WARNING■For your own safety and that of other road users, ensure that all the win-
dows are free of ice, snow and misting. The blower should always be on to
prevent the windows from misting up.■
Under certain circumstances, air at a temperature of about 5 °C can flow
out of the vents when the cooling system is switched on.
CAUTION
■ The air inlet in front of the windscreen must be free from ice, snow or leaves,
for example, to ensure that the heating and cooling system works 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.

After the cooling system is switched off, only the ventilation function remains
active, whereby the lowest temperature that can be reached is the outside
temperature.
Setting temperature
The temperature can be set between +16 °C and +29 °C. The temperature is
regulated automatically within this range.
If illuminates in the display, then the Climatronic works with
maximum cool-
ing (temperature setting below +16 °C).
If illuminates in the display, then the Climatronic works with
maximum heat-
ing (temperature setting above +29 °C).
There is no automatic temperature control in the two end positions.

WARNING■
Do not switch off the Climatronic system for longer than necessary.■Switch on the Climatronic system as soon as the windows mist up.
CAUTION
Do not cover the interior temperature sensor 11 » Fig. 100 as this could impair
the functioning of the Climatronic. 101188Using the system

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 operation
Read and observe
and on page 87 first.
The automatic mode is used in order to maintain a constant temperature and
to demist the windows in the interior of the car.
To switch on press the
button. The display shows
(pos.

» Fig. 100
on page 88 ).
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 87 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.

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.89Heating and ventilation

With the key in the ignition, the ignition can be switched on and off and the
engine can be started / stopped.
WARNING■ While driving with the engine stopped, the ignition must always be
switched on » page 92, Turn ignition on / off and start the engine .
■ With the ignition off, the steering may lock » page 92 - danger of an
accident!■
Do not withdraw the ignition key from the ignition lock until the vehicle
has come to a stop » page 99, 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 164 .
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 91 first.
The electronic immobiliser (hereinafter referred to as immobiliser) makes theattempted 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 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.

Note
■ The engine running noises may louder at first be louder for a short time after
starting the cold engine. This is quite normal and is not an operating problem.■
You should not switch on any major electrical components during the heat-
ing period otherwise the vehicle battery will be drained unnecessarily.

CAUTION
Do not switch the engine off immediately at the end of your journey after the
engine has been operated over a prolonged period at high loads but leave it to
run at an idling speed for about 1 minute. This prevents any possible accumula-
tion of heat when the engine is switched off. 92Driving
