of the vehicle occupants on the side of
the vehicle on which the impact occurs.
Window curtain air bags 0043 are integrated
into the side of the roof frame and deploy in
the area extending from the front door (A-
pillar) to the rear door (C-pillar).
Window curtain air bags 0043 are deployed:
R on the side on which an impact occurs
R at the start of an accident with a high rate
of lateral vehicle deceleration or
acceleration, e.g. in a side impact
R regardless of whether the front-passenger
seat is occupied
R independently of seat belt use
R if the vehicle rolls over and the system
determines that window curtain air bag
deployment can offer additional protection
to that provided by the seat belt
R independently of the front air bags Window curtain air bags will not deploy in
impacts which do not exceed the system's
preset deployment thresholds for lateral
acceleration/deceleration. You will then be
protected by the fastened seat belt.
BabySmart™ air bag deactivation
system
How the air bag deactivation system
works 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.
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 air44

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 BabySmart™
compatible 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
When using a BabySmart™ compatible child
seat on the front passenger seat, the front
passenger front air bag

will not deploy only if
the 0073 007C indicator lamp remains
illuminated.
Please be sure to check the 0073 007C
indicator lamp every time you use a
BabySmart™ compatible child seat on the
front passenger seat. Should the 0073 007C
indicator lamp go out while the restraint is
installed, please check installation. If the
0073 007C indicator lamp remains out, do not
use the BabySmart™ restraint to transport a
child on the front passenger seat until the
system has been repaired. G
WARNING
The BabySmart™ air bag disabling system
ONLY works with specially adapted child
restraint systems. It does

not work with child
restraint systems that are not compatible with
BabySmart™.
Never place anything between the seat
cushion and the child restraint system (e.g. a
cushion), as this reduces the effectiveness of
the BabySmart™ air bag deactivation system.
The underside of the child restraint system
must lie against the seat cushion of the front-
passenger seat. In the event of an accident,
an incorrectly installed child restraint system
could injure the child instead of offering
protection.
Observe the manufacturer's instructions
when installing special child restraint
systems. Occupant safety

WARNING
If the 00730074 indicator lamp illuminates and remains illuminated when the weight of a typical
adult or someone larger than a small individual has been detected on the passenger seat, do not
allow any occupant to use the passenger seat until the system has been repaired. Problem Possible causes/consequences and
0050 SolutionsThe 00730074
indicator lamp is
continuously lit. A special BabySmart™-compatible child restraint system is
mounted on the front-passenger seat.
The front-passenger air bag is therefore disabled.

an authorized Mercedes-Benz Center. The 00730074
indicator lamp does
not
light up and/or remain
lit

when a BabySmart™-
compatible child
restraint system is
installed on the front-
passenger seat. The BabySmart™ system is malfunctioning.

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.

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-
passenger seat. Otherwise, the
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
the belt tongue is

engaged in the buckle on
each of the lap-shoulder belts in the front.
R the front-passenger seat is occupied and
the belt tongue is engaged in the buckle on
the front-passenger side
The Emergency Tensioning Devices are
triggered depending on the type and severity
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
released generally does not constitute a

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
