Q: When the engine is started, warning lights show up on the dash for a moment and then go away.

Hello. This is perfectly normal. These lights come on at this time as the computer is testing them. As long as the lights are going off once the vehicle is started then there are not any problems.

Hi there. It is normal for the warning lights to come on when the key is in the ignition with the engine off. When the engine is started, the warning lights will remain on until the the issues are tested by the computer. For the engine oil light being on and when starting the engine the light will go out when the engine has made oil pressure. For the charge warning light being on, when the engine is started and the alternator begins charging, then the light will go out. The service engine soon light will come on to inform the driver that the engine is getting close to an oil change date. These are only warning lights and if the lights are staying on longer than normal, then check out the conditions of the parts related to the light to ensure that they are working properly. If you need further assistance with the warning lights, then seek out a professional, such as one from Your Mechanic, to help you.
