Assuming this is your first Tesla, sir down and RTFM (they are online on Tesla web site as well as built into the car). Yeah its not fun but the car is VERY different from ICE vehicles (and other EVs for that matter). Pay attention to locking and phone pairing etc (since that is an area that can be confusing). Setup the phone app and a Tesla account if you've not already done so. Dont get too adventurous on day 1 .. drive the car for a while till you have the various basic settings (mirrors, seats) and drive modes the way you like them. Get used to one-pedal driving (it will feel "wrong" at first, but like new shoes it will seem great after a few hours of driving). Try the nav system, and setup your Home and Work locations. Dont try autopilot/FSD until you are happy driving the car yourself (cause you might need to take over in a hurry).
Later on, work through the various menus to see if there are any settings you dont understand or want to tweak.
Finally, enjoy the car!!!
