Caution: 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.

Use the Remote Keyless Entry (RKE) transmitter or power door lock switch to lock and unlock the tailgate.

Open the tailgate by lifting up on its handle while pulling the tailgate toward you.

To shut the tailgate, push it firmly upward until it latches. Push and pull on the tailgate to be sure it is latched securely.
