Even if both hands are full, when carrying the Electronic Key, you can open and close the back door automatically by moving your foot under the rear bumper and out again. Refinements enhance fast, quiet operation, and a buzzer confirms when to move your foot out. In addition, when carrying the Electronic Key, if you press the Close & Lock switch or activate the kick sensor and walk away, a walk-away function fully closes the back door and then locks all the doors.
