A Complete Guide to BYD First use

Your BYD EV is in the driveway. The next thirty minutes are where most owners stumble. This guide walks you through the setup in the right order, with a clear stop threshold when you should call for help instead of DIY.

First Checks and Preparations

1. Inspect the vehicle – Tire pressure should be 36–38 psi cold. Remove any shipping pucks from the suspension. Check that all windows and doors seal fully. Open the hood and make sure the 12V battery terminals are tight (a loose cable is surprisingly common after transport).

2. Check for warning signs – Look under the car for fluid leaks (coolant or gearbox oil). If you see anything dripping, do not power on the car. Contact your dealer or roadside assistance.

3. Read the quick-start card – BYD includes a laminated card in the glovebox. It shows the start procedure and the emergency release for the charging port.

Stop/escalate threshold: If the 12V battery is visibly damaged, corroded, or if you see any coolant puddle under the car, stop here. Do not attempt to start the vehicle. Call your dealer or roadside service. These issues are covered under warranty and should not be handled at home.

Initialize the Infotainment and App

Your BYD’s rotating touchscreen runs a modified Android system. Set it up before you drive.

• Connect to Wi‑Fi – Use your home network or a phone hotspot. This triggers the first OTA update (often 1–3 GB). Do this while parked.
• Create or log into your BYD account – Use the same email you’ll use for the mobile app. This enables remote control, charging history, and navigation sync.
• Set language, time zone, and region – Some units (like battery range display) lock after the first drive. Set them now.
• Pair your phone via Bluetooth – Do this after the OTA update finishes. Pairing before the update can cause dropouts.

Common mistake: Skipping the OTA update causes a “no network” error later when you try the app’s remote functions. Let it finish.

Stop/escalate threshold: If the screen stays black more than 30 seconds after pressing the start button, or if you see a persistent error message (e.g., “system failure”), don’t try to reset repeatedly. Turn the car off, wait 5 minutes, and try once more. If it still fails, contact support.

Get Your Charging Setup Right

BYDs ship at 50–60% state of charge (SOC). That’s fine for storage but not for daily use.

• Locate the charge port – Usually on the passenger-side front fender. Press the cover to open, or use the button inside the driver’s door.
• Choose your plug:
• Level 1 (120V) – The portable charger adds 3–5 miles of range per hour. Fine overnight, but slow. Use a heavy-duty outdoor-rated extension cord rated for 15 amps minimum. Never use a cheap indoor cord.
• Level 2 (240V) – A wall box adds 20–30 miles per hour. Preferred for home charging.
• DC fast charging (CCS or GB/T) – On BYD’s 800V models, 10–80% takes about 30 minutes at a 150 kW+ station.
• Set the charge limit – BYD recommends 80–90% for daily driving. Go to Settings > Charging and adjust the slider.
• Pre-condition the battery – If you plan to DC fast charge in cold weather (below 40°F), set the destination in the navigation at least 15 minutes before arriving. The car will warm the battery automatically, cutting charging time by 10–20%.

Warning: Do not use an extension cord rated for less than 15 amps with the Level 1 charger. Overheating can melt the plug.

Adjust These Settings Before Your First Drive

• Regenerative braking – Start with “Standard.” High regen lets you drive with one pedal in traffic, but it takes a few miles to get the timing right.
• Drive mode – Leave it in Normal for your first week. Eco dulls throttle response; Sport can feel jerky while you’re still learning regen.
• Tire pressure monitoring (TPMS) – After the system boots, confirm all four sensors show valid numbers. Low pressure at delivery is common; adjust to the door sticker specification.
• Side mirror auto-fold – Enable it in vehicle settings to avoid knocking mirrors in tight spots.

Common mistake: New owners brake too late because they underestimate regen deceleration. Keep extra following distance for the first 50 miles.

Pair Your Phone and Test Remote Features

The BYD mobile app (Android / iOS) handles remote climate, lock/unlock, charge scheduling, and vehicle status.

• Download the app – Check that the publisher is “BYD Auto Co., Ltd.” Names vary by region (e.g., “BYD” or “BYD EV”).
• Link your vehicle – Use the VIN (driver’s side lower windshield) or scan the QR code in the infotainment under Account.
• Test remote functions – From inside your house, try locking the doors and turning on the climate. The app should respond within 3–5 seconds.
• Schedule charging – Set a departure time so the car finishes charging just before you leave. This keeps the battery warm and improves efficiency in winter.

Troubleshooting: If the app shows “offline,” the car may have weak cellular reception. Move it to a more open spot, or connect the car to your home Wi‑Fi (if supported) to bypass the issue.

Common First-Use Mistakes and How to Avoid Them

Mistake	Why It Happens	Fix
Not unlocking the charging cable with the key fob	The port has a physical lock.	Press the unlock button on the fob before pulling the cable.
Driving with the electronic parking brake engaged	The car will move but you’ll hear grinding.	Look for the red (P) icon on the dashboard; release the brake.
Ignoring the “Battery SOC low” warning	The car will limit power and eventually stop.	Keep the battery above 20% for normal driving.

Below 10% you risk damaging the pack if left uncharged for days. |

| Using the wrong USB port for OTA updates | Some USB‑A ports are power-only. | Use the port with a data symbol (usually near the screen). |

| Forgetting to turn off the climate before leaving | The car uses the 12V battery to keep HVAC running if left in “On” mode. | Press the “OFF” button or use the app to remotely turn it off. |

FAQ

How long does the first full charge take on a BYD?

A full 0–100% charge on Level 2 (7 kW) takes about 8–10 hours for a 60 kWh battery, and 11–14 hours for a 72 kWh pack. DC fast charging from 10–80% takes roughly 30 minutes at a 150 kW station.

Do I need to break in the battery or motor?

BYD does not specify a formal break-in period, but avoid sustained full-throttle acceleration and use gentle regen for the first 500 miles to let the drivetrain bearings settle.

How do I update the infotainment software?

Go to Settings > System > System Update. Connect to Wi‑Fi. Download and install when parked. The screen may restart several times; do not interrupt the process.

What should I do if the car won’t start after delivery?

Press the brake pedal firmly, then push the start button. If the dashboard stays dark, the 12V auxiliary battery may be discharged from transport. Jump-start it using a standard 12V booster pack or call roadside assistance.

Can I use a Tesla Supercharger with my BYD?

Only if your BYD uses the NACS connector (some export models) and the Supercharger has been opened to non-Tesla vehicles. Otherwise, you’ll need a CCS-Combo (or GB/T) adapter, and even then only at compatible stations. Charging standards vary by market; verify locally.

No matter which BYD model you own—Dolphin, Atto 3 (Yuan Plus), or Seal—the first-use steps above remain the same. Take your time with the app and charging setup; the driving part will come naturally after a few miles.
