information below before driving your 
vehicle.

Wear your seat belt every time when 
you drive
 A seat belt is your best protection in 

all types of collisions, Airbags are only 
designed to supplement seat belts 
and can’t supersede the seat belt. So 
ensure that you and your passengers 
always wear seat belts properly.
Restrain all children 
The children who are below 12 years 
should be restrained in back seat. 
Infant and little children should be

should use a booster seat and a 
shoulder belt until they can use the belt 
properly without a booster seat.
Beware of airbags hazard
While  airbags  can  protect  you  in 
collisions, they also will cause serious 
or fatal injuries to people who do not 
operate properly, such as sit too close 
to the airbags, or who are not properly 
restrained. Therefore, Ensure to follow 
all instructions and warning in this 
manual.

Control your speed 
Excessive  speed  is  major  factor  in 
crash injuries and may lead up to 
death. Generally, the higher the speed 
always leads to the larger risk. Never 
drive faster than the speed is safe for 
current conditions, regardless of the 
maximum speed posted.
No Drunk Driving

or other activities that keep you from 
paying close attention to the road, 
other vehicle and pedestrians may 
cause a crash. Remember, situations 
can  change  quickly,  and  only  you 
can decide when it is safe to divert 
attention away from driving.

Introduction about BYD 

F3DM System

BYD  F3DM  (Dual  Mode) 

System: 

It is combined petrol engine with 
electric engine, BYD F3DM is able 
to drive by electric engine or petrol 
engine.  

Features of BYD DM System: 

Compared with common gasoline 
vehicle, BYD DM system has a better 
power performance, which can improve 
fuel economy in HEV mode.  In EV 
mode, BYD F3DM will run 

with low noise and zero emission, In 
addition, F3DM equipped with recycle 
electric motor assistance braking 
energy, which can recycle and convert 
the  kinetic  energy  lost  in  braking  to               
electrical energy and store it in power 
battery. The electrical energy can be 
used later. 

Compared with other hybrid electrical 
cars, BYD F3DM has a power battery 
with large capacity, which can increase 
the  driving  range  greatly  under  EV 
mode. F3DM can be charged with 180-
240V AC, which is convenient for you 
to charge your vehicle. You will not rely 
on gasoline anymore if your F3DM can 
be charged in certain drive range in 
time.

Work Mode of BYD DM 

System: 

1. “EV” – EV mode: 
Under  EV  mode,  power  battery 
provides electrical energy to electric 
motor power 2 for driving car. 

2. “HEV” – HEV mode: 
(1) HEV mode A: The engine reaches 
its best working condition and directly 
drives the car, and the electric motor 
power 1 runs with the petrol engine to 
charge the power battery.

F3DM Owner’s Manual

(2) HEV mode B: The petrol engine 
and electric motor power work together 
to drive the vehicle, which provides a 
higher output power. 

(3) HEV mode C: When a lower power 
output required by overall unit, turn 
to the HEV mode, the engine drives 
electric motor power 1 to generate 
electricity for the electric motor power 
2 to drive the car and the spare 
electricity will be stored in the power 
battery.
