What does a glow plugs idiot light look like?
I'm pretty sure the OP is referring to an icon silhouette that can be seen on the dash in the right light, but is never illuminated and not documented in the manual. I'm pretty sure I've seen it too. It's on the left or right side bar with 21-23 or 33-35 on the diagram above, I can't remember which.
To the OP, when the Voltec idea was touted, GM had said they could have diesel variants as well. Given the extra space, maybe they decided to just plop down a glow plug light for such a variant, in case they decided to make it.
Well obviously someone considered it long and hard cause this 'aint no off-the-shelf GM instrument cluster. It was put there for a reason.Honestly, I doubt a diesel Volt would need glow plugs, if such a beat existed. There's never been any indication GM considered the idea, and there are good reasons for them not to do it.
Having said that, glow plugs are needed to get the air temperature up to ignition levels when cranking a diesel at low rpms in cold weather. With the Volt's ability to spin the engine straight to operating rpm and keep it there until it runs, I doubt you'd need any help. (Most modern cars don't need the glow plugs until 30 degrees or so even now.)
The overall instrument cluster might not be off the shelf but many of the parts used in it are likely off the shelf. I'm going to put my money on that the lights on the left and right side of the display are shared with some other vehicle that has a diesel engine (like the Cruze).Well obviously someone considered it long and hard cause this 'aint no off-the-shelf GM instrument cluster.

"Your electrical system is malfunctioning, prompt service is required." "Your oil pressure is low, prompt service is required."....To put future upgrade capability in automotive electronics is not that unusual. Dating myself, my college car was 1986 Chrysler Laser, it had a digital instrument panel and had a voice warning feature. Any of you guys remember those? Anyway, it would say things like "your door is ajar". Being 18 I thought it was cool as hell at first, but over time it became annoying. The last draw was one day when I got in it and it told me the "driver side rear door was ajar" -- the car was a 2-door. Had "Betty" turned off for good shortly after that.
And I would promptly reply "A door isn't a jar, a door's a door!!!"To put future upgrade capability in automotive electronics is not that unusual.
