To defog or defrost the outside rear
view mirrors, push the switch.
The engine switch must be in the “ON”
position.
The heater panels in the outside rear view
mirrors will quickly clear the mirror sur-
faces. An indicator light will illuminate to
indicate the defoggers are operating.
On some models, the front windshield wip-
er de−icer also operates simultaneously by
this switch. On vehicles with the front
windshield wiper de−icer, the front wind-
shield wiper blades will be de−iced.
Push the switch once again to turn the
defoggers off.
The system will automatically shut off af-
ter the defoggers have operated about 15
minutes.
CAUTION
Since the mirror surfaces can get hot,
do not touch them when the switch
is on.
Make sure you turn the defoggers off
when the mirror surfaces are clear or the
wiper blades have de−iced. Leaving the
defoggers on for a long time could cause
the battery to discharge, especially during
stop−and−go driving. The defoggers are
not designed for drying rain water or for
melting snow.
If the outside rear view mirrors are heavi-
ly coated with ice, use a spray de−icer
before operating the switch.
