The windshield wiper deicer operates only when the ignition switch is in the “ON” position.

To turn on the windshield wiper deicer, push the control switch. The indicator light located on the switch illuminates while the windshield wiper deicer is operating.

To turn it off, push the control switch again.

It also turns off when the ignition switch is turned to the “Acc” or “LOCK” position.

The windshield wiper deicer will automatically shut off after approximately 15 minutes. If the windshield wiper blades have been deiced completely before that time, push the control switch to turn it off. If deicing is not complete, you have to push the control switch to turn it on again.

Your SUBARU dealer can set your windshield wiper deicer to the continuous operation mode. Contact your SUBARU dealer for details.

Once the windshield wiper deicer has been set to the continuous operation mode, it should be in the continuous operation mode at any time when the control switch is pushed to the “ON” position.

If the battery voltage drops below the permissible level, continuous operation of the windshield wiper deicer is canceled and the system stops operating.

CAUTION

To prevent the battery from being discharged, do not operate the windshield wiper deicer continuously for any longer than necessary.

NOTE

• Turn on the windshield wiper deicer 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 effectively.

• While the windshield wiper deicer is in the continuous operation mode, if the vehicle speed remains at 9 mph (15 km/h) or less for 15 minutes, the windshield wiper deicer automatically stops operating.
