Does The Idle Stop & Go (ISG) System Really Work?
This four-part article discusses how in recent years, nearly every automotive manufacturer offers a technology that saves gas and reduces exhaust emissions. Kia named their version of this technology ISG. The acronym stands for Idle Stop & Go. Gateway Kia Quakertown PA service staff department explains that the ISG system was designed to automatically shut the engine down after the vehicle has been idling for a period of time.
So anyone traveling from Allentown PA or Quakertown PA to Philadelphia is familiar with getting stuck in traffic and idling on the Blue Route. This is where the ISG technology works best. But even though the tech is innovative and well-tested, motorists still have questions because their general knowledge about repeatedly stopping and starting the engine is bad.
Thinking back over the years you sat idle in Philadelphia traffic, in line for gas, or making quick stops at your local Allentown PA or Quakertown PA Wawa, your vehicle may have sat idle for as much as 5 minutes. Also, you may have thought that starting your car used more gas than letting it sit idle, so you didn’t shut the engine down. In some instances, you may have chosen to leave the car idle because you wanted the interior the right temperature, especially when you have leather seats. Personally speaking, I installed a remote start to pre-warm the car on those cold Quakertown winter days. With all that said, the most popular questions drivers have are:
- Is the auto-stop bad for the engine or starter motor?
- Does the auto stop-start drain the battery?
- Do Stop-Start Systems Really Save Fuel?
There’s a lot of information to cover within the answers of these three questions, so let’s break them down. Looking at the first question, the subject relates to the wear on engine parts, the next addresses battery drain caused by repeated starting, and the last question examines fuel consumption and emissions control. Before jumping into the answers, owners of a Gateway Kia Quakertown PA vehicle should know the primary operation of the ISG System.
First, the technology is “ON” by default but the driver may turn the system off manually. When ON and the vehicle is in D (Drive), the ISG system detects when the engine is idle and shuts the engine down. The driver is given an alert by an AUTO STOP signal illuminated on the instrument cluster. Once the brake pedal is released or the shift lever is moved from the D (Drive) to R (Reverse) position, the system restarts the engine and the AUTO STOP indicator turns off. However, there are situations where the ISG system is automatically disabled. They are:
- The seat belt is unfastened.
- The hood or a door is opened.
- Battery condition is poor.
- The front or rear defroster is turned on.
- Engine coolant temperature is low.
- The outside ambient temperature is too high/low.
- Emission control devices activate.
- The vehicle is on a steep slope.
