49 Safety and Security
Occupant safety
independently of the side impact air
bags
If the front passenger air bag is deployed,
the rate of inflation will be influenced by:
the rate of relevant vehicle deceleration
as assessed by the air bag control unit
front passenger’s weight category as
identified by the Occupant Classification
System (OCS).
Warning!G
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front seat-
ing position. Thus, we strongly recommend
that children be placed in the rear seats
whenever possible. Regardless of seating
position, children 12 years old and under
must be seated and properly secured in an
appropriate infant or child restraint
recommended for the size and weight of the
child.
The infant or child restraint must be properly
secured with the vehicle’s seat belt, the seat
belt and top tether strap, or lower anchors
and top tether strap, fully in accordance
with the child seat manufacturer’s
instructions.
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
passenger front air bag inflates in a
collision which could occur under some
circumstances, even with the air bag
technology 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
restraint on the front passenger seat
because circumstances require you to
do so, make sure that the
59 indicator lamp is illumi-
nated, indicating that the front passen-
ger front air bag is deactivated. Should
the 59 indicator lamp not
illuminate or go out while the restraint is
installed, please check installation. Peri-
odically check the 59 indi-
cator lamp while driving to make sure
the 59 indicator lamp is il-
luminated.
51 Safety and Security
Occupant safety
Self-test Occupant Classification
System
After turning the SmartKey in the starter
switch to position1 or2 or pressing the
KEYLESS-GO* start/stop button once or
twice (
page 337), the 59
indicator lamp1 located in the dash-
board illuminates. If an adult occupant is
properly sitting on the front passenger
seat and the system senses the occupant
as being an adult, the 59 indi-
cator lamp will illuminate and go out after
approximately 6 seconds.
If the seat is not occupied and the system
senses the front passenger seat as being
empty, the 59indicator lamp
will illuminate and not go out.
Warning!G
If the =indicator lamp and the
59 indicator lamp are lit at the
same time, there is a malfunction in the
Occupant Classification System. The front
passenger 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.
Contact an authorized Mercedes-Benz
Center.
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
approximate the occupant weight
category.
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 position that is
as upright as possible 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
Center.
Read and observe all warnings in this
chapter.
Warning!G
If the 59 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.

hints” section (
page 578).
Seat belts
The use of seat belts and infant and child
restraint systems is required by law in all
50 states, the District of Columbia, the
U.S. territories and all Canadian provinces.
Even where this is not the case, all vehicle
occupants should have their seat belts fas-
tened whenever the vehicle is in motion.
For more information, see “Fastening the
seat belts” (
page 360).
Warning!G
Never place anything between seat cushion
(e.g. pillow), since it reduces the effective-
ness of the Occupant Classification 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 protection for the
child.
Follow the manufacturer’s instructions for
installation of child seats.
iFor information on infants and children trav-
eling with you in the vehicle and restraint sys-
tems for infants and children, see “Children in
the vehicle” (
page 57).
Warning!G
Always fasten your seat belt before driving
off. Always make sure all of your passengers
are properly restrained, including those sit-
ting in the rear.
Failure to wear and properly fasten and po-
sition your seat belt greatly increases your
risk of injuries and their likely severity in an
accident. You and your passengers should
always wear seat belts.
If you are ever in an accident, your injuries
can be considerably more severe without
your seat belt properly buckled.
Without your seat belt buckled, you are
much more likely to hit the interior of the ve-
hicle or be ejected from it. You can be seri-
ously injured or killed.
In the same crash, the possibility of injury or
death is lessened if you are properly wearing
your seat belt. Air bags can only protect as
they are designed if the occupants are prop-
erly wearing their seat belts.

Occupant safety
Enhanced seat belt reminder system
When the engine is started, the seat belt
telltale< will always illuminate
for 6 seconds to remind you and your
passengers to fasten your seat belts.
If the driver’s seat belt is not fastened
when the engine is started, an additional
warning chime will also sound for a
maximum of 6 seconds or until the driver’s
seat belt is fastened.
If after these 6 seconds the driver’s or the
front passenger’s seat belt (with the front
passenger seat occupied) is not fastened
with both doors closed,
the seat belt telltale< remains
illuminated for as long as either the
driver’s or front passenger’s seat belt is
not fastened.
and if the vehicle speed once exceeds
15 mph (25 km/h), the seat belt
telltale< starts flashing and a
warning chime sounds with increasing
intensity for a maximum of 60 seconds
or until the driver’s and the
which exceed preset deployment
thresholds and in certain rollovers (win-
dow curtain air bags and ETD).
Never wear the shoulder belt under your
arm, against your neck or off your shoul-
der. In a frontal crash, your body would
move too far forward. That would in-
crease the chance of head and neck in-
juries. The seat belt would also apply too
much force to the ribs or abdomen,
which could severely injure internal or-
gans such as your liver or spleen.
Never wear seat 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-
m e n . I f t h e s e a t b e l t i s p o s i t i o n e d a c r o s s
your abdomen, it could cause serious in-
juries in a crash.
Never use a seat belt for more than one
person at time. Do not fasten a seat belt
around a person and another person or
other objects.
Seat belts should not be worn twisted.
In a crash, you wouldn’t have the full
width of the seat belt to distribute im-
pact forces. The twisted seat belt
against your body could cause injuries.
Pregnant women should also always 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
booster seats, always follow the child
seat manufacturer’s instructions.
55 Safety and Security
Occupant safety
front passenger’s seat belt are fas-
tened. If you and/or your passenger re-
lease the seat belt during driving, the
seat belt telltale< starts flashing
and the warning chime sounds as de-
scribed before.
If the driver’s or the front passenger’s
seat belt remains unfastened after
60 seconds, the warning chime stops
sounding, the seat belt telltale<
stops flashing but continues to be illu-
minated.
After a vehicle standstill the warning
chime is reactivated and the seat belt
telltale< is flashing again if the ve-
hicle speed once exceeds 15 mph
(25 km/h).
The seat belt telltale< will only go out
if both the driver’s and the front passen-
ger’s seat belt (with the front passenger
seat occupied) are fastened, or the vehicle
is standing still and a door is opened.
For more information, see “Practical hints”
(
page 573).Emergency Tensioning Device (ETD),
seat belt force limiter
The seat belts for the front and rear seats
are equipped with emergency tensioning
devices and seat belt force limiters.
The ETD is designed to activate in the
following cases:
in frontal or rear-end impacts exceed-
ing the system deployment threshold
in certain vehicle rollovers
if the restraint systems are operational
and functioning correctly,
see=indicator lamp (
page 575)
In an impact, emergency tensioning
devices remove slack from the seat belts in
such a way that the seat belts fit more
snugly against the body. Seat belt force limiters, when activated, are employed to
help reduce the peak force exerted by the
seat belts on occupants during a crash.
Automatic comfort-fit feature seat belt
An automatic comfort-fit feature for the
front seats reduces the retracting force of
the seat belts when they are in normal use.
iThe ETDs for the front seats will only acti-
vate if the front seat belt is fastened (latch plate
properly inserted into buckle).
The ETDs for the rear seats will activate with or
without the respective seat belt fastened.
Warning!G
A pyrotechnic Emergency Tensioning Device
(ETD) that was activated must be replaced.
When disposing of the pyrotechnic emer-
gency tensioning device, our safety instruc-
tions must be followed. These are available
at your authorized Mercedes-Benz Center.
