Useful information
i This Owner's Manual describes all models
and all standard and optional equipment
available to your vehicle at the time of pub-
lication of the Owner's Manual. Country-
specific deviations are possible. Please
note that your vehicle may not be equipped

Important safety notes
Fo rreasons of safety, Mercedes-Benzr ecom-
mends that you drive with the lights switched
on even during the daytime. In some coun-
tries, operation of the headlamps varies due
to legal requirements and self-imposed obli-
gations. Notes on driving abroad
To convert to symmetrical dipped beam
when driving abroad: switch the headlamps
to symmetrical dipped beam in countries in
which traffic drives on the opposite side of the
road to the country where the vehicle is reg-
istered. This prevents glare to oncoming traf-
fic. When using symmetrical lights, the edge
of the carriageway is not lit as widely and as
far ahead as normal.
Convert the headlamps as close to the border
as possible before driving in these countries
(Y page 245).
Convert to asymmetrical dipped beam
after returning: convert the headlamps back
to asymmetrical dipped beam as soon as pos-
sible after crossing the border when returning
(Y page 245). If the headlamps are converted to symmetri-
cal dipped beam, the "motorway mode" and
"extended range foglamps" functions (Intelli-
gent Light System) are not available. Light switch

Important safety notes
Xenon bulbs G
DANGER
Xenon bulbs are under high voltage. If you
touch the electrical contacts of a xenon bulb,
you could suffer an electric shock and be seri-
ously or even fatally injured. For this reason,
do not remove the cover of xenon bulbs.
Do not change the xenon bulbs yourself, but
have them replaced at a qualified workshop.
If your vehicle is equipped with xenon bulbs,
you can recognise 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 There are bulbs other than the xenon bulbs
that you cannot replace. Replace only the
bulbs listed (Y
page 130). Have the bulbs that
you cannot replace yourself changed at a
qualified specialist workshop.
If you require assistance changing bulbs, con-
sult a qualified specialist workshop.
Do not touch the glass tube of new bulbs with
your bare hands. Even minor contamination
can burn into the glass surface and reduce
the service life of the bulbs. Always use a lint- Changing bulbs

Important safety notes G
WARNING
Exhaust fumes are produced when the auxili-
ary heating is in operation. Inhaling these
exhaust fumes can be poisonous. You should
therefore switch off the auxiliary heating in
confined spaces without an extraction sys-
tem, e.g. a garage. G
WARNING
When operating the auxiliary heating parts of
the vehicle can get very hot. Make sure that
the exhaust system does not under any cir-
cumstances come into contact with easily
ignitable material such as dry grass or fuels.
The material could otherwise ignite and set
the vehicle alight. Choose your parking spot
accordingly.
Operating the auxiliary heating is thus pro-
hibited at filling stations or when your vehicle
is being refuelled. You must therefore switch
off the auxiliary heating at filling stations.
! Operating the auxiliary heating/ventila-
tion draws on the vehicle battery. After you
have heated or ventilated the vehicle a
maximum of two times, drive for a longer
distance.
i Switch on the auxiliary heating regularly,
e.g. for about ten minutes every month.
The auxiliary heating heats the air in the vehi-
cle interior to the set temperature without
using the heat of the running engine. The aux-
iliary heating is operated directly using the
vehicle's fuel. For this reason, the tank con-
tent must be at least at reserve fuel level to
ensure that the auxiliary heating functions.
The auxiliary heating/ventilation automati-
cally adjusts to changes in temperature and
weather conditions. For this reason, the aux-
iliary heating could switch from ventilation
mode to heating mode or from heating mode
to ventilation mode. Operating the climate control system
145Climate control Z

The auxiliary heating switches off automati-
cally after 50 minutes. This time limit can be
altered. Please contact a qualified specialist
workshop for this purpose.
You cannot use the auxiliary ventilation to
cool the vehicle interior to a temperature
lower than the outside temperature.
Before switching on X
Turn the key to position 2in the ignition
lock.
X Set the temperature.
The auxiliary heating/ventilation can be acti-
vated even when the climate control is being
controlled manually. Optimum comfort can
be attained when the system is set to auto-
matic mode. Set the temperature to 22 †.
The auxiliary heating/ventilation can be acti-
vated or deactivated using the remote control
or the button on the centre console.
The on-board computer can be used to spec-
ify up to three departure times, one of which
may be preselected (Y page 247).

contac taqualified specialist workshop.
The remote control has a maximum range of
approximately 300 metres. This range is
reduced by:
R sources of radio interference
R solid objects between the remote control
and the vehicle
R the remote control being in an unfavoura-
ble position in relation to the vehicle
R transmitting from an enclosed space
i The optimum range can be achieved if you
hold the remote control vertically, pointing
