For A Reason

You hear a hiss, as the box decompresses and the explosives detach. You open the box to find 2 air canisters, a dehydrated fruit of some sort, and a key with a large backwards Z on it. You attach the canisters to your suit, and when all of the oxygen has been sucked into your suit you detach it and throw it to the side. you put the fruit into your suit's food department, and you are no longer hungry. Most of your problems are fixed, but what now? you walk around the garage and find a book on the basics of mechanics, and car parts. You recognize the vehicle on the first page as the one in the garage. you start to do some reading on the vehicle and you skim through the book picking out key words, "ZT-Certified Rover, Solar Powered, Chip Navigation Systems." you don't know what a lot of this means but you give up on trying to read because it became too confusing. You see a backwards Z on the front of the Rover and it matches the key perfectly, so you open the door and enter the cabin. Inside it is very compact and there are a lot of buttons, labeled with random letters and codes. A square disk of some sort is hanging loose from next to the steering wheel, and it is the exact same size as an ID card. You take it back to the terminal in the main room, and slide the disk in. It fits perfectly, and as you plug it in it glows a light blue color, flashes a couple times, and the map disappears from the screen, yet the disk is still glowing even after you take it out. you plug the disk back into the rover and a hologram appears on the windshield, showing the map that was on the terminal. There are 2 markers on the map, one is West, one is East. You notice all of the buttons are black accept one, a flashing red one. You decide to press it, you have no knowledge on this vehicle, so pressing the only flashing button either means something really good or bad. The garage wall folds in on itself, and the rover moves itself out of the garage. the same monotone robotic voice comes out of a speaker located in the back of the rover, "ZT-343 SOLAR WIND ROVER INITIATED : SELECT A LOCATION TO START AUTODRIVE, OR PRESS MD SWITCH TO INITIATE MANUAL DRIVING"
