●
A/C system - Check the operation of
A/C units weekly.
●
Tyres - Check tyre pressure monthly.
Check tread wear and whether there
are foreign bodies embedded.
●
Windscreen defrosters - Check the
defroster vent monthly.
●
Lights - check the lighting system
once a month to con󽗉rm the state of
working.
●
Doors - check whether the boot lid
and doors can be opened and closed
normally and locked 󽗉rmly.

Lights
Headlight alignment
Headlights are aligned before vehicle
delivery. If the vehicle carries heavy load
frequently, headlights may need to be
realigned. It is recommended to have the
headlights aligned by a BYD authorised
dealer or service provider.
Fogging of lights
●
Combination lights, tail lights, and
turn signals on the side mirrors
may become foggy after heavy
rain or cleaning. This is similar to
condensation on the side window
during rain. It does not mean any
problem with your vehicle.
●
The lights are a relatively enclosed
and narrow space. The temperature
is very high when they light up
(the mask and re󽗊ector could be
burned and deformed easily), so
they need heat dissipation. There are
heat dissipation holes on the lamp
housing for convection. The greater
the temperature di󽗈erence is, the more
active the convection is. During the
convection, the moisture in the air
inevitably enters a lamp. Factors such
as exposure to sunlight, convection,
and bulb heating can cause the
moisture in the air to condense into
fog or water beads easily on the lamp
surface at low temperatures. This is
called fogging of lights.
CAUTION
●
If fog presents inside the headlight
and inside the turn signals on
side mirrors, it may be due to
high air humidity or signi󽗉cant
temperature di󽗈erence between
the vehicle and its surroundings.
In that case, turn on the headlight
or turn signal while driving. The
fog will evaporate after a short
period of driving.
●
If there is a noticeable amount
of water inside the lights, it is
recommended to drive the vehicle
to a BYD authorised dealer or
service provider for maintenance.
Sunroof Maintenance
Panoramic sunroof maintenance
1. Wipe any dust or sand from the
sunroof outer sealing strip with a wet
cloth and do not scratch it, for that
degrades its sealing performance.
2. Wipe any dust or sand on the injection
molding edge of the front glass with
a wet cloth and do not scratch the
sealing strip, for that degrades the
sealing performance;
