Make sure you turn the defogger off when
the window is clear. Leaving the defogger
on for a long time could cause the battery
to discharge, especially during stop−and−
go driving. The defogger is not designed
for drying rain water or for melting snow.
NOTICE
When cleaning the inside of the rear
window, be careful not to scratch or
damage the heater wires or connec-
tors.
