To activate simultaneously the rear win- dow defogger, outside mirror defogger (if equipped) and windshield wiper deicer (if equipped), press the control button that is located on the climate control panel. The indicator light on the control button illumi- nates while the defogger and deicer system is activated.

To turn them off, press the control button again. They also turn off when the ignition switch is turned to the “ACC” or “LOCK”/ “OFF” position.

The defogger and deicer system will automatically shut off after approximately 15 minutes. If the rear window and the outside mirrors have been cleared and the windshield blade rubbers have been

deiced completely before that time, press the control button to turn them off.

For climate control system (type B and C), it is possible for the defogger and deicer system to be set to continuous operation mode by a SUBARU dealer. Consult your SUBARU dealer for details.

Also, for models with a combination meter display (color LCD), it is possible to set the defogger and deicer system for the con- tinuous operation mode. For details, refer to “Vehicle Setting”  3-39.

Turn on the defogger and deicer system if the wipers are frozen to the windshield.

If the windshield is covered with snow, remove the snow so that the windshield wiper deicer works effec- tively.

While the defogger and deicer sys- tem is in the continuous operation mode:

If the vehicle speed remains at 9 mph (15 km/h) or lower for 15 minutes, the windshield wiper dei- cer system automatically stops op- erating. However, the rear window defogger system and outside mirror defogger system maintain continu- ous operation in this condition.

If the vehicle battery voltage drops below the permissible level, continuous operation of the defog- ger system and deicer system is canceled and the system stops operating.
