vehicle. The child restraint system must beappropriate to the age, weight and size of
the child
R always observe the instructions and safety
notes in the "Children in the vehicle" sec-
tion of this Operator's Manual( Y page 55) in addition to the child
restraint system manufacturer's installa-
tion instructions
GWARNING
The seat belts may not perform their intended protective function if:
R they are damaged, modified, extremely
dirty, bleach or dyed
R the seat belt buckle is damaged or
extremely dirty
R the Emergency Tensioning Devices, belt
anchorages or inertia reels have been modi-
fied
Seat belts may sustain non-visible damage in an accident, e.g. due to glass splinters. Modi-
fied or damaged seat belts may tear or fail,
e.g. in an accident. Modified Emergency Ten-
sioning Devices could accidentally trigger or
fail to deploy when necessary. This poses an
increased risk of injury or even fatal injury.
Never modify the seat belts, Emergency Ten-
sioning Devices, belt anchorages or inertia
reels. Make sure that the seat belts are
undamaged, not worn out and clean. Follow-
ing an accident, have the seat belts checked
immediately at a qualified specialist work-shop.
Only use seat belts that have been approved
for your vehicle by Mercedes-Benz.
Proper use of the seat belts
Observe the safety notes on the seat belt ( Y page 44).
All vehicle occupants must be wearing the
seat belt correctly before beginning the jour-
ney. Also make sure that all vehicle occu-
pants are always wearing the seat belt cor-
rectly while the vehicle is in motion. When fastening the seat belt, always make
sure that:
R the seat belt tongue is only inserted to the
belt buckle belonging to that seat.
R the seat belt is tight across your body.
Avoid wearing bulky clothing, e.g. a winter coat.
R the seat belt is not twisted.
Only then can the forces which occur be
distributed over the area of the belt.
R the shoulder section of the belt is always
routed across the center of your shoulder.
The shoulder section of the belt must not
come into contact with your neck or be
routed under your arm. Where possible,
adjust the seat belt to the appropriate
height.
R the lap belt passes tightly and as low down
as possible across your lap.
The lap belt must always be routed across
your hip joints and not across your abdo-
men. This applies particularly to pregnant
women. If necessary, push the lap belt
down to your hip joint and pull it tight usingthe shoulder section of the belt.
R the seat belt is not routed across sharp,
pointed or fragile objects.
If you have such items located on or in your
clothing, e.g. pens, keys or eyeglasses,
store these in a suitable place.
R only one person is using a seat belt at atime.
Infants and children must never travel sit-
ting on the lap of a vehicle occupant. In the
event of an accident, they could be crushed
between the vehicle occupant and seat
belt.
R objects are never secured with a seat belt if
the seat belt is also being used by one of the
vehicle's occupants.
Seat belts are only intended to secure and
restrain vehicle occupants. Always observe
the "Loading guidelines" for securing objects,
luggage or loads ( Ypage 192).

Children in the vehicle
Important safety notes
Accident statistics show that children
secured in the rear seats are safer than chil-
dren secured in the front seats. For this rea-
son, Mercedes-Benz strongly advises that you
install a child restraint system on a rear seat.
Children are generally better protected there.
If a child younger than twelve years and under
5 ft (1.50 m)in height is traveling in the vehi-
cle:
R always secure this child in a restraint sys-
tem approved for Mercedes-Benz vehicles.
The child restraint system must be appro-
priate to the age, weight and size of thechild.
R be sure to observe the instructions and
safety notes in this section in addition to
the child restraint system manufacturer's
installation instructions.
GWARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example:
R release the parking brake.
R shift the automatic transmission out of the
parking position P.
R start the engine.
In addition, they may operate vehicle equip-
ment and become trapped. There is a risk of
an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
GWARNING
If persons, particularly children are subjected to prolonged exposure to extreme heat or
cold, there is a risk of injury, possibly even
fatal. Never leave children unattended in the
vehicle.
GWARNING
If the child restraint system is subjected to
direct sunlight, parts may get very hot. Chil-
dren may burn themselves on these parts,
particularly on the metal parts of the child
restraint system. There is a risk of injury.
If you leave the vehicle, taking the child with
you, always ensure that the child restraint
system is not exposed to direct sunlight. Pro-tect it with a blanket, for example. If the child
restraint system has been exposed to direct
sunlight, let it cool down before securing the
child in it. Never leave children unattended inthe vehicle.
Always make sure that all vehicle occupants
are positioned properly in their seats and
have correctly fastened their seat belts. Take
particular care with children.
Please take note of the safety notes on seat
belts ( Ypage 44) and the notes on their cor-
rect use ( Ypage 45).
A booster seat may be necessary to achieve
proper seat belt positioning for children over

