BYD Atto 3 Voice Control: Best "Hi BYD" Commands Every Owner Should Know
Share
The BYD Atto 3 includes an intelligent voice assistant called BYD Assistant that responds to the wake word "Hi, BYD". It controls navigation, climate, music, phone calls, and vehicle features entirely hands-free. You can also activate it by pressing the voice button on the steering wheel or tapping the microphone icon on the touchscreen. Once awake, speak naturally and the system performs the recognized instruction.
How to Activate Voice Control
There are three ways to wake BYD Assistant on the Atto 3, verified directly from the owner's manual:
- Voice wake word: Say "Hi, BYD" clearly. The system listens immediately.
- Steering wheel button: Press the voice button briefly. The touchscreen switches to the voice recognition screen.
- Touchscreen icon: Tap the microphone icon on the infotainment display.
After wake-up, speak your command. BYD Assistant processes the instruction and confirms the action on screen. If the system doesn't understand, press the steering wheel button again to re-enter a voice command.
20 Essential "Hi BYD" Commands
Climate and Comfort
| What You Say | What Happens |
|---|---|
| "Set the temperature to 23 degrees" | A/C adjusts to 23°C |
| "Turn on the seat ventilation for the driver" | Driver seat cooling activates |
| "Turn on seat heating" | Front seat heater activates |
| "Turn on the defrost" | Windshield defrost activates |
| "Turn off the air conditioning" | A/C system switches off |
The temperature command from the owner's manual uses exact degrees. Say "Set temperature to 21 degrees" rather than "make it cooler" for the most reliable response.
Navigation
| What You Say | What Happens |
|---|---|
| "Go home" | Navigates to saved home address |
| "Navigate to [destination]" | Starts route guidance to named location |
| "Find a charging station nearby" | Searches for nearby EV chargers |
| "Find a petrol station" | Searches nearby POI results |
"Go home" requires a saved home location in navigation settings. Set this up once through the touchscreen and the voice command works every time after. For details on charger types your Atto 3 supports, see our Atto 3 connectivity and OTA guide.
Media and Entertainment
| What You Say | What Happens |
|---|---|
| "Play music" | Starts music playback from last source |
| "Next song" | Skips to next track |
| "Volume up" / "Volume down" | Adjusts media volume |
| "Start DAB+" (where available) | Switches to digital radio |
Phone Calls
| What You Say | What Happens |
|---|---|
| "Make a call" | Opens the dialling screen |
| "Call [contact name]" | Dials saved contact via Bluetooth |
| "Answer the call" | Picks up an incoming call |
| "Reject the call" | Declines an incoming call |
Phone commands require an active Bluetooth connection and synced contacts. Pair your phone through the Bluetooth Call screen before relying on voice dialling.
Vehicle Controls
| What You Say | What Happens |
|---|---|
| "Open the windows" | Windows roll down |
| "Close the windows" | Windows roll up |
| "Turn on the ambient lighting" | Interior mood lighting activates |
Vehicle control commands vary by model year and market. Some commands may require an OTA software update to unlock expanded voice capabilities. Keep your system current for the best recognition range.
Tips for Better Voice Recognition
BYD Assistant works well in a quiet cabin but can struggle with background noise. These practical tips improve recognition accuracy:
- Speak at normal volume. Shouting distorts the audio signal. A conversational tone works best.
- Use exact phrases. Say "Set the temperature to 22 degrees" rather than "a bit warmer please." The system responds better to specific, direct commands.
- Close windows first. Highway wind noise at open windows overwhelms the cabin microphone.
- Reduce passenger chatter. The system may pick up unintended words from other occupants.
- Wait for the listening prompt. After saying "Hi, BYD," pause for a beat until the screen shows the listening animation before speaking your command.
- Keep the microphone area clear. The cabin microphone is typically located near the overhead console. Avoid blocking it with accessories or sun visors.
What BYD Assistant Cannot Do?
Understanding the limits prevents frustration. As of the latest software, BYD Assistant does not support:
- Composing or sending text messages
- Reading emails aloud
- Controlling third-party apps (Spotify, WhatsApp) directly through voice. Use Apple CarPlay or Android Auto voice assistants for those.
- Toggling specific ADAS features like ACC or lane-keeping on/off. These must be changed through the touchscreen ADAS menu. See our Atto 3 ADAS features guide for the full toggle walkthrough.
- Unlocking or locking the car from inside via voice
BYD continues to expand voice capabilities through OTA updates. Commands that don't work today may be added in future software versions.
Changing the Default Voice Assistant
If you prefer Google Assistant or another voice platform over BYD Assistant, you can change the default. Navigate to Settings > Assistant and Voice > Digital Assistant App > Default Digital Assistant App on the touchscreen.
When a different assistant is set as default, the "Hi, BYD" wake word and steering wheel voice button will activate that assistant instead. To switch back, follow the same path and select BYD Assistant.

Common Mistakes Owners Make
- Saying commands before the system is listening. Wait for the on-screen prompt after "Hi, BYD" before speaking.
- Using vague language. "Make it cold" doesn't work. "Set temperature to 20 degrees" does.
- Expecting phone calls without Bluetooth. Pair your phone first. No Bluetooth connection means no voice dialling.
- Never trying voice for climate. Climate commands are the most reliable and fastest way to adjust temperature without touching the screen while driving.
- Forgetting to set a home address. "Go home" fails without a saved home location in navigation.
- Ignoring OTA updates. Each software update can improve voice recognition accuracy and add new commands.
Hidden Features Most Owners Miss
Beyond the basics, try these lesser-known voice capabilities:
- "What's the battery level?" Quick SOC check without looking at the dash.
- "Open the sunroof" (where equipped). Hands-free sunroof control.
- "Turn on rear defrost." Clears the rear window without reaching for the button.
- "Increase fan speed." Adjusts A/C fan without navigating climate menus.
The more you use BYD Assistant, the more natural it becomes. Most owners who switch from touchscreen-only to voice-first driving report feeling safer and less distracted. Your Atto 3 also supports V2L for powering devices, giving you even more ways to use the car beyond driving.
