For C4 For Picasso 2 2011 2012 2013 2014 2015 2016 2017 2018 Engine Ignition Start-Stop Switch Button Idle Vehicle Operating Condition Management: For vehicles that have been parked for extended periods, it can precisely control the engine start-stop to complete warm-up, regulate the vehicle's powertrain operating conditions, and maintain the stability of the vehicle's mechanical and electronic control systems. Temporary Data Clearing and Reset: Engine shutdown simultaneously triggers a temporary data clearing of the electronic control system, resetting vehicle operating parameters and preventing abnormal operating conditions caused by data accumulation. This feature automatically shuts off the engine when the vehicle comes to a temporary stop—such as at a red light or in a traffic jam—and quickly restarts it when the brake is released or the accelerator is pressed. Its purpose is to save fuel and reduce exhaust emissions. The primary function of the engine start-stop switch is to enable or disable the automatic start-stop system.
