Driving preparation

You  should  do  the  following  checks  and
adjustments before you drive your vehicle:

1.  Make  sure  all  windows,  mirrors  and
outside  lights  are  clean  and  unobstructed.
Remove  frost,  snow  and  ice  stockpiling
above.
2.  Check  that  the  hood  and  the  trunk  are
fully closed.
3. Visually check the status of the tires. If a
tire  looks  slow,  check  its  pressure  using  a
gauge.
4.  Check  that  any  items  you  may  be
carrying are  stored  properly or fasten down
securely.
5.  Check the  seat  adjustment  (refer  to  42nd
page).
6.  Check  the  adjustment  of  inside  and
outside mirrors (refer to 86th page).
7.  Check  the  steering  wheel  adjustment
(refer to 35th page).
8.  Make  sure  the  doors  are  securely  closed
and locked.
9.  Fasten  your  seat  belt.  Check  that  your
passengers  have  fastened  their  seat  belts
(refer to 6th page).

10.  Turn  the  ignition  switch  to  the  position
of  ON  (Ⅱ), and check the indicators in  the
instrument panel.

11. Start the engine (refer to 86th page).

12.  Check  the  gauges  and  indicators  in  the
instrument panel (refer to 24th page).

Start engine

1. Apply the parking brake.

2.  In  cold  weather,  turn  off  all  electrical
accessories  to  reduce  the  consumption  of
the battery.

3. Instruction transmission:
Make  sure  the  shift  lever  is  in  neutral.  If  it
isn‘t,  press  down  the  clutch  pedal,  and
change  the  transmission  shift  lever  to
neutral, press down the brake pedal.

Automatic transmission/CVT transmission
Make sure the shift lever is in park (P) or in
neutral (N), press down the brake pedal.

4. Turn the  ignition  key to  the  START  (III)
position  at  the  condition  of  not  pressing
down  the  accelerator  pedal.  If  the  engine
doesn‘t  start  right  away,  turn  the  key  away
from the START (III) position in 15 seconds,
and pause for at least 10 seconds before try
again.

5.  If  the  engine  doesn‘t  start  within  15
seconds,  or  starts  but  stalls  right  away,
repeat  step  4  with  the  accelerator  pedal
pressed  halfway  down.  If  the  engine  starts,
leave the foot from the accelerator pedal, so
the engine does not race in high speed.

6.  If  the  engine  still  doesn‘t  start,  press  the
accelerator  pedal  down  to  the  bottom  and
hold  it there in the  ignition process to clear
flooding. Do as it says before, the time that
the  key  pauses on  the  START  (III)  position
doesn‘t  exceed  15  seconds.  If  the  engine
still  doesn‘t  start,  repeat  step  5.  After
starting  the  engine,  leave  the  feet  from  the
accelerator  pedal,  so  the  engine  does  not
race in high speed.

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

BYD AUTO F6 OWNER’S MANUAL

Start in high altitude (>2400m)
cold weather

The  engine  is  hard  to  start  in  cold  weather.
Also, the engine is more hard to start in the
thinner  air  found  at  altitudes  above  2,400
meters.
At  this  time,  you  should  take  following
steps:
1.  Turn  off  all  electrical  accessories  to
reduce the consumption of the battery.
2. Press the accelerator pedal halfway down,
and  hold  it  there  in  the  whole  process.  The
time that the key pauses on the START (III)
position do not exceed 15 seconds. After the
engine  starts,  you  should  release  the
accelerator  pedal  slowly  when  the  engine
speed  accelerates  and  engine  running  goes
stability.
3. If the engine doesn‘t start after doing step
2,  press  the  accelerator  pedal  down  to  the
bottom  and  hold  it  there,  try  to  start  the
engine  in  15  seconds  again.  If  the  engine
still doesn‘t start, repeat step 2.
If  the  temperature  out  of  vehicle  is  below
centigrade  zero,  or  your  vehicle  has  parked
for  several  days  without  being  driven,
preheat  the  engine  several  minutes  before
driving.

