Climatronic (automatic air conditioning)*
Description
The Climatronic system is a combination of an automatic
heating, fresh air and cooling system which provides
optimal comfort for the occupants of the car.
The Climatronic maintains a constant temperature fully automatically,
once it has been set. This is achieved by automatically varying the
temperature of the outflowing air, the blower stages and the air distribu-
tion. The system also takes into account sunlight which eliminates the
need to alter the settings manually. The automatic mode ⇒ page 106
ensures maximum wellbeing of the occupants at all times of the year.
Description of Climatronic system
The cooling operates only if the following conditions are met:
•engine running,
•outside temperature above +2 °C,
•the button is not pressed.
If the cooling system is switched on, the temperature and air humidity
drops in the vehicle. The wellbeing of the occupants of the car is enhanced
as a result of this particularly at high outside temperatures and a high air
humidity. The system prevents the windows misting up during the cold
season of the year.
The heating effect is dependent upon the coolant temperature, thus full
heat output only occurs when the engine has reached its operating
temperature.
It is possible to briefly activate recirculated air mode in order to enhance
the cooling effect ⇒. The air inlet in front of the windscreen must be free of ice, snow or leaves
in order to ensure that the heating and cooling systems operate properly.
The AC compressor is switched off at a high coolant temperature in order
to provide cooling at a high load of the engine.
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 quite normal and not an indication of a leak!
Recommended setting for all periods of the year:
•Set the temperature to 22 °C.
•Press the button ⇒page 105, fig. 96 .
•Move the air outlet vents 3 and 4 so that the air flow is directed slightly
upwards ⇒page 108, fig. 97 .
Switching over between degrees Celsius and degrees Fahrenheit
Press and hold the buttons and ⇒page 105, fig. 96 . The
information in the desired temperature measuring unit appears in the
display.
WARNING
•For your own safety and that of other road users, ensure that all
the windows are free of ice, snow and misting. Please familiarize
yourself about how to correctly operate the heating and ventilation
systems, how to demist and defrost the windows, as well as with
the cooling mode.
•You should not leave recirculated air mode on over a longer
period of time, as “stale” air may result in fatigue in the driver and
occupants, divert your attention and also cause the windows to
mist up. The risk of having an accident increases. Switch recircu-
lated air mode off as soon as the windows begin misting up.

Note
•If the cooling system has not been switched on for a lengthy period,
odours may be produced at the evaporator because of deposits. Switch
the cooling system on at least once a month for approximately 5 minutes
at the highest blower stage - also during the cold season of the year - in
order to remove such odours. Also open a window for a short time.
•We recommend that you do not smoke in the vehicle when the recir-
culating air mode is operating since the smoke which is drawn at the evap-
orator from the interior of the vehicle forms deposits in the evaporator of
the air conditioning system. This produces a permanent odour when the
air conditioning system is operating which can only be eliminated through
considerable effort and expense (replacement of compressor).
•The used air streams out through the air removal openings in the
luggage compartment.

Defrosting windscreen - switching off
– Once again press the button or the button .
The temperature control is controlled automatically. More air flows out of
the air outlet vents 1 and 2.
Recirculated air mode
In recirculated air mode air is sucked out of the interior of
the vehicle and then fed back into the interior.
Recirculated air mode prevents polluted air outside the vehicle
from getting into the vehicle, for example when driving through a
tunnel or when standing in a traffic jam.
Switching recirculated air mode on
– Press button , the symbol
appears on the display.
Switching recirculated air mode off
– Once again press the button or the button , the symbol or the logo is no longer shown on the display.
WARNING
You should not leave recirculated air mode on over a longer period
of time, as “stale” air may result in fatigue in the driver and occu-
pants, divert your attention and also cause the windows to mist up.
The risk of having an accident increases. Switch recirculated air
mode off as soon as the windows begin misting up.
Note
If the windscreen mists up, press the button . After the windscreen has
been demisted, press the button .
Setting temperature
– You can set the desired interior temperature after switching on the ignition with the control dial .
You can set the interior temperature between +18°C and +29°C. The inte-
rior temperature is regulated automatically within this range. If you select
a temperature of less than +18 °C, “LO” is shown on the display. If you
select a temperature above +29 °C, “HI” is shown on the display. In both
limit positions the Climatronic operates at maximum cooling or heating
capacity, respectively. The temperature is not controlled in this case.
Lengthy and uneven distribution of the air flow out of the vents (in partic-
ular at the leg area) and large differences in temperature, for example
when getting out of the vehicle, can result in chills in sensitive persons.
Controlling blower
There are a total of seven blower stages available.
The Climatronic system controls the blower stages automatically
in line with the interior temperature. You can also, however, adapt
the blower stages manually to suit your particular needs.
– Turn the control dial ⇒page 105, fig. 96 to the left (reduce
blower speed) or right (increase blower speed).

