Special child restraint systems which are
compatible with BabySmart™ are necessary
for deactivating the front-passenger air bag.
When the special BabySmart™-compatible
child restraint system is installed correctly
and is recognized
by
the sensor system in the
front-passenger seat, the front-passenger air
bag is deactivated. In this case, 00730074
indicator lamp 0043 lights up. If you have any
questions regarding the special BabySmart™-
compatible child restraint systems, consult
an authorized Mercedes-Benz Center.

Important safety notes G
WARNING
Do not secure any objects (e.g. coat hangers)
on the NECK-PRO head
restraints. Otherwise,
the NECK-PRO head restraints may not
function properly, or in the event of a rear-end
collision may not be able offer the level of
protection they are designed to provide. G
WARNING
Head restraint covers prevent the NECK-PRO
head restraints from triggering correctly.
Consequently, the NECK-PRO head
restraints cannot provide the intended level of
protection. Do not
use
head restraint covers. G
WARNING
For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint
so that it is as close
to the head as possible and the center of the
head restraint supports the back of the head
at eye level. This will reduce the potential for
injury to the head and neck in the event of an
accident or similar situation.

G
WARNING
Never let more people ride in the vehicle than
there are seat belts available. Make sure
everyone riding in the vehicle is correctly
restrained with a separate seat belt. Never
use a seat belt
for more than one person at a
time. G
WARNING
Always have damaged seat belts or seat belts
that have been subjected to a load in an
accident replaced and the anchorages
checked.
Only use seat belts that have been approved
by Mercedes-Benz.
Never tamper with seat belts. This can result
in the unintended deployment of the
Emergency Tensioning Devices or the failure
to deploy when necessary.
Do not bleach or dye seat belts, as this may
severely weaken them. In the event of a
collision, they may be unable to provide
adequate protection.
Have all work carried out only by qualified
technicians. Consult a qualified specialist
workshop.
The use of infant
or child restraints is required
by law in all 50 states, the District of
Columbia, all U.S. territories and all Canadian
provinces.
Even where this is not the case, all vehicle
occupants should have their seat belts
fastened when the vehicle is in motion.
i See "Children in the vehicle"
(Y page 54) for further information on
infants and children traveling in the vehicle,
as well as on child restraint systems. Correct use of the seat belts G
WARNING
CORRECT USE OF SEAT BELTS
R Seat belts only work properly if they are
fastened correctly. Never wear
seat belts in
any other way than as described in this
section, as that could result in serious
injuries in the event of an accident.
R All occupants should wear their seat belt at
all times, because seat belts help reduce
the likelihood of and potential severity of
injuries in accidents, even if the vehicle
overturns. The restraint system installed is
equipped with SRS (driver's air bag, front-
passenger air bag, window curtain air
bags), belt tensioners and belt force
limiters.
The system is designed to enhance the
protection offered to occupants who are
wearing their seat belts correctly, in certain
frontal impacts (front air bags and belt
tensioners) and side impacts (window
curtain air bags and belt tensioners) which
exceed preset deployment thresholds.
R Never route the shoulder section of the
seat belt under your arm, across your neck
or anywhere other than across your
shoulder. In the event of a frontal impact,
your body would be moved too far forward.
This would increase the risk of head and
neck injuries. The seat belt would then
apply excessive force to the ribs or
abdomen which could cause severe
internal injuries to organs such as the liver
or spleen.
Adjust the seat belt so that the upper part
of the belt is as close as possible to the
center of the shoulder. It should not touch
the neck. Never route the belt under the
shoulder. The height of the belt outlet can
be altered to ensure correct usage.
R The lap belt should be routed as low as
possible across the hips, not across the
abdomen. If the lap belt is routed across the Occupant safety
49
Safety
Z
abdomen, it could cause serious injuries in
the event of an impact.
R Never route the seat belt over rigid or
fragile objects in or on your clothing, such
as eyeglasses, pens, keys
etc, as this could
cause injuries.
R Always ensure that the seat belt is routed
correctly. This is particularly important if
you are wearing loose clothing.
R Only one person should use each seat belt
at any one time. Never use a seat belt to
restrain more than one person or route the
belt around additional objects.
R Never wear seat belts when they are
twisted. Otherwise, in the event of an
impact, the full width of the seat belt is
unavailable to distribute the force of the
impact. The twisted seat belt routed across
your body could cause injuries.
R Pregnant women should also wear a three-
point seat belt. The lap belt must always
pass across your lap as low down as
possible, i.e. across your hips; not across
your abdomen.
R The seat backrest should be set as close to
vertical as possible.
R Check the seat belt during the journey in
order to make sure that it is correctly
positioned.
R Never rest your feet on the dashboard or
the seat. Always keep both feet on the floor
in front of the seat.
R When using a seat belt to secure an infant
restraint system, child restraint system or
a child on a booster seat, always follow the
child seat manufacturer's instructions. G
WARNING
Do not pass seat belts over sharp edges. They
could tear.
Do not allow the
seat belt to get caught in the
door or in the seat adjustment mechanism.
This could damage the seat belt. Never attempt to make modifications to seat
belts. This could impair the effectiveness of
the seat belts.

