2. PASSENGER’S SEAT
CAUTION:
•If the seat cushion cover is removed or re-
placed, make sure to perform passenger detec-
tion system adjustment after installing the seat
to the vehicle. CALIBRATION (REZEROING), OPERATION,
Subaru Select Monitor.>
Failure to do so may cause improper activation
of passenger’s airbag.
•The passenger detection system (passenger
seat only) control unit, passenger detection
sensor, seat cushion pad and seat cushion
frame are considered as a single seat cushion
pad and frame assembly. Never remove the
passenger detection control unit or the pres-
sure sensor from the seat cushion frame.
•If the seat cushion cover is removed, make
sure to replace the wire on the seat cushion
side with a new wire.
1) Remove the seat from vehicle. PASSENGER’S SEAT, REMOVAL, Front Seat.>
2) Refer to the disassembly procedures for the driv-
er’s seat.
NOTE:
The back side of the seat cushion is affixed by a
hook (A) and hog ring (B).
D: ASSEMBLY
CAUTION:
When the backrest cover is not installed se-
curely, the side airbag module may not be de-
ployed properly, therefore keep strictly to the
following procedure.
•Be careful not to stain or damage the back-
rest cover during assembly.
•The back rest cover of the side airbag module
are to be tightened and fixed together with the
attachment nuts for the side airbag module as-
sembly.
•Always use new hog rings.
•Secure the hog ring using hog ring pliers.
•Install the hog rings to the specified points
securely and make sure that no wrinkle or twist-
ing on backrest cover.

2. PASSENGER’S SEAT
CAUTION:
Make sure to adhere to the following rules when
assembling the passenger seat. Improper work
procedures can cause the passenger detection
system to not operate properly.
•If the seat cushion cover is removed or re-
placed, make sure to perform passenger detec-
tion system adjustment after installing the seat
to the vehicle. CALIBRATION (REZEROING), OPERATION,
Subaru Select Monitor.>
Failure to do so may cause improper activation
of passenger’s airbag.
•The passenger detection system (passenger
seat only) control unit, passenger detection
sensor, seat cushion pad and seat cushion
frame are considered as a single seat cushion
pad and frame assembly. Never remove the
passenger detection control unit or the pres-
sure sensor from the seat cushion frame.
•If the seat cushion cover is removed, make
sure to replace the wire on the seat cushion
side with a new wire.
•Make sure to install the hog rings/clips to the
specified locations. Do not reuse hog rings.
Assemble in the reverse order of disassembly.
1) Assemble the seat cushion in the reverse order
of disassembly.
2) Assemble the backrest in the reverse order of
disassembly.
3) When assembling the backrest assembly to the
seat cushion assembly, fill up the gap in the front
side of slide rail LH and in the rear side of slide rail
RH using cloth etc.
4) Temporarily tighten the reclining hinge bolts in
the order of (1) through (4), to an extent that the
seat back assembly is not locked.
5) Hold the seat cushion assembly securely, and
tighten the reclining hinge bolts in the order de-
scribed above until they reach the specified torque.
CAUTION:
Do not touch the backrest assembly when tight-
ening the reclining hinge bolts.
6) Assemble each harness, inner belt assembly
and each cover in the reverse order of removal.
Tightening torque:
Refer to “COMPONENT” of “General Descrip-
tion”. Description.>
E: INSPECTION
Check that no tear or fray on the backrest cover
and seat cushion cover.
CAUTION:
If there are tears or looseness in the back rest
cover or seat cushion covers, do not attempt to
repair. Replace with a new cover. Repairing the
cover may cause improper operation of the side
airbag or the passenger detection system.

the Subaru Select Monitor.
NOTE:
•Set the sensor so as not to let the alarm on nor-
mal vibration (reclining to the door, hit the ball and
etc.).
•Set the sensor to operate the alarm with hitting
the door or window glass, etc. continuously like a
mayhem by robbery.
•Ask the customer about parking situation for set-
