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 standi ng in a traffic jam.Switching recirculated air mode on– Press the button page 80, fig. 96 - the warning light lights up in the button.Switching recirculated air mode off– Press again the button - the warning light in the button goes out.
The button cannot be pressed if the control dial is in the position
or close
to this position.
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 occupants, divert your atten-
tion 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.Using the air conditioning system economicallyThe compressor on the air conditioning syst em uses power from the engine when in
cooling mode which will effect the fuel consumption.
It recommended to open the windows or the doors of a vehicle for which the interior
has been strongly heated through the effect of direct sunlight in order to allow the
heated air to escape.
The cooling system should not be switched on while travelling when the window is
open.
The desired interior temperature can also be achieved without switching in the cooling
system just by switching to fresh air mode.
For the sake of the environment
When you economize on fuel, you also reduce pollutant emissions.Climatronic* (automatic air conditioning)Description
The Climatronic system is a combinat ion of an automatic heating, fresh
air and cooling system which provides optimal comfort for the occu-
pants of the car.The Climatronic maintains a constant temp erature 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 distribution. The system also takes into account bright
sunlight which eliminates the need to alter the settings manually. The automatic
mode page 84 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 +5 °C,
the button is not pressed.
If the cooling system is switched on, th e temperature and air humidity drops in the
vehicle. The wellbeing of the occupants of the car is enhanced as a result of this partic-
ularly 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 recirculat ed 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.

Technical Data
The AC compressor is switched off at a hi
gh 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 condi-
tioning may drip down and form a puddle be low the vehicle. This is quite normal and
not an indication of a leak!
If you make a change before switching off the ignition, which differs from the auto-
matic mode, the changed functi ons remain stored. Only the function “circulating air”
is erased 20 minutes after switching off the ignition.
Recommended setting for all periods of the year:
Set the temperature to 22 °C (72 °F).
Press the button page 83, fig. 97.
Move the air outlet vents 3 and 4, so that the air flow is directed slightly upwards
page 77, fig. 94 .
Switching over between degrees Celsius and degrees Fahrenheit
Press and hold the buttons 17 and 9 page 83, fig. 97 . 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 mistin g. Please familiarize yourself about
how to correctly operate th e 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 recirculated 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 minut es at the highest blower stage - also during the cold season of the year - in order to avoid such odours. Also open a window
for a short time.
We recommend that you do not smoke in
the vehicle when the recirculating air
mode is operating since the smoke which is drawn at the evaporator from the interior
of the vehicle forms deposits in the evapor ator 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 compart-
ment.

temperature below +18°C (64°F), “LO” appears in the display. If you select the temper-
ature higher than +29°C (84 °F ), “HI” appears in the display. In both limit positions the
Climatronic operates at ma ximum 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 particular 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 six blower stages available.The Climatronic system controls the blower st ages automatically in line with the inte-
rior temperature. You can also, however, adap t the blower stages manually to suit your
particular needs.
– Press the button or page 83, fig. 97 in order to decrease or increase the
speed.
Switch off the blowers, the Climatronic is switched off and in the display shows OFF.
The set blower speed is indicated by the ligh ting up of the respective number of bars
at the point .
WARNING
“Stale air” may result in fatigue in the driver and occupants, reduce atten-
tion levels and also cause the windows to mist up. The risk of having an accident
increases.
Do not switch the Climatronic system off for longer than necessary.
Switch the Climatronic system on as soon as the windows mist up.

Operational problemsIf all the symbols on the display of the au tomatic air conditioning system flash for
approx. 15 seconds after switching on the igniti on, then there is a fault in the system -
visit a specialist garage.
If the cooling system does not oper ate, the following faults may exist:
the outside temperature is lower than +5°C,
The compressor of the automatic air conditioning system was temporarily
switched off due to a too high temperature of the coolant,
a blown fuse.
Check the fuse, replace it if necessary page 177. If a blown fuse is not the source of
the fault, switch the Climatronic off and have it checked.
If the cooling capacity decreases, switch the Climatronic off and have it checked.

Passive Safety
98
Ensure that no objects can obstruct the pedal.
Adjust the mirror, the front seat and the head restraint to match your body size.
Point out to your occupants that the head restraints must be adjusted to match
their body size.
Protect the children in suitable child seats with correctly fastened seat belts
page 115, “Transporting children safely”.
Adopt the correct seated position page 98, “Correct seated position”. Also
inform your occupants to adopt the correct seated position.
Fasten the seat belt correctly. Also inform your occupants to properly fasten the
seat belts page 104, “How are seat belts correctly fastened?”.
What influences the driving safety?
The driving safety is primarily determined by the style of driving and the
personal behaviour of all the occupants.The driver is fully responsible for himself an d his occupants. If your driving safety is
effected, you place yourself and the oncomi ng traffic at risk. Please refer to the
following guidelines.
Do not get distracted from concentrating on the traffic situation, e.g. by your occu-
pants or mobile phone calls.
Never drive when your driving ability is impaired, e.g. through medication, alcohol,
drugs.
Keep to the traffic regulations and the permissible speed limit.
Adjust the driving speed at all times to the road condition as well as to the traffic
and weather conditions.
Take regular breaks on long journe ys - at the latest every two hours.
Correct seated positionCorrect seated position for the driver
Correct seated position for the driver is important for safe and relaxed
driving.For your own safety and to reduce the risk of injury in the event of an accident, we
recommend the following setting:
Adjust the steering wheel so that the distance between the steering wheel and your
chest is at least 25 cm fig. 106 .
Position the driver seat in the forward/back direction so that you are able to fully
press the pedals with your legs at a slight angle.

Seat belts
104
The belt webbing must not run across solid or fragile objects (e.g. specta-
cles, ball-point pens, keys etc.) as this may be a cause of injuries.
Bulky, loose clothing (e.g. a winter coat over a jacket) does not allow you to
be correctly seated and impairs pr oper operation of the seat belts.
It is prohibited to use clamps or other objects to adjust seat belts (e.g. for
shortening the belts for smaller persons).
The lock tongue should only be inserted into the lock which is the correct
one for your seat. Wrong use of the safety belt will reduce its capacity to protect
and the risk of injury increases.
The seat backrests of the front seats must not be tilted too far to the rear
otherwise the seatbelts can lose their effectiveness.
The belt webbing must al ways be kept clean. Soiled belt webbing may
impair proper operation of the inertia reel page 143, “Seat belts”.
The slot of the belt tongue must not be blocked by paper or similar objects
otherwise the belt tongue will not lock in place properly.
Inspect the seat belts regularly to ensure they are in good condition. If you
find seat belts which have damage to th e seat belt webbing, seat belt connec-
tions, to the inertia reels or to the lock, the relevant safety belt must be replaced
by a specialist garage.
The seat belts must not be removed or changed in any way. Do not make an
attempt to repair the seat belts yourself.
Damaged seat belts which have been subjected to stress in an accident and
were therefore stretched, must be replaced - this is best done by a specialist
garage. The anchorage points of the belts must also be inspected. The
anchorage points for the belts should also be checked.
In certain countries it is possible to use seat belts which differ in terms of
their operation from the seat belts wh ich are described on the pages which
follow.
How are seat belts correctly fastened?Fastening three-point seat belts
Fasten your seat be lt before starting!– Correctly adjust the front seat and the he ad restraint before fastening your seat
