SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you and
lock the vehicle. Do not leave children unat-

70 Safety and SecurityOccupant safety
Emergency tensioning device (ETD),
seat belt force limiter
The seat belts for the front and rear outer
seats are equipped with emergency ten-
sioning devices and belt force limiters.
The ETD is designed to activate in the fol-
lowing cases:
in frontal or rear-end impacts exceed-
ing a preset severity level
in certain vehicle rollovers
if the restraint systems are operational
and functioning correctly, see
1indicator lamp (
page 60)
Never wear belts over rigid or breakable
objects in or on your clothing, such as
eyeglasses, pens, SmartKeys etc., as
these might cause injuries.
Position the lap belt as low as possible
on your hips and not across the abdo-
men. If the belt is positioned across your
abdomen, it could cause serious injuries
in a crash.
Never use a seat belt for more than one
person at a time. Do not fasten a seat
belt around a person and another per-
son or other objects.
Belts should not be worn twisted. In a
crash, you wouldn’t have the full width
of the belt to distribute impact forces.
The twisted belt against your body could
cause injuries.
Pregnant women should also use a
lap-shoulder belt. The lap belt portion
should be positioned as low as possible
on the hips to avoid any possible pres-
sure on the abdomen.
Never place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.
When using a seat belt to secure infant
or toddler restraints or children in boost-
er seats, always follow the child seat
manufacturer's instructions.
iThe ETDs for the front seats will only
activate if the front seat belts are fas-
tened (latch plate properly inserted
into buckle).
The ETDs for the rear outer seats will
activate with or without the respective
seat belts fastened.
78 Safety and SecurityOccupant safety
The 75 indicator lamp is located
in the center console.
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.
79 Safety and Security
Occupant safety
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.
