Resetting activated head restraints
̄ 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.
