Step by step.
- 01
Enable Setup → Vehicle → Door → Smart Liftgate in the infotainment system.
- 02
Close and lock all doors, keep the smart key with you and wait at least 15 seconds away from the detection area.
- 03
Approach the rear and stand about 20–40 in (50–100 cm) behind the vehicle for more than three seconds.
- 04
Listen for the warning chime and watch the hazard lights confirm smart-key detection.
- 05
Step clear and verify the liftgate opens after the six alert cycles.
Important limits
- The feature will not operate if a door is open or unlocked, the key is inside, or the key remains continuously near the vehicle during the 15-second arming period.
- Deactivate Smart Liftgate before an automatic car wash to prevent unintended opening.
- Keep people, cargo and overhead objects clear before the liftgate opens.
Quick checks.
- ✓If the liftgate does not arm, lock every door and move the smart key away for at least 15 seconds before approaching again.
- ✓If the alert begins unintentionally, leave the detection area with the key; the liftgate should stay closed.
- ✓If detection remains unreliable, replace a weak smart-key battery and move away from strong radio interference.
