Traction Off Light

The Traction Control System has been turned off; turning off StabiliTrak also turns off traction control. Wheel slip then doesn't limit acceleration unless needed to protect the driveline.

Summarized in our own words from the 2026 Chevrolet Trailblazer owner's manual (AI-assisted; every light name was matched against its cited page 2026-10-18). Your vehicle may not have every light, and other years can differ. A red warning that stays on usually means stop safely and check: your manual has the final word.
