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 the

recirculation 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.
