User requests (one per turn):
user: I have secured my car by locking all doors and applying the parking brake. Would it be possible to start the engine so I can monitor the fuel level and battery status, ensuring smooth operation?
user: I've initiated my vehicle, and I'd greatly appreciate it if you could take a look at the tire pressures. Should any tire display a pressure below this PSI value, kindly guide me to the nearest tire service facility for a fix.
user: I think below 40 PSI would need a fix.
user: Let's share the updates on tire status. Could you tweet 'Tires checked and engine purring smoothly!' using the hashtag #RoadTrip while tagging @AutoUpdates?
user: Following the tweet, could you drop a comment saying, 'Safety first! Remember tire checks are crucial.' to emphasize tire care?
