Checking The Amount Of Air Conditioner - Hyundai Tucson 2020 Owner's Manual

The symbols and specifications on
the air conditioning refrigerant label
describe the:
1. Classification of refrigerant
2. Amount of refrigerant
3. Classification of Compressor lubri-
cant

cle on the label located inside of the

erant label.
Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is
low, the performance of the air con-
ditioning is reduced. Overfilling also
reduces the performance of the air
conditioning system.
Therefore, if abnormal operation is
found, we recommend that the sys-
tem be inspected by an authorised
HYUNDAI dealer.
WARNING
Vehicles equipped with R-134a
Because the refriger-
ant is at very high
pressure, the air con-
ditioning
should only be serv-
iced by trained and certified
technicians. It is important that
the correct type and amount of
oil and refrigerant are used.
Otherwise, it may cause dam-
age to the vehicle and personal
injury.
