Once you release the brake, it quickly restarts, offering two impressive benefits:
- Cuts fuel consumption, saving you money.

Troubleshooting Deactivation Issues
It's not uncommon for software glitches to cause issues with the Start/Stop system in a Porsche.
A simple reset may help clear any errors and restore normal functionality.
To do this just turn off your car, wait a moment, and then restart it.
If the issue continues, a visit to your local dealership or a certified mechanic can help.
They're equipped to diagnose and update any software-related problems, ensuring your Porsche runs smoothly.
The Start/Stop system in your Porsche can deactivate due to factors like a weak battery or engine issues.
A system like Start/Stop depends heavily on a strong battery for the power needed for repeated starts.
If your battery is old or weak, it may be time to have it tested or replaced.
Regular maintenance, such as cleaning the terminals and ensuring proper connections, can help extend its life and avoid deactivation issues.
Lastly, any issues with the engine itself could contribute to the Start/Stop mode being deactivated.
Problems with the fuel system, ignition components, or even malfunctioning sensors can impact this feature.
Watch for warning lights on your dashboard or any changes in your car's performance.
If you notice any abnormalities, it's recommended to consult a professional mechanic who can diagnose and address any engine-related issues.
To ensure that your Porsche's Start/Stop function works correctly, it is important to perform some preventive measures.
These actions will help prevent the system from deactivating and ensure a smooth driving experience:
Follow Preconditions for Auto Start-Stop
Check the Porsche Owners Manual to understand the specific requirements needed for the Auto Start/Stop function.
Ensure the feature is turned on, your seatbelt is fastened, the door is closed, and the PDK selector lever is engaged properly.
Maintain Your Battery
Some ">Porsche owners have noted that battery issues can deactivate the Start/Stop function.
Regularly inspect the battery and replace it as needed to avoid deactivation.
Keep an Eye on Temperature
Temperature plays a crucial role in the Auto Start/Stop feature. Ensure the engine temperature stays within the optimal range.
Avoid exposing your Porsche to extreme temperatures, which may cause the system to malfunction.
Consult a certified Porsche mechanic if temperature issues affect the feature.
Fasten Your Seatbelt
Some Porsches may not engage the auto Start/Stop function if the seatbelt isn't fastened as the system prioritizes safety by detecting the driver's presence.
Effect on Car's Performance
If your Porsche's Start/Stop mode isn't working, it can increase fuel use and exhaust emissions.
The Start/Stop system is designed to save fuel and reduce emissions by turning off the engine when you're not moving, like when you're waiting at a traffic light.
This might not drastically affect your car's performance, but it can make a difference in fuel consumption.
There are a few reasons why the Start/Stopmode might be deactivated. It could be due to technical problems that need further investigation.
Cold weather can also temporarily disable the system, as the engine needs to be at the right temperature to work properly.
Also, make sure your car has the right type of battery, as the wrong one can cause the Start/Stop system to malfunction.
If you don't address these issues quickly, they could cause long-term damage to your car.

Nevertheless, using Start/Stop systems can result in fuel consumption improvements of 5-8% when used correctly.
Myth 3: Start/Stop Systems Only Work for Manual Transmissions
While it is true that Start/Stop systems were initially developed for manual transmissions, they have evolved and are now compatible with automatic transmissions as well.
Modern vehicles with automatic transmissions are designed to handle start/stop systems without any issues.
