Running-in period
Drive gently and avoid high speed.
Your vehicle does not need an elaborate
running in, but you can follow a few simple
tips below for the first 2000 km to save fuel
and prolong the service life of your vehicle:

Avoid full throttle acceleration when
starting and driving.

Avoid running the engine in over speed
mode.

Avoid sudden brakes for the first 300km.

Do not drive for a long time at any single
speed, either fast or slow.

Do not tow a trailer during the

first 2000km.

Fuel
Selecting the proper fuel is essential for

satisfactory engine performance.
It’s also important to pay attention to the
emission control and the maintenance of
relevant apparatus.
Engine damage caused by use of improper
fuels is not covered under BYD F3 warranty.
Fuel type
Only the GB17930-93# unleaded gasoline
can be applied.
In order to avoid the mistakes made by gas
station, there is a smaller opening in the fuel
box. The special muzzle of unleaded gasoline
pump is
well-matched with it, while the bigger
standard muzzle is unusable.

NOTICE

Do not use leaded gasoline on vehicle.
This may cause the three-way catalytic
converter to lose its effectiveness and
the emission control system to
function improperly. In addition, this
can increase the maintenance cost.
The vehicle emission system must
apply the GB17930-93# or above
unleaded gasoline.


If your engine has ignition knock
If you detect heavy ignition knock even when
using the recommended fuel, or if you hear
steady ignition
knocks while holding a steady speed on level

roads, consult your BYD AUTO service
station.
However, it is normal to hear brief and
slight knock when accelerating and
grabbling. Do not worry.

Fuel tank capacity: 50 L

Fuel cut-off system
When the engine stops running in an
accident, the engine control system will stop
providing engine with fuel in order to
minimize the possibility of fuel leak.

If the fuel pump stops working, please turn
the switch to “ACC” or “LOCK” before
restarting.

CAUTION

Before restarting the engine, check
the ground below your vehicle. If fuel
leaks to the ground, then the fuel
system would be damaged and need
repair. In this case, do not restart the
engine.

Three-way catalytic converter

The three-way catalytic converter is an
emission control device installed in the
exhaust system.
It aims to reduce pollutants in the exhaust
gas.

NOTICE

Keep people and combustible
materials away from the exhaust pipe
while the engine is running. The
exhaust gas is very hot.

Do not drive, idle, and park the vehicle
on easy-burning ground such as
lawn, leaves, sheets, and rags,
especially in summer.






NOTICE

A large amount of unburned gases

flowing in to the three-way catalytic

converter may cause or to overheat and

create a fire. To prevent this and other

damages, observe the followings

precautions:

● Use only the prescribed or above

unleaded gasoline.

● Do not drive with an extremely low

fuel level. Running out of fuel could

cause the engine to misfire, creating

an excessive load on the three-way

catalytic converter.

● Do not allow the engine to run at high

and low idle speed for a long time.

● Avoid running the engine in over

speed mode.

● Do not push-start or pull-start your

vehicle.

Do not turn off the ignition switch

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

F3/F3R OWNER’S MANUAL

- 132 -

Do not turn off the ignition switch
while the vehicle is moving.

Keep your engine in good running
condition. Malfunctions in the
engine electrical system,
electronic ignition
system/distributor ignition
system, or fuel system could
cause an extremely high three-way
catalytic converter temperature.

If the engine becomes difficult to
start or stalls frequently, take your
vehicle in for a check-up as soon
as possible.

To ensure that the three-way
catalytic converter and the entire
emission control system operate
properly, your vehicle must
receive the periodic inspections

required by your BYD AUTO
service station. For details, see
Section 6.

Engine exhaust cautions

CAUTION

Avoid inhaling the engine exhaust.

Make sure the exhaust system has

no holes or loose connections. The

system should be checked from

time to time. If you hit something, or

notice a change in the sound of the

exhaust, have the system checked

immediately.

Do not run the engine in a garage or

enclosed area except for the time

needed to drive the vehicle in or out.

The exhaust gases can not escape,

making this a particularly

dangerous situation.

Do not remain for a long time in a

parked vehicle with the engine

running. If it is unavoidable,

however, do so

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

only in an unconfined area and
adjust the heating or cooling system
to force outside air into the vehicle.

Keep the luggage component lid or
back door closed while driving. An
open or unsealed trunk lid or back
door may cause exhaust gases to
be drawn into the vehicle.

To allow proper operation of your
vehicle’s ventilation system, keep
the inlet grilles in front of the
windshield clear of snow, leaves, or
other obstructions.

If you smell exhaust fumes in the
vehicle, drive with the windows
open and the luggage component
lid or back door closed. Have the
cause immediately located and
corrected.


Facts about engine oil consumption
Functions of engine oil
Engine oil has the primary functions of
lubricating and cooling the inside of the
engine, and plays a major role in maintaining
the engine in proper working order.
Engine oil consumption
It is normal that an engine should consume
some engine oil during normal engine
operation. The causes of oil consumption in a
normal engine are as follows.

Oil is used to lubricate pistons,
piston rings, and cylinders.
A thin film
of oil is left on the cylinder wall when a
piston moves downwards in the cylinder.
High negative pressure generated sucks
some of this oil into the combustion
chamber when the

vehicle is decelerating. This oil as some
part of the oil film left on the cylinder wall

is burned by

the high temperature combustion gases
during the combustion process.

Oil is also used to lubricate the stems
of the intake valves.
Some of this oil is
sucked into the combustion chamber
together with the intake air and is
burned along with the fuel. High
temperature exhaust gases also burn
the oil used to lubricate the exhaust
valve stems.

The amount of engine oil consumed
depends on the viscosity of the oil, the
quality of the oil and the
conditions the vehicle is driven under.
More oil is consumed by high-speed driving
and frequent acceleration and deceleration.
A new engine consumes more oil, since its

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

F3/F3R OWNER’S MANUAL

- 134 -

pistons, piston rings and cylinder walls have
not become conditioned.

Oil consumption
:

Max. 1.0 L/1,000 km

When judging oil consumption, pay
attention to that it would be difficult to
judge the real oil level because oil
rarefies.

For example, if vehicle repeatedly drives for a
short distance, oil would be consumed. In this
case, even if the vehicle drives for 1,000 km
or above, oil level displayed on oil dip rod
would not decrease since oil has been
rarefied by fuel and smoke.
If vehicle drives at high speed (e.g. on
freeway), rarefied oil would ablate, so oil will
be over-consumed after high speed driving.

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

F3/F3R OWNER’S MANUAL

- 135 -

Importance of engine oil level check
One of the most important points in proper
vehicle maintenance is to keep the engine oil
at the optimum level so that oil function will
not be impaired. Therefore, it is essential that
the oil level be checked regularly. BYD AUTO
recommends that the oil level be checked
every time you refuel the vehicle.

NOTICE

Failure to check the oil level regularly
could lead to serious engine trouble
due to insufficient oil.


For detailed information on oil level check,
see “Checking the engine oil
level” in Section7-2.

Shift control

Manual transmission

To run smoothly, the manual transmission is
synchronized at all the drive gear, the manual
transmission is equipped with locking devices
so as not to directly shift from the 5 gear to
reverse. You should press clutch pedal to
end when shifting, not let your foot on the
clutch pedal, otherwise it will speed up the
clutch abrasion when no shift.
Shift to the Reverse only stopping the vehicle
completely. Shifting to
Reverse during driving will damage the
transmission. After pressing on the clutch
pedal, before shifting to reverse, should stay
a few seconds, or shift the drive gear on a

short stay. This will stop the gear to avoid mill
each other.
Slow down, under shift can obtain additional
braking force from the engine. This additional
braking force will help maintain a safe speed,
to prevent the brakes overheating in the
downhill.
Warning:
Fast accelerate and fast decelerate on the
slip road will cause the losing
control of vehicle. The event of a crash will
cause you injury. Should be extra carefully
driving at the slip road.
Automatic transmission

