Controls for ventilated front seats
The ventilation system consists of fans in the
seats and backrests that draw air through the
seat upholstery. The cooling effect increases
as the air in the passenger compartment
becomes cooler.
The level of ventilation is adjusted on the con-
trol panel on the side of the seat. The fans can
be set to three speeds.
To start seat ventilation:

Press briefly on
.
To gradually increase ventilation:

Press briefly on
.For maximum ventilation:

Hold down
for approximately 2 sec-
onds.
To gradually decrease ventilation:

Press briefly on
.
To switch off ventilation:

Hold down
for approximately 2 sec-
onds.
The ventilation can be used at the same time
as seat heating*, for example, to help dry damp
clothing.
NOTE
•Seat ventilation cannot be started if the
temperature in the passenger compart-
ment is below 41°F (5°C).
•Seat ventilation should be used with
caution by people who are sensitive to
drafts. A moderate ventilation level
should be set if the function is used for
extended periods.

Functions
A/C – ON/OFF
•The air conditioning functions only at tem-
peratures above 32°F (0°C).
•While the Defroster function is selected,
the air conditioning is temporarily activated
to dehumidify the air, even if you have man-
ually switched the air conditioning off. Thiswill only function if the blower is not
switched off.
Press the switch to turn the air conditioning on
or off. The "ON" or "OFF" LED will light up to
indicate if the system is switched on or off.
Other functions will still be regulated automat-
ically (if the AUTO switch is on).
Interior air quality sensor*
Some vehicles are equipped with a multifilter
and air quality sensor. The filter separates
gases and particles, thereby reducing the
amounts of odors and contaminants entering
the vehicle. The air quality sensor detects
increased levels of contaminants in the outside
air. When the air quality sensor detects conta-

minated outside air, the air intake closes and
the air inside the passenger compartment is
recirculated, i.e. no outside air enters the vehi-
cle. The filter also cleans recirculated passen-
ger compartment air.
When the ECC system is in the AUTO mode,
the green LED will be on.
Recirculation
Press this switch to engage the recirculation
function (air in the passenger compartment
recirculates – no fresh air enters the compart-
ment). The LED in the switch will light up to
indicate that the function is engaged.
•Use this function if the outside air is con-
taminated with exhaust gases, smoke, etc
or to heat/cool the vehicle quickly.
•Recirculation should not be used for more
than 15 minutes. If your windows begin to
fog or mist, make sure that the recirculation
function is switched off.
•Selecting Defroster automatically
switches recirculation off.
•Timer mode activation: (Vehicles equipped
with the Interior Air Quality system have no
timer mode) Press and hold the recircula-
tion button for at least 3 seconds to acti-
vate a recirculation timer mode. The amber
LED in the recirculation button will flash 5
times to show that the timer mode is being
activated. In timer mode, each time therecirculation button is pressed, the climate
control system will recirculate the air in the
passenger compartment for
5 – 12 minutes, depending on the outside
air temperature, and then revert back to
fresh air.
•Timer mode deactivation: Press and hold
the recirculation button for 3 seconds. The
amber LED in the recirculation button will
illuminate steadily for 5 seconds to show a
return to "normal" mode.
•In normal mode, when the recirculation
button is pressed, the climate control sys-
tem will recirculate the air in the passenger
compartment until the recirculation button
is pressed again.
•Timer mode memory: If the vehicle is
turned off while timer mode is active, timer
mode will still be active when the vehicle is
restarted.
AUTO
This function automatically regulates the
Electronic Climate Control system so that
the selected temperatures are maintained.
The blower, heating, air distribution (air
flow), air conditioning, and optional air qual-
ity sensor are controlled. If you prefer to man-
ually set any of these functions, the remaining
functions will still be controlled automatically.
Pressing the AUTO button overrides any set-
tings that were previously made manually.
Air distribution
G027267
•Air flow to windows
•Air through panel vents
•Air through floor vents
Press AUTO to automatically regulate air flow
or press any combination of the controls
shown in the illustration to manually adjust air
flow. An LED in the switch will light up if an air
flow control has been pressed.
Passenger compartment temperature

Measures the temperature in the compart-
ment.

will light up to indicate that the defrost function
is engaged.
•Blower speed increases automatically and
the air conditioning will switch on (if not
already on and if the passenger compart-
ment blower is not turned off) to dehumid-
ify the air in the passenger compartment.
•Recirculation will not function while defrost
is engaged.
The climate system will return to its previous
settings when the defroster function is
switched off.
Rear window and door mirror
defrosters
This function defrosts/deices the rear window
and door mirrors. The LED in the switch will
light up to indicate that the heating function is
engaged. For additional information on this
function see page 74.
Never use ice scrapers made of metal as they
can easily scratch the mirror surface.
Heated front seats*
1. Press the switch once for maximum seat
heating. Both LEDs in the switch will be lit.
2. Press the switch a second time for comfort
heating. One LED in the switch will be lit.3. Press the switch a third time to turn the
heating off completely. The LED will go off.
The seat heating for the passenger seat should
be switched off when the seat is not occupied.

> The symbol in the button will illuminate.To switch off rear seat heating:

Press the button.
> The symbol in the button will go out.
Temperature
These controls are used to individually set the
temperature for both sides of the passenger
compartment. Please note that the compart-
ment will not be heated or cooled faster by set-
ting the temperature higher or lower than nec-
essary.
Set the control to the temperature you prefer.
Blower control1
Turn the control clockwise to increase or coun-
terclockwise to decrease the blower speed.
Pressing the AUTO switch will automatically
regulate blower speed and override manual
adjustment.

or:
Select one of the following three functions by
pressing 1, 2 or 3 times.
1.
The AUT LED lights. The air quality sensor
is now activated.
2. No LED lights. Recirculation is not acti-
vated unless needed to cool the passenger
compartment in a warm climate.
3.
The MAN LED lights. Recirculation is now
activated.
Keep in mind the following:
•Make it a rule to have the air quality sensor
activated at all times.
•Recirculation is limited in cold climates to
avoid fogging.
•If window fogging occurs, you should
deactivate the air quality sensor. Also use
the defroster functions for the windshield,
side windows and rear window, see
page 98.
•The filter should be changed at the inter-
vals recommended in the service sched-
ule. However, if the vehicle is used in a
severely contaminated environment, it may
be necessary to change the filter more fre-
quently.

WARNING
•Do not adjust the seat while driving. The
seat should be adjusted so that the
brake pedal can be depressed fully. In
addition, position the seat as far rear-
ward as comfort and control allow.
•Check that the seat is securely locked
into position after adjusting.
Folding the backrests in the front seat
G014805
The front passenger seat backrest can be
folded to a horizontal position to make room for
a long load. Fold the backrest as follows:1. Move the seat as far back as possible.
2. Adjust the backrest to the upright position.
3. Lift the catches on the rear of the backrest.
4. Without releasing the catches, push the
backrest forward.
5. Move the seat as far forward as possible
so that the head restraint slides under the
glove compartment.
WARNING
•When transporting long objects, cover
sharp edges on the load to help prevent
injury to occupants. Secure the load to
help prevent shifting during sudden
stops.
•When the seat's backrest is returned to
the upright position, push and pull it to
be sure that it is securely locked in this
position.
