Information 

• When using the air conditioning sys-

tem, monitor the temperature gauge
closely while 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 elec-
trical equipment, air conditioning
should only be used with the win-
dows closed.

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.

• Use air conditioning to reduce

humidity and moisture inside the
vehicle on rainy or humid days.

• During air conditioning system

operation, you may occasionally
notice a slight change in engine
speed as the air conditioning com-
pressor cycles. This is a normal
system operation characteristic.

• Use the air conditioning system

every month only for a few minutes
to ensure maximum system per-
formance.

• When using the air conditioning

system, you may notice clear water
dripping (or even puddling) on the
ground under the passenger side
of the vehicle. This is a normal sys-
tem operation characteristic.

• Operating the air conditioning sys-

tem in the recirculated air position
provides maximum cooling, how-
ever, continual operation in this
mode may cause the air inside the
vehicle to become stale.

• During cooling operation, you may

occasionally notice a misty air flow
because of rapid cooling and
humid air intake. This is a normal
system operation characteristic.

System maintenance

Climate control air filter 

The climate control air filter installed
behind the glove box filters the dust
or other pollutants that come into the
vehicle from the outside through the
heating and air conditioning system.
If dust or other pollutants accumulate
in the filter over a period of time, the
air flow from the air vents may
decrease, resulting in moisture accu-
mulation on the inside of the wind-
shield even when the outside (fresh)
air position is selected. If this hap-
pens, we recommend that the cli-
mate control air filter be replaced by
an authorized retailer of Genesis
Branded products.

Information 

• 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 an authorized
retailer of Genesis Branded products.

Air Conditioning refrigerant
label

The actual Air Conditioning refriger-
ant label in the vehicle may differ
from the illustration.

Each symbols and specification on
air conditioning refrigerant label
means as below:

1. Classification of refrigerant
2. Amount of refrigerant
3. Classification of Compressor lubri-

cant

You can find out which air condition-
ing refrigerant is applied to your vehi-
cle on the label located inside of the
hood.

Checking the amount of air con-
ditioner refrigerant and com-
pressor lubricant

When the amount of refrigerant is
low, the performance of the air condi-
tioning is reduced. Overfilling also
has a bad influence on the air condi-
tioning system.
Therefore, if abnormal operation is
found, we recommend that the sys-
tem be inspected by an authorized
retailer of Genesis Branded products.

03

Vehicles equipped with R-134a 

Because the refriger-
ant is at very high
pressure, the air con-
ditioning system
should only be serv-

iced by trained and certified
technicians. It is important that
the correct type and amount of
oil and refrigerant is used.
Otherwise, it may cause damage
to the vehicle and personal injury.

WARNING

Vehicles equipped with R-1234yf

Because the refrigerant is mildly
inflammable and at very high
pressure, the air conditioning
system should only be serviced
by trained and certified techni-
cians. It is important that the cor-
rect type and amount of oil and
refrigerant is used.
Otherwise, it may cause damage
to the vehicle and personal injury.
