Resetting Activated Head Restraints; Vehicles Without Rear Seat Entertainment System - Mercedes-Benz 2008 M-Class Operator's Manual

Practical hints

Resetting activated head restraints

If the active head restraints have been trig-
gered in a rear-end collision, the active
head restraints must be reset. Otherwise,
the active head restraints cannot offer any
additional protection in the event of anoth-
er rear-end collision.
You can tell that the head restraints have
been activated when they have been
moved forward and cannot be adjusted.
Warning!
For safety reasons, have the active head re-
straints checked by an authorized
Mercedes-Benz Light Truck Center after a
rear-end collision.
