The defroster will automatically turn off after approxi-
mately 10 minutes. For an additional five minutes of
operation, press the button a second time. To prevent
excessive battery drain, use the defroster only when the
engine is operating.
CAUTION!
Use care when washing the inside of the rear window
to prevent damage to heating elements. Use a soft
cloth and a mild washing solution, wiping parallel to
the heating elements. Also, keep all objects a safe
distance from the window to prevent damaging the
heating elements.
