81 Safety and Security
Occupant safety
The side impact air bags and window cur-
tain air bags are not deployed in impacts
which do not exceed the system’s deploy-
ment threshold.
Vehicles with OCS* only:
The front passenger side impact air bag
will not deploy if the OCS senses that the
front passenger seat is empty and the front
passenger seat belt is not fastened (latch
plate is not inserted into the buckle). With
an empty front passenger seat and the
seat belt fastened (latch plate properly in-
serted into buckle) the front passenger
side impact air bag will deploy indepen-
dently of the empty seat.Occupant Classification System*
The Occupant Classification System (OCS)
automatically turns the front passenger
front air bag on or off based on the classi-
fied occupant weight category determined
by weight sensor readings from the front
passenger seat.
Occupants must sit properly belted in a
position that is as upright as possible with
their back against the seat backrest and
feet on the floor to be correctly classified.
If the occupant’s weight is transferred to
another object in the vehicle (e.g. by lean-
ing on armrests), the OCS may not be able
to properly approximate the occupant’s
weight category.
Warning!G
Only use seat covers which have been test-
ed and approved by Mercedes-Benz for your
vehicle model. Using other seat covers may
interfere with or prevent the deployment of
the front side impact air bags or the rear
side impact air bags*. Contact your autho-
rized Mercedes-Benz Light Truck Center for
availability.
iThe system does not deactivate the front
passenger side impact air bag, the window
curtain air bag, and the emergency tensioning
device.

83 Safety and Security
Occupant safety
When the OCS senses that the front passen-
ger seat occupant is classified as being
heavier than the weight of a typical
12-month-old child seated in a standard
child restraint or as being a small individual
(such as a young teenager or a small adult),
the 59indicator lamp will illu-
minate for approximately 6 seconds when
the engine is started and then, depending on
occupant weight sensor readings from the
seat, remain illuminated or go out. With the
59indicator lamp illuminated,
the front passenger front air bag is deacti-
vated. With the 59indicator
lamp out, the front passenger front air bag is
activated.
When the OCS senses that the front passen-
g e r s e a t o c c u p a n t i s c l a s s i f i e d a s a n a d u l t o r
someone larger than a small individual, the
59indicator lamp will illumi-
nate for approximately 6 seconds when the
engine is started and then go out, indicating
that the front passenger front air bag is
activated.If the 59indicator lamp is illu-
minated, the front passenger front air bag is
deactivated and will not be deployed.
If the 59indicator lamp is not
illuminated, the front passenger front air
bag is activated and will be deployed:

in the event of certain frontal impacts

if impact exceeds a preset deployment
threshold

independently of the side impact air
bags.
If the front passenger front air bag is de-
ployed, the rate of inflation will be influ-
enced by:

the rate of vehicle deceleration as
assessed by the air bag control unit

the front passenger’s weight category
as identified by the Occupant Classifica-
tion System (OCS)
Warning!G
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front seat-
ing 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 or child restraint
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.

tion system. Please contact an authorized
Mercedes-Benz Light Truck Center for in-
formation on availability. With the special
child seat properly installed, the front pas-
senger front air bag will not deploy.The 59indicator lamp locat-
ed in the center console will be illuminat-

After turning the SmartKey in the starter
switch to position1 or2 or pressing the
KEYLESS-GO* start/stop button once or
twice, the 59indicator lamp
located in the center console comes on for
approximately 6 seconds and then goes
out.
If the 59indicator lamp
should not come on or is continuously lit,
the system is not functioning. You must
see an authorized Mercedes-Benz Light
Truck Center before seating any child on
the passenger seat.
More information can be found in the
“Practical hints” section (
page 450).
iThe system does not deactivate the side im-
pact air bag, the window curtain air bag and the
emergency tensioning device.
Warning!G
The BabySmartTM air bag deactivation sys-
tem will ONLY work with a special child seat
designed to operate with it. It will not work
with child seats which are not BabySmart
TM
compatible.
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the effectiveness of the deactivation sys-
tem. The bottom of the child seat must
make full contact with the passenger seat
cushion. An incorrectly mounted child seat
could cause injuries to the child in case of an
accident, instead of protecting the child.
Follow the manufacturer’s instructions for
installation of special child seats.

