Head Restraint Release Solenoid: Service and Repair

Resetting triggered NECK-PRO head restraint
If the NECK-PRO head restraints are triggered in an accident, you must reset the head restraints on the driver's and front-passengers seat. If you do not, the additional protection will not be available in the event of anther rear-end collision. You can recognize when head restraints have been triggered by the fact they have been moved forwards and can no longer be adjusted.
