My understanding of the transmission and engine systems are that they are in a "learning mode" during the first 1500 miles/2450 kilometers. I assume the GM engineering team have set some general parameters to help protect the car from abuse in it's early days, but it's still possible to do some harm. You'll see your tach's red lines change when you hit 500 miles (sorry, I'm too old for metric), and it's sort of a "OK, you can start exploring what this car can do" thing, but don't go really crazy until 1500 miles. If you have the 2024 OM downloaded, search "break-in" to find out the recommended things to avoid during the early days. Hard acceleration, braking, and cornering, being 3 of the main ones. This also lets the physical parts get used to each other, before the "spiritied driving" can formally begin. Then all Hell breaks loose. Believe me, it's well worth the wait.

[QUOTE="MKC8, post: 340054, member: 8934"] My understanding of the transmission and engine systems are that they are in a "learning mode" during the first 1500 miles/2450 kilometers. I assume the GM engineering team have set some general parameters to help protect the car from abuse in it's early days, but it's still possible to do some harm.
