GMC Sierra Owners Manual
It is extremely dangerous to ride on the tailgate, even when the vehicle is operated at low speeds.
People riding on the tailgate can easily lose their balance and fall in response to vehicle maneuvers. Falling from a moving vehicle may result in serious injuries or death. Do not allow people to ride on the tailgate. Be sure everyone in your vehicle is in a seat and using a safety belt properly.
On vehicles with a lock on the tailgate, use the key to lock or unlock the tailgate.
Open the tailgate by lifting up on its handle while pulling the tailgate down.
To shut the tailgate, firmly push it upward until it latches.
After closing the tailgate, pull it back to be sure it latches securely.
The tailgate can be removed to allow for different loading situations.
Assistance may be needed with the removal to avoid damage to the vehicle.
On vehicles with a Rear Vision Camera, it must be disconnected before removing the tailgate. See Rear Vision Camera (RVC) on page 9‑68 for more information.
To remove the tailgate:
1. Raise the tailgate slightly, pull out and hold the cable retaining clip (A). Push the cable (C) up and off of the bolt (B). Repeat on the other side.
2. With the tailgate about halfway open, lift the right edge of the tailgate from the lower pivot.
On vehicles with the tailgate assist feature, raise the tailgate nearly all the way to the closed position prior to removing the left edge.
3. Move the tailgate to the right to release the left edge.
Reverse this procedure to reinstall the tailgate. Make sure the tailgate is secure.
