Toyota 4Runner 2003 Operating Manual page 115

If the back window is not fully closed, the
back window defogger will not work. Make
sure the back window is fully closed when
using the back window defogger.
If the back window is opened while the
defogger is working, the defogger will au-
tomatically turn off. Even if the back win-
dow is fully closed after that, the defogger
will not automatically turn on.
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.
CAUTION
On some models, since the mirror
surfaces can get hot, do not touch
them when the defogger switch is on.
NOTICE
When cleaning the inside of the back
window, be careful not to scratch or
damage the heater wires or connec-
tors.
