Please how do I turn ON the battery saver on my Ford Explorer limited 2012 model

Battery saver is just a program in the BCM. It has to do with a relay. Some things can be turned on and off threw the radio. Check or get an owners manual.

If the car starts normally in warm weather then the battery capacity will be sufficient. Cold weather decreases a battery efficiency so if the battery is just making the grade in warm weather then it will fail in cold weather. have a load test done on the battery by an accredited battery supplier. If the power requirements have been increased beyond manufacturers fitted equipment then it may be necessary to consider a larger capacity alternator. have the battery checked first as I think that is where your problem will be.

Check fuel pressure and filter. Check engine light on? Exhaust crushed or blocked? Remote start battery dying?

what kind of car is it?

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.

To confirm the problem, the basic troubleshooting is required.
