Problems with automatic child seat recognition
Problem
Possible causes/consequences and
M
MSolutions The PASSENGER AIR
BAG OFF indicator
lamp on the centre con-
sole is lit. As
pecial Mercedes-Benz child restraint system with atrans-
ponder for automatic child seat recognition has been fitted to the
front-passenger seat. The front-passenger front airbag has there- fore been disabledasd esired. G
WARNING
There is no child restraint system fitted to the front-passenger
seat. Automatic child seat recognition is malfunctioning, for exam-
ple due to electronic devices on the front-passenger seat.
There is arisk of injury.
X Remove electronic equipment from the front-passenger seat,
e.g.:
R laptop
R mobile phone
R ac ard with atransponder, such as aski pass or access pass
If the PASSENGER AIR BAG OFF indicator lamp remains lit, the
front-passenger seat may not be used.
X Visit aqualified specialist workshop. The
6 restraint sys-
tem warning lamp
lights up and/or the
PASSENGER AIR BAG
OFF indicator lamp
does not light up briefly
when you switch the
ignition on. G
WARNING
Automatic child seat recognition is malfunctioning.
Do not install achild restraint system on the front-passenger seat.
It is recommended that you fit the child restraint system to asuit-
able rear seat.
X Visit aqualified specialist workshop.
X Please also refer to the notes about the restraint system warning
lamp (Y page 306). Suitable positioning of the child
restraint system
Introduction Only child restraint systems which are
approved in accordance with the ECE stand-
ard ECE R44 are permitted for use in the vehi- cle.
For certain child restraint systems in weight
categories 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".70

Distanc ewarnin gfunction General notes
The distance warning function can hel
pyou to
minimis ethe ris kofa collisio nwitht he vehi-
cle in front or reduce the effects of such a
collision. If the distance warning function
detects that there is ariskofa collision, you
will be warned visuall yand acoustically.
Important safety notes
i Observe the "Important safety notes" sec-
tion for driving safety systems (Y page 77).G
WARNING
The distance warning function doe snot react:
R to peopl eoranimals
R to oncoming vehicles
R to crossing traffic
R whe ncornering
Thus, the distance warning function cannot
provid eawarning in al lcritical situations.
There is ariskofana ccident.
Alway spaycareful attention to the traffic sit-
uation and be ready to brake. G
WARNING
The distance warning function cannot always
clearl yide ntif yobjects and comple xtraffic
situations.
In such cases, the distance warning function
may:
R giv eanu nnecessary warning
R not giv eawarning
There is ariskofana ccident.
Alway spaycareful attention to the traffic sit-
uation; do not rel yonthe distance warning
function alone. Function
The distance warning function issue
sawarn-
ing at speeds:
R of approximately 30 km/h or more ,if, over
several seconds, the distance maintained
to the vehicle travelling in front is insuffi-
cient. The ·distance warning lamp
then lights up in the instrument cluster.
R of approximately 7km/h or more ,ifyou
rapidly approach avehicle in front. An inter-
mittent warning tone will then sound and
the · distance warning lamp will light
up in the instrument cluster.
X Brake immediately in order to increas ethe
distance from the vehicle in front.
or
X Take evasiv eaction provided it is safe to do
so.
Due to the nature of the system, particularly
complicate dbutnon-critical driving condi-
tions may also cause the system to display a
warning.
With the hel pofthe radar sensor system, the
distance warning function can detect obsta-
cle sthat are in the path of your vehicle for an
extended period of time.
Up to aspeed of approximately 70 km/h ,the
distance warning function can also react to
stationary obstacles, such as stopped or
parked vehicles.
Autonomous braking function If the driver doe
snot react to the distance
warning signal in acritical situation, COLLI-
SION PREVENTIO NASSIST PLUS can assist
with the autonomous braking function.
The autonomous braking function:
R gives the driver more time to react to criti-
cal driving situations
R can hel pthe driver to avoid an accident or
R reduce sthe effects of an accident Drivin

General notes The Intelligent Light System is
asystem that
adjusts the headlamps automatically to suit
the prevailing driving and weather conditions.
It offers advanced functions for improved illu-

on the vehicle speed or weather conditions.
The system includes the active light function, cornering light function, motorway mode and
extended range foglamps. The system is only active when it is dark.
You can activate or deactivate the "IntelligentLight System" function using the on-board

Partial main-beam illumination is aformof
illumination whereby th emain beam is direc-
