Heating and air conditioning
Heating and air conditioning General notes
The power of the heating depends on the temperature of the coolant. There-
fore, maximum power is only obtained when the engine has reached operat-
ing temperature.
The temperature and the humidity of the air is reduced when the system
cools the interior of the vehicle. This therefore increases the comfort of all
vehicle occupants when outside temperatures and humidity are high. It also
helps prevent the windows from misting over during cold periods of the
year.
The air recirculation system can be switched on temporarily to increase the
cooling effect.
Keep the air intake slots in front of the windscreen clear of ice, snow or
leaves to ensure unimpaired heating and cooling.
When the air conditioning is on, condensation can drip from the evaporator
in the air cooling system and form a pool underneath the vehicle. This is
normal and does not indicate a leak!
WARNING
● All windows must be clear of ice, snow and condensation for driving
safety. Therefore, make sure you familiarise yourself with the correct use
of heating and ventilation, window demisting and defrosting and cooling.
● Never use the air recirculation system for too long, as it prevents
fresh air from entering the vehicle and “used” air can cause tiredness, re-
duce your attention span and cause the windows to mist over. This in-
creases the risk of an accident. Switch off the air recirculation system as
soon as the windows begin to mist over.
Note
● Used air escapes through ventilation slots in the rear of the luggage
compartment.
● Smoking is not recommended while the air recirculation system is in
use, as the smoke drawn from the interior of the vehicle settles in the evap-
orator of the air conditioning system. This causes a persistent, unpleasant
smell while the system is running that is time-consuming and expensive
(evaporator replacement) to eliminate.
● Never cover the air outlets to ensure the system operates correctly. 
Economic use of the air conditioning system
When the air conditioning is switched on, the compressor consumes engine
power and has an impact on fuel consumption.
If the vehicle interior has heated up after standing in the sun for some time,
the air inside can be cooled by opening the windows or doors to allow the
hot air to escape. 

126Heating and air conditioning
While in motion, the air conditioning should not be switched on if the win-
dows are open.
If the interior temperature can be reached without switching on the air con-
ditioning, the fresh air mode should be used.
For the sake of the environment
This saves on fuel and reduces emissions. 
Faults
If the air conditioning does not work at outside temperatures above +5 °C
(+41 °F) then the system is faulty. This may be due to one of the following
reasons:
● One of the fuses has blown. Check the fuse and replace if necessary
⇒  page 210.
● The air conditioning compressor has switched off temporarily because
of an increased engine coolant temperature ⇒ page 56.
If you cannot repair the fault yourself or where the cooling power continues
to drop, switch the system off. Contact a specialised service. Air ventsFig. 97 Air vents
Opening air vents 3 and 4
– Turn the vertical circular control upwards.
Closing air vents 3 and 4

Changing the direction of air delivery from air vents 3 and 4
– The air circulation height can be varied by changing the posi-
tion of the sliding adjuster upwards or downwards ⇒ Fig. 97.
– The air circulation direction can be varied by changing the posi-
tion of the sliding adjuster to the right or to the left.
The flow of air from the vents is controlled using control C
⇒ Fig. 98. Vents
3 ⇒ Fig. 97 and 4 can be opened and closed individually.
Depending on the position of the adjusters and on the weather, open vents
can provide air which is either heated, unheated or cooled. 

Air conditioning (manual)* General notes
The air cooling system only works if the AC button
2 ⇒ Fig. 99
⇒ page 129 is pressed and under following conditions:
● The engine is running
● The outside temperature is above +2 °C (+36 °F)
● The blower control is in position 1 – 4
When the cooling system is on and under certain conditions, air can be
blown from the vents at a temperature of approx. 5 °C (41 °F). In the event
of prolonged, irregular distribution of the air flow from the outlets and sig-
nificant differences in temperature, e.g. on leaving the vehicle, sensitive
people may catch a cold.
Note
A visit to the specialised service once a year is recommended to clean the
air conditioning system. Operation

