I45 Hyundai Cruise Control and Petrol Tank Hire Car

So my car is a bit old and I am planning a trip to Lakes Entrance. My partner needs a wheelchair and other equipment so I wanted to make sure it all fitted in the hire car so I did a trial run this weekend. Here is the Hyundai i45, more economical on fuel then my car which is old. Traralgon and back plus a bit of driving around. (403km $41)

Cruise control was easy to use once I figured out hot to set it, hard to read the buttons in the dark. I had to park up the car and wonder around the car figuring out how to open the petrol flap, i eventually popped the boot and saw a chord on the left panel, I wish someone had told me! I now know there is a button UNDER the arm rest So now you know. When you pick up a car in the dark there is no time to run around making sure you know where things are, you assume you will be able to find them. Two other people looked for the petrol cap flap opener... without success.
