INSTALL WEBBING (w/ Airbag)

(a) Pass the webbing through the pad hole, and then stretch the webbing so there are no wrinkles.

If there are wrinkles in the webbing, wrinkles will appear on the surface of the cover.

CHECK COVER POSITION

INSTALL COVER

(a) Align the cover of the seatback with the center of the seatback pad and the cover of the seat cushion with the center of the seat cushion pad. Afterward, install the covers starting from the vehicle exterior and working toward the vehicle interior.

(b) While removing wrinkles by hand as shown in the illustration, install the seatback cover by starting from the bottom and working toward the shoulders, and then install the seat cushion cover by starting from the front and working toward the rear.

HINT:

• For Seatback Side:

  When installing the cover to the outer side, install the cover up until the installation area of the outer side headrest support.

• Do not apply an excessive amount of force when covering the corners, as doing so may cause the cover to tear or fray.

If there are wrinkles in the webbing, wrinkles will appear on the surface of the cover.

CHECKS TO PERFORM AFTER WORK IS FINISHED

(a) Smooth the cover as shown in the illustration and make sure that there are no wrinkles.

HINT:

• If wrinkles remain, it is very likely that the covering was not properly performed.

• If waves form in the seam line, it is very likely that the seam allowance is not in the groove or the position of the felt is incorrect.
