• Sliding door control unit operates sliding door lock release actuator, and then operates automatic sliding

door motor to move sliding door to the fully open position.

• When sliding door handle is operated again during auto open operation, sliding door control unit stops auto

open operation and operates sliding door in reverse direction to the fully closed position.

• When child lock is in the lock status, auto open function does not operate even when sliding door inside han-

dle is operated.

Sliding Door Open/close Switch and Sliding Door One-touch Open/close Switch Operation

• When sliding door open/close switch or sliding door one-touch open/close switch is operated, sliding door

control unit sounds automatic sliding door warning buzzer as a reminder.

• Sliding door control unit operates clutch and sliding door lock release actuator, and it releases sliding door

latch (only when sliding door is fully closed).

• Sliding door control unit detects half latch switch signal and full latch switch signal. When judging that sliding

door latch is released, sliding door control unit operates automatic sliding door motor and it moves sliding
door to the fully open position.

• When switch is operated again during auto open operation, sliding door control unit stops auto open opera-

tion and operates sliding door in reverse direction to the fully closed position.

Intelligent Key Button Operation

• When sliding door open button of Intelligent Key is operated, BCM transmits automatic sliding door operate

request signal to sliding door control unit via CAN communication.

• When automatic sliding door operate request signal is received from BCM, sliding door control unit sounds

automatic sliding door warning buzzer as a reminder.

• Sliding door control unit operates clutch and sliding door lock release actuator, and it releases sliding door

latch. (Only when sliding door is fully closed.)

• Sliding door control unit detects half latch switch signal and full latch switch signal. When judging that sliding

door latch is released, sliding door control unit operates automatic sliding door motor and it moves sliding
door to the fully open position.

• When Intelligent Key button is operated again during auto open operation, sliding door control unit stops

auto open operation and operates sliding door in reverse direction to the fully closed position.

AUTO OPEN/CLOSE FUNCTION (CLOSE OPERATION)

• Sliding door control unit sounds automatic sliding door warning buzzer as a reminder, when operation of slid-

ing door handle, sliding door open/close switch, sliding door one-touch open/close switch, or Intelligent Key
button is detected while sliding door is in the fully open status.
NOTE:
The function may not be operated unless sliding door handle is pulled continuously.

• Sliding door control unit operates clutch and sliding door lock release actuator and it performs latch release

operation, so that sliding door control unit can judge whether sliding door latch is in released status.

• Sliding door control unit operates automatic sliding door motor and moves sliding door to half latch status,

when sliding door control unit judges sliding door handle switch ON status and latch release status accord-
ing to operation of sliding door release actuator.

• Sliding door control unit detects half latch status according to half latch switch. Sliding door control unit oper-

ates sliding door auto closure function and closes sliding door to the fully closed position.

• When sliding door handle, each switch, or Intelligent Key button is operated again during auto close opera-

tion, sliding door control unit stops auto close operation and operates sliding door in reverse direction to the
fully open position.
