The button functions perfect in my truck -- Here is the "SIMPLE" way this feature works in my truck --
Exhaust button on steering wheel - Choose a setting
Steering wheel setting on steering wheel - Choose a setting
Truck setting - IE - NORMAL / SPORT on the dial Choose a setting
Suspension on the steering wheel Choose a setting --
NOW -- HOLD THE R BUTTON down for 3 seconds and it'll SAVE these settings -- they are saved --- now how to recall them --
Here's where the user error comes in -- the NEXT time you come into the truck -- start it up -- Click on the R Button one time - don't HOLD it -- just click on it ONCE -- it then brings up your OLD settings --but you Now click the R button ONE MORE TIME quickly again -- BAM -- the truck will automatically go into your PREVIOUS HELD settings ---
So it doesn't AUTOMATICALLY go back to your previous settings - you have to click once to bring them up, and once to engage them -- only TWO clicks and you're done. It's easier than having to go into every individual setting and RE-SET them all every time to jump in the truck...
