- Mohummed Ahmed bhai, I have the same experience. Front is ok, but I often hear the gearbox grinding noise quite loudly while shifting to reverse. I think that the clutch cable needs adjustment, The solution that I have come up is:
- no carpet mat on the driver's side. The carpet mat comes between the clutch and the floor.
- I disengage hand brake before shifting to reverse (in case the car was parked earlier).
I will get it checked asap myself,now that u have brought it up - thank you for that.
As for the sticker on rear defogger, as u would have read in the manual, the defogger lines get damaged only if u clean the rear window by moving the cloth vertically (like the usual practice of service stations walas). If u move the cloth across the screen horizontally, i.e. in the direction of the lines, it will be fine. There is no effect of sticker. If you want to get it removed, u can do that with a cloth moistened with petrol and it will peel off by gentle rubbing. If it is not botherinbg u, then let it be.
Happy motoring
