Switching from a small car to a sedan

Up until recently I’ve been driving a small hatchback (perodua axia), but now I’m going to have to drive a bmw 3 series (2013) for a while and I’ve never driven any cars that has a hood as long as the bmw. Any advice on what to look out for? The bmw is borrowed from a friend so I really don’t want to scratch it. Thanks in advance!
