43 Safety and Security
Occupant safety
Occupants, especially children, should
always sit as upright as possible, proper-
ly use the seat belts and use an appro-
priately sized infant restraint, toddler
restraint, or booster seat recommended
for the size and weight of the child.
Failure to follow these instructions can
result in severe injuries to you or other
occupants.
If you sell your vehicle, it is important that
you make the buyer aware of this safety
information. Be sure to give the buyer this
Operator’s Manual.Warning!G
Accident research shows that the safest
place for children in an automobile is in the
rear seat.
There is a possibility for a side impact air
bag related injury if occupants, especially
children, are not properly seated or re-
strained when next to a side impact air bag
which needs to deploy rapidly in a side im-
pact in order to do its job.
To help avoid the possibility of injury, please
follow these guidelines:
(1) Always sit as upright as possible, prop-
erly use the seat belts, and for all chil-
dren 12 years old and under, use an
appropriately sized infant restraint, tod-
dler restraint, or booster seat recom-
mended for the size and weight of the
child.
(2) Always wear seat belts properly.
iAir bags are designed to deploy only in cer-
tain frontal impacts (front air bags), and in side
impacts (side impact and window curtain air
bags) which exceed preset thresholds, and in
certain rollovers (window curtain air bags). Only
during these events will they provide their sup-
plemental protection.
The driver and passengers should always wear
their seat belts. Otherwise it is not possible for
air bags to provide their supplemental protec-
tion.
In case of other types of impacts and impacts be-
low air bag deployment thresholds, air bags will
not deploy. The driver and passenger will then be
protected to the extent possible by a properly
fastened seat belt. A properly fastened seat belt
is also needed to provide the best possible pro-
tection in a rollover.
We caution you not to rely on the presence of the
air bags in order to avoid wearing your seat belt.
It is important to your safety and that of your pas-
sengers that you replace deployed air bags and
repair any malfunctioning air bags to make sure
the vehicle will continue to provide supplemental
crash protection for occupants.

Occupant safety
When you sell your vehicle we strongly
urge you to give notice to the subsequent
owner that it is equipped with an SRS by
alerting them to the applicable section in
the Operator’s Manual.Front air bags
1Driver air bag
2Front passenger front air bag
Driver and front passenger front air bags
are deployed:
in the event of certain frontal impacts
if impact exceeds a preset deployment
threshold
independently of the side impact air
bagsThe air bags will not deploy in impacts
which do not exceed the system’s deploy-
ment thresholds. You will then be protec-
ted by the fastened seat belts.
Given the considerable deployment
speed, required inflation volume, and
the textile structure of the air bags,
there is the possibility of abrasions or
other, potentially more serious injuries
resulting from air bag deployment.
Warning!G
Only use seat covers which have been
tested and approved by Mercedes-Benz for
your vehicle model. Using other seat covers
may interfere with or prevent the
deployment of the front side impact air bags
or the rear side impact air bags. Contact an
authorized Mercedes-Benz Center for avail-
ability.
iThe front air bags in this vehicle have been
designed to inflate in two stages. This allows the
air bag to have different rates of inflation that are
based on the rate of relevant vehicle decelera-
tion as assessed by the air bag control unit.
On the front passenger-side, the front air bag de-
ployment is additionally influenced by the pas-
senger’s weight category as identified by the
Occupant Classification System (OCS)
(
page 47).
The lighter the front passenger-side occupant,
the higher the vehicle deceleration rate required
for the second stage inflation of the air bag.

The passenger front air bag will only be
deployed if:
the system, based on OCS weight sen-
sor readings, senses that the front
passenger seat is occupied
the 59indicator lamp in
the center console is not lit

Side impact air bags
1Front side impact air bag
2Rear side impact air bagThe side impact air bags are deployed:
in impacts exceeding a preset deploy-
ment threshold
on the impacted side of the vehicle
independently of the front air bags
The front passenger side impact air bag1
will not deploy if the OCS senses that the
front passenger seat is empty and the front
passenger seat belt is not fastened (latch
plate is not inserted into the buckle). With
an empty front passenger seat and the
seat belt fastened (latch plate properly in-
serted into buckle) the front passenger
side impact air bag will deploy regardless
of the empty seat.
The side impact air bags are not deployed
in impacts which do not exceed the sys-
tem’s deployment threshold.Window curtain air bags
1Window curtain air bag
The side window curtain air bags are de-
ployed:
in impacts exceeding a preset deploy-
ment threshold
on the impacted side of the vehicle
independently of the front air bags
in certain vehicle rollovers
The side window curtain air bags are not
deployed in impacts which do not exceed
the system’s deployment threshold.

