SRS components are located in this area. Review the
S
RS component locations (see page 24-11) and the
precautions and procedures (see page 24-13) before
doing repairs or service.
 Check the operation of the driver’s seat position sensor after any of these actions (see page 24-29):
– Driver’s seat position sensor replacement
– Cover plate (front side of driver’s seat slide rail) replacement
 Calibrate the ODS unit after any of these actions (see page 24-27):
– Front passenger’s seat replacement (including any seat components)
– Replacement of the front seat weight sensors
– After a vehicle collision
NOTE:  Use the appropriate tool from the KTC trim tool set to avoid damage when removing components.
 Take care not to tear or damage the seat covers.
 On the passenger’s seat, do not touch the OPDS sensor in the seat-back pad, and keep it away from oil.
Oil can corrode the sensor caution it to fail.
 Put on gloves to protect your hands.
1. Remove the front seat (see page 20-118).
2. Remove the head restraint. 3

. From under the seat cushion, detach the side
airbag connector clip (A). On the driver’s seat,
disconnect the seat-back heater connector (B).
4. Release the hooks (C) from the seat cushion frame spring (D). Remove the wire ties (E), and pull the
side airbag harness (F) and the seat-back heater
harness (G) (driver’s seat) out through the slits (H)
in the seat cushion cover (I). Turn over the seat
cushion cover, and release the hooks (J).