Instruction transmission

To  run  stably,  instruction  transmission  all  has
synchronizer on all of driving gear. Instruction
transmission  has  locking  device,  to  avoid
shifting  gear  from  the  fifth  gear  to  reverse
gear  directly.  When  shifting  gear, you  must
tread the clutch pedal down to bottom.
When not shifting gear, don‘t put you feet
on the clutch pedal, or it can accelerate the
abrasion of clutch.

Only  after  stopping  the  vehicle  completely,
you may shift to reverse gear. If you shift to
reverse  gear  when  the  vehicle  doesn‘t  stop
completely, it will damage the transmission.
After  treading  down  the  clutch  pedal,  and
before  shifting  to  reverse  gear,  you  should
stop  a  few  seconds,  or  shift  to  one  driving
gear  and  stop  for  a  moment.  In  this  way,  it
will  make  the  gear  stop  running,  and  avoid
―milling‖ each other.

When

decelerating,

obtain

additional

braking force from the engine by the way of
downshifting.  The  additional  braking  force
is  helpful  to  keep  one  safety  speed,  when
driving  down  the  ramp;  it  can  prevent  the
braking

system

overheating.

Before

downshifting, you need to ensure that the
engine speed display doesn‘t enter in the red
area of tachometer. Please see the max
permissible speedometer.

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

BYD AUTO F6 OWNER’S MANUAL

Friendly tips

When  driving  on  the  slippery  road,
rapid  acceleration  or  rapid  deceleration
both  can  cause  the  vehicle  out  of
control.  Once  when  having  a  car
collision accident, it will cause injury to
you.
You  should  be  more  careful  when
driving on slippery road.

When  driving  at  the  highest  gear,  it  can
make  engine  run  stably  and  accelerate.  It
can  not  only  save  fuel  furthest,  but  also
control  exhaust  emission  most  effectively.
We commend the gear point as following:

Up shifting

The speed when

shifting gear

1 gear→2 gear
2 gear→3 gear
3 gear→4 gear
4 gear→5 gear

25 km/h
40 km/h
65 km/h
80 km/h

Max. permissible speed

These

speeds

correspond

max.

permissible  speed  of  every  gear.  If  exceed
these  speeds,  the  engine  speed  display  will
enter  into  red  area  of  tachometer.  If  this
happens,  you  will  feel  the  engine  running
intermittently,  this  is  caused  by  safety
governor  in  the  ECU  control  device  of
engine.  When  you  let  the  engine  speed
reduce  below  red  area,  the  engine  will
recover normal running.

Before downshifting, you need to ensure the
speed  can  not  exceed  the  max.  permissible
speed of lower gear (see right table), and to
avoid damaging the engine.

Automatic transmission

The  gearbox  of  your  BYD  F6  is
instruction/automatic  transaxle;  it  has  four
forward gears, and electronic control system,
so  it  can  shift  gear  stably.  It  also  has
―lock-up  type‖  torque  converter,  to  save
more  fuel.  When  the  torque  converter  is
locked  up,  you  will  feel  like  using  another
gear.

Shift lever position indicator

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

BYD AUTO F6 OWNER’S MANUAL

Gear  indicator  is  located  on  the  left  lower
side of tachometer, show which position the
shift  lever  is  in  (P,  R,  N,  D;  when  it  is  in
instruction  model  and  has  speed,  it  can  show
the current using gear 1M, 2 M, 3 M, 4.

Position of shift lever

Shift lever includes two models, instruction and
automatic.  The  automatic  model  has  four
gears.  When  start  the  engine,  shift  lever
must  be  in  the  position  of  Park  (P)  or
Neutral  (N).  When  you  stop  the  vehicle  in
the position of D, N or R, you must press on
the  brake  pedal  hardly,  and  have  your  foot
off the accelerator pedal.

P：Park—this  position,  mechanically  locks
the  transmission.  Use  Park  whenever  you
are  turning  off  or  starting  the  engine.  To
shift  out  of  Park,  the  key  should  be  in  the
position  of  ignition  switch  ON  (Ⅱ),  and
press on the brake pedal and have your foot
off  the  accelerator  pedal.  Press  the  release
button on the bottom of shift lever, you can
shift out of it.

You  must  also  press  the  release  button  to
shift  into  Park.  To  avoid  damaging  the
transmission,  come  to  a  complete  stop
before shifting into Park.

R：Reverse—about the operation method of
shifting from Park to Reverse, please see the
explanation of Park. When shifting from
Neutral to reverse, come to a complete stop
and then shift. Before shifting from Neutral
to Reverse, press the release button.

N：Neutral—use Neutral if you need to
restart a stalled engine, or if it is necessary

to stop briefly with the engine idling.
Shift  to  the  Park  position  if  you  need  to
leave your vehicle. Press on the brake pedal
when  you  are  moving  the  shift  lever  from
Neutral to another gear.

D：Drive—use  this  gear  for  your  normal
driving.  The  transmission  automatically
selects suitable gear according to the vehicle
speed  and  acceleration.  You  may  feel  the
transmission  shifting  up  at  higher  speed
when  the  engine  is  cold.  This  helps  the
engine warm up faster.

When  the  shift  lever  is  in  the  position  of
Drive, move the lever to right side (assistant
driver  direction),  so  the  shift  lever  is
shifting  into  instruction  model  from  automatic
model.  You  can  push  the  shift  lever  to  two
gears,  upshifting  (+)  and  downshifting  (-)
under  the  manual  model,  so  that  you  can
control the transmission gear by hand.

Upshifting (+)—when normal driving and
the shift lever are in the instruction model, push
the shift lever to this gear. After the control
module of power assembly is able to judge
according

the

speed

status,

the

transmission gear will correspond to

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

BYD AUTO F6 OWNER’S MANUAL

increase until the transmission is in the
hightest gear.

Downshifting (-)—when normal driving and
the shift lever is in the instruction model, push
the shift lever to this gear. After the control
module of power assembly is able to judge
according

the

speed

status,

the

transmission gear will correspond to
decrease until the transmission is in the
lowest gear.

When parking, make sure to use hand brake.
The  indicator  on  instrument  panel  only
shows  that  the  hand  brake  isn‘t  released
completely,  but  doesn‘t  show  that  the  hand
brake  has  been  pulled  indeed.  You  must
make sure to pull the hand brake; otherwise,
the vehicle may roll when it is parked on an
incline.

If

your

vehicle

installs

automatic

transmission, you should set the hand brake
firmly  before  shifting  the  transmission  into
Park. This can avoid vehicle moving, so that
press  on  the  Park  mechanism  in  the
transmission—in  this  way,  when  you  want
to  drive,  it  can  make  the  shift  lever  to  shift
out of Park more easily.

Parking notice

1  Make  sure  that  the  roof  window  (limit  to
some  vehicle  type)  and  windows  are  all
closed well.

2 Turn off the lights.

3 Place any packages, valuables, etc., in the
trunk or take them with you.

4 Lock the doors with the key or the remote
transmitter,  check  the  trunk  whether  it  is
locked up.
Check the indicator on the instrument panel
to ensure that the security system is set.

5  Never  park  over  dryleaves,  tall  grass,  or
other  flammable  materials.  The  hot  three
way catalytic could cause these materials to
catch on fire.

6  When  parking,  if  the  vehicle  is  facing
uphill,  turn  the  front  wheels  away  from  the
curb.  If  the  vehicle  installs  instruction
transmission, shift it into the first gear.

7  When  parking,  if  the  vehicle  is  facing
downhill,  turn  the  front  wheels  toward  the

curb.  If  the  vehicle  installs  instruction
transmission, shift it into Reverse.

8  Make  sure  the  hand  brake  whether  it  is
fully  released  before  driving  away.  Driving
with  the  hand  brake  partially  set  can
overheat or damage the rear brake.

9  Make  sure  the  hand  brake  whether  it  is
fully  released  before  driving  away.  Driving
with  the  hand  brake  partially  set  can
overheat or damage the rear brake.

How to Drive Economically

Select  ―D‖  when  driving  on  the  wide  road.
Slowly  step  down  the  accelerator  to  assure
the  auto  gear  changes  when  the  engine
speed is relatively slow.

Acceleration and Overtaking

Step down the accelerator to the bottom
quickly, which will activate the low-gear
shift to switch to a proper gear.

Special Environment

If you drive on the curve or mountain road,
you are suggested to use instruction mode
instead of auto mode.

In Cold Weather

After starting the engine, you shall wait for
a few seconds before switching the gear
shift lever from position P to position D or
R to avoid stopping the engine.

