We have yet to see suede on an interior unless it has been especially ordered. The areas are usually fabric (something like buffalo or alcantara) and should be cleaned as such.
Generally speaking usea water based foam leather cleaner followed by a leather protector on the leather areas. NO need to use a 'conditioner' this is not needed.
If the areas are suede (the first) then they will need very careful maintenance as they will mark at any touch and absorb anything that is spilt on them. They will need a very good 'waterstop'protector and cleaning on a very regular basis (every week) with a nubuck cloth and napping brush. Do not use anything wet as a) this will not clean them and b) it is liable to water marking.
Caution: If you do this process to a fabric you will destroy it so make sure you check out the whole thing before you start.
Hope this helps
