Ways to Disable Auto Start-Stop

1. Use the Dedicated Button

Most modern cars come with an auto start-stop off button. It’s often located near the gear shifter or dashboard. Press it after each engine start to disable the feature temporarily.

2. Change Driving Modes

Switching to Sport or Manual mode in many vehicles disables start-stop automatically. This varies by manufacturer.

3. Permanent Disable via Coding or Devices
