then it cannot start the engine,

and even lead to permanent

damage to the battery.

 Before leaving the car, make sure

the doors are closed and all

electric appliances are turned off.

Air Conditioning System

The air conditioning system is a closed

system, and any maintenance must be

performed by a BYD service station. To

keep it working effectively, you can

perform the following operations.

Regularly check the engine radiator

and A/C condenser. Remove leaves,

insects and dust attached to their

surfaces. These foreign substances

will block the airflow and reduce the

cooling effect. Clean them with a low

pressure spray gun or soft brush.

Tips

 The condenser plates and

radiator fins can bend easily.

Only use a low pressure spray

gun or soft brush to wash.

 Please run the air conditioner at

least once a week and ten

minutes each time during cold

seasons, when driving the

vehicle at a constant speed and

normal engine temperature, to

circulate the lubricant in the

coolant.

 If the cooling effect is not as

good as before, please contact

a BYD service station to

maintain it.

Driving Belt

Check the driving belt status, and

check every belt's edge for cracking

or abrasion.

Mitsubishi 4G69 engine's automatic

tension regulator can adjust the

tension of the driving belt. The needle

on the regulator should be in

appropriate range. Examine it

according to recommended driving

time and mileage in the periodical

maintenance schedule.

Tyre

To drive your vehicle safely, it should

be equipped with tyres of proper type

and size, and keep adequate tread

and correct tyre pressure.

Tyre Inflation

Keeping the tyres properly inflated

gives the best possible

manoeuvrability, ride comfort and

tread service life. Insufficient inflation

of tyres causes uneven wear, affects

manoeuvrability and fuel economy

and is more likely to cause the tyres to

BYD AUTO S6, S6A, S6K Owner's Instruction

Self-maintenance 7-12

fail due to overheating. If over-inflated,

the ride may be more harsh, and it

would be easier to cause damage

from road hazards, as well as cause

uneven wear.

For the recommended tyre pressures,

please refer to the placard on the

driver's door frame for correct

pressures when the tyres are cold.

Inspection

Every time you check the tyre pressure,

examine the tyres for damage, foreign

objects and abrasion as well.

a.

Replace the tyre if you find damage

and bulges on the tyre tread or sides.

b.

There are cuts, splits or cracks on

the tyre sides. Replace the tyre if its

fabric or cord is exposed.

c.

Replace if the tread is worn

excessively.

Tips

●

Maintain the correct tyre pressure

in case of the following conditions:

1）Low tyre pressure (insufficient air

filling)

2）Excessive wear

3）Abnormal wear

4）Hard steering

5）Air leakage due to overheating of

tyres

6）Deteriorated sealability at the

edge of tyre.

7）Deformation of wheel and/or

detachment of tyre and wheel

8）High Tyre Pressure (excessive air

filling)

9）Difficulty in operation

10）Excessive wear of centre of tyre

tread

The tyres have wear marks moulded

into the tread. When the tread wears

down, you will see a wide band

across the tread. This means that

there is less than 1.6 mm of tread left

on the tyre. As for this kind of tyre, it

may give very little adhesive force on

wet roads. Replace the tyre if you see

Tread wear marks

BYD AUTO S6, S6A, S6K Owner's Instruction

Self-maintenance 7-13

three or more tread wear marks.

Maintenance

In addition to properly inflating,

correct wheel alignment could also

decrease the tyre wear. If you find a

tyre is worn unevenly, contact a BYD

service station to check the wheel

alignment.

The tyre has been balanced at the

factory. If you feel a constant vibration

while driving, please contact a BYD

service station to check the tyres. If

any tyre ever has been repaired or

replaced, make sure to re-balance the

tyre.

Tyre Rotation

To extend the tyre service life and

make it wear more evenly, change the

position of tyres every 10,000 km. You

should move the tyres to the positions

shown above when performing each

rotation.

The figure above shows how to

change the vehicle's tyre position.

WARNING

●

Do not mix radial, bias-belted or

bias-ply tyres.

●

Do not use tyre sizes other than

those recommended by

manufacturers.

●

Do not use tyres on BYD S6 if

you do not know how they were

used previously.

Chains

Snow chains are only used for

emergencies or in special areas.

