What this means for your car
This page is a general driving‑safety guide, not a diagnosis. The exact risk depends on your car, how it’s behaving, and whether other warning lights or symptoms are present. When in doubt, it’s always safer to park the car and arrange a tow rather than “seeing if it makes it home.”
