No automaker allows customers to permanently switch off Autostop, as was previously mentioned. Nevertheless, it can be momentarily turned off by pressing the “disable” or “off button. In addition to this choice, automobile manufacturers have compelled users to use Start-Stop since they do not provide a mechanism to completely disable this feature.

On a Volkswagen, what does auto stop mean?
We believe that being stuck in traffic is unpleasant enough without having to pay for it as well. We developed Start/Stop Technology as a fairly easy technique to assist you in saving money anytime you come to a stop because of this.
What does it do?
When you temporarily stop moving, Start/Stop virtually shuts off your engine and effortlessly turns it back on when you’re ready to move again.
How it works:
When you stop, you simply shift into neutral, let off of the clutch, and the Start/Stop technology turns off your engine. The technology just turns everything back on when you dip the clutch to start moving again. It’s more simpler if you have an automatic transmission because it automatically turns off your engine when you hit the brake and turns it back on when you press the accelerator.
How do I know if my vehicle has this feature?
- Your car features stop/start technology if the tachometer has a position marked “Auto Stop.”
- Stop/Start can be disabled using a button on some cars. You can disable Stop/Start Technology during the active key cycle if you see this button, which indicates that your car has this capability.
- If your car has Stop/Start Technology, you’ll notice that the engine shuts off when you come to a complete stop and restarts when you let off the brake.
How do I disable this feature on my vehicle?
Some cars have a button that disables Stop/Start for a single ignition cycle. If the car has a deactivation switch for Stop/Start, you can push it to disable Stop/Start. When the switch’s LED indication is not lit, Stop/Start is switched off. Every time the vehicle is started, Stop/Start is activated to help maximize the fuel economy benefit.
Are there instances when my Auto Stop may not occur and/or my Auto Start may occur?
Yes. These consist of:
- The motorist has depressed the gas pedal.
- The vehicle has not yet achieved the minimum speed between Auto Stop incidents.
- Certain driving modes may prevent Stop/Start from continuing to work at its best (e.g., 4 Lo or Track modes, if equipped)
- The vehicle’s air conditioner or heater must be operational for the cabin to be cooled or heated.
- If the functionality included a Stop/Start disable option, you had already disabled it.
- To ensure maximum vehicle performance, other factors could prevent Auto Stop from occurring or cause Auto Start to occur.
- The motorist has let off of the brake pedal.
- The duration of the Auto Stop has exceeded the allotted time.
- Out of DRIVE is selected on the transmission. Exception: In some vehicles, maintaining an Auto Stop while in PARK is permitted.
- The hood of the car is open.
- The temperature of the ambient air is not within the necessary working range.
- The transmission or engine have not warmed up enough.
- The battery of the car was recently unplugged.
- Charge up the vehicle’s battery.
Do I have to worry about the life of vehicle components due to the increased number of vehicle engine starts?
No. The vehicle’s engine starting system and engine have been specifically engineered to be robust to withstand the extra demands of the enhanced Stop/Start activity. This is similar to the battery technology.
Can I specially order a vehicle without Stop/Start Technology?
No, a vehicle model that comes standard with Stop/Start Technology cannot be ordered without it. Depending on the engine option, some car combinations may not include Stop/Start Technology.
How do I jump-start a vehicle with Stop/Start Technology?
A vehicle equipped with Stop/Start Technology can be jumpstarted in the same way as any other non-hybrid or non-electric vehicle. For information on jump-starting a vehicle, consult the owner’s manual for your specific vehicle.
Is your battery drained by auto start-stop?
Your car’s start/stop function is intended to conserve fuel and reduce pollutants. The engineering division of AAA conducted certain tests and discovered that fuel savings have reached 5%. Tests thus far have not revealed any appreciable alteration in battery or starter motor life due to additional wear and tear.
Saves fuel auto start-stop?
According to test results, automated stop-start systems enhance fuel economy by five to seven percent and reduce carbon dioxide emissions in comparison to tests done on the same vehicle with the automatic stop-start system disabled.
Why does my brand-new vehicle turn off when I stop?
The stop-start system’s theory is straightforward. To save fuel and reduce idle emissions, the engine automatically shuts off when the car is at a stop.
Is the Autostop Eliminator a warranty breaker?
