BYD instrument cluster: owner orientation

The icon colour, accompanying words, whether it stays on and how the car behaves are all important. A changed layout after an update is different from a new fault warning.

• Stop in a safe place and photograph the complete display. • Note the time, outside temperature, battery level and what the vehicle was doing. • Check whether the message clears after the vehicle is switched off, locked and allowed to shut down normally. • Open the warning-lights section of the manual for the exact model. • Check recent settings or software changes, but do not clear evidence by repeatedly restarting the car.

• Red or stop instruction: follow the displayed instruction and obtain assistance; do not continue merely because the car still moves. • Amber: a system needs attention. Drive only if the manual and vehicle behaviour indicate it is safe, and arrange diagnosis if it persists. • Green, blue or white: this is commonly a status indicator, but confirm unfamiliar symbols in the manual.

While parked, recheck brightness, units, driver-assistance preferences and the selected information layout. If the display is blank, repeatedly reboots, loses speed information or shows braking, steering, restraint or high-voltage warnings, record a short video and seek assistance.
