    • The "Full Accessory Power Active" message typically appears on your Ford Edge's instrument cluster when the ignition is in the accessory mode, meaning the engine is not running but the car's electronics (like the radio and windows) are operational.

      Here are the steps to start your Ford Edge when you see this message:

      1. Locate the start/stop button on your vehicle.

      2. Make sure the smart key is inside the vehicle.

      3. With your foot on the brake, press the start/stop button once. The message should disappear and the car should start.

      If your vehicle doesn't start, there might be an issue with your key fob's battery or a problem with the ignition system. Here are some troubleshooting steps:

      1. Replace your key fob battery: Your key fob might not be detected by the car if its battery is low.

      2. Try your spare key: If you have a spare key, try using it to start the car.

      3. Use the key fob's emergency start method: There's a built-in way to start the car if the key fob's battery is dead. Refer to your owner's manual for the procedure, but typically, you need to place the key fob in a designated spot (like in the center console or against the start/stop button) and then try to start the car.

      4. Check the car battery: If your car's battery is dead or low, the car might not start.

      5. Seek professional help: If none of these steps work, it's best to call roadside assistance or a mechanic to inspect the vehicle.

      Remember to always consult your vehicle's manual for exact procedures and troubleshooting steps.
