Hydraulic Power Steering
If your vehicle has hydraulic power steering, it may require maintenance. See Power Steering Fluid (2.4L L4 Engine) or Power Steering Fluid (3.6L V6 Engine).
If power steering assist is lost because the engine stops or the power steering system is not functioning, the vehicle can be steered but may require increased effort. See your dealer if there is a problem.
