Cadillac and GMC

This image belongs to GMC using All Wheel Steering in the Hummer, but has the wheels turned in opposite directions. The line struck through denotes that the vehicle is in CrabWalk mode (click for more and see below) or a fault in the system if CrabWalk is not active. To the driver, either may look like random lines in a stick figure.

Cadillac uses the second of the first two indicators above when all wheel steering is off. And while the vehicle can, in fact, CrabWalk, the company calls it Arrival Mode and does not use a special indicator.

Seeing one of these symbols at any time other than startup indicates a problem with the All Wheel Steering system. The fault may limit the vehicle’s speed to 50 mph or less and you will need your dealer or authorized service center to attend to it.

All Wheel Steering systems monitor a vehicle’s response to road conditions while in motion and makes small adjustment to the relative rear wheel toe settings to help enhance vehicle control and stability.

The manufacturer notes that the toe setting of the rear wheels may get stuck in a non-centered setting if the system malfunctions while driving. At this time, the system may automatically limit the speed to 50 mph or less. Handling may be difficult as well. The vehicle will be safe to drive at the reduced speed, but don’t wait to have the problem addressed.

CrabWalk mode allows the driver to turn the rear wheels at the same angle as the front wheels, which enables the vehicle to move diagonally. Normal All Wheel Steering is then unavailable. Note the image to the right and click here for more.
