Head Restraint System: Service and Repair

Resetting triggered NECK-PRO head restraints

If the NECK-PRO active head restraints have been triggered in an accident, reset the NECK-PRO active head restraints on the driver's and front-passenger seats. Otherwise, the additional protection will not be available in the event of another rear-end collision. NECK-PRO active head restraints that have been triggered are moved forwards and can no longer be adjusted.

WARNING
For reasons of safety, have the NECK-PRO active head restraints checked at an authorized Mercedes-Benz Center after a rear-end collision.

WARNING
When pushing back the NECK-PRO head restraint cushion, make sure your fingers do not become caught between the head restraint cushion and the cover. Failure to observe this could result in injuries.

Resetting the NECK-PRO head restraints requires a lot of strength. If you have difficulty resetting the NECK-PRO head restraints, have this work carried out at a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center.
