user: I've completed the maintenance on my car and ensured the doors are unlocked. Everything, especially the tires, seems in good condition. Would you kindly assist in securing the remaining doors and initiate the engine? I want everything primed before I set off.
user: The engine should be initiated in START mode.
user: Also, let's not forget to boast a little online. Could you post an update regarding my impeccable tire condition on Twitter like 'Tire pressure is perfect!'? Don't forget to use the hashtags #CarCare and #TireHealth and be sure to give Mike a mention as well.
