Heating, Ventilation and Air conditioning152

When the button is off (LED off), the heating, ventilation and air condi-

tioning system is off.

When the button is off, the heating, ventilation and air conditioning

system is switched off to save fuel. The temperature continues to self-regu-

late. The set temperature can then only be reached if it is higher than the

ambient temperature.

Driver and passenger temperature control

The button controls the synchronisation of the 2 Climatronic climate

zones.

When the button is on (LED lit), the climate zone of the Climatronic is

personalised, for example: Driver side temperature 22°C and passenger side

temperature 23°C.

When the button is off (LED off), the climate zone of the Climatronic is

synchronised, for example: Driver side temperature 22°C and passenger side

temperature 22°C.

If the button is off and the passenger side temperature is changed, the

function is automatically activated.

Air recirculation mode

Air recirculation mode prevents fumes or unpleasant smells

from coming from the outside.

– Press the button ⇒ page 151, fig. 114 to switch air recir-

culation mode on or off. It is switched on if the following symbol

appears in the display

.

Air recirculation mode prevents strong odours in the ambient air from

entering the vehicle interior, for example when passing through a tunnel or in

a traffic jam.

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.

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 selected, the recirculation mode is deacti-

vated. For safety reasons, the air recirculation mode should not be

connected.

WARNING

In air recirculation mode, no cold air 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).

General notes

The impurity filter

The impurity filter (a combined particle filter and active carbon filter) serves

as a barrier against impurities in the ambient air, including dust and pollen.

For the air conditioning system to work with maximum efficiency, the pollen

filter must be replaced at the intervals specified in the Service Schedule.

If the filter loses efficiency prematurely due to use in areas reaching very high

pollution levels, the pollen filter must be changed more frequently than

stated in the Service Schedule.

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 is not running.

• The button is disconnected.

• 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.

Caution

• If you suspect that the air conditioning is damaged, switch it off with the

button to prevent further damage and have it checked by a qualified

workshop.

• Repairs to the air conditioning system require specialist knowledge and

special tools. Therefore, we recommend you to take the vehicle to a qualified

workshop.

Note

• If the humidity and temperature outside the vehicle are high, condensa-

tion can drip off the evaporator in the cooling system and so forming a puddle

underneath the vehicle. This is completely normal and there is no need to

suspect a leak.

• Keep the air intake slots in front of the windscreen free of snow, ice and

leaves to ensure heating and cooling are not impaired, and to prevent the

windows from misting over.

• The air from the vents flows through the passenger compartment and is

extracted by slots designed for this purpose. 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 been over-

heated by sun, the air inside can be cooled quicklier by opening the windows

for a short time.

• Do not smoke while air recirculation mode is on, as smoke drawn into the

air conditioning system leaves a residue on the evaporator, producing a

permanent unpleasant odour.

• It is advisable to connect the air conditioning at least once a month, to

lubricate the system gaskets and prevent leaks. If a decrease in the cooling

capacity is detected, an Authorised Service Centre should be consulted to

check the system.
