Your Driving and the Road L- And you may evennotice that your brake pedal moves a little while this is going on. This isthe ABS system testing itself. If there's a problem with the anti-lock brake system, the anti-lock brake system warning light will stay on or flash. See Anti-lock Brake System Warning Light in the Index. Here's how anti-lock works. Let's say the road is wet. You're driving safely. Suddenly an animal jumps out in front of you. You slam on the brakes. Here's what happens with ABS. A computer senses that wheels are slowing down.If one of the wheels is about to stop rolling, the computer wil1 separately workthe brakes at each fro] nt wheel and at therear wheels. The anti-lock systemcan change the brake pressure fasterthan any driver could.*Thecomputer is programmedto make the most of availabletire and road conditions. You can steer around the obstacle while braking hard. As you brake, your computer keeps receiving updates on wheel speed and controls braking pressure accordingly. Remember: Anti-lockdoesn't change the time you need to get your foot up to the brake pedal. If you get too close to the vehicle in front of you, you won't have timeto apply your brakes that if vehicle suddenly slows or stops. Always leave enough room up ahead to stop, even though you have anti-lock brakes. To Use Anti-Lock Don't pump the brakes. Just hold the brake pedal down andlet anti-lock work for you.You may feel the system working, or you may notice some noise, but this is normal.
