Steering Power Steering If power steering assist is lost because the engine stops or the system is not functioning, the vehicle can be steered but it will take more effort. Magnetic Ride Control™ The vehicle may have Magnetic Ride Control that automatically adjusts the ride of the vehicle. The controller receives input from the system to determine the proper ride.

If this message appears, have the vehicle serviced at your dealer/retailer. Magnetic Speed Variable Assist Steering System This system continuously adjusts the effort felt when steering at all vehicle speeds. It provides ease when parking, yet a firm, solid feel at highway speeds. Electronically Controlled Air Ride Suspension Professional Vehicles may have Electronically Controlled Air Suspension. The air ride controller receives input from the system to determine the proper ride. If the controller detects a problem with the system, the DIC will display a SERVICE SUSPENSION SYS message. If this message appears, have the vehicle serviced at your dealer/retailer. Steering Tips It is important to take curves at a reasonable speed. Traction in a curve depends on the condition of the tires and the road surface, the angle at which the curve is banked, and vehicle speed. While in a curve, speed is the one factor that can be controlled. If there is a need to reduce speed, do it before entering the curve, while the front wheels are straight. Try to adjust the speed so you can drive through the curve. Maintain a reasonable, steady speed. Wait to accelerate until out of the curve, and then accelerate gently into the straightaway. 4-8
