nfirm that the vehicle has been correctly
locked. If the vehicle is locked by
pressing the button and some doors or the boot lid are
not closed, the turn signal lights flash only after closing.
WARNING
If the vehicle is locked from the outsid
e and the safe securing system is acti-
vated, there must not be any person in the vehicle as it is then not possible to open either a door or a window from the inside. The locked doors make it more difficult for rescuers to get into
the vehicle in an emergency - hazard!
Note
•
Operate the radio remote control only when the doors and boot lid are closed
and you have visual co
ntact with the vehicle.
•
Once in the car, you must
not press the lock button
of the radio remote
control before inserting the key into the ignition lock in order to avoid the car being inadvertently locked and, in addition, the anti-theft alarm system* being switched on. Should this happen, press the unlock button
of the radio remote control.
Synchonisation of the remote controlIf the vehicle cannot be unlocked by actuatin
g the remote control system then it is
possible that the code in the key and the
control unit in the vehicle are no longer
synchronised. This can occur when the buttons on the radio-operated key are actu- ated a number of times outside of the operative range of the equipment or the battery on the remote control was replaced.

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. Fo
r 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 au
tomatic light control also apply to the
light which is switched on manually

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
Assistant
in the main menu of the Information display*
⇒page 26.
WARNING
If the cornering lights are defectiv
e, the headlights are automatically
lowered to the emergency position, wh
ich prevents a possible dazzling of
oncoming traffic. Thus the illuminated length of the road is shortened. Drive carefully and have the car inspected
immediately by a specialist garage.

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 mi
nutes at the highest blower stage - also
during the cold season of the year - in order to remove 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 inte-rior of the vehicle forms deposits in the
evaporator 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 (replace-ment of compressor).•
The used air streams out through the air removal openings in the luggage
compartment.•
On vehicles equipped with a factory-fitted radio* or navigation*, the informa-
tion of the Climatronic is also shown on th
e display. This function can be switched
off, see operating instructions of th
e radio* or the navigation system*.

Lengthy and uneven distribution of the air flow out of the vents (in particular at the leg area) and large differences in temperature, for example when getting out of the vehicle, can result in chills in sensitive persons.Recirculated air mode In recirculated air mode air is sucked
out of the interior of the vehicle
and then fed back into the interior. When the automatic air distribu-tion control is switched on, an air quality sensor measures the concentration of pollutants in the drawn-in air.Recirculated air mode prevents polluted air outside the vehicle from getting into the vehicle, for example when driving through a tunnel or when standing in a traffic jam. If a considerable increase in concentration of pollutants is recognized by the ai
r quality sensor, when the automatic
air distribution control is switched
on, the air distribution control will
temporarily be switched off. If the concentration of pollutants decreases to the normal level, the air distributi
on control is automatically switched
off so that fresh air can be guided into the vehicle interior. Switching recirculated air mode on – Press the button repeatedly until the warning light on the left
side of the button lights up.
Switch on automatic air distribution control – Press the button repeatedly until the warning light on the right
side of the button lights up.
Switch off automatic air distribution control temporarily – If the air quality sensor does not sw
itch on the air distribution control
automatically when there is a nausea
ting smell, you can switch it on
yourself by pressing the button *.
The warning light lights up in
the button on the left side.
Switching recirculated air mode off – Press the button or press the button repetitively, until the
warning lights in the button go out.
WARNING
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 acci- dent increases. Switch recirculated air mode off as soon as the windows begin misting up.
Note
•
If the windscreen mists up, press the button

After the windscreen has been demisted, press the button .•
The automatic air distribution control operates only if the outside temperature
is higher than approx. 2°C.Controlling blower There are a total of seven blower stages available.The Climatronic system controls the bl
ower stages automatically in line
with the interior temperature. You
can also, however, adapt the blower
stages manually to suit your particular needs. – Press again the button on the left side (reduce blower speed) or on
the right side (increase blower speed).
