Make sure to remind them to use 5w30 oil.
Make sure that your tires are rotated.
also, your service (in the US.) should be free.
If possible, get the tech's checklist of items that were inspected and/or performed.
you might be able to ask them to check the tire tread depth on each of your tires and have them write that up on your report. You might also be able to get a free alignment check/resetting (depending on dealer, and also any reports about highway drifting).
Make certain that your tire pressures are correct when you leave. The manual states 35 psi front, 33 psi rear, although running at a higher pressure (around 40 psi, provided that you have the OEM Bridgestone Potenza RE92 XL tires (max 50 psi)) is usually preferred for better tire life. After leaving my first oil change, all of my tire pressures had been set to 32 psi all around, from the 42/40 (or thereabouts) that I usually run at. After leaving my second oil change, my tires were at 40 front/42 rear (the front tires should have a higher psi, and my tires were just rotated but the pressures not readjusted).
