9-34 Driving and OperatingIf driving safely on a wet road and itbecomes necessary to slam on thebrakes and continue braking toavoid a sudden obstacle, acomputer senses that the wheelsare slowing down. If one of thewheels is about to stop rolling, thecomputer will separately work thebrakes at each wheel.ABS can change the brake pressureto each wheel, as required, fasterthan any driver could. This can helpthe driver steer around the obstaclewhile braking 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. You might hear the ABSpump or motor operating and feelthe brake pedal pulsate, but this isnormal.Braking in EmergenciesABS allows the driver to steer andbrake at the same time. In manyemergencies, steering can helpmore than even the very bestbraking.Parking BrakeSet the parking brake by holding theregular brake pedal down, thenpushing down the parking brakepedal.If the ignition is on, the brakesystem warning light will come on.See Brake System Warning Light onpage 5‑17.Notice: Driving with the parkingbrake on can overheat the brakesystem and cause prematurewear or damage to brake systemparts. Make sure that the parking
