    2. The rear window defogger wire is attached to the inside of the rear window and defogs the window surface quickly when the rear window defogger switch is pressed. The indicator light on the switch illuminates while the system is operating. This system the rear window defogger switch is pressed turns off.*2

      • *1: w/ Timer

      • *2: w/o Timer

      Tip:

      • If both of the following conditions are met after approximately 15 minutes from when the window defogger system was activated, the window defogger system continues to operate up to approximately 45 minutes.
