I think I see the problem....

in the "On" position I'm guessing?

beat me to it! But that's basically what I expect to see every time I accidentally hit the convertible top button at speed and it makes the same noise as my check engine light.

What is this supposed to mean?
"You Turned The Steering Wheel!? How Could You Ever Conceive Of Doing Such A Thing! You Crazy Person. Soon You Will No Longer Be Allowed To Disrupt Our Beautiful Robot Future, Bag Of Meat And Mostly Water."
I'm at work and super bored.

What person is this car marketed to? Why does it need so many idiot lights?

It's probably fine.

The cars not running. If you go to the "On" position with out starting the car, usually this is what will happen. It'll do the gauge sweep and put all the lights on. At least in the Subaru that's what it does.

I get that its in accessory mode. But you dont need that many alerts, the fact that they merely exist is whats startling

To be honest it's not really that bad. To some people it may seem excessive but it isn't really that bad if we're being honest. Some of the stuff used to be there in a gauge when analog gauges were more widely used.

I wanna say "Eco Mode" because this appears to be a Honda of some sort.

Oh, so it's some good old greenwashing then. Eco being eco-friendly rather than emphasizing "economical."

Yeeeeep.
From Honda themselves via honda.com:
Just push the big green button. In ECON mode, the engine and other energy-consuming systems are automatically configured to operate more efficiently. Need more zip? Push it again to return to regular mode.

Or, you know, it *could* be EPAS.

Electric Power Assisted Steering?
So, of the engine dies you lose steering input? That's kind of a terrible idea.

Yes, it's *Electric* Power *Assisted* steering.
If you lose electrical power, you'd lose the power assist on the rack, but can still turn the wheel. (And if you stall the engine, depending on the design, the battery can still drive the EPAS motor on its own, unlike the hydraulic systems)
Just like with the old hydraulic assist systems... (Lose the Poly-V Belt, or stall the engine, and you lose hydraulic power assist on the rack, but you can still steer).
You just no longer have to drive a hydraulic pump with the poly-v belt and have associated hydraulic lines to the steering rack. This means less power needed to drive accessories, and can increase fuel savings.

It is a current gen Honda Civic so there is that.....

There is clearly an idiot light missing. Between the ABS and CEL there is one not lit. Why didn't they put the battery light there. WHY???

So aside from lack of power density in batteries, what's stopping us from building cars with all electric A/C, power steering, etc running on entirely separate circuits from the engine in a non-hybrid vehicle?
I see no reason to still need an engine running to use those features, and it prevents some accidents because the steering doesn't become so difficult if the engine stalls.

You'd need a larger alternator to support an A/C compressor running electrically. Stepper motors (like the ones that EPAS systems generally use) are easier to run, because they only draw power if they are in motion. Technical explanation ahead...
Plus you then have to consider that changing the gas expansion (Combustion) to linear motion (Piston motion) to rotational motion (Crank rotation) to electric energy (Crank drives poly-v belt, turns alternator) to rotational motion of the compressor drive motor to linear motion of the compressor piston. This is less efficient than the crank rotation driving the compressor directly (removes the electrical conversion step, and removes the need to have an electric motor drive the A/C compressor)
A better method for dealing with A/C is what is done now with variable displacement compressors. This is because when A/C is being used, the compressor doesn't switch completely on and off, but instead the compressor displacement is adjusted to handle variance in drive speed (RPM) and A/C load.
Power Steering doesn't need to have the assist provided if there is no steering input being made. But with a hydraulic pump, the fluid is constantly pumped, and diverted back to the low-pressure side of the system, around the steering rack. In essence, this is wasting energy driving the pump, and the cycle requirement is very different from A/C.
Basically, if you can have a small motor run constantly (Think electric radiator fan), or a larger motor only run on a cycle that is infrequent (The EPAS motor only needs to draw power when the steering angle changes), then it's a good candidate for running electrically. If you have a load that requires a large motor on a closer to constant duty cycle, the inefficiency of converting the mechanical motion to electricity and then back to mechanical motion to drive an A/C compressor negates the fuel saving of only needing to drive an alternator off the crank (as you'd need a larger alternator, and larger power requirements to run an electric A/C on +12VDC)

Okay.
