BYD SEALION 7 software update 3.3.0: owner guide
Step by step: prepare for an offered update
• Confirm that the notification names SEALION 7 and record the complete version currently shown by the vehicle. • Park safely, select P and allow enough time for the vehicle to remain unavailable. • Read every battery, connectivity, locking and timing requirement shown on your own centre display. • Start or schedule the installation only through the vehicle's update screen when you will not need the car. • Do not drive, charge, disconnect the 12V supply or interrupt installation unless the vehicle explicitly instructs you to. Menu wording varies. Use our BYD OTA update guide alongside the official manual for your vehicle. Never install an unofficial software package to force this version.

SEALION 7 completely unresponsive: safe 12V checks
Record the pattern
• Try the normal smart key and spare key once, away from other electronics. • Note whether any interior light, exterior light, lock sound, screen, charging-port light or warning responds. • Check whether the vehicle is connected to a charger and record any message shown by the charge point. • Think back to a recent OTA installation, long parking period, accessory use or warning, but do not assume it proves the cause.

Why can the full-charge estimate change?
