With side airbag: Remove the side airbag (see page 23-169, and release the hooks (A) from the airbag module holder (B). Release the hooks (A) and hook springs (B), then loosen the seat-back cover (C).

Pull out the headrest guides (A) while pinching the end of the guides, and remove them. Pull back the seat-back cover all the way around, then remove it. Install the cover in the reverse order of removal, and note these items: To prevent wrinkles when installing a seat-back cover, make sure the material is stretched evenly over the pad before securing the hooks and hook springs. Make sure the side airbag harness and OPDS harness (passenger's seat) are routed properly. If necessary, reinstall the OPDS control unit (see page 23-39).