The window curtain air bags fill up the area
indicated by the arrows.
Occupant Classification System
The Occupant Classification System (OCS)
automatically turns the front passenger
front air bag on or off based on the classi-
fied occupant weight category determined
by weight sensor readings from the front
passenger seat.
Occupants must sit properly belted in a po-
sition that is as upright as possible with
their back against the seat backrest and
feet on the floor to be correctly classified.
If the occupant’s weight is transferred to
another object in the vehicle (e.g. by lean-
ing on armrests), the OCS may not be able
to properly approximate the occupant’s
weight category.Furthermore, the occupant weight may ap-
pear to increase or decrease due to
objects hanging on the seat, other passen-
gers pushing on the seat, objects lodged
underneath the seat or stuffed between
seat and middle console or between seat
and door or due to objects applying pres-
sure on the back of the seat. Always make
sure that the seat has clearance in all
directions at all times.
Both driver and the front passenger should
always use the 59indicator
lamp as an indication of whether or not the
front passenger is properly positioned.
iThe system does not deactivate the front
passenger side impact air bag, the window cur-
tain air bag and the emergency tensioning de-
vice.
iIf your seat, including your trim cover and
cushion needs to be serviced in any way, take
the vehicle to an authorized Mercedes-Benz
Center.
Only seat accessories approved by
Mercedes-Benz may be used.
Warning!G
If the 59indicator lamp illumi-
nates when an adult or someone larger than
a small individual is in the front passenger
seat, have the front passenger re-position
himself or herself in the seat until the
59indicator lamp goes out, or
check whether objects are caught under or
around the seat.
More information about air bag display mes-
sages (
page 618).
In the event of a collision, the air bag control
unit will not allow front passenger front air
bag deployment when the OCS classified
the front passenger seat occupant as being
up to or less than the weight of a typical
12-month-old child in a standard child re-
straint or if the front passenger seat is
sensed as being empty.

Occupant safety
When the OCS senses that the front passen-
ger seat occupant is classified as being up
to or less than the weight of a typical
12-month-old child in a standard child
restraint, the 59indicator
lamp will illuminate when the engine is start-
ed and remain illuminated, indicating that
the front passenger front air bag is deacti-
vated.
When the OCS senses that the front passen-
ger seat is classified as being empty, the
59indicator lamp will illumi-
nate when the engine is started and remain
illuminated, indicating that the front
passenger front air bag is deactivated.
When the OCS senses that the front passen-
ger seat occupant is classified as being
heavier than the weight of a typical
12-month-old child seated in a standard
child restraint or as being a small individual
(such as a young teenager or a small adult),
the 59indicator lamp will illu-
minate for approximately 6 seconds when
the engine is started and then, depending on
occupant weight sensor readings fromthe seat, remain illuminated or go out. With
the 59indicator lamp illumi-
nated, the front passenger front air bag is
deactivated. With the 59 indi-
cator lamp out, the front passenger front air
bag is activated.

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.
Page 50 of 761
49 Safety and Security
Occupant safety
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.
If the 59indicator lamp
goes out or remains out, do not trans-
port a child on the front passenger seat
until the system has been repaired. 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.
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
front air bag may or may not be
activated (
page 48).

instrument cluster.
1Front passenger front air bag indicator
lamp
The 59indicator lamp1 will
be illuminated, except with the SmartKey
removed from the starter switch or with
the starter switch in position0
(
page 346).
iDeployment of the driver front air bag does
not mean that the front passenger front air bag
also should have deployed.
The Occupant Classification System (
page 47)
may have determined:
that the seat was empty or occupied by the
weight up to or less than that of a typical
12-month-old child seated in a standard
child restraint – both instances where the
system suppresses deployment of the front
passenger front air bag even though the im-
pact met the criteria and was of sufficient
severity to deploy the driver front air bag.
that the seat was occupied by a small individ-
ual (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
standard child restraint – instances where
the system may suppress deployment of the
front passenger front air bag even though
the impact met the criteria and was of suffi-
cient severity to deploy the driver front air
bag.
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.

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 346), the 59
indicator lamp1 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 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.For more information, see the “Practical
hints” section (
page 610).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 Cen-
ter.
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 contact an authorized
Mercedes-Benz Center before seating any
child on the front passenger seat.
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.

To deactivate, release seat belt buckle and
let seat belt retract completely. To deacti-
vate the special seat belt retractor for the
front passenger seat, the front passenger
seat must be in the most backward posi-
tion. The seat belt can again be used in the
usual manner.
The use of infant or child restraints is re-
quired by law in all 50 states, the District
of Columbia, the U.S. territories and all Ca-
nadian provinces.Infants and small children should be seat-
ed in an appropriate infant or child re-
straint system properly secured in
accordance with the manufacturer’s in-
structions for the child restraint, that com-
plies with U.S. Federal Motor Vehicle
Safety Standards 213 and 225 and Canadi-
an Motor Vehicle Safety Standards 213
and 210.2.
A statement by the child restraint manu-
facturer of compliance with these stan-
dards can be found on the instruction label
on the restraint and in the instruction man-
ual provided with the restraint.
When using any infant or child restraint
system, make sure to carefully read and
follow all manufacturer’s instructions for
installation and use.
Please read and observe warning labels af-
fixed to the inside of the vehicle and to
infant or child restraints.
Warning!G
Never release the seat belt buckle while the
vehicle is in motion, since the special seat
belt retractor will be deactivated.

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
appropriately sized infant restraint, toddler
restraint, or booster seat recommended for
the size and weight of the child.
