If you want to get rid of the vinegar smell after having the air conditioning on, when leaving the car, push the REST button on the upper center dash - it runs the blower for about 20 minutes and clears out the system.
Also, there is a hidden coin area in the front of the ash tray. Open the ash tray by pushing it in, and then pull down of the front of the ash tray - you'll see an area that you can put quarters in.
