Light on dashboard with car and wrench lit up

This would be your engine check light. First off you need to check all your fluid levels. This includes windshield wiper fluid, brake fluid, oil, transmission fluid if it is an automatic. Remember that the transmission fluid on an auotmatic measuers in pints on the dip stick and not quarts even though it comes in quart bottles. The car must be in neutral and riunning while checking the fluid. Be sure you put the emergency brake on too just in case it ever slipped into gear. Things happen. Check radiator water level and power steering fluid.
With this light on it the computer will drop the engine into safe mode and have less power. If after all the fluids are filled and it is still on then it will be time to take it in and have the mechanic check the computer to tell you what needs repaired. This may cost 75 bucks or more but there is a thousand things that can turn that light on. Unless you can tell me if the car was acting up in any other features prior to the light coming on. If so then let me know and I will try to help you, Good Luck, The Raz
