Rear-wheel Steering (Four-wheel Steering)

At low speed they turn opposite to the fronts. At high speed they turn in the same direction. It is found on some larger cars. The rear steering angle is usually only a few degrees but makes a noticeable difference in parking manoeuvres and lane changes. After suspension work or battery disconnection, the rear actuators may need calibration with a scan tool. Some systems use one central actuator, others one per wheel.

Actuators steer the rear wheels.

Faults can show warnings. Alignment procedures differ.
