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. 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. When the system is turned off, the traction control warning light comes on and TRACTION CONTROL OFF appears on the DIC. If the traction control system is limiting wheel spin when the button is pressed to turn the system off, the warning light comes on and the system will turn off right away. Press the Traction Control button again to turn the system back on. The Traction Control warning light should go off. Adding non-dealer/non-retailer accessories can affect the vehicle's performance. See Accessories and Modifications on page 5-3 for more information. 4-9
