Unknown Button on Steering Wheel base
 

Hi All,
I have had my 2016 CX-3 for 3 months now and I have found a button behind and below the steering wheel that I have been unable to identify. I've pressed it but with no obvious result. I've gone through the owners manual but have not seen any mention of it. Hopefully someone here will be able to tell me what it does and when to use it.
Thanks, Ray

That's the switch for your front parking sensors.

Thanks. Makes sense.
