Magnetic Ride Control™ Vehicles with this feature automatically adjust the ride of the vehicle based on driving conditions. Magnetic Ride Control monitors the suspension system to determine the proper system response. If the controller detects a problem within the system, the DIC will display a SERVICE SUSPENSION SYS message. See DIC Warnings and Messages on page 3-79 for more information. See your dealer/retailer for service. Steering Power Steering If you lose power steering assist because the engine stops or the system is not functioning, you can steer but it will take much more effort. Speed Variable Assist Steering Your vehicle has a steering system that continuously adjusts the effort you feel when steering at all vehicle speeds. It provides ease when parking, yet a firm, solid feel at highway speeds. Limited-Slip Rear Axle Vehicles with a limited-slip rear axle can give more traction on snow, mud, ice, sand or gravel. It works like a standard axle most of the time, but when traction is low, this feature allows the drive wheel with the most traction to move the vehicle. Active Steering All-wheel-drive vehicles with the Active Steering with Enhanced StabiliTrak® option have an electronically controlled active steering system. The active steering system uses the steering actuator to automatically adjust the front road wheel turning angle based on vehicle speed and how much you turn the steering wheel. This system reduces steering effort at low speeds, improves steering feel at moderate speeds, and reduces steering sensitivity at higher speeds. All-Wheel Drive (AWD) System With this feature, engine power is sent to all four wheels at all times. This is like four-wheel drive, but there is no separate lever or switch to engage or disengage the front axle. It is fully automatic, and adjusts itself as needed for road conditions. 4-12
