Mystery Pipe??

[Steve525]

Hi Guys. Just replaced my battery and while installing the new one I noticed a small clear pipe going down thru the floor(on the side near the door!). It is not attached to anything at its top end and I am wondering should it be!
I looked all around and couldnt find anywhere to plug it into. Sunroof drain maybe? Any ideas? Thanks in advance!!

I think that may be a vent for the battery... Unless they used a sealed unit in there. If it was, there should be a port on the battery to plug it in to.

Sounds like the Gas vent for the battery...Make sure you bought a battery that has one and hook it up! :)

Until you hook it up don't let anyone smoke in your car......;)
