How to charge battery in 2011 Polo GTI

[Hooky]

Hi,
I have a 2012 Polo GTi with the battery in the boot, under the spare and wrapped in a steel shell so inaccessible. I want to jump start it using a carpow. There appears to be a positive terminal located on the front left of the engine compartment. Is this usable to jump the car, and if yes, where should I connect the negative terminal given that there the carpow has limited reach on its cable, presumably assuming a normal two terminal battery setup?

Thanks
Hooky

I no longer have my Polo, but I think there is a large negative stud on the body in the same area isnt there?

there's a terminal in the engine bay and then you need to connect the other jumper cable to an earth point. I've had to do this to our company's 6R GTI.
