All Wheel Drive
These are the All Wheel Drive (AWD) Trouble Indicator symbols. These lights will be on when All-Wheel Drive is disengaged and the drive mechanism is switched to Front Wheel Drive for maintenance or if there is a problem with the system. The car can be safely operated in front wheel drive. With the exception of the red symbol below, all these symbols appear as yellow/amber.

Of course, if the vehicle is electric (EV), it gets its own indicators. The only reason to do this is that the All-Wheel Drive system is actually electric. In yellow/amber/orange, the electric AWD system is limited, and will turn off when the system is working normally.. In red, there is a malfunction. A good repair shop or your dealer will be needed.
The symbol to the left also includes a stick figure image meant to look like four wheels with the front wheels turned to the right. All these lights incorporate the AWD acronym and may include an exclamation point. Malfunctions may be indicated by the system before a real problem is obvious, but don’t waste time. Have the system checked out as soon as possible.
These symbols will flash if the vehicle is fitted with tires of differing diameters or if the air pressure in any of the tire drops dramatically. The AWD system will be unavailable, but the main front or wheel drive wheels will operate normally. The Tire Pressure Monitoring System (TPMS) light will also very likely be lit, if the vehicle is equipped with the system.
Some older vehicles use this red FWD light to indicate a problem with an All Wheel Drive system. FWD stands for Front Wheel Drive, and in this context means that the AWD has been disengaged automatically due to the problem. Only the front wheels will be available until the AWD system is repaired.

Have you seen or are you seeing this light on your instrument panel? What the heck does the 
And 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.
These are All-wheel Drive (AWD) Disabled Indicator 
If a wrench (or spanner) or exclamation point is shown alongside the caricature of a vehicle’s undercarriage, it indicates a fault and nothing else, as does the text message asking for service. Malfunctions may be indicated by the system before a real problem is obvious, but don’t waste time. See your dealer or authorized service center soon, as AWD repairs are expensive and continued use will increase the likelihood of serious damage.
These text symbols are found in an Electric Vehicle (EV) and become an excuse to add the word electric to the AWD or 4WD acronyms. The first light is yellow/amber when the electric four-wheel drive (e4WD) system is limited, and will turn off when the system is working normally. If this light is red, there is likely a malfunction. But as with all electronic systems, restart the vehicle to see if the system resets.

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…
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.
