Speed Variable Assist SteeringIf your vehicle has this system, it varies the amount ofeffort required to steer the vehicle in relation to thespeed of the vehicle.The amount of steering effort required is less at slowerspeeds to make the vehicle more maneuverableand easier to park. At faster speeds, the steering effortincreases to provide a sport-like feel to the steering.This provides maximum control and stability.If your vehicle seems harder to steer than normal whenparking or driving slowly, there may be a problemwith the system. You will still have power steering, butsteering will be stiffer than normal at slow speeds.See your dealer for service.Steering TipsIt is important to take curves at a reasonable speed.A lot of the “driver lost control” accidents mentioned onthe news happen on curves. Here is why:Experienced driver or beginner, each of us is subject tothe same laws of physics when driving on curves.The traction of the tires against the road surface makesit possible for the vehicle to change its path whenyou turn the front wheels. If there is no traction, inertiawill keep the vehicle going in the same direction.If you have ever tried to steer a vehicle on wet ice,you will understand this.The traction you can get in a curve depends on thecondition of your tires and the road surface, the angle atwhich the curve is banked, and your speed. While you arein a curve, speed is the one factor you can control.Suppose you are steering through a sharp curve.Then you suddenly accelerate. Both controlsystems — steering and acceleration — have to dotheir work where the tires meet the road. Addingthe sudden acceleration can demand too much of thoseplaces. You can lose control. See Traction ControlSystem (TCS) (CTS) on page 4-9 or Traction ControlSystem (TCS) (CTS-V) on page 4-10.What should you do if this ever happens? Ease up onthe accelerator pedal, steer the vehicle the way youwant it to go, and slow down.Speed limit signs near curves warn that you shouldadjust your speed. Of course, the posted speedsare based on good weather and road conditions. Underless favorable conditions you will want to go slower.If you need to reduce your speed as you approacha curve, do it before you enter the curve, while your frontwheels are straight ahead.Try to adjust your speed so you can “drive” through thecurve. Maintain a reasonable, steady speed. Wait toaccelerate until you are out of the curve, and thenaccelerate gently into the straightaway.Adding non-GM accessories can affect your vehicle’sperformance.
