Travel Diagonally for More Maneuverability While Parking and Off-Roading
GMC
The feature allows the angle of the rear wheels to mimic the angle of the front wheels — allowing your vehicle to move more diagonally.
WHAT IS CRABWALK?
CrabWalk is a 4-Wheel Steering setting that allows the angle of the rear wheels to mimic the angle of the front wheels up to a certain angle – the max. angle depends on your vehicle. This allows you to move your vehicle diagonally.
You may want to move your vehicle diagonally to make some parking maneuvers easier or in certain off-roading situations. For example, if the rear of your vehicle is facing an obstacle on the left side and you need to turn your vehicle to the right to get around it, you might risk colliding with the obstacle in Automatic Mode.
By moving the vehicle diagonally with CrabWalk, you have the option of moving the vehicle to help avoid collisions with objects within your turning radius.
CrabWalk can only be used at speeds below 20 mph. At speeds above 20 mph, the front and rear wheels will no longer turn at the same angle. If you continue to drive above 25 mph for longer than 10 seconds, CrabWalk will disengage and return the system to Automatic 4-Wheel Steering mode.
