If it was your father who bought the car, it is weird that you are behaving like this. and if your father drives it, it is a family car.
Rustam bhai has outlined everything perfectly, now you should do what you're told and then update here.
One more thing i'd like to add, if a thing is supposed to do something, it must be thrown at it, but if its not specifically build for it, then one should avoid it. a cultus is not supposed to be used like this anyway, driving a G10 on 140 is mistreatment if you ask me 
and yes, the HPs aren't gone, they are hidden some where
