Know what kind of control to look for.
This original category diagram is an orientation aid, not a picture of your exact trim. Use the written labels and your vehicle manual to identify the real control.
Step by step.
- 01
Turn the engine or power switch off, remove all keys from the cabin and close every door except the power back door.
- 02
Carry the physical electronic key and press the Close & Lock Walk-Away switch on the lower part of the open liftgate.
- 03
Listen for the distinct standby buzzer, then move away from the liftgate while it is sounding.
- 04
Remain away while the side doors lock and the liftgate closes and locks.
- 05
Confirm the final buzzer and emergency-flasher signals, then physically verify the vehicle is locked.
Important limits
- The standby request cancels if the key does not leave the rear detection area within 30 seconds.
- Approaching again with the key stops the liftgate and unlocks the doors.
- A Digital Key alone cannot provide every power-back-door Walk-Away function; use the physical electronic key.
Quick checks.
- ✓If the request is not accepted, verify the other doors are closed, no key remains inside, the brake is released and the vehicle is off.
- ✓Move directly away while the standby buzzer sounds; direction, key position and radio conditions can prevent detection.
- ✓If jam protection stops closure, remove the obstruction and retry only after confirming normal liftgate movement.
