Attention: This product is designed for vehicles equipped with an Auto Start-Stop system and requires the presence of an "A OFF" button. It is not compatible with vehicles lacking this button. Installation: Turn off the vehicle’s power before installation. Remove the dashboard panel using appropriate tools, then connect the cable between the factory socket and the button socket. Setup: After installation, start the engine while depressing the brake pedal and observe for 3–6 seconds without pressing the button. The button LED will illuminate automatically. Then configure the operating mode. Mode Selection (3+X Method): 1. Disable the Start-Stop function and wait at least three seconds. 2. Press the Start-Stop switch three times consecutively (each press activates the system; wait for automatic deactivation after each). 3. Immediately after the third press and automatic deactivation, press the Start-Stop switch two, three, or four more times. Wait for the indicator to change state. This selects either Auto Shutdown Mode or Memory Mode ( factory behavior). Color: Black Material: Plastic Package Contents: 1 × Automatic Start-Stop Eliminator Cable 1 × Rocker Switch
