If headlight or other electric devices
do not work, please check the fuses.
When necessary, replace the fuses.
For information on location of fuses, see
Section 7-

1 ―Location of Fuses‖.

Turn off ignition switch and other
malfunctioning devices. Pull out the
fuses with potential malfunction
vertically and check them.
Find out which fuse has trouble. Circuit
name of each fuse is indicated on cover
of the fuse box. See Chapter 8 for
control function of each circuit.
Pull out A type fuse with a puller. The
puller is at location 19 in figure ―Engine
Compartment‖ in Chapter 8.
If you are not sure whether the fuse is
burnt out, replace it with a good one.

If the fuse is burnt out, insert a new
fuse into the fuse socket.
Only install a fuse with amperage
specified on the fuse box.
If there is no spare fuse in emergency
situation, you can pull out ―29. Indoor
Light‖ fuse, which is not essential in
driving, and substitute it for a fuse with
the same amperage.

If there is no fuse of the same amperage,
you should choose a fuse with lower
amperage; and do try to get a fuse with
the amperage as close to the rated
amperage as possible. If you use a fuse
with lower amperage, it may be burned
out again, but this doesn’t mean the car
has problem. You shall install a proper
fuse as soon as possible, and put back
the substitute fuse in place.
It is recommended to keep a set of
spare fuses on the car for emergency
use.
If a new replaced fuse is burnt out
immediately, the electrical system may
have problem. Contact BYD service
station for a check as soon as possible.

Tips

Never use a fuse with higher
amperage

than

the

rating

amperage or use any other
objects to replace the fuse,
otherwise it may cause serious
damage and may lead to fire.

Add Cleanser

If the cleaner does not work, the
cleanser tank may have been empty.
Check the cleanser level on the
content gauge. If the level is below
“LOW” mark, you shall add cleanser.

BYD G3 AUTO Owner’s Manual

145

Before Adding Cleanser
Pull out cleanser funnel and hang it
on the brake of engine hood support.
Water can be used as cleanser. But in
cold region where the temperature is
below zero degree, you shall use
cleanser with ant freezing agent. It is
available in BYD service stations and
most auto part stores. For mixing ratio of
water and anti-freezing agent, please
refer to manufacturer’s instructions.
Make sure put back the funnel in place
after filling full the cleanser tank.

Note

Don’t use engine antifreeze or
other substitutes, as they will
damage the vehicle paint.

Replace Bulb
The following figures shows the method
to take off the bulbs. Make sure the
ignition switch and light switches are
turned off when replacing bulbs. Use
bulbs with rated power shown in the
table below:
Parking light and rear parking light
consists of a group of luminous diodes.
When the number of burnt out luminous

diodes affects the car’s compliance with
local laws, please send the car to BYD
service station for replacing bulbs.

Tips

● Do not replace bulb when it is

hot to avoid burning.

● The halogen bulb is filled with

pressurized gas, please be
particularly careful. If the bulb
is scratched or falls to ground,
it may explode or crack. Only
hold the bulb on its plastic or
metal part. Do not touch glass
part of the bulb with bare
hands.

When traveling in rain or when the light
shade is wet after washing, the inside of
lamp shade of external light such as
headlight will temporarily fog. As with
fog on the windshield in rainy days, the
fog inside the light shade is due to the
temperature difference between the
inside and the outside of light shade,
and isn’t a trouble. But if there is water
droplet or water pool in the lightshade,
please contact BYD service station.
