2014 MERCEDES-BENZ SLK-Class ECU

Occupants, in particular children, must sit as
upright as possible, fasten the seat belt
correctly and use a suitable infant restraint
system, child restraint system or booster seat
suitable for the size and weight of the child.
Children can be seriously or even fatally
injured by an air bag deploying. Observe the
following information:
R Your vehicle is equipped with air bag
technology designed to deactivate the
front-passenger front air bag in your vehicle
when the system 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.
R A child in a rearward-facing child restraint
system on the front-passenger seat could
be seriously injured or even killed if the
front-passenger air bag inflates in a
collision despite the air bag technology
installed in your vehicle, which could occur
under some circumstances.
R If you install a rearward-facing child
restraint on the front-passenger seat, make
sure that the 0073PASSENGER AIR BAG
OFF indicator lamp is illuminated,
indicating that the front-passenger front air
bag is deactivated. Should the 0073
PASSENGER AIR BAG OFF indicator lamp
not illuminate or go out while a rearward-
facing child restraint system is installed,
please check installation. Periodically
check the 0073PASSENGER AIR BAG OFF
indicator lamp while driving to make sure it
is illuminated. If the 0073PASSENGER AIR
BAG OFF indicator lamp goes out or
remains out, do not transport a child on the
front-passenger seat.
R A child in a rearward-facing child restraint
system on the front-passenger seat can be
seriously injured or even killed if the front-
passenger air bag is deployed. R
When securing a child in a child restraint
system on the front-passenger seat, you
must:
- move the front-passenger seat as far
back as possible
- use a child restraint system that is
suitable for the age, size and weight of
the child
- observe the manufacturer's installation
instructions in order to install and secure
the child restraint system correctly.
R For children larger than the typical 12-
month-old child, the front-passenger front
air bag may or may not be activated. G
WARNING
If the child restraint system is installed
incorrectly on a suitable seat, it cannot
protect as intended. The child cannot then be
restrained in the event of an accident, heavy
braking or sudden changes of direction. There
is an increased risk of injury, possibly even
fatal.
Make sure that you observe the child restraint
system manufacturer's installation
instructions and the notes on use. Please
ensure, that the base of the child restraint
system is always resting completely on the
seat cushion. Never place objects, e.g.
cushions, under or behind the child restraint
system. Only use child restraint systems with
the original cover designed for them. Only
replace damaged covers with genuine covers. G
WARNING
If the child restraint system is installed
incorrectly or is not secured, it can come
loose in the event of an accident, heavy
braking or a sudden change in direction. The
child restraint system could be thrown about,
striking vehicle occupants. There is an
increased risk of injury, possibly even fatal.
Always install child restraint systems
properly, even if they are not being used.
Make sure that you observe the child restraint 56
Child restraint systemsSafety

system manufacturer's installation
instructions.
G
WARNING
Child restraint systems or their securing
systems which have been damaged or
subjected to a load in an accident can no
longer protect as intended. The child cannot
then be restrained in the event of an accident,
heavy braking or sudden changes of direction.
There is an increased risk of injury, possibly
even fatal.
Replace child restraint systems which have
been damaged or subjected to a load in an
accident as soon as possible. Have the
securing systems on the child restraint
system checked at a qualified specialist
workshop, before you install a child restraint
system again. G
WARNING
Infants and small children should never share
a seat belt with another occupant. In the event
of 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 that are too large for a child restraint
must travel in seats using normal seat belts.
Position the shoulder belt across the chest
and shoulder, not the face or neck. A booster
seat may be necessary to achieve proper seat
belt positioning for children over 41 lbs
(18 kg) until they reach a height where a lap/
shoulder belt fits properly without a booster
seat.
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. G
WARNING
If children are left unsupervised in the vehicle,
they could:
R open the doors, thus endangering other
people or road users.
R get out and disrupt traffic.
R operate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
R release the parking brake.
R shift the automatic transmission out of
parking position P.
R shift the manual transmission into neutral.
R starting the engine.
There is a risk of an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children or animals unattended in the
vehicle. Always keep the SmartKey out of
reach of children. G
WARNING
If persons, particularly children are subjected
to prolonged exposure to extreme heat or
cold, there is a risk of injury, possibly even
fatal. Never leave children unattended in the
vehicle. G
WARNING
If the child restraint system is subjected to
direct sunlight, parts may get very hot.
Children may burn themselves on these parts,
particularly on the metal parts of the child
restraint system. There is a risk of injury.
If you leave the vehicle, taking the child with
you, always ensure that the child restraint
system is not exposed to direct sunlight.
Protect it with a blanket, for example. If the
child restraint system has been exposed to
direct sunlight, let it cool down before
securing the child in it. Never leave children
unattended in the vehicle. Child restraint systems
57Safety Z

If an infant or child is traveling in the vehicle:
X Secure the child with a child or infant seat
restraint system appropriate to the age and
weight of the child.
X Make sure that the infant or child is
properly secured at all times while the
vehicle is in motion.
Mercedes-Benz recommends that you always
properly secure all infants and children with
a child or infant seat restraint system for the
trip.
The use of seat belts and infant and child
restraint systems is required by law in:
R all 50 states
R the U.S. territories
R the District of Columbia
R all Canadian provinces
Infants and children must always be seated in
an appropriate infant or child restraint system
recommended for the size and weight of the
child. The infant or child restraint system
must be properly secured with a three-point
seat belt in accordance with the
manufacturer's instructions.
All infant or child restraint systems must meet
the following standards:
R U.S. Federal Motor Vehicle Safety
Standards 213 and 225
R Canadian Motor Vehicle Safety Standards
213 and 210.2
Confirmation that the child restraint system
corresponds to the standards can be found
on an instruction label on the child restraint
system. This confirmation can also be found
in the installation instructions that are
included with the child restraint system.
Always read and follow the manufacturer's
instructions when using an infant or child
restraint system or booster seat.
Observe the warning labels in the vehicle
interior or on the infant or child restraint. Special seat belt retractor
G
WARNING

child restraint system will no longer be
secured properly. The special seat belt
retractor is disabled and the inertia real draws
in a portion of the seat belt. The seat belt
cannot be immediately refastened. There is
an increased risk of injury, possibly even fatal.
Stop the vehicle immediately, paying
attention to road and traffic conditions.
Reactivate the special seat belt retractor and
secure the child restraint system properly.
The seat belt on the front-passenger side is
equipped with a special seat belt retractor.
When activated, the special seat belt
retractor ensures that the seat belt will not
slacken once the child restraint system has
been secured.
Installing a child restraint system:
X Always comply with the manufacturer's
installation instructions.
X Pull the seat belt smoothly from the seat
belt retractor.
X Engage the seat belt tongue in the belt
buckle.
Activating the special seat belt retractor:
