I noticed that HI reading after my first oil change at the dealership. They put in 8 quarts, but that might be a little too much. You can check the oil level two ways. By the dipstick, of course, but the other way is on the dashboard. After the car has been turned off for at least 5 minutes, turn the key to the ON position - the position just before the START position. Wait about 5 seconds and you'll see the oil level icon. Press the left **** twice. You'll see OK, LOW or HI. It's just an easy way to check the oil without lifting the hood. Go back to the dealer and have them check the oil both ways (you'll have to wait 5 minutes, of course). If it's high, ask them if they want to document this problem or drain a half quart of oil. They'll probably tell you that it won't hurt the engine and they'll document it. That's what I did. At my second oil change I reminded them of this and they did it right - either let it drain alot longer, or add a little less oil. Whatever, my car is running fine.
