77 Safety and Security
Occupant safety
A child in a rear-facing child restraint on
the passenger seat will be seriously in-
jured or even killed if the passenger
front air bag inflates in a collision which
could occur under some circumstances,
even with the air bag technology in-
stalled in your vehicle.
If you install a rear-facing child restraint
on the passenger seat, make sure that
the 5/indicator lamp is illumi-
nated, indicating that the passenger
front air bag is deactivated. Should the
5/ indicator lamp not illuminate
or go out while the restraint is installed,
please check installation. Periodically
check the 5/ indicator lamp
while driving to make sure the
5/ indicator lamp is illuminated.
If the 5/ indicator lamp goes out
or remains out, do not transport a child
on the passenger seat until the system
has been repaired. A child in a
rear-facing child restraint on the
passenger seat will be seriously injured
or even killed if the passenger front air
bag inflates.
If you place a child in a forward-facing
child restraint on the passenger seat,
move the seat as far back as possible,
use the proper child restraint recom-
mended 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.
For children larger than the typical
12-month-old child, the passenger front
air bag may or may not be activated
(
page 74).
iDeployment of the driver front air bag does
not mean that the passenger front air bag also
should have deployed.
The Occupant Classification System (
page 74)
may have determined:
that the seat was empty or occupied by the
weight up to or less than that of a typical
12-month-old child seated in a standard
child restraint – both instances where the
system suppresses deployment of the pas-
senger front air bag even though the impact
met the criteria and was of sufficient severity
to deploy the driver front air bag.
that the seat was occupied by a small individ-
ual (such as a young teenager or a small
adult) or a child weighing more than the
weight of a typical 12-month-old child in a
standard child restraint – instances where
the system may suppress deployment of the
passenger front air bag even though the
impact met the criteria and was of sufficient
severity to deploy the driver front air bag.

Seat belts
The use of seat belts and infant and child
restraint systems is required by law in all
50 states, the District of Columbia, the
U.S. territories and all Canadian provinces.
Even where this is not the case, all vehicle
occupants should have their seat belts
fastened whenever the vehicle is in
motion.
For information on fastening seat belts,
see “Fastening the seat belts” (
page 50).
Warning!G
If the 5/ indicator lamp should not
illuminate, the system is not functioning.
You must see an authorized Mercedes-Benz
Center before seating any child on the
passenger seat.
Warning!G
Never place anything between seat cushion
and child seat (e.g. pillow), since it reduces
the effectiveness of the Occupant Classifi-
cation System. 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 increasing protec-
tion for the child.
Follow the manufacturer’s instructions for
installation of child seats.
iFor information on infants and children
traveling with you in the vehicle and restraint
systems for infants and children, see “Children
in the vehicle” (
page 84).
Warning!G
Always fasten your seat belt before driving
off. Always make sure your passenger is
properly restrained.
Failure to wear and properly fasten and
position your seat belt greatly increases
your risk of injuries and their likely severity
in an accident. You and your passenger
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.
81 Safety and Security
Occupant safety
Warning!G
USE SEAT BELTS PROPERLY
Seat belts can only work when used
properly. Never wear seat belts in any
other way than as described in this
section, as that could result in serious
injuries in case of an accident.
Each occupant should wear their seat
belt at all times, because seat belts help
reduce the likelihood of and potential
severity of injuries in accidents, includ-
ing rollovers. The integrated restraint
system includes SRS (driver air bag,
driver-side knee bag, passenger front air
bag, head-thorax air bags) and ETD (seat
belt emergency tensioning device). The
system is designed to enhance the
protection offered to properly belted
occupants in certain frontal (front air
bags, driver-side knee bag and ETD) and
side (head-thorax air bags and ETD) im-
pacts which exceed preset deployment
thresholds.
Never wear the shoulder belt under your
arm, against your neck or off your shoul-
der. In a frontal crash, your body would
move too far forward. That would
increase the chance of head and neck
injuries. The shoulder belt would also
apply too much force to the ribs or abdo-
men, which could severely injure inter-
nal organs such as your liver or spleen.
Never wear seat belts over rigid or
breakable objects in or on your clothing,
such as eyeglasses, pens, keys, etc., as
these might cause injuries.
Position the lap belt as low as possible
on your hips and not across the abdo-
men. If the lap belt is positioned across
your abdomen, it could cause serious in-
juries in a crash.
Never use a seat belt for more than one
person at a time. Do not fasten a seat
belt around a person and another
person or other objects.
Seat belts should not be worn twisted.
In a crash, you would not have the full
width of the seat belt to manage impact
forces. The twisted seat belt against
your body could cause injuries.
Pregnant women should also always use
a lap-shoulder belt. The lap belt portion
should be positioned as low as possible
on the hips to avoid any possible
pressure on the abdomen.
Never place your feet on the instrument
panel, dashboard or on the seat. Always
keep both feet on the floor in front of the
seat.
When using a seat belt to secure infant
or toddler restraints or children in
booster seats, always follow the child
seat manufacturer’s instructions.

