I was wondering if anyone else had discovered this. In my owner's manual, I see no reference to a "tap" feature for the cruise control. It talks about holding down the accel or decel buttons to change the target speed, but I don't see anything about tapping the buttons for small changes. My Chevy truck will change up and down by 1 MPH for each tap on the accel or decel buttons. My Chrysler minivans will increase by 2 MPH for each tap on the accel, but they don't seem to have the feature on the decel side.
I tried this out of curiousity the other day and it appears to work on the Sonata as well, both up and down. I can't say for sure the amount of speed change, but it appears closer to 2 MPH than 1, but I haven't experienced carefully enough to be sure.
Anyone else find this? Is this, in fact documented somewhere in the owner's manual that I simply missed?
I was glad to see this as I've always liked this feature on my other vehicles.
