Pontiac 2006 Vibe Owner's Manual page 198

Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that wheels are slowing down. If
one of the wheels is about to stop rolling, the computer
will separately work the brakes at each front wheel
and at both rear wheels.
ABS can change the brake pressure faster than any
driver could. The computer is programmed to make the
most of available tire and road conditions. This can
help you steer around the obstacle while braking hard.

As you brake, your computer keeps receiving updates
on wheel speed and controls braking pressure
accordingly.
If your vehicle has the vehicle stability control system, it
includes a brake assist system which provides more
powerful braking during a sudden, hard brake
application. See "Vehicle Stability Control System"
under Traction Control System (TCS) on page 4-9.
