How to Emergency Start a BYD S6?
3 Answers
Here are the methods to emergency start a BYD S6: 1. When the entire vehicle has no power: You need to jump-start the battery. Contact a rescue vehicle, then connect the jumper cables to temporarily charge the battery from the rescue vehicle to start the engine. 2. When the smart key is out of power: You can use the mechanical key inside the smart key to start the car. 3. Forced start method: The vehicle will automatically cut off power within 10 minutes after turning off the engine to prevent excessive battery drain, which may cause difficulty in starting the engine. Alternatively, press the start button directly without stepping on the brake pedal to turn on some of the vehicle's power. Press the button twice in succession to turn on all power in the vehicle, and the car will enter the self-check procedure, allowing you to start it.
Last time my BYD S6 suddenly wouldn't start, which gave me a scare. After checking, I found out it was because the remote key battery was dead. Luckily, I had a spare mechanical key. I felt around and found the small hole under the door handle, inserted the mechanical key, turned it to unlock the door, and got in. Then I sat in the driver's seat and tried inserting it into the ignition switch position. If there's no response, it might be an issue with the vehicle's main battery. In an emergency, the most reliable method is jump-starting: find another car, park it steadily and turn off the engine, use the red jumper cable clamp to connect to the positive terminal of the BYD's battery, and the other black clamp first to the other car's negative terminal, then connect it to a metal part of the BYD's body to avoid sparks when starting. After the car starts, don't drive away immediately; let it idle for a few minutes to charge. For prevention, change the key battery every three months and check the main battery's health every six months.
I have experience to share about emergency starting a BYD S6. If the key fob fails, don't panic—first check inside the car to see if the remote's battery is dead. Replacing it with a spare should solve the issue. If the car still won't start, it's likely due to a dead car battery. Prepare a set of jumper cables and ask a friend for help with their car. Open the hoods of both cars, park them parallel, and turn off the engines. Attach the red clamp of the jumper cables to the positive terminal of the other car and the black clamp to the negative terminal. Then, connect the other end's red clamp to the BYD's positive terminal and the black clamp to an unpainted metal part of the BYD's engine bay. Have your friend start their car, wait a moment, and then try starting the BYD. Once successfully started, promptly visit a professional shop to check the battery. Regularly monitor the key fob's indicator light—replace the battery when it flashes slowly to avoid future trouble.
