FRONT SEAT
Revision: 2005 July 2005 FX
REMOVAL
When removing or installing the seat trim, carefully handle it to keep dirt out and avoid damage.
CAUTION:

Before removing the front seat, turn ignition switch OFF, disconnect both battery cables and wait
at least 3 minutes.

When checking the power seat circuit for continuity using a circuit tester, do not confuse its con-
nector with the side air bag module connector. Such an error may cause the air bag to deploy.

Do not drop, tilt, or bump the side air bag module installing in the seat. Always handle it with care.
1. Remove the seat cushion outer finisher cover.
2. Remove the front seat belt anchor bolt. Refer to SB-3, "
Removal
and Installation of Front Seat Belt" .
CAUTION:
Set the front and rear cushion lifter to the down position.
3. Remove the screw.
4. Remove the seat cushion forward finisher lid.
5. Remove the seat cushion forward finisher.
6. Remove the seat cushion outer finisher.
7. Remove the power seat memory switch assembly.
