Tata Harrier stranded as Fuel got finished - how much is reserve fuel tank in Harrier, what is the average of Harrier?

At times, we forget to get the car fuel timely and that's indeed a bad practice - as it causes inconvenience to the fellow drivers on-road and leads to congestion, the co-passengers also faces the inconvenience and it can also potentially cause an accident as well.

In my case, I was driving my Tata Harrier and it stopped right before the red light. I tried the ignition multiple times but it made a long screeching noise, quite possibly that was the fuel pump and engine noise but I was confused and worried as it was leading to some traffic jam. The nearest petrol pump was around 200meters away from the spot. My brother then rushed to the petrol pump to get some diesel for the car and I called the Tata customer care for on-road assistance too to save some time as I was wondering what was causing the noise issue. I also came outside the car to give directions to other cars so that they could timely change the lane. 

My brother brought the can of diesel and we hurriedly refueled the car and I tried the ignition. In the first attempt, it didn't work, in the second too, it didn't. I waited for a minute and then suddenly it worked. I let it like that for a bit and turned it off and again I attempted ignition to be doubly sure. It worked well so we jumped into the car, crossed the green light, and went straight to the petrol pump to get the tank fuel and to never face this crazy incident ever again. 

Learnings and lessons from the incident - 

1. Commonsense but bear in mind, never drive your car when you are low on fuel. Always have a tank full as that keeps your car in healthy condition as well as you won't face any unpleasant issues like the above one. 

2. Tata Harrier has a Fuel Tank of 50 Litres + approximately 3.5 liters of reserve capacity.

3. Always carry an empty water bottle or a can of 5 liters as finding as simple things as a water bottle when required can be extremely tough, especially at the night and when you are stuck in a random place. 

4. Not specifically related, but to escape yourself from getting cheated by petrol pumps, get your fuel tank full. It's hard for them to cheat then.
