Notes of Do-it-yourself maintenance
In case of doing maintenance by 
yourself, be sure to follow the correct 
procedures in this section. 
Please note that incorrect or 
incomplete maintenance may result in 
operating problems. 
This section makes explanations only 
on maintenance operations that are 
relatively easy to do on your own. 
As said in chapter 6, there are still a 
number of items that must be done 
by a qualified technician with special 
tools.
Utmost attention should be paid to 
avoiding accidental injuries when 
working on your vehicle. Precautions 
below should be especially careful to 
observe.

Warning

When the DM system is operating 
with the “OK” indicator on, the 
engine is automatically started in 
some case. When you inspect the 
engine compartment, be sure to 
press the “POWER” switch to the 
“OFF” mode.
Keep your hands, clothes and 
tools away from the moving fans 
and drive belt of engine, when the 
engine is on(You’d better tie up long 
hair and remove accessories such 
as finger ring, watch, necktie and so 
on to avoid any injury.) 

 

y

Engine compartment —engine, 

radiator, exhaust pipe, hold-up 
vessel of power steering fluid and 
spark plug cover— will be hot 
after driving. Do not touch them, 
as it may cause burns. The

and spark plug may also be very 
high 

 

y

If the engine is very hot, do not 

remove the radiator cover or 
screw off the drain plug to avoid 
burning yourself. 

 

y

Do not leave any flammable 

material in the engine 
compartment such as paper and 
cloth. 

 

y

Be sure that the DM system is 

in the “OFF” mode if you work 
near the electric cooling fans or 
radiator grille. With the ignition 
on, the electric cooling fans will 
automatically start to run if the 
engine coolant temperature is 
high and/ or the air conditioning 
is on.

 

y

Handle the storage battery with 

special care, as it contains 
poisonous gas and corrosive 
sulfuric acid.

 

y

Use eye protection whenever you 

work on or under your vehicle 
where you may be exposed to 
flying or falling material, fluid 
spray, etc.

 

y

U s e d   e n g i n e   o i l   c o n t a i n s 

potentially harmful pollutants, 
which may cause skin disorders   
such as skin inflammation or skin 
cancer,  so care should be taken 
to avoid prolonged and repeated 
contact with it. To remove used 
engine oil from your skin, wash 
thoroughly with soap and water.

 

y

Do not leave used oil within the 

reach of the children.

 

y

Dispose of used oil and filter only 

in a safe and acceptable manner. 

Do not dispose of used oil and 
filter in household trash, in sewer 
or onto the ground. Refer to BYD 
authorized service station for 
recycling or disposing methods.

 

y

Take care when filling the brake 

fluid reservoir because fluid can 
harm your eyes and damage 
painted surfaces. If fluid gets in 
your eyes, flush your eyes with 
clean water immediately. If you 
still feel uncomfortable with your 
eyes, go to the doctor.

 

y

Basic check is needed before 

driving, or it may cause an 
accident.

 

y

If the maintenance is not applied 

or properly applied, it may cause 
serious damage to you and your 
vehicle.

vehicle is on level ground and preheat 
the engine. Wait several minutes after 
shutting down the engine. 
Pull the dipstick out, place a piece of 
fabric at its end and wipe it clean.
Insert the dipstick again, push it in as 
far as it will go, or the reading will not 
be correct. 
Pull the dipstick out and look at the oil 
level while holding a rag under the end.

WARNING

Be careful not to touch the hot 
exhaust manifold.

NOTICE

Be careful not to drop the engine oil 
on the vehicle components.

If the oil level is below or little higher 
than the lower hole, add oil of the 
same type as already in the engine.
Remove the engine oil fill cap and 
add engine oil in small quantities at a 
time, checking the dipstick. You are 
recommended to use a funnel when 
adding oil. 
If the oil level is between the lower and 
upper holes, the oil level is acceptable.
When  the  level  reaches  within  the 

correct range, install the fill cap hand-
tight.
Oil quantity, L (qt.,lmp.qt.):

F3DM Owner’s Manual

Look at the transparent antifreeze fluid 
tank when the engine is cold to see 
if it is between the “MAX” and “MIN” 
lines on the tank. If the level is low, 
add antifreeze fluid. (For the antifreeze 
fluid type, see “Antifreeze fluid type 
selection” described below.)
The antifreeze fluid level in the tank 
will vary with the temperature of the 
engine. However, if the fluid level is on 
or below the “MIN” line, add antifreeze 
fluid. Bring the level up to the “MAX” 
line. 
If the antifreeze fluid level drops within 
a short time after replenishing, , there 
may be a leak  in the system. Visually 
check to the radiator, hoses, radiator 
cap, drain cock and water pump.
If you couldn’t find any leak, have your 
BYD authorized dealer test the cap 
pressure and check for leaks in cooling 
system.

WARNING

To avoid personal injury, if the steam 
comes out from the front hatch, do 
not open it before the steam to be 
dissipated.
To prevent burning yourself, do 
not remove the radiator cap when 
engine is hot.

Antifreeze fluid type selection
Only use antifreeze authorized by 
BYD authorized dealer. Choose and 
add suitable type of antifreeze fluid 
into cooling system according to 
environment temperature.
Use of improper antifreeze fluid may 
damage your engine system. 

NOTICE

Do not use plain water alone, which 
may cause damage on engine 
cooling system.

Please contact BYD authorized dealer 
for further details.

Check Radiator and 

Condenser 

If any of the above parts are extremely 
dirty or you are not sure of their 
condition, take your vehicle to BYD 
authorized dealer.

WARNING

To prevent burning yourself, be 
careful not to touch radiator or 
condenser when the engine is hot.
Do not operate by yourself to avoid 
damaging the radiator or condenser.

Check Tire Inflation Pressure 

Keep your tire inflation pressures at the 
proper level.
For information on recommended 
cold tire inflation pressure and tire 
dimension, please refer to Chapter 8.

WARNING

The tire inflation pressure is 230 
kpa while the spare tire inflation 
pressure shall be 420 kpa.

You should check the tire inflation 
pressure every two weeks, or at least 
once a month. And do not forget the 
spare.
Improper tire pressure may increase 
gas consumption, reduce driving 
comfort and tire service life, and pose 
danger to road safety. 
If the tire need air filling frequently, 
please contact BYD authorized dealer 
for a check. 

WARNING

Keep your tires properly inflated. 
Otherwise, the following conditions 
may occur and cause an accident 
resulting in serious injuries.

F3DM Owner’s Manual

The following instructions for checking 
tire inflation pressure should be 
observed: 
●Check tire pressure only when the tire 
is cold. If the vehicle has been parked 
for at least 3 hours and has not been 
driven for more than 1.5km or 1 mile 
since, you will get an accurate cold tire 
inflation pressure reading.
●Tire inflation pressure gauge must be 
used. The appearance of a tire can be 
misleading. In addition, a few pounds’ 
difference may degrade ride and 
handling.
●Do not bleed or reduce tire inflation 
pressure after driving. It is normal for  
the tire inflation pressure to be higher 
after driving. 
●Make sure valve cock is installed on 
tire. It blocks dust, damp from entering 
tire and prevent air leakage. Install a 
new one if it lost.

Check and Replace Tire

Tire Tread wear indicator

Check Tire 
Check the tire tread for tire wear 
indicator. If the wear indicator is visible, 
the tire shall be replaced.
The tire on your BYD F3DM has built- 
in tread wear indicators to help you 
know when the tires need replacement. 
When the tread depth wears to 1.6mm 
(0.06in.)  or  less,  the  indicators  will 
appear. If you can see the indicators in 
two or more adjacent grooves, the tire 
shall be replaced. The lower the tread, 
the higher the risk of skidding.  
The snow tires will be useless if the 

tread wears down below 4mm (0.16 
in.).
If there were tire damage such as cuts, 
splits, cracks deep enough to expose 
the fabric, or bulges indicating internal 
damage, the tire should be replaced. 
If a tire often goes flat or cannot be 
properly repaired due to the size or 
location of a cut or other damage, it 
should be replaced. If you are not sure, 
consult with BYD authorized dealer. 
If an air loss occurs while driving, do 
not continue driving with a deflated 
tire. Driving even a short distance can 
damage a tire beyond repair. 
Any tires which are over 6 years 
old  must  be  checked  by  a  qualified 
technician even if damage is not 
obvious. 
Tires deteriorate with age even if they 
have never or seldom been used.
This rule also applies to spare tires and

tires in storage. 

Replace Tires

When  replacing  a  tire,  only  use 
replacement tires and wheels that are 
of the same size, load index, speed 
rating and type as those originally by 
BYD.
U s e   o f   a n y   t i r e   o r   w h e e l   n o t 
recommended by BYD can affect 
the safety and performance of your 
vehicle, such as operability, passenger 
comfort, calibration of speedometer 
and odometer, ground clearance 
between the car body and tire or tire 
chains. 

WARNING

Please follow the instructions below, 
or an accident may occur resulting 
in serious injuries. 

 

y

Do not mix radial, bias belted, 

or bias-ply tires on your vehicle, 
as this may cause dangerous 
handling characteristics resulting 
in loss of control. 

 

y

Only use tires with size 

recommended by manufacturer’s ,or 
it may cause dangerous handling 
characteristics resulting in loss of 
control.

Never replace the tire on BYD F3DM 
with an used tire. 
Unknown tire may cause great danger.
You are recommended to replace four 
tires at one time, or at least both front 

or rear tires at the same time. 
See “If you have a flat tire” in Chapter 
4 for change procedure. 
Keep the wheels in balance when 
replacing tires. 
An unbalanced wheel may affect 
vehicle handling and tire life. Wheels 
can get out of balance with regular 
use and should therefore be balanced 
occasionally.

F3DM Owner’s Manual

Tire rotation diagram

Front

To equalize tire wear and extend its 
service life, you are recommended to 
rotate tire positions every 10,000 km. 
However, the most appropriate timing 
for tire rotation depends on driving 
habit and road surface conditions.

WARNING

●Do not include a spare tire when 
rotating the tires. 

When rotating tires, check for uneven 

wear and damage. Abnormal wear is 
usually caused by incorrect tire inflation 
pressure, improper wheel alignment, 
out-of-balance wheels, or severe 
braking.

Choose Tire Chain
Use the tire chains of correct size. 
Regulations regarding the use of tire 
chains vary according to location or 
type of road, so always check the local 
regulations before installing chains.
Install Tire Chain
Install the chains on the front tires 
as tightly as possible. Do not use tire 
chains on the rear tires. Retighten 
chains after driving 0.5-1.0 km(1/4-1/2 
mile).
When  installing  tire  chain,  carefully 
follow the instructions of the chain 
manufacturer 
If wheel covers are used, they will 

be scratched by the chain band, so 
remove the covers before putting on 
the chains.

WARNING

 

y

Do not exceed 50 km/h or 

the chain manufacturer’s 
recommended speed limit, 
whichever is lower.

 

y

Drive carefully avoiding bumps, 

holes, and sharp turns, which 
may cause the vehicle to bounce.

 

y

Avoid sharp turns or locked-wheel 

braking, as use of chains may 
adversely affect vehicle handling. 

 

y

W h e n   d r i v i n g   w i t h   c h a i n s 

installed, be sure to drive 
carefully. Slow down before 
entering curves to avoid losing 
control of the vehicle. Otherwise 
an accident may occur.
