Calling 6 years old car "brand new" is a stretch.
I can link you to RV forum where dealing with vehicles sitting for long periods is constant issue.
You can find all kind of advices. Starting from
"Crawl out and lock the door" to
"remove the tires, remove the batteries, change all the fluids"
Since this is not US vehicle I assume you are not in this country?
Bad battery or bad tires will show right away. I wouldn't worry too much about anything else if the car was stored in dry garage. Drove on diesel older than 6 years just fine.
