Fuel

Appropriate fuel can give full play to
engine performance, while reducing
exhaust

emission

and

allowing

simple maintenance of parts.

Engine  damage  or  incompliance  of
emission as a result of improper fuel are
not covered by BYD warranty.

Fuel Type

Only  use  #93  or  above  unleaded
gasoline.
To  prevent  wrong  operation  in  gas
station,  BYD  G3  is  equipped  with  a
small  fuel  tank  opening.  The  special
nozzle  of  unleaded  gasoline  pump  can
match  up  with  the  small  opening  while
the  larger  standard  nozzle  of  leaded
gasoline pump can not.

Note

Do not use leaded gasoline, which
may cause failure of three-way
catalytic

converter

and

abnormality of emission pollution
control device. It will also increase
maintenance expense.

Note

Emission system on BYD G3 is
only intended for #93 or above
unleaded gasoline.

Engine Knock

When you are using fuel recommended
by  BYD  dealer,  in  case  of  serious
engine  knock,  or  if  you  hear  regular
knock  sound,  please  contact  BYD

Fuel Cut-off System

In  case  of  accident,  when  the  engine
stops running, the engine control system
will  cut  off  fuel  supply  to  the  engine  to
reduce the danger of fuel leakage to the
minimum.  When  fuel  pump  stops  work,
to  restart  the  engine,  turn  the  ignition
switch to ACC or LOCK, then restart it.

Tips

Check  the  ground  under  the  car
before  restarting  the  engine.  If
any liquid leakage on the ground,
the fuel system may have damage
and  need  repair.  Do  not  restart
the engine in this case.

Three-Way Catalytic Converter

Three-way  catalytic  converter  is  an
emission  pollution  control  device
integrated in emission system.

It  is  intended  to  reduce  pollutant  in
emission.

Note

● When the engine is running,

stay

away

and

keep

inflammable  material  from  the
exhaust pipe. The hot gas from
the  exhaust  pipe  may  cause
injury or fire.

● Avoid driving on ground

covered  with  grass,  leaves,
paper  or  other  inflammable
objects,  and  it  is  especially
prohibited  to  park  the  car  or
leave  the  engine  running  idle
on such ground.

Note

Large amount of uncombusted
mixture

gas

entering

the

three-way catalytic converter may
cause overheat of the converter
and even fire. To prevent such
danger,

please

follow

the

instructions below:
◆ Only use unleaded gasoline.
◆ Do not drive the car when the

fuel  level  is  extremely  low;
insufficient  fuel  may  cause
misfire  in  the  engine  and
overload in three-way catalytic
converter.

◆ Do not let the engine run for

over  10  minutes  at  high  idle
speed  or  over  20  minutes  at
low idle speed.

◆ Do not let the engine runs

overspeed.

◆ Do not push or pull the car for

starting.

◆ Do not turn off ignition switch

in driving.

Always keep the engine at

optimum conditions. If electrical
system,

electronic

ignition

system  or  fuel  system  has  fault,
the  three-way  catalytic  converter
will get overheated.

-------------------------------------------------------------------------------------------------------------------------------------------------------------

BYD G3 AUTO Owner’s Manual

◆ Please the engine has trouble

in starting or stalls frequently,
please

check

the

car

immediately.

To ensure normal operation of

three-way catalytic converter
and the whole emission control
system,

regular

required. (See chapter 6.)

Engine Exhaust Warning

Tips

● Avoid breathing in exhaust gas

from the engine.

● Make sure the exhaust system

has

leakage

loose

connection.  Please  check  the
exhaust system  regularly.  If  the
car  has  a  collision  with  any
objects  or  when  you  hear
abnormal exhaust noise, please
check

the

exhaust

system

immediately.

● Do not run the engine in garage

closed

space

except

entering/exiting

the

garage.

High concentration of exhaust
gas is severely dangerous.

● Do not stop the car with the

engine running for a long time. If
you have to, park the car in
open space and adjust
heating/cooling air system to
take fresh air into the car.

● Lock up trunk lid in driving.

