Precautions on Self-maintenance

In case of self maintenance, you

must follow the correct procedures

in this section.

This Chapter only explains

maintenance operations which can

easily be carried out by yourself.

However, some items must still be

performed at a BYD service station.

During operation, you must pay special

attention to avoiding accidental injuries.

You are required to follow the special

preventive measures below.

Tips

●

When the engine is running, you

must keep your body, clothes and

tools away from the running fans

and drive belt of the engine, and

remove items such as rings,

watches and neckties.

●

Immediately after driving, some

components in the engine

compartment will be very hot, so

observe caution and do not touch

them.

●

If the engine is hot, do not remove

the radiator cap to prevent burning

yourself.

●

Do not leave inflammable, such

as paper or rags, in the engine

compartment.

●

Be sure that the power is off if you

work near the electric cooling fan or

radiator grille. With the power on, the

electric cooling fan will automatically

start to run if the engine coolant

temperature is high or the air

conditioning is turned on.

●

Do not smoke for fear of causing

a fire around the fuel tank or the

battery.

●

Be sure to handle the battery with

special care, as it contains corrosive

sulphuric acid.

●

Do not go under your vehicle with

only the body jack supporting it.

Always use automotive jack stands or

other solid supports if you have to

work under your vehicle.

●

Use goggles whenever you work

on or under your vehicle to prevent

injury.

●

Since the brake fluid is harmful to

eyes and paint surface, be careful

when refilling. If the brake fluid

comes into contact with your skin,

rinse with soap water. If the brake

fluid comes into contact with your

eyes, wash your eyes at once, and

seek medical advice immediately.

●

Window cleaner, steering fluid

and brake fluid are flammable, keep

them away from sparks and naked

BYD AUTO S6, S6A, S6K Owner's Manual

Self-maintenance 7-3

flames.

●

The battery and ignition coils bear

high current or high voltage. Protect

their terminals to avoid shorting.

●

If the coolant or brake fluid

overflows, rinse with water to avoid

damaging the components or paint

finish.

●

Do not drop anything into the

spark plug hole.

●

You can only use the specified

spark plug. Using another spark plug

may damage the engine or generate

electromagnetic interference.

●

Do not refill too much power

steering fluid, or it may overflow

when starting the vehicle.

●

Do not drive with the air filter

removed, otherwise it may cause

excessive engine wear due to dust

being drawn into the cylinders and

causing backfire in the engine

compartment.

●

Note: do not scratch the glass by

the wiper bracket.

Open Engine Bonnet

WARNING

●

Before driving, be sure that the

bonnet is closed and securely

locked. Otherwise, the bonnet may

open unexpectedly while driving

and an accident may occur.

Self-maintenance 7-4

Engine oil

Engine oil is a kind of Consumable,

which is very important to ensure the

engine runs normally. Therefore,

check the engine oil level regularly.

The consumption of engine oil is

determined by driving, weather and

road conditions. For a new engine,

the oil consumption may be more.

Make sure to park the car on level

ground, switch off the engine and wait

for 3 minutes, then check the engine

oil level.

If the oil level is near or lower than the

low oil scale line, you must go to a

BYD service station to add the

appropriate amount of engine oil.

Recommended engine oil

Engine oil is a major contributor to

your engine's performance and

service life. Therefore, always use

high-quality and detergent engine oil.

For your vehicle, it is recommended to

use the same grade engine oil or

above.

API grade: SG or above

SAE:Choose the appropriate oil type

for local climate”

WARNING

●

Do not splash engine oil on parts

of the car.

●

Check the oil level on the oil

dipstick once again after engine oil

refilling. Avoid overfilling, or the

engine could be damaged.

●

Engine oil, engine components

and exhaust system may be very

hot and lead to burns. Be careful

and wear protective clothes when

operating in the engine

compartment.

●

Prolonged and repeated contact

with used engine oil may cause skin

irritation. If your skin comes into

contact with this kind of engine oil,

wash it with soap and clean water.

