Climate control system – general information

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 acti- vate the blower, turn the control to the desired setting.

The climate system blower may start automat- ically during a period of up to approximately 50 minutes after the ignition has been turned off to remove condensation in the A/C evapo- rator. It will run for 15 minutes and switch 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 remove condensation in the A/C evaporator.

The following points pertain if the ignition is on 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 blower speed will be reduced to avoid battery drain.

You can reset the blower speed at any time. Please be aware that the system has been designed to reduce the blower's speed again after 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 instrument panel (see page 58) will also light up.

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 battery drain.
