1) Wiper modes: You can select if you wanna enable/disable "drop speed" when idle. Meaning if you're in 2nd speed wiper mode, it'll automatically drop it down to 1st speed (intermittent) when you come to idle. When you start to move next, it'll automatically start the speed at 2nd as you initially set it at that speed. Same goes with 3rd speed...it'll drop to 2nd speed when idle.
It's helps a lot imho, cuz when comes to traffic lights, you don't want the wiper to wipe fast. I would normally turn it off at the t.lights in my other car, but when drive the UDM, it does it by itself.
2) Ambient light: You can select soft/fast ON. Meaning, you want your interior lights to dim on/out when opening/closing door or fast on/off when operating the door.
3) Seatbelt warning: You can have it turned on to remind you of buckling your seatbelt as well as chiming.
4) Home lights: How many seconds you want to have your homelights (low beam) lights on when you switch on? It's 10: 20: 40: 60 secs of choices.
5) Units: Metric or Imperial readouts.
6) Windows: One touch UP/DOWN or press & hold operation (standard on every other practical cars).
7) Side Mirrors: To enable/disable tilting downwards while in reverse.
8) Auto lock: to enable/disable auto-lock when car reach the speed around 5kmh.
9) Selection Unlocking: To unlock driver's side door when pressed unlocked button 1st time. 2nd time press, then only all the other doors and trunk unlock. Or to disable selection unlocking, meaning everything unlocks when 1st time pressed.
10) Comfort unlocking/locking: To enable/disable windows/sunroof slide open with key.
I think there are others i may have left out but this is as much as i can remember seeing the features i have on my car using the DISPLUS once before.
