restraint if no one will be sitting on the seat in
question. Reinstall the head restraint before
transporting anyone on that seat. Otherwise,
the passenger will be without protection from
the head restraint.<
Height
Adjust the head restraint so that its center is
approximately at ear level.
Distance
Adjust the distance so that the head restraint is
as close as possible to the back of the head.
Front active head restraints
In a rear collision of a sufficient strength, the
active head restraint reduces the distance to
the head.
Do not use seat or head restraint covers
that could impair the function of the active
head restraint. Otherwise, the protective func-
tion of the active head restraint will not be
ensured and its full potential in reducing the risk
of injury in the event of a rear collision may not
be realized.
In the event of malfunctions, deactivation or
triggering of the active head restraints, have the
testing, repair and removal executed only by a
BMW center or a workshop that works accord-
ing to repair procedures of BMW with corre-
spondingly trained personnel and that has the
required explosives licenses. Unprofessional
attempts to work on the system could lead to
failure in an emergency or to undesired airbag
activation, either of which could result in per-
sonal injury.<
For technical reasons, the head restraint
cannot be removed.<
