XTension Top Tether belt=. Always comply
with the child restraint system manufactur-
er's installation instructions when doing so.
XMove head restraint back down again slightly if necessary (Ypage 75). Make sure that
you do not interfere with the correct routing of
Top Tether belt =.
BabySmart™ air bag deactivation sys-
tem
The BabySmart™ air bag deactivation system's
sensor system in the front-passenger seat
detects whether a special Mercedes-Benz child
restraint system with a transponder for the
BabySmart™ air bag deactivation system has
been installed. In this case, the PASSENGER AIR
BAG OFF indicator lamp lights up and remains
lit. The front-passenger front air bag is deacti-
vated.
When the SmartKey is removed from the ignition
lock or is in position 0, the PASSENGER AIR BAG
OFF indicator lamp is not lit.
iIf the front-passenger front air bag is deac-
tivated by the BabySmart™ air bag deactiva-
tion system, the following remain enabled on
the front-passenger side:
Rthe side impact air bag
Rthe pelvis air bag
Rthe window curtain air bag
Rthe Emergency Tensioning Device
GWARNING
If you secure a child in a child restraint system on the front-passenger seat and the
PASSENGER AIR BAG OFF indicator lamp is
off, the front-passenger front air bag can
deploy in the event of an accident. The child
could be struck by the air bag. This poses an
increased risk of injury or even fatal injury.
Make sure that the front-passenger front air
bag has been disabled. The PASSENGER AIR
BAG OFF indicator lamp must be lit.
GWARNING
If the PASSENGER AIR BAG OFF indicator
lamp is lit, the front-passenger front air bag is
deactivated. It will not be deployed in the
event of an accident and cannot perform its
intended protective function. A person in the
front-passenger seat could then, for example, come into contact with the vehicle's interior,
especially if the person is sitting too close to
the dashboard. This poses an increased risk of
injury or even fatal injury.
In this case the front-passenger seat may not
be used. You may only transport a child on the
front-passenger seat if they are seated in a
suitable rearward or forward-facing child
restraint system. Always observe the child
restraint system manufacturer's installation
instructions.
GWARNING
If you secure a child in a forward-facing child
restraint system on the front-passenger seat
and you position the front-passenger seat 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-passenger seat as far back as
possible. Always make sure that the shoulder belt strap is correctly routed from the vehicle
belt sash guide to the shoulder belt guide on
the child restraint system. The shoulder belt
strap must be routed forwards and down-
wards from the belt sash guide. If necessary,
adjust the belt sash guide and the front-
passenger seat accordingly. Always observe
the information about suitable positioning of
the child restraint system in this Operator's
Manual as well as the child restraint system
manufacturer's installation instructions.

Replacing bulbs
Important safety notes
GDANGER
Xenon bulbs carry a high voltage. You can get an electric shock if you remove the cover of
the Xenon bulb and touch the electrical con-
tacts. There is a risk of fatal injury.
Never touch the parts or the electrical con-
tacts of the Xenon bulb. Always have work on
the Xenon bulbs carried out at a qualified spe-
cialist workshop.
GWARNING
Bulbs, lamps and connectors can get very hot
when operating. If you change a bulb, you
could burn yourself on these components.
There is a risk of injury.
Allow these components to cool down before
changing a bulb.
Do not use a bulb that has been dropped or if its
glass tube has been scratched.
The bulb may explode if:
Ryou touch it
Rit is hot
Ryou drop it
Ryou scratch it
Only operate bulbs in enclosed lamps designed
for that purpose. Only install spare bulbs of the same type and the specified voltage.
Marks on the glass tube reduce the service life
of the bulbs. Do not touch the glass tube with
your bare hands. If necessary, clean the glass
