A few times over the last month or so on cold mornings when I crank my 10 the DIC will say service air bag. I turn the engine off and restart and it goes away. Yesterday while we were making short trips it happened and it was not as cold. I am beginning o suspect the battery. It is the original that came in the car. It is about 9 years old. I bought my 10in October of 2010 and it had been a rental. Any thoughts?

 

 

I am going to try to get done this week
