REMOVAL
NOTE:
When removing or installing the seat trim, handle it carefully to keep dirt out and avoid damage.
CAUTION:

Before removing the front seat, turn the 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 while installing the seat. Always handle it with
care.

After front side air bag module inflates, front seatback assembly must be replaced.

Front passenger seat is equipped with an Occupant Classification System sensor and control
module. Do not disassemble front passenger seat cushion assembly or remove the trim as this
will affect the Occupant Classification System calibration.

Always replace passenger seat cushion as an assembly.
