Published availability and qualifications
Verified for the 2024 U.S.-market GMC HUMMER EV Pickup and SUV 2X/3X equipped with 4-Wheel Steer and CrabWalk.
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
Move to a clear area, disengage Super Cruise and stop the vehicle or reduce speed to no more than 1.2 mph.
- 02
Hold the steering wheel still and select CrabWalk in the Controls app, confirming the prompt; on vehicles with the dedicated four-wheel-steer control, use that control as shown in the vehicle.
- 03
Wait for the CrabWalk indicator and the available surround-camera view to confirm engagement.
- 04
Turn the steering wheel in the desired direction and proceed slowly while watching the vehicle corners and camera views.
- 05
Select the CrabWalk control again to return to automatic four-wheel steering before normal driving.
Important limits
- CrabWalk is a low-speed maneuvering aid, not a lane-change feature, and requires the driver to watch the entire path around the vehicle.
- Super Cruise cannot remain active with CrabWalk.
- CrabWalk operation is speed-limited; exceeding the system threshold causes it to disengage.
Quick checks.
- ✓If activation is refused, reduce speed to 1.2 mph or less and stop moving the steering wheel.
- ✓If the control remains unavailable, turn off Super Cruise and retry in a clear area.
- ✓If CrabWalk drops out, reduce speed and re-engage only after the vehicle again meets the activation conditions.
