03 Climate Electronic climate control, ECC • Timer mode activation: (vehicles with the Interior Air Quality system have no timer mode) Press and hold the recirculation button for at least 3 seconds to activate 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. Interior air quality sensor (option) Some vehicles are equipped with a multifilter and air quality AUT MAN 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 contaminated outside air, the air intake closes and the air inside the passenger compartment is recirculated, i.e. no outside air enters the vehicle. The filter also cleans recirculated passenger compartment air. When the ECC system is in the AUTO mode, the green LED in the button will be on. 2. No LED lights. Recirculation is not activated 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 03 • 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. • 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. • If fogging occurs, use the defroster functions for the windshield, side windows and rear window, see page 66. The filter should be changed at the intervals recommended in the service schedule. However, if the vehicle is used in a severely contaminated environment, it may be necessary to change the filter more frequently. • In normal mode, when the recirculation button is pressed, the climate control system will recirculate the air in the passenger compartment until the recirculation button is pressed again. Operation Press AUTO to operate the air quality sensor (normal setting). or Select one of the following three functions by pressing the recirculation button 1, 2 or 3 times. 1. The AUT LED lights. The air quality sensor is now activated. • 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. 91