Cooling System

MAX

MIN

BYD AUTO S6, S6A, S6K Owner's Manual

Self-maintenance 7-5

If the coolant level in the coolant

reservoir is at or below the (MIN)

scale, fill coolant to the (MAX) scale.

Note that coolant of different brands

and types cannot be mixed.

Inspect the cooling system for leaks. If

the reservoir is completely empty, you

should also check the coolant level in

the radiator.

Never add any rust inhibitor or other

additives to the cooling system, since

the additives may not be compatible

with the coolant or engine

components.

WARNING

To avoid burning, do not remove

the radiator cap when the engine is

hot.

Windscreen Washer

Check the level in the windscreen

washer reservoir at least once a

month during normal using. In poor

weather conditions, if you use the

washer frequently, check the level in

the windscreen washer reservoir

when adding fuel.

The windscreen washer reservoir is

located in the engine compartment

behind the right headlight.

Check the reservoir's level by

removing the cap and looking at the

level gauge attached to the cap.

Fill the reservoir with a good-quality

windscreen washer fluid. This can

increase the cleaning capability, and

prevent freezing in cold weather.

When you refill the reservoir, clean

the edges of the windscreen wiper

blades with windscreen washer fluid

on a clean cloth. This will help to keep

the blade edges in good condition.

WARNING

●

Do not fill the windscreen washer

reservoir with engine antifreeze or a

vinegar/water solution. Antifreeze can

damage the vehicle's paint, while a

vinegar/water solution can damage

BYD AUTO S6, S6A, S6K Owner's Manual

Self-maintenance 7-6

the windscreen washer motor.

●

It is recommended to only use the

windscreen washer fluid which is

available from BYD service stations.

Wiper Blade

The blade strips made of synthetic

rubber, are wearing parts. The using

environment of the car and the habits

might cause damage to the blade, so

in order to ensure the life of the blade

and the driving safety, please note the

following.

1. Do not scrape the ice from the

windshield surface with the blade;

use a special ice scraper instead;

2. Do not scrape dirty, oily or waxed

windshield surface;

3. Keep the windshield surface clean,

and do not scrape the dust, sand,

insects and foreign matter on the

windshield surface;

4. During washing and body paint

maintenance, it is not necessary to

wax the windshield. The wax layer

will reflect light in poor lighting,

which will affect the sight and traffic

safety. Rinse with purified water

after washing the blade, and use

specialized glass-wax cleaning

agent to remove the wax layer on

the windshield;

5. Do not rinse the blade with water

gun directly when washing the car

to prevent damage to the blade due

to high water pressure.

Lift the wiper arm before cleaning the

windshield; the specific methods of

operation are as follows:

1. Turn off the car power;

2. Grasp the upper end of the wiper

arm with the thumb and other

fingers, and lift the wiper arm and

blade assembly carefully.

Tips

 Regularly clean the windshield and

wiper blade (once every one or two

weeks).

 It is also recommended to wipe

periodically even if it does not rain

(once every one or two days).

 The windshield must remain fully

wet when scraping the windshield

with the blade (if it doesn

’t rain,

spray the windshield with washing

liquid first).

 Use special windshield cleaner to

clean the windshield.

 If soil or insect's body adheres to

the windshield, wipe with a rag

timely.

 If the windshield has pits knocked

by gravel, service or replace timely.

 Replace the wiper blade regularly

(every six months).

BYD AUTO S6, S6A, S6K Owner's Manual

Self-maintenance 7-7

Transmission Fluid

Checking, changing and refilling

transmission fluid requires

professional skill and knowledge, so

please contact a BYD service station

to perform these operations.

Brake Fluid and Clutch Fluid

Check the fluid level in the fluid

reservoir monthly. The two types of

fluid are in the same reservoir.

Replace the brake fluid according to

recommended driving time and mileage

in the periodical maintenance schedule.

Make sure to use BYD original brake

fluid DOT4. The other types of brake

fluid are not compatible with your

vehicle's braking system. The brake

system and clutch system should use

the same type of brake fluid.