Infant and child restraint systems
We recommend all infants and children be
properly restrained at all times while the
vehicle is in motion.
The passenger lap-shoulder belt has a
special seat belt retractor for secure fas-
tening of child restraints.
To fasten a child restraint follow child re-
straint instructions for mounting. Then pull
the shoulder belt out completely and let it
retract. During seat belt retraction, a ratch-
eting sound can be heard to indicate that
the special seat belt retractor is activated.
The seat belt is now locked. Push down on
child restraint to take up any slack.
To deactivate, release seat belt buckle
and let seat belt retract completely. The
seat belt can again be used in the usual
manner.The use of infant or child restraints is re-
quired by law in all 50 states, the District of
Columbia, the U.S. territories, and all
Canadian provinces.
Infants and small children should be
seated in an appropriate infant or child
restraint system which is properly secured
by a lap-shoulder belt and 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 this standard
can be found on the instruction label on
the restraint and in the instruction manual
provided with the restraint.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.
If children open a door, they could
injure other persons
get out of the car and injure themselves
or be injured by following traffic
Do not carry heavy or hard objects in the
passenger compartment unless they are
firmly secured in place.

86 Safety and Security
Occupant safety
When using any infant restraint, toddler
restraint, or booster seat, be sure to care-
fully read and follow all manufacturer’s in-
structions for installation and use.
Please read and observe warning labels
affixed to inside of the vehicle and to infant
or child restraints.
Warning!G
Children 12 years old and under must be
seated and properly secured in an appropri-
ate 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 fully in
accordance with the child seat manufactur-
er’s instructions.
Occupants, especially children, should nev-
er place their bodies or lean their heads in
the area of the door where the head-thorax
air bag inflates. This could result in serious
injuries or death should the head-thorax air
bag be deployed. Always sit as upright as
possible, properly use the seat belts and 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 you place a
child in the passenger seat:
Your vehicle is equipped with air bag
technology designed to turn off the pas-
senger front air bag in your vehicle when
the OCS senses the weight of a typical
12-month-old child or less along with
the weight of a standard appropriate
child restraint on the passenger seat.
A child in a rear-facing child restraint on
the passenger seat will be seriously in-
jured or even killed if the passenger
front air bag inflates in a collision which
could occur under some circumstances,
even with the air bag technology in-
stalled in your vehicle.
If you install a rear-facing child restraint
on the passenger seat, make sure that
the 5/indicator lamp is illumi-
nated, indicating that the passenger
front air bag is deactivated. Should the
5/ indicator lamp not illuminate
or go out while the restraint is installed,
please check installation. Periodically
check the 5/ indicator lamp
while driving to make sure the
5/indicator lamp is illuminated.
If the 5/ indicator lamp goes out
or remains out, do not transport a child
on the passenger seat until the system
has been repaired. A child in a rear-fac-
ing child restraint on the passenger seat
will be seriously injured or even killed if
the passenger front air bag inflates.
87 Safety and Security
Occupant safety
If you place a child in a forward-facing
child restraint on the passenger seat,
move the seat as far back as possible,
use the proper child restraint recom-
mended 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.
For children larger than the typical
12-month-old child, the passenger front
air bag may or may not be activated
(
page 74).
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.
Warning!G
Children too big for a toddler restraint must
ride in seats using regular seat belts. Posi-
tion the shoulder belt across chest and
shoulder, not face or neck. A booster seat
may be necessary to achieve proper seat
belt positioning for children over 41 lbs 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.

Prior to operating the vehicle, the driver
should check and adjust the seat height,
seat position fore and aft, and seat back-
rest angle if necessary, to ensure adequate
control, reach and comfort. The head
restraint should also be adjusted for
proper height. See also the section on
air bags (
page 70) for proper seat
positioning.
In addition, adjust the steering wheel to
ensure adequate control, reach, operation
and comfort. Both the interior and exterior
rear view mirrors should be adjusted for
adequate rear vision.
Fasten seat belts. Infants and small
children should be seated in an appropri-
ate infant or child restraint system which is
properly secured by a lap-shoulder belt
and that complies with U.S. Federal Motor
