Congratulations and Drive Safe!!
Ritz is an excellent practical car for family. Please do follow run-in period just to keep your vehicle smooth for long run.
Slot the gears in proper RPM, you should not have any problem with intermittent stopping. Better feel the engine response like smooth or dragging and make a decision to slot the gears based on high and low.
Use clutch only to change gears. The gear box is very smooth in Ritz.
BTW, what mileage have you got till now?
How is the K-series engine performing?
How is the A/c effectiveness?
