2. Blower speed
The blower speed can be
increased or decreased by
turning the knob. The blower
speed is regulated automati-
cally if AUTO is selected. The
previously set blower speed is
disconnected.
NOTE
If the knob is turned counterclockwise and
the blower indication in the display goes
out, the blower and the air conditioning are
switched off. The display shows the blower
OFF
symbol and .
3. Recirculation
This function is used to recir-
culate the air in the passenger
compartment, which means
that when the function is
active, no outside air enters
the compartment. This is par-
ticularly useful in hot or cold
weather to cool or heat the passenger com-
partment faster, or to help shut out exhaust
fumes, etc.
Press the button repeatedly to close out out-
side air (recirculation) or to let outside air flow
into the passenger compartment.
•
If the green indicator light to the left is on,
recirculation is on and no outside air flows
into the passenger compartment.
•
If the green indicator light to the right is on,
outside air flows into the passenger com-
partment.
While the indicator light on the right side is on,
the ECC system automatically controls the flow
of air into the passenger compartment and the
air intake is opened or closed depending on the
outside temperature, the need to heat or cool
the compartment, etc.
If the air in the car recirculates for too long,
there is a risk of condensation forming on the
insides of the windows, especially in winter.
Recirculation timer
The timer function minimizes the risk of fogging
or stale air when the recirculation function is
selected, see page 83 for information on set-
ting the recirculation timer.
NOTE
If the defroster function is switched on (by
pressing button 4), recirculation is always
disengaged.
I n f o r m a t i o n P r o v i d e d b y :
Electronic Climate Control (ECC)*
Interior Air Quality System (IAQS)*
This system consists of a mul-
tifilter that helps reduce gases
and particles in the incoming
air and an air quality sensor
that detects increased levels
of contaminants in the outside
air. When the air quality sen-
sor detects contaminated outside air, the air
intake closes and the air inside the passenger
compartment is recirculated. The filter also
cleans recirculated passenger compartment
air.
When IAQS is engaged, the green indicator
light above A is illuminated.
To activate IAQS:
±
Press AUTO (1).
Or:
Toggle between the system's three modes by
pressing the button the recirculation button
repeatedly.
•
The green indicator light above A is on:
IAQS is engaged. Outside air flows into the
passenger compartment and is filtered.
While this light is on, the ECC system auto-
matically controls the flow of air into the
passenger compartment and the air intake
is opened or closed depending on the out-
side temperature, the need to heat or cool
