77 Safety and Security
Occupant safety
Children can be killed or seriously injured by
an inflating air bag. Note the following im-
portant information when circumstances re-
quire you to place a child in the front
passenger seat:
Your vehicle is equipped with air bag
technology designed to turn off the front
passenger front air bag in your vehicle
when the system senses the weight of a
typical 12-month-old child or less along
with the weight of a standard appropri-
ate child restraint on the front passen-
ger seat.
A child in a rear-facing child restraint on
the front passenger seat will be serious-
ly injured or even killed if the front pas-
senger front air bag inflates in a collision
which could occur under some circum-
stances, even with the air bag technolo-
gy installed in your vehicle. The only
means to completely eliminate this risk
is to never place a child in a rear-facing
child restraint in the front seat. We
therefore strongly recommend that you
always place a child in a rear-facing
child restraint in the back seat.
If you must install a rear-facing child re-
straint on the front passenger seat be-
cause circumstances require you to do
so, make sure that the 75 in-
dicator lamp is illuminated, indicating
that the front passenger air bag is deac-
tivated. Should the light not illuminate
or go out while the restraint is installed,
please check installation. Periodically
check the indicator lamp while driving to
make sure the lamp is illuminated. If the
75 indicator lamp goes out or
remains out, do not transport a child on
the front passenger seat until the sys-
tem has been repaired. A child in a
rear-facing child restraint on the front
passenger seat will be seriously injured
or even killed if the front passenger front
air bag inflates.
If you have to place a child in a
forward-facing child restraint on the
front passenger seat, move the seat as
far back as possible, use the proper
child restraint recommended for the
age, size and weight of the child, and se-
cure 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 front passenger
air bag may or may not be activated
(page 76).

The 75 indicator lamp is located

1Indicator lampThe 75 indicator lamp1 will be
illuminated, except with the SmartKey re-
moved or in starter switch position0.
iDeployment of the driver front air bag
does not mean that the front passenger
front air bag also should have de-
ployed.
The Occupant Classification System
(page 74) may have determined:
that the seat was empty or occu-
p i e d b y t h e w e i g h t u p t o o r l e s s t h a n
that of a typical 12-month-old child
seated in a standard child restraint
- both instances where the system
suppresses deployment of the pas-
senger front air bag even though
the impact met the criteria and was
of sufficient severity to deploy the
driver front air bag.
that the seat was occupied by a
small individual (such as a young
teenager or a small adult) or a child
weighing more than the weight of a
typical 12-month-old child in a stan-
dard child restraint - instances
where the system may suppress de-
ployment of the passenger front
air bag even though the impact met
the criteria and was of sufficient se-
verity to deploy the driver front
air bag.
Warning!
G
If the 1indicator lamp and the
75 indicator lamp are lit at the
same time, there is a malfunction in the Oc-
cupant Classification System. The front pas-
senger front air bag will be deactivated in
this case.
In order to ensure proper operation of the
air bag system and OCS:
Have the system checked as soon as
possible by qualified technicians. Con-
tact an authorized Mercedes-Benz Cen-
ter.
Do not place more than 4.4 lbs (2 kg)
into the ruffled storage bag on the back
of the front passenger seat. Otherwise,
the OCS may not be able to properly ap-
proximate the occupant weight catego-
ry.

Self-test Occupant Classification Sys-
tem
After turning the SmartKey in the starter
switch to position1 or2 or pressing the
KEYLESS-GO* start/stop button once or
twice, the 75 indicator lamp1
located in the center console illuminates. If
an adult occupant is properly sitting on the
front passenger seat and the system sens-
es the occupant as being an adult, the
75 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 75 indicator lamp will
illuminate and not go out. For more information, see the “Practical
hints” section (
page 374).
Do not place objects under and / or
around the front passenger seat.
Do not hang anything from or attach any
items to the seats.
Do not stuff objects such as books be-
tween the middle console and the front
passenger seat.
Do not move the front passenger seat
backwards against stiff objects.
Sit properly belted in a nearly upright
position with your back against the seat
backrest.
Do not lean on the armrests or lift your-
self from the seat by using the handle
over the door as this may cause the OCS
to be unable to correctly approximate
the occupant weight category.
Only have the seat repaired or replaced
by an authorized Mercedes-Benz Cen-
ter.
Read and observe all warnings in this
chapter.
Warning!
G
If the 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.

Children too big for a toddler restraint must
ride in seats using regular seat belts. Posi-
tion shoulder belt across chest and shoul-

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.

er’s instructions.
