CAUTION
Since the mirror surfaces can get hot,
do not touch them when the switch
is on.
Make sure you turn the mirror heaters off
when the mirror surfaces are clear. Leav-
ing the mirror heaters on for a long time
could cause the battery to discharge, es-
pecially during stop −and− go driving. The

mirrors will also quickly clear the sur-
faces.
Push the switch once again to turn the
defogger off.
The system will automatically shut off af-
ter the defoggers have operated about 15
minutes. Make sure you turn the defoggers off
when the surfaces are clear. 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.

The inside of the lens of exterior lights
such as headlights may temporarily fog up
when the lens becomes wet in the rain or
in a car wash. This is not a problem
because the fogging is caused by the
temperature difference between the outside
and inside of the lens, just like the
windshield fogged up in the rain. However,
if there is a large drop of water on the
inside of the lens, or if there is water
pooled inside the light, contact your
Toyota dealer. Light bulbsBulb
