Air conditioning
HYUNDAI Air Conditioning Systems
are filled with environmentally friend-
ly refrigerant.
1. Start the engine. Press the air con-
ditioning button.
2. Set the mode to the position.
3. Set the air intake control to the
outside air or recirculated air posi-
tion.
4. Adjust the fan speed control and
temperature control to maintain
maximum comfort.
✽NOTICE
• When using the air conditioning
system, monitor the temperature
gauge closely while driving up
hills or in heavy traffic when out-
side temperatures are high. Air
conditioning system operation
may cause engine overheating.
Continue to use the blower fan but
turn the air conditioning system
off if the temperature gauge indi-
cates engine overheating.
• When opening the windows in
humid weather air conditioning
may create water droplets inside
the vehicle. Since excessive water
droplets may cause damage to
electrical equipment, air condi-
tioning should only be run with
the windows closed.
Air conditioning system operation tips
• If the vehicle has been parked in
direct sunlight during hot weather,
open the windows for a short time
to let the hot air inside the vehicle
escape.
• To help reduce moisture inside of
the windows on rainy or humid
days, decrease the humidity inside
the vehicle by operating the air
conditioning system.
• During air conditioning system
operation, you may occasionally
notice a slight change in engine
speed as the air conditioning com-
pressor cycles. This is a normal
system operation characteristic.
• Use the air conditioning system
every month only for a few minutes
to ensure maximum system per-
formance.

• When using the air conditioning
system, you may notice clear water
dripping (or even puddling) on the
ground under the passenger side
of the vehicle. This is a normal sys-
tem operation characteristic.
• Operating the air conditioning sys-
tem in the recirculated air position
provides maximum cooling, how-
ever, continual operation in this
mode may cause the air inside the
vehicle to become stale.
• During cooling operation, you may
occasionally notice a misty air flow
because of rapid cooling and
humid air intake. This is a normal
system operation characteristics.Climate control air filter
The climate control air filter installed
behind the glove box filters the dust
or other pollutants that come into the
vehicle 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 accu-
mulation on the inside of the wind-
shield even when the outside (fresh)
air position is selected. If this hap-
pens, we recommend that the cli-
mate control air filter be replaced by
an authorized HYUNDAI dealer.
✽NOTICE
• Replace the filter according to the
Maintenance Schedule.
If the car is being driven in severe
conditions such as dusty, rough
roads, more frequent climate con-
trol air filter inspections and
changes are required.
• When the air flow rate suddenly
decreases, we recommend that the
system be checked by an author-
ized HYUNDAI dealer.

Defogging logic
To reduce the probability of fogging
up the inside of the windshield, the
air intake or air conditioning are con-
trolled automatically according to
certain conditions such as or
position. To cancel or return the
defogging logic, do the following.

1. Turn the ignition switch to the ON
position.
2. Press the defroster button ( ).
3. While pressing the air conditioning
button (A/C), press the air intake
control button at least 5 times with-
in 3 seconds.
The indicator on the air intake button
blinks 3 times with 0.5 seconds of
interval. It indicates that the defog-
ging logic is canceled or returned to
the programmed status.
If the battery has been discharged or
disconnected, it resets to the defog
logic status.
Auto defogging system
Auto defogging reduces the probabil-
ity of fogging up the inside of the
windshield by automatically sensing
the moisture of inside the windshield.
The auto defogging system operates
when the heater or air conditioning is
on.This indicator illuminates
when the auto defogging
system senses the mois-
ture of inside the wind-
shield and operates.
If more moisture is in the vehicle, the
higher steps operate as follow. For
example if auto defogging does not
defog inside the windshield at step 1
Outside air position, it tries to defog
again at step 2 Blowing air toward
the windshield.
Step 1 : Outside air position
Step 2 :Operating the air conditioning
Step 3 :Blowing air toward the wind-
shield
Step 4 : Increasing air flow toward
the windshield

Driving your vehicle
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 windows immediately.
• Do not inhale exhaust fumes.
Exhaust fumes contain carbon monoxide, a colorless, odorless gas that can cause unconsciousness and death
by asphyxiation.
• 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, we recommend that the system be checked 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.

EMISSION CONTROL SYSTEM (IF EQUIPPED)
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty
information contained in the Service
Passport in your vehicle.
Your vehicle is equipped with an
emission control system to meet all
applicable emission regulations.
There are three emission control
systems, as follows.
(1) Crankcase emission control sys-
tem
(2) Evaporative emission control
system
(3) Exhaust emission control system
In order to assure the proper function
of the emission control systems, it is
recommended that you have your
car inspected and maintained by an
authorized HYUNDAI dealer in
accordance with the maintenance
schedule in this manual.Caution for the Inspection and
Maintenance Test (With Electronic
Stability Contol (ESC) system)
• To prevent the vehicle from mis-
firing during dynamometer test-
ing, turn the Electronic Stability
Contol (ESC) system off by
pressing the ESC switch.
• After dynamometer testing is
completed, turn the ESC system
back on by pressing the ESC
switch again.1. Crankcase emission control
system
The positive crankcase ventilation
system is employed to prevent air
pollution caused by blow-by gases
being emitted from the crankcase.
This system supplies fresh filtered air
to the crankcase through the air
intake hose. Inside the crankcase,
the fresh air mixes with blow-by
gases, which then pass through the
PCV valve into the induction system.
2. Evaporative emission control
system
The Evaporative Emission Control
System is designed to prevent fuel
vapors from escaping into the atmos-
phere.
