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 toddler restraint, or
booster seat recommended for the size and
weight of the child. For additional
information, see “Children in the vehicle”
(
page 83).
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.
iThe memory function (page 127) lets you
store the settings for the seat position together
with the settings for the steering wheel and the
exterior rear view mirrors.
!When moving the seats, make sure there are
no items in the footwell or behind the seats; oth-
erwise you could damage the seats.

Front air bags
1Driver air bag
2Passenger air bag
Driver and front passenger front air bags
are deployed:
in the event of certain frontal impacts
if impact exceeds a preset deployment
threshold
independently of the front side impact
air bag (CLK coupe), head-thorax air
bag (CLK cabriolet) and/or the rear
side impact air bag*The air bags will not deploy in impacts
which do not exceed the system’s deploy-
ment thresholds. You will then be protect-
ed by the fastened seat belts.
The front passenger front air bag will only
be deployed if:the system, based on OCS weight sen-
sor readings, senses that the front pas-
senger seat is occupied
the 56 indicator lamp in the
center console is not lit (
page 76)

impact air bags*, window curtain air
bags
1Front side impact air bag
2Rear side impact air bag*
3Window curtain air bag
iThe front air bags in this vehicle have been
designed to inflate in two stages. This allows the
air bag to have different rates of inflation that are
based on the rate of relevant vehicle decelera-
tion as assessed by the air bag control unit.
On the front passenger side, the front air bag de-
ployment is additionally influenced by the pas-
senger’s weight category as identified by the
Occupant Classification System (OCS)
(
page 72).
The lighter the front passenger side occupant,
the higher the vehicle deceleration rate required
for the second stage inflation of the air bag.
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 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 275), and
see “Useful features” (
page 285) 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

til it engages.
Check the rear seat backrest to be
locked in its upright position
(
page 282).
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. Unsupervised
children in a child restraint system may use
vehicle equipment and may cause an
accident and/or serious personal injury.
iYour CLK cabriolet does not have and is not
required to have anchorage rings for a child
seat’s top tether strap in the rear seating posi-
tions. Child seats can be used with the seat belt,
or lower anchor system and seat belt, fully in ac-
cordance with the child seat manufacturer’s in-
structions.
iFor safety, make sure the hook2 has at-
tached to the anchorage ring1 beyond the
safety catch, as illustrated.
