Air distribution controlRead and observe
and on page 119 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 and off
›
Press the button.
When the recirculation mode is activated, the warning light below the button
lights up.
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 position by repeatedly pressing the symbol
key .
When the is switched on and the temperature regulator is turned to the
left, the recirculated-air mode is switched on.
Climatronic
Climatronic may have an air quality sensor for the detection of the pollutant
concentration in the sucked-in air.
If a considerable increase in concentration of pollutants is recognised by the
air quality sensor, recirculated air mode will temporarily be switched on.
When the pollutant concentration decreases to the normal level, the recircula-
ted air mode is automatically switched off.
This automatic on/off switching of the recirculated-air mode can be activated
or deactivated in the Infotainment » Owner´s Manual Infotainment , chap-
ter Setting the heating and the cooling system .
If the button is pressed when the recirculation modes is switched on, the
recirculated-air mode is switched off.
Depending on the moisture conditions in the vehicle interior the air recircula- tion may also 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
The automatic activation/deactivation of the air recirculation with Climatronic
only works if the outside temperature is higher than approx. 2 °C.

122Using the system
WARNING■The auxiliary heating (auxiliary heating and ventilation) (following as aux.
heating) must never be operated in closed rooms (e.g. garages) – 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 heater, do not switch off the car in pla-
ces where the exhaust fumes can come into contact with flammable mate-
rials such as dry grass, undergrowth, leaves, spilled fuel etc. -. risk of fire.
CAUTION
■ The exhaust pipe of the auxiliary heating, which is located on the underside
of the vehicle, must not be clogged and the exhaust flow must not be blocked.■
If the auxiliary heating is running, the vehicle battery discharges.
■
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.
Note
■ The auxiliary heating only switches the blower on, if it has achieved a coolant
temperature of approx. 50 °C.■
At low outside temperatures, this can result in a formation of water vapour in
the area of the engine compartment. This is quite normal and is not an operat-
ing problem.
■
So that warm air can flow into the vehicle interior after switching on the aux.
heating, you must maintain the comfort temperature normally selected by you,
leave the fan switched on and leave the air outlet vents in open. It is recom-
mended to put the air flow in the position
or

WARNING■ While driving with the engine stopped, the ignition must always be
switched on » page 127, Turn ignition on / off and start the engine .
■ With the ignition off, the steering may lock » page 127 - danger of an
accident!■
Do not withdraw the ignition key from the ignition lock until the vehicle
has come to a stop » page 134, Parking . Otherwise, the steering may lock -
danger of an accident!
■
Never leave the key in the vehicle when you exit the vehicle. Unauthor-
ized persons, such as children, for example, could lock the car, turn on the
ignition or start the engine - there is a danger of injury, accidents and dam-
age!
■
Never leave the vehicle unattended with the engine running - there is
risk of accident, damage or theft!
■
Never switch off the engine before the vehicle is stationary – risk of acci-
dent!
WARNING■ Never (e.g. in garages) run the engine in a closed place - there is the dan-
ger of poisoning and death!■
Do not leave any items (e.g. cloths or tools) in the engine compartment.
This presents a fire hazard and the risk of engine damage.
■
Never cover the engine with additional insulation material (e.g. with a
cover) – risk of fire!
CAUTION
■ Only start the engine when the engine and the vehicle are stationary - there
is a danger of starter and engine damage!■
Do not push-start the engine – risk of damaging the engine and the catalytic
converter. The battery from another vehicle can be used as a jump-start aid
» page 230 .
Note
Do 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 immobilizer
Read and observe
and on page 126 first.
The electronic immobiliser (hereinafter referred to as the immobiliser) makesthe attempted theft or unauthorised use of your vehicle more difficult.
An electronic chip is integrated in the head of the key. The immobiliser is deac-
tivated with the aid of this chip when the key is inserted in the ignition lock.
As soon as the ignition key is removed from the ignition lock, the immobiliser is
automatically activated.
Operational problems
If the immobiliser components in the key fail, it is not possible to start the en-
gine. A message appears in the display of the instrument cluster to explain
that the immobiliser is active.
To start, use the other vehicle key or seek help from a specialist garage.

Information messages

The 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
or is at a standstill (e.g. at the traffic lights), it turns off the engine and starts it
again when moving off.
The system function depends on many factors. Some of them are down to the
driver, while others are systemic and can neither be influenced nor identified.
For this reason, the system may react differently in situations which seem
identical from the driver's perspective.
The system is automatically activated every time the ignition is switched on
(even when it has previously been manually deactivated with the
button).
Note
If the engine has stopped due to the system, the ignition remains switched on.130Driving

Parking
134WARNING■ Greater physical effort is required for braking when the engine is switch-
ed off – risk of accident!■
During the braking procedure on a vehicle with manual transmission,
when the vehicle is in gear and at low revs, press the clutch pedal. Other-
wise, the functionality of the brake system may be impaired – risk of acci-
dent!
■
When leaving the vehicle never leave persons leave unattended in the
vehicle who could release the brake. The vehicle could then start to move –
risk of accident!
■
Observe the recommendations on the new brake pads » page 139, New
brake pads .
CAUTION
Never let the brakes slip with light pressure on the pedal if braking is not nec-
essary. This causes the brakes to overheat and can also result in a longer brak-
ing distance and excessive wear.
Information on braking
Read and observe
and on page 132 first.
Wear-and-tear
The wear of the brake pads is dependent on the operating conditions and driv-
ing style.
The brake pads wear more quickly if a lot of journeys are completed in towns
and over short distances or if a very sporty style of driving is adopted.
If operated under severe conditions , the thickness of the brake pads must be
checked by a specialist garage between service appointments as well.
