What is this button???
What is the little round covered hole near the gear shift? It's on the flat surface on the upper right side from the gear shift. You can push it in and it pops back to the surface. It's a Automatic 2003 Toyota Matrix.

Toyota Matrix was introduced in 2003. Based on the Corolla platform, the Matrix filled the hole left behind by the Corolla wagon, which was discontinued in 1997. The Matrix looks like a cross between a hatchback, a station wagon, and an SUV. The interior is spacious, with an ergonomic, well-designed dash typical of Toyotas.
The 2003 Toyota Matrix is available in three trim levels: the standard, the XR, and the XRS. The standard and the XR share the same engine with the Corolla, a 1.8-liter, four-cylinder with 130 horses. All-wheel drive knocks the horsepower down to 123, while the XRS gets 180 horses. Upgrading to the XR gets power windows, mirrors, and locks; a remote key fob; and a rear wiper, while the top-of-the-line XRS comes with 16-inch alloy wheels, anti-lock breaks, and a six-speed manual transmission. The XRS is available only in front-wheel drive. Fuel economy is about 29-34 miles per gallon.
Some drivers like the distinctive look of the 2003 Matrix, while others think it is too trendy or weird. Drivers like the roomy interior, including a generous amount of cargo space, and the fuel efficiency. Some drivers find the red-backlit gauges to be difficult to read in the daylight, and others find the car does not have enough power (with the exception of the XRS.)

The floor on the right hand side of the car is always soaking wet. could the sunroof have a leak and water gets in when it rains?
When the temperature gets below 20 degrees at night, my headlights turn on which in turn drains my battery all night. I have tried attaching a battery charger, but when it gets down below 10 degrees, that even isn't enough. I know that I can just remove the battery, but I don't really want to do that every single night during the cold winters. Any ideas as to why my car would be doing this and is there something that I can do to keeping it from doing this?
A.c. system trapping the charge somehow. I discharge the system and when I pull the hose it explodes like its fully charged. Any thoughts?
