Te c h n i c a l D a t a
With low temperatures outside, the air recirculation increases the effective-
ness of the heating system by heating the air inside the passenger compart-
ment rather than the air from outside.
Air distribution
Control for setting the flow of air in the required direction.
 – Air distribution towards the windscreen. If the windscreen air output is
on and the air recirculation mode is pressed, this remains active. When the
recirculation mode is on, if the air di stribution towards the windscreen mode
is selected, the recirculation mode is deactivated. For safety reasons, the air
recirculation mode should not be connected. – Air distribution to the upper body. – Air distribution to footwell – Air distribution to the windscreen and the foot well.
Blower
The air flow can be set at four speeds with the control . The air flow should
always be set at the lowest speed when driving slowly.
WARNING
•
For road safety all windows must be clear of ice, snow, and condensa-
tion. This is essential to ensure good visibility. Please familiarise yourself
with the correct operation of the heat ing and ventilation system, including
the anti-fog/defrost functions for the windscreens.
•
In air recirculation mode, no cold ai r from the outside enters the vehicle
interior. The windows can quickly fog over if the heating is switched off.
Therefore, never leave the air recircul ation mode switched on for a long
time (risk of accident).Note
Please observe the general notes ⇒page 152.

– Use the air distribution control to guide the flow of air in the required direction: (to the windscreen), (to the upper
body), (to the foot well) and (to the windscreen and to the
foot well).Heating
Maximum heat output, which is needed to defrost the windows quickly, is
only available when the engine has reached its operating temperature.
Air conditioner
When the air conditioning system is switched on, not only the temperature,
but also the air humidity in the vehicle interior is reduced. This improves comfort for the vehicle occupants and prevents misting of the windows when
the ambient air humidity is high.
If the air conditioning system cannot be switched on this may be caused by
the following reasons:
•
The engine may not be running.
•
The blower is switched off.
•
The outside temperature is below +3°C.
•
The air conditioning system compressor has been temporarily switched
off because the engine coolant temperature is too high.
•
The air conditioning fuse is faulty.
•
Another fault in the vehicle. Have the air conditioning checked by a qual-
ified workshop.
Air recirculation mode
Air recirculation mode prevents fumes or unpl easant smells from coming from the outside.

Air recirculation mode
⇒page 146, fig. 110 prevents strong odours in
the outside air from entering the vehicle interior, for example when passing
through a tunnel or in queuing traffic.
With low temperatures outside, the air recirculation increases the effective-
ness of the heating system by warming the air inside the passenger compart-
ment rather than the cold air from outside.
With high ambient temperatures, the air recirculation increases the effective-
ness of the air conditioning system by cooling the air inside the passenger
compartment rather than the ambient air.
If the windscreen air output is on and the air recirculation mode is pressed,
this remains active. When the recirculation mode is on, if the air distribution
towards the windscreen mode is select ed, the recirculation mode is deacti-
vated. For safety reasons, the air recirculation mode should not be
connected.
WARNING
In air recirculation mode, no cold ai r from the outside enters the vehicle
interior. If the air conditioning system is switched off, the windows can
quickly mist over. Therefore, never leave the air recirculation mode
switched on for a long time (risk of accident).

The controls allow separate adjustment of air conditioning settings for the left and right.The air conditioning system controls the temperature when the
engine is running and the blower is switched on.
– Turn the temperature control knobs ⇒ fig. 111 or in order
to adjust the temperature on the left hand side or the right hand
side respectively.
– The functions will be switched on when its buttons are pressed. When these functions are activated, they are indicated on the
radio display. In addition, all these functions are lit with LEDs.
Press the button again to switch off the function.
The temperature can be adjusted separately for the left and right sides of the
vehicle interior.
Button – defrost function for the windscreen. The air drawn in from
outside the vehicle is directed at the windscreen. The air recirculation
mode, if switched on, will be switched off as soon as the defrost function
is switched on. At temperatures over 3°C, the air conditioning system will
be switched on automatically and the blower speed will be increased by
one level in order to dry the air. The button is lit in yellow and the symbol
appears on the radio or navigator display.

150The LEDs on the Climatronic controls indicate that the selected function has
been activated.
In addition, the radio or radio and na vigation displays mounted at factory
briefly display the current settings of the Climatronic if any are modified.
The symbols used on the radio or radio and navigation displays are the same
as the symbols used for the Climatronic controls.Automatic mode
In automatic mode air temperatur e, air flow and distribution
are automatically regulated so th at a specified temperature is
attained as quickly as possible and then maintained.The temperature can be adjusted separately for the left and right
sides of the vehicle interior.
Switching on automatic mode
– Press the ⇒page 148, fig. 111 button. “AUTO High” is
shown on the radio display (high fan speed).
– Press the button again ⇒page 148, fig. 111 . “AUTO Low”
is shown on the radio display (low fan speed).Depending upon the version and finish, the vehicle may include:
When a temperature of 22°C (72°F) is set in automatic mode a comfortable
interior climate is quickly reached. Therefore, we recommend you not to
change this adjustment, except as necess ary to suit individual preferences or
particular circumstances. The compartment temperature can be set between
+18°C (64°F) and +26°C (80°F). These are approximate temperatures and the actual temperature may be slightly high
er or lower depending on the ambient
conditions.
Climatronic maintains a constant temperature. The temperature of the air
supplied to the interior, the blower speed and the air distribution are regu-
lated automatically. The system also considers the sunlight radiation, so
there is no need for manual readjustment. Therefore, automatic mode almost
always provides the best comfort for the vehicle occupants throughout the
year.
Automatic mode is switched off whenever an adjustment is made using the
buttons for the air distribu tion, air flow or or the air recirculation button
. The temperature will continue to be regulated within the parameters
manually selected by the user.
Note
There are two automatic modes:•
Automatic mode LO: This calculates the air flow for two people.
•
Automatic mode HI: This calculates the air flow for more than two
people.

Manual mode
In manual mode you can adjust the air temperat ure, air flow and distribution as required.Switching on manual mode
– To enter manual mode, press one of the buttons ⇒fig. 114 to
or press the air flow control . The selected function is
shown on the radio or navigator display.Temperature
There are separate temperature selectors for the left and right sides of the
vehicle interior. The selected temperature is displayed above the selector.
The compartment temperature can be set between +18°C (64°F) and +26°C
(80°F). These are approximate temperat ures and the actual temperature may
be slightly higher or lower depending on the ambient conditions.
If a temperature below 18°C (64°F) is selected, the display switches to LO In
this setting the system runs at maximum cooling output and the temperature
is not regulated. If a temperature above 26°C (80°F) is selected, the display switches to
HI In
this setting the system runs at maximum heating output and the temperature
is not regulated.
Blower
The air flow may be adjusted freely using the control . Always have the
blower running at a low setting to ensure a constant flow of fresh air into the
vehicle. Pushing the button
 to the minimum -1, turns the Climatronic off.
Air distribution
The air distribution is adjusted using the buttons , and . It is also
possible to open and close some of the air vents separately.
Switching the air conditioning system on and off
When the button is on (LED lit), the heating, ventilation and air condi-
tioning system is on.
