IMPORTANT THOUGHT: If a warning light being on doesn’t mean anything, why did the manufacturer put it there?
Vehicle manufacturers have added numerous warning lights on the dash- such as oil, charging, check engine light, temperature, ABS, SRS, and sensors to list a few. These lights are the vehicles “voice”. Their purpose is to warn you of a problem that exists. If a warning light is on – paying attention and getting the cause taken care of can ultimately save you money. The world is ugly from the back of a tow truck.