Open  or  loosened  trunk  lid  or
rear  door  may  cause  exhaust
gas entering the car.

● To ensure normal operation of

ventilation system, keep the
intake

grid

before

the

windshield free from snow,
leaves or other stuff.

● If you smell exhaust gas within

the  car,  open  the  window
immediately,  find  out  the  place
from  where  the  exhaust  gas
entered, and make correction.

Consumption of Engine Oil

Function of Engine Oil
Engine oil is used to lubricate and cool
the inside of the engine and play a major
role in maintenance to keep the engine
at normal running status.

Consumption of Engine Oil
The  engine  consumes  some  engine
oil  in  normal  running  status  for  the
following causes:

● Piston, piston ring and cylinders are

lubricated  by  engine  oil.  When  a
piston moves downwards in a cylinder,
a  film  of  engine  oil  will  be  formed  on
the  cylinder  wall.  In  deceleration,  the
resulting  high  negative  pressure  will
suck in engine oil from the film to the
combustion  chamber.  The  sucked-in
engine  oil  will  combust  together  with
the oil film on the cylinder wall during
the  high-temperature  combustion  in
the chamber.

● The intake valve stem is also

lubricated by engine oil. Some engine
oil  is  sucked  in  together  with  the
intake air to the combustion chamber
and  participates  in  combustion.  High
temperature  exhaust  gas  may  also
combust  engine  oil  used  to  lubricate
the exhaust valve stem.

Consumption  speed  of  engine  oil
depends on its viscosity and quality and
actual vehicle conditions.

High  speed  driving  and  frequent
acceleration/  deceleration  will  increase
consumption of engine oil.
New engine may consume more engine
oil  as  the  pistons,  piston  rings  and
cylinder walls shall undergo running-in.

Consumption of Engine Oil
Pay close attention that the engine oil
consumption  may  not  be  judged
correctly by engine oil level because
the engine oil may be diluted.

For  example,  after  the  car  has
undergone repeated short trips (such as
1,000  km),  the  engine  oil  level  on
dipstick  may  have  not  dropped  even
when  engine  oil  is  consumed  normally.
The  fact  that  the  engine  oil  has  been
diluted  by  fuel  and  steam  make  the  oil
level stay at the original  position on the
dipstick.
During high-speed driving, such as a trip
on express way, the foreign matter may
be  evaporated.  As  a  result,  the  engine
oil  level  may  drop  sharply  after  a
high-speed trip.

Significance  of  Checking  Engine  Oil
Level

One  of  the  key  points  in  vehicle
maintenance is to keep the engine oil at
optimum  level,  which  allows  normal
function of the engine oil. In one word, it
is important to check the engine oil level
regularly.    You  are  recommended  to
check the engine oil level every time you
refill gasoline.

Note

If the engine oil level is not
checked

regularly,

insufficient

engine oil may result in severe
engine faults.

For details on checking engine oil level,

please refers to ―Check Engine Oil
Level

‖ in Section 7-2.

Gear Shift

Manual Transmission
For

stable

running,

the

manual

transmission  is  synchronized  on  all
forward  gears.  A  lock-up  device  is
available  to  prevent  gear  shift  directly
from  5

gear to reverse gear. In gear

shift,  you  shall  step  the  clutch  pedal  to
the bottom; do not stay your feet on the
clutch  pedal  when  you  are  not  make
gear  shift,  otherwise  the  clutch  wear
may be speeded up.

Note

Shift to R gear only after the car
stops completely, otherwise the
transmission may be damaged.

After stepping  on  the  clutch  pedal,  you
shall wait for a few seconds before shift
to  reverse  gear,  or  shift  to  a  forward
gear and wait for a few seconds. In this
way,  the  gears  will  stop  rotating,
avoiding milling on each other.

In  deceleration,  downshift  can  provide
additional braking force from the engine.
Such  additional  braking  force  helps  to
keep  the  car  at  safe  speed,  especially
on downhill road it can prevent the brake
from overheating.

