paint and decorating components;
If there are chips and scratches in
the paint, please repair it immediately
in order to prevent corrosion from
staring at this location. If the chips and
scratches have gone though the bare
metal surface, please contact the BYD
authorized dealer for repair.
Check the interior of your F3DM; Water
and dirt will accumulate beneath the
floor mats and could cause corrosion.
Please check the underside of the
floor mats occasionally to make sure
the area is dry. Please pay particular
attention when transporting chemicals,
cleansers, fertilizer, salt and similar
materials which should be transported
in proper containers. In case of any
spillage or leakage, please clean and
dry the affected area immediately.
Use mudguard. When driving in salted
roads or roads with gravel, mudguard

would protect your vehicle from mud.
The larger the size of mudguard and
lower clearance altitude are the better
protection your vehicle will get. Small
mudguard for wheel cover is optional
for BYD F3DM, installation of which is
available at BYD authorized dealer.
Park the vehicle in a well ventilated
garage or a roofed place rather than
in a damp or poorly ventilated place.
If you wash your car in the garage
or drive on a wet or snowy road, the
garage may get damp and it will cause
corrosion. Even though the garage
is dry, the car will also get damp and
suffer corrosion if the ventilation is
poor.

Tips on Maintenance of

Vehicle Paint

Please pay attention to the following
points in using and maintaining of the

car:
( 1 ) C l e a n t h e d i r t o n t h e c a r
b e f o r e , d u r i n g a n d a f t e r u s i n g
your vehicle, which can minimize
a d h e r e d d i r t b y e l e c t r o s t a t i c .
(2) Wash your F3DM timely after
rain. The rain stain on the car body
will shrink in size after rain, which
means acid materials in the rain will
concentrate. Clean the taint as soon
as possible to avoid harm to your
vehicle finish caused by the taint.
(3) Wash the car after the engine
cools down. Do not wash your car
in strong sunlight or under high
temperature, otherwise the detergent
will form taint on the paint surface
after quick drying. If washing the
car by yourself, please use special-
purpose detergent and neutral active
water. Do not use mild soap water and
detergent with high alkaline, which

F3DM Owner’s Manual

may wash away grease in the paint
and speed up aging. When washing
the car in car wash, you’d better
prevent the staff from using grease-
removing detergent, or the paint may
be damaged. When driving your car
in coastal areas with heavy pollution,
you shall wash the car on a daily basis.
(4) Use damp, clean and soft cotton
mitt to wipe the car, and make sure
metal and sand article does not exist in
it. Do not use dry cloth, sponge or towel
to wipe it to avoid scratching the paint.
When wiping, move the cloth gently
along the running water, and do not
move in circle or perpendicular to the
running water. Do not rub or press hard
in case that you may scratch the paint.
(5) Clean some special traces with
very strong causticity as soon as
possible (such as asphalt, bird
manure and insect remains). For

such things, please clean them with
special cleanser and do not scratch
them with a blade or clear them
up with gasoline in order to avoid
causing damage to vehicle finish.
(6) Pay attention to not touching
the paint with oily and dirty hands
or wiping it with an oily rag; please
do not stick any oily tools or put
cloth with organic solvent on the
car, to avoid chemical reaction.
(7) If there is no obvious scratch, do
not make repainting as the new paint
color may vary from the original paint.
(8) In case that the car will not be
used for a long period, please park it
in a well-ventilated garage or a similar
place, and use a special-purposed
car cover in winter. For a short period
parking, please select a shade place.
(9) Prevent strong impact, knock
or scratch to the paint. If the paint

is scratched, sinking or peeling off,
please make repair in time, and
you are recommended to go to a
professional auto beauty store.
( 1 0 ) U s e c a r b o n d e t e r g e n t t o
c l e a n g l o s s y m e t a l p a r t s , a n d
apply wax regularly for protection.
(11)High qualified cleaner is needed
when washing your decorative parts.
Do not use excessive force when
waxing to prevent the base layer from
exposing when the paint is penetrated.
Apply wax on the paint film and go
to auto beauty store for maintenance
regularly (at least once per quarter) to
keep the vehicle finish glossy.

before waxing, even if you use a

combined cleaner and wax.
2. Please use polish and car wax
with high quality. If the paint has been
seriously weathered, please use the
cleaning polish followed by a separate
wax. Follow the instructions and
precautions from the manufacturer
carefully. Make sure that polishing and
waxing is needed for the chrome as
well as the paint.
3. Wax your car again when water
does not bead but remains on the
surface in large patches.
