Honda Odyssey Service Manual: Headrests

Front Seat Active Head Restraint Inspection

NOTE: If the vehicle has been in a collision, always inspect the active head restraint, even if they appear reusable, by doing the following procedure.

1. Move the seat-back to the fully upright position. Raise the head restraint to the highest position.

2. Apply the masking tape (A) on the top of the head restraint (B).

3. Make the mark (C) at the center point of the head restraint. Use the mark for the measurements in step 4.

4. Push the head restraint (A) forward, and measure the horizontal head restraint movement. The head restraint should move more than 50 mm (1.96 in) without resistance. If it is less than 50 mm (1.96 in), or the head restraint does not move smoothly, replace the seat frame.
