Piston, piston ring and cylinder wall of a
new the engine consumes more the
engine oil as they have not experienced
run-in period.

Engine Oil Consumption

When determining the engine oil
consumption, please note that it
might be difficult to determine an
actual oil level due to diluted the
engine oil.

For example, if the car travels 1000km
in repeated short-distance trip and
consumes normal quantity of the engine
oil, oil dipstick shows no drop. As the
engine oil is diluted by fuel and steam,
oil level does not drop.

While the car is traveling in high speed,
for example on a highway, the diluted
the engine oil will be vaporized.
Therefore, you will find excessive
consumption of the engine oil after
driving at a high speed.

Importance of the engine oil level
check

It is an important point in car
maintenance to keep the engine oil level
at the optimistic position so as not to
weaken

the

engine

oil

function.

Therefore, regular examination of the
engine oil level is very important. It is
recommended to check the engine oil
level every time you refuel the car.

NOTICE

If the engine oil level is not checked
regularly, insufficient the engine oil
might cause severe engine fault.

For details of the engine oil level check,
please refer to “engine oil level check” in
Chapter 7-2.

Gear Shifting

NOTICE

Do not shift to the reverse gear until
the car is totally stopped. Shifting to
the reverse gear before the car is
totally stopped would damage the
transmission.

Manual transmission

To run the car in a steady way, manual
transmissions in all forward gears are
synchronous. Manual transmission is
equipped with locking device to avoid
direct gear shifting from the fifth gear to
the reverse gear. When shifting gear,
please press the clutch to the full. When
not shifting gear, do not put your foot on
the clutch pedal. Otherwise, it will speed
up clutch wearing.

Wait for a few seconds after pressing
the clutch pedal and before shifting to
the reverse gear. Or wait for a moment
after shifting to a forward gear. This will
stop gear running and avoid mutual
“grinding”.

When decelerating, the decreasing gear
will receive extra braking force from the
engine. The additional braking power
helps keep a safe speed. When
travelling down a slope, it will prevent
brake overheating.

FRIENDLY TIPS

When travelling on a slippery road,
dramatic acceleration or dramatic
deceleration might cause the car out
of control. Consequent collision
accident might cause harm on you.
When driving on slippery road,
please take extra care.

lowest gear (1st gear) position.

Selection of sport mode (S)

WARNING

1. If your car is still allowed to move
after shutting off the engine and
shifting into N, the transmission can
be badly damaged due to lack of
effective lubricating.
2. If the engine operating and shifting
into R\D\S already, be sure to press
on the brake pedal and hold it there
to stop your car. Because even if the
engine is idling, the power train can
still transfer power so that your car
can drive forward slowly.
3. When driving, if needed to change
gears, to avoid accident, d

oesn’t

press on the accelerator pedal.
4. During driving, don't shift the shift
lever into R or P in order to avoid
accident.
5. Don't let your car go down hills
with the shift lever in N or P even if
the engine stops running.
6. To prevent your car from moving
accidentally, after parking your car on
level ground, be sure to pull up the
parking brake lever and shift the shift

lever into P.
With the shift lever in D position, push
the shift lever to the left side directly
instead of performing operation of
upshifting/downshifting. In this case, you
can select the sport mode. The gear
display on the combination instrument
panel shows you D1, D2, D3, D4, D5 or
D6.

Selection of manual mode (M)

With the shift lever in D position, push
the shift lever to the left side firstly, and

backward. In this case, you can select
the manual mode. The gear display on
the combination instrument panel shows
you the current gear position of M1, M2,
M3, M4, M5 or M6.

Explanation:

1 The shift lever is in the same position
under sport mode and manual mode.

2 If it is necessary to shift from M to S
again, you must shift the shift lever into
D and then into S.

L3

Owner’s Manual

Driving Instruction for BYD L3 2-8

3 Under the sport mode, the first
operation of upshifting/downshifting is
defaulted as the switch signal of
entering the manual mode so that the
transmission

will

not

operate

accordingly.

Starting out your car

When start the engine, you must shift
the shift lever into P or N.

Parking

If you need to park your car, you must
release the accelerator pedal and press
on the brake pedal. After a complete
stop, you must pull up the parking brake
lever, and finally shift the shift lever into
P.

NOTES

●

When parking your car on a slope,
make sure to press on the brake
pedal and hold it there and pull up
the parking brake lever. Don't use
the method for pressing on the
accelerator pedal with the shift
lever in D position to stop your car

from going down hills, which can
cause overheating or bad wear to
the transmission clutch.

●

When parking, before shifting the
shift lever into P, make sure to pull
up

the

parking

brake

lever.

Because when parking your car on
a slope, releasing the brake pedal
can cause your car to go down
slightly.

Before

shifting

the

transmission into P, pulling up the
parking brake lever can avoid
applying a pressure to the parking
device inside the transmission
when your car moving. As a result,
when you want to drive your car
away, you can shift the shift lever
out of P more easily.

Starting on hills

To protect the DCT transmission, be
sure to apply the parking brake to assist
in starting your car on steep hills.

