Tips

● Before driving, make sure that

parking brake is released fully
and the parking brake indicator
goes out.

● Do not leave the car when the

engine is running.

● Do not rest your feet on brake

pedal in driving, which may
cause dangerous overheating,
wear

and

higher

fuel

consumption.

● When on long downhill slope,

slow down the speed and shift
to low gear. Please note that the
brake will overheat and function
abnormally if you steps on the
brake pedal too many times.

● Take special care when

speeding up, shift to
higher/lower gear, or braking on
slippery road. Hard acceleration
or engine braking may result in
skidding or spinning of the car.

● Do not continue driving when

the brake is wet. Wet brake
requires longer braking
distance and may cause
deviation of the direction of the
car. Also, in this case parking
brake can not stop the car
firmly.

Do not stretch any part of your

body out of the window in
driving, which may cause
severe accidents and risk
severe personal injury. Take
special care when there are kids
on the car.

Note

When driving on damp road,
avoid deep water as when a large
amount of water enters engine
compartment, the engine and/or
electrical parts may be damaged.

Driving Tips in Winter

Make sure coolant is suitable for use
in winter.

Only use cooling fluid authorized by
BYD service station. Choose and add
suitable type of cooling fluid into cooling
system

according

to

environment

temperature.
Improper cooling fluid may damage
engine cooling system.

Note

Do not over use water, which may
damage engine cooling system in
winter.

Check Battery and Cable Status

Cold weather may reduce battery
performance, and you shall keep the
battery high enough for starting in the
winter. Visual check of the battery is
described in section 7-3. BYD service
station can check charging status of the
battery for you.

BYD G3 AUTO Owner’s Instruction

95

Make sure viscosity of the engine oil
is suitable for driving in winter.

Please refer to section 7-2 for
information on recommended viscosity
of engine oil. If a large volume of engine
oil for summer use is left in the engine in
winter, it may cause difficulty for engine
starting. If you are not sure about
choosing engine oil, please contact BYD
service station for help.

Avoid Door Lock Freezing
Spray some deicing agent or glycerin in
door lock hole to prevent the lock from
freezing.

Use Cleanser with Antifreeze
It is available in BYD service stations
and all auto part stores. Mixing ratio of
water and antifreeze shall follow
manufacturer's instruction.

Note

Don’t use engine antifreeze or
other substitutes as cleanser, as
they will damage the vehicle
paint.

Do not apply parking brake if it may
be frozen up.
In parking, shift to gear shift lever to N
gear and place obstacles around rear
wheels to retain the car. Do not apply
parking brake as it may be frozen up by
water or snow, resulting in difficulty to
release the parking brake.

Prevent snow from staying under
mudguard.
Snow or ice under mudguard may make
steering difficult. When driving in winter,
you shall stop the check regularly to
check whether there is ice or snow
under mudguard.

You are recommended to keep
certain emergency tools on the car
according to your region.
Examples of such articles are tire chains,
window wiper, a bag of sand or salt,
flasher signaling device, shovel and
connection cables.

Tow Trailer

BYD G3 is designed for transportation of
passengers. Towing a trailer may pose
bad effect to operation, performance,
braking, endurance, fuel economy of the
car. Safety and comfort in driving
depends on proper use of devices and
the driver’s habitual care in driving.
For the sake of safety of yourself and
others, do not over load the car or tow a
trailer.Damage or failure cause by
towing a trailer for business purpose is
not covered by BYD warranty.

Weight Limit
Before towing a trailer, make sure it is

within the car’s capacity. You can
contact the local BYD service station to
check the trailer's capacity.
Towing capacity is measured on level
road. In region with high altitude, please
take note that the engine power and its
towing capacity will reduce.

BYD G3 AUTO Owner’s Instruction

96

Tips

Towing trailer shall not exceed
the maximum rated load of the
two-hook, or it may cause an
accident and severe personal
injury.
As towing a trailer may require
longer braking distance, you shall
keep a larger interval with other
vehicles. For each 10 km/h, the
interval between you car and the
vehicle in front of you shall be no
less than the total length of your
car and the trailer. Avoid hard
braking to prevent the car from
skidding, which may get the car
out of control.

Tire

● Make sure the tire pressure is proper.

Refer to description in section 7-2.

● Taking the total weight of a trailer into

consideration, keep its tires with
proper pressure as specified by its
manufacturer.

Running-in Procedure
● For a new auto or after it undergoes

replacement of driving system parts
(engine,

transmission,

differential

mechanism, wheel bearing, driving
shaft, etc.), do not tow any trailer in the
first 2000 km travel.

Maintenance
● When towing a trailer, the increased

load

requires

more

frequent

maintenance of the car.

How to Save Fuel and Extend Auto
Service Life

In simple and easy way you can save
fuel. Fuel-saving is also helpful to
extend service life of the car. Here are
some

tips

on

saving

fuel

and

maintenance expense:

● Maintain proper pressure in tires.

