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.

WARNING
- ENGINE EXHAUST CAN BE DANGEROUS!
Engine exhaust fumes can be extremely dangerous. If, at any time, you smell exhaust fumes inside the vehicle, open the win-
dows immediately.
• Do not inhale exhaust fumes.Exhaust fumes contain carbon monoxide, a colorless, odorless gas that can cause unconsciousness and death by asphyxia-
tion.
 Be sure the exhaust system does not leak. The exhaust system should be checked whenever the vehicle is raised to change the oil or for any other purpose. If you hear
a change in the sound of the exhaust or if you drive over something that strikes the underneath side of the car, have the
exhaust system checked as soon as possible by an authorized HYUNDAI dealer.
 Do not run the engine in an enclosed area. Letting the engine idle in your garage, even with the garage door open, is a hazardous practice. Never run the engine in your
garage any longer than it takes to start the engine and back the car out.
 Avoid idling the engine for prolonged periods with people inside the car. If it is necessary to idle the engine for a prolonged period with people inside the car, be sure to do so only in an open area
with the air intake set at "Fresh" and fan operating at one of the higher speeds so fresh air is drawn into the interior.
If you must drive with the trunk lid open because you are carrying objects that make this necessary:
1. Close all windows.
2. Open side vents.
3. Set the air intake control at "Fresh", the air flow control at "Floor" or "Face" and the fan at one of the higher speeds.
To assure proper operation of the ventilation system, be sure the ventilation air intakes located just in front of the windshield are
kept clear of snow, ice, leaves or other obstructions.
