head restraints
For information on head restraint adjust-
ment, see “Seats” (

factory-set position range and the
system recognizes the current seat
position to be rearward enough for
easy entry and exit, the driver’s seat
will not move to the rear when the
easy-entry/exit feature is activated.
iFor safety reasons, the driver’s seat will
not return to its last set position with
the easy-entry/exit feature activated if
the system recognizes the last set posi-
tion as an extreme forward position.
Instead, the driver’s seat will remain at
or move to a factory-set maximum
forward position. To again fully return
the driver’s seat to your last set posi-
tion or to memory position, adjust the
seat to the desired position or press
and hold the respective memory
position switch (
page 120).
iAdjust the head restraint in such a way
that it is as close to the head as
possible.Warning!
G
For your protection, drive only with properly
positioned head restraints.
Adjust head restraint so that the center of
the head restraint supports the back of the
head at eye level. This will reduce the poten-
tial for injury to the head and neck in the
event of an accident or similar situation.
Do not drive the vehicle without the seat
head restraints. Head restraints are intend-
ed to help reduce injuries during an
accident.