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

F3/F3R OWNER’S MANUAL

- 136 -

The automatic transmission of BYD F3 with 4
drive gear controlled by electronic control
system can shift stablely, equipped with
“lockup type” torque converter can reduce the
fuel consumption
Shift lever position indicators:

These indicators between the tachometer

and speedometer show which position the
shift lever is in.
The engine warning indicator will comes on if
the automatic transmission failure.
Shift lever position
The shift lever has 7 gears, when start the
engine, the shift lever should be the P or N
gear position. When you want to stop the
vehicle with the gear at d, 3, 2, L, N or R
position, you should forcibly step the brake
pedal, and get away from the accelerator
pedal
Park (P)—This position mechanically locks
the transmission. Use Park whenever you are
turning off or starting the engine. To shift out
of Park, you must press on the brake pedal
and have your foot off the accelerator pedal.

Press the release button on the front of the
shift lever to move it.
If you have done all of the above and still
cannot move the lever out of Park, see “Shift
Lock Release” on page .

You

must also press the release button to shift
into Park. To avoid transmission damage,
come to a complete stop before shifting into
Park. The shift lever must be in Park before
you can remove the key from

the ignition switch.
Reverse (R)—How to shift from Park to
Reverse refer to “Park”. Shift from the Neutral
to Reverse should after stop the vehicle
completely and should press the release
button.
Neutral (N)—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 and apply the parking brake. Press on
the brake pedal when you are moving the
shift lever from Neutral to another gear.

Drive (D)—Use this position for your normal
driving. The transmission automatically
selects a suitable gear for the vehicle speed

and acceleration. You may notice the
transmission shifting up at higher speeds
when the engine is cold. This helps the
engine warm up faster.
Drive (D3)—This position is similar to D,
except only the first three gears are selected
instead of all five. Use D3 when towing a
trailer in hilly terrain, or to provide engine
braking when going down a steep hill. D can
also keep the transmission from cycling
between third and fourth gears in stop-and-go
driving.
When at D3 and D, press the accelerator
pedal down to bottom can speed up quickly,
then the transmission will under shift
automatically. The transmission shift to First
or Second according to the speed of press
the accelerator pedal


Second (2)—To shift to Second, press the
release button on the front of the shift lever.
This position locks the transmission in
second gear, it will not shift to first gear
automatically. At the second gear, can
provide more power when climbing; increase
the engine braking when going down steep
hills, reduce the wheel spin when starting the
engine on a slippery
road or in deep snow.
First (L)—To shift from Second to First, press
the release button on the front of the shift
lever. This position locks the transmission in
first gear. By upshifting and downshifting
through 1, 2, D , and D, you can operate this
transmission

transmission without a clutch pedal.
Shift lock release
This allows you to move the shift slot. Lever
out of Park if the normal method of pushing
on the brake pedal and pressing the release
button does not work.
1.Stop the engine, pull up the grip brake
2.Remove the key from the ignition switch.
3.Press the Park release button while press
the release button at the shift lever to shift
from Park to Neutral.
4.Press on the brake pedal, restart the
engine
If you need to use the shift lock release, show
that maybe some problem exists at you
vehicle. Please get inspection from BYD

service shop.

Brake system
The tandem master cylinder brake system
has two separate sub-systems. If either sub
system should fail, the other will still work.
However, the pedal will be harder to press,
and your stopping distance will be increasing.

CAUTION

Do not drive your vehicle with only a
single brake system. Have your brakes
fixed immediately.



Brake booster
The brake booster uses engine vacuum to
power the brakes. If the engine should quit
while you are driving, you can bring the
vehicle to a stop with more pedal pressure.

CAUTION

Do not push the brake pedal if the
engine stalls. Each push on the pedal
uses up your reserved vacuum.