89 Safety and Security
Occupant safety
Warning!G
Always fasten your seat belt before driving
off. Always make sure your passengers are
properly restrained.
Failure to wear and properly fasten and po-
sition your seat belt greatly increases your
risk of injuries and their likely severity in an
accident. You and your passengers should
always wear seat belts.
If you are ever in an accident, your injuries
can be considerably more severe without
your seat belt properly buckled. Without
your seat belt buckled, you are much more
likely to hit the interior of the vehicle or be
ejected from it. You can be seriously injured
or killed.
In the same crash, the possibility of injury or
death is lessened if you are properly wearing
your seat belt. Air bags can only protect as
they are designed if the occupants are
properly wearing their seat belts.
Warning!G
Never ride in a moving vehicle with the seat
backrest in an excessively reclined position
as this can be dangerous. You could slide
under the seat belt in a collision. If you slide
under it, the belt would apply force at the ab-
domen or neck. That could cause serious or
even fatal injuries. The seat backrest and
seat belt provide the best restraint when the
wearer is in a position that is as upright as
possible and the belt is properly positioned
on the body.
Warning!G
Never let more people ride in the vehicle
than there are seat belts available. Make
sure everyone riding in the vehicle is cor-
rectly restrained with a separate seat belt.
Never use a seat belt for more than one per-
son at a time.
Warning!G
Damaged seat belts or belts that were highly
stressed in an accident must be replaced
and their anchoring points must also be
checked.
Only use seat belts which have been
approved by Mercedes-Benz.
Do not make any modifications to the seat
belts. This can lead to unintended activation
of the ETDs or to failure.
Do not bleach or dye seat belts as this may
severely weaken them. In a crash they may
not be able to provide adequate protection.
Have all work carried out only by qualified
technicians. Contact an authorized
Mercedes-Benz Light Truck Center.

95 Safety and Security
Occupant safety
Infants and small children should be
seated in an appropriate infant or child
restraint system properly secured in
accordance with the manufacturer’s
instructions for the child restraint, that
complies with U.S. Federal Motor Vehicle
Safety Standards 213 and 225 and
Canadian Motor Vehicle Safety Standards
213 and 210.2.
A statement by the child restraint manu-
facturer of compliance with these
standards can be found on the instruction
label on the restraint and in the instruction
manual provided with the restraint.
When using any infant or child restraint
system, make sure to carefully read and
follow all manufacturer’s instructions for
installation and use.
Please read and observe warning labels
affixed to the inside of the vehicle and to
infant or child restraints.
Warning!G
Vehicles with BabySmartTM air bag deactiva-
tion system, Canada only:
Children 12 years old and under must never
ride in the front seat, except in a
Mercedes-Benz authorized BabySmart
TM
compatible child seat, which operates with
the BabySmart
TM system installed in the
vehicle to deactivate the front passenger
front air bag when it is properly installed.
Otherwise they will be struck by the air bag
when it inflates in a crash. If this happens,
serious or fatal injury will result.
Warning!G
According to accident statistics, children
are safer when properly restrained in the
rear seating positions than in the front seat-
ing 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 or child restraint
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.

Child seat anchors – LATCH type
This vehicle is equipped with two LATCH
(L
ower Anchors and Tethers for CHildren)
type anchors (at each of the outer rear
seats) for the installation of a LATCH child
seat with matching mounting fittings.

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 se-
cure child restraint with the vehicle’s
seat belt according to the child seat
manufacturer’s instructions. For
children larger than the typical
12-month-old child, the front passenger
front air bag may or may not be
activated (
page 82).
Warning!G
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. Posi-
tion shoulder belt across chest and shoul-
der, not face or neck. A booster seat may be
necessary to achieve proper belt positioning
for children from 41 lb 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.
Do not leave children unattended in the
vehicle, even if the children are secured in a
child restraint system.
A child’s unsupervised access to a vehicle
could result in an accident and/or serious
personal injury.
