If one of the wheelsis about to stop rolling, the computerwill separately work the brakes ateach wheel.ABS can change the brake pressureto each wheel, as required, fasterthan any driver could. This can helpyou steer around the obstacle whilebraking hard.As the brakes are applied, thecomputer keeps receiving updateson wheel speed and controlsbraking pressure accordingly.Remember: ABS does not changethe time needed to get a foot up tothe brake pedal or always decreasestopping distance. If you get tooclose to the vehicle in front of you,there will not be enough time toapply the brakes if that vehiclesuddenly slows or stops. Alwaysleave enough room up ahead tostop, even with ABS.Using ABSDo not pump the brakes. Just holdthe brake pedal down firmly and letABS work.
