To heat the mirrors and defog the rear window, press the rear defogger switch located in your air conditioning control unit. An indicator light above the rear defogger switch will be illuminated while the rear defogger and heated mirrors are on.
After the rear defogger switch is pressed the first time, the heated mirrors and defogger will remain on for 15 minutes or until either the defogger switch is turned off or the ignition switch is turned to either "ACC' or "LOCK" position.
To run the heated mirrors and defogger for more than 15 minutes, wait until the defogger indicator light turns off, and then push the rear defogger switch again. The defogger will be on for 7 1/2 more minutes or until either the defogger switch is turned off or the ignition switch is turned to either the "ACC" or "LOCK" position.
