Almost at 12,000, anything I should DIY?

[JerseyJeff84]

I purchased my 2010 Sedan last June, and am almost at 12,000 miles. I'm estimating that I'll be around 14 or 15,000 at my 1 year anniversary.

Is there anything I should be replacing or checking at this point? I loving the fuel efficiency of the car, it's like none I've ever driven. Would it be worth replacing the fuel filter yet? How about brake pads or tires? I have the 2 year free oil change/rotation package, and they give me a checkpoint list that tells you if anything needs attention, which is better than nothing.

I'm not used to having a brand new car, as this was my first, I used to always drive 20 year old junkers(they ran like a charm though pushing 200,000!) and feel funny not doing anything but driving this Yaris :-)

Thanks for any advice.
