heat R-134a above 40C (104.0F) or it
may catch fire and explode.
R-134a evaporates so rapidly at normal atmospheric
pressures and temperatures that it tends to freeze
anything it contacts. For this reason, extreme care
must be taken to prevent any liquid refrigerant from
contacting the skin and especially the eyes. Always
wear safety goggles when servicing the refrigeration
part of the A/C system. Keep a bottle of sterile min-
eral oil handy when working on the refrigeration sys-
tem.1. If any liquid refrigerant gets into your eyes, use a
few drops of mineral oil to wash them out. R-134a
is rapidly absorbed by the oil.
2. Next, splash your eyes with plenty of cold water.
3. Call your doctor immediately even if irritation has
ceased.
Keep R-134a containers upright when charging
the system.
In most instances, moderate heat is required to bring
the pressure of the refrigerant in its container above
the pressure of the system when charging or adding
refrigerant.
A bucket or large pan of hot water not over 40
C
(104.0
F) is all the heat required for this purpose. Do
not heat the refrigerant container with a blow torch or
any other means that would raise temperature and
pressure above this temperature. Do not weld or
steam-clean on or near the system components or
refrigerant lines.
A leak detector for R-134a should be used to
check for refrigerant gas leaks.
Do not allow liquid refrigerant to touch bright
metal or it will be stained.
When metering R-134a into the refrigeration system,
keep the supply tank or cans in an upright position. If
the refrigerant container is on its side or upside
down, liquid refrigerant will enter the system and
damage the compressor.
Refrigerant will tarnish bright metal and chrome sur-
faces, and in combination with moisture can severely
corrode all metal surfaces. ITEM SPECIFICATION

GENERAL DESCRIPTION
HEATER, AIR CONDITIONING AND VENTILATION55-4
OPERATION
.
CONDENSER FAN AND RADIATOR FAN
CONTROL
The ECU judges the required revolution speed of
radiator fan motor and condenser fan motor using
the input signals transmitted from A/C switch, output
shaft speed sensor and engine coolant temperature
sensor. The ECU activates the fan control relays to
drive the radiator fan motor and condenser fan
motor.
.
COMPRESSOR CONTROL
When operating the air conditioning switch
The air thermo sensor, which senses the temper-
ature of the air flowing out of the evaporator,
deactivates the compressor at 3
C (37.4F) or
below.
The dual pressure switch turns OFF when the
refrigerant pressure becomes excessively high or
low, thus protecting the compressor circuit (See
Table below).
When the air thermo sensor is activated, and the
ignition switch, blower switch, and air condition-
ing switch are ON, the A/C compressor clutch
relay is energized.
When operating the mode selection dial
The air conditioning will work when the mode
selection dial is set to the "Defroster" or
"Defroster/foot" position, or the temperature con-
trol dial is set to the "MAX A/C" position. In other
dial positions, when the air conditioning switch is
turned on, the air conditioning will work.

WINDSHIELD WIPER AND WASHER
GENERAL DESCRIPTIONM1511000100558
WINDSHIELD WIPER AND WASHER
OPERATION
.
WINDSHIELD LOW-SPEED (AND
HIGH-SPEED) WIPER OPERATION
If the windshield low-speed wiper switch is turned
to the ON position with the ignition switch at the
"ACC" or "ON" position, the column switch sends
a low-speed wiper ON and high-speed wiper OFF
signals to the front-ECU. This turns the wiper sig-
nal on and the wiper speed control relay off
(low-speed), causing the wipers to operate at
low-speed.
If the windshield high-speed wiper switch is
turned to the ON position, the column switch
sends a low-speed wiper OFF and high-speed
wiper ON signals to the front-ECU. This turns
both the wiper signal and the wiper speed control
relay on (high-speed), causing the wipers to
operate at high-speed.
NOTE: The windshield wiper speed is adjustable
with the built-in wiper speed control relay.
High-speed operations take place when the wiper
speed control relay is set to "ON" and low-speed
operations take place when the wiper speed control
relay is set to "OFF".
.
WINDSHIELD INTERMITTENT WIPER
OPERATION
The ETACS-ECU calculates the wiper operation
interval according to the voltage signal sent from the
column switch. Then the ETACS-ECU sends a signal
to the front-ECU. The front-ECU determines the
wiper operation interval and turns on the wiper relay
signal relay. This causes the wiper auto stop relay to
turn on. Then the wiper auto stop relay will turn off
after the wipers reach the park position. This causes
the wiper signal relay and then the wipers to turn off.
If the wiper signal relay remains off for the wiper
operation interval, the relay turns on again, causing
the wipers to operate in intermittent mode.
.
WINDSHIELD MIST WIPER OPERATION
If the windshield mist wiper switch is turned to the
ON position with the ignition switch at the "ACC"
or "ON" position, the mist wiper high-speed oper-
ation signal is sent to the front-ECU. This signal
turns on the wiper speed control relay, causing
the wipers to work at high-speed while the mist
switch is on.
While the windshield mist wiper switch remains
turned on when the intermittent mode is still work-
ing, the wipers work as the mist wiper. However,
the wipers return to the intermittent mode again
when the switch is changed back to "INT" posi-
tion.
To prevent the windshield mist wiper from operat-
ing when the windshield wiper switch is turned
OFF, the windshield mist wiper does not work for
0.5 second after the windshield intermittent wiper
switch, the windshield low-speed wiper switch
and the windshield high-speed wiper switch are
turned OFF.
.
WINDSHIELD WASHER OPERATION
If the windshield washer switch is turned to the
ON position with the ignition switch at "ACC" or
"ON" position, the windshield washer ON signal is
sent to the front-ECU. After 0.3 second, the wind-
shield wiper signal turns on. After the windshield
washer switch signal turns off, the windshield
wiper signal turns off in three seconds.
If the windshield washer switch is turned on while
the windshield wiper is at intermittent mode, and
the windshield washer switch is turned OFF
within 0.2 second, the wiper works only once to
perform mist operation. When the windshield
washer switch is turned on for more than 0.2 sec-
ond, the wiper performs the same movement as
normal condition from the time when 0.2 second
has elapsed, and then returns to intermittent
operation.
WINDSHIELD WIPER AND WASHER DIAGNOSISM1511000700389
The windshield wiper and washer are controlled by
the Simplified Wiring System (SWS). For trouble-
shooting, refer to GROUP 54B, SWS Diagnosis
P.54B-10.NOTE: Even when the ETACS-ECU has failed, the
windshield wiper can work at low speed as fail-safe
mode. (Normally, the windshield wiper operates
when the ignition switch is at the "ACC" position. But,
if it enters the fail-safe mode, the wiper can operate
only when the ignition switch is at the "ON" position.)

