passenger air bag if the impact fulfills the
specified criteria. If the 45 indicator
lamp lights up, the front-passenger front air
bag is disabled and will not be deployed in
certain situations. If the 45 indicator
lamp does not light up, the front-passenger
front
air bag is enabled and can be deployed.
Window curtain air bags G
WARNING
Observe "Important safety notes"
(Y page 41). Window curtain air bags
:
enhance the level
of protection for the head, but not chest or
arms, of the vehicle occupants on the side of
the vehicle on which the impact occurs.
Window curtain air bags : 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 : 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 4 / indicator lamp is
illuminated, indicating that the front
passenger front air bag is deactivated.
Should the 4 / indicator lamp not
illuminate or go out while the restraint is
installed, please check installation.
Periodically check the 4 / indicator
lamp while driving to make sure the
4 / indicator lamp is illuminated. If
the 4 / 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 4 / indicator lamp remains
illuminated.
Please be sure to check the 4 /
indicator lamp every time you use a
BabySmart™ compatible child seat on the
front passenger seat. Should the 4 /
indicator lamp go out while the restraint is
installed, please check installation. If the
4 / 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

Problems with the air bag deactivation system
G
WARNING
If the 45 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
M SolutionsThe 45
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.
There is no BabySmart™-compatible child restraint system
mounted

on the front-passenger seat. The BabySmart™ system is
malfunctioning.
X Have the BabySmart™ system checked as soon as possible at
an authorized Mercedes-Benz Center. The 45
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.
X
Make sure there is nothing between the seat cushion and the
child restraint system.
X Check that the child restraint system is installed correctly.
X If the 45 indicator lamp does not light up, have the
BabySmart™ system checked as soon as possible at an
authorized Mercedes-Benz Center.
Do not transport a child on the front-passenger seat until the
air bag deactivation system has been repaired. NECK-PRO head restraints
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.
The NECK-PRO head restraints increase
protection to the driver's and the front
passenger's head and neck. The NECK-PRO

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