Faults

If  the  warning  light  for  ―transmission  case
fault‖ and ―service‖ on the instrument panel
is  on  when  driving,  it  indicates  a  fault
occurs.
Contact  the  BYD  service  shops  as  soon  as
possible.

Adaptive Update of the Clutch

In  all  these  following  cases,  you  must
perform adaptive update for the clutch.
1 TCU program is refreshed
2 Replace with a new TCU
3 Replace with a new transmission box
The  adaptive  program  of  clutch  is  as
follows:
1 Start the engine
2 Step on the brake (keep stepping down in
the whole process)
3 Put the gear on N
4 Stay for 5 seconds
5 Put the gear on D
6 Stay for 5 seconds
7 Put the gear on N
8 Stay for 5 seconds
9 Put the gear on R
10 Stay for 5 seconds

Repeat the 3 to 10 steps mentioned above
three times.

Brake system
Brake system design

The hydraulic system of drive brake has two
separate  circuits.  Each  circuit  works
diagonally  across  the  vehicle  (the  left-front
brake is connected with the right-rear brake,
etc.).  If  one  circuit  has  problem,  you  will
still have braking at two wheels.

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

BYD AUTO F6 OWNER’S MANUAL

ABS

ABS helps prevent the wheels from locking
up or slipping when braking rapidly, so that
make you retain steering control.

When the front wheels are slipping, you will
not  do  steering  control,  in  other  words,
although turn the steering wheel, the vehicle
still  runs  directly.  ABS  helps  prevent  from
locking

up,

and

because

rapidly

pulsatile-typed  brake  is  quicker  than
person‘s  reaction,  it  is  helpful  to  retain
steering control.

ABS also balances the front-to-rear braking
distribution according to vehicle loading.

Don‘t  pumping  press  on  the  brake  pedal,
otherwise,  it  will  let  the  ABS  shut  down.
When  steering  away  from  the  hazard,  you
should always keep firm, steady pressure on
the  brake  pedal,  in  order  to  let  the  ABS
activate.  This  is  sometimes  referred  to  as
―stomp and steer‖.

When  the  ABS  activates,  you  will  feel  a
pulsation in the brake pedal, and hear some
noise.  This is  normal, it  is  the ABS  rapidly
pumping braking.

The speed of ABS activating depends on the
size  of  wheels‘  driving  force  (adhesive
force).  On  dry  pavement,  you  will  need  to
press  on  the  brake  pedal  very  hard  before
the  ABS  activate.  However,  you  will  feel
the  ABS  activate  immediately  if  you  are
trying to stop on the snow or ice.

Important safety reminders
ABS  does  not  reduce  the  time  or  distance,
which  takes  to  stop  the  vehicle.  This
installation  only  helps  you  control  steering
during  braking.  You  should  always  keep  a
safe distance away from other vehicles.

ABS  will  not  prevent  slipping  those  results
from  changing  direction  abruptly,  such  as
trying to take a corner too fast or making a
sudden  land  changing.  Always  drive  at  a
safe  speed  for  the  road  and  weather
conditions.

ABS  can  not  prevent  a  loss  of  stability.
Always steer moderately when sudden hard
braking.  Severe  or  sharp  steering  wheel
movement  can  still  cause  your  vehicle  to
veer into oncoming traffic or off the road.

A  vehicle  with  ABS  may  require  a  longer
distance to stop on loose or uneven surfaces
(such  as  gravel  or  snow  surfaces)  than  a
vehicle  without  ABS.  Under  this  condition,
slow  down  the  speed,  and  keep  a  greater
distance away from other vehicles.

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

BYD AUTO F6 OWNER’S MANUAL

ABS indicator

ABS  has  the  self-diagnosis  function.  If
malfunction  happens,  the  ABS  indicator
(refer  to

page) on instrument panel

comes on. This means that the ABS function
of  braking  system  has  shut  down.  At  this
time,  the  brakes  still  supply  common
braking  ability  like  a  conventional  vehicle
without  ABS.  You  should  have  BYD
authorized  service  station  to  inspect  your
vehicle as soon as possible.
If the ABS indicator and the braking system
indicator  come  on  together,  and  the  hand
brake  is  fully  released,  it  means  that  the
front-to-rear  braking  distribution  system
may also be shut down.

