Typically, major preventive maintenance services are due at 30k, 50k, 100k, mile intervals. If you still have your owners manual there should be those service intervals listed. Also, your dealership should have FREE guides that are available to you.
Look in you owner's manual for your maintenance schedule. If you don't have it I found this online. It's for a 2009, but it should be similar to yours.
