Welcome and good luck tomorrow. Make sure the dealer or previous owner goes through EVERY SINGLE FUNCTION to both prove that it works and to teach you how it works.
If it's a dealer, don't pay for it before they prove everything works and let you drive it. And, don't buy all the junk they try to push on you at closing. It's like buying a car, only worse. If you want an Extended Service Contract, don't buy it from the dealer. Buy it after from one of the direct sales places.
Be aware, no matter what the dealer calls it - it's not a "warranty." It's an insurance policy with gigantic loop holes to help the insurance company get away without have to pay any claims.
Here's a link to your brochure - it might be instructive to see what the factory brochure says about all your features and capacities:
