How do I get my Acura RDX out of accessory mode?
In most Acura RDX models with a push‑button start, you exit accessory mode by either starting the engine or advancing to the On position using the Start/Stop button. Here’s how to do it safely and reliably.
Understanding accessory mode and why it appears
Accessory mode (ACC) powers essential electrical components like the radio and climate controls while keeping the engine off to protect the battery. You typically enter ACC by pressing the Start/Stop button without pressing the brake. If the car detects a valid key fob nearby but not in a recognized state, it can also stay in ACC until you take the next action.
Steps to exit accessory mode
Before you begin, make sure the vehicle is in Park and the key fob is inside the cabin. The following sequence applies to most recent RDX models with a push‑button start.
- Ensure the transmission is in Park and the key fob is inside the vehicle.
- To move from ACC to On (electronics powered, engine off), press the Start/Stop button once without pressing the brake. The dash and systems should become active.
- To start the engine from ACC, press the brake pedal firmly and press the Start/Stop button once. The engine should crank and the car will enter Run/Start mode.
- If nothing happens, check the key fob battery and its detection: try placing the fob closer to the Start button or in the dedicated fob spot if your model supports it, then try again.
- If the vehicle remains unresponsive, verify the 12V auxiliary battery isn’t depleted and consult the owner’s manual or your dealer for a possible system fault.
Conclusion: These steps are designed to move your RDX from ACC to a usable state—either On or actively running. If you frequently see ACC when you don’t intend to, there may be a key fob or battery issue, or a vehicle setting that needs adjustment.
Additional tips and caveats
Model year variations exist. Some trims may require a brake press in combination with the Start/Stop button to shift from ACC to On or to start the engine. If you’re unsure about your specific year, refer to the owner’s manual or contact a dealer for model‑specific instructions.
Summary
To get your Acura RDX out of accessory mode, use the Start/Stop button with or without the brake to move to On or start the engine—all while ensuring the car is in Park and the key fob is detected. If problems persist, check the fob battery and the 12V battery, or seek guidance from the manual or dealer.
