SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
(1)A Supplemental Restraint System (SRS), which uses a driver-side air bag, has been installed in the 3000GT.(2)The SRS includes the following components: impact sensors, SRS diagnosis unit: SRS warning light, air bagmodule, clock spring, interconnecting wiring. Other SRS-related components (that may have to be
removed/installed in connection with SRS service or maintenance) are indicated in the table of contents byan asterisk (*).
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 (from
rendering 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
-Supplemental Restraint System (SRS), before beginning any service or maintenance of any component of theSRS or any SRS-related component.

SERVICE POINTS OF REMOVALM37GBAV1. REMOVAL OF AIR BAG MODULE
(1) Remove the air bag module mounting nut using a
socket wrench from the back side.
(2) To remove the clock spring connector (squib connector)
from the air bag module, force the lock outward and pry
it with a standard screwdriver, as shown in the
illustration at the left, to make sure that no undue force
is exerted to the connector when it is removed.
CautionWait at least 30 seconds after disconnecting the
battery cable before doing any further work. The
SRS system is designed to retain enough voltage todeploy the air bag for a short time even after the
battery has been disconnected, so serious injury
may result from unintended air bag deployment if
work is done on the SRS system immediately afterthe battery cable is disconnected.
(3) The removed air bag module should be stored in a
clean, dry place with the pad cover face up.
2. REMOVAL OF STEERING WHEEL
Remove the steering wheel by using a steering wheel
puller.
CautionDo not hammer on the steering wheel to remove it;
doing so may damage the collapsible mechanism.
SERVICE POINT OF INSTALLATIONM37GDAR2. INSTALLATION OF STEERING WHEEL
Line up the “NEUTRAL” mark of the clock spring with the
mating mark before installing the steering wheel.
CautionIf the clock spring’s mating mark is not properly
aligned, the steering wheel may not be completely
rotational during a turn, or the flat cable within the
clock spring may be severed, obstructing normal
operation of the SRS and possibly leading to serious
injury to the vehicle’s driver.1