！

Warning

On slippery road surface, high
acceleration and deceleration may
cause the car out of control. Once
a collision occurs, you may suffer
personal injury.
Take special care when driving on
slippery road.

CVT Transmission
Position of Gear Shift Lever
Gear  shift  lever  has  four  positions.
When starting the engine the lever shall
be  in  P  (Parking)  gear  or  N  (Neutral)
gear.    When you park the car at D, N or
R gear, you shall step on braking pedal
forcibly  with  the  feet  away  from
accelerator pedal.
P gear

– at this position the transmission

is locked up mechanically. The lever
shall

this

gear

when

starting/shutting  down  the  engine.  To
get out of this gear, step on the braking
pedal  with  your  feet  away  from  the
accelerator pedal.
If the procedure above fails to get gear
shift lever out of P gear, please refer to

―Release Gear Shift Locking‖.

To  avoid  damaging  the  transmission,
you  shall  shift  to  P  gear  only  after  the
car stops completely.
R gear

– for gear shift from P gear to R

gear,  please  refer  to  description  on  P
gear. To shift from N gear to R gear, you
shall stop the car completely first.
N  gear

– to restart the engine after it

stalls, or to stop the car temporarily with
the  engine  running  idle,  you  can  use  N
gear. You shall shift to P gear whenever
you leave the car.
D  (driving)  gear

– it is used in driving.

The  transmission  will  select  proper
gears  according  to  vehicle  speed  and
acceleration,  When  the  engine  is  cold,
you  can  feel  that  the  transmission
upshifts quickly, which is helpful to warm
up the engine.

-------------------------------------------------------------------------------------------------------------------------------------------------------------

BYD G3 AUTO Owner’s Manual

When  using  D  gear,  to  speed  up
acceleration, please step the accelerator
pedal to the bottom to upshift the  gear.
The  transmission  will  upshift  by  one
grade  or  two  grades  according  to  the
speed  you  step  on  the  accelerator
pedal.

S  (sport)  mode

– when using sport

mode, push the gear shift lever upwards
to upshift, and downwards to downshift.

Release Lock by Gear Shift
When you cannot get the lever out of P
gear  by  regular  way  (step  down  the
braking pedal), please use this device.
1. Shut down the engine and pull up the
hand brake.
2.  Press  P  gear  releasing  button,  and
switch the gear shift lever from P gear to
N gear.
3.  Step  down  braking  pedal  and  restart
the engine.

If you need to release lock by gear shift,
it  means  the  car  has  fault.  You  shall
have  your car checked  by  BYD  service
station.

Hill Start
To  protect  CVT  transmission,  when
starting the car on steep slope, you shall
make  hill  starting  assisted  by  parking
lever. Or the car may slide downwards,
which  may  result  in  damage  to  the
transmission.

Self-adaptive  Update  of  Transmission
Clutch
You  shall  make  self-adaptive  update  of
transmission  clutch  in  the  following
cases:
1. TCU program is updated.
2. A new TCU is installed.
3. A new gearbox is replaced.
The  self-adaptive  procedure  of  the
clutch is as follows:

1  Stop the car completely.
2  Run the engine.
3  Set  throttle  valve  opening  to  0%

(do not step the accelerator pedal).

4 Make the engine run at stable idle

speed.

5 Make the engine run with stable

torque.

6 Press footbrake.
7 Make the following gear shift.

 Shift from N gear to D gear for 4

times,  staying  at  each  position  of  N
gear  and  D  gear  for  at  least  6
seconds.

 Shift from N gear to R gear for 4

times,  staying  at  each  position  of  N
gear  and  R  gear  for  at  least  6
seconds.

Parking Brake
When parking the car, apply the parking
brake firmly to prevent random  move of
the  car.  To  prevent  the  car  from
unwanted  move,  when  parking  on  flat

recommended to shift the gear lever to 1
position; when parking on downhill slope,
it is recommended to shift the gear lever
to R gear.

