Active head restraint
In the event of a rear-end collision with a cer‐
tain severity, the active head restraint automat‐
ically reduces the distance from the head.
Reduced protective function
▷ Do not use seat or head restraint
covers.
▷ Do not hang objects, e.g., clothes hangers,
on the head restraints.
▷ Only attach accessories approved by BMW
to the seat or head restraint.
Otherwise, the protective function of the active
head restraint will be impaired and the per‐
sonal safety of the occupants will be endan‐
gered.◀
In the case of strain caused by accidents or
damage:
Have the active headrest checked and if nec‐
essary replaced.
