Chevrolet Captiva Owners Manual: Antilock Brake System (ABS)

This vehicle has ABS, an advanced electronic braking system that helps prevent a braking skid.

When the vehicle begins to drive away, ABS checks itself.

A momentary motor or clicking noise might be heard while this test is going on, and it might even be noticed that the brake pedal moves a little. This is normal.

If there is a problem with ABS, this warning light stays on. See Antilock Brake System (ABS) Warning Light on page 5-18.

If driving safely on a wet road and it becomes necessary to slam on the brakes and continue braking to avoid a sudden obstacle, a computer senses that the 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 to each wheel, as required, faster than any driver could. This can help you steer around the obstacle while braking hard.

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.

Using ABS

Do not pump the brakes. Just hold the brake pedal down firmly and let ABS work. You might hear the ABS pump or motor operating and feel the brake pedal pulsate, but this is normal.

Braking in Emergencies

ABS allows you to steer and brake at the same time. In many emergencies, steering can help more than even the very best braking.

The Antilock Brake System (ABS) in Chevrolet Captiva (2006-2018) is a crucial safety feature designed to prevent wheels from locking up during braking, thereby maintaining traction and control over the vehicle. The ABS helps reduce the risk of skidding and allows the driver to steer while braking, enhancing overall safety, especially in slippery or emergency braking situations.

The ABS control module, located within the vehicle's engine compartment or near the brake system, regulates brake pressure to each wheel independently based on sensor inputs. When the ABS detects wheel lockup, it modulates brake pressure rapidly, resulting in pulsating pedal feedback. This action prevents the wheels from sliding on the road surface and enables the driver to maintain steering control.

Regular maintenance and inspection of the ABS components, including sensors, wiring harnesses, and the control module, are essential to ensure proper functioning. Any signs of ABS malfunction, such as an illuminated ABS warning light, pulsating brake pedal, or unusual braking behavior, should be promptly addressed by a qualified technician to maintain the system's integrity and safety.
