Roll bars (CLK cabriolet)
The roll bars are integrated into the rear
head restraints.
The roll bars raise automatically in an acci-
dent or in a critical driving situation.You can manually lower the roll bars again
when the soft top is open (
page 431).
With the soft top closed, contact an autho-
rized Mercedes-Benz Center to have the
roll bars lowered. Do not attempt to lower
the roll bars manually with the soft top
closed. Lowering the roll bars manually
with the soft top closed may impair the
function of the roll bars.
Warning!G
Make sure nothing is blocking the roll bars’
path of motion. Otherwise someone could
be injured when the roll bars are raised. The
head restraints should therefore always be
in the raised position when the rear seat is
occupied (
page 123).
iWhen the roll bars are raised automatically,
you will hear a ratcheting sound and the rear
head restraints will also rise.
iYou cannot lower the rear head restraints
with the rear head restraint lowering switch
(
page 123) when the roll bars are in the raised
position.
Also, you cannot operate the soft top using the
soft top switch when the roll bars are in the
raised position.

If the soft top is open, you can manually low-
er the roll bars (
page 431).

If the soft top is closed, contact an autho-
rized Mercedes-Benz Center to have the roll
bars lowered.
Warning!G
If the yellow roll bar warning lamp in
the clock does not go out after starting the
engine, or if it comes on while driving, then
the roll bar system is not operating properly
and may not activate in an accident. In this
case, raise the roll bars manually before
continuing to drive (
page 430).
For safety reasons, drive only with the roll
bars raised until the malfunction is repaired.
Have your vehicle checked at an authorized
Mercedes-Benz Center.

84 Safety and Security
Occupant safety
The use of infant or child restraints is
required by law in all 50 states, the District
of Columbia, the U.S. territories, and all
Canadian provinces.
Infants and small children should be seat-
ed in an appropriate infant or child
restraint system properly secured in accor-
dance with the manufacturer's instruc-
tions for the child restraint, that complies
with U.S. Federal Motor Vehicle Safety
Standards 213 and 225 and Canadian Mo-
tor Vehicle Safety Standards 213 and
210.2.
A statement by the child restraint manu-
facturer of compliance with these stan-
dards can be found on the instruction label
on the restraint and in the instruction
manual provided with the restraint.When using any infant, or toddler restraint,
or booster seat, be 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.

anchors (

chor fittings for tether anchorages (
page 86).
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 recom-
mended for the size and weight of the child.
The infant or child restraint must be properly
secured with the vehicle’s seat belt, or:
CLK coupe: the seat belt and top tether
strap, or lower anchors and top tether
strap,
CLK cabriolet: the seat belt and lower
anchors,
fully in accordance with the child seat
manufacturer’s instructions.
Occupants, especially children, should nev-
er place their bodies or lean their heads in
the area of the door or the rear side trim
panel where the front side impact air bag
(CLK cabriolet: head-thorax air bag) and/or
the rear side impact air bag* inflates. This
could result in serious injuries or death
should the air bag be triggered. Always sit as
upright as possible, properly use the seat
belts and use 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 circumstances
require you to place a child in the front
passenger seat:

85 Safety and Security
Occupant safety

Your vehicle is equipped with air bag
technology designed to turn off the front
passenger 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 front
passenger seat.

A child in a rear-facing child restraint on
the front passenger seat will be
seriously injured or even killed if the
front passenger front air bag inflates in
a collision which could occur under
some circumstances, even with the air
bag technology installed in your vehicle.
The only means to completely eliminate
this risk is to never place a child in a
rear-facing child restraint in the front
seat. We therefore strongly recommend
that you always place a child in a
rear-facing child restraint in the back
seat.

If you must install a rear-facing child
restraint on the front passenger seat
because circumstances require you to
do so, make sure the 56 indica-
tor lamp is illuminated, indicating that
the front passenger front air bag is deac-
tivated. Should the 56 indicator
lamp not illuminate or go out while the
restraint is installed, please check in-
stallation. Periodically check the
56 indicator lamp while driving
to make sure the 56indicator
lamp is illuminated. If the 56
indicator lamp goes out or remains out,
do not transport a child on the front pas-
senger seat until the system has been
repaired. A child in a rear-facing child re-
straint on the front passenger seat will
be seriously injured or even killed if the
front passenger front air bag inflates.

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
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 front passenger
front air bag may or may not be activated
(
page 73).
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 over 41 lbs until they reach a
height where a lap/shoulder belt fits
properly without a booster.

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.

The CLK coupe and cabriolet are equipped
with two LATCH- (L
ower Anchors and Teth-
ers for CH
ildren) type anchors (at each of
the rear seats) for the installation of a
LATCH-type child seat with matching
mounting fittings.LATCH-type anchors
The LATCH-type anchors are located be-
tween the seat cushion and the backrest.
