Climate control

Electronic climate control, ECC (option)

3. Recirculation

Recirculation can be used to

shut out bad air, exhaust

fumes, etc. from the

passenger compartment.

The air in the passenger

compartment is recirculated.

No outside air is taken into the car when this

function is activated. If the air in the car recir-

culates for too long, there is a risk of misting

on the insides of the windows.

Timer

The timer function minimises the risk of icing,

misting and bad air if recirculation is selected.

See page 64, for how to activate and

deactivate the function.

NOTE! When Defroster (4) is selected, recir-

culation is always deactivated.

3. Air quality system (option)

(same button as recircu-

lation)

The air quality system

consists of a multi-filter and

a sensor. The filter

separates gases and

particles to reduce the levels of odours and

pollution in the passenger compartment.

When the sensor detects polluted outside

air, the air intakes are closed and the air in the

passenger compartment is recirculated.

A green LED (A) lights in the button when the

air quality sensor is active.

Activating the air quality sensor

• Press the AUTO button (1) to activate the

air quality sensor (normal setting).

Or:

Switch between three functions by pressing

repeatedly the recirculation button.

• Air quality sensor engaged – LED (A)

lights.

• No recirculation engaged, provided it is

not required for cooling in hot weather –

LED not lit.

• Recirculation engaged – LED (M) lights.

Keep in mind the following:

• As a rule, the air quality sensor should

always be engaged.

• Recirculation is limited in cold weather to

avoid misting.

• If the insides of the windows start misting

up, disengage the air quality sensor.

• The defroster function for the front, side

and rear windows can also be used to

demist the windows.

4. Defroster

Quickly removes misting

and ice from the windscreen

and side windows. Air flows

to the windows at high fan

speed. The LED in the

defroster button lights when

the function is active.

When the function is selected the following

also takes place to provide maximum

dehumidification of the air in the passenger

compartment:

• the air conditioning (AC) is automatically

engaged

• recirculation is automatically disengaged.

When the defroster is switched off the

climate control returns to the previous

settings.

5. Air distribution

The airflow can be

distributed to the windows,

dashboard vents or floor by

pressing the air distribution

buttons.

A symbol on the display

above the climate control panel and a lit LED

in the button indicate which function has

been selected.

See the table on page 75.
