The console denied the process in 2ways.
1. It says only allowed in next ignition cycle. No matter what you did it will not change the mode untill next ignition cycle.

2. The console denied if the clutch has been released just after changing the mode. If you change the mode and hold the clutch for a second to disappear the "mode" from display, then everything is fine. And in this cycle of ignition you can switch the mode as many times you want. No issue till now.

The same thing i have seen in other Himalayan as well. Anyways will ask the service guy but I am sure they also dont know about this and will tell me something anonymous which leads to more confusing state .
