Climatronic* (automatic air conditioning)Description The Climatronic system is a combin
ation of an automatic heating,
fresh air and cooling system which provides optimal comfort for the occupants of the car.The Climatronic maintains fully automatically a convenience temperature. This is achieved by automatically varying the temperature of the outflowing air, the blower stages and the air distribution. The system also takes into account sunlight which eliminates the need to alte
r the settings manually. The
automatic mode
⇒ page 110 ensures maximum wellbeing of th
e occupants at all times of the year.
Description of Climatronic system The cooling operates only if the following conditions are met:•
engine running,
•
outside temperature above approx. +2°C,
•
switched on.
The AC compressor is switched off at a hi
gh coolant temperature in order to provide
cooling at a high load of the engine. Recommended setting for al
l periods of the year:
•
Set the desired temperature, we recommend 22 °C.
•
Press the button
⇒fig. 128
.
•
Move the air outlet vents
2 and
3 so that the air flow is directed slightly upwards.
Aeration of the vehicle when ignition is switched off* On vehicles fitted with power sliding/tilting roof with solar cells* the fresh air blower is automatically switched over to “solar mode” if the sun rays are sufficient after switching off the ignition. The solar
cells on the sliding/tilting roof deliver
power for the fresh air blower
. This supplies the interior of the car with fresh air.
For an optimum ventilation, the air outlet vents
2 and
3 must be opened
⇒ page 105, fig. 125
.
The ventilation functions only when the sliding/tilting roof is closed.
Note
On vehicles equipped with a
factory-fitted radio* or navi
gation*, the information of
the Climatronic is also shown on the display. This function can be switched off, see operating instructions of the ra
dio* or the navigation system*.

Technical Data
You can set the interior temperature between +18°C and +26°C. The interior temperature is regulated automatically with
in this range. If you chose a tempera-
ture lower than +18°C, a blue symbol lights
up at the start of the numerical scale. If
you chose a temperature higher than +26°C,
a red symbol lights up at the end of
the numerical scale. In both limit positio
ns the Climatronic operates at maximum
cooling or heating capacity, respectively. Th
e temperature is not controlled in this
case. 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 air 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 switch on the air distribution control
automatically when there is a nauseating 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
⇒page 109, fig. 128
.
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).

Auxiliary heating (auxiliary heating and ventilation)*Description and important information The auxiliary heating (auxiliary heating and ventilation) heats or supplies the interior of the vehicle with fresh air independent of the engine.Auxiliary heating (auxiliary heating) The auxiliary heating (auxiliary heating) func
tions 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 (e.g. during the heating phase of the engine). The auxiliary heating (auxiliary heating)
warms up the coolant during the combus-
tion of fuel from the vehicle tank. The cool
ant warms up the air, which (if the blower
speed is not set to zero) flows
into the occupant compartment.
Auxiliary ve
ntilation
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).
WARNING
•
The auxiliary heating must never be op
erated in closed rooms - risk of
poisoning!•
The auxiliary heating must not be runn
ing during refueling - risk of fire.
•
The exhaust pipe of the auxiliary heating is located on the underside of
the vehicle. Therefore do not place th
e vehicle, if you wish to operate the
auxiliary heating, in su
ch a way that the exhaust gases of the auxiliary
heating can come easily into contact
with inflammable materials (e.g. dry
grass) or easily inflammable su
bstances (e.g. fuel run out).

towards the top. You must not cover over the antenna with the
fingers or the palm of th
e hand. Obstacles between the radio remote control and
the vehicle, bad weather co
nditions and a weaker batt
ery can clearly reduce the
range. The auxiliary heating can only be switched
on or off with the radio remote control,
if the distance between the radio remote
control and the vehicle is at least 2 m.
Warning light in the radio remote control The warning light in the radio remote control
⇒fig. 131

.
Position
Move the steering wheel back and forward a little if the ignition key cannot, or cannot easily be turned into
this position, in order to
release the steering lock.
Position
The engine is started in this position. At
the same time switched on low beam or
main beam or other electrical compon
ents with major power consumption are
briefly switched off. The ignition key
moves back into position when one
releases the key. The ignition key must be turned back into position each time before starting the engine again. The starter repeat lock in th
e ignition lock prevents the starter being
engaged when the engine is r
unning and thus getting damaged.

P.
WARNING
•
When driving, the ignition key must always be in the position (igni-
tion switched on) without the engine running. This position is indicated by the warning lights coming on. If this is not the case, it could result in unex- pected locking of the steerin
g wheel - risk of accident!
•
Only remove the ignition key from the ignition lock when the vehicle has
come to a standstill (by applying the handbrake or moving the selector lever into the position P). The steering lock
can engage immediately - risk of acci-
dent!•
Always withdraw the ignition key if
you are going to leave the vehicle,
even for a short time. This is particularly important if children are left in the vehicle. The children might
otherwise start the engine
or switch on electrical
equipment (e.g. power windows) - risk of accident or injury!
