The PASSENGER AIR BAG ON indicator lamp
is inoperative. It lights up briefly when the
ignition is switched on and then goes out
again.
Depending on the person in the front-
passenger seat, the front-passenger front air
bag must either be disabled or enabled; see
the following points. You must make sure of
this both before and during a journey.
R Children in a child restraint system:
whether the front-passenger front air bag is enabled or deactivated depends on the
installed child restraint system, and the age
and size of the child. Therefore, be sure to
observe the notes on the "Occupant clas-
sification system (OCS)" (Y page 49) and
on "Children in the vehicle" (Y page 57).
There you will also find instructions on
backwards- and forwards-facing child
restraint systems on the front-passenger
seat.
R All other persons: depending on the clas-
sification of the person in the front-
passenger seat, the front-passenger front
air bag is enabled or deactivated
(Y page 49). Be sure to observe the notes
on "Seat belts“ (Y page 42) and "Air bags"
(Y page 46). There you can also find infor-
mation on the correct seat position. Seat belts
Introduction Seat belts are the most effective means of
restricting the movement of vehicle occu-
pants in the event of an accident or the vehi-
cle rolling over. This reduces the risk of vehi- cle occupants coming into contact with parts
of the vehicle interior or being ejected from
the vehicle. Furthermore, the seat belt helps
to keep the vehicle occupant in the best posi- tion in relation to the air bag. The seat belt system comprises:
R Seat belts
R Emergency Tensioning Devices and seat
belt force limiters
If the seat belt is pulled by the belt loop
quickly or with a jerky movement, the belt
retractor locks. The belt strap cannot be
extracted any further.
The Emergency Tensioning Device tightens
the seat belt in an accident, pulling the belt
close against the body. However it does not
pull the vehicle occupant back in the direction of the backrest.
The Emergency Tensioning Device does not
correct an incorrect seat position or the rout-
ing of an incorrectly fastened seat belt.
When triggered, seat belt force limiters help
to reduce the force exerted by the seat belt on the vehicle occupant.
The seat belt force limiters are synchronized
with the front air bags, which absorb part of
the deceleration force. This can reduce the
force exerted on the vehicle occupants during
an accident.
! If the front-passenger seat is unoccupied,
do not insert the belt tongue into the buckle of the front-passenger seat. This may oth-
erwise lead to the triggering of the Emer-
gency Tensioning Device in the event of an
accident, which will then need to be
replaced.
Important safety notes The use of seat belts and child restraint sys-
tems is required by law in:
R all 50 states
R the U.S. territories
R the District of Columbia
R all Canadian provinces
Even where this is not required by law, all
vehicle occupants should correctly fasten
their seat belts before starting the journey. 42

X Press the combination switch beyond the
pressure point in the direction of arrow 0043.
The 00CE indicator lamp in the multifunc-
tion display lights up when it is dark and the light sensor activates the low-beam head-
lamps.
If you are driving at speeds above approx-
imately 16 mph (25 km/h):
The headlamp range is set automatically
depending on the distance between the
vehicle and other road users.
If you are driving at speeds above approx-
imately 19 mph (30 km/h) and no other
road users have been detected:
The high-beam headlamps are switched on
automatically. The 0057indicator lamp in
the instrument cluster also lights up.
If you are driving at speeds below approx-
imately 16 mph (25 km/h) or other road
users have been detected or the roads are adequately lit:
The high-beam headlamps are switched off
automatically. The 0057indicator lamp in
the instrument cluster goes out. The 00CE
indicator lamp in the multifunction display
remains lit.
X To switch off: move the combination
switch back to its normal position or move
the light switch to another position.

Important safety notes
Xenon bulbs G
DANGER
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. If your vehicle is equipped with Xenon bulbs,
you can recognize this by the following: the
cone of light from the Xenon bulbs moves
from the top to the bottom and back again
when you start the engine. For this to be
observed, the lights must be switched on
before starting the engine.
Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure that these function correctly at all times.
Have the headlamp setting checked regularly.
Other bulbs G
WARNING
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:
R you touch it
R it is hot
R you drop it
R you scratch it
Only operate bulbs in enclosed lamps
designed for that purpose. Only install spare
bulbs of the same type and the specified volt- age.
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 tube when cold with alcohol or spirit and
rub it off with a lint-free cloth.
Protect bulbs from moisture during opera-
tion. Do not allow bulbs to come into contact
with liquids.
There are bulbs other than the Xenon bulbs
that you cannot replace. Replace only the
bulbs listed (Y page 115). Have the bulbs that
you cannot replace yourself changed at a
qualified specialist workshop. 114

flashes. The rear win-
dow defroster has
deactivated prema-
turely or cannot be acti- vated. The on-board voltage is too low because too many electrical con-
sumers are switched on.
X Switch off any consumers that are not required, e.g. reading
lamps, interior lighting or the seat heating.
When the battery is sufficiently charged, the rear window
defroster can be activated again. The roof is open.
X Close the roof.
When the roof is closed, the rear window defroster can be acti-
vated again. Activating/deactivating air-recircula-

General notes If you switch on air-recirculation mode, the
windows can fog up more quickly, in particu-
lar at low temperatures. Only use air-recircu-
lation mode briefly to prevent the windows
from fogging up.

activated at high levels of pollution (dual-
zone automatic climate control only) or at
high outside temperatures. When air-recir-
culation mode is activated automatically,
the indicator lamp in the 0072button is not
lit. Outside air is added after about
30 minutes.
X To deactivate: press the0072button.
The indicator lamp in the 0072button goes

General notes The residual heat function is only available on
vehicles for Canada.
It is possible to make use of the residual heat
of the engine to continue heating the station- ary vehicle for up to 30 minutes after the
engine has been switched off. The heating
time depends on the temperature that has
been set.
Depending on the equipment level, the con-
trol panel has either the 004Bbutton or the
0056 button. Operating the climate control systems

Important safety notes
G
WARNING
Very hot or very cold air can flow from the air vents. This could result in burns or frostbite in the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior. G
WARNING
When AIRSCARF is switched on, very hot air
can flow from the vents in the head restraints. This could result in burns in the immediate
vicinity of the air vents. There is a risk of injury.
Reduce the heater output before it becomes
too hot. In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior, please observe the following notes:
R keep the air inlet grille on the hood and in
the engine compartment on the front-
passenger side free of blockages, such as
ice, snow or leaves.
R never cover the air vents or air intake grilles
in the vehicle interior.
i You can move the adjusters for the air
vents vertically or horizontally to set the
direction of the airflow.
i For optimal climate control in the vehicle,
open the air vents completely and set the
adjusters to the central position. Setting the center air vents
