The Extended Parking feature in modern GM vehicles automatically shuts off the engine after a set period to reduce emissions and prevent carbon monoxide poisoning in enclosed spaces. While this feature is designed to enhance safety, there are instances where drivers may prefer to keep the engine running. Here’s a comprehensive guide to understanding and disabling the Extended Parking feature in GM vehicles.
To disable the Extended Parking feature, follow these simple steps:
Locate the Engine Start/Stop Button: Identify the engine start/stop button on the dashboard or center console.
Press and Hold the Button: Press and hold the engine start/stop button until the driver information center displays “automatic shutdown off.”
This will disable the Extended Parking feature on newer GM vehicles with the Global B electronic architecture, including models from 2020 onwards.
Reasons for Disabling Extended Parking
There are several reasons why drivers may want to disable the Extended Parking feature:
Maintaining Climate Control: Keeping the air conditioning running to cool pets or maintain a comfortable climate in the vehicle.
Waiting in Extended Lines or Surveillance: Keeping the engine running to provide comfort or power while waiting in extended lines or conducting surveillance.
Specific Vehicle Requirements: Some vehicles may require the engine to remain running for proper operation of specialized equipment or systems.
Note: GM Authority strongly advises against leaving pets alone in vehicles, regardless of the Extended Parking feature’s status.
The location of the engine start/stop button and the specific wording of the option may vary slightly depending on the GM vehicle model and year.
Some GM vehicles may not have the option to disable Extended Parking.
Disabling Extended Parking may increase fuel consumption.
It is recommended to consult with a qualified mechanic if you encounter any difficulties while performing this process.
