Resetting activated head restraints
If the active head restraints have been
triggered 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 active head restraints
have been activated when they have been
moved forward and cannot be adjusted.
1Reset tool
2Active head restraint
Take the reset tool1 out of the
Mercedes-Benz vehicle literature
pouch.
Guide reset tool1 into the rect-
angular opening of active head
restraint2.
Press reset tool1 downward in
direction of arrow until you hear the
head restraint release mechanism
audibly disengage.
Pull out reset tool1.
Firmly press the active head restraint
cushion backward towards the head re-
straint cover in direction of arrow until
it engages.
Repeat this procedure on the active
head restraint for the second front
seat.
After resetting the active head
restraints store reset tool1 in the
Mercedes-Benz vehicle literature
pouch.
For information on active head restraints,
see “Active head restraints” (
page 83).
For information on head restraint adjust-
ment, see “Seats” (
page 43).
iFor your convenience, we recommend that
you have this work carried out by an authorized
Mercedes-Benz Light Truck Center.
You will find the reset tool for manually operating
the active head restraints in the Mercedes-Benz
vehicle literature pouch.
Warning!G
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.
Warning!G
For safety reasons, have the active head
restraints checked by an authorized
Mercedes-Benz Light Truck Center after a
rear-end collision.
!Be careful not to damage upholstery.
