Does a 1999 Chevy Monte Carlo have ABS?

Not all 1999 Chevy Monte Carlos had ABS (Anti-lock Braking System). It was an available option, not standard equipment on all models. To know for sure if a specific 1999 Monte Carlo has ABS, you'd need to check the vehicle's documentation (owner's manual or window sticker if available) or look for an ABS indicator light on the dashboard.
