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
Carry the registered key outside the vehicle and switch vehicle power OFF.
- 02
Confirm all doors are closed and the liftgate is open but not already moving.
- 03
Clear the liftgate path and press the door-lock switch on the liftgate, not the adjacent close-only switch.
- 04
Confirm the single lock/hazard acknowledgement, followed by the pre-close flashes and long warning sound.
- 05
Step back, watch the liftgate fully close and confirm the final lock indication.
Important limits
- This function requires the key to be carried outside, vehicle power OFF, all doors closed and the liftgate not already moving.
- The door-lock switch and close-only switch are adjacent but perform different actions.
- Always watch the gate; the jam-safe system may not detect every object.
Quick checks.
- ✓If the gate closes without locking, the close-only switch was likely pressed; repeat using the door-lock switch.
- ✓If no lock confirmation occurs, make sure the key is outside and every side door is fully closed.
- ✓If the liftgate is moving, stop it before trying the close-and-lock command again.
