BSD fault warning light
What it means
This indicates a blind-spot-detection fault, rather than confirmation that surrounding traffic has been checked.
What to do
Bring the vehicle to a BYD authorised dealer or service provider for inspection as the handbook recommends. Read accompanying messages; do not rely on this warning to judge whether a lane change is safe.
Handbook-based owner explanation, not a verbatim quotation. Check the accompanying instrument-panel message.Meaning and response handbook-checkedBYD SEALION 7 · UK handbook 07.2024 EN_V0BYD handbook · PDF p. 41
