Glow Plug, Battery Conditioning Indicator

Glow Plug

Glow Plug Indicator SymbolAs of 2024, this indicator has two uses. Its origin is as a Glow Plug Indicator symbol, which is found only in diesel-powered vehicles, sedans or trucks. The second is as a Battery Conditioning indicator, where an Electric Vehicle’s (EV) main battery is being conditioned prior to charging.

  • But moving on, are you sure this is your symbol?? If yes, then continue on.
  • Otherwise you can return to our main Picture Symbols page and scan again!

Diesel engines require heat in the cylinders to operate, which is supplied initially by the glow plugs when the engine is cold. This light will be illuminated when the ignition is turned on until the plugs are heated sufficiently to start the engine. The engine simply won’t start until then. The image will look like a coil or loops in amber or yellow.

In the EV, the light is only seen during battery conditioning. This process warms a cold battery to allow it to accept a charge more quickly.

Electronic Power Control Indicator Symbols

The Single Most Misunderstood Warning Indicator on Your Instrument Panel – Part I

The Tire Pressure Monitoring System

Tire Pressure Monitor SymbolHave you seen or are you seeing this light on your instrument panel?  What the heck does the symbol mean and what the heck do you do about it? It is the TPMS – Tire Pressure Monitoring System – indicator. Rare Tire Pressure Light w/ArrowsAnd it is the single most misunderstood warning indicator you will see on your instrument panel. A number of issues with today’s cars and and the people who service them come gift wrapped in this one symbol. The symbol shown to the right is a rarer version and is discussed below.

Is the Car At Fault?

We are accustomed to warning lights pointing to a fault with a system in the car. That is rarely the case here, as the light is primarily shown to inform a driver that the tire pressure or pressures in the tires—including the spare—are low and there is likely no actual fault with the vehicle! So here we will discuss the merits of the TPMS light.

Under the category of misunderstood, this light has been described by drivers variously as:

  • An exclamation point in parenthesis
  • An exclamation point in brackets
  • An exclamation point in a horseshoe
  • Flames – destined to be a classic!
  • A wishbone
  • An exclamation point in a fish bowl
  • An exclamation point in a cup
  • And, a real favorite, a candle in a glass!

Never has anyone called and said “I have an exclamation point in the cutaway of a tire” – which is exactly what it is!

Everyone from motorists to service personnel, believe it is nothing but a pain in the neck. But, in truth, it is doing its job, calling attention to the fact that the pressure in one or more of your tires is low. Addressing the issue when it comes up will save you money on tires and fuel by extending the life of your tires and by reducing rolling resistance, respectively.

The light suggests four possible scenarios:
