Step by step.
- 01
Turn the power switch off, remove every key from the cabin and close all doors except the power back door.
- 02
Carry the physical electronic key and press the close-and-lock Walk-Away switch on the lower part of the open back door.
- 03
Listen for the different standby buzzer that confirms the request was accepted.
- 04
While the buzzer is sounding, move away from the back door and its key-detection area.
- 05
Wait for the power back door to close and for the emergency-flasher/buzzer lock confirmation.
- 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.
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.