Premium Subscriber If you install an Autostop Eliminator or a similar device, your warranty won’t be voided unless the dealership can demonstrate that the installation led to a problem.
What causes my auto start to stop?
Engine checking is the most frequent cause of a car starting, then quickly stopping. Your vehicle’s voltage or tachometer signals are monitored by Compustar and Arctic Start systems to determine when the vehicle has started.
How does auto start/stop function?
Under specific circumstances, the vehicle’s engine is automatically stopped and started thanks to stop/start technology. When compared to the same vehicle without Stop/Start Technology, Stop/Start Technology can help increase fuel efficiency by shutting off the engine when it’s not needed. This lowers greenhouse gas emissions.
What is Auto Start/Stop system?
Modern vehicles come equipped with automatic start/stop systems as standard equipment. While driving, this technology recognizes when the car is stationary and shuts off the engine to conserve fuel and cut pollutants. As you release the brake or depress the clutch, the engine restarts.
How to deactivate the Auto Start/Stop system on Volkswagen Audi Skoda & Seat vehicles?
1. You can push the start/stop button in your car to temporarily disable the start-stop feature, but bear in mind that it will reactivate when you start the engine again. Due to Volkswagen’s disabling of the outdated techniques, this does not function on the most recent models of the cars.
2. Cut the voltage sensor off.
The voltage sensor connector can also be unplugged from the negative terminal in order to disable Start/Stop. However, there are rare issues where the automobile is unable to check the battery level.
3. The premium version of OBDeleven PRO.

Automatic Start-Stop A technical innovation which helps the environment
The start-stop system’s basic premise is that fuel consumption and emissions can be decreased if the engine is shut off for brief intervals, such as when waiting at traffic lights. The automatic start-stop technology contributes to fuel efficiency and environmental protection in this way. CO2 emissions can be decreased by 38% with this method. The advantages to the environment and increased efficiency have sped up the adoption of automated start-systems across all vehicle classes. Automakers are also progressively integrating intelligent start-stop technologies into their lineups in response to the more strict EU restrictions on the pollutant emissions of motor vehicles.
Why does my vehicle suddenly stop when I slow down?
Transmission malfunction: The torque converter, which replaces the manual clutch in a car with an automatic transmission, is in charge of transferring power. The converter won’t function properly if the torque converter is damaged or if the transmission fluid level is low; as a result, the vehicle won’t be able to sustain power at low speeds, which results in the engine cutting out. This problem can also be brought on by a broken torque converter solenoid or TCS.
The fuel pump is in charge of moving fuel from the tank to the engine regardless of low fuel pressure, filthy or damaged fuel injectors, or a faulty fuel pump. Low fuel pressure from a damaged fuel pump can lead to an uneven stream of fuel being delivered to the engine. This doesn’t matter as much at high speeds, but at low speeds, even a little interruption in the fuel delivery might cause the engine to stall. A precise amount of fuel is sprayed out by the fuel injectors, and at the right moment, it is ignited by the spark plugs. Over time, injectors can get clogged or unclean, which causes irregular spray or no spray at all.
Bad oxygen sensor or mass flow sensor: The oxygen sensors and mass flow sensor let the vehicle adjust the air-to-fuel ratio by detecting how much oxygen is entering the fuel stream. Your vehicle won’t run as efficiently if the oxygen level is too high or too low. The car will continue to run at driving speeds, just like with low fuel pressure, but this insufficient power won’t be able to fuel the vehicle when it slows down.
Wires that are loose or rusted in the wiring harness: An ignition that fires inconsistently will cause an easily stalled engine. The vehicle can quickly lose voltage and won’t have the power it needs to remain running when you slow down if the wires don’t have a continuous, constant, and stable connection with the ignition circuit.
Idle air control actuator malfunction: During idling, the engine’s RPMs are controlled by the idle air control actuator. The electronic control unit (ECU) sends information to this actuator, letting it know what RPM to keep the engine at for a secure and smooth idle. When the actuator is broken, the engine is not sent a signal for the idle speed and shuts off.
EGR valve obstruction or restriction: Depending on whether the EGR valve is jammed open or closed, a clogged, unclean, or damaged EGR valve might cause your automobile to stall, idle incorrectly, or sputter.
