WARNING■The blower should always be on to prevent the windows from misting.
Otherwise there is a risk of accident.■
Under certain circumstances, air at a temperature of about 5 °C can flow
out of the vents when the cooling system is switched on.
Note
■ The air inlet in front of the windscreen must be free of e.g. ice, snow or
leaves to ensure that the heating and cooling system operates properly.■
After switching on the cooling Condensation from the evaporator of the air
conditioning may drip down and form a puddle below the vehicle. This is not a
leak!
■
If the coolant temperature is too high, the cooling system is switched off to
ensure that the engine cools down.

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

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
Air distribution controlRead and observe
on page 94 first.
The recirculation mode prevents contaminated outside air getting into the in-
terior of the vehicle. In recirculated air mode air is sucked out of the interior of
the vehicle and then fed back into the interior.

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.

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

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.
