Kiefer Kia offers a number of tips for what to do when a warning light shows up on your vehicle's dashboard.
Those special indicator lights shouldn't be ignored. For instance, a light that looks like an oil can indicates a potential drop in oil pressure. An oil change will often take care of the problem; otherwise, there may be a significant engine issue that needs to be caught as soon as possible. Of course, it's also possible that a new sensor is needed. A repair technician can figure out the exact nature of the issue at hand.
A low fuel light means your vehicle is nearly out of gas. Read the owner's manual to determine at what point the light turns on; typically, there are only a couple of gallons -- or less -- left in the tank when the light illuminates. Refuel as soon as possible.
The check engine light is perhaps the most enigmatic in that it could mean an array of things. A computer diagnostic test can determine why the light illuminated. It's best to take the car in to a repair shop to run tests and ultimately reset the light once the problem is solved.
