passenger seat
General notes Accident statistics show that children
secured in the rear seats are safer than chil-
dren secured in the front-passenger seat. For
this reason, Mercedes-Benz strongly advises
that you install a child restraint system on a
rear seat.
Vehicles with the automatic front-passenger
front airbag deactivation system: if it is abso- lutely necessary to fit a child restraint system
to the front-passenger seat, always observe
the information on the "Automatic front-
passenger front airbag deactivation system"
(Y page 51).
You can thus avoid the risks that could arise
as a result of:
R a child restraint system that is not detected
by the automatic front-passenger front air- bag deactivation system
R the unintentional disabling of the front-
passenger front airbag
R the unsuitable positioning of the child
restraint system, e.g. too close to the dash-
board Children in the vehicle

Please observe the warning notice on the
front-passenger sun visor, see the illustra-
tion. G
WARNING
If you secure a child on the co-driver's seat in a rearward-facing child restraint system and
the PASSENGER AIR BAG ON indicator lamp
lights up, the co-driver's airbag could be
deployed in the event of an accident. The childcould be struck by the airbag. There is an
increased risk of injury, possibly even fatal.
In this case, always ensure that the co-driver's
airbag is disabled. The PASSENGER AIRBAG
OFF indicator lamp must light up.
NEVER use a rearward facing child restraint
on a seat protected by an ACTIVE AIRBAG in
front of it; DEATH or SERIOUS INJURY to the
CHILD can occur.
If the PASSENGER AIR BAG ON indicator lamp
is lit, the front-passenger front airbag is ena-
bled (Y page 43).
Vehicles without the automatic front-
passenger front airbag deactivation
system If the front-passenger seat of your vehicle is
not equipped with the automatic front-
passenger front airbag deactivation system,
this is indicated by a special sticker. The
sticker is affixed to the side of the dashboard
on the front-passenger side. The sticker is
visible when you open the front-passenger
door. Always fit the rearward-facing restraint sys-
tem to a suitable rear seat in this case
(Y
page 65).
Observe the following information under
"Rearward-facing child restraint system" and
"Forward-facing child restraint system" as
well as information on the suitable position-
ing of the child restraint system
(Y page 65).
Rearward-facing child restraint system If it is absolutely necessary to fit a rearward-
facing child restraint system to the front-
passenger seat, always make sure that the
front-passenger front airbag is disabled. Only
if the PASSENGER AIR BAG OFF indicator
lamp is lit continuously (Y page 43) is the
front-passenger front airbag disabled.
Always observe the information on suitable
positioning of the child restraint system
(Y page 65) in addition to the child restraint
system manufacturer's installation and oper-
ating instructions.
Forward-facing child restraint system If you secure a child in a forward-facing child
restraint system on the front-passenger seat,
always move the front-passenger seat as far
back as possible. Fully retract the seat cush-
ion length. The entire base of the child
restraint system must always rest on the seat cushion of the front-passenger seat. The
backrest of the child restraint system must,
as far as possible, lie flat against 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. Always make
sure that the shoulder belt strap is correctly
routed from the front-passenger seat-belt
extender 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 front-passenger
seat. 64

General notes The Intelligent Light System is a system that
adjusts the headlamps automatically to suit
the prevailing driving and weather conditions.
It offers advanced functions for improved illu-
mination of the road surface, e.g. depending
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 "Intelligent
Light System" function using the on-board
computer (Y page 262). Active light function The active light function is a system that
moves the headlamps according to the steer-
ing movements of the front wheels. In this
way, relevant areas remain illuminated while
you are driving. This allows you to recognise
pedestrians, cyclists and animals.
Active: when the lights are switched on
Cornering light function The cornering light function improves the illu-
mination of the road over a wide angle in the direction you are turning, enabling better vis-
ibility in tight bends, for example. It can only
be activated when the dipped-beam head-
lamps are switched on.
Active:
R if you are driving at speeds below 40 km/h
and switch on the turn signal or turn the
steering wheel
R if you are driving at speeds between
40 km/ha nd 70 km/h and turn the steer-
ing wheel Exterior lighting
