Powertrain
These are Drivetrain, Shift or Powertrain trouble symbols or lights, and will be red or yellow/amber if it comes up. This same symbol is also used as an Electric Shift Control System Warning Indicator. It indicates a problem has been detected generally in an automatic transmission or transaxle, or its shift system. This part of the drivetrain should be serviced as soon as possible.

- Otherwise return to our main Picture Symbols page and scan again!
This version in black and white will be seen in the vehicle’s information display. It may indicate that the transmission is overheated or there is a park lock malfunction or a major transmission malfunction. Fortunately, a text description will be seen as well.
This version is also seen in black and white. It accommodates all of the shift positions with their first letter, D, P, R, etc. If all are seen together and is found to be blinking, there is an issue with the transmission the will need service as soon as possible.
There is little that is user-serviceable in these systems, so you will need the help of your dealer or authorized service center. Some manufacturers also use these to indicate an engine problem, but the Check Engine light is generally reserved for this.
More Versions
While the exclamation point is a recurring motif in automotive instrument panel symbols, the wrench is a bit more rare. Neither is it very informative unless, a) the driver is already familiar with it or, b) the driver stops and reads the owners manual. It often indicates a transmission problem, particularly if seen in red, but it also is used for other purposes. Do consult your manual.
Do not confuse the first image with the Settings Indicator symbol on the left. It is nearly identical to the bumpy circle used when referring to the transmission, but lacks any addition in the center and is shown in gray scale. The settings indicator will most generally be seen in the separate Information Display and is the what we have become used to seeing on our phones and computers.

This is a Battery Charge Dashboard Indicator symbol. It appears as a standard AA or AAA looking battery with two lines radiating from either side, it actually indicates that a cell phone is being charged wirelessly. There is also a plus sign in the center of the battery.
It will most likely be seen in black and white and has nothing to do with charging any part of the car. So, do not confuse the symbol with either of these symbols, which also feature images of standard batteries. Click 
This is an Over the Air (OTA) Update Available Indicator 
This is a set of over the air update indicators from Lincoln. The first, with the bell, indicates that an update is ready to be installed. The second, with an exclamation point notes that the update failed or was stopped. The last one, with the check mark says that the update was successful.
This is a Seat Backrest Not Engaged Indicator 
These are Start/Stop System Function and Trouble Indicator symbols. The first picture symbol, an exclamation point in a circular arrow, is used in Canada and overseas. U.S. models use the third version in text. Despite the term “Starter System”, it does not indicate a bad starter motor, but rather a problem with the Start/Stop system. The i-stop System works in the same manner but under an odd name. These indicators may also flash when indicating they are indicating a malfunction.
The circle shaped arrow or double arrow is a standard icon for Start/Stop systems, whether it indicates a problem or simply says the system is on or off. The exclamation point, however, does indicate a problem with the system. The strike through indicates the system is off. If it flashes, there is a fault in the system.
This image with the ‘A’ inside and the exclamation point outside is used in Europe. The ‘A’ stands for Automatic Start/Stop, as its function takes place without a driver’s intervention. Note that if a problem with the system occurs, the vehicle can be operated normally. It will simply function without the fuel saving benefit of the Start/Stop and your dealer will need to be contacted.
Start/Stop systems are fuel saving systems that allow a gasoline-powered engine to shut down at typical idle times, such as at red lights, and restart with the touch of the gas pedal. If a problem occurs, the engine can be restarted using the Start/Stop button. The images to the left are more variation. The first adds the Economy abbreviation ECO inside the circling arrow to make the point that, when operating, the system adds to fuel economy. It represents an Intelligent Start/Stop System, which is no more than a naming inconsistency. The second simply notes that the Start Stop, or Auto Stop, system is active.
These two black and white indicators will ultimately be driving drivers nuts. On, off, crossed out or not? The images are being used in message centers found between the dials on instrument clusters, which makes this a departure from our attention to the red, amber, green and blue icons used on the remainder of the instrument panel.
