Owner’s Manual

Engine and Chassis 7-15

If you do not replace a damaged tire, the
tire might come off the wheel and the car
might get out of control.

Wheel selection

When replacing wheel, please use a
new wheel with same load capacity,
diameter, wheel width and offset as
the older one.

BYD authorized service station can
replace wheel correctly.

A wheel with different size or type might
inflict unfavorable effect on operation,
service life of wheel and bearing, cooling
of brake, speedometer/odometer setting,
braking

performance,

headlight

accuracy, bumper height, distance from
the ground, distance between tire or tire
chain and car body or chassis.

Do not replace with an old tire. The old
tire might have been disposed or have
run for a long way and fault might occur
without any sign. Likewise, the aligned
bent wheel has damaged structure.
Therefore, do not use it. Do not use an
inner tube designed for a tubeless tire in

a leaking wheel.

FRIENDLY TIPS

As it might cause a typical operation
risk and the car out of control, please
do not use a tire other than that with
size recommended by the manuf
-acturer. Otherwise, it might cause
death or severe injury.

Notes on Aluminum Tire

● For a car equipped with aluminum

wheel, please check to make sure
the wheel nut is tightened within the
initial 1600 km.

● If a tire is exchanged, repaired or

replaced, please check to make sure
the wheel nut is tightened after
driving for 1600 km.

● While using tire chain, take care not

to damage the aluminum wheel.

● Please use BYD wheel bolt and

spanner designed for aluminum
wheel only.

● When adjusting wheel balance with

tire chain, please use BYD balance
block and plastic hammer or rubber
hammer only.

● Just as with any other the vehicles,

please check to make sure the
aluminum wheel is not damaged. In
the case of damage, please replace
immediately.

L3

Owner’s Manual

Electrical Appliance Parts 7-20

A type

B type

C type

If headlight or other electric parts do
not work, please check fuse. If fuse is
burned, please replace it.

Fuse layout, Refer to Chapter 7-

1 “Fuse

layout”.

Turn off ignition switch and parts that
do not work. Pull out the fuse in
question vertically for examination.

Determine which fuse is out of order.
Circuit name of each fuse is marked on
fuse box cover. For control function of
each circuit, please refer to chapter 8 in
the manual.

Use a pulling tool to pull out the fuse of
type A. For position of pulling tool, refer
to 19 “piece puller” in figure “engine
compartment” in Chapter 8.

If it can not be determined whether fuse
has been burned, please replace the
fuse in question with a better fuse.

If fuse has been burned, please insert
new fuse into the socket.

Please install the fuse with amperage
specified on fuse box cover.

If no spare fuse is available, In the case
of emergency, please pull out the fuse of
“29. In-car lamp” which is dispensable
during ordinary driving and replace with
it, if it has the same rated amperage.

If no fuse with the same amperage is
available, please use fuse with lower
amperage and try to reach the rated
amperage. If a fuse with amperage
lower than specified value is used, it
might be burned again, but this does not
mean any problem. Please replace with
correct fuse as soon as possible and
insert it into the socket.

It is recommended to purchase a set of
spare fuse and store it in the car for use
in emergency.

If newly replaced fuse is burned soon, it
indicates that electric system might have
a trouble. Please contact BYD authorized
service station for examination and
repair.

L3

Owner’s Manual

Electrical Appliance Parts 7-21

FRIENDLY TIPS

Never use fuse whose amperage is
higher than rated value or anything
else. Otherwise, it might cause
severe damage and cause fire.

Add Cleanser

If a cleaner does not work, it could be
because that the cleaner overflow
kettle might have become empty.
Please check cleaning mixture level
on level gauge. If cleanser level is
lower t

han “LOW”, please add

cleanser.

Before adding cleanser

Pull out the cleanser funnel and hang
it on support holder of the engine
hood.

Clean water may serve as cleanser.
However, in a cold area, when
temperature is below 0 degree of
centigrade,

please

use

cleanser

containing anti-freezing agent. The
product is available in BYD authorized
service station and most automobile
parts shop. Refer to the manufacturer
instruction for mixture ratio of water.

L3

Owner’s Manual

Electrical Appliance Parts 7-22

FRIENDLY TIPS

●

In order to prevent scald, do not
replace a bulb while it is hot.

● As halogen lamp has pressurized

gas inside, please take great care.
If a bulb is scraped or falls down,
it might explode or crack. Please
hold plastic part or metal box of
the bulb. Do not touch glass part
of the bulb.

When the car travels in a rainy day or its
rear lamp cover is dampened after
washing the car, lamp shade of
headlight or other external lamps might
fog temporarily. Just as a windshield
glass fogs in a rainy day, the fogging
phenomenon is caused by temperature
difference between inside and outside of
lampshade, which is not a malfunction.
However, if there is large water drops
inside the lampshade or there is
accumulated inside the lamp, please
contact BYD authorized service station.
