Okay, so earlier tonight, me and a friend were playing on the mountain in my '07 LTZ. It's been raining, so we were playing in the mud. We were spinning sideways through some grass, we skidded across some rather intense ruts that I didn't originally see... As we slid through these ruts, all of this sudden "SERVICE AIRBAG" came across my DIC... I instantly flipped out, of course... But anyway, we headed down the mountain, and we stopped and I turned the truck off. I started the truck, and the message wasn't there. I drove for an hour after-word, and it didn't flash again. Should I be worried? What could have caused this? I didn't hit anything, to my knowledge...
