Air conditioning system operation
tips
If the vehicle has been parked indirect sunlight during hot weather,
open the windows for a short time to
let the hot air inside the vehicle
escape.
After sufficient cooling has been achieved, switch back from the recir-
culated air to the fresh outside air
position.
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.
Use the air conditioning system every month only for a few minutes to
ensure maximum system perform-
ance.
If you operate air conditioner exces- sively, the difference between the
temperature of the outside air and
that of the windshield could cause the
outer surface of the windshield to fog
up, causing loss of visibility. In this
case, set the mode selection knob or
button to the position and fan
speed control to the lower speed.
System Maintenance
Climate control air filter
This filter is installed behind the
glove box. It filters the dust or other
pollutants that enter the vehicle
through the heating and air condi-
tioning system.
Have the climate control air filter
replaced by an authorized HYUNDAI
dealer according to the maintenance
schedule. If the car is being driven in
severe conditions such as dusty or
rough roads, more frequent air con-
ditioner filter inspections and
changes are required. If the air flow rate suddenly decreas-
es, the system should be checked at
an authorized HYUNDAI dealer.
Checking the amount of air
conditioner refrigerant andcompressor lubricant
When the amount of refrigerant is
low, the performance of the air con-
ditioning 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 HYUNDAI dealer.
It is important that the correct
type and amount of oil and refrig-
erant is used. Otherwise, damage
to the compressor and abnormal
system operation may occur.

should only be serv-

technicians. It is important that
the correct type and amount of
oil and refrigerant is used, oth-
erwise damage to the vehicle
and personal injury may occur.