KEYLESS ENTRY SYSTEM
BODY42-68
If none of the doors is opened or the ignition key
is not inserted in the ignition switch within 30 sec-
onds after the doors are unlocked using the
transmitter, the ETACS-ECU will relock the doors
automatically. This is called "Timer lock function."
This timer lock function prevents accidental
unlocking of doors. The adjustment function
allows you to change the timer lock period from 30 seconds (default setting) to 60, 120 or 180
seconds. For further details on using the
multi-center display (middle grade type) to adjust
the timer lock period, refer to GROUP 54B,
On-vehicle Service P.54B-486.
NOTE: The timer lock period begins when the doors
are unlocked, and ends when the doors is relocked
automatically.
KEYLESS ENTRY SYSTEM DIAGNOSISBGBCJGAI

LUBRICATION AND MAINTENANCE
GENERAL00-34
LUBRICATION AND MAINTENANCEM1001001200336
Maintenance and lubrication service recommenda-
tions have been compiled to provide maximum pro-
tection for the vehicle owner's investment against all
reasonable types of driving conditions. Since these
conditions vary with the individual vehicle owner's
driving habits, the area in which the vehicle is oper-
ated and the type of driving to which the vehicle is
subjected, it is necessary to prescribe lubrication and
maintenance service on a time frequency as well as
mileage interval basis.
Oils, lubricants and greases are classified and
graded according to standards recommended by the
Society of Automotive Engineers (SAE) and the Aus-
tralian Petroleum Institute (API).
MAINTENANCE SCHEDULES
For Information on service maintenance refer to the
"Service handbook".
ENGINE OIL
Tests have shown that laboratory animals
develop skin cancer after prolonged contact with
used engine oil. Accordingly, the potential exists
for humans to develop a number of skin disor-
ders, including cancer, from such exposure to
used engine oil. Therefore, when changing
engine oil, be careful not to touch it as much as
possible. Protective clothing and gloves, that
cannot be penetrated by oil, should be worn. The
skin should be thoroughly washed with soap and
water, or use waterless hand cleaner, to remove
any used engine oil. Do not use petrol, thinners,
or solvents.Either of the following engine oils should be used:
1. Engine oil conforming to the ACEA classification:
"For service A1, A2 or A3.
2. Engine oil conforming to the API classification:
"For service SG" or higher.
FUEL USAGE STATEMENT
Using leaded petrol in this car will damage the
catalytic converters and heated oxygen sensors,
and affect the warranty coverage validity.
This vehicle must use unleaded petrol only.
This vehicle has a fuel filler tube which is especially
designed to accept only the smaller-diameter
unleaded petrol dispensing nozzle.
The 3.8L model is designed to operate on unleaded
petrol having an octane rating (DIN 51607) of 90
RON or higher.
.
PETROL CONTAINING ALCOHOL
Some petrol sold at service stations contain alcohol
although they may not be so identified.
Using fuels containing alcohol is not recommended
unless the nature of the blend can be determined as
being satisfactory, as follows.
Gasohol: A mixture of 10% ethanol and 90%
unleaded gasoline may be used in your vehicle. If
driveability problems are experienced as a result of
using gasohol, it is recommended that the vehicle be
operated on petrol.
Methanol: Do not use petrol containing methanol
(wood alcohol). Using this type of alcohol can result
in vehicle performance deterioration and damage
critical parts in the fuel system components. Fuel
system damage and performance problems resulting
from the use of petrol containing methanol may not
be covered by the new vehicle warranty.
MATERIALS ADDED TO FUEL
Indiscriminate use of fuel system cleaning agents
should be avoided. Many materials intended for gum
and varnish removal may contain highly active sol-
vents or similar ingredients that can be harmful to
gasket and diaphragm materials used in fuel system
component parts.
