What is the meaning of engine picture on the left side dash on 05 Buick LaCrosse?

Answer 1

That engine picture is called an engine light. It means that something needs to be checked out. How many miles do you have on your vehicle? Often times, manufactorers will set that light to go off at a certain number of miles so that you will bring your car in for a check up. Since your car is relatively new, I would guess that is probably what this is. But if you have a lot of miles on your car, there could be a problem somewhere. These days, when that light is triggered, mechanics can hook your car up to a computer that can diagnose the problem right away. This light is not something to completely ignore, but it's not likely that your car is going to quit running! The major things that I would worry about, like my oil level and brakes, have their own warning lights that come on when there's trouble in those areas. It's probably just a sensor if it's not just time for routine maintenance.
