Open the bonnet / hood - on the inner wing close to the bulkhead you will find a plastic box about the size of a matchbox with a red '+' on it, the top will flip up to expose a terminal. Connect your positive jump lead here and the negative lead to an engine earthing point. you should now have power to use the key button or the interior button to open the bootlid.
