When leaving the vehicle, alwaystake the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
GWARNING
If persons, particularly children are subjected to prolonged exposure to extreme heat or
cold, there is arisk of injury, possibly even
fatal. Never leave children unattended in the
vehicle.
GWARNING
If the child restraint system is subjected to
direct sunlight, parts may get very hot. Chil-
dren may burn themselves on these parts,
particularly on the metal parts of the child
restraint system. There is arisk of injury.
If you leave the vehicle, takin gthe child with
you, alwayse nsure that the child restraint
system is not exposed to direct sunlight. Pro- tect it with ablanket ,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.
Always ensure that all vehicle occupantsh ave
their seat belts fastened correctly and are sitting
properly. Particular attention must be paid to
children.
Observe the safety notes on the seat belt
(
Ypage 40) and the notes on correct use of seat
belts (Ypage 41).
Ab ooster seat may be necessary to achieve
proper seat belt positionin gfor children over
41 lbs (1 8kg)until they reach aheight where a
three-point seat belt can be properly fastened
without abooster seat.
Special seat belt retractor
GWARNING
If the seat belt is released while driving, the
child restraint system will no longer be
secured properly. The special seat belt retrac- tor 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 atten-
tion to road and traffic conditions. Reactivate
the special seat belt retractor and secure the
child restraint system properly.
All seat belts except the driver's seat belt are
equipped with aspecial 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 achild restraint system:
XAlways comply with the child restraint system
manufacturer's installation instructions.
XPull the seat belt smoothly out of the belt sash
guide.
XEngage the seat belt tongue in the belt buckle.
Activating the special seat belt retractor:
XPull the seat belt out fully and let the inertia
reel retract it again.
While the seat belt is retracting, you should
hear aratchetin gsound. The special seat belt
retractor is activated.
XPush the child seat restraint system down so
that the seat belt is tight and does not loosen.
Removing achild restraint system and deacti-
vating the special seat belt retractor:
XAlways comply with the child restraint system
manufacturer's installation instructions.

Safety
GWARNING
If the child restraint system is installed incor-
rectly on asuitable 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 instruc-
tions and the notes on use. Please ensure,
that the base of the child restraint system is
alway sresting completely on the seat cush-
ion. 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.
GWARNING
If the child restraint system is installed incor-
rectly or is not secured, it can come loosei n
the event of an accident, heavy braking or a
sudden change in direction. The child
restraint system coul dbethrown about, strik-
ing vehicleo ccupants. There is an increased
risk of injury ,possibly even fatal.
Always instal lchild restraint systems prop-
erly,e ven if they are not being used .Make
sure that you observe the child restraint sys-
tem manufacturer's installation instructions.
You wil lfind further information on stowing
objects, luggage or loads under "Loading guide-

GWARNING
Child restraint systems or their securing sys-
tems which have been damaged or subjected
to aloadinana ccident 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

Replace child restraint systems which have
been damaged or subjected to aloadina n
accident as soon as possible.H ave the secur-
ing systems on the child restraint system

before you install achild restraint system
again.
The securing systems of child restraint systems
are:
Rthe seat belts ystem
Rthe LATCH-type (ISOFIX) securing rings
Rthe Top Tether anchorages
iIf it is absolutel ynecessary to install achild

All child restraint systems must meet the fol-
lowing standards:
RU.S. FederalM otor Vehicle Safety Standards
213 and 225
RCanadian Motor Vehicle Safety Standards
213 and 210.2
Confirmation that the child restraint system cor-
responds to the standards can be found on an
instruction label on the child restraint system.
This confirmatio ncan als obefound in the instal-
lation instructions that are included with the
child restraint system.
Observe the warning labels in the vehiclei nte-
rior and on the child restraint system.
LATCH-type (ISOFIX) chil dseat secur-
ing system
GWARNING
LATCH-type (ISOFIX) child restraint systems
do not offer sufficient protective effect for
children whosew eight is greater than 48 lbs
(22 kg )who are secure dusing the safety belt
integrated in the child restraint system. In the
event of an accident, achild might not be
restrained correctly. This poses an increased
risk of injury or even fatal injury.
If the child weighs more than 48 lbs (22 kg),
only use LATCH-type (ISOFIX) child restraint
systems with which the child is als osecured
with the vehicles eat belt. Also secure the

Safety
GWARNING
If you secure achild in aforward-facing child
restraint system on the front-passenge rseat
and you position the front-passenge rseat too
close to the dashboard, in the event of an
accident, the child could:
Rcome into contact with the vehicle's inte-
rior if the PASSENGER AIR BAG OFF indi-
cator lamp is lit, for example
Rbe struck by the air bag if the PASSENGER
AIR BAG OFF indicator lamp is off
This poses an increased risk of injury or even fatal injury.
Move the front-passenge rseat as far back as
possible.A lways make sure that the shoulder
belts trap is correctly routed from the vehicle
belts ash guide to the shoulderb eltguide on
the child restraint system. The shoulderb elt
strap must be routed forwards and down-

General notes
Accident statistics show that children secured
in the rear seats are safer than children secured
in the front-passenge rseat. For this reason,
Mercedes-Benz strongly advises that you install
the child restraint system on arear seat.
If it is absolutel ynecessary to install achild
restraint system on the front-passenge rseat,
alway sobserve the information on the "Baby-
Smart™ air bag deactivation system"
(
Ypage5 3).
You can thus avoi dthe risks that coul darisea s
ar esult of:
Rac hild restraint system that is not detected
by the BabySmart™ air bag deactivation sys-
tem sensor system
Rthe unintentional deactivation of the front-
passenger front air bag
Rthe unsuitabl epositioning of the child
restraint system, e.g. too close to the dash-
board
Rearward-facin gchildr estraint system
If it is absolutel ynecessary to install arearward-
facing child restraint system on the front-
passenger seat, alway smake sure that the
front-passenge rfront air bag is deactivated.
Only if the PASSENGER AIR BAG OFF indicator
