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

Before removing the 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 installing in the seat. Always handle it with care.
1. Remove the front leg cover and rear leg cover (LH/RH).
2. Slide the seat until the body mounting bolts are visible and a tool can be inserted.
3. Remove mounting bolts from vehicle.
4. Disconnect both battery cables.
5. Disconnect harness connector from under seat cushion.
6. Remove fastening clips under seat cushion, and remove seats
from vehicle.
