tion. &
WARNING Risk of injur
y or death due to
incorrect positioning of the forward-facing
child restraint system
If you secure a child in a forward-facing child
r
estraint system on the front passenger seat
that is positioned too close to the cockpit, in
the event of an accident, the child could:
= come into contact with the vehicle interior
if the PASSENGER AIR BAG OFF indicator
lamp is lit, for example
= be struck by the airbag if the PASSENGER
AIR BAG OFF indicator lamp is oM. 
Always move the front passenger seat as
f

ar back as possible and fully retract the
seat cushion length adjustment. While
doing so, always make sure that the
shoulder belt strap is correctly routed
from the seat belt outlet of the vehicle to
the shoulder belt guide on the child
restraint system. The shoulder belt strap
must be routed forwards and downwards
from the seat belt outlet. If necessary,
adjust the seat belt outlet and the front
passenger seat accordingly. 
Always comply with the child restraint
sy

stem manufacturer's installation
instructions. When Ntting
a c
hild restraint system to the front
passenger seat, observe the vehicle-speciNc infor-
mation (  page 78).
If a person is sitting on the front passenger seat:
PASSENGER AIR BAG OFF may be lit continuously
or be oM, depending on the person's stature. A person on the front passenger seat must always
obser
ve the following information:
= If the front passenger seat is occupied by an
adult or a person with a stature corresponding
to that of an adult, the PASSENGER AIR BAG
OFF indicator lamp must be oM. This indicates
that the front passenger airbag is enabled.
If the PASSENGER AIR BAG OFF indicator
lamp is lit continuously, an adult or person
with a build corresponding to that of an adult
must not use the front passenger seat.
Instead, they should use a rear seat.
= If the front passenger seat is occupied by a
person of smaller stature (e.g. a teenager or
small adult), the PASSENGER AIR BAG OFF
indicator lamp is either lit continuously or
remains oM, depending on the classiNcation.
- If the PASSENGER AIR BAG OFF indicator
lamp is oM: move the front passenger seat
as far back as possible, or the person of
smaller stature should use a rear seat.
- If the PASSENGER AIR BAG OFF indicator
lamp is lit continuously: the person of 58

WARNING Risk of injur
y or death when
the PASSENGER AIR BAG OFF indicator
lamp is lit
If the PASSENGER AIR BAG OFF indicator
lam
p remains lit aser the self-test, the front
passenger airbag is disabled.
If the front passenger seat is occupied, always
ensure that:
= The classiNcation of the person in the front
passenger seat is correct and the front
passenger airbag is enabled or disabled in
accordance with the person in the front
passenger seat.
= The person is seated properly with a cor-
rectly fastened seat belt.

aser an accident
Depending on t
he type and severity of the acci-
dent, and depending on the vehicle's equipment,
the following measures can be implemented, for
example:
= automatic braking (post-collision brake)
= activating the hazard warning lights
= triggering an automatic emergency call
(  page 385)
= switching oM the drive system and high-volt-
age on-board electrical system
= unlocking the vehicle doors
= lowering the side windows

Function of the post-collision brake
Depending on the accident situation, the post-col-
lision brake can minimise the severity of a further
collision or even avoid it.
If an accident is detected, the post-collision brake
can implement automatic braking. When the vehi-
cle has come to a standstill, the electric parking
brake is automatically applied.
The driver can cancel automatic braking by taking
the following actions:
= braking more strongly than automatic braking
= fully depressing the accelerator pedal with
force Safely transporting children in the vehicle
Always observe when children are travelling in the
v
ehicle %
Also strictly observe the safety notes for the
speciNc situation. In t

his way you can recog-
nise potential risks and avoid dangers if chil- dren are travelling in the vehicle
(
 pag

e 62).
Be diligent
Bear in mind t
hat negligence when securing a
child in the child restraint system may have seri-
ous consequences. Always be diligent in securing
a child carefully before every journey.
Never allow babies and children to travel sitting
on the lap of another vehicle occupant.
To improve protection for children younger than
12 years old or under 1.50 m in height,
Mercedes-Benz recommends you observe the fol-
lowing information:
= Always secure the child in a child restraint sys-
tem suitable for this Mercedes-Benz vehicle.
= The child restraint system must be appropriate
to the age, weight and size of the child.
= The vehicle seat must be suitable for Ntting a
child restraint system (  page 66).
Accident statistics show that children secured on
the rear seats are generally safer than children
secured on the front seats. For this reason, Mercedes-Benz strongly advises that you
Nt a
c
hild restraint system to a rear seat.
The generic term child restraint system
The generic term child restraint system is used in
this Owner's Manual. A child restraint system is,
for example:
= a baby car seat
= a rearward-facing child seat
= a forward-facing child seat
= a child booster seat with a backrest and seat
belt guide
Mercedes-Benz recommends using a child
booster seat with a backrest.
The child restraint system must be appropriate to
the age, weight and size of the child.
Observe laws and legal requirements
Always observe the legal requirements when
using a child restraint system in the vehicle.
Make sure that the child restraint system is
approved in accordance with the valid test speciN-
cations and guidelines. Further information can
be obtained at a qualiNed specialist workshop. Occupant safety

Only use approved child restraint systems
Only child restraint systems that meet the follow-
ing UNECE standards are permitted for use in the
vehicle:
= UN-R44
= UN-R129 (i-Size child restraint systems)
Information on child restraint system approval
categories and details on the approval label on
the child restraint system ( page 67). Detecting risks, avoiding danger
Securing systems for child restraint systems in
t
he vehicle
Only use the following securing systems for child
restraint systems:
= the ISOFIX or i-Size securing rings
= the vehicle's seat belt system
= the Top Tether anchorages Fitting an ISOFIX or an i-Size child restraint sys-
t

em is preferred.
Simply attaching to the securing rings on the vehi-
cle can reduce the risk of Ntting the child restraint
system incorrectly.
When securing a child with the integrated seat
belt of the ISOFIX or i-Size child restraint system,
always comply with the permissible gross weight
for the child and child restraint system
( page 70).
Advantage of a rearward-facing child restraint sys-
tem
It is preferable to transport a baby or a small child
in a suitable rearward-facing child restraint sys-
tem. In this case, the child sits in the opposite
direction to the direction of travel and faces back-
wards.
Babies and small children have comparatively
weak neck muscles in relation to the size and
weight of their head. The risk of injury to the cer-
vical spine during an accident can be reduced in a
rearward-facing child restraint system. Always secure a child restraint system correctly &
WARNING Risk of injur
y or death due to
incorrect installation of the child restraint
system
The child can then not be protected or
r
estrained as intended. 
Be sure to comply with the manufactur-
er's ins
tallation instructions for the child
restraint system and its correct use. 
Make sure that the entire base of the
c
hild restraint system always rests on
the sitting surface of the seat. 
Never place objects (e.g. cushions)
under or behind t

he child restraint sys-
tem. 
Use child restraint systems only with the
or

iginal cover designed for them. 
Always replace damaged covers with
g

enuine covers. 62
