CAUTIONS & WARNINGS
SUPPLEMENTAL RESTRAINT SYSTEM (AIR BAG)
NOTE: See the AIR BAG RESTRAINT SYSTEM article in the
ACCESSORIES/SAFETY EQUIPMENT Section.
Modifications or improper maintenance, including incorrect
removal and installation of the Supplemental Restraint System (SRS),
can adversely affect system performance. DO NOT cover, obstruct or
change the steering wheel horn pad in any way, as such action could
cause improper function of the system. Use only plain water when
cleaning the horn pad. Solvents or cleaners could adversely affect the
air bag cover and cause improper deployment of the system.
WARNING: To avoid injury from accidental air bag deployment, read and
carefully follow all warnings and service precautions. See
appropriate AIR BAG RESTRAINT SYSTEM article in the
ACCESSORIES/SAFETY EQUIPMENT section.
CAUTION: Disconnect negative battery cable before servicing any air
bag system, steering column or passenger side dash
component. After any repair, turn ignition key to the ON
position from passenger's side of vehicle in case of
accidental air bag inflation
AIR CONDITIONING SERVICING
WARNING: R-134a service equipment or vehicle A/C systems SHOULD NOT
be pressure tested or leak tested with compressed air. Some
mixtures of air/R134a have shown to be combustible at
elevated pressures. These mixtures are dangerous and may
cause fire and/or explosions. See the appropriate
A/C SYSTEM GENERAL SERVICING article in the AIR CONDITIONING
& HEAT section.

Remove horn pad and steering wheel. See Figs. 1-6. See
STEERING COLUMN TESTING/REMOVAL & INSTALLATION table for figure
directory on specific model. Remove knee protector and upper and lower
column covers (if necessary). On Eclipse, remove hood lock release
handle and air ducts. On all models, remove any necessary cable bands,
and remove steering column switch. To install, reverse removal
procedure.
Removal (Stealth & 3000GT)
1) Disconnect negative battery cable. Wait 30 seconds, and
then remove air bag module mounting nut from back side of module. To
remove clockspring connector from air bag module, force lock outward
and pry it using a flat screwdriver. Ensure no undue force is exerted
on connector when it is removed. Remove air bag module, and store it
face up. See Fig. 7.
CAUTION: Wait at least 30 seconds after disconnecting battery cable
before continuing servicing.
2) Remove steering wheel and knee protector. Remove upper and
lower column covers. Remove air ducts. Remove right and left steering
column switches.
WARNING: DO NOT hammer on steering wheel. Collapsible steering column
mechanism may be damaged.
Installation
1) To install, reverse removal procedure. Before installing
steering wheel, center clockspring by lining up NEUTRAL mark of
clockspring with mark on steering column. To complete installation,
reverse removal procedure. DO NOT reconnect negative battery cable
until air bag module is installed.
2) After installation is complete, turn ignition on from
passenger side of vehicle. Supplemental Restraint System (SRS) light
on dash should come on for approximately 7 seconds. If SRS light does
not come on, stays on or flashes, repair air bag system.
