Front Seat Active Head Restraint Inspection

WARNING: This page is about a different car, the 2011 Honda Insight and 2010 Honda Insight. However, it is still accessible from the selected car via links, so may be relevant.

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.

Fold the seat-back forward, then recline the seat-back to the first lock position, and adjust the head restraint to the highest position.
Apply masking tape on the top of the head restraint.
Make marks (A) on both sides at 255 mm (10.0 in) upward from the roots of the head restraint frame (B) along the back of the head restraint (C) surface. Mark a center of these points as a datum point (D).

Push the head restraint (A) forward, and check:
With a scale, measure the level amount of the head restraint movement. The head restraint should move more than 55 mm (2.2 in) without resistance. If it is less than 55mm (2.2 in), or the head restraint doesn't move smoothly, replace the seat-back frame:
- Driver's seat (see DRIVER'S SEAT ).
- Passenger's seat (see PASSENGER'S SEAT ).
