mation given here.

the seat belt and/or latch plate cannot get
caught or pinched in the door or in the seat
mechanism. This can damage the seat belt and
impair the effectiveness of the seat belt, and/or
cause damage to the door and/or door trim pan-
el. Such damage is not covered by the
Mercedes-Benz Limit Warranty.
Damaged seat belts must be replaced. Contact
an authorized Mercedes-Benz Center.
Warning!G
To prevent possible personal injury, always
keep hands and fingers away from the door
openings when closing the doors. Be espe-
cially careful when small children are
around.
Before closing doors, make sure there is no
possibility of someone getting caught in a
door during closing.
Warning!G
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. A child’s unsupervised ac-
cess to a vehicle could result in an accident
and/or serious personal injury.
iIf you hear a warning signal you have
forgotten to switch off the headlamps before
opening the driver’s door.

82 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 that the infant or child is
properly secured at all times while the
vehicle is in motion.Infant and child restraint systems
We recommend all infants and children be
properly restrained at all times while the
vehicle is in motion.
All lap-shoulder belts except the driver’s
seat belt have special seat belt retractors
for secure fastening of child restraints.
To fasten a child restraint, follow child
restraint instructions for mounting. Then
pull the shoulder belt out completely and
let it retract. During 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
manner.
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
If children open a door, they could
injure other persons
get out of the car and injure themselves
or be injured by oncoming 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.
Do not carry heavy or hard objects in the
passenger compartment or trunk unless
they are firmly secured in place. For more in-
formation, see “Loading” (
page 271), and
see “Useful features” (
page 276) in the
“Controls in detail” chapter.
Unsecured or improperly positioned cargo
increases a child’s risk of injury in the event
of
strong braking maneuvers
sudden changes of direction
an accident
