How do I get my Honda HRV out of accessory mode?
The quick answer: park the HR‑V, apply the brake, and press the Start/Stop button to start the engine, which exits accessory mode. If you only need power to the electronics, you can cycle the ignition positions by pressing the button without the brake to move from OFF to ACC to ON.
What is accessory mode?
Accessory mode (ACC) is a low-power ignition state where the vehicle’s electrical systems—like the radio, navigation, climate controls, and interior lights—are active, but the engine is not running. On Honda HR‑Vs with a push‑button start, you move through ignition positions by pressing the Start/Stop button without pressing the brake pedal. This lets you use electronics without starting the engine. Moving to ON powers all electrical systems, and starting the engine requires the brake pedal in addition to the Start/Stop action.
Steps to exit accessory mode and start the engine
Follow these steps to move from ACC to normal operation or to start the engine. Make sure the vehicle is in Park and the parking brake is engaged for safety.
- Ensure the gear selector is in Park and apply the parking brake.
- With the brake pedal not pressed, press the Start/Stop button once to cycle from OFF to ACC.
- Press the Start/Stop button again (still with no brake) to cycle from ACC to ON, which powers all electrical systems while the engine is not running.
- To start the engine, press the brake pedal and press the Start/Stop button once more. The engine should start, and you’ll exit accessory mode.
- Once the engine is running, you can release the brake and drive as usual.
If you simply want to power the electronics without starting the engine, skip step 4 and stay in ON or ACC as needed. For starting the car later, return to step 4 when ready.
When things don’t respond: troubleshooting tips
If the HR‑V won’t exit accessory mode or won’t start the engine, check these common issues before seeking service:
- Make sure the vehicle is in Park and the parking brake is engaged.
- Ensure you’re fully depressing the brake pedal when attempting to start.
- Verify the key fob is inside the vehicle and, if the fob’s battery is weak, replace it.
- Check the 12V battery; a weak or dead battery can prevent cycling through ignition positions.
- If there’s an immobilizer or security warning, consult the owner's manual or contact roadside assistance for guidance.
In some cases, a simple reset (cycling through OFF/ACC/ON again) or a jump start may be required. If electrical issues persist, a dealer or qualified technician can diagnose problems with the ignition system or battery circuitry.
Model-year considerations
Push-button start behavior by year and trim
Most modern HR‑Vs with push-button start follow a similar OFF → ACC → ON cycle when the brake is not pressed, and the engine-start sequence requires the brake in combination with the Start/Stop button. Exact behavior can vary slightly by year, trim level, or software updates. If you’re unsure, refer to your owner’s manual for your specific model year, or check the Honda Owners Portal for precise instructions tailored to your vehicle.
Summary
Exiting accessory mode on a Honda HR‑V is straightforward: park, apply the brake, and use the Start/Stop button to cycle to ON or immediately start the engine. If you encounter trouble, verify parking, brake application, fob status, and battery health, and consult the manual or a technician if problems persist. With these steps, you’ll restore full operation and be ready to drive safely.
