Rain lights
If you switch on the windscreen wipe in th
e operation rain sensor* for longer than 10
seconds or in the operation permanent wipe (position 2 or 3) page 61 switching on
for longer than 15 seconds, the side lights and low beam are switched on automati-
cally. The light switches off if the windscreen wipe is in operation rain sensor* for more
than 4 minutes or is not switched on in the operation permanent wipe.
WARNING
The automatic light control only operat es as a support. The driver is not
released from his responsibility to inspect the light and if necessary to switch on
the light depending on the light conditions. The light sensor cannot detect for
example rain or snow. For these conditions we recommend to switch on the low
beam
!
Note
Do not affix any stickers in front of the light sensor, so that you do not impair its
function or put it out of operation.
The same principles as for using the automa tic light control also apply to the light
which is switched on manually page 51.
Cornering lights*The cornering lights are used to illuminate the curves by means of the cone of light
swiveling together with the front headlight with Xenon lights*. This function is active
when the speed of the car increases to more than 10km/h.
The swiveling function of the headlights ca n be switched off / on via the menu point
Assistants in the main menu of the information display* page 23.
WARNING

If the intermittent wipe is switched on, the intervals are also controlled depending on
speed.
The rain sensor* automatically regulates the break between the individual wiper
strokes depending on the intensity of the rain.
The rear window will be wiped again if the front window wipers are on when reverse
gear is selected.
The windscreen washer nozzles are heated* when the ignition is switched on.
Top up with wash liquid page 207.
Winter position
If the windscreen wipers are in rest positi on, they cannot be folded out from the wind-
screen. For this reason we recommend adjusting the windscreen wipers in winter so
that they can be folded out from the windscreen easily. You can set this rest position as
follows:
Switch on the windscreen wipers.
Switch off the ignition. The windscreen wipers remain in the position in which they
were when switching off the ignition.
You can also use the service position page 63 as a winter position.
WARNING
Properly maintained wind screen wiper blades are essential for clear visi-
bility and safe driving page 63.
Do not use the windscreen washer sy stem at low temperatures, without
heating the windscreen beforehand. Otherwise the window cleaner could
freeze on the windscreen and re strict the view to the front.
The rain sensor only operates as a support. The driver is not released from
the responsibility to set the function of the windscreen wipers manually
depending on the visibility conditions.
Caution
In frosty weather, please firs t of all check whether the windscreen wiper blades are not
frozen to the windscreen before switching them on. Switching on windscreen wipers
when the blades are frozen to the windscreen may result in damage both to the blades
and the motor of the windscreen wipers!
Note
If the slower or the faster wiper setting is switched on page 61, fig. 50 and
the vehicle speed decreases to below 4 km/h, the lower wiper step is switched on
automatically. At a speed increase of more than 8 km/h the previous wiper setting is
established again.
If there is an obstacle on the windscre en, the wiper will try to push away the
obstacle. If the obstacle continues to block the wiper, the wiper stops after 5 cycles, in
order to avoid a damage to the wiper. Re move the obstacle and and switch on the
wiper again.
Automatic rear window wiper* (Combi)If the windshield wiper lever is in the position page 61, fig. 50 or , the rear
window wiper carries out a wi ping process every 30 seconds or 10 seconds at a speed
above 5 km/h.
When the rain sensor* is active (the lever is in the position ) the function is only
active if the front window wipers continue to operate (no break between each wiping
process).

time and fifth time, the low beam or main beam are switched on and the windscreen
wiper lever was held in the position page 61, fig. 50 for about 1 second.
The headlight washer nozzles are moved forward out of the bumper by the water pres-
sure for cleaning the headlights.
You should remove stubborn dirt (such as in sect residues) from the headlight lenses at
regular intervals, for example when refuelling . Please refer to the following guidelines
page 188, “The headlight lenses”.
You should remove any snow from the fixtur es of the washer nozzles and clear ice in
winter with a de-icing spray in order to ensure proper operation of the cleaning
system.Replacing wiper blades for the windscreen wipersOne cannot fold out the wiper arms in the re st position from the windscreen. Before
replacing the wiper arms you must put them into the service position.
Service position for changing wiper blades– Close the bonnet.
– Switch the ignition on and then again off.
– Then press the windscreen wiper lever in the position page 61, fig. 50 within
20 seconds - the wiper arms move into the service position.Taking off the wiper blade– Fold windscreen wiper arm out from the windscreen and position the wiper blade at right angles to the wiper arm .
– Take off the wiper blade in direction of arrow fig. 51 .Attaching a wiper blade– Push the new wiper blade ov er the wiper arm and turn the wiper blade into the
vertical position.
– Check whether the wiper blade is correctly attached.
– Fold the windscreen wiper arms onto the window and switch on the ignition. By pressing the window wiper leve r into the sprung position fig. 51 or when
driving at a speed greater than 4 km/h, the windscreen wiper arms move back into
the rest position.
Wiper blades in proper condition are essentia l to obtain good visibility. Wiper blades
should not be allowed to become dirtied by dust, insect remains and preserving wax.
Juddering or smearing of the wiper blades co uld then be due to wax residues left on
the windscreen by vehicle wash ing in automatic vehicle wash systems. It is therefore
important to degrease the lips of the wiper blades after every pass through an auto-
matic vehicle wash system .
WARNING
The ignition must not be switched on if the front windscreen wiper arms are
folded out. The wiper blades would move back into their rest position and while
doing so damage the paintwork of the bonnet.
If the windscreen wipers are handled ca relessly, there is a risk of damage to
the windscreen.

