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
Enable the Hands Free Power Back Door setting and carry the physical electronic key.
- 02
Locate the lower-center kick-sensor area shown for the vehicle's bumper; tow-hitch models use a different illustrated position.
- 03
Stand approximately 19.7–23.6 in. (50–60 cm) behind the bumper within smart-access range.
- 04
Move one foot to within approximately 3.9 in. (10 cm) of the bumper without touching it, then pull it back within one second after the buzzer.
- 05
Step clear when the confirmation buzzer sounds and allow the power back door to complete its movement.
Important limits
- Keep people and objects clear; exhaust components on gasoline and hybrid variants can be hot.
- Disable the sensor around vehicle washing, towing, rear accessories or covers that could trigger it unexpectedly.
- A kick while the liftgate is moving stops it rather than immediately reversing it.
Quick checks.
- ✓Clean snow, ice, mud or dirt from the lower-center bumper and move away from plants or electrical interference.
- ✓Withdraw the foot promptly; leaving it beneath the bumper prevents operation.
- ✓If two beeps sound, repeat one clean kick; damage or strong impact around the sensor requires Lexus inspection.
