Based on my experience couple of times i would recommend following:
Do check engine oil level once or twice + put coolant + do keep sufficient pertrol if you have CNG + Do not overlook any extra sound/noise + keep tyre pressures slightly lower than normal + you did not mention model; if older ask your mechanic to check all nut/bolts directly related to running of car + if your tuning is due, plz get it done it will save your overall travel cost
NO EXTRA/UNNECESSARY STOPS IN BETWEEN
START VERY EARLY MORNING, RATHER TRY TO BE NEAR HYDERABAD CLOSE TO SUNRISE
Keep sufficient water and eatables in the car
Don't drive rash; it does not buy you any extra time
and I rest my case for other PW fellows to add on