Inspect  the  brakes  according  to  the
explanation  on  page  91.  If  the  brakes  feel
normal,  you  should  drive  slowly,  and  have
your  vehicle  repaired  by  BYD  authorized
service  station.  At  this  time,  avoid  sudden
hard  braking  which  could  cause  the  rear
wheels to lock up and possibly lead to a loss
of control.

Driving in atrocious weather

Because  the  decrease  of  driving  force
(adhesive  force)  and  visibility,  different
environments such as rain day,  fog day and
snow  weather  needs  different  driving  skill.
Maintain  the  vehicle  well  at  any  time.  You
need  to  be  more  careful  when  you  have  to
drive  in  atrocious  weather.  You  should  not
use the speed-fixed cruising control (limit to
some vehicle type) under these conditions.

Driving  skill—the  speed  driving  in  wet
weather  is  slower  than  in  the  dry  weather.
Your vehicle also needs longer time to react,
put  stable  and  uniform  pressure  on  all  the
control  installations,  even  if  it  is  under  the
condition  which  looks  like  a  little  wet.  In
the  wet  weather,  sharp  steering  or  sudden
hard braking, both possibly lead to a loss of
control.  You  must  be  more  careful  in  the
first  a  few  kilometers  that  you  adopt  the
changing of driving conditions, especially in
the  snow  weather.  One  driving  person
maybe forget the driving skills on the snow
surface in the several months of summer, he
(she)  needs  to  master  these  skills  anew
through practicing.

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

BYD AUTO F6 OWNER’S MANUAL

When  driving  in  the  rain  weather  after
long-term  drought,  you  should  be  more
careful.  The  first  rain  after  long-term
drought will make the oil plants float on the
pavement,  and  lead  to  pavement  wet  and
slip.

Visibility—under all the weather conditions,
it  is  very  important  to  see  far  and  near
clearly,  and  be  saw  by  other  drivers.  It  is
more  difficult  to  do  this  point  in  the
atrocious  weather.  To  be  seen  more  clearly,
you  should  turn  on  the  head  light  in
daytime.

You  should  often  inspect  the  windshield
wiper  and  washer.  Keep  storing  proper  and
enough washer fluid in fluid reserve tank of
windshield  washer.  If  the  wiper  does  not
scrape  the  water  cleanly  or  leave  the  stripe
on  the  windshield,  replace  the  blade.
Otherwise,  use  the  frost  removal  and
air-condition  to  make  window  inside
without fog (refer to 35

page).

Driving force (adhesive force)—you should
often inspect the abrasion status of tires and
the pressure of tire whether it is suitable, the
two items are very important to prevent the

―drafting  phenomenon‖  (a  loss  of  adhesive
on wet pavement) of vehicle. In winter, four
wheels  should  be  installed  snow  tires
(antiskid deep strain), to obtain best control
capability.

You  should  look  round  the  illusive  road
status.  Dry  leaves  maybe  slip  like  ice  and
snow. ―Clean‖ pavement may have thin ice.
When the temperature out of vehicle is near
to zero degree, the driving condition may be
very  dangerous  and  the  pavement  may  be
covered  by  water  and  ice.  So  the  adhesive
force  of  vehicle  may  sudden  change  under
the condition without any threaten.

When downshifting, you should take care
doubling. If the adhesive force is low, the
driving wheel may be locked up a moment,
this may lead to slip.

When  overtaking  or  being  overtook,  you
should  be  very  careful,  because  the  water
fog  which  is  caused  by  heavy  vehicle
maybe  have  a  influence  on  your  sight,  and
air  wave  impact  maybe  lead  to  a  loss  of
control.

Trailer

Towing a trailer is not designed on your
vehicle. Try to install a bar on your vehicle,
but it maybe damage the chassis badly.

Friendly tips

Don‘t  drive  on  the  pavement  of  deep
water. It is easy to cause malfunction or
damage  to  engine  and  electronic
equipment.

Maintenance

Periodical  maintenance  is  the  best  method
to  protect  vehicle,  it  can  make  you  drive
more  safety,  more  economy,  and  no
