Video tutorial

This vehicle features the ability to sync and open your garage door directly from the car without using the traditional remote. To configure this, follow the instructions below and refer to the video as well.

At the top of the vehicle's overhead console, just above the rearview mirror, there are three buttons labeled 1, 2, 3, and a house symbol. First, press and hold buttons 1 and 3 for at least 15 seconds until the red light on the house symbol starts flashing.

Then, take the garage door remote, place it near the house symbol, and press and hold both the garage door opener button on the remote and button 1 in the vehicle for 15 seconds. This will sync the vehicle with the remote, allowing you to approach the garage, and it will open automatically.

Next, locate the release lever on the underside of the rear seat, near the floor. Press this lever down while pulling the seat upwards to unlock it from the anchor pins. Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat.