outside temperature above approx. +2°C,
switched on.
If the cooling system is switched on, the temperature and air humidity drops in the
vehicle. The wellbeing of the occupants of the car is enhanced as a result of this partic-
ularly at high outside temperatures and a high air humidity. The system prevents the
windows misting up during th e cold season of the year.
The heating effect is dependent upon the c oolant temperature, thus full heat output
only occurs when the engine has reached its operating temperature.
It is possible to briefly activate recirculat ed air mode in order to enhance the cooling
effect page 103.
The air inlet in front of the windscreen must be free of ice, snow or leaves in order to
ensure that the heating and cooling systems operate properly.
The AC compressor is switched off at a hi gh coolant temperature in order to provide
cooling at a high load of the engine.
After switching on the cooling Condensation from the evaporator of the air condi-
tioning may drip down and form a puddle be low the vehicle. This is quite normal and
not an indication of a leak!
Recommended setting for all periods of the year:
Set the desired temperature, we recommend 22°C.
Press the button page 102, fig. 108 .
Move the air outlet vents 3 and 4 so that the air flow is directed slightly upwards.
WARNING
For your own safety and that of other road users, ensure that all the
windows are free of ice, snow and mistin g. Please familiarize yourself about
how to correctly operate th e heating and ventilation systems, how to demist
and defrost the windows, as well as with the cooling mode.
You should not leave recirculated air mode on over a longer period of time,
as “stale” air may result in fatigue in the driver and occupants, divert your
attention and also cause the windows to mist up. The risk of having an accident
increases. Switch recirculated air mode off as soon as the windows begin
misting up.
Note
If the cooling system has not been switched on for a lengthy period, odours may
be produced at the evaporator because of deposits. Switch the cooling system on at
least once a month for approximately 5 minu tes at the highest blower stage - also
during the cold season of the year - in order to avoid such odours. Also open a window
for a short time.
We recommend that you do not smoke in the vehicle when the recirculating air
mode is operating since the smoke which is drawn at the evaporator from the interior
of the vehicle forms deposits in the evapor ator of the air conditioning system. This
produces a permanent odour when the air conditioning system is operating which can
only be eliminated through considerable effort and expense (replacement of
compressor).
The used air streams out through the air removal openings in the luggage compart-
ment.
On vehicles equipped with a factory-fitted radio* or navigation*, the information
of the Climatronic is also shown on the display. This function can be switched off, see
operating instructions of the radio* or the navigation system*.

Controlling blower
There are a total of seven blower stages available.The Climatronic system controls the blower stages automatically in line with the inte-
rior temperature. You can also , however, a dapt the bl ower stages ma nua lly to suit y our
particular needs.
– Press again the button on the left side (reduce blower speed) or on the right side (increase blower speed).
If you switch off the blower, th e Climatronic is switched off.
The set blower speed is displayed above the button when the respective number
of warning lights come on.
WARNING
“Stale air” may result in fatigue in the driver and occupants, reduce atten-
tion levels and also cause the windows to mist up. The risk of having an accident
increases.
Do not switch the Climatronic system off for longer than necessary.
Switch the Climatronic system on as soon as the windows mist up.

The temperature control is controlled automatically. More air flows out of the air outlet
vents 1.Auxiliary heating (auxiliary heating and ventilation)*Description and important information
The auxiliary heating (auxiliary he ating and ventilation) heats or
supplies the interior of the vehicl e with fresh air independent of the
engine.Auxiliary heating (auxiliary heating)
The auxiliary heating (auxiliary heating) functions in connection with the Climatic or
Climatronic.
It can be used when stationary, when engi ne is switched off for preheating of the
vehicle as well as while driving (only during the heating phase of the engine).
The auxiliary heating (auxiliary heating) wa rms up the coolant during the combustion
of fuel from the vehicle tank. The coolant warms up the air, which (if the blower speed
is not set to zero) flows into the occupant compartment.
Auxiliary ventilation
The auxiliary ventilation enables fresh air to flow into the vehicle interior by switching
off the engine, whereby the interior temperature is effectively decreased (e.g. with the
vehicle parked in the sun).
