I need to take part of the front wheel housing liner out to gain access to the windscreen washer system. I have a set of instructions:

Regarding the section at the bottom, titled "Vehicles with auxiliary heating", what does the part "you must make the cut-out" mean?
Is it perhaps a bad translation and just means that if you have this heater it will look like this, or are you literally expected to cut part of it away?
