Air conditioning
HYUNDAI Air Conditioning Systems
are filled with environmentally friendly
R-134a refrigerant.
1. Start the engine. Push the air con-
ditioning button.
2. Set the mode to the position.
3. Set the air intake control to the
recirculated air position. However,
prolonged operation of the recircu-
lated air position will excessively
dry the air. In this case, change the
air position.
4. Adjust the fan speed control and
temperature control to maintain
maximum comfort.
When maximum cooling is desired,
set the temperature control to the
extreme left position then set the
fan speed control to the highest
speed.
✽ ✽
NOTICE
• While using the air conditioning
system, monitor the engine tem-
perature gauge closely while driv-
ing up hills or in heavy traffic
when outside temperatures are
high. Air conditioning system
operation may cause engine over-
heating. Continue to use the blow-
er fan but turn the air condition-
ing system off if the engine tem-
perature gauge indicates engine
overheating.
• Opening the windows in humid
weather while air conditioning
operates may create water
droplets inside the vehicle. Since
excessive water droplets may
cause damage to electrical equip-
ment, air conditioning should only
be used 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.

Features of your vehicle
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 characteristic.
If you operate air conditioner
excessively, the difference
between the temperature of the
outside air and that of the wind-
shield could cause the outer sur-
face 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.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, have the climate control air fil-
ter 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 cli-
mate control air filter inspections
and changes are required.
• When the air flow rate suddenly
decreases, the system should be
checked at an authorized
HYUNDAI dealer.

WINDSHIELD DEFROSTING AND DEFOGGING
For maximum defrosting, set the
temperature control to the extreme
right/hot position and the fan speed
control to the highest speed.
If warm air to the floor is desired
while defrosting or defogging, set
the mode to the floor-defrost posi-
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.
✽ ✽
NOTE
Be sure to keep the interior surface
of the windshield clean by wiping it
with a clean cloth and glass cleaner.
This will help reduce the tendency of
the glass fogging and also improve
visibility.Manual climate control system
To defog inside windshield
1. Select any fan speed except “0”
position.
2. Select desired temperature, except
MAX A/C.
3. Select the or position.
4. The outside (fresh) air will be
selected automatically.
If the outside (fresh) air position is
not selected automatically, press the
corresponding button manually.
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
a lower speed.

uneven roads
- During severe rain (heavy rains,
windstorms)
• Phone related voice commands
can be used only when a
Bluetooth
®Wireless Technology
device is connected.
• When making calls by stating a
name, the corresponding contact
must be downloaded and stored
within the audio system.
• After downloading the Bluetooth
®
Wireless Technology phone book,
it takes some time to convert the
phone book data into voice infor-
mation. During this time, voice
recognition may not properly
operate.
• Pronounce the voice commands
naturally and clearly as if in a nor-
mal conversation.

If your temperature gauge indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine may be over-
heating. If this happens, you should:
1.Pull off the road and stop as soon
as it is safe to do so.
2.Place the shift lever in P (Park, for
automatic transaxle vehicle) or
neutral (for manual transaxle vehi-
cle) and set the parking brake. If
the air conditioning is ON, turn it
OFF.
3.If engine coolant is running out
under the vehicle or steam is com-
ing out from the hood, stop the
engine. Do not open the hood until
the coolant has stopped running or
the steaming has stopped. If there
is no visible loss of engine coolant
and no steam, leave the engine
running and check to be sure the
engine cooling fan is operating. If
the fan is not running, turn the
engine off.4.Check for coolant leaking from the
radiator, hoses or under the vehi-
cle. (If the air conditioning had
been in use, it is normal for cold
water to be draining from it when
you stop.)
5.If engine coolant is leaking out,
stop the engine immediately and
call an authorized HYUNDAI deal-
er for assistance.
IF THE ENGINE OVERHEATS
What to do in an emergency
8 6
WARNING
While the engine is
running, keep hands,
clothing and tools
away from the moving
parts such as the
cooling fan and drive
belt to prevent seri-
ous injury.
WARNING
NEVER remove the
radiator cap or the
drain plug while the
engine and radiator
are hot. Hot coolant
and steam may blow out under
pressure, causing serious
injury.
Turn the engine off and wait
until the engine cools down.
Use extreme care when remov-
ing the radiator cap. Wrap a
thick towel around it, and turn it
counterclockwise slowly to the
first stop. Step back while the
pressure is released from the
cooling system. When you are
sure all the pressure has been
released, press down on the
cap, using a thick towel, and
continue turning counterclock-
wise to remove it.

6.If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has been lost,
carefully add coolant to the reser-
voir to bring the fluid level in the
reservoir up to the halfway mark.
7.Proceed with caution, keeping
alert for further signs of overheat-
ing. If overheating happens again,
call an authorized HYUNDAI deal-
er for assistance.

What to do in an emergency
CAUTION
Serious loss of coolant indi-
cates a leak in the cooling
system and have the system
checked by an authorized
HYUNDAI dealer.
When the engine overheats
from low engine coolant, sud-
denly adding engine coolant
may cause cracks in the
engine. To prevent damage,
add engine coolant slowly in
small quantities.

Maintenance
Vacuum crankcase ventilation
hoses
Inspect the surface of hoses for evi-
dence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterio-
ration. Particular attention should be
paid to examine those hose surfaces
nearest to high heat sources, such
as the exhaust manifold.
Inspect the hose routing to assure
that the hoses do not come in con-
tact with any heat source, sharp
edges or moving component which
might cause heat damage or
mechanical wear. Inspect all hose
connections, such as clamps and
couplings, to make sure they are
secure, and that no leaks are pres-
ent. Hoses should be replaced
immediately if there is any evidence
of deterioration or damage.
Air cleaner filter
A genuine HYUNDAI air cleaner filter
is recommended when the filter is
replaced.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.
Cooling system
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Engine coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
