B: CAUTION
•When servicing a vehicle, be sure to turn the ig-
nition switch to OFF, disconnect the ground cable
from battery, and wait for more than 20 seconds
before starting work.
•The airbag system is fitted with a backup power
source. After disconnecting the battery ground ca-
ble, the airbag may deploy if you do not wait for
more than 20 seconds before starting the service of
airbag system.
•If the airbag warning light illuminates, repair the
vehicle immediately. Otherwise, the airbag or pre-
tensioner may inflate incorrectly, or not inflate in
collision.
•If sensors, airbag module, airbag control module,
pretensioner or harness is deformed or damaged,
replace with new part.
•When checking the airbag system, be sure to
use a digital circuit tester. Use of an analog circuit
tester may cause the airbag to activate erroneously
due to a minimal current inside tester.

General Description
AIRBAG SYSTEM
•When checking, use a test harness (1). Damage
to connector terminal cause malfunction. Do not di-
rectly apply the tester probe to connector terminal
of airbag.
•Do not allow water or oil to come in contact with
the connector terminals. Also do not touch the con-
nector terminals.
•Do not check continuity of the airbag modules for
driver’s side, passenger’s side and curtain, or the
pretensioner.
•If damage, open circuit or rust is found on airbag
system wire harness, do not use a soldering equip-
ment to repair. Replace the faulty harness with a
new genuine part.
•Install the wire harness securely with the speci-
fied clips to avoid interference or tangled with other
parts.
•When painting or performing sheet metal work
on the front part of the vehicle, including the front
wheel apron, front fender and front side frame, re-
move the front sub sensors and wire harness of air-
bag system.
•When painting or performing sheet metal work
on the side of the vehicle, including the side sill,
center pillar and front and rear doors, remove the
side airbag sensors and wire harness of the airbag
system.
•Do not use the airbag or pretensioner parts from
other vehicles. Always replace the defective parts
with new parts.
•Never reuse a deployed airbag module and pre-
tensioner.

General Description
AIRBAG SYSTEM
•Do not discard the uninflated airbag or preten-
sioner.
•When airbag control module, front sub sensor,
side airbag sensor and curtain airbag sensor are
removed, do not reuse the bolts and nuts of them.
Always use new bolts and nuts for them.
•Do not drop each airbag module, airbag control
module and each sensor, or store these parts un-
der high temperature over 93°C (199°F), or let wa-
ter, oil or grease get on them; the internal parts may
be damaged or the reliability may be greatly low-
ered.
•After removal of each parts for airbag system,
keep them with the pad facing upward on a dry,
clean and flat surface without heat, light sources,
moisture and dust.
•The airbag modules for driver’s, passenger’s,
side or curtain, or the pretensioner must not be dis-
assembled.
•When performing attachment of the steering
wheel and steering roll connector, make sure to
perform adjustment of the steering roll connector.
•The removed front seat with airbag module must
be kept at least 200 mm (8 in) away from walls and
other objects.

Collision
A: REPLACEMENT
Replace the following parts when the airbag is de-
ployed.
1. FRONT COLLISION
1) Driver’s airbag module
2) Passenger’s airbag module
3) Driver’s seat belt (Pretensioner)
4) Passenger’s seat belt (Pretensioner)
5) Airbag control module
6) Front sub sensor (L/R)
7) Roll connector
8) Instrument panel (for integrating with passen-
ger’s airbag module)
9) Passenger side seat cushion pad and frame as-
sembly
2. SIDE COLLISION
1) Airbag control module
2) Side airbag module (operating side seat back-
rest)
3) Side airbag sensor (operating side)
4) Curtain airbag module (operating side)
5) Curtain airbag sensor (operating side)
3. INSPECTION OF OTHER PARTS
Check for the following parts, and replace the dam-
aged parts with new parts.
1) Steering wheel and steering shaft
Check the steering shaft for mounting conditions
and deflection of front and rear, upward and down-
ward directions, and deflection of front and rear di-
rection with tilt lever released. (After a collision,
there is a good chance that the shock absorbing
part of steering shaft may have operated.)
2) Check the connectors of airbag module, preten-
sioner, etc. for damage, and also check each har-
ness for pinch and connector damage. Replace the
harness as a unit if damage is found.
3) Check the seat cushion frame, backrest, seat rail
and headrest for deformation, distortion, crack, and
installing condition and play.
4) For passengers seat, replace the seat cushion
frame assembly with new one if the seat cushion
frame is deformed or cracked.
5) If there are tears or loosening in the passenger
side seat cushion cover, it may interfere with the
proper operation of the passenger detection sys-
tem. Replace with a new cushion cover.
6) Be sure to perform the system calibration for the
occupant detection system after removing or re-
placing the passenger seat cushion cover. Failure
to do so may cause improper operation of the pas-
senger detection system. SYSTEM CALIBRATION (REZEROING), OPERA-
TION, Subaru Select Monitor.>
7) Use the Subaru Select Monitor to check whether
the drivers seat position sensor and the drivers and
the front left/right seat belt buckle switches are op-
erating normally.