BabySmart™ air bag deactivation sys-
tem
The BabySmart™ air bag deactivation sys-
tem's sensor system in the front-passenger
seat detects whether a special Mercedes-
Benz child restraint system with a trans-
ponder for the BabySmart™ air bag deactiva-
tion system has been installed. In this case,
the PASSENGER AIR BAG OFF indicator lamp lights up and remains lit. The front-passengerfront air bag is deactivated.
When the SmartKey is removed from the igni-
tion lock or is in position 0, the PASSENGER
AIR BAG OFF indicator lamp is not lit.
iIf the front-passenger front air bag is
deactivated by the BabySmart™ air bag
deactivation system, the following remain
enabled on the front-passenger side:
R the side impact air bag
R the pelvis air bag
R the window curtain air bag
R the Emergency Tensioning Device
GWARNING
If you secure a child in a child restraint system
on the front-passenger seat and the
PASSENGER AIR BAG OFF indicator lamp is
off, the front-passenger front air bag can
deploy in the event of an accident. The child
could be struck by the air bag. This poses an
increased risk of injury or even fatal injury.
Make sure that the front-passenger front air
bag has been disabled. The PASSENGER AIR
BAG OFF indicator lamp must be lit.
GWARNING
If the PASSENGER AIR BAG OFF indicator
lamp is lit, the front-passenger front air bag isdeactivated. It will not be deployed in the
event of an accident and cannot perform its
intended protective function. A person in the
front-passenger seat could then, for example, come into contact with the vehicle's interior,
especially if the person is sitting too close to
the dashboard. This poses an increased risk of injury or even fatal injury.
In this case the front-passenger seat may notbe used. You may only transport a child on the
front-passenger seat if they are seated in a
suitable rearward or forward-facing child
restraint system. Always observe the child
restraint system manufacturer's installation
instructions.
GWARNING
If you secure a child in a forward-facing child
restraint system on the front-passenger seat
and you position the front-passenger seat too close to the dashboard, in the event of an
accident, the child could:
R come into contact with the vehicle's inte-
rior if the PASSENGER AIR BAG OFF indi-
cator lamp is lit, for example
R be struck by the air bag if the PASSENGER
AIR BAG OFF indicator lamp is off
This poses an increased risk of injury or even fatal injury.
Move the front-passenger seat as far back as
possible. Always make sure that the shoulder belt strap is correctly routed from the vehicle
belt sash guide to the shoulder belt guide on
the child restraint system. The shoulder belt
strap must be routed forwards and down-
wards from the belt sash guide. If necessary,
adjust the belt sash guide and the front-

passenger seat accordingly. Always observe
the information about suitable positioning of
the child restraint system in this Operator's
Manual as well as the child restraint system
manufacturer's installation instructions.
PASSENGER AIR BAG OFF indicator lamp:
shows you whether the front-passenger front air bag is deactivated.
X Turn the SmartKey to position 1or 2in the
ignition lock.
The system carries out self-diagnostics.
The PASSENGER AIR BAG OFF indicator lamp
must light up for approximately six seconds.
If, after the system self-test, the
PASSENGER AIR BAG OFF indicator lamp: R is lit : the front-passenger front air bag is
deactivated. It will then not be deployed in
the event of an accident.
R is not lit , the sensor system did not detect
a child restraint system with transponder
for the BabySmart™ air bag deactivation
system. If, in the event of an accident, all
deployment criteria are met, the front-
passenger front air bag is deployed.
GWARNING
Electronic devices on the front-passenger
seat can affect the function of the Baby-
Smart™ air bag deactivation system, forexample:
R Laptop
R Mobile phone
R Transponder cards such as ski passes or
access passes
The front-passenger air bag could deploy acci-
dentally or not function as intended during an accident. This poses an increased risk of
injury or even fatal injury.
Do not place any of the devices mentioned
above or similar devices on the front-
passenger seat. Be aware of the status of thefront-passenger front air bag both before andduring the journey.
Child restraint system on the front-
passenger seat
General notes
Accident statistics show that children
secured in the rear seats are safer than chil-
dren secured in the front-passenger seat. For this reason, Mercedes-Benz strongly advises
that you install the child restraint system on a
rear seat.
If it is absolutely necessary to install a child
restraint system on the front-passenger seat,
always observe the information on the "Baby- Smart™ air bag deactivation system"( Y page 59).
You can thus avoid the risks that could arise
as a result of:
R a child restraint system that is not detected
by the BabySmart™ air bag deactivation
system sensor system
R the unintentional deactivation of the front-
passenger front air bag
R the unsuitable positioning of the child
restraint system, e.g. too close to the dash-
board