Insufficient tire pressure may cause
excessive tire wear and waste fuel.
Refer to description in section 7-2.

● Do not leave unnecessary articles on

the car. Weight of unwanted articles
will

increase

engine

load

and

consume more fuel.

● Avoid engine long time running idle for

warming up. Once the engine running
is stable, you shall speed up the car
stably. Take note that in cold weather
the engine warming up may take
longer time.

● Acceleration shall be slow and stable.

Avoid hard acceleration. Try to shift to
high speed gear as soon as possible.

BYD G3 AUTO Owner’s Instruction

97

● Avoid engine running idle for a long

time. If the car must be stopped for
long period, you had better shut down
the engine.

● Avoid engine lug-down or overspeed.

Select appropriate gear according to
road surface conditions.

●

Avoid

unnecessary

alternative

acceleration and deceleration, which
will waste of fuel.

● Avoid unnecessary stopping or

braking. In driving, if you keep a
steady vehicle speed while taking
traffic

signaling

lights

into

consideration, you can stop your car
for fewer times; and if possible, take a
road without traffic lights. Keep proper
interval with the vehicle in front of you
to avoid hard braking, which is also
helpful to reduce brake wear.

● Avoid driving in traffic peak hours or

traffic jam region.

● Do not rest your feet on clutch pedal

or brake pedal. It will cause excessive
wear, overheating and higher fuel
consumption.

● Keep proper speed on expressway.

The higher speed, the larger fuel
consumption. Slower speed can save
fuel.

● Keep Front Wheels in Proper

Alignment Do not impact on curbstone,
and slow down the speed on rugged
road. Bad alignment of front wheels
may cause excessive wear of tires,
and also increase engine load and
fuel consumption.

● Keep the chassis clean and free of

mud and similar materials. It helps to
reduce vehicle weight and prevent
corrosion.

● Adjust and Keep Vehicle at Best
Performance Dirty air filter, spark plug,
engine oil and lubricant, improper
throttle clearance, badly adjusted brake,
etc. may have bad effect on engine
performance

and

increase

fuel

consumption. To extend service life of
all parts and reduce operating expense,
regular maintenance is required. When
driving under poor conditions, such as
bad weather, maintenance to the car
shall be more frequent (Refer to Chapter
6).

Tips

It is prohibited to shut down the
engine when running down a
slope. The power steering and
vacuum booster will be disabled
when the engine is off. Similarly,
emission

pollutant

control

devices only function when the
engine is running.

If Engine Stalls in Driving

If Engine Stalls in Driving…
1. Please slow down the car slowly,

keep moving in a straight way and
run off the road to a safe place.

2. Turn on the emergency flashlight.
3. Try again to start the engine.
If the engine can not start up, please see
"If the Car Cannot Start Up".

Tips

When the engine is not running,
boosters of brake and steering
device do not work, which makes
steering

and

braking

more

difficult than usual.
● If the engine stalls in driving, do
not open the driver's door before
the

car

stops

completely.

Steering wheel will be locked
once the driver’s door is opened,
which may cause the car out of
control.

If the Car Is Overheated

If the engine coolant thermometer
indicates overheated, or there is power
loss, loud knocking, or noisy bang, that
means the engine may be overheated.
Please handle it as per the procedures
below…

1 Drive the car off road, stop it and turn

on the emergency flashlight. Set the
transmission to N gear, and apply the
parking

brake.

Shut

down

air

conditioning if it is running.

2. If there is coolant or steam spouting

out of the radiator or expansion tank,
please shut down the engine. Open
engine hood after steam fades away. If
no coolant or steam is spouting, just
keep the engine running and make
sure the cooling fan is working; if not,
please turn off the ignition switch.

Tips

To avoid personal injury, please
keep the engine hood closed until
there is no steam coming out. The
spouting of steam or coolant
means high pressure.

BYD G3 AUTO Owner’s Instruction

3. Check whether there is obvious

coolant leakage under the radiator,
hose, and the car. Water drops
produced by AC system in use are
normal.

Tips

When engine is running, please
keep your hands and clothes
away from the working fan &
driving belt of the engine.

4. If there is coolant leakage, please

shut down the engine at once and
contact BYD service station for help.

5. In case of no obvious leakage, please

check the coolant reservoir. If it is dry,
please add coolant to the reservoir
until the level is between two scale
marks while the engine is running.

Tips

Under high temperature, it is not
allowed to remove the radiator
cap since the spouting
high-temperature steam and
liquid under pressure may cause
serious personal injury.

6. When the coolant temperature falls

down to normal, check the coolant
level in the tank again and add
additional coolant if necessary. Large
drop of coolant level means leakage in
the system; please contact BYD
service

station

for

immediate

examination.
