hello everyone: I purchased a 2008 HHR in mid 2013. It currently has 117K miles. The sensor ligh came on a couple of times to add air to the tires. When the correct amount was added, the sensor did not indicate to add air to the tire. Now, the sensor light indicated to "change the oil soon". I had the oil changed, but the sensor light still indicate to "change the oil soon." Can anyone tell me what I need to do so that it does not indicate to change the oil soon? Thanks

 

It's in your owners manual - see How to Reset the Engine Oil Life System.

If you do not have an owners manual most of them can be downloaded from here.

You can also find numerous discussions on your question, and the location of the owners manuals via the search tool at the top of the page here.
