Using the Injen X - Pedal Pro Black Edition is super easy. First, make sure your vehicle is turned off. Locate the accelerator pedal sensor and plug in the throttle controller. It's a plug - and - play design, so no complex wiring is needed. After installation, turn on your vehicle. You can then switch between the Sport Mode, ECO Mode, and Launch Control/Drag Race Mode according to your driving needs. When driving on mountain roads or for a more exciting experience, use the 9 - level Sport Mode. In the city, switch to the 7 - level ECO Mode to save fuel. For quick acceleration, use the Launch Control/Drag Race Mode. As for maintenance, keep the black anodized aluminum housing clean. You can use a soft cloth to wipe it. Avoid exposing it to extreme temperatures and moisture. If you have any issues, refer to the user manual or contact customer service. Also, remember that while it is warranty - friendly, make sure to follow all the warranty terms and conditions.
