Use only if this edition and equipment match your car. PDF page numbers may differ from the printed page labels.

01 · SMART-KEY BATTERY

Key battery exhausted?

This sequence addresses the smart-key battery, not a discharged vehicle 12V battery. Open the source illustration to locate the exact recognition area.

Unlock with the mechanical key.
Hold the smart key close to the no-power sign shown in this handbook’s illustration.
Press START/STOP and the brake pedal to start.

Have the smart-key battery replaced by a BYD authorised dealer or service provider as soon as possible. Nearby radio equipment can interfere with recognition.

02 · PROFESSIONAL RECOVERY

Show the recovery operator.

Contact a BYD authorised dealer, professional towing service or roadside-assistance organisation when the vehicle needs towing.

The handbook recommends a flatbed with all wheels off the ground. Lifting only the front or rear wheels may damage high-voltage components.

Do not arrange towing using ropes or chains alone. Read the full handbook section with the recovery operator, including securing, tow-eye conditions and any exceptions.

What this page does not cover

No generic jump-start sequence, collision reset or high-voltage instructions are provided here. Do not use another model’s procedure. If the key sequence fails, seek professional assistance rather than treating it as proof of a key-battery fault.

This page needs an internet connection. In Pocket Companion, you can deliberately download a separate keys-and-recovery reference with saved source pages for offline use. Match its edition and equipment to your car.
