● To cool down the vehicle after being

parked under the hot sunlight, open the

windows and drive for several minutes

to let the hot air flow out, and then

raise the windows to cool using the air

conditioner in a short time.

● Confirm that the air suction grid in the

front of windshield is not blocked (such

as leaves or snow).

● When it is moist, do not cool the

windshield. Otherwise, condensation

may fog on the windshield due to the

temperature difference between the

inside and outside of the vehicle.

● You must keep it ventilated under the

front seat so as to make the air fully

recycled in the car.

● In cold weather, you must set the

rotating speed of blower to a high

speed for one minute so as to clear the

snow or moisture in the air inlet

channel. By doing so, you can reduce

fogging on the windows.

● When following other vehicles on a

dusty road or driving in windy and dusty

conditions, it is recommended to select

the internal air recirculation mode

temporarily. Thus the external air

suctions are closed to prevent external

air and dust entering the vehicle as well.

Cooling System

Refill motor coolant

If the coolant level is not higher than the

expansion tank Low limit scale (MIN), refill the

coolant or distilled water to the High limit

scale (MAX). Check the cooling system for

leakage. Please replace the specified coolant

after consulting the service personnels in the

BYD service station.

Always use the BYD original long-life

antifreeze coolant. It is unnecessary to add

any mixture. If it cannot be obtained then any

coolant not containing silicate from a

reputable brand could be used as a substitute.

Only use use recommended and qualified

coolants which are suitable for aluminum

motors. Otherwise, corrosion may occur and

will result the malfunction of the cooling

system or even failure if non-original coolant

is used for a long period. In this case, please

drain the cooling system in good time and

refill using BYD original antifreeze coolant. Do

not mix and use the coolants with different

brands and types.

If the expansion tank is drained completely,

check the radiator coolant level as well.

Tips

If the radiator cap is opened when the

motor hasn't cooled down thoroughly, the

coolant may spill out, resulting in serious

burn injuries.

Before opening the radiator cap, make sure

the motor, DC-DC, motor controller and

radiator have all cooled down.

a. Confirm that the motor, DC-DC, motor

controller and radiator have cooled down.

b. Turn the radiator cap counterclockwise

(without pressing down), until it cannot be

turned any more. The residual pressure in

the cooling system can be released

completely.

c. To remove the radiator cap, turn the cap

counterclockwise while pressing it.

d. The coolant level should reach the lower

edge of coolant filler neck. If the coolant

amount is still insufficient, please refill it

again.

Refill the coolant slowly and carefully to

prevent from spilling out. Since the spilled

coolant could damage the components in the

engine cabin. If it spills, clean it up

immediately and completely.

e. Install and tighten the radiator cap securely.

f.

Refill coolant into the expansion tank, until

the level reaches between the upper limit

scale (MAX) and Lower limit scale (MIN).

Then install the radiator cap.
