OPERATION
L
lBattery positive voltage is continuously applied to the key-reminder switch.l
If the driver’s door is opened (door switch ON) with the key inserted in the ignition switch (key-reminderswitch ON), the buzzer sounds to warn that the key has been left in the switch.
&eat belt warning>
lWhen the ignition switch is turned on, the timer circuit and pulse circuit will flicker the seat belt warning
light for approx. 6 seconds with the buzzer intermittently sounding.
lIf the seat belt is fastened for the while, the seat belt switch will be turned off and the buzzer will
stop.

OPERATION
L
0For models equipped with the M/T, the clutch
pedal position switch contact is switched OFF
when the clutch pedal is depressed; when the
ignition switch is then switched to the “ST’ posi-tion, electricity flows to the starter relay and
the starter motor, the contact (magnetic switch)of the starter is switched ON and the starter
motor is activated.
NOTEIf the ignition switch is switched to the “ST
position without the clutch pedal being de-
pressed, electricity flows to the starter relay
(coil), the clutch pedal position switch (contacts)
and to ground, with the result that the contacts
of the starter relay are switched OFF, and, be-
cause the power to the starter motor is thereby
interrupted, the starter motor is not activated.lFor models equipped with the
AIT, when the
ignition switch is switched to the “ST’ position
while the selector lever is at the “P” or “N” posi-
tion, the contact (magnetic switch) of the starter
is switched ON and the starter motor is activated.
TROUBLESHOOTING HINTSThe starter motor does not operate at all.
l Check the starter (coil).
lCheck for poor contact at the battery terminals
and starter.l Check Park/Neutral position switch.
l Check clutch pedal position switch.
l Check starter relay.
l Check theft-alarm starter relay.
l Check key reminder switch.

WARNINGS REGARDING SERVICING OF SUPPLEMENTAL RESTRAINT SYSTEM (SRS) EQUIPPED VEHICLES
WARNING!
(1) Improper service or maintenance of any component of the
SRS, or any SRS-related component, can lead to personal
injury or death to service personnel (from inadvertent firing of the air bag) or to the driver and passenger (from render-
ing the SRS inoperative).
(2) Service or maintenance of any SRS component or
SRS-related component must be performed only at an authorized
MITSUBISHI dealer.
(3)MITSUBISHI dealer personnel must thoroughly review this manual, and especially its GROUP 52B
TSupplemental Re-
straint System (SRS) and GROUP 00 -Maintenance Service before beginning any service or maintenance of any com-
ponent of the SRS or any
SRS-related component.
NOTE
The SRS includes the following components: impact sensors, SRS diagnosis unit, SRS warning light, air bag module, clock spring
and interconnecting wiring. Other SRS-related components (that may
h,a”” to be removed/installed in connection with SRS serviceor maintenance) are indicated in the table of contents by an asterisk ( ).

OPERATION
l
When the ignition key is at the “ON” position,the fuel gauge is activated.
l
When there is much fuel, the unit’s resistanceis small and the current flowing in the circuit
is great, so the gauge’s indicator indicates inthe “F” area.
l When there is little fuel, the unit’s resistance
is high and the current flowing in the circuit
is small, so the gauge’s indicator indicates inthe
“E” area.

lWhen the ignition key is at the “ON” position,
the engine coolant temperature gauge is acti-
vated.l
When the engine coolant temperature is high,
the unit’s resistance is low and there is a greatflow of current in the circuit, so the gauge’s
indicator indicates in the “H” area.
l
When the engine coolant temperature is low,
the unit’s resistance is high and there is a smallflow of current in the circuit, so the gauge’s
indicator indicates in the “C” area.
/Speed sensor (electrical speedometer type)>l Pulses are produced in accordance with the
vehicle speed, and vehicle-speed signals areinput to systems (the MFI system, etc.) that
regulate according to the vehicle speed.
TROUBLESHOOTING HINTS
1.The fuel gauge doesn’t function, or shows the
incorrect indication.
(1) Disconnect the connector of the fuel pumpand gauge unit assembly; the ‘F” side is
indicated when terminal (5) is then
grounded.l Check the fuel gauge.
2.The engine coolant temperature gauge doesn’t
function, or shows the incorrect indication.
(1)The “l-l” side is indicated when the connector
of the engine coolant temperature gauge
unit is disconnected and then grounded.l
Check the engine coolant temperature
gauge unit.
3. Systems dependent upon control according to
the vehicle speed do not function correctly.l Check the reed switch (mechanical
speedometer type)l Check the speed sensor (electrical
speedometer type)
coil pressure gauge>l
When the ignition key is at the “ON” position,
the oil pressure gauge is activated.
lWhen oil pressure is high, the internal contacts
of the gauge unit are kept closed for a longerperiod of time. This causes more current to
flow in the circuit, and the gauge pointer swings
to the high pressure side.
lWhen oil pressure is low, the internal contactsof the gauge unit open in a shorter period of
time. Therefore, there is less current flowing
in the circuit and the gauge pointer swings to
the low pressure side.

lWhen the ignition key is set to the “ON” position,the gauge indicator will be at
“0”.l
When the engine is started, the indicator will
move from
“0” to the minus (-) side, and then,as the boost level increases, it will move to
the plus
(+) side.
l When the ignition key is placed in the “ON”
position, the voltage gauge operates and indi-
cates a battery voltage of approximately 12 V.l
When the engine is started, the voltage gauge
indicates a battery voltage of 12 to 16 V, indicat-ing that the battery is on charge.
4. The oil pressure gauge doesn’t function, or
shows the incorrect indication.
(1)The “H” side is indicated when the connectorof the oil pressure gauge unit is discon-
nected and then grounded.l Check the oil pressure gauge unit.
5.The meter illumination light does not illuminate.
(1) The tail lights illuminate.l Check the rheostat.
6. The voltage gauge doesn’t function, or shows
the incorrect indication.l Check the voltage gauge.

OPERATION light>l
Battery voltage is always applied to the dome light. When the dome light switch is turned to “ON”,
the dome light will remain lit. After either door is opened if the dome light switch is at “DOOR” position,the dome light will come on.
lWith the dome light turned on (with the ignition switch in the OFF position and with the dome light
switch in the DOOR position), close all doors, and the timer circuit in the ETACS unit will be activatedto gradually vary the voltage for approx. 6 seconds owing to the duty control, and the voltage will
be output to transistor Tr. Since the voltage applied to the dome light gradually decreases, the dome
light will be dimmed.lIf the ignition switch is turned to “ON” while the dome light is lit (while the timer is activated), the
timer circuit will be opened to turn “OFF” transistor Tr. This will immediately turn off the dome light
without dimming. light>-lBattery voltage is always applied to the foot lights and ignition key illumination light.
With the ignition switch in the OFF position, open any door, and all lights will come on.
l
With all lights turned on (with the ignition switch in the OFF position), close all doors, and the timercircuit inside the ETACS unit will operate in the same manner as the dome light to dim all lights.
When the ignition switch is placed in the ON position with all lights turned on (with the timer in operation),the same operation as the dome light will take place.
