Odd sound when letting off brakes

[smcnally]

I just got my 09 Passion last night and love it. One thing I've noticed (and was wondering if it is normal) is that when I'm at a stop and let off the brakes I hear what sounds like air being released. Is that a normal sound for this car? I was thinking that maybe the clutch is pneumatically actuated and that was all I was hearing. I only really notice it if I'm at a drive-thru where the sound reflects off of a building.

That's the sound of the hill holder function releasing...

Excellent! Thanks for the info

You got the compressed air brake system option?

Is this your smart? This is closest thing to a semi I could find in a smart and semi's have air brakes.
