Practical hints Resetting activated head restraints Resetting activated head restraints If the active head restraints (front seats) have been triggered in an accident, the active head restraints must be reset. Otherwise, the active head restraints cannot offer any additional protection in the event of another rear-end collision. You can tell that the head restraints have been triggered when they have been moved forward and cannot be adjusted. Warning! G ! Be careful not to damage upholstery. Press reset tool 1 forward in direction of arrow. Press reset tool downward until you hear the head restraint release mechanism audibly engage. Pull out reset tool 1. Firmly press head restraint cushion backward towards the rear of the vehicle until it engages. Repeat this procedure on the active head restraints for second head restraint. For information on active head restraints, see "Active head restraints" ( page 55). When pushing back the head restraint cushion, take care that your fingers do not become caught between the head restraint cushion and the cover. Failing to do so may lead to injury. i For your convenience, we recommend that you have this work carried out by an authorized Mercedes-Benz Center. You will find the reset tool for manually operating the head restraints in the Mercedes-Benz vehicle literature pouch. Warning! G Take reset tool 1 out of the Mercedes-Benz vehicle literature pouch. Guide reset tool 1 into center of head restraint between head restraint cushion and rear head restraint cover. For safety reasons, have the active head restraints checked by an authorized Mercedes-Benz Center after a rear-end collision. For information on head restraint adjustment, see "Head restraints" ( page 353). 675
