9-64 Driving and Operating hard and hold it down, might be the wrong thing to do. The wheels can stop rolling. Once they do, the vehicle cannot respond to the driver's steering. Momentum will carry it in whatever direction it was headed when the wheels stopped rolling. That could be off the road, into the very thing the driver was trying to avoid, or into traffic. If the vehicle does not have ABS, use a squeeze braking technique. This gives maximum braking while maintaining steering control. Do this by pushing on the brake pedal with steadily increasing pressure. In an emergency, you will probably want to squeeze the brakes hard without locking the wheels. If you hear or feel the wheels sliding, ease off the brake pedal. This helps retain steering control. With ABS, it is different. In many emergencies, steering can help more than even the very best braking. As the brakes are applied, the computer keeps receiving updates on wheel speed and controls braking pressure accordingly. Remember: ABS does not change the time needed to get a foot up to the brake pedal or always decrease stopping distance. If you get too close to the vehicle in front of you, there will not be enough time to apply the brakes if that vehicle suddenly slows or stops. Always leave enough room up ahead to stop, even with ABS. Parking Brake Using ABS Do not pump the brakes. Just hold the brake pedal down firmly and let antilock work. You might feel the brakes vibrate or hear some noise, but this is normal. For vehicles with a release handle, set the parking brake by holding the regular brake pedal down, then pushing down the parking brake pedal. If the ignition is on, the brake system warning light will come on. See Brake System Warning Light on page 5‑27. A chime sounds and the warning light flashes when the parking brake is applied and the vehicle is moving at least 8 km/h (5 mph). Braking in Emergencies If the vehicle has ABS, it allows the driver to steer and brake at the same time. However, if the vehicle does not have ABS, the first reaction, to hit the brake pedal