Install the snow chains on the front

wheels. Please pay special attention

when driving your vehicle with snow

Non-directional

wheels and tyres

Front

Directional wheels and tyres

Front

BYD AUTO S6, S6A, S6K Owner's Instruction

Self-maintenance 7-14

chains on slippery roads, such as

those covered with ice or snow. Since

some snow chains may damage the

tyres, wheels, suspensions and

vehicle body, choose chains with

small teeth in order to allow sufficient

gaps between tyre and other parts in

the wheel well. Look through and read

parts assembly graph and other

instructions of chain manufacturer

carefully. Before purchase and

installation, please consult a BYD

service station. After installation is

completed, drive on icy and snowy

roads below 30 km/h. To reduce the

abrasion of tyres and chains as far as

possible, please avoid driving with the

tyre installed chains on roads which

are not covered with ice and snow.

Tips

●

The driving speed should not be

higher than 30 km/h or the speed

specified by chain manufacturer.

●

Drive carefully with tyre chains

installed and avoid protrusion,

holes and sharp turns on the road,

which may jolt the car.

●

When tyre chain is installed,

avoid sharp turn or braking with

wheels locked, which may pose

adverse effect to car operability.

●

When tyre chains are installed,

slow the car down before turning to

prevent losing control of the car.

Lamps

The headlights have been aligned

before delivery. If the vehicle is

heavily loaded frequently, the

headlights may need to be aligned

again. Please go to a BYD service

station to complete this task.

Hold the bulb steel socket to replace.

Do not touch the glass portion of the

bulb with bare skin or hard objects.

Lamp Mist

After heavy rain or cleaning, the

combination lights, tail lights or turn

signals of exterior rear-view mirrors

may have mist. This is similar with the

phenomenon that one side of the

window condensates during rain, and

does not mean that your car has a

fault.

The lamps have relatively closed and

small space and the temperature is

high after lit (mask and mirror may be

deformed easily), and thus need heat

dissipation. In order to meet the

dissipation requirements after lit, the

lamps have vents in the lamp shell to

generate convection heat with the

surrounding environment. The greater

the temperature difference, the more

active the convection is. In the

BYD AUTO S6, S6A, S6K Owner's Instruction

Self-maintenance 7-15

convection process, the moisture in

the air will inevitably be brought inside

the lamp. Due to the solar radiation,

convection, and bulb heating, the

lamp is not a space of constant

temperature, so that moisture in the

air condenses into mist or water

droplets easily on the lamp surface

with low temperature. This heat

convection is a natural phenomenon.

Tips

 If the inside of the headlamps

and the inside of turn signals in

the exterior rear-view mirrors

have mist, the air humidity may

be high or the temperature

difference between the car and

its surroundings is great. In this

case, please turn on the

headlights or turn signals when

driving, and the mist will

disappear after a short period of

time.

 If water accumulates in the

lamps, please drive the car to a

BYD service station for repairs.

WARNING

When the headlight halogen bulbs

are on, they become very hot.

Grease, sweat or scratches on the

glass will result in bulb breakage

due to overheating.

Vehicle Storage

To park the vehicle for a long period

(over one month), prepare as follows.

These preparations may prevent the

vehicle from deteriorating and make it

easy to start it again. If possible, park

it indoors.

a.

Please refill fuel.

b.

Replace the engine oil and filter.

c.

Clean and dry the vehicle body

thoroughly.

d.

Clear the interior and make sure

that the carpet and floor mat is

completely dry.

e.

Release the parking handle. Apply

reverse gear (instruction transmission)

or parking gear (automatic

transmission).

f.

To park your vehicle for a long time,

support it with jack stands to clear it

from the ground.

g.

Open a window (if it is parked

indoors).

h.

Disconnect the battery cathode

cable.

i.

Raise the front wiper arm with a

towel or cloth to prevent it touching

the windscreen.

j.

To prevent sticking, spray silicone

ketene lubricant on the weather

sealing positions of all doors, and

apply wax to the connecting

BYD AUTO S6, S6A, S6K Owner's Instruction

Self-maintenance 7-16

positions of door sealing strips.

k.

Cover the body with a ventilated

cotton cover, as a plastic cloth will

damage the body paint because it

may accumulate moisture.

l.

If possible, start and run the engine

for a moment once per month.

If your vehicle is parked for more than

a year, please go to a BYD service

station to perform overall

maintenance.
