Driving tips to the Grand Scenic, or: How do I get the thing back home?

Hello, I’m more of a guest in the Fiat department, but now I have to drive about 550 KM spontaneously on the weekend with a Grand Scenic 2nd generation preface lift. What I know is that the car is a gasoline engine, this key card and 6 gears. So now you come into play. The size of the car is ok, but I have considerable problems understanding the operation in the pictures. I also have to drive the car without someone who knows the car. I want to know the following: – The car has such a key card. What should be taken into account? If this is the keyless version: Is there a button that you have to press to lock the vehicle? If you turn off the engine also normally via the start button? – Is there an Aux-In input for these models? Where would this be hidden? – What do you do with the keys on the speedometer? In addition: Is this good to read? – I would need a cigarette lighter box to load the nav, where is it exactly? – h Do these vehicles have an alarm system? Is it susceptible? (I don’t want to go down to the car every second hour to calm it down. Have already had bad experiences) – What else to consider? I will hopefully find things like the light switch or something like that. So I thank you, for your help and hope that the questions are not too stupid. Greeting Bernd P.S.: The manual from the car itself is also not available, ergo I can’t read it there either. Unfortunately.
