User turns:
user: I would like to increase the amount of fuel in my car to completely full, but first I need to ascertain the present level to determine the appropriate amount to add.
user: The fuel level is not satisfactory, add it to full and then proceed to activate the engine using the 'START' function and verify the tire pressure to ensure it is in optimal condition.
user: Should I notice that my tire pressure falls below a certain psi, kindly provide me with directions to the nearest tire service center for prompt resolution.
user: Let's use 40 PSI as the threshold. Anything below that is not good.