Before  driving,  make  sure  that  parking
brake  is  released  fully  and  the  parking
brake indicator goes out.
To prevent the car from unwanted move,
after the car is stopped completely,  you
shall  apply  the  parking  brake  firmly.  In
addition,  it  is  recommended  to  shift  the
gear shift lever out of N gear, specifically,
to 1 gear on flat ground or uphill slope or
R gear on downhill slope.
Apply  parking  brake  and  shift  the
transmission  to  non-N  gear  (1  gear  is

Brake System

Design of Brake System

The  hydraulic  system  driving  the  brake
has  two  independent  loops.  Each  loop
acts in the diagonal direction across the
car, linking the left front wheel and right
rear  wheel,  ect.  If  one  loop  has  fault,
another  two  wheels  still  have  brake
function.

Disc (Drum) Parking Brake
The  car  is  equipped  with  disc  (drum)
parking brake. This kind of brake system
requires  running-in  to  the  brake  shoe
regularly,  and  especially,  after  brake
shoe  and/or  brake  disc  (drum)  is
replaced.
Running-in  shall  be  conducted  by  BYD
service station.

Anti-lock Brake System

ABS  helps  to  prevent  the  wheels  from
locking  or  skidding  in  hard  braking,
allowing steering control in braking.

When  the  front  wheels  are  skidding,
steering  control  is  not  available,  which
means  even  if  you  rotate  the  steering
wheel,  the  car  keeps  running  ahead
straightly.    ABS helps to prevent wheel
locking,  and  keeps  the  steering  control
available  as  the  quick-acting  pulse
brake  responds  much  faster  than  the
driver.
ABS  also  distributes  braking  forces  on
all wheels according to the load status of
the car.

Do  not  step  on  the  brake  pedal
repeatedly  in  a  short  time,  otherwise
ABS may fail. When steering the car to
avoid danger, you shall keep stable and
strong  pressure  on  the  brake  pedal  so
as to give full play to ABS. Sometimes it
is  called  ―Stepping  stably,  steering
accurately‖.

When ABS acts, you will feel a shake on
the brake pedal and sometimes you will
hear  noise.  This  is  normal  when  ABS
makes quick-acting pulse braking.

The ABS response time depends on
tire

s’ driving force (adhesive force). On

dry  and  paved  road,  you  shall  step  on
the brake pedal forcibly  to enable ABS.
But if you want to stop the car on snowy
or freezing road, you can feel that ABS
acts quickly.
Important Safety Tips
ABS  can  not  reduce  the  time  and
distance  required  for  braking.  Its
function is to maintain steering control in
braking.  You  shall  always  keep  safe
distance away from other vehicles.
ABS cannot prevent skidding caused by
sudden  change  of  vehicle  direction,
such  as  sharp  turning  or  sudden  lane
changing.    Drive  the  car  carefully  at
safe  speed  regardless  of  the  road  and
weather conditions.
ABS cannot prevent reduction in vehicle
stability.  In  hard  braking,  the  steering
shall be moderate. Sharp turn in driving
may  cause  the  car  to  smash  into  the
traffic  flow  in  the  opposite  direction  or
rush off the road.
On  soft or rugged  road  (such  as sandy
or snowy road), a vehicle with ABS may
need  longer  braking  distance  than  a
vehicle

without

ABS.

Under

this

condition, you shall slow down the car
while keeping larger distance from other
vehicles.

Front

-------------------------------------------------------------------------------------------------------------------------------------------------------------

BYD G3 AUTO Owner’s Manual

ABS Indicator

ABS  has  self-detection  function.  If  any
fault, ABS indicator (refer to introduction
on  combination  instrument)  on  the
instrument panel  will  be turned on. This
means  ABS  function  of  the  brake
system has fault. But the brake can still
provide  normal  braking  force  like  an
auto  without  ABS  function.  Please
contact  BYD  service  station  to  check
you car.

If  ABS  indicator  and  braking  system
indicator are turned on at the same time
when hand brake is released completely,
it  means  the  braking  force  distribution
system also fails.
Press brake pedal slightly to check if it is
normal; if normal, check the braking fluid
level  when refilling fuel at  the  next time
(refer  to  section  on  checking  braking
fluid). If the level is low, drive your car to
BYD  service  station  to  check  whether
brake  system  has  leakage  and  check
the brake wearing piece.

