Hi Manu, Welcome to TAI
& i10 Family.
1. I own the Asta ( auto ) version of Grand i10 and it automatically locks up when you move away from the car for a quite a distance. Not sure if this works for Sportz version though.
2. By default, It is not designed to roll up when the lock is activated.
3. Same as above, It is not designed for all the grand i10.
I too had the same question as you, And inquired the service engineer and customer care.
The *clock* *clock* sound is not installed by default for all grandi10.
You can always get this installed by 3rd party people. But make sure you follow the guides for warranty.
Best of luck!
