Chevrolet Aveo: Anti-Lock Brake System (ABS)
Your vehicle may have the Anti-Lock Brake System (ABS), an advanced electronic braking system that will help prevent a braking skid.
If your vehicle has ABS, this warning light will come on briefly when you start your vehicle.
The warning light is on the instrument panel cluster for a sedan. See Anti-Lock Brake System Warning Light. For hatchback models, the warning light is on the Secondary Information Center (SIC). See Anti-Lock Brake System Warning Light.
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 wheel.
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.
Remember: ABS does not change the time you need to get your foot up to the brake pedal or always decrease stopping distance. If you get too close to the vehicle in front of you, you will not have time to apply your brakes if that vehicle suddenly slows or stops. Always leave enough room up ahead to stop, even though you have ABS.
Do not pump the brakes. Just hold the brake pedal down firmly and let anti-lock work for you. You may feel a slight brake pedal pulsation or notice some noise, but this is normal.
