ANTI-PINCH OPERATION
 Pinch foreign material in the door glass during AUTO-U P operation, and it is the anti-pinch function that low-
ers the door glass 150 mm (5.91 in) or 2 seconds when detected.
 Encoder continues detecting the movement of power window motor and transmits to power window switch
as the encoder pulse signal while power window motor is operating.
 Resistance is applied to the power window motor ro tation that changes the frequency of encoder pulse sig-
nal if foreign material is trapped in the door glass.
 Front power window switch LH/RH and rear power wi ndow control unit LH/RH controls to lower the window
glass for 150 mm (5.91 in) or 2 seconds after it detects encoder pulse signal frequency change.
OPERATION CONDITION
 When all door glass AUTO-UP operation is performed ( anti-pinch function does not operate just before the
door glass closes and is fully closed)
NOTE:
Depending on environment and driving conditions, if a similar impact or load is applied to the door glass, it
may lower.
KEY CYLINDER SWITCH OPERATION
Hold the door key cylinder to the LOCK or UNLOCK direction for more than 1 second to OPEN or CLOSE front
power windows when ignition switch is OFF. In addition, it stops when key position is moved to NEUTRAL
when operating.
OPERATION CONDITION
 Ignition switch OFF
 Hold door key cylinder to LOCK position for more than 1 second to perform CLOSE operation of the door
glass.
 Hold door key cylinder to UNLOCK position for more than 1 second to perform OPEN operation of the door glass.
KEYLESS POWER WINDOW DOWN OPERATION
Front power windows open when the unlock button on Intelli gent Key is activated and kept pressed for more
than 3
(NOTE) seconds with the ignition switch OFF. The wi ndows keep opening if the unlock button is continu-
ously pressed.
The power window opening stops when the following operations are performed:
 When the unlock button is kept pressed more than 15 seconds.
 When the ignition switch is turned ON while the power window opening is operated.
 When the unlock button is released.
While retained power operation is activated, ke yless power window down function cannot be operated.
NOTE:
Keyless power window down operation mode can be changed by “PW DOWN SET” mode in “WORK SUP-
PORT”. Refer to DLK-56, "CONSULT-III F unction (INTELLIGENT KEY)"
.
NOTE:
Use CONSULT-III to change settings.
