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

Misunderstood Warning Indicator: Continued from Part I

This suggests four possible scenarios. The first three assume the light is not flashing:

1) All the tires are low on air (check your spare in the trunk too, if you have one). This occurs seasonally as the weather cools, and possibly several times. Solution? Check the pressures and inflate your tires properly.

2) One tire is low. This likely means a nail or other fault causing the tire to leak slowly. Checking all of the tire pressures will reveal a single tire to be low. A qualified service facility will be needed to address the problem.

3) The system needs to be reset. If you’ve recently had the tires rotated or replaced, check with your dealer about resetting the TPMS system.

4) If the light is flashing, there is a fault in the TPMS system, which your dealer or qualified service shop will have to resolve. Again in the first three cases, the light is simply illuminated, not flashing.

If you must drive before addressing the light, please do so carefully…under inflated tires are a potential hazard. Your tires are the only thing between you and the pavement. The light will go out after the proper tire pressures have been restored and after a bit of driving.

And by the way, the light will also come on if a tire blows, but the blowout will have your full attention…

So please, show this light some respect! Its doing its job, even if you see it illuminated on multiple occasions during year! Your tires need the attention.

Now if every car could tell you which tire and the exact air pressure…

Rare Tire Pressure Light w/ArrowsFinally, there are a handful of cars that use this symbol instead, so be aware! Its still a cutaway of a tire, and somewhere along the line it was decided that the exclamation point would be more easily understood.

In another article, we discuss how too many of the warning symbols shown on today’s instrument panels assume too much of today’s information-overloaded drivers and do everyone a disservice.

The International Standards Organization (ISO) establishes symbols for use on controls, indicators and telltales applying to passenger cars, light and heavy commercial vehicles and buses, to ensure identification and facilitate use.

It also indicates the colors of possible optical tell-tales, which are supposed to inform the driver of either correct operation or malfunctioning of the related devices. The American National Standards Institute also has a hand in this.

To date, the ISO has defined over 220 of these symbols, and growing! They are supposed to be identified easily by all people everywhere regardless of language and background. But all the good intentions – and not too mention a good deal of time, effort and money – has resulted in far too many symbols that mean absolutely nothing to the average driver.

Check out the videos below.

And one filling the tires.

Catalytic Converter Warning Symbol

Catalytic Converter

Catalytic Converter Warning SymbolThis is the Catalytic Converter Warning symbol. The image, which looks like flames, heat or wavy lines rising from a pipe, indicates an overheated, damaged or malfunctioning catalytic converter. The converter is vital to the proper operation of the engine, so some vehicles may reduce the engine’s power automatically. And of course, it will be very hot. The vehicle will require service immediately.

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

In newer vehicles, the sensors reading the catalytic converter trigger the Check Engine Light, one of hundreds of functions covered by the that particular warning symbol.

Exhaust Particulate Filter Warning Indicators

Exhaust Particulates

Diesel Particulate Filter symbol indicator 1Diesel Particulate Filter symbol indicator 2Diesel particle filterExhaust filter indicatorThese are variants of Exhaust Particulate Filter Warning symbol indicators. Initially used only for diesel powered vehicles, filters have been added to exhaust systems in direct injected gasoline powered vehicles as well. They are Diesel Particulate Filter (DPF) and Gasoline Particulate Filter (GPF), respectively.

  • But first, is one of these truly your symbol?? If yes, then continue on below. 
  • Otherwise return to our main Picture Symbols page and scan again!

This is an emissions control system and the filters exist to trap soot before it can be emitted to the atmosphere. Under normal driving conditions, the exhaust becomes hot enough to burn off the soot, regenerating the filter.

The light will be green during DPF of GPF regeneration. A yellow/amber light means that regeneration is needed, which is done automatically while driving. A manual regeneration procedure is generally available and involves driving at 50 mph (80 kph) long enough for the light to resolve. There are also recommendations to hold the rpm above 2,000, so a lower gear may be needed, and another that calls for intermittently releasing the accelerator for a few seconds.

More Versions

A red light indicates that the DPF requires regeneration immediately, so follow the procedure above. If the filter is not attended to, the check engine or service engine soon light will come on and engine power will be reduced. Check out some similar symbols below, which apply to diesel powered vehicles only.

Diesel Exhaust FilterDiesel Exhaust Filter 2AdBlue indicatorThe symbols to the left indicates that the Diesel Exhaust Fluid (DEF) (AdBlue) is low. The fluid creates a catalytic reaction that removes particles from the exhaust. When low, the fluid must be topped off. The fluid will need to be replaced if it is contaminated. To the right is another particle filter symbol. It may appear with an exclamation point in it indicating a failure of the system or that engine emissions are too high. Contact your dealer or authorized service center in order to properly address any failures.

All of these odd looking images are meant to indicate exhaust flow through a pipe. Lots of wavy lines, pipe openings and what could even be interpreted as flames are used.
