POWER WINDOW OPERATION
• Power window system activated by the power window swit ch when the ignition switch is in the ON position
or during the retained power operation after ignition switch turns OFF.
• Power window main switch (driver side) can open/close all windows.
• Front & rear power window switch can open/close the corresponding windows.
• If door glass receives resistance that is more than the specified value and the power window is in the AUTO-
UP operation (Front LH & RH), power window will move in the reverse direction (Anti-Pinch Function).
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.
• AUTO function does not operate if 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 FUNCTION
Ground circuit inside power window main switch shuts off when power window lock switch is ON. This inhibits
power window switch operation except with the power window switch.
ANTI-PINCH OPERATION (FRONT LH & RH)
• 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 (5.9 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.
• Power window switch controls to lower the window glas s for 150 mm (5.9 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 dire ction 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.

SYSTEM
• 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 LH & RH)
Front power windows open when the unlock button on Intelligent 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 activate, keyless power window down function cannot be operated.
Fail-safeINFOID:0000000009460898
FAIL-SAFE CONTROL
Switches to fail-safe control when malfunction is det ected in encoder signal that detects UP/DOWN speed and
direction of door glass. Switches to fail-safe cont rol when an error beyond the regulation value is detected
between the fully closed position and the actual position of the glass.
It changes to condition before initialization and the fo llowing functions do not operate when switched to fail-
safe control:
• Auto-up operation
• Anti-pinch function
• Retained power function
Perform initial operation to recover when switched to fa il-safe mode. However, it switches back to fail-safe
control when malfunction is found in power window switch or in motor.
Malfunction Malfunction condition
Pulse sensor malfunction When only one side of pulse signal is being detected for more than the specified value.
Both pulse sensors mal-
function When both pulse signals have not been detected for more than the specified value during glass
open/close operation.
Pulse direction malfunc-
tion When the pulse signal that is detected during glass open/close operation detects the opposite con-
dition of power window motor operating direction.
Glass recognition position
malfunction 1 When it detects the error between glass fully closed position in power window switch memory and
actual fully closed position during glass open/close operation is more than the specified value.
Glass recognition position
malfunction 2 When it detects pulse count more that the value of glass full stroke during glass open/close opera-
tion.
Malfunction of not yet up-
dated closed position of
glass When glass open/close operation is continuously performed without fully closing more that the spec-
ified value (approximately 10 strokes).
