To turn them off, press the control switch 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 outside mirrors have been cleared and the windshield wiper blade rubbers have been deiced completely before that time, press the control switch to turn them off.

It is possible to set the defogger and deicer system for the continuous operation mode by operating the multi information display. For details, refer to "Defogger" .

NOTE

•  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 effectively.
•  While the defogger and deicer system 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 deicer system automatically stops operating.

  However, the rear window defogger system and outside mirror defogger system maintain continuous operation in this condition.

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