Forward-facing child restraint system
If you secure a child in a forward-facing child
restraint system on the co-driver's seat, you
must always move the co-driver's seat as far
back as possible. The base of the child restraint system must lie fully on the co-driver's seat
cushion. The backrest of the child restraint sys-
tem must lie as flat against the co-driver's seat
backrest as possible. The child restraint system may not touch the roof or be put under strain by
the head restraint. Adjust the angle of the seat
backrest and the head restraint position accord- ingly. Always make sure that the shoulder belt
strap is correctly routed from the seat-belt
extender on the co-driver's seat to the shoulder
belt guide on the child restraint system. The
shoulder belt strap must be routed forwards
from the retracted seat-belt extender for the co- driver's seat.
Always observe the information about suitable
positioning of the child restraint system
(Y page 55) as well as the child restraint sys-
tem manufacturer's installation and operating
instructions. 54

Problems with automatic child seat recognition
Problem
Possible causes/consequences and
M
MSolutions The PASSENGER AIR
BAG OFF indicator lamp
on the centre console is
lit. A special Mercedes-Benz child restraint system with a transponder for
automatic child seat recognition has been fitted to the front-
passenger seat. The front-passenger front airbag has therefore been
disabled as desired. G
WARNING
There is no child restraint system fitted to the front-passenger seat.
Automatic child seat recognition is malfunctioning, for example due to
electronic devices on the front-passenger seat.
There is a risk of injury.
X Remove electronic equipment from the front-passenger seat, e.g.:
R laptop
R mobile phone
R a card with a transponder, such as a ski pass or access pass
If the PASSENGER AIR BAG OFF indicator lamp remains lit, the front- passenger seat may not be used.
X Consult a qualified specialist workshop. When you switch the
ignition on, the
6
restraint system warning lamp lights up and/or
the PASSENGER AIR
BAG OFF indicator lamp
does not light up briefly. G
WARNING
Automatic child seat recognition is malfunctioning.
Do not install a child restraint system on the front-passenger seat.
It is recommended that you fit the child restraint system to a suitable rear seat.
X Consult a qualified specialist workshop.
X Please also refer to the notes about the restraint system warning
lamp (Y page 228). Suitable positioning of the child
restraint system
Introduction Only child restraint systems which are approved
in accordance with the ECE standard ECE R44
are permitted for use in the vehicle.
For certain child restraint systems in weight cat-
egories II or III, this can mean that the area of
use is restricted. The maximum size setting of
the child restraint system is not possible due to possible contact with the roof.
"Universal" category child restraint systems can
be recognised by their orange approval label and the text "Universal". Example: approval label on the child restraint
system
"Universal" category child restraint systems can
be used on the seats indicated with U, UF or IUF according to the tables "Suitability of the seats
for attaching belt-secured child restraint sys- Children in the vehicle
55Safety Z
Page 59 of 345

tems" or "Suitability of the seats for attaching an
ISOFIX child restraint system".
Semi-universal child restraint systems are indi-
cated by the text "semi-universal" on the
approval label. These can be used if the vehicle and the seat are listed in the child restraint sys-
tem manufacturer's vehicle model list. For more
information, contact the child restraint system
manufacturer or visit their website.
If it is absolutely necessary to fit a child restraint system to the front-passenger seat:
X Always pay attention to the instructions under
"Child restraint system on the front-
passenger seat" (Y page 52).
There you will find instructions on how to cor- rectly route the shoulder belt strap from the
vehicle seat-belt extender or belt outlet to the
shoulder belt guide on the child restraint sys-
tem (Y page 54).
X Move the front-passenger seat as far back as
possible and into the lowest position.
X Move the backrest to an almost vertical posi-
tion.
The entire base of the child restraint system
must always rest on the seat cushion of the
front-passenger seat. The backrest of the
forward-facing child restraint system must, as far as possible, be resting on the backrest of
the front-passenger seat. The child restraint
system must not touch the roof or be put
under strain by the head restraint. Adjust the
angle of the seat backrest and the head
restraint position accordingly. Also observe
the child restraint system manufacturer's
installation instructions. 56

Suitability of the seats for attaching belt-secured child restraint systems
If you use a baby car seat of category 0 or 0+ or a rearward-facing child restraint system of category
I on a rear seat, you must adjust the driver's or front-passenger seat so that the seat does not touch
the child restraint system.
Always observe the notes in the "Child restraint system" section (Y page 48) and the child restraint
system manufacturer's installation instructions.

Driving safety systems overview
In this section, you will find information about
the following driving safety systems:

R PRE-SAFE ®
Brake (Y page 69)
R STEER CONTROL (Y page 71) Important safety notes
If you fail to adapt your driving style or if you are
inattentive, the driving safety systems can nei-
ther reduce the risk of an accident nor override the laws of physics. Driving safety systems are
merely aids designed to assist driving. You are
responsible for maintaining the distance to the
vehicle in front, for vehicle speed, for braking in
good time, and for staying in lane. Always adapt
your driving style to suit the prevailing road and weather conditions and maintain a safe distance
from the vehicle in front. Drive carefully.
The driving safety systems described only work as effectively as possible when there is ade-
quate contact between the tyres and the road
surface. Please pay special attention to the
notes on tyres, recommended minimum tyre
tread depths etc. (Y page 313).
In wintry driving conditions, always use winter
tyres (M+S tyres) and, if necessary, snow
chains. Only in this way will the driving safety
systems described in this section work as effec-
tively as possible. Driving safety systems
