What is the purpose of the AOFF switch in the Buick Excelle?

[SanAnnie]

AOFF button stands for the Auto Start-Stop function. The Auto Start-Stop system automatically shuts off the engine when the vehicle comes to a temporary stop (such as at a red light) during driving. When it's time to move again, the system automatically restarts the engine. Additional information: Main types of engine start-stop technology: 1. Separate starter motor: This type of start-stop system uses independently designed starter and generator. The starter provides the power needed for engine startup, while the generator supplies electrical power to the starter. 2. Integrated starter-generator: The integrated starter/generator is a synchronous motor excited by permanent magnet inner rotor and single-tooth stator, which can integrate the drive unit into the hybrid powertrain system.
