or frequency of the selected radio station and various other information,
depending on the type of radio fitted.
When in CD mode*, the display will show the current track.
If you have a compatible telephone*, the phone book or telephone dialled
can also be seen on this display.
These displays appear in addition to the display on the radio itself.
Ambient temperature displayThe ambient temperature is shown in the display when the ignition is
switched on ⇒fig. 49 . On vehicles with an automatic gearbox, the display
does not appear until the driver has engaged a gear.
At temperatures below +5°C a snowflak e symbol appears next to the temper-
ature display. This is to warn the driver to take extra care when there is a risk
of ice on the road. When the vehicle is stationary or travelling at very low
speeds, the temperature displayed may be slightly higher than the actual
ambient temperature as a result of heat coming from the engine.
If the vehicle has an air conditioning and the display is changed over to °F
(degrees Fahrenheit), the ambient temperature display automatically
changes over to °F ⇒page 165.
WARNING
Do not rely on the ambient temperature display as an ice warning. Please
bear in mind that there may be ice on the roads even at ambient tempera-
tures of +5°C – beware of ice patches.

Heating, Ventilation and Air conditioning
160Heating, Ventilation and Air conditioning2C-ClimatronicDescription
The climate control is designed to automatically keep the
passenger compartment at the temperature you find most
comfortable at all times of the year.Recommended settings:
– Set the temperature to 22°C (71°F).
–Press the ⇒page 162, fig. 141 button.The following setting quickly provides a comfortable temperature inside the
vehicle. We therefore recommend you do not modify the setting unless you
find this temperature uncomfortable or where circumstances require as such.
The climate control provides heating and ventilation and also cools and
dehumidifies the air inside the vehicle.
The climate control is fully automatic and will constantly maintain the temper-
ature which has been set. To achieve this, the temperature of the air supplied
to the interior, the blower speed (volume of air delivery) and the air distribu-
tion are regulated automatically. The system also takes solar radiation into
account and, therefore, no subsequent manual readjustments are required.
Therefore, automatic mode ⇒ page 163 should be used for the comfort of all
the passengers in virtually all conditions throughout the year.
Please note the following points:
The humidity of the air is automatically reduced when the system cools the
interior of the vehicle. This helps to prevent condensation on the windows. If the humidity and temperature outside the vehicle are high,
condensation
can drip off the evaporator in the air cooling system and form a pool under-
neath the vehicle. This is normal and does not indicate a leak.
If the outside temperature is low, the blower normally only switches to a
higher speed once the coolant has warmed up sufficiently (this does not
apply to the defrost setting).
In order to achieve maximum engine power, the air conditioning compressor
is tem po ra r ily s witche d o ff whe n pulli ng away f ro m s tan dstill wit h full th rot tle.
The compressor also switches off if the coolant temperature is excessively
high to ensure adequate engine cooling under extreme loads.
Pollution filter
The pollution filter (a combined particle filter and activated charcoal filter)
serves as a barrier against impurities in the outside air, including dust and
pollen.
For the climate control to work with maximum efficiency, the pollution filter
element must be replaced at the intervals specified in the Service Schedule.
If the vehicle is driven in areas with a high level of air pollution and the filter
is no longer fully effective, it may be necessary to change the filter element
more frequently.
Caution
•If you suspect that the climate control system is damaged, switch over to
ECON mode to prevent further damage and have the system checked by a
specialist garage.•Repairs to the climate control require specialist knowledge and special
tools. For this reason, please contact a specialist garage if the system is not
working properly.

Note
•Keep the air intake slots in front of the windscreen clear of snow, ice and
leaves to ensure unimpaired heating and cooling and to prevent the windows
misting over.•The air from the outlets flows through the passenger compartment and
out through the slots below the rear window. Therefore, do not cover these
slots with items of clothing or other objects.•The air conditioning system operates most effectively with the windows
and the sliding/tilting roof* closed. However, if the vehicle has heated up
after standing in the sun for some time, the air inside can be cooled more
quickly by opening the windows briefly.

162Controls
This overview will help you become quickly familiar with the controls for the climate control.The left-hand display shows the temperature selected for the left-hand side
and the right-hand display the temperature for the right-hand side.
The functions can be switched on or off by briefly pressing the buttons. The
diode on the buttons lights up when the function is enabled.
The grille between buttons and must be kept clear, as the tempera-
ture sensors are located behind the grille.•Do not cover the grille.•Do not clean the grille with a vacuum cleaner, as this could damage the
temperature sensors located behind the grille.

The , and buttons (which regulate air distribution) can either be
selected individually or in combination.
Automatic mode
Standard setting for all seasons.Switching on automatic mode
– Select a temperature between +18°C (64°F) and +29°C (86°F).
– Press the button
⇒page 162, fig. 141 .The automatic mode maintains a constant temperature inside the vehicle and
dehumidifies the air. Air temperature, air delivery and air distribution are
regulated automatically to reach the desired interior temperature as quickly
as possible, and then to maintain this temperature. The system automatically
compensates for any variations in the outside temperature and for the effect
of direct sunlight.
The automatic temperature regulation only operates at temperature settings
between +18°C and +29°C. If a temperature below +18°C is selected, LO
appears on the display. If a temperature is selected which is higher than
+29°C, the display will show HI. In the two extreme settings, the climate
control operates continuously with maximum cooling or heating output and the temperature is not regulated automatically. The temperature is not regu-
lated.
Note
By keeping the button on the driver's side pressed for several seconds,
the temperature of the passenger's side can be set to the temperature of the
driver's side or vice versa. The display indicates the new temperature value.Selecting the temperature
Separate temperatures can be selected for the driver's and
front passenger's side.– Press the or buttons below the displays
⇒page 162,
fig. 141 until the desired temperature is selected for the driver's
side or front passenger's side.The currently selected temperature setting is shown in the display above the

The windscreen and side windows are defrosted or demisted
as quickly as possible.– To enable this mode, press the ⇒page 162, fig. 141 button.
– To disable, press the button again or select the button.The temperature is regulated automatically. The air output is increased to
maximum and most of the air comes out of outlets 1 and 2 ⇒page 167.
The air recirculation and ECON modes are switched off when the button is
pressed.Air recirculation: manual enabling
The air recirculation setting prevents fumes etc. from entering
the interior.Enabling air recirculation mode
–Press the ⇒page 162, fig. 141 ⇒ button.
Disabling air recirculation mode
– Press the button again or
– Press the button or
–Press the button.In this setting, the air in the vehicle is constantly recirculated. We recommend
using the air recirculation mode in the following circumstances:
•When driving through a tunnel or in queues of traffic, to prevent fumes
entering the interior of the vehicle.WARNING
Do not drive for too long with the air recirculation mode enabled because,
if the compressor is disconnected, the windscreen may mist up because no
fresh air is entering the interior of the vehicle, with the subsequent risk of
accidents.ECON Mode (economy)
ECON mode helps save fuel.– To enable, press the button ⇒page 162, fig. 141.
– To disable, press the button again or select the button.Air cooling is disconnected in ECON mode. The heating and the blower are
adjusted automatically. “ECON” stands for “Economy”. Disconnecting air
cooling (compressor) saves on fuel.
Please note that the interior temperature must not be lower than the outside
temperature in ECON mode. The blower does not cool or dehumidify the air in
the interior. The windows could therefore mist up.
On diesel vehicles, the supplementary heater is switched off in ECON mode
to save fuel.
Note
If the diode on the ECON button continues to light up when the ECON mode
has been switched off (i.e. the climate control has been switched on) this is
