Air conditioning
Defrosting
The windscreen and side windows are defrosted or demisted
as quickly as possible.
– To enable this mode, press the
⇒
Fig. 128 button.
– To switch off, press the
button again, or select the AUTO but-
ton.
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 162.
The air recirculation and ECON modes are switched off when the
button
is pressed.
Air recirculation: manual activation
The air recirculation setting prevents fumes etc. from enter-
ing the interior.
Activating air recirculation mode
– Press button
⇒ Fig. 128 ⇒ .
Deactivating air recirculation mode
– Press the
button again or
– Press the AUTO
button or
– Press button
.
In this setting, the air in the vehicle is constantly recirculated. We recom-
mend using the air recirculation mode in the following circumstances: ●
When driving through a tunnel or in traffic congestions, to prevent ex-
haust gas 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
ECON mode helps save fuel.
– To activate, press the ECON
button ⇒ Fig. 128.
– To deactivate, press the ECON
button again or select the AUTObutton.
Air cooling is disconnected in ECON mode. The heating and the blower are
adjusted automatically. “ECON” stands for “Economy”. Disconnecting air
cooling (compressor) reduces fuel consumption.
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.
In diesel vehicles, the auxiliary heater is switched off in ECON mode to save
fuel.
Safety FirstOperating InstructionsPractical TipsTechnical Specifications
164Air conditioning
If the air recirculation mode is on when you switch off the engine, the air
conditioner will automatically switch to fresh air ventilation.
Auxiliary heater*
Diesel vehicles are fitted with an auxiliary heater 1)
to raise the temperature
of the interior as quickly as possible. At outdoor temperatures below +5 °C
and with the engine running, the supplementary heating will switch on and
off automatically depending on the temperature of the coolant.
In order to save fuel, the auxiliary heater can be can be switched off by brief-
ly pressing the
button on the air conditioner. Seat heating*
The surface and backrest of the front seats can be electrical-
ly heated.
Fig. 131 Detailed view of
the dash panel: Thumb-
wheel controls for seat
heating
Turn thumbwheel 1
or 2 ⇒ Fig. 131 to switch on and adjust the
heating on the left or right front seats.
The heating is switched off when the thumbwheel is set to 0. The tempera-
ture settings range from 1 to 6.
CAUTION
To avoid damaging the heating elements of the seat heating, please do not
kneel on the seat or apply sharp pressure to a single point.

Checking and refilling levels
Coolant fluid loss
Any loss of coolant fluid normally indicates a leak in the cooling system. In
this case the cooling system should be inspected by a specialised work-
shop without delay. It is not sufficient merely to top up the coolant fluid.
If there are no leaks in the system, a loss of coolant fluid can only occur if
the coolant boils and is forced out of the system as a result of overheating.
CAUTION
Radiator sealants must not be added to the coolant fluid. Such additives
could seriously impair the function of the cooling system.
Topping up the coolant fluid
Be careful when topping up with coolant fluid. – Switch the engine off.
– Wait for the engine to cool down.
– Cover the cap on the expansion tank ⇒ Fig. 171 with a cloth,
and carefully unscrew the cap anticlockwise ⇒
.
– Add coolant fluid.
– Screw on the cap tightly.
Make sure that the coolant fluid meets the required specifications
⇒ page 231. Do not use a different type of antifreeze if G12++ antifreeze is
not available. In this case, use only water and bring the antifreeze concen-
tration back up to the correct level as soon as possible.
Always top up with new coolant fluid. Do not fill above the “max” mark. Excess coolant fluid is forced out of the
system through the valve in the filler cap when the engine gets hot.
If a lot of coolant fluid has been lost, wait for the engine to
cool down before
putting in cold coolant. Failure to do so could result in serious engine dam-
age.
WARNING
● The cooling system is under pressure. Do not unscrew the cap on the
expansion tank when the engine is hot. Failure to comply could result in
burns.
● The antifreeze and coolant fluid can be a health hazard. Therefore,
the antifreeze should be stored in the original container in a safe place
out of reach of children. Failure to comply could result in poisoning.
For the sake of the environment
Drained off coolant should not be used again. Drain off the used coolant in-
to a suitable container and dispose of it in the proper manner (observe envi-
ronmental regulations).
Radiator fan
The radiator fan can start running spontaneously. The auxiliary fan can continue to run for as long as 10 minutes after stop-
ping the engine, even after the ignition is switched off. It may also start run-
ning suddenly ⇒
after some while if
● Stored heat raises the coolant temperature, or
● The hot engine compartment is additionally heated up by the sun.
