Climate system blower
The climate system blower will be automati- cally switched off when the engine is not run-ning (even if the ignition key is in position I or
II ) to avoid unnecessary battery drain. To
activate the blower, turn the control to thedesired setting. The climate system blower may start auto- matically during a period of up to approxi-mately 50 minutes after the ignition has beenturned off to remove condensation in the A/Cevaporator. It will run for 15 minutes andswitch off automatically.
Passenger compartment blower
Approximately 50 minutes after the ignition is turned off, the blower may come on automati-cally, and run for seven minutes, to removecondensation in the A/C evaporator.
Blower function to reduce battery drain
The climate system's blower functions nor- mally while the engine is running. However, when the engine is switched off (even if the ignition is switched to positions I
or II), the blower control will be automatically
switched off to avoid unnecessary batterydrain. The following points pertain if the ignition ison but the engine in not running:
• To restart the blower, turn the control knob to the setting of your choice.
• After approximately 2 minutes, the blowerspeed will be reduced to avoid batterydrain.
You can reset the blower speed at any time. Please be aware that the system has beendesigned to reduce the blower's speed againafter 2 minutes, until the engine is started. If the battery becomes drained: • LOW BATTERY, FAN IS REDUCED
will
be displayed in the text window in the instrument panel.
• The yellow warning light in the instrumentpanel (see page 58) will also light up.

Controls for ventilated front seats
The ventilation system consists of fans in the seats and backrests that draw air through theseat upholstery. The cooling effect increasesas the air in the passenger compartmentbecomes cooler. The level of ventilation is adjusted on the con- trol panel on the side of the seat. The fanscan 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 drydamp clothing.
NOTE
• Seat ventilation cannot be started if the temperature in the passenger com-partment is below 41°F (5°C).
• Seat ventilation should be used withcaution by people who are sensitive todrafts. A moderate ventilation levelshould be set if the function is used forextended periods.

Functions
A/C – ON/OFF
•The air conditioning functions only at temperatures above 32°F (0°C).
• While the Defroster function is selected,the air conditioning is temporarily acti-vated to dehumidify the air, even if youhave manually switched the air condition- ing off. This will only function if the bloweris 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 auto-matically (if the AUTO switch is on).
Interior air quality sensor*
Some vehicles are equipped with a multifilter and air quality sensor. The filter separatesgases and particles, thereby reducing theamounts of odors and contaminants enteringthe vehicle. The air quality sensor detectsincreased levels of contaminants in the out-side air. When the air quality sensor detects

contaminated outside air, the air intake closes and the air inside the passenger compart-ment is recirculated, i.e. no outside air entersthe vehicle. The filter also cleans recirculatedpassenger 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 compartmentrecirculates – no fresh air enters the compart-ment). The LED in the switch will light up toindicate 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 morethan 15 minutes. If your windows begin tofog or mist, make sure that the recircula-tion function is switched off.
• Selecting
Defroster automatically
switches recirculation off.
• Timer mode activation: (Vehicles equip-ped with the Interior Air Quality systemhave no timer mode) Press and hold therecirculation button for at least 3 secondsto activate a recirculation timer mode.The amber LED in the recirculation buttonwill flash 5 times to show that the timermode is being activated. In timer mode, each time the recirculation button ispressed, the climate control system willrecirculate the air in the passenger com-partment for 5 – 12 minutes, dependingon the outside air temperature, and thenrevert back to fresh air.
• Timer mode deactivation: Press and holdthe recirculation button for 3 seconds.The amber LED in the recirculation buttonwill illuminate steadily for 5 seconds toshow a return to "normal" mode.
• In normal mode, when the recirculationbutton is pressed, the climate controlsystem will recirculate the air in the pas-senger compartment until the recircula-tion button is pressed again.
• Timer mode memory: If the vehicle isturned off while timer mode is active,timer mode will still be active when thevehicle is restarted.
AUTO
This function automatically regulates the Electronic Climate Control system so that theselected temperatures are maintained. Theblower, heating, air distribution (air flow), airconditioning, and optional air quality sensorare controlled. If you prefer to manually setany of these functions, the remaining func-tions will still be controlled automatically.Pressing the
AUTO button overrides any set-
tings that were previously made manually.

OperationPress to operate the air quality sensor (nor-mal setting). or: Select one of the following three functions by pressing 1, 2 or 3 times.
1. The AUT LED lights. The air quality sen-
sor is now activated.
2. No LED lights. Recirculation is not acti- vated unless needed to cool the passen- ger 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 sen- sor activated at all times.
• Recirculation is limited in cold climates toavoid fogging.
• If window fogging occurs, you shoulddeactivate the air quality sensor. Also usethe defroster functions for the windshield,side windows and rear window, seepage 98. •
The filter should be changed at the inter-vals recommended in the service sched-ule. However, if the vehicle is used in aseverely contaminated environment, itmay be necessary to change the filtermore frequently.
