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.

REAR POWER DROP GLASS OPERATION (IF EQUIPPED)

• Rear power drop glass system is operable during the retained power operation timer after turning ignition

switch ON and OFF.

• Rear power drop glass switch can open/close the rear power drop glass.

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.
