(the indi-
cator light in the button is lit).
At a temperature setting below 18 ° C at the start of the numerical scale, the
symbol will illuminate, Climatronic is using
Maximum cooling performance.
At a temperature setting above 26 ° C at the end of the numerical scale, the
symbol will illuminate, Climatronic is using
maximum heat output.
There is no automatic temperature control in the two end positions. In the
range between 18 °C to 26 °C, an automatic temperature control takes place.
Controlling blower
The Climatronic system controls the blower stages automatically in line with
the interior temperature. However, the blower stages can be manually adap-
ted to suit your particular needs.
If the blower speed is reduced to a minimum, Climatronic is switched off.
The set blower speed is displayed above the button
when the respective
number of indicator lights come on.
CAUTION
Do not cover the interior temperature sensor H » Fig. 116 - the function of the
Climatronic could be impaired.
Note
■ If the windscreen mists up, press the button . Press the button once
the windscreen has demisted.■
In order to ensure adequate thermal comfort, there may be an increase in en-
gine idle speed during operation of the Climatronic in some circumstances.
Climatronic - automatic operation
Read and observe
on page 94 first.
The automatic mode is used in order to maintain a constant temperature and
to demist the windows in the interior of the car.
If the warning light in the top right corner of the button
lights up, the Cli-
matronic operates in “HIGH”-mode.
Upon pressing the
button again, the Climatronic switches to “LOW”-mode
and the indicator light in the top left corner lights up. The Climatronic uses on-
ly in this mode the lower blower speed. However taking into account the noise
level, this is more comfortable, yet be aware that the effectiveness of the air
conditioning system is reduced particularly if the vehicle is fully occupied.
By pressing the button
again, it is changed to “HIGH”-mode.
Automatic mode can be switched off by pressing one of the buttons for the air
distribution or by increasing/decreasing the blower speed. The temperature
regulation is continued.
Note
Climatronic is set to the “HIGH” mode at the factory.95Heating and ventilation

The Climatronic can have a sensor that measures the air recirculation mode
and automatically turns on if there is an increased concentration of pollutants
in the incoming air.
When the pollutant concentration decreases to the normal level, the recircula-
ted air mode is automatically switched off.
If the air quality sensor does not automatically switch on the recirculated air mode, you can switch it on yourself by pressing the button . The indicator
light lights up in the button on the left side.
To turn off the air recirculation or to deactivate the automatic air recircula-
tion , press the
button of press the
symbol button repeatedly until the
warning lights in the button go out.
WARNINGThe recirculation system cannot be switched on for a longer period of time,
because no fresh air is fed through from the outside. “Stale air” may result
in fatigue in the driver and occupants, reduce attention levels and also
cause the windows to mist up. As soon as windows mist up, turn on the re-
circulation system immediately - There is a risk of accident!CAUTIONWe recommend not smoking in the vehicle when the recirculating air operation
is switched on. The smoke sucked from the interior is deposited on the evapo-
rator of the air conditioner. This produces a permanent odour when the air
conditioning system is operating which can only be eliminated through consid-
erable effort and expense (replacement of compressor).
Note
The Climatronic automatic air distribution control operates only if the outside
temperature is higher than approx. 2 °C.

The aux. heating heats the vehicle interior as well as the engine. For heating,
fuel is consumed from the fuel tank.
The auxiliary ventilation enables fresh air to flow into the vehicle interior with
the engine switched off, whereby the interior temperature is effectively de-
creased (e.g. with the vehicle parked in the sun).
The aux. heating (aux. heating and ventilation) (referred to just as aux. heating in the following) ensures the heating / ventilation depending on the setting of the air conditioning and the air outlet vents before switching off the ignition.
WARNING■ The auxiliary heating must never be operated in closed rooms (e.g. garag-
es) – There is a risk of poisoning!■
The auxiliary heating must not be allowed to run during refuelling – risk
of fire.
■
The exhaust pipe of the auxiliary heating is located on the underside of
the vehicle. If you want to use the auxiliary heating, do not park the car in
places where the exhaust fumes can come into contact with flammable
materials such as dry grass, undergrowth, leaves, spilled fuel etc. - risk of
fire.
CAUTION
The air inlet in front of the windscreen must be free (e.g. of ice, snow or
leaves) to ensure that the auxiliary heating operates properly. 97Heating and ventilation

Note■The aux. heating only switches the blower on, if it has achieved a coolant
temperature of approx. 50 °C.■
In the engine compartment, water vapour may form during the operation of
the aux. heating.

Depending on equipment fitted, it is possible to switch the ignition on/off and
start/stop the engine with the key in the ignition or using the starter button .
WARNING■
Never switch off the engine before the vehicle is stationary – There is a
risk of accident!■
While driving with the engine stopped the ignition must always be
switched on. Otherwise, the steering may lock - There is a risk of an acci-
dent!
■
Do not withdraw the ignition key from the ignition lock until the vehicle
has come to a stop » page 105, Parking . Otherwise, the steering may lock -
danger of an accident!
■
Never leave the vehicle unattended with the engine running - there is a
risk of theft etc!
■
Never (e.g. in garages) run the engine in a closed place - there is a risk of
poisoning and death!
CAUTION
■ Only start the engine when the engine and the vehicle are stationary - there
is a risk of starter and engine damage!■
Do not push-start the engine – There is a risk of damaging the engine and
the catalytic converter! The battery from another vehicle can be used as a
jump-start aid.
■
On vehicles with the starter button, pay attention to where the key is loca-
ted. The system can recognize the valid key, even if it has been accidentally
left on the vehicle roof - there is danger of loss or damage to the key!
NoteDo not warm up the engine while the vehicle is stationary. If possible, start
your journey as soon as the engine has started. Through this, the engine rea-
ches its operating temperature faster.
Electronic immobiliser and steering lock
Read and observe
and on page 100 first.
The electronic immobilizer (hereafter referred to as immobilizer) makes the
theft or unauthorised use of your vehicle more difficult.
Immobilizer
The immobilizer allows the engine to start provided an original vehicle key only
is used.
Malfunction of the immobilizer
If a component in the immobiliser key fails, it is not possible to start the en-
gine. A corresponding message appears in the display of the instrument clus-
ter to explain the immobiliser is active.
To start, use the other vehicle key or seek help from a specialist garage.

START-STOPsystem
Introduction
This chapter contains information on the following subjects:
Operation
102
Manually deactivating/activating the system
103The START STOPsystem (hereinafter referred to as the system) reduces
CO 2emissions and harmful emissions, and saves fuel.
If the system determine that the engine is not needed when the vehicle stops
(e.g. at the traffic lights), it turns off the engine and starts it again when mov-
ing off.
The system function depends on many factors. Some of them are down to the
driver, the others are systemic and can neither be influenced nor identified.
Therefore the system may react differently in situations which seem identi-
cal from the driver's perspective.
The system is automatically activated every time the ignition is switched on
(even where this has previously been manually deactivated with the button ).
Note
If the engine has stopped due to the system, the ignition remains on.