Starting-off and Driving
Setting steering wheel position*You can set the height and the forward/back position of the
steering wheel to the desired position.
– Adjust the driver seat ⇒page 68.
– Pull the lever below the steering column ⇒fig. 98 down
⇒ .
– Set the steering wheel to the desired position (concerning height and forward/back position).
– Then push the lever up against the steering column until it locks into place.
WARNING
•You must not adjust the steering wheel when the vehicle is
moving!
•The driver must maintain a distance of at least 25 cm to the
steering wheel ⇒fig. 99 . Not maintaining this minimum distance
will mean that the airbag system will not be able to properly protect
you - hazard!
•For safety reasons the lever must always be firmly pushed up to
avoid the steering wheel altering its position unintentionally when
driving - risk of accident!
•If you adjust the steering wheel further towards the head, you
will reduce the protection offered by the driver airbag in the event
of an accident. Check that the steering wheel is aligned to the
chest.
•When driving, hold the steering wheel with both hands firmly on
the outer edge in the 9 o'clock and 3 o'clock position. Never hold

the steering wheel firmly in the 12 o'clock position or in another
way (e.g. in the middle of the steering wheel or at the inner steering
wheel edge). In such cases, injuries to the arms, the hands and the
head can occur when the driver airbag is deployed.
Ignition lock
Petrol engines
- ignition switched off, engine off
- ignition switched on
- start engine Diesel engines
- interruption of fuel supply, ignition switched off, engine off, the
steering can be locked.
- heating glow plugs on, ignition switched on
•You should not switch on any major electrical components during the
heating period otherwise the vehicle battery will be drained unnecessarily.
- start engine
Applies to all models:
Position
To lock the steering , with the ignition key withdrawn, turn the steering
wheel until the steering locking pin is heard to engage. You should always
lock the steering as a general rule if you leave your vehicle. This acts as
a deterrent against possible theft of your vehicle ⇒.
Position
Move the steering wheel back and forward a little if the ignition key cannot,
or cannot easily be turned into this position, in order to release the
steering lock.
Position
The engine is started in this position. At the same time switched on low
beam or main beam or other electrical components with major power
consumption are briefly switched off. The ignition key moves back into
position when one releases the key.
The ignition key must be turned back into position each time before
starting the engine again. The starter repeat lock in the ignition lock
prevents the starter being engaged when the engine is running and thus
getting damaged.
Ignition key withdrawal lock (automatic gearbox)
You can only withdraw the ignition key after switching off the ignition if the
selector lever is in position P.

WARNING
•When driving, the ignition key must always be in the position
(ignition switched on) without the en gine running. This position is
indicated by the warning lights coming on. If this is not the case, it
could result in unexpected locking of the steering wheel - risk of
accident!
•Do not withdraw the ignition key from the lock until the car has
come to a stop. The steering lock can engage immediately - risk of
accident!
•Always withdraw the ignition key if you are going to leave the
vehicle, even for a short time. This is particularly important if chil-
dren are left in the vehicle. The children might otherwise start the
engine or operate electrical equi pment (e.g. power windows) - risk
of injury!
Starting the engine
General
You can only start the engine only using an original ignition
key.
•Place the gearshift lever into neutral and put on the handbrake firmly
before starting the engine.
•The clutch pedal should be fully depressed when starting the engine
which means that the starter only has to crank the engine.
•Let go of the key as soon as the engine starts otherwise there may be
damage to the starter. The engine running noises may louder at first be louder for a short time
after starting the cold engine until oil pressure can be built up in the
hydraulic valve clearance compensation. This is quite normal and is not
an operating problem.
If the engine does not start ...
You can use the battery of another vehicle as a jump-start aid
⇒
page 243.
It is only possible to tow-start vehicles fitted with a manual gearbox. The
tow-starting distance must not be more than 50 metres ⇒page 247.
WARNING
•Never run the engine in non ventilated or enclosed areas. The
exhaust gases of the engine contain besides the odorless and
colourless carbon monoxide a poisonous gas - hazard! Carbon
monoxide can cause unconsciousness and death.
•Never leave your vehicle unattended with the engine running.
Caution
•The starter may only be operated (ignition key position ), if the
engine is not running. If the starter is immediately operated after switching
off the engine, the starter or the engine can be damaged.
•Avoid high engine revolutions, full throttle and high engine loads as
long as the engine has not yet reached its normal operating temperature
- risk of damaging the engine!
•Vehicles which are fitted with an exhaust gas catalytic converter
should not be tow-started over a distance of more than 50 metres.
