take up the hand brake first.
When the car is parked on the
ramp, the car may move
downwards slightly when the
brake pedal is released. Before
shifting the transmission to park
position, take up the hand brake
to avoid applying pressure on
the parking mechanism in the
transmission when the car
moves, so that the lever can shift
from the park position easily
when you want to drive the car.

Ramp start
To protect the DCT transmission,
please use the hand brake to assist
the start on steep ramp.
Special environment
In case of downhill, bend, or mountain
road, we recommend using the
manual mode, and shift to lower
position in order to take full advantage
of engine braking.

Friendly Tips



If the car is frequently started or

drives at "low speed", or start and
stop with the traffic for a long time,
it may result in overheating of the
DCT transmission clutch.

In the first 1,000km, pay special
attention to the driving mode to
ensure the reliable performance of the
car. Note the following in this period:
1. Avoid full throttle in starting and

driving.

2. Avoid emergency braking in the

first 300km.

3. Do not replace the engine oil

before reaching the time or
mileage recommended in the
regular maintenance table.

Also follow above notice after
overhaul, or replacing the engine or
friction plate.
Fuel
1. 483QB engine and 476ZQA

engine can use octane rating 93
or higher grade unleaded
gasoline.

2. Using leaded gasoline will

damage the emission control
device and engine of the car, and
also will aggravate air pollution.

3. Using low grade or low-quality
gasoline will reduce engine life.
4. For 476ZQA turbocharged engine,

it is recommended that use higher

Friendly Tips

When refueling, note the
following points:



Gasoline is easily flammable.
When refueling, shut down the
engine, stay away from heat
source, sparks and open
flames, and do not smoke.
Open flame is easy to cause a
fire.



When opening the fuel tank
cap, do not immediately
remove the cap. In hot weather,
if the fuel tank cap is removed
suddenly, the fuel under
pressure will eject from the
filler and cause personal injury.



It is recommended that refuel
outdoor and immediately wipe
away spilled fuel.



Do not overfill the fuel, which
helps reduce fuel consumption
and improve the life of
activated carbon canister;



Please go to a regular gas
station for refueling;
counterfeit and shoddy fuel will
make your engine jitter and

have weak speed up and other
faults.

driving and cause an accident.

Gasoline detergent
1. Gasoline detergent can effectively

remove carbon deposits, sludge
and other sediments of the engine
fuel system.

2. For turbocharged and direct

injection engines, the gasoline
detergent must be applied
according to requirements
properly on a regular basis and in
sufficient quantities. For naturally
aspirated engines, the gasoline
detergent can also be applied
reasonably based on the
maintenance cycle and condition
of the engine.

3. BYD authorized service station

provides proven

“BYD dedicated

gasoline detergent

”.

4. Not all gasoline detergents are

valid. The use of inappropriate
gasoline detergent may cause
engine damage. BYD approved
gasoline detergent is
recommended.

Checking engine oil
It is normal that the engine consumes
engine oil. The actual engine oil
consumption depends on your driving
and running conditions of the car.
Therefore, the oil level must be
checked regularly. It is best to check
the liquid level every time when
refueling or before long-distance
traveling, and refill if necessary.
1. Take out the oil level gauge.
The upper and lower limits of the
engine oil level gauge are two convex
lines, which are labeled as "F" and "L";
the oil level should be located
between the upper and lower limits.

2. Wipe the oil level gauge with a

clean cloth or paper towel.

3. Insert the oil level gauge back to

the sleeve.

4. Take out the oil level gauge again,

and check the oil level. The oil
level must be between the upper
and lower limits.

Driving Tips 2-5

Checking engine coolant

View coolant level in the radiator tank.
Confirm whether it is between scale
lines of the upper limit (MAX) and the
lower limit (MIN).
Fuel-saving tips (driving habits)
Smooth driving helps save fuel.
Acceleration, sharp turns and
emergency brakes will consume more
fuel.
Try to keep driving in top position to
ensure smoother engine operation
and acceleration.
According to traffic conditions, try to
keep at constant speed. Each

deceleration or acceleration of the car
will increase fuel consumption. In the
appropriate driving conditions, using
constant speed cruise control
(optional) will save more fuel. Cold
state engine consumes more oil than
thermal state, but there is no need for
warm-up and let it idle for a long
period of time. No matter how cold
outdoor, the car can be driven away in
one minute after the engine is started.
In this way, the engine will heat up
faster, thus saving fuel. Try to arrange
shorter mileages together, in order to
reduce the times of "cold state start".
Turning on the air conditioner will
increase the engine load, which
consumes more fuel. Turning off the
air conditioner can reduce fuel
consumption. When the atmospheric
temperature is suitable, outdoor
circulation pattern should be used.

