Bro, you can take Altis 1.6 AT anywhere in Pakistan, IN SHA ALLAH, provided, a road is there 
Not at all. Do not worry.
Just shift to lower gears, like S, B, L, D-3, D-2, etc. (whichever applies and suits the best) instead of normal "D" mode, and you are good to go uphill or down hill. While coming downhill, and on a very steep slope, just shift to the lowest gear.
