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. Ifyou have ever tried to steer a vehicle on wet ice, youwill 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. Whileyou are in a curve, speed is the one factor youcan control.Suppose you are steering through a sharp curve.Then you suddenly accelerate. Both controlsystems — steering and acceleration — have to do theirwork where the tires meet the road. Adding the suddenacceleration can demand too much of those places. Youcan lose control. See Traction Control System (TCS) onpage 4-9 and StabiliTrak® System on page 4-11.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.Since your vehicle is equipped with StabiliTrak®, thesystem may be active. See DIC Warnings andMessages on page 3-79 and StabiliTrak® System onpage 4-11.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.To help you steer in the direction you want to go, duringcertain sharp or sudden cornering maneuvers, gearselection is controlled. This will maximize the availabledrive wheel torque and minimize the transmissionresponse time and shift activity. During this kind ofmaneuver, the transmission shifts automaticallyas vehicle speed changes.Adding non-GM accessories can affect your vehicle’sperformance.
