Using smart liftgate
1. Setting
To activate the Smart Liftgate with Auto Open, go to Setup → Vehicle → Door → Smart Liftgate with Auto Open on the infotainment system.
2. Detect and Alert

If you are positioned in the detecting area (20~40 inches [50~100 cm] behind the vehicle) carrying a smart key, the hazard warning lights will blink and chime will sound to alert you the smart key has been detected and the liftgate will open.

After the hazard warning lights blink and the chime sounds 6 times, the smart liftgate will open.
