Recirculated air position
With the recirculated air
position selected, air from
the passenger compart-
ment will be drawn through
the heating system and
heated or cooled according
to the function selected.
Outside (fresh) air position
With the outside (fresh) air
position selected, air
enters the vehicle from out-
side and is heated or
cooled according to the
function selected.✽NOTICE
Prolonged operation of the heater in
the recirculated air position (with-
out air conditioning selected) may
cause fogging of the windshield and
side windows and the air within the
passenger compartment may
become stale.
In addition, prolonged use of the air
conditioning with the recirculated
air position selected will result in
excessively dry air in the passenger
compartment.WARNING
• Continued climate control
system operation in the recir-
culated 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
system on. It may cause seri-
ous harm or death due to a
drop in the oxygen level
and/or body temperature.
• Continued climate control sys-
tem operation in the recirculat-
ed 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.

Air quality system
The air inflow from outside the vehi-
cle can be automatically controlled.
Press the button to activate the air
quality control system.
When using AQS mode, AQS(Air
Quality System) automatically sens-
es outdoor air pollutants and mini-
mizes them from entering the vehi-
cle, however, unpleasant or foul
odors that might be present may still
be noticeable within the vehicle.Exhaust gas cutoff mode :
Air enters the vehicle from the outside.
If exhaust gas enters the vehicle from
the outside, the exhaust gas cutoff
mode is automatically converted from
the outside air position to the recircu-
lated air position to prevent exhaust
gas from entering the vehicle.
✽NOTICE
It should be noted that prolonged
operation of the heating system in
recirculation mode will give rise to
misting of the windshield and side
windows and the air within the pas-
senger compartment will become
stale. In addition, prolonged use of
the air conditioning with the recir-
culation mode selected may result in
the air within the passenger com-
partment becoming excessively dry.

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.

tion.
• Before driving, clear all snow and
ice from the windshield, rear win-
dow, outside rear view mirrors, and
all side windows.
• Clear all snow and ice from the
hood and air inlet in the cowl grill to
improve heater and defroster effi-
ciency and to reduce the probabili-
ty of fogging up the inside of the
windshield.To defog inside windshield
1. Set the fan speed to the desired
position.
2. Select desired temperature.
3. Press the defrost button ( ).
4. The air conditioning will be turned

WINDSHIELD DEFROSTING AND DEFOGGING
WARNING - Windshield
heating
Do not use the or posi-
tion during cooling operation in
extremely humid weather. The
difference between the temper-
ature of the outside air and that
of the windshield could cause
the outer surface of the wind-
shield to fog up, causing loss of
visibility. In this case, set the
mode selection knob or button
to the position and fan
speed control knob or button to
the lower speed.

Driving your vehicle
• Don't coast down hills with the
vehicle out of gear. This is extreme-
ly hazardous. Keep the car in gear
at all times, use the brakes to slow
down, then shift to a lower gear so
that engine braking will help you
maintain a safe speed.
• Don't "ride" the brake pedal.
Resting your foot on the brake
pedal while driving can be danger-
ous because it can result in the
brakes overheating and losing their
effectiveness. It also increases the
wear of the brake components.
• If a tire goes flat while you are driv-
ing, apply the brakes gently and
keep the car pointed straight
ahead while you slow down. When
you are moving slowly enough for it
to be safe to do so, pull off the road
and stop in a safe place.• If your vehicle is equipped with an
automatic transmission, don't let
your car creep forward. To avoid
creeping forward, keep your foot
firmly on the brake pedal when the
car is stopped.
• Be caution when parking on a hill.
Firmly engage the parking brake
and place the shift lever in P. If your
vehicle is facing downhill, turn the
front wheels into the curb to help
keep the vehicle from rolling. If
your vehicle is facing uphill, turn
the front wheels away from the
curb to help keep the vehicle from
rolling. If there is no curb or if it is
required by other conditions to
keep the vehicle from rolling, block
the wheels.• Under some conditions your park-
ing brake can freeze in the
engaged position. This is most like-
ly to happen when there is an
accumulation of snow or ice
around or near the rear brakes or if
the brakes are wet. If there is a risk
that the parking brake may freeze,
apply it only temporarily while you
put the shift lever in P and block
the rear wheels so the car cannot
roll. Then release the parking
brake.
• Do not hold the vehicle on the
upgrade with the accelerator
pedal. This can cause the trans-
mission to overheat. Always use
the brake pedal or parking brake.

Hazardous driving conditions
When hazardous driving conditions
are encountered such as water,
snow, ice, mud, sand, or similar haz-
ards, follow these suggestions:
• Drive cautiously and allow extra
distance for braking.
• Avoid sudden movements in brak-
ing or steering.• If stalled in snow, mud, or sand,
use second gear. Accelerate slow-
ly to avoid spinning the drive
wheels.
• Use sand, rock salt, tire chains, or
other non-slip material under the
drive wheels to provide traction
when stalled in ice, snow, or mud.
Rocking the vehicle
If it is necessary to rock the vehicle
to free it from snow, sand, or mud,
first turn the steering wheel right and
left to clear the area around your
drive wheels. Then, shift back and
forth between R (Reverse) and any
forward gear in vehicles equipped
with an automatic transmission. Do
not race the engine, and spin the
wheels as little as possible. If you are
still stuck after a few tries, have the
vehicle pulled out by a tow vehicle to
avoid engine overheating and possi-
ble damage to the transmission.
SPECIAL DRIVING CONDITIONS
OVI053043
WARNING- ABS
Do not pump the brake pedal on
a vehicle equipped with ABS.
WARNING
- Downshifting
Downshifting with an automatic
transmission, while driving on
slippery surfaces can cause an
accident. The sudden change in
tire speed could cause the tires
to skid. Be careful when down-
shifting on slippery surfaces.
CAUTION
Prolonged rocking may cause
engine over-heating, transmis-
sion damage or failure, and tire
damage.
