A double-tap on the brake pedal (after the car is stopped) in my 2010 engages the hold feature. A bold HOLD appears on the lower left of the speedo.
Then I can take my foot off the brake and when I hit the gas, the brakes release. Great for starting on hills.
Not sure if this feature is on all the cars or just Distronic+ cars.

Armadillo888 any trick on how to allow rear passenger to just pull open door lever without having the driver to activate the release door lock?

So here's a weird one. Learned about this on my 03' E500 and tried it on the S with success.
The accelerator "learns" driving patterns and for us city drivers can get sluggish after a while. To reset:
turn key to A position battery on. Depress accelerator all the way down for 10 seconds. turn off key with pedal down. Keep car off a few minutes. Supposedly an ECU engine control unit reset. When you drive again you may notice the car is more touchy or faster out of gear.

However, I know for most cars you will eat more gas when you do this, too. Typically, when you return to the baseline map it will cause your mixture to run rich as it's safer. To lean causes detonation which damages the motor. A rich a/f mixture also leads to more carbon deposit in your motor. And we know how these cars hate carbon deposit build-up.
I don't have much experience in Mercedes, but I do in cars in general. I don't recommend resetting your ECU a lot. There's also the chance that our ECUs might use NVRAM (non-volitile random access memory) to store the maps and things it's learned. NVRAM deteriorate in cycles like a cell battery. They are fine under normal read/write operations. But if you are clearing them out a lot, you can greatly decrease the life of the chip. No one wants to buy a new ECU.

I haven't tried this yet, but you can get to the service menu. You can see all kinds of info including live battery voltage readings.
1) Turn key to position A
2) Press and hold the steering wheel buttons "OK" on the left button cluster and the phone answer button on the right button cluster.
3) The menu will pop up on the gauge screen. Use the UP/DOWN arrows on left steering wheel button cluster to navigate.

Actually, what's happening here is when you reset the ECU, you clear out the leaned fuel mappings and it returns to the safe rich a/f mixture baseline. Depending on how you drive, this could feel like better performance. But it could also be worse. It all depends on how you drive.

Actually, a reset mostly helps the TCU shifting if you've been driving the car tame for a long time or in lots of traffic.

Totally agree with the TCU side of it.
