    The power tailgate can be opened and closed automatically by operating the driver's door power tailgate switch, inside tailgate switch (for close), or the keyless transmitter. The power tailgate has two safety functions for safeguarding passengers: obstruction detection, and fall-down detection.

    Basic Operation


    OPEN: The power tailgate can be opened by operating the driver's door power tailgate switch or the keyless transmitter under the following conditions:
    • Tailgate is fully closed (full-latched position is detected).
    • All door lock knob switch is in UNLOCKED.
    • Parking brake is applied (M/T).
    • Shift lever is in Park position (A/T).
    • Vehicle speed is less than 2 km/h (1.2 mph).
    • Closer unit detects the neutral position.
    • Battery voltage (VBU) is more than 11 V.
    • System is not in fail-safe mode.
    • For keyless transmitter, ignition key is removed from the ignition switch.

    CLOSE: The power tailgate can be closed by operating the driver's door power tailgate switch, inside tailgate switch, or the keyless transmitter under the following conditions:
    • Tailgate is fully open.
    • Pinch sensor detects no obstruction.
    • Closer unit detects the neutral position.
    • Half latch switch is ON.
    • Battery voltage (VBU) is more than 11 V.
    • System is not in fail-safe mode.
    • For keyless transmitter, ignition key is removed from the ignition switch.
    • 1 second or more after the keyless transmitter or the driver's door power tailgate switch is pressed.

    Obstruction Detection Function

    If any obstruction is detected while the tailgate is automatically opening or closing, the tailgate will stop and the reverse operation is activated. An obstruction is detected by the tailgate pinch sensor and the pulser in the drive unit. If the obstruction is detected or the vehicle speed exceeds 2 km/h (1.2 mph), the tailgate stops moving immediately.

    Fall-down Detection Function

    This function prevents the tailgate from suddenly falling down because of an accumulation of snow, or other causes. If the pulser in the drive unit detects abnormal pulses, the tailgate starts to open. If this operation is activated twice, the tailgate will close automatically. If the obstruction detection function detects any obstruction several times during this fall-down detection function, the tailgate stops moving.
    NOTE: If the tailgate falls repeatedly, replace the tailgate support strut .
    A: Auto open action completed
    B: Tailgate falling is detected
    C: Clutch reconnect when falling is detected
    D: Auto open action (power tailgate motor reverse action)
    E: Close function activated from fully open position
