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
Park on level ground, remove any trailer or hitch obstruction and verify the area behind the truck is clear.
- 02
Open the primary outer gate using its release button.
- 03
Release and lower the inner gate after the outer gate is fully down.
- 04
Unlatch the inner panel and fold it completely down to form the full-width step.
- 05
Deploy and lock the available cargo-box assist handle before climbing, then keep the combined person-and-cargo load within 375 pounds.
Important limits
- The 375-pound rating includes both the user and any cargo being carried.
- Do not lower the inner gate onto a hitch ball, trailer or other obstruction; GMC warns this can damage the tailgate.
- Use the step only when the vehicle is parked on stable ground.
Quick checks.
- ✓If the inner gate is already down and the outer gate will not release, hold the outer-gate button for two to three seconds on the side-by-side-button design.
- ✓If both gates do not open together, use the correct sequence for the truck: outer then quickly inner, whether the buttons are side-by-side or stacked.
- ✓If a gate binds, stop and check for hitch hardware, shifted cargo or ice before applying more force.
