Anti-Corrosion of BYD L3 Car

Proper car maintenance prevents the
car from corrosion for a long time.

Car corrosion is most often caused by:

●

Alkaline substance, dust and damp
air are accumulated below the car
where it is hard to reach.

●

Paint layer or bottom layer is
damaged by slight collision or stone
or gravel.

If you live in a special area or drive
the car in a special environment, be
sure to take care.

●

Alkaline substance or chemical
substance on the road might
accelerate corrosion. Air in coastal
area or industrial pollution area also
contains alkaline substance.

●

High humidity might accelerate
corrosion, especially when the
environment temperature is just
above zero.

●

When some parts of the car is wet
or damp for a long time, even if
other pars remain dry, it will also
cause corrosion.

●

High temperature might cause
corrosion to car components which
are not dried due to lack of proper
ventilation.

The items stated above represents that
it is important to keep the car clean,
especially car bottom, and recover
damaged paint layer and protection
layer as soon as possible.

To prevent corrosion of BYD L3 car,
please observe the following rules:

Wash the car regularly. Regular
washing keeps the car clean. However,
in order to prevent corrosion, please
observe the following points.

●

If you drive the car on a road
containing alkaline substance or at
seaside, please wash the travelling
part of the car once a month at least
to reduce corrosion.

●

High pressure or steam is very

effective to car chassis and wheel
cover washing. As it is difficult to
see mud and dirt at these places,
please take great care. If you only
dampen mud or debris instead of
removing them, it might cause
greater harm. Do not block the
lower edge and threshold board of
car doors and water outlets of the
car frame with dust. Otherwise
water accumulated at these places
will cause corrosion.

●

After winter, please wash the car
chassis thoroughly.

For more tips, please refer to “car
washing and waxing”.

Examine paint and decoration parts. If
you find any fragment or flaw on the
paint

layer,

please

make

repair

immediately to prevent corrosion. If the
fragment or the flaw comes off the metal
surface, please contact BYD authorized
service station for repair.

Examine car inside. Moisture and dust
are accumulated under the floor mat and
cause corrosion. Please examine the

L3

Owner’s Manual

Anti-Corrosion and Automobile Exterior Maintenance 5-3

mat and ensure that it is dry. When
transporting

chemical

substance,

detergent, chemical fertilizer and salt,
please take extra care and use proper
container. If the liquid splashes out or
leaks, please clean it immediately and
keep dryness.

Use a splash guard. For example,
when driving on saline alkali area or
gravel road, the splash guard can
protect the car. A splash guard with
larger size which approaches the
ground is preferred. The small splash
guard for the wheel cover of BYD L3 is
an optional part. BYD authorized
service station will install splash guard
for your car.

Park the car at a well ventilated
garage or roofed place. Do not stop
the car in a damp and badly
ventilated garage. If you wash the car
in a garage or drive the car on watery or
snowy road, the garage will become
damp and cause corrosion. Even if the
garage is dry, bad ventilation will still
corrode damp car.

Instruction

on

Lacquer

Surface

Maintenance

Pay attention to the following points in
car maintenance.

1. Please clear dust on the car before,
while and after you drive the car to
reduce absorption of dust by static
electricity on the car.

2. Wash after rain. Water stain will shrink
gradually after rain, which increases
acid substance concentration. If you do
not wash it off, it would damage paint
surface.

3. Be sure to let the engine cool down
before washing your car. Don't clean
your car in the hot sun or at a high
temperature in order to avoid any mark
resulting from the dried detergent. While
washing the car by yourself, please use
dedicated detergent and fresh neutral
water. Do not use washing powder, soap
water or detergent with strong alkali,
which might wash off oil in the paint
surface and accelerate paint surface
ageing. When washing in the garage, do
not use dewaxing detergent to avoid

damage to the paint surface. Especially
when driving in coastal area or severely
polluted area, please wash the car once
a day.

4. Use clean and soft cloth or sponge to
clean car and avoid mixture of metal
chip and sand. Do not use dry cloth, dry
tower or dry sponge to clean car to avoid
scratching. Wipe the car in the direction
of flowing water, do not draw circles or
wipe horizontally.

5. For some special and very corrosive
trace (such as asphalt, bird shit or
insect), please clean it immediately. In
this

case,

please

use

dedicated

detergent. Do not use blade to scratch it
or use gasoline to eliminate it, which
might damage the paint surface.

6. Do not touch the car paint surface
with oily hand or wipe the paint surface
with oily cloth. Do not place oily tool or
cloth stained with organic solvent on the
car to avoid chemical reaction.

7. If there is no obvious scratch on the
paint surface, do not paint the car for a
second time to avoid un-matching paint
color or bad bonding.

L3

Owner’s Manual

Anti-Corrosion and Automobile Exterior Maintenance 5-4

8.

If the car isn’t in use for a long time,

please park it in a garage or well
ventilated place. Cover it with dedicated
car cover in winter. Please select a
shady place to park your car.

9. Avoid intense impact, bump and
scratch on paint film. If there is scar,
dent or coming off on the paint surface,
please make repair immediately. A
professional automobile beauty shop is
preferred.

10. To wash a plated metalware, please
use carbon detergent and regularly
wash it to protect it.

11. To wash decoration parts of the car,
please use quality detergent. While
waxing the car, do not use too much
force to avoid penetrating the painting
layer and expose the base.

Irregularly wax the paint surface and
regularly (once per quarter) to receive
maintenance

in

a

professional

automobile shop and recover gloss of
the paint surface in time.

clean carpet. Clean it in a circular way.

Do not use water in order to keep the
carpet dry. Read carefully and follow
strictly instruction on detergent use.

Seat Belt

Use neutral soap water or slightly
warm water to clean a seat belt.

Use sponge or soft cloth and check
whether the seat belt buckle is
excessively worn, damaged or cut
during cleaning.

NOTES

●

Do not use dye or bleacher to
clean seat belt buckle. Oth
-erwise, it might weaken the
strength of seat belt.
