in the area of the door where the window
curtain air bag inflates. This could result in
serious injuries or death should the window
curtain air bag be deployed. 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.
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™ air bag deactivation 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.
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.GWarning!
Accident research shows that the safest place
for children in an automobile is in a rear seat.
Should you choose to place a child 12 years
old or under in the front passenger seat of
your vehicle, you must properly use a
BabySmart TM
child restraint which will turn off
the front passenger front air bag.
To help avoid the possibility of injury, please
follow these guidelines:
(1)Always sit as upright as possible,
wear the seat belt properly, and for
children 12 years old and under,
use an appropriately sized infant
restraint, toddler restraint, or
booster seat recommended for the
size and weight of the child.(2)Always wear seat belts properly.The air bags are only deployed if the air bag
control unit detects the need for deployment.
Only in the event of such a situation will they
provide their supplemental protection.
The driver and passenger should always wear
their seat belts. Otherwise, it is not possible
for the air bags to provide their supplemental
protection.
In the event of other types of impacts and
impacts below air bag deployment
thresholds, the air bags will not deploy. The
driver and passengers 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
protection in a rollover.
Air bags provide additional protection; they
are not, however, a substitute for seat belts.
All vehicle occupants must fasten their seat
belts regardless of whether your vehicle is
equipped with air bags or not.
It is important for your safety and that of your
passenger to have deployed air bags replaced
and to have any malfunctioning air bags
repaired. This will help to make sure the air
bags continue to perform their protective
function for the vehicle occupants in the
event of a crash.
Front air bagsGWarning
Observe "Important safety notes"
( Y page 36).
The front air bags increase protection for the
driver's and front-passenger's head, neck and
chest.
Occupant safety37SafetyZProCarManuals.com
passenger air bag if the system recognizes
that the front-passenger seat is empty .
If the front-passenger seat is occupied by an
adult or young person and the 4/
indicator lamp is lit up, the front-passenger air
bag is disabled. If the front-passenger seat is
recognized as empty, the air bag control unit
will not deploy the front-passenger air bag in
the event of a collision.
Ask your passenger to sit correctly on the
front-passenger seat in an upright position
until the 4/ indicator lamp goes out.
If the 4/ indicator lamp does not go
out, please consult an authorized Mercedes-
Benz Center.
Window curtain air bagsGWarning
Observe "Important safety notes"
( Y page 36).
The 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.
The 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 overturns 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 with deceleration rates which do not
exceed the system's preset deployment
thresholds for vehicle deceleration or
acceleration. You will then be protected by
the fastened seat belt.
BabySmart™ air bag deactivation
system
How the air bag deactivation system
functions
Your vehicle is equipped with a BabySmart™
system.
GWarning!
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 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 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.GWarning!
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.
GWarning
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.

Important safety notes
The NECK-PRO head restraints increase
protection to the driver's and front
passenger's head and neck. To this end, the
NECK-PRO head restraints on the driver's and
front-passenger seats are moved forwards
and upwards in the event of a rear-end
collision of a certain severity. This provides
better head support.
GWarning
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.
GWarning
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.
