Get Convenience features -> System maintenance Guide for Hyundai Bayon SUV Second Generation (2021-2024)

Convenience features

• Use the air conditioning system every

month only for a few minutes to

ensure maximum system perfor-

mance.

• When using the air conditioning sys-

tem, you may notice clear water drip-

ping (or even puddling) on the ground

under the passenger side of the vehi-

cle. This is a normal system opera-

tion characteristic.

Information

• When using the air conditioning sys-

tem, monitor the temperature gauge

closely whilst driving up hills or in

heavy traffic when outside tempera-

tures are high. Air conditioning sys-

tem operation may cause engine

overheating. Continue to use the

blower fan but turn the air condi-

tioning system off if the temperature

gauge indicates engine overheating.

• When opening the windows in humid

weather, air conditioning may create

water droplets inside the vehicle.

Since excessive water droplets may

cause damage to electrical equip-

ment, air conditioning should only

be used with the windows closed.

• If you operate the air conditioner

excessively, the difference bet-ween

the temperature of the outside air and

that of the windscreen could cause

the outer surface of the windscreen to

fog up, causing loss of visibility. In

this case, set the mode selection but-

ton to the

position and set the

fan speed control knob to the lowest

speed setting.

Air conditioning system operation

tips

• If the vehicle has been parked in

direct sunlight during hot weather,

open the windows for a short time to

let the hot air inside the vehicle

escape.

System maintenance

Climate control air filter

• After sufficient cooling has been

achieved, switch back from recircula-

tion mode to fresh mode.

• To help reduce moisture inside of the

windows on rainy or humid days,

decrease the humidity inside the

vehicle by operating the air condition-

ing system with the windows and

sunroof closed.

• During air conditioning system opera-

tion, you may occasionally notice a

slight change in engine speed as the

air conditioning compressor cycles.

This is a normal system operation

characteristic.

OIK047401L

[A] : Outside air, [B] : Recirculated air

[C] : Climate control air filter, [D] : Blower

[E] : Evaporator core, [F] : Heater core

This filter is installed behind the glove

box. It filters the dust or other pollutants

that enter the vehicle through the heat-

ing and air conditioning system.

We recommend that the climate control

air filter be replaced by a HYUNDAI

authorised repairer according to the

maintenance schedule. If the vehicle is

being driven in severe conditions such

as dusty or rough roads, more frequent

climate control filter inspections and

changes are required.

NOTICE

It is important that the correct type

and amount of oil and refrigerant is

used. Otherwise, damage to the

compressor and abnormal system

operation may occur. To prevent

damage, the air conditioning system

in your vehicle should only be ser-

viced by trained and certified techni-

cians.

If the air flow rate suddenly decreases,

we recommend the system be checked

at a HYUNDAI authorised repairer.

WARNING

Information

Vehicles equipped with R-134a

• Replace the filter according to the

Maintenance Schedule.

If the car is being driven in severe

conditions such as dusty, rough

roads, more frequent climate control

air filter inspections and changes are

required.

• When the air flow rate suddenly

decreases, we recommend that the

system be checked by a HYUNDAI

authorised repairer.

Since the refrigerant is

operated at very high

pressure, the air condi-

tioning system should

only be serviced by

trained and certified technicians.

All refrigerants should be reclaimed

with proper equipment.

Venting refrigerants directly to the

atmosphere is harmful to individuals

and environment. Failure to heed

these warnings can lead to serious

injuries.

Checking the amount of air con-

ditioner refrigerant and com-

pressor lubricant

When the amount of refrigerant is low,

the performance of the air conditioning

is reduced. Overfilling also has a bad

influence on the air conditioning sys-

tem.

Therefore, if abnormal operation is

found, we recommend that the system

be inspected by a HYUNDAI authorised

repairer.