Brake System

The fluid level should be between the

lower (MIN) and upper (MAX) marks

on the side of fluid reservoir. If the

level is at or below the (MIN) mark,

check the braking system. Check the

braking system for leakage and brake

discs for abrasion.

Power Steering Fluid

Check the fluid level in the power

steering fluid reservoir monthly; this

task should be performed after the

engine has cooled down. Look over

the side of reservoir, the fluid level

should be between the upper level

and lower level. If it is below the lower

level, refill the power steering fluid so

the fluid level is up to the upper level.

Drop in power steering fluid level

means that the power steering system

may be leaking. Check the fluid level

frequently and check this system as

soon as possible.

Tips

 Make sure to only use BYD

specified power steering fluid.

Use of other types of power

steering fluid will damage the

power steering system.

 Refill the fluid slowly and

carefully and do overflow. Clean

up any spilled fluid immediately

as it may damage the

Upper
mark

BYD AUTO S6, S6A, S6K Owner's Manual

Self-maintenance 7-8

components in the engine

compartment.

 Please contact BYD service

station if you have any doubt

about checking fluid level or filling

fluid in gearbox.

 Do not turn the steering wheel to

the left or right end for a long

period. Otherwise, it may

damage the power steering

pump.

Three-way Catalytic Converter

The three-way catalytic converter

contains precious metals which are

catalysts and accelerate the chemical

reaction to purify exhaust gases,

however, the metal hasn't been

affected. Three-way catalytic

converter has a positive effect on the

HC, CO and NOx. To replace it, BYD

original parts must be used.

To cause the chemical reaction, the

three-way catalytic converter must

work at high temperatures, it may

combust surrounding inflammables.

Therefore, park your vehicle at a

location far away from combustible

objects such as dry grass and leaves.

In the event of failure, the three-way

catalytic converter will cause air

pollution, and engine efficiency will be

reduced. Please protect it according

to the following rules.

a.

Keep using unleaded petrol. Even if

it contains a little lead, it will also

pollute the catalytic metal and

cause failure.

b.

Keep the engine running normally.

c.

If your vehicle misfires, backfires,

stalls or develops another

abnormal symptom, check and

repair it immediately.

WARNING

When the engine is running, stay

away and keep inflammable

material away from the exhaust

pipe. The hot gas from the exhaust

pipe may cause injury or fire.

Air Filter Element

Clean and replace the air filter

element according to recommended

driving time and mileage in the

periodical maintenance schedule.

The air filter element is installed in the

air filter case on the driver side of

engine compartment.

BYD AUTO S6, S6A, S6K Owner's Manual

Self-maintenance 7-9

Clean

Intake compression air into air filter

element through the opposite

direction. If you can't obtain the

compression air, please let a BYD

service station deal with it.

Fuel Filter

Replace the fuel filter according to

recommended driving time and

mileage in the periodical maintenance

schedule.

If you find the fuel is polluted, the fuel

filter will clog quickly, so it is

recommended to replace the fuel filter

every 10,000 km or every 6 months.

Please go to a BYD service station to

replace the fuel filter. If the fuel

pipeline is not attached properly, fuel

may spill out and lead to danger due

to pipeline internal pressure.

If you have ever used one or more

barrels of impure fuel, you should

replace the fuel filter earlier. If you find

the filter is clogged by dirt, you should

invite a BYD service station to check

or replace the fuel filter.

Engine Bonnet Lock

Use mild detergent to clean the

engine bonnet lock, then wipe on

multipurpose lubricating oil. You

should contact a BYD service station

to handle it.

WARNING

Make sure that the engine bonnet

lock is locked before driving.

Battery

Check the battery once per month.

You should check the colour of the

viewport window as well as for any

terminal corrosion.

Check the extent of battery terminal

corrosion (white or yellow powder). To

remove it, you should apply sodium

bicarbonate to the surface of the

terminals, the terminal will produce air

bubbles and gradually turn brown.

When the bubbles disappear, clean

using clean water, and dry with cloth

Pivot