Special environment

If you encounter downhills, corners, or
mountain roads, it is recommended to

use the manual mode and shift into a
lower gear in order to make full use of
engine braking.

FRIENDLY TIPS

Prolonged

frequent

starting,

or

prolonged slow driving or prolonged
stop-and-go driving with traffic can
cause overheating

to

the

DCT

transmission clutch.
If the DCT transmission clutch is
overheated, the instrument panel will
show a warning signal. In this case,
to protect the clutch from being
damaged, the transmission control
module will disengage the clutch so
that your car cannot drive. If this
occurs, be sure to press on the brake
pedal and hold it there to park for
several minutes. Let the transmission
cool down for a period of time before
driving again.

Parking control mechanism

Pull up the parking control mechanism
tightly to avoid unexpected sliding while
parking. To avoid accidental slide of the
car, it is recommended to use position 1

L3

Owner’s Manual

Driving Instruction for BYD L3 2-9

when parking the car on a horizontal
road. It is recommended to use position
1 when parking the car on the upward
slope. It is recommended to use reverse

Braking System

Design of braking system

L3

Owner’s Manual

Driving Instruction for BYD L3 2-10

There are two independent circuits for
hydraulic system of the brake. Each
circuit acts by crossing the car in
diagonal direction (the front left wheel
brake connected with rear right wheel
brake). In the case that one circuit fails,
the other two wheels can be braked.

Disc-and-drum brake

The car is equipped with disc-and-drum
brake. For this type of braking system,
brake shoe should be run in regularly or
after replacing brake shoe or braking
drum.

BYE authorized service station will
perform running-in.

ABS braking device

ABS helps prevent wheel skid In the
case of emergent braking to help your
control steering.

When the front wheel skids, you cannot
control steering. That is, even if you
operate the steering wheel, the car still
travels forward straightly. ABS helps
prevent skid and pulse braking is much
faster than human reaction. Therefore, it
helps maintain steering control.

ABS balances distribution of front/rear
wheel braking power in accordance with
car load.

Do not press the braking pedal in a
pulse way. Otherwise, ABS will lose
control. When operating the steering
wheel to avoid danger, please inflict a
powerful and steady pressure on the
braking pedal to help ABS function. As it
is often said, “press steadily, and turn
accurately”.

When ABS starts, you will feel that
braking pedal vibrates and might hear
noise. This is a normal phenomenon, as
ABS is performing fast braking in a
pulse way.

Fast/slow function of ABS depends on
driving force (adhesive force) of the tire.
On dry and paved road, please step the
braking pedal with force to activate ABS.
However, if you want to park your car on
snowy or icy road, you can feel ABS
function immediately.

Important safety tips ABS (anti-lock
brake system) cannot shorten the time
and distance required for braking your car.
The device is designed to help you control
steering while braking only. You should
always keep safe distance from other the
vehicles.

ABS cannot prevent skid caused by
sudden change of direction, for example
when you turn the car sharply or change
a lane suddenly. Whatever the road
condition or weather condition is, you
should always carefully drive your car at
a safe speed.

L3

Owner’s Manual

Driving Instruction for BYD L3 2-11

ABS cannot prevent reduction of
steadiness either. When you brake your
car suddenly, please turn your car
appropriately. Large turn or sharp turn
during driving might leave the car turn to
vehicle flow on the opposite side or get
out of the road.

Compared with a car without ABS, a car
with ABS might require more braking
distance while driving on soft or bumpy
road (such as gravel road or snowy
road). In such a case, please decrease
car speed and keep quite a distance
from other the vehicles.

ABS indicator

ABS has self-examination function. In
the case of any fault, the ABS indicator
on the instrument panel will be turned on
(please refer to combined meter). It
means that ABS function of braking
system doesn’t work. At this time, the
brake only provides ordinary braking
function as that of an ordinary car
without ABS. Please contact BYD

authorized

service

station

for

examination.

If the ABS indicator and braking system
indicator are turned on at the same time
while the hand brake is released to the
full, it indicates that front/rear wheel
braking distribution system does not
work.

Press the braking pedal slightly to feel
whether it is normal. If it is normal,
please check braking fluid level next
time you pull off at a oil station (refer to
the section about braking fluid check). If
the fluid level is low, please contact BYD
authorized service station to check
leakage of braking system and wearing
of brake block.

However, if the braking pedal doesn’t
feel normal, please take measures
immediately. As the braking system is of
two-circuit design, even if part of the
system fails, you can still brake the other
two wheels. At this time, you must press
the braking pedal more deeply to
decelerate the car and braking distance
become longer.

L3

Owner’s Manual

Driving Instruction for BYD L3 2-12

Shift to a low position to decelerate the
car and pull the car off the road safely.
As a long parking distance is required, it
is dangerous to drive the car. Please
have the car towed away and repaired
as soon as possible.

If you have to drive for a short distance
in the situation, you must drive the car
very carefully.

Drive in Bad Weather

Due to reduced driving force (adhesion
force) and visibility in a rainy, foggy or
snowy

day,

different

environment

requires different driving skills. You
should maintain your car. If you have to
drive in bad weather, please take extra
care. In these cases, do not use cruise
control (limited to a type).

