During operation of the Climatronic, an increase in engine idle speed can oc-
cur under certain circumstances in order to ensure adequate heating comfort.
Climatronic - automatic mode
Read and observe
and on page 91 first.
The automatic mode is used in order to maintain a constant temperature andto demist the windows in the interior of the car.

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 is
nevertheless regulated.
Air distribution control
Read and observe
and on page 91 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.
Switching on/off
›
Press the button.
Heating and manual air conditioning system
If the air distribution control is set to position when the recirculation modes
is switched on, the recirculated-air mode is switched off. Recirculated air mode
can be switched on again from this setting by repeatedly pressing the symbol
button .
Climatronic
With the recirculated-air mode switched on the symbol appears in the dis-
play.
The symbol disappears from the display after turning off the air recircula-
tion.
Depending on the moisture conditions in the vehicle interior the air recircula-
tion may shut-down automatically.WARNINGThe recirculation system cannot be switched on for a longer period of time,
because there is no supply of fresh air from the outside. “Stale air” may re-
sult in fatigue in the driver and occupants, reduce attention levels and also
cause the windows to mist up. The risk of having an accident increases.
Switch off recirculated air mode as soon as the windows start to mist up.
CAUTION
We recommend not smoking in the vehicle when the recirculating air operation
is switched on. The smoke sucked from inside the vehicle is deposited on the
evaporator of the air conditioner. This produces a permanent odour when the
air conditioning system is operating which can only be eliminated through con-
siderable effort and expense (replacement of compressor).
Note
If recirculated air mode is switched on for around 15 minutes, the symbol
will begin to flash in the Climatronic display as a sign that the recirculated air
mode is switched on long-term. If the recirculated air mode is not switched off,
the symbol flashes for around 5 minutes.93Heating and ventilation

Automatic Braking
If the driver fails to respond to the acute warning, the system starts to apply
the brakes automatically with increasing stopping power in several stages.
Brake assist
If the driver brakes inadequate with an impending collision, the system auto-
matically increases braking force.
The braking assistance only occurs as long as the brake pedal is being firmly
pressed down.
Note
■ If an automatic brake intervention is triggered by the system, the pressure in
the brake system increases and the brake pedal cannot be operated with the
normal pedal stroke.■
The automatic braking interventions can be cancelled by pressing the accel-
erator pedal or by steering intervention.
