Windshield wiper deicer (if equipped)
To prevent the battery from being discharged,
do not operate the windshield wiper deicer con-
tinuously for any longer than necessary.
The windshield wiper deicer operates only when the
ignition switch is in the “ON” position.
Before turning on the windshield wiper deicer, remove
any snow from the windshield. To turn on the wind-
shield wiper deicer, push the switch. The indicator light
located on the switch lights up while the windshield
wiper deicer is operating.
The windshield wiper deicer will automatically shut off
after about 15 minutes. If the wiper blades have been
deiced completely before that time, push the switch to
turn it off. It also turns off when the ignition switch is
turned to the “ACC” or “LOCK” position. If deicing is
not complete when you restart your vehicle, you have
to push the switch to turn the deicer on again.
