✽NOTICE

conditions such as dusty, rough roads,
more frequent climate control air fil-
ter inspections and changes are
required.
• When the air flow rate suddenly decreases, the system should be
checked at an authorized KIA dealer.

Checking the amount of air con-
ditioner refrigerant and compres-
sor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning is
reduced. Overfilling also has a negative
influence on the air conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized KIA dealer.
✽ ✽ 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.
WARNING
The air conditioning system should
be serviced by an authorized KIA
dealer. Improper service may cause
serious injury to the person per-
forming the service.

partment will become stale.
In addition, prolonged operation of the
air conditioning with the recirculated
air position selected, will result in exces-
sively dry air in the passenger compart-
ment.
WARNING
Continuous use of the climate con-
trol system in the recirculated air
position may allow humidity to
increase inside vehicle which may
fog the glass and obscure visibility.
Do not sleep in a vehicle with air conditioning or heating system on.
It may cause serious harm or death
due to a drop in the oxygen level
and/or body temperature.
Continuous use of the climate con- trol system in the reciruclated air
position can cause drowsiness or
sleepiness, and loss of vehicle
control. Set the air intake control to
the outside (fresh) air position as
much as possible while driving.
