Head Restraint System: Service and Repair

Resetting activated head restraints

If the activated head restraints have been triggered in an accident, reset the activated 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. Head restraints that have been triggered are moved forwards and can no longer be adjusted.

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

WARNING
When pushing back the 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.