Climatronic* (automatic air conditioning) General notes
Climatronic automatically maintains a comfortable temperature. To do so, it
automatically regulates the supplied air temperature and the blower and air
distribution levels. The system also allows for the effect of sunlight, so there
is no need for manual adjustment. Automatic operations ⇒ page 133 guar-
antee maximum comfort any time of year.
Climatronic description
Cooling only works if the following conditions are met:
● The engine is running
● The outside temperature is above +2 °C (+36 °F)
● AC
18 ⇒ Fig. 100 ⇒ page 133 on. In order to ensure engines subject to heavy loads are cooled, the air condi-
tioning compressor is switched off in the event of high coolant tempera-
tures.
Recommended setting for all seasons
●
Set the required temperature. We recommend 22 °C (72 °F).
● Press the AUTO
button 12 ⇒ 
Fig. 100 ⇒  page 133.
● Adjust vents 3 ⇒ page 126 and 4 so that the air flow is directed slightly
upwards.
Change between degrees Centigrade and degrees Fahrenheit
Keep the AUTO
and AC buttons
⇒ Fig. 100 ⇒  page 133 pressed down at

Note
A visit to the specialised service once a year is recommended to clean the

Automatic mode
Automatic mode is used to maintain a constant temperature and
demist the windows inside the vehicle.
Switching on automatic mode
– Set the temperature to between +18 °C (+64 °F) and +29 °C
(+84 °F).
– Adjust vents 3 ⇒ page 126 and 4 so that the air flow is directed
slightly upwards.

134Heating and air conditioning
Temperature selection
–When you switch on the ignition, control 1 ⇒ Fig. 100
⇒ page 133 can be used to set the required interior tempera-
ture.
The interior temperature can be set to between +18 °C (+64 °F) and +29 °C
(+84 °F). The temperature is regulated automatically within this range. If a
temperature below +18 °C (+64 °F) is selected, “LO” is displayed on the
screen. If a temperature above +29 °C (+84 °F) is selected, “HI” is displayed
on the screen. At both extremes, Climatronic works at maximum cooling or
heating power, respectively. The temperature is not regulated.
In the event of prolonged, irregular distribution of the air flow from the out-
lets (particularly the footwells) and significant differences in temperature,
e.g. on leaving the vehicle, sensitive people may catch a cold. 
Air recirculation
Air recirculation prevents unpleasant smells, e.g. when passing
through a tunnel or in queuing traffic, from entering the interior.
Switching on air recirculation mode
– Press button 
17 ⇒ Fig. 100 ⇒ page 133 and the
 sym-
bol is displayed on the screen.
Switching off air recirculation mode
– Press button 
17 ⇒ Fig. 100 ⇒ page 133 and the
 sym-
bol disappears from the screen.
WARNING
Never use the air recirculation system for too long, as it prevents fresh air
from entering the vehicle and “used” air can cause tiredness, reduce your
attention span and cause the windows to mist over. This increases the
risk of an accident. Switch off the air recirculation system as soon as the
windows begin to mist over.
Note
If air recirculation mode remains on for 15 minutes, the  symbol will
start to flash on the screen to indicate prolonged air recirculation. If air recir-
culation is not switched off, the symbol will continue to flash for 5 minutes. 
Blower selection
Climatronic automatically regulates the blower speed according to
the interior temperature. It is possible, however, to set the blower
speed to suit requirements.
– Turn rotary control 10
⇒ Fig. 100 ⇒ 
page 133 anti-clockwise
(decrease speed) or clockwise (increase speed).
Climatronic will switch off when the blower switches off.
WARNING
● “Used air” can cause tiredness, reduce attention spans and cause the
windows to mist over. This increases the risk of an accident.
● Do not switch off Climatronic for longer than necessary.
● Switch Climatronic back on as soon as the windows begin to mist
over.
