POWER WINDOW OPERATION
 Power window system is activated by power window switch operation when ignition switch turns ON, or dur-
ing the retained power operation after ignition switch turns OFF.
 Power window main switch can open/close door glass.
 Front and rear power window switch can open/close the corresponding door glass.
 Power window lock switch can lock all power windows other than driver seat.
 All power windows close when pressing Intelligent Ke y lock button or unlock button for 3 seconds.
 If door glass receives resistance that is the specifi ed value or more while power window of each seat is in
AUTO-UP operation, power window operates in the reverse direction.
 Power window serial link transmits the signals from power window main switch to each power window switch.
 AUTO-UP/DOWN operation can be performed when front power window switch turns to AUTO.
POWER WINDOW AUTO-OPERATION
 AUTO-UP/DOWN operation can be performed when each power window motor turns to AUTO.
 Encoder continues detecting the movement of power window motor and output the encoder pulse signal to
power window switch while power window motor is operating.
 Power window switch reads the changes of encoder signal and stops AUTO operation when door glass is at
fully opened/closed position.
 Power window motor is operable in case encoder is malfunctioning.
 AUTO function does not operate if encoder is malfunctioning.
POWER WINDOW SERIAL LINK
Power window main switch, front power window switch (passenger side), rear power window switch LH/RH
and BCM transmit and receive the signal by power window serial link.