Driving skill

—Traveling speed should

be slower than in dry weather. Even if in
a seemingly damp condition, your car
requires a long time to react and inflict
steady and balanced pressure on all
control devices. Sharp turn or sharp
brake in damp weather might cause the
car out of control. Please take care of

driving before you are accustomed to
changed driving condition, especially in
a snowy day. A driver might forget about
driving skill on snowy road after the few
summer months and has to practice to
recollect the skills.

Take great care when driving in a rainy
day after a long dry season. The first
rain after continuous dryness might
cause oil to float on the road, which
therefore becomes slippery.

Visibility

— In all weather conditions, it is

very important to see surrounding and
be seen by other the drivers. It is difficult
to do so in bad weather. Therefore,
please turn on the headlight even if in
daytime.

Please examine windshield wiper and
washer

regularly.

Make

sure

that

windshield washer container is stored
with sufficient cleanser. If the wiper
doesn’t work thoroughly or leave a stripe
on the windshield, please change the
wiper. Additionally, defroster and air
conditioner are used to avoid fog in the
car.

Driving force (adhesive force) - Always
check whether tire wear conditions are
modest and tire pressures are proper.

These items are very important to
prevent your car from aquaplaning
(loss of adhesive force on a slippery
surface). In winter, four wheels should
be equipped with snow tire (with
anti-skid tread) to achieve optimistic
operation performance.

Please carefully observe constantly
changing road conditions. Damp tree
leaves might be as slippery as snow and
ice. “Clean” road might be dotted with
thin ice. When external temperature
approaches zero degree centigrade,
driving condition is very dangerous as
road might be covered with interwoven
water and ice. Therefore, adhesion force
of a car might change suddenly without
any sign.

When you decrease shift, please take
great care. If adhesion force is weak,
driving wheel might be locked for a
moment, which might also cause skid.

L3

Owner’s Manual

Driving Instruction for BYD L3 2-13

When overtaking other the vehicles or
being overtaken by others, make sure
you will take great care. Water mist
caused by heavy-duty the vehicles
might baffle your vision and air billow
might cause your car out of control.

Note: Please do not drive on road where
there is deep water. Car driving in water
might cause failure or damage of the
engine and electric devices.

Engine Fault Indicator

The indicator will remain on for a few
seconds after you turn the ignition
switch to ON (II). If it is turned on at any
time, it indicates that fault might occur to
discharging control system of the engine.
Even if you do not feel abnormal
condition of the car, the fault might
reduce oil saving performance and
discharge more exhaust. The engine
which continues running in the condition
might result in severe damage.

If the indicator is turned on, please pull
your car off the road safely and turn off
the engine. Restart the engine and
check the indicator. If the indicator
remains on, please contact BYD
authorized

service

station

for

examination.

Before

the

fault

is

determined in BYD authorized service
station, please take care while driving
and avoid wide open of accelerator and
high-speed travel.

In the case that the indicator turns on
frequently, even if it is turned off after
handling in accordance with above
stated procedure, please contact BYD
authorized service station for car
examination.

FRIENDLY TIPS

If you keep on driving while the fault
indicator is on, it would damage
discharging system and the engine
itself. This kind of repair is not
included in warranty range.

L3

Brake Lining Warning Piece

The Brake lining piece on disc brake
will send out alarm when the piece is
worn and requires replacement.

If you hear sharp sound or friction sound,
please contact a nearby BYD authorized
service station for examination and
piece replacement.

Do not continue driving the car while the
alarm rings.

Notes on Luggage Loading

When the car is loaded with luggage or
goods, please observe the following
instructions.

●

Place your luggage and goods in
the trunk. Please confirm that all
goods are fixed in place.

●

Please keep balance of the car.
Please place weight in the front to
keep balance.

●

In order to save fuel, do not load
unnecessary weight.

Suspension and Chassis

FRIENDLY TIPS

Do not use lifting tool, spacer or
spring to refit suspension/ chassis.
This will cause damage to control
performance and cause the car out of
control.

passengers. Towing a trailer can have
adverse effects on the manipulation,
performance,

braking,

durability,

economic driving (fuel consumption) and
other aspect. Safety and comfort of
driving totally depends on correct use of
equipment and careful driving habit. For
the safety of you and other people,
please do not overload the car or tow a
trailer. BYD is not liable for damage or
fault caused by towing a trailer for a
commercial purpose.

Weight limit

Before towing a car, please confirm
towing capability of the car. Please
contact local BYD authorized service
station and confirm that towing capability
of the car is within specified scope.

Towing capability is measured on
horizontal road. If the car is traveling in
mountainous area, its engine power and
towing capability will be reduced.

FRIENDLY TIPS

The weight of the trailer to be towed
should not exceed the maximum
rated weight of the tow hook.
Otherwise, this can cause accidents,
resulting in serious personal injuries.
Due to possible increase of braking
distance, be sure to increase the
distance between your car and the
trailer when towing a trailer. The
distance between the car and a car in
the front of it should be at least the
sum of the car and its trailer at a
speed of 10 km/h. Please avoid
emergent braking to prevent car
folding and control loss caused by
skid.
