WARNING
 Continue using the climate con-
trol system in the recirculated air
position may allow humidity to
increase inside the vehicle which
may fog the glass and obscure
visibility.
 Do not sleep in a vehicle with the
air conditioning or heating sys-
tem on. It may cause serious
harm or death due to a drop in the
oxygen level and/or body temper-
ature.
 Continue using the climate con-
trol system in the recirculated 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 driv-

Features of your vehicle92 4Climate control air filterThe climate control air filter installed
behind the glove box filters the dust or
other pollutants that come into the vehi-
cle 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 accumulation on the inside of
the windshield even when the outside
(fresh) air position is selected. If this hap-
pens, have the climate control air filter
replaced by an authorized HYUNDAI
dealer.
✽ ✽
NOTICE• Replace the filter according to the
Maintenance Schedule.
If the vehicle is being driven in severe
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 HYUNDAI
dealer.
Checking the amount of air con-
ditioner refrigerant and compres-
sor lubricantWhen 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 HYUNDAI dealer.✽ ✽
NOTICEIt 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.
