Question about keyless entry

[Tlager31]

With the keyless entry, is there a way to check the tire pressure, oil status, etc without starting the engine? When I press the start/stop button without my foot on the brake, I can get radio functions, but not the information display.

Press and hold the start/stop button for a few seconds and the car will go into the "on" position allowing you to access the menus.

...the Onstar app will also provide this info without even getting in the car.

Turbo is right, long press the start button while off the brake. Its the equivalent of moving the key to 2nd position in a keyed ignition.

I just press the LEFT side of the button without touching the brake. I dont hold it. It goes to the ON mode. Not sure about using the key fab for anything on the Buick. I would like to know of more features of the key fab. My Beemer could do a bunch of stuff with the fab.