If  the  brake  pedal  feels  abnormal,  you
shall take measures immediately. As the
brake  system  adopts  dual  loop  design,
even if part of the system fails, you can
still  control  braking  of  the  other  two
wheels.  But  at  this  time  you  shall  step
the brake pedal deeper to brake the car,
and the brake distance will be longer.

Shift to lower gear to slow down the car,
and  park  the  car  at  roadside.  As  the
braking  distance  is  longer,  driving  the
car  under  this  condition  is  dangerous.
You shall have the car towed away and
repaired as soon as possible.
If  you  have  to  drive  the  car  for  a  short
trip, you must drive with extremely car.

Drive in Poor Weather

Driving  force  (adhesive  force)  and
visibility  will reduce in rainy, snowy and
fog  days,  and  such  environment
requires  different  driving  skill.  Make
good  maintenance  of  the  car  in  normal
time, and take special care when driving
in poor weather. Under such conditions,
do  not  use  cruise  control  function
(optional on some models).
Driving  skill

– driving speed shall be

slower  than  in  dry  weather.  Even  when
the  road  is  a  little  damp,  the  car  need
much  longer  response  time  to  apply
stable  and  even  pressure  to  all  control
devices. In wet weather, sharp turning or
hard  braking  may  cause  the  car  out  of
control. In the first a few miles after the
road condition  changes,  you shall  drive
with  special  care,  especially  in  winter
days.  During  summer,  a  driver  may
forget driving skills for driving on snowy
road,  and  exercise  is  needed  to  regain
such skills.
After  long  dry  period,  you  shall  be
careful  when  driving  in  rainy  days.    In
the first rainy days after long dry period,
oil  on  the  road  will  float  on  the  top  of
water, making the road slippery.
Visibility

– under all weather conditions,

it  is  very  important  for  a  driver  to  see
around and  to be seen by other drivers
clearly.  In  poor  weather,  visibility  will

deteriorate  and  you  shall  turn  on
headlights  even  in  daytime  for  better
visibility.
You  shall  check  the  windshield  wiper
and  cleaner  regularly.  Keep  sufficient
cleanser  liquid  in  the  cleanser  tank  of
windshield cleaner. If the  wiper can not
wipe  the  windshield  clean,  you  shall
replace the wiper blade. In addition, you
can  use  defroster  and  AC  device  to
prevent  fogging  on  the  internal  side  of
the windows.

Driving  force  (adhesive  force)

– you

shall  check  whether  the  wear  and
pressure  of  the  tires  are  appropriate
regularly,  which  is  important  to  prevent
the  auto  shift  (adhesive  force  reduced
on wet road). In winter all 4 wheels shall
change  to  snow  tires  (with  deep
anti-skidding

tread)

for

optimum

operation performance.

In

driving

you

shall

check

the

ever-changing  road  conditions.  Damp
leaves  my  be  as  slippery  as  snow,
―Clean‖  road  may  be  covered  with  thin
ice. When the environment temperature
is  near  freezing  point,  driving  is  very
dangerous as the road may be covered
by  water  and  ice  alternatively.  As  a
result, the adhesive force may change a

lot suddenly.
When downshift, take special care. If the
adhesive force is low, the driving wheels
may  be  locked  up  for  an  instant,  which
may also cause skidding.

In  overtaking  or  being  overtaken,  take
special as the water fog splashed up by
large  vehicle  may  block  you  view  and
the  air  shock  wave  caused  by  large
vehicle may lead to losing control of the
car.
Note: do not drive on a road under deep
water,  which  may  cause  damage  or
failure of engine and electrical system.

Engine Fault Indicator

This  indicator  will  be  on  for  several
seconds when turning the ignition switch
to  ON  (II).  If  it  turned  on  at  any  other
time,  it  means  some  emission  control
device  in  the  engine  system  has  fault.
Even if you cannot feel obvious change
