Buy the service manual if you intend to self-service the vehicle. That's where you find less obvious information like chassis lubrication points.
Sometimes you can download one from the internet, check vehicle-specific forums. A 3rd party manual (Haynes, etc) is a great supplement as the Factory manual assumes you were Factory-trained, while the consumer oriented one will walk you through some procedures in an easier to follow manner. I've spent anywhere from $100 (PT Cruiser, 8 volumes) to free for Factory Manuals. eBay will have them.
Your car may be too new to have the documentation readily available, but it will be out there soon enough so just keep looking periodically.
I buy used, so when a new vehicle comes into the fold I use a combination of a smartphone app (monitors maintenance intervals, fuel consumption, etc) and I buy a new 3-ring binder with some plastic sleeves for documentation. Receipts get stapled to a sheet of paper with any necessary note added to the sheet, placed into the plastic sleeve, and into the binder. Every change, upgrade, issue, warranty documentation, etc goes into the binder, which moves with the car when it's sold.
