1Release lever
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.
iIn addition to the front seat backrests, 
the front seat cushions can also be 
shifted forward to permit easy access 
to the rear whenever the seat is located 
in the rear half of its adjustment range. 
Swivel backrest forward by pulling the 
release lever until the seat moves in a 
combined forward and upward 
movement.

Open the trunk and release the rear 
seat backrest (
page 268).
Fold rear seat backrest slightly for-
ward.
Guide top tether strap between head 
restraint and top of seat back.

2Hook
Fold up anchorage ring1.
Securely fasten hook2, which is part 
of the tether strap, to anchorage 
ring1.
Warning!
G
If the 56 indicator lamp should not 
illuminate, the system is not functioning. 
You must see an authorized Mercedes-Benz 
Center before seating any child on the front 
passenger seat.Warning!
G
Never place anything between seat cushion 
and child seat (e.g. pillow), since it reduces 
the effectiveness of the Occupant Classifi-
cation System. The bottom of the child seat 
must make full contact with the passenger 
seat cushion. An incorrectly mounted child 
seat could cause injuries to the child in case 
of an accident, instead of increasing protec-
tion for the child.
Follow the manufacturer’s instructions for 
installation of child seats.

attached, the child restraint itself can be 
secured. Tighten the top tether strap ac-
cording to the child restraint manufactur-
er’s instructions. Child seat anchors – LATCH type
This vehicle is equipped with two LATCH 
(L
ower A
nchors and T
ethers for CH
ildren) 
type anchors (at each of the rear seats) for 
the installation of a LATCH child seat with 
matching mounting fittings.
If child seats are not installed, the LATCH 
anchors can be folded back between the 
seat cushion and the seat backrest.
iFor safety, make sure the hook2 has 
attached to the anchorage ring1 be-
yond the safety catch, as illustrated.
Warning!
G
Always lock backrest in its upright position 
when rear seat bench is occupied by pas-
sengers, or the extended cargo area is not in 
use. Check for secure locking by pushing 
and pulling on the backrest.
