Presumably your B5 is a Diesel mild hybrid? The minimum and maximum marks on the sensus screen denote the 'topping up range' not the sump level. Volvo have instructed their service dealers to only fill halfway between the two marks to prevent sump/oil overfill after aborted DPF regeneration cycles.
The car will alert you to top up well before any critical low level is reached, similarly it will alert you of an 'overfill' if the oil level rises as above.
Mention to your dealer that you have concerns about making a long journey whilst towing, they are best placed to advise you of the situation, I would!
