82 Safety and Security
Occupant safety
If you place a child in a forward-facing
child restraint on the passenger seat,
move the seat as far back as possible,
use the proper child restraint recom-
mended for the age, size and weight of
the child, and secure child restraint with
the vehicle’s seat belt according to the
child seat manufacturer’s instructions.
For children larger than the typical
12-month-old child, the passenger front
air bag may or may not be activated
(
page 72).
Warning!G
Infants and small children should never
share a seat belt with another occupant.
During an accident, they could be crushed
between the occupant and seat belt.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle
and/or the child is not properly secured in
the child restraint.
Warning!G
Children too big for a toddler restraint must
ride in seats using regular seat belts.
Position the shoulder belt across chest and
shoulder, not face or neck. A booster seat
may be necessary to achieve proper seat
belt positioning for children over 41 lbs until
they reach a height where a lap/shoulder
belt fits properly without a booster.
When the child restraint is not in use,
remove it from the vehicle or secure it with
the seat belt to prevent the child restraint
from becoming a projectile in the event of
an accident.
Do not leave children unattended in the
vehicle, even if the children are secured in a
child restraint system. Unsupervised
children in a child restraint system may use
vehicle equipment and may cause an
accident and/or serious personal injury.

Memory function*
Memory function*
Prior to operating the vehicle, the driver
should check and adjust the seat height,
seat position fore and aft, and seat back-
rest angle if necessary, to ensure adequate
control, reach and comfort. The head re-
straint should also be adjusted for proper
height. See also the section on air bags
(
page 66) for proper seat positioning.
In addition, adjust the steering wheel to
ensure adequate control, reach, operation
and comfort. Both the interior and exterior
rear view mirrors should be adjusted for
adequate rear vision.
Fasten seat belts. Infants and small
children should be seated in an appropri-
ate infant or child restraint system which is
properly secured by a lap-shoulder belt
and that complies with U.S. Federal Motor
Vehicle Safety Standards 213 and 255
and Canadian Motor Vehicle Safety
Standards 213 and 210.2.With the memory function you can store up
to three different configurations.
Each store position on the driver’s side
includes the following settings:
Seat position
Steering wheel position
Exterior rear view mirrors’ position
Each store position on the passenger side
includes the following setting:

75The front passenger front air bag
off indicator lamp does not illumi-
nate and/or does not remain illu-
minated with the weight of a
typical 12-month-old child in a
standard child restraint or less on
the 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
passenger seat until the system has
been repaired.
Also read and observe any messages
in the multifunction display and follow
corrective steps (
page 361).

Front passenger
airbag enabled
See Operator’s
ManualThe passenger front air bag and the
passenger-side knee bag are
activated while driving even though a
child, small individual, or object below
the system’s weight threshold is on
the passenger seat, or the passenger
seat is empty. Objects on the seat or
forces acting on the seat may make
the system sense supplemental
weight.Stop the vehicle in a safe location as soon as possible and check the
passenger seat for the following:
Switch off the ignition (page 37).
Apply the parking brake (page 59).
Remove child and child restraint from passenger seat.
Make sure that no objects which are applying supplemental weight
onto the seat are present. The system may recognize such supple-
mental weight and sense that an occupant on the passenger seat is
of a greater weight than actually present.
Keep the seat unoccupied, close the passenger door and switch on
the ignition (
page 37).
Monitor the 75indicator lamp on the center console
(
page 29) and the multifunction display in the instrument cluster
(
