Self-test Occupant Classification
System
After turning the SmartKey in the starter
switch to position
1 or 2, the
56 indicator lamp 1 located in
the center console illuminates. If an adult
occupant is properly sitting on the front
passenger seat and the system senses the
occupant as being an adult, the
56 indicator lamp will illuminate
and go out after approximately six sec-
onds.
If the seat is not occupied and the system
senses the front passenger seat as being
empty, the 56indicator lamp will
illuminate and not go out. For more information, see “Lamp in center
console” (
page 345).Installation of infant and child restraint
systems
This vehicle is equipped with tether an-
chorages for a top tether strap at each of
the rear seating positions.
1 Anchorage rings
Release rear seat backrest
(page 251).
Fold rear seat backrest slightly for-
ward.
Guide tether strap between head
restraint and top of the seat back.
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.
78 Safety and SecurityOccupant safety
Head restraint must be positioned such
that the top tether strap can pass freely
between the head restraint and the top
of the seat back.
Make sure the tether strap is not twist-
ed.
2 Hook
3 Anchorage ring
Securely fasten the hook 2 to the
anchorage ring 3.
Swing rear seat backrest to the rear
until it engages.
Check the rear seat backrest to be
locked in its upright position
(page 251).
Once the top tether anchorage hook is
attached, the child restraint itself can be
secured. Tighten the top tether strap
according to the child restraint manufac-
turer's instructions. Child seat anchors - LATCH type
To fold anchors out
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 the matching mounting fittings.
The foldable LATCH type anchors are
located between the seat cushion and the
backrest.

Always lock backrest in nearly upright posi-
tion when rear seat bench is occupied by
passengers, or the extended cargo area is
not in use. Check for secure locking by
pushing and pulling on the backrest.

vehicle’s seat belt system. Install child
seat according to the manufacturer’s
instructions.Warning!
G
Children too big for a toddler restraint must
ride in seats using regular seat belts. Posi-
tion shoulder belt across chest and shoul-
der, not face or neck. A booster seat may be
necessary to achieve proper belt positioning
for children from 41 lbs until they reach a
height where a lap/shoulder belt fits proper-
ly without a booster.
Before installing the child seat, make sure
anchors
1
are folded out and locked in
place.
Install child seat according to manufactur-
er’s instructions.

Controls in detail
Memory function*
Memory function*
You can store up to three different settings
per SmartKey.
The following settings are saved for each
stored position:
Driver’s seat, backrest and head
restraint position
Steering wheel position
Exterior rear view mirror positions
These key-dependent memory settings
can be deactivated if desired. For informa-
tion on key-dependent memory settings,
see “Setting key-dependency”
(
page 149). The following settings are not
key-dependent. They are stored when
using the buttons on the passenger door:
Front passenger seat, backrest and
head restraint position.
!Prior to operating the vehicle, the driv-
er should check and adjust the seat
height, seat position fore and aft, and
seat backrest angle if necessary, to en-
sure adequate control, reach and com-
fort. The head restraint should also be
adjusted for proper height. See also the
section on air bags (
page 61) for
proper seat positioning.
In addition, adjust the steering wheel to
ensure adequate control, reach, opera-
tion and comfort. Both the interior and
exterior rear view mirrors should be ad-
justed for adequate rear vision.
Fasten seat belts. Infants and small
children should be seated in a properly
secured restraint system that complies
with U.S. Federal Motor Vehicle Safety
Standards 213 and 225 and Canadian
Motor Vehicle Safety Standards 213
and 210.2.
Warning!
G
Do not activate the memory function while
driving. Activating the memory function
while driving could cause the driver to lose
control of the vehicle.

dard child restraint or less on
the front passenger seat.
The system is malfunctioning.
Make sure there is nothing between seat cushion
and child seat and check installation of the child
seat.
Make sure that no objects applying supplemental
weight onto the seat are present.
If the front passenger front air bag off indicator lamp
remains out, have the system checked as soon as
possible by an authorized Mercedes-Benz Center.
Do not transport a child on the front passenger seat
until the system has been repaired.
Also note any messages in the multifunction display
and follow corrective steps (
