Start/Stop System Function and Trouble Indicators

Start/Stop System

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.

More Versions

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.

The image on the left says the engine is ready to restart. The image on the right indicates the Start/Stop system is turned off. In this case, a button or switch somewhere on the dashboard with a similar symbol can be found and pushed to reactivate the system.

Remember that only proper service and repair procedures will ensure the safe and reliable operation of your car. In addition, proper safety procedures and precautions, such as the  use of safety goggles, the right tools and the equipment should be followed at all times to eliminate the possibility of personal injury or improper service which could damage the vehicle or compromise its safety.

Technology is always changing and what is current and accurate today may be literally out-of-date and inaccurate tomorrow. And when it comes to the current state of flux in the auto industry, nothing is more true.