WARNING
According to accident statistics, children are
safer when properly restrained on the rear
seats than on the
front-passenger seat. Thus,
we strongly recommend that children be
placed in the rear seat whenever possible.
Regardless of seating position, children 12
years old and under must be seated and
properly secured in an appropriately sized
child restraint system or booster seat
recommended for the size and weight of the
child. For additional information, see the
"Children in the vehicle" section.
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. G
WARNING
Children 12 years old and under must never
ride in the front seat, except in a Mercedes-
Benz authorized BabySmart™ compatible
child seat, which operates with the
BabySmart™ system installed in the vehicle
to deactivate the
front
passenger front air bag
when it is installed properly. Otherwise they
will be struck by the air bag when it inflates in
a crash. If this happens, serious or fatal injury
will result. 50

If the front-passenger seat is not
occupied, do not engage the seat belt
tongue in the buckle on the front-

Emergency
Tensioning Device could be triggered in the
event of an accident.
X In order to ensure that the pyrotechnic
Emergency Tensioning Devices have not
been triggered, always have the seat belts
checked after an accident.
If the Emergency Tensioning Devices have
been triggered, they must be replaced.
The seat belts for the front seats and rear
outer seats are equipped
with ETDs and seat
belt force limiters.
The ETDs on the driver's and front-passenger
seat consist of pyrotechnic belt buckle
tensioners and belt anchor installation
tensioners that are triggered together. The
belt buckle tensioner is mounted on the B-
pillar and the belt anchor installation is
mounted on the side of the seat. After
deploying, both tensioners must always be
replaced.
The ETDs tighten the seat belts in an accident,
pulling them close against the body.
The ETDs do not correct incorrect seat
positions or incorrectly fastened seat belts.
The ETDs do not pull vehicle occupants back
towards the backrest.
When triggered, seat belt force limiters help
to reduce the peak force exerted by the seat
belt on the vehicle occupant.
The front seat belt force limiters are
synchronized with the front air bags, which
take on a part of the deceleration force. Thus,
the force exerted on the occupant is
distributed over a greater area.
The ETDs can only be activated when:
R the SmartKey is in position 1 or 2 in the
ignition lock.
R the restraint systems are operational; see
"SRS warning lamp" ( Y page 39). R

of an accident, if:
R in the event of a head-on or rear-end
collision, the vehicle decelerates or
accelerates rapidly in a longitudinal
direction during the initial stages of the
impact
R if, in the event of a side impact, on the side
opposite the impact the vehicle
decelerates or accelerates rapidly in a
lateral direction
R in certain situations where the vehicle
overturns and the system determines that
it can provide additional protection
If the ETDs are deployed, you will hear a bang,
and a small amount of powder may also be
released. Only in rare cases will the bang
affect your hearing. The powder that is

Important safety notes G
WARNING
According to accident statistics, children are
safer when properly restrained in the rear
seating positions than in the front seating
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 restraint, toddler restraint, or booster
seat recommended for the size and weight of
the child. 54
Children in the vehicle
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.
Occupants, especially children, should always
sit as upright as possible, wear the seat belt
properly and use an appropriately sized infant
restraint, toddler restraint, or booster seat
recommended for the size and weight of the
child.
Children can be killed or seriously injured by
an inflating air bag. Note the following
important information when circumstances
require you to place a child in the front
passenger seat:
R Children 12 years old and under must never
ride in the front seat, except in a Mercedes-
Benz authorized BabySmart™ compatible
child seat, which operates with the
BabySmart™ system installed in the vehicle
to deactivate the front passenger front air
bag when it is installed properly. Otherwise
they will be struck by the air bag when it
inflates in a crash. If this happens, serious
or fatal injury will result.
R 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 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 a backseat.
R If you must install a rear-facing child
restraint on the front passenger seat
because circumstances require you to do
so, make sure the 0073 007C indicator
lamp is illuminated, indicating that the front
passenger front air bag is deactivated.
Should the 0073 007C indicator lamp not
illuminate or go out while the restraint is installed, please check installation.
Periodically check the
0073 007C
indicator
lamp while driving to make sure the
0073 007C indicator lamp is illuminated. If
the 0073 007C indicator lamp goes out or
remains out, do not transport 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 seriously
injured or even killed if the front passenger
front air bag inflates.
R 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 secure child restraint with
the vehicle's seat belt according to the
child seat manufacturer's instructions. G
WARNING
Infants and small children should never share
a seat belt with
another occupant. In the event
of 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 that are too large for a child restraint
must travel in seats using normal seat belts.
Position the shoulder belt across the chest
and shoulder, not face or neck. A booster seat
may be necessary to achieve proper seat belt
positioning for children over 41 lb (18 kg) until
they reach a height where a lap-shoulder belt
fits properly without a booster.
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. Children in the vehicle

the SmartKey with you and lock the vehicle.
Do not leave children unattended in the
vehicle, even if they are secured in a child
restraint system, or with access to an
unlocked vehicle. A child's unsupervised
access to a vehicle
could result in an accident
and/or serious personal injury. The children
could:
R injure themselves on parts of the vehicle
R be seriously or fatally injured through
excessive exposure to extreme heat or cold
R injure themselves or cause an accident with
vehicle equipment that can be operated
even if the SmartKey is removed from the
ignition lock or removed from the vehicle,
such as seat adjustment, steering wheel
adjustment, or the memory function
If children open a door, they could injure other
persons or get out of the vehicle and injure
themselves or be injured by following traffic.
Do not expose the child restraint system to
direct sunlight. The child restraint system's
metal parts, for example, could become very
hot, and the child could be burned on these
parts. G