Even if the power assist is
completely lost, the brakes will still
work. But you will have to push the
pedal hard, much harder than normal.
And your braking distance will
increase.

Anti-lock brake system (with “ABS”
warning light)

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

F3/F3R OWNER’S MANUAL

- 139 -

The anti-lock brake system is designed to
help prevent lock-up of the wheels during
a sudden brake or brake on slippery road
surfaces. This assists in providing
directional stability and steering
performance of the vehicle under these
circumstances.

Effective ways to press the ABS brake pedal:
when the anti-lock brake system function is
working, you may feel the brake pedal
pulsating and hear a noise. In this condition,
to enable the anti-lock brake system to work,
just hold the brake pedal down more firmly.
Do not pump the brake in a panic stop. This
will result in reduced braking performance.
The anti-lock brake system becomes
operative after the vehicle has accelerated to
a speed in excess of approximately 5 km/h. It
stops operating when the vehicle decelerates
to a speed below approximately 5km/h.
In rainy days, it is easy to activate
anti-lock brake system when stepping on
brake pedal on slippery surface, such as the
cap of well, armor plate or the joint of bridges.

You may hear a click or motor sound in the
engine compartment for a few seconds when
the engine is started or just after the vehicle
begins to move. This means that the anti-lock
brake system is in the self-check mode, and
does not indicate a malfunction.
When the anti-lock brake system is
activated, the following conditions may
occur. They do not indicate a malfunction
of the system:

You may hear the anti-lock brake
system operating and feel the

brake pedal pulsating and the vibrations
of the vehicle body and steering wheel.
You may also hear the motor sound in
the engine compartment even after the

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

F3/F3R OWNER’S MANUAL

- 140 -

vehicle is stopped.

At the end of the anti-lock brake system
activation, the brake pedal may move a
little forward.


CAUTION

Do not overestimate the anti-lock brake
system: although the anti-lock brake
system assists in providing vehicle
control, it is still important to drive with all
due care and maintain a moderate speed
and safe distance from the vehicle in front
of you, because there are limits to the
vehicle stability and effectiveness of
steering wheel operation even with the
anti-lock brake system on.
If tire grip performance exceeds its
capability, or if hydroplaning occurs

during high speed driving in the rain, the
anti-lock brake system does not provide
vehicle control.

Anti-lock brake system is not designed to
shorten the stopping distance:
Compared with vehicles without an
anti-lock brake system, your vehicle may
require a longer stopping distance in the
following cases:

Driving on rough, gravel, or
snow-covered roads.

Driving with wheel chains installed.

Driving over the steps such as the
joints on the road.

Driving on bumpy or uneven roads.

Install all 4 tires of specified size at
appropriate pressure: the anti-lock
brake system detects

vehicle speeds using the speed
sensors for respective wheels’ turning
speeds. The use of tires rather than
specified may fail to detect the
accurate turning speed resulting in a
longer stopping distance.


Disk/drum integrated parking brake
Vehicle is equipped with drum parking
brake. This type of parking brake needs to
change brake shoe or brake drum
periodically and have them wear in by
your BYD AUTO service station.

Warning of brake pad

There is warning of brake pad. When the
brake pad is over-worn, there will be a
warning sound.

If you hear a scream or friction noise, please
contact with BYD AUTO service station to
replace the brake friction disc as soon as

possible.
Do not drive your vehicle for long time when
there is a warning sound.
Luggage storage precautions
When stowing cargo and luggage in the
vehicle, observe the following rules:

Put cargo and luggage in the trunk or
luggage compartment when possible.
Be sure all items are secured in place.

Be careful to keep the vehicle balanced.
Locating the weight as forward as
possible helps maintain balance.

For better fuel economy, do not carry
unneeded weight.

Suspension and chassis

CAUTION

Do not modify the suspension/chassis
with lift kits, spacers, springs, etc.
This can cause dangerous handling
characteristics, resulting in loss of
control.
