MANEUVER YOUR SIERRA EV WITH 4-WHEEL STEER


Available 4-Wheel Steer syncs your front and rear wheels to offer greater vehicle maneuverability while parking at low speeds and on tight off-road trails. The system increases low-speed agility and allows the driver to achieve a tighter turn circle. 4-Wheel Steer is also designed to help improve vehicle stability when towing a trailer.

This feature also includes CrabWalk, a 4-Wheel Steer setting that allows the rear wheels to turn at the same angle as the front wheels — allowing the vehicle to move diagonally.

The 4-Wheel Steer feature has three modes: Automatic, CrabWalk and Off.


  • 4-Wheel Steer is engaged on your vehicle in Automatic Mode by default.
  • In Automatic Mode, at speeds below about 25 mph, your vehicle’s rear tires will turn in the opposite direction of the front tires for maximum maneuverability. This is referred to in your Owner’s Manual as “out-of-phase” turning. It lets you achieve a tighter turn radius.

a. At speeds over 25 mph, the rear wheels steer in the same direction as the front wheels to improve handling and stability. This is referred to as “in-phase” turning.

  • To turn Rear Steering off, tap the Rear Steering button in the Controls app. Tap it again to turn it back on. 
  • Some vehicles with 4-Wheel Steer also have CrabWalk, which lets the rear wheels turn at the same angle as the front wheels at low vehicle speeds up to 25 mph. This lets you move the vehicle more diagonally, which provides greater maneuverability when you’re off-roading or parking.

a. To turn CrabWalk on, make sure your vehicle is either stopped or at a crawl speed (slower than 1.2 mph) and your steering wheel is still.
b. Open the Controls app on your infotainment screen, then, tap the Rear Steering button in the Controls app. Finally, tap the CrabWalk button.
c. You can turn CrabWalk off by either tapping the crab icon you see on the left side of your screen or by tapping the CrabWalk button again through the Controls app.
