You should top up with whatever is in. If you don't you're mixing coolants and if that's the case, read this:
"Mixing Engine Coolants
There are many myths surrounding mixing engine coolants. Some might say mixing different types of coolants can increase the effectiveness of the cooling system or perhaps even extend the life of the engine. However, the fact is that one should never mix different types of engine coolants. Each coolant is precisely manufactured with different compounds to have different effects on the engine.
Mixing different types of coolants can have different outcomes. For example, some corrosion inhibitors might lose their effectiveness when mixed with other types of antifreeze. However, there may be cases where mixing two different coolants can cause serious damage, and it's not worth it to take the risk. Before changing from one type of coolant to the other, it's best to flush out the old coolant before placing in the new type. There are various cooling flushing kits available today to make this task easier. The Environmental Protection Agency (EPA) supports recycling of coolants. They suggest that because of the lower levels of chloride, recycled coolants can actually be better for the engine. However, it's always best to consult the owner's manual of the vehicle to get recommendations on which coolants should be used for that particular vehicle."
If you don't know, safer just to top up with water until you drain it all out and refill with one type.

Yes I did use it in my 4s but as Alex has mentioned make sure you aren't mixing colours. If yours is currently pink which is typically used by most Porsche workshops then Comma G40 is the one to use but if it's green or yellow then you will need to find the matching type.

It's concentrate and should be diluted with water.
