pss sound from tires after unlock car
Just had my GLC 300 2017 3 weeks ago. Today just found, when I unlock the car, I can hear pss sound from tires, last for 10 seconds then disappear. What is this Sound? Checking tire pressure? Thanks.

I don't have air suspension and I hear the same sound too. I also hear it after turning off the engine and exiting/locking the vehicle. To me, it sounds like it's coming from underneath the car and I hear from both near the front or rear of the tires, both passenger and driver sides.

It has nothing to do with your tires - yes - there are "strange" noises that are "normal" on start-up and shut-down - hissing and the like - again has NOTHING to do with tire pressure at all... welcome to intelligent technologies

the hiss i believe is the computer starting/shutting down the sound of the fans the ticking is the hot metals in the exaust system cooling down
