If the air output is no longer cold, check your owner’s manual to ensure the correct settings are selected. Any mechanical BYD SEALION 5 DM i air conditioning repair is for an authorised BYD dealer or qualified workshop. The HVAC system interacts with the traction battery (Blade Battery) thermal management. BYD’s own procedure applies for all leak testing and compressor replacements.

Climate controls and interface

The vehicle uses a 12.8-inch rotatable touchscreen for cabin adjustments. It supports three-finger swipes for climate and fan adjustments, as well as the “Hi BYD” voice assistant. If the software interface becomes unresponsive, reading the dashboard message and restarting the system is a safe owner check. Confirm with an authorised BYD dealer / service centre if the screen remains frozen.

Refrigerant and high-voltage safety

Air-conditioning refrigerant handling requires specialised equipment. Furthermore, high-voltage components must not be opened by owners. Professional technicians must safely isolate the electrical circuits before servicing the compressor lines.
