I have seen several posts in different areas with folks accessing 'hidden menus' in their cars ASSYS displays...I think.
Things like oil level, engine temp, transmission fluid temp, coolant temp, battery status, etc.

Could someone tell me please how to access this menu?

Thanks,

There are a number of videos on youtube. Ignition to 1st position. Seat belt red light turns off. Go to trip view on screen.Hold home button 10 sec then Ok 10 seconds and release.

I have a 2013 GLC300 SUV But haven’t been able to get it work. Don’t know why. Good luck!

Just found this on the forum. Haven’t had time to try but I wasn’t doing step 5. Maybe that’s my problem


1 – press start/stop button 1x

2 – using the left scroll pad bring up the trip/mileage display

3 – press left “Home” button for 10 seconds

4 – then immediately press left OK button for 10 seconds

5 – then press the OK button again for 1 second

6 – The workshop menu will then display

7 – using left scroll touchpad scroll to Assyst Plus

8 – You will see “For Assyst Plus – Ignition Stage 1

9 – Press the Start/Stop button again (do not touch the brake or accelerator pedal)

10 – You can then scroll through the Assyst Plus Service Interval Reset menu

Thanks very much for this. I'll give it a try. I've tried a couple of times to access these menus before and like you, I could never get it to work. Maybe this time.
