How to use it

Step by step.

  1. 01

    Turn the power switch off, remove every key from the cabin and close all doors except the power back door.

  2. 02

    Carry the physical electronic key and press the close-and-lock Walk-Away switch on the lower part of the open back door.

  3. 03

    Listen for the different standby buzzer that confirms the request was accepted.

  4. 04

    While the buzzer is sounding, move away from the back door and its key-detection area.

  5. 05

    Wait for the power back door to close and for the emergency-flasher/buzzer lock confirmation.

  6. 06

    Before leaving, physically verify that the back door and side doors are locked.

Important limits

  • A Digital Key alone cannot operate this function; carry the vehicle's physical electronic key.
  • The standby request cancels if you do not move away within approximately 30 seconds.
  • Approaching the back door again with the electronic key stops the operation and unlocks the doors.
  • Keep people and objects clear because the liftgate begins moving after you leave its detection area.
If it does not work

Quick checks.

  • ✓Confirm the function is enabled, the power switch is off, the brake is not depressed and every side door is closed.
  • ✓Keep the electronic key on your person rather than in a bag on the ground, and move decisively out of the rear detection area while the standby buzzer sounds.
  • ✓If the back door encounters an obstruction or jam protection activates, clear the path and restart the sequence.
