After installing top tether straps, make sure
that the seat backrests are in an upright po-
sition and are properly locked. Check for
secure locking by pushing and pulling on the
seat backrests. If a seat backrest is not
properly locked, the seat backrest could
fold. The child seat would no longer be prop-
erly supported or positioned to provide its
intended benefit.

Activate the override switch when children
are riding in the back seats of the vehicle.
The children could otherwise injure them-
selves, e.g. by becoming trapped in the win-
dow opening.
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Unsupervised use of vehi-

Rear seat head restraints
Warning!
G
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint so that it is close
to the head as possible and the center of the
head restraint supports the back of the head
at eye level. This will reduce the potential for
injury to the head and neck in the event of
an accident or similar situation.
Warning!
G
Do not drive the vehicle without the seat
head restraints installed when the rear seats
are occupied. Head restraints are intended
to help reduce injuries during an accident.
With a rear seat occupied, make sure to
move the respective head restraint up from
the lowest non-use position and have the oc-
cupant adjust the head restraint properly.
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint in such a way that
it is as close to the head as possible and the
center of the head restraint supports the
back of the head at eye level. This will re-
duce the potential for injury to the head and
neck in the event of an accident or similar
situation.
