Warning!
G
Always fasten your seat belt before driving
off. Always make sure all of your passengers
are properly restrained, even those sitting in
the rear and pregnant women.
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 vehicle or be
ejected from it. You can be seriously 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.
Warning!
G
Never ride in a moving vehicle with the seat
backrest in an excessively reclined position
as this can be dangerous. You could slide
under the seat belt in a collision. If you slide
under it, the belt would apply force at the ab-
domen or neck. That could cause serious or
even fatal injuries. The seat backrest and
seat belt provide the best restraint when the
wearer is in a nearly upright position and the
belt is properly positioned on the body.Warning!
G
Never let more people ride in the vehicle
than there are seat belts available. Make
sure everyone riding in the vehicle is cor-
rectly restrained with a separate seat belt.
Never use a seat belt for more than one
person at a time.

Warning!
G
Damaged seat belts or belts that were highly
stressed in an accident must be replaced
and their anchoring points must also be
checked.
Only use seat belts which have been
approved by Mercedes-Benz.
Do not make any modifications to the seat
belts. This can lead to unintended activation
of the ETDs or to failure.
Do not bleach or dye seat belts as this may
severely weaken them. In a crash they may
not be able to provide adequate protection.
Have all work carried out only by qualified
technicians. Contact an authorized
Mercedes-Benz Center.
Warning!

USE SEAT BELTS PROPERLY

Seat belts can only work when used
properly. Never wear seat belts in any
other way than as described in this sec-
tion, as that could result in serious inju-
ries in case of an accident.


Each occupant should wear their seat
belt at all times, because seat belts help
reduce the likelihood of and potential
severity of injuries in accidents, includ-
ing rollovers. The integrated restraint
system includes SRS (driver air bag, pas-
senger front air bag, head-thorax air
bags and rear side-impact air bags), ETD
(seat belt emergency tensioning device),
and front seat knee bolsters. The sys-
tem is designed to enhance the protec-
tion offered to properly belted
occupants in certain frontal (front air
bags and ETD) and side (head-thorax
and rear side-impact air bags and ETD)
impacts which exceed preset deploy-
ment thresholds.


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 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 belts over rigid or breakable
objects in or on your clothing, such as
eyeglasses, pens, keys 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.


70 Safety and SecurityOccupant safety
Emergency tensioning device (ETD),
seat belt force limiter
The seat belts are equipped with emergen-
cy tensioning devices and belt force
limiters.
The ETD is designed to activate in the
following cases:

in frontal or rear-end impacts
exceeding a preset severity level


if the restraint systems are operational
and functioning correctly, see
1indicator lamp (
page 60)In an impact, emergency tensioning
devices remove slack from the belts. Belt
force limiters reduce the force exerted by
the seat belts on occupants during a crash.
Automatic comfort-fit feature seat belt
An automatic comfort-fit feature for front
seats reduces the retracting force of the
seat belts when they are in normal use.


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
booster seats, always follow the child
seat manufacturer’s instructions.
!The 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 seats will activate
with or without the respective seat
belts fastened.
Warning!
G
An emergency tensioning device (ETD) that
was activated must be replaced.
When disposing of the emergency tension-
ing device, our safety instructions must be
followed. These are available at your
authorized Mercedes-Benz Center.


72 Safety and SecurityOccupant safetyChildren in the vehicle
If an infant or child is traveling with you in
the vehicle:

Secure the child using an infant or child
restraint appropriate to the age and
size of the child.


Make sure that the infant or child is
properly secured at all times while the
vehicle is in motion.
Infant and child restraint seats and
information on choosing an appropriate
restraint system can be obtained from any
Mercedes-Benz Center.
Infant and child restraint systems
We recommend all infants and children be
properly restrained at all times while the
vehicle is in motion.
All lap-shoulder belts except the driver’s
seat belt have special seat belt retractors
for secure fastening of child restraints.To fasten a child restraint, follow child
restraint instructions for mounting. Then
pull the shoulder belt out completely and
let it retract. During seat belt retraction, a
ratcheting sound can be heard to indicate
that the special seat belt retractor is acti-
vated. The belt is now locked. Push down
on child restraint to take up any slack.
To deactivate, release seat belt buckle and
let seat belt retract completely. The seat
belt can again be used in the usual
manner.

seat anchors (
page 80).
!The use of infant or child restraints is
required by law in all 50 states, the Dis-
trict of Columbia, the U.S. territories,
and all Canadian provinces.
Infants and small children should be
seated in an appropriate infant or child
restraint system, properly secured by a
lap / shoulder belt or, if so equipped, a
lap shoulder belt and a child restraint
lower anchorage system that complies
with U.S. Federal Motor Vehicle Safety
Standards 213 and 225 and Canadian
Motor Vehicle Safety Standards 213
and 210.2.Warning!
G
Never release the seat belt buckle while the
vehicle is in motion, since the special seat
belt retractor will be deactivated.

!
A statement by the child restraint man-
ufacturer of compliance with this stan-
dard can be found on the instruction
label on the restraint and in the instruc-
tion manual provided with the restraint.
When using any infant or child restraint
system, be sure to carefully read and
follow all manufacturer’s instructions
for installation and use.
Please read and observe warning labels
affixed to the inside of the vehicle and
to infant or child restraints.
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 or seat
belt and lower anchors, 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
require 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 OCS senses the weight of a
typical 12-month-old child or less along
with the weight of a standard
appropriate child restraint on the front
passenger 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-fac-
ing 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.


74 Safety and SecurityOccupant safety

If you must install a rear-facing child
restraint on the front passenger seat be-
cause circumstances require you to do
so, make sure that the 56 indi-
cator lamp is illuminated, indicating that
the front passenger front air bag is deac-
tivated. Should the 56 indicator
lamp not illuminate or go out while the
restraint is installed, please check in-
stallation. Periodically check the
56 indicator lamp while driving
to make sure the 56 indicator
lamp is illuminated. If the 56
indicator lamp goes out or remains out,
do not transport a child on the front pas-
senger seat until the system has been
repaired. A child in a rear-facing child re-
straint 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
front air bag may or may not be
activated (
page 76).
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.
Children too big for a toddler restraint must
ride in seats using regular seat belts. Posi-
tion shoulder belt across chest and shoul-
der, not face or neck. A booster seat may be
necessary to achieve proper belt positioning
for children from 41 lbs until they reach a
height where a lap/shoulder belt fits
properly without a booster.


75 Safety and Security
Occupant safety
Occupant Classification System
The O
ccupant C
lassification S
ystem (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
nearly upright position with their back
against the seat backrest and feet on the
floor to be correctly classified. If the occu-
pant's weight is transferred to another
object in the vehicle (e.g. by leaning on
armrests), the OCS may not be able to
properly approximate the occupant’s
weight category. Both driver and the front passenger should
always use the 56 indicator lamp
as an indication of whether or not the front
passenger is properly positioned.
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 chil-
dren in a child restraint system may use
vehicle equipment and may cause an acci-
dent and/or serious personal injury.
iThe system does not deactivate the
head-thorax air bag and the emergency
tensioning device.
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.

77 Safety and Security
Occupant safety
If the 56 indicator lamp is illuminat-
ed, the front passenger front air bag is
deactivated and will not be deployed.
If the 56 indicator lamp is not illumi-
nated, the front passenger front air bag is
activated and will be deployed:

in the event of certain frontal impacts


if impact exceeds a preset deployment
threshold


independently of the head-thorax air
bag and rear side-impact air bags.
If the front passenger front air bag is de-
ployed, the rate of inflation will be influ-
enced 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).
