To Use Anti-Lock Don't pump the brakes. Just hold the brake pedal down and let anti-lock work for you. You may feel the brakes vibrate, or you may notice some noise, but this is normal. On vehicles with four-wheel drive, your anti-lock brakes work at all times - whether you are in two-wheel drive or four-wheel drive. Braking in Emergencies Use your anti-lock braking system when you need to. With anti-lock, you can steer and brake at the same time. In many emergencies, steering can help you more than even the very best braking. Steering Power Steering If you lose power steering assist because engine stops orthe system is the not functioning, you can steer but it will take much more effort. Steering Tips Driving on Curves It's important to take curves at a reasonable speed. A lot of the "driver lost control" accidents mentioned on the news happen on curves. Here's why: Experienced driver or beginner, each of us is subject to the same laws of physics when driving on curves. The traction of the tires against the road surface makes it possible for thevehicle to change itspath when you turn the frontwheels. If there's no traction, inertiawill keep the vehicle going in the same direction. If you've ever tried to steer a vehicle on wet ice, you'll understand this. The traction you can get in a curve dependson the condition of your tires and the road surface, the angle at which the curve is banked, and your speed. While you're in a curve, speedis the one factor you can control. Suppose you're steeringthrough a sharp curve. Then suddenly you accelerate. Both control systems - steering and acceleration - have to do their work where the tires meet the road. Adding thesudden acceleration can demand toomuch of those places. You can lose control. What should you do if this ever happens? Ease on the accelerator pedal, up steer the vehicle the way you want it to go, and slow down. 4-7
