The ABS symbol refers to the anti-lock braking system. A brief appearance during startup can be part of a normal self-check; a light that remains on calls for attention. Note whether it appeared alone or alongside a red brake warning.
If braking feels different, the pedal feels unusually soft, or a red brake warning is also present, stop safely and arrange assistance. For an ABS concern without those symptoms, follow your owner's manual and contact 12th Street Auto Care Center in Sioux Falls about the next step.
