After owning my 370 for a few weeks, I noticed that it would ping (spark knock) slightly when going up hills.

In the manual, 9-5, it states that "Now and then you may notice light spark knock for a short time while accelerating OR driving up hills. This is no cause for concern, because you get the greatest fuel benefit when there is light spark knock for a short time under heavy engine load."

Hope this helps anyone who had the same concerns as I did. I guess it's normal. This car is truly a different animal.
