D&D 5E How do you adapt an elemental of CR5 to any lower CR quickly when a player summons one ?

I have a question about the spells than can have players summon creatures. If I have player summon an elemental, the spell description says it can, for example, have one elemental of CR 2 appear. But when I check the monster's guide, the elementals visible there (one for each element) are CR 5. How do you adapt an elemental of CR5 to any lower CR quickly when a player summons one ? (I currently own the the Player's guide and Monster's guide. Master's guide ordered but not yet available in France)

There are other elementals in the monster manual of lower CR (the spell references the subtype elemental, not the group of creatures named elementals). Mephits, magmins, and firesnakes can be conjured.

Of course once you do receive your DMG you can use the monster construction rules to build lower CR versions of the classic elementals as you see fit.

Thank for your answer. As I am reading the Player's handbook, I am also generating a few tables and monsters so when a player uses a spell or I need something to be available quickly, I got it under hand, like 5 examples of a monster than can be summoned for example, so I don't need to roll dice, and got I ready.

I checked Amazon, where I ordered my books, and I dont think I'll have the DMG in hands before 25 or so
