Trunk / Liftgate: Description and Operation

Power Tailgate System Description

The power tailgate can be opened and closed automatically from the driver's power tailgate switch (located on the driver's side of the dashboard), or by using the keyless transmitter. The power tailgate inside switch will only close the tailgate. 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 power tailgate switch, or the keyless transmitter under the following conditions:

- Tailgate is fully closed (full-latched position is detected).
- All door lock knob switches show UNLOCKED with the HDS.
- The remote unlock button is pressed twice, and then the tailgate button is pressed and held for 2 seconds (unless customized setting is set to unlock all doors).
- Shift lever is in P position.
- Vehicle speed is less than 1 mph (2 km/h).
- Closer unit detects the neutral position.
- Battery voltage (VBU) is more than 11 V.
- System is not in fail-safe mode.
- For keyless transmitter, the ignition key is not in the ignition switch.

CLOSE: The power tailgate can be closed by operating the driver's power tailgate switch, the power tailgate inside switch, or the keyless transmitter under the following conditions:

- Tailgate is fully open.
- Pinch sensor detects no obstruction.
- Closer unit detects the neutral position.
- Battery voltage (VBU) is more than 11 V.
- System is not in fail-safe mode.

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 when the shift lever is in any position other than P, or the vehicle speed exceeds 1 mph (2 km/h), 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 .
