running-in. However, within the first
2000 km, please follow the simple
instructions below to save fuel and
lengthen service life of the car.
●

Do not press the accelerator to the
full while starting and driving.

●

Avoid running the engine over-fast.

●

Do not use emergent braking within
the first 300 km.

●

Do not drive slow or fast at the
same speed.

●

Do not pull a tow within the first
2000 km.

Fuel
Please select proper fuel to fully exert
the engine performance. It will also
essential to control exhaust and

maintain related components.

Use of improper fuel might cause
damage to the engine or exceed
exhaust standard. It is not within the
guarantee scope of BYD L3 car.

Fuel type

Please use lead-free gasoline of
No.93 or above.

To avoid any mishandling in the gas
station, a small fuel tank mouth is
prepared. Only the nozzle dedicated for
lead-free oil pump matches it. Larger
nozzles of leaded oil pump do not match
it.

NOTICE

Do not use leaded gasoline. Use of
leaded gasoline will invalidate the
three-way catalytic converter and
cause abnormal work of exhaust
pollution control device. Additionally,
it also increases maintenance fee.

NOTICE

The in-car exhaust system can only
use lead-free gasoline of No.93 or
above.

If the engine knocks
If you feel severe knock when using the
recommended fuel or you hear regular
knock sound when driving at a steady
speed, please contact BYD service station.
However, you will also hear short and
weak knock sound when accelerating or
going up a slope. Don’t worry as it is a
normal phenomenon.
Rated capacity of the fuel tank

50L
Fuel Cut-off System
If the engine stops running in an
accident, the engine control system will
stop providing fuel to the engine to
reduce fuel leaking risk to the minimum.
When you want to restart the engine
after the fuel pump stops work, please

L3

Owner’s Manual

Driving Instruction for BYD L3 2-3

rotate the ignition switch to ACC or
LOCK before restarting the engine.

FRIENDLY TIPS

Before restarting the engine, please
examine the ground under the car. If
leaked fluid is found on the ground, it
indicates that the fuel system is
damaged and requires repair. In this
case, do not restart the engine.
Three-way Catalytic Converter

Three-way catalytic converter is an
exhaust pollution purifying device
which is installed in the exhaust
system.

It is used to reduce pollution substance
in exhaust.

NOTICE

● When the engine is under

operation,

persons

and

inflammable material should be
away from exhaust pipe. The
exhaust pipe gives off gas in very
high temperature.

● Do not drive the car, idle the car or

park the car on grass, tree leaves,
paper or rag (especially wheat
straw in summer) which is easy to
be burned.

NOTICE

Large quantity of unburnt gas
mixture which enters the three-way
catalytic converter will overheat the
three-way catalytic converter and
cause fire. To prevent the risk, please
take the following precautions.

●

Please use lead free gasoline
only.

●

Do not drive the car when fuel
level is very low; Car operation
with less fuel might affect the
engine and add excessive load to

the three-way catalytic converter.

●

Do not run the engine at a high
idling speed more than 10
minutes or at a low idling speed
for more than 20 minutes.

●

Avoid

running

the

engine

over-fast.

●

Do not start the engine by
pushing or pulling the car.

●

Do not turn off ignition switch
while the car is travelling.

●

Please maintain good operation
status of the engine. If electric
system,

electronic

ignition

system or fuel system of the
engine does not work normally, it
will

high

temperature on the three-way
catalytic converter.

●

If the engine is hard to start or
often

stops

running,

please

examine the car immediately.

●

To ensure normal work of the
three-way catalytic converter and
the

whole

pollution

control

device, please conduct regular
car examination in accordance
with BYD L3 car maintenance
schedule. (Refer to Chapter 6)

Engine Exhaust Warning

FRIENDLY TIPS

● Do

not

inhale

waste

gas

exhausted from the engine.

● Please

confirm

that

the

exhausting system has no leaking
hole

or

loosened

connector.

Please

examine

exhausting

system frequently. If your car
bumps

into

something

or

exhausting

sound

changes,

please

examine

the

car

immediately.

● Do not run the engine in a garage

or at a closed place unless the car
comes into or go out of a garage.
Exhaust

which

can

not

be

dissipated might cause severe
risk.

● Do not park your car for a long

time while the engine runs. If you
have to do so, please park your
car at an open place and adjust
heating or cooling system to
exchange air with outside.

● Please close the trunk cover while

driving. The trunk cover which
remains open or is not closed

tightly might draw exhaust into
the car.

● To ensure normal work of car

ventilation system, please ensure
that there is no snow, tree leaves
or other obstacles in the air inlet
grid in the front of the windshield
glass.

● If you smell waste gas in the car,

please open the window and
examine incoming position of
waste gas to take measures.

Engine Oil Consumption
Engine oil function
Engine oil is used to lubricate and cool
the engine inside and plays a major role
in keeping the engine in normal working
condition.
Engine Oil Consumption
The engine in normal working
condition consumes some engine oil.
In normal condition, the engine
consumes the engine oil due to the
following causes.

● Engine oil is used to lubricate piston,

piston ring and cylinder. When the
piston moves up and down in the
cylinder, a thick layer of oil film will
be left on the cylinder wall. When
the car decelerates, high negative
pressure will inhale the engine oil
into the combustion chamber. The
engine oil and some of oil film left
on the cylinder wall will be burnt by
high

temperature

gas

during

burning.

●

The engine oil is also used to
lubricate intake valve lever. Some
engine oil and intake air will be
drawn into the combustion chamber
and burnt together with fuel. High
temperature

waste

gas

also

consumes the engine oil used to
lubricate exhaust valve lever.

Engine oil consumption is related to
viscosity and quality of the engine oil
and car condition.
Driving at a high speed or accelerating
and decelerating frequently will increase
consumption of the engine oil.
