In the event of a rearend collision, the NECK-PRO active front head restraints on the front seats are designed to move forward in the direction of travel. They thus provide the head with increased support earlier on in the collision sequence. The NECK-PRO active front head restraints will move forward whether the seats are occupied or not.

G Warning! Do not attach any objects (e.g. hangers) to the head restraint posts.

G Warning! Only use seat or head restraint covers which have been tested and approved by MercedesBenz for your vehicle model. Using other seat or head restraint covers may interfere with or prevent the activation of the NECK-PRO active front head restraints and/ or the deployment of the front side impact air bags.

When the NECK-PRO active front head restraints have been triggered in an accident, the NECK-PRO active front head restraints must be reset.

All of the PRE-SAFE® system settings can be readjusted following the critical driving event. If the seat belts do not release: X Adjust the seat backrest or seat slightly to the rear until the seat belt tension is reduced. The locking mechanism releases. !