Carrying luggage
The car is equipped with a number of

convenient storage locations, which
can be used to carry the luggage
safely.
The right glove box, door paper bags
and seat back paper bags are
designed for storing small pieces and
lightweight items, while the luggage
compartment is used for storage of
larger and heavier items.
In addition, the luggage compartment
channel opening allows you to carry
long items in the car.
However, the handling, stability and
normal running of the car may be
affected and the safety is reduced if
carrying too much luggage or loading
improperly.
Load limit
When loading luggage, the total mass
of the car body, all passengers and
luggage must not exceed the
maximum allowable mass.

Warning



Overloading and improper

loading will affect vehicle
handling and stability, and may
lead to the crash and
casualties.



Please follow the load limit and
other load criteria in this
manual.

Carrying objects in passenger area
1. Properly put or fix all objects that

may be thrown to the car and hurt
the passenger in case of car crash;

2. Do not keep any object on the rear

window board. Otherwise, these
objects will restrict your sight, and
will be thrown everywhere in the
car crash;

3. To ensure that the objects placed

on the rear floor of the front seat
won’t roll under the seat, thus
affecting the regulation of driver
control pedal or seat. Do not push
the goods beyond the front
seatbacks;

4. While driving, ensure that the

glove box has been closed. If the

glove box lid is open, the knees of
the passenger may be hurt in a
crash or emergency stop.

Carrying luggage in the luggage
compartment
1. Put the luggage evenly on the

floor in the luggage compartment,
and put the heaviest luggage on
the bottom and as front as
possible;

2. Fix the objects with a rope or

chain to prevent it from moving
when you are driving. Do not
make the stacked objects higher
than the seat backs of the front
seats;

3. If the bulky objects impede you

close the luggage box cover, the
discharged exhaust gas will enter
the passenger area.

shift to "1" position or "R"
position; set the shift lever in
neutral position, release, step on
the clutch pedal and then shift;



While driving, except shifting

gear, do not put hand on the shift
lever at other time, or else it will
accelerate the wear of

transmission;



When shifting from high position to

low position, do not downshift two or
more gear positions, or shift to low
position when the engine is at high
speed (5000Km/min), or else it will
damage the engine.

Driving tips under different
conditions



When driving against the wind,
you should drive slowly so that
the vehicle can be controlled
easily.



Avoid driving on high and sharp
objects or other road obstacles;
otherwise, severe tire damages,
e.g. explosion, may be caused.



Reduce the speed when driving

Frequent brake
manipulation will lead to
over-heat and, possibly,
performance faults.



Care should be taken in
accelerating, high gear
shift, low gear shift or

braking on slippery roads.
Sudden acceleration or
engine brake will lead to
vehicle sliding or turning.



Do not drive if the brakes
are moistened. When the
brakes are moistened,
longer brake distances are
needed, and, the vehicle
may be hauled to one side
when the brakes are used.
Similarly, the parking
brake cannot park the
vehicle firm either.



While driving, do not reach
the head or hands out of
the window, to avoid
accidents and hazard,
especially when children
are in the car.

Driving tips in winter
Make sure the coolant has proper
anti-freezing protection effect.
Only coolants specified by BYD
authorized service stations can be

applied. You should select proper
coolant according to the environment
temperature and add it into the cooling
system.
Application of unsuitable coolants will
damage the engine cooling system.

Warning



Do not use water in the

Do not use the engine
anti-freezing agent or other
substitutes as the cleaning
liquid, since it may damage the
vehicle paint.

Do not use the parking brake if it
may be frozen.
For parking, set the gear lever in
the neutral gear and block up the

rear wheels. Avoid using the parking
brake; otherwise, its periphery may be
frozen by accumulated water or snow,
causing it difficult to release.
Make sure there is no accumulated
snow or ice under the dashboard.
Accumulated snow or ice under the
dashboard may lead to turning difficulty.
In freezing winter, you should stop
often to see whether there is any
accumulated ice or snow under the
dashboard.

It is suggested you carry some
necessary tools for emergent use
according to the road conditions.
It’s best you have a tire chain, a
window scraper, a bag of sand or salt,
a signal flashing device, a small shovel,
connecting cables, etc. in the vehicle.
Trailer towing
BYD F7 is designed mainly for
transporting passengers. Towing
trailers will exert adverse influence on
operation, performance, brake,
durability and economical driving (fuel

consumption, etc.) Safety and comfort
of driving are totally dependent on
correct use of the instruments and a
good driving habit. For your own and
others’ safety, do not overload the
vehicle or use it to haul trailers. BYD
won’t take responsibilities for damage
or faults caused by trailing with
commercial purposes.
Weight limit
Before towing a trailer, the towing
capacity of the trailer should be
confirmed. You can contact a local
BYD authorized service center and
make sure that the towing capacity of
the trailer is within the regulated range.
The towing capacity is determined on a
flat road surface. It should be
remembered that in mountainous
regions, the engine power and its
towing capacity will be reduced.

Friendly Tips

The hauled trailer weight
should not exceed the
