83 Safety and Security
Occupant safety
Children in the vehicle
If an infant or child is traveling with you in
the vehicle:
Secure the child using an infant or child
restraint appropriate to the age and
size of the child.
Make sure the infant or child is proper-
ly secured at all times while the vehicle
is in motion.
Infant and child restraint seats and
information on choosing an appropriate
restraint system can be obtained from any
Mercedes-Benz Center.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 spe-
cial seat belt retractor for the 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 the seat belt retraction a
ratcheting sound can be heard to indicate
that the special seat belt retractor is acti-
vated. The 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 man-
ner.Warning!
G
Do not leave children unattended in the
vehicle, even if they are secured in a child
restraint system. The children could
injure themselves on parts of the vehicle
be seriously or fatally injured through
excessive exposure to extreme heat or
cold
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.
For more information, please refer to the
“Useful features” section (
page 233)
through (
page 238).
Unsecured or improperly positioned cargo
increases a child’s risk of injury in the event
of
strong braking maneuvers

85 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-fac-
ing 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).
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
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 belt po-
sitioning 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 ve-
hicle, even if the children are secured in a
child restraint system. Unsupervised chil-
dren in a child restraint system may use ve-
hicle equipment and cause an accident
and/or serious personal injury.
