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

Problems with air bag deactivation systemProblemPossible causes/consequences and M SolutionsThe 45
indicator lamp is on
continuously.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.XHave the BabySmart™ system checked as soon as possible at
an authorized Mercedes-Benz Center.GWarning
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.
ProblemPossible causes/consequences and M SolutionsThe 45
indicator lamp does not
light up and/or stay on
when a BabySmart™-
compatible child
restraint system is
installed on the front-
passenger seat.The BabySmart™ system is malfunctioning.XMake sure there is nothing between the seat cushion and the
child restraint system.XCheck that the child restraint system is installed correctly.XIf 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
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.

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
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.GWarning
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.

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.GWarning!
Do not carry heavy or hard objects in the
passenger compartment or trunk unless they
are firmly secured in place.

Child restraint systems
Important safety notes
GWarning
Observe "Important safety notes"
( Y page 49).
We recommend all infants and children be
properly restrained using the child restraint
systems at all times while the vehicle is in
motion.
Always use a child restraint system that is
compatible with BabySmart™ on the front-
passenger seat.
The use of infant or child restraints is required
by law in all 50 states, the District of
Columbia, the U.S. territories and all
Canadian provinces.
Infants and children should always be seated
in an infant or child seat restraint system
appropriate for the size and weight of the
child. They must be properly secured in
accordance with the manufacturer's
installation instructions for the infant or child
seat restraint system. All infant and child seat
restraint systems must comply with the US
Federal Motor Vehicle Safety Standards 213
and 225 and Canadian Motor Vehicle Safety
Standards 213 and 210.2.
A statement by the child restraint
manufacturer of compliance with these
standards can be found on the instruction
label on the restraint system. You will also
find the statement in the instruction manual
provided with the child restraint system.
When using an infant restraint system, child
restraint system or booster seat, make sure
to carefully read and follow all manufacturer's
instructions for installation and use.
Please read the warning labels affixed to the
interior of the vehicle or to the infant restraint
or child restraint system.GWarning!

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 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
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. 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.
