POWER WINDOW OPERATION
• Power window system is operable during the retained power operation timer after turning ignition switch ON
and OFF.
• Main power window and door lock/unlock switch can open/close all windows.
• Power window and door lock unlock switch RH & rear power window switches LH and RH can open/close
the corresponding windows.
POWER WINDOW AUTO-OPERATION (FRONT LH & RH)
• AUTO UP/DOWN operation can be performed when main power window and door lock/unlock switch &
power window and door lock/unlock switch RH turns to AUTO.
• 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.
• 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.
RETAINED POWER OPERATION
• Retained power operation is an additional power supply function that enables power window system to oper-
ate during the 45 seconds even when ignition switch is turned OFF
Retained power function cancel conditions
• Front door CLOSE (door switch OFF)
→
OPEN (door switch ON).
• When ignition switch is ON.
• When timer time passes. (45 seconds)
POWER WINDOW LOCK
Ground circuit inside main power window and door lock/unlock switch shuts off when power window lock
switch is ON. This inhibits power window switch operation except with the main power window and door lock/
unlock switch.
ANTI-PINCH OPERATION (FRONT LH & RH)
• Pinch foreign material in the door glass during AUTO-UP 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 rotation that changes the frequency of encoder pulse sig-
nal if foreign material is trapped in the door glass.
• Power window switch 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 driver’s 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

POWER WINDOW SYSTEM
• Hold driver’s door key cylinder to LOCK position for more than 1 second to perform CLOSE operation of the
door glass.
• Hold driver’s 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 LH & RH)
Front power windows open when the unlock button on Intelligent Key or keyfob is activated and kept pressed
for more than 3
(NOTE)
seconds with the ignition switch OFF. The windows keep opening if the unlock button is
continuously 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, keyless power window down function cannot be operated.
NOTE:
Keyless power window down operation mode can be changed by “P/W DOWN DELAY” mode in “WORK SUP-
PORT”. Refer to
BCS-23, "INTELLIGENT KEY : CONSULT Function (BCM - INTELLIGENT KEY)"
with Intelli-
gent Key or
