As per the owner's manual and recommendations from almost everyone on forums, you don't need leather conditioner for 2014 GC because it's already coated with plastic or something as a protection so any conditioner you put there will be wasted...
a damp cloth is fine for regular weekly cleaning and a good PH balanced leather cleaner, interior cleaner or diluted APC if a damp cloth is not good enough for the job.
I'm using BlackFire Interior Cleaner
for the whole interior except carpets..
and ordered BlackFire Interior Protectnat
to try it..
