Important safety notes
G
WARNING
Bulbs, lamps and plug connectors can
become very hot during use. When replacing a bulb, you could burn yourself on these com-
ponents. There is a risk of injury.
Allow these components to cool down before replacing the 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 fit 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.
Only replace the bulbs listed (Y page 146).
Have the bulbs that you cannot replace your- self replaced at a qualified specialist work-
shop.
If you require assistance replacing bulbs, con-
sult a qualified specialist workshop.
If the new bulb still does not light up, consult
a qualified specialist workshop.
Headlamps and lights 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.
Vehicles with LED headlamps: the front
and rear light clusters of your vehicle are
equipped with LED light bulbs. Do not replace
the bulbs yourself. Contact a qualified spe-
cialist workshop which has the necessary
specialist knowledge and tools to carry out
the work required. Overview of bulb types
You can replace the following bulbs. The
details for the bulb type can be found in the
legend. Vehicles with halogen headlamps

Switching the windscreen wipers on/
off
! Do not operate the windscreen wipers
when the windscreen is dry, as this could
damage the wiper blades. Moreover, dust
that has collected on the windscreen can
scratch the glass if wiping takes place when the windscreen is dry.
If it is necessary to switch on the wind-
screen wipers in dry weather conditions,
always operate them using washer fluid. !
If the windscreen wipers leave smears on
the windscreen after the vehicle has been
washed in an automatic car wash, this may
be due to wax or other residue. Clean the
windscreen with washer fluid after an auto- matic car wash.
! Intermittent wiping with rain sensor: due
to optical influences and the windscreen
becoming dirty in dry weather conditions,
the windscreen wipers may be activated
inadvertently. This could damage the wind- screen wiper blades or scratch the wind-
screen.
For this reason, you should always switch
off the windscreen wipers in dry weather. 1

The perfume atomiser helps to improve driv-
ing comfort.
Using Audio 20 or COMAND Online, you can:
R switch the perfume atomiser on or off (see
the separate operating instructions)
R regulate the perfume intensity (see the sep-
arate operating instructions)
The following conditions can affect your per-
ception of the perfume intensity:

R time of year or day
R air humidity
R physiological condition of occupants, e.g.
fatigue or hunger
The perfume atomiser can only be operated
when the automatic climate control is
switched on and is only active when the glove compartment is closed.
The perfume atomiser is provided with a pre-
filled perfume vial. You can also choose from
a variety of filled perfume vials and an empty
vial which you can fill yourself.
If you refill an empty perfume vial, observe the separate information sheet attached to the
vial.

Important safety notes G
DANGER
If the exhaust pipe is blocked or sufficient
ventilation is not possible, toxic exhaust
fumes can enter the vehicle, especially car-
bon monoxide. This is the case, e.g. in
enclosed spaces, or if the vehicle is stuck in
snow. There is a risk of fatal injuries.
You should switch off the auxiliary heating in
enclosed spaces which do not have an extrac- tion system, e.g. a garage. If the vehicle is
stuck in snow and you must leave the auxiliary
heating running, keep the exhaust pipe and
the area around the vehicle clear of snow. To guarantee a sufficient supply of fresh air, open
a window on the side of the vehicle away from the wind. G
WARNING
When the auxiliary heating is switched on,
parts of the vehicle can become very hot.
Flammable materials such as leaves, grass or twigs may ignite if they come into contact
with:
R hot parts of the exhaust system
R the exhaust gas itself
There is a risk of fire. When the auxiliary heating is switched on,
make sure that:
R no flammable materials come into contact
with hot vehicle components
R the exhaust gas can escape from the
exhaust pipe unhindered
R the exhaust gas does not come into contact
with flammable materials.
The auxiliary heating is fitted under the front
wing on the right-hand side of the vehicle. The emissions outlet is found behind the front
wheel on the right-hand side of the vehicle.
! 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.
Switch the auxiliary heating on regularly once a month for about ten minutes.
The auxiliary heating heats the air in the vehi-
cle interior to the set temperature. This
occurs without using the heat of the running
engine. The auxiliary heating is operated
directly using the vehicle's fuel. For this rea-
son, the tank content must be at least at
reserve fuel level to ensure that the auxiliary
heating functions.
The auxiliary heating or auxiliary ventilation
automatically adjusts to changes in temper-
ature and weather conditions. For this rea-
son, the auxiliary heating could switch from
ventilation mode to heating mode or from
heating mode to ventilation mode.
The auxiliary heating switches off when the
engine is switched off. The auxiliary ventila-
tion is not active if the engine is running.
The auxiliary heating or auxiliary ventilation
switches off automatically after 50 minutes.
This time limit can be altered. To do this, visit a qualified specialist workshop.
You cannot use the auxiliary ventilation to
cool the vehicle interior to a temperature
lower than the outside temperature. 178
