Operation Tips• To keep dust or unpleasant fumes from entering the car through the
ventilation system, temporarily set
the air intake control to the recircu-
lated air position. Return the con-
trol to the fresh air position when
the irritation has passed. This will
help keep the driver alert and com-
fortable.
• To prevent inside of the windshield from fogging, set the air intake con-
trol to the fresh air position and fan
speed to the desired position, turn
on the air conditioning system, and
adjust the temperature control to
desired temperature.
Air conditioning (if equipped) HYUNDAI Air Conditioning Systems
are filled with a R-134a refrigerant.
1. Start the engine.
2. Push the air conditioning button.
3. Set the mode to the Face Level mode.
4. 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.
5. Adjust the fan speed control and temperature control to maintain
maximum comfort.
When maximum cooling is desired,
set the temperature control to the
lowest setting (LO) then set the fan
speed control to the highest speed.

WWhen using the air conditioning sys-
tem, monitor the temperature gauge
closely while driving up hills or in
heavy traffic when outside tempera-
tures are high. Air conditioning sys-
tem operation may cause engine
overheating. Continue to use the
blower fan but turn the air condition-
ing system off if the engine tempera-
ture gauge indicates engine over-
heating.
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.
• After sufficient cooling has been achieved, switch back from the
recirculated air to the fresh outside
air position.
• 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 with the win-
dows closed.
• Use the air conditioning system every month only for a few minutes
to ensure maximum system per-
formance. • If you operate air conditioner
excessively, the difference between
the temperature of the outside air
and that of the windshield could
cause the outer surface 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.

We recommend the air conditioning
system be serviced by an authorized
HYUNDAI dealer.
WWindshield defrosting and defog-
ging
• 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 at the buttom of
the windshield.
• If the engine temperature is still cold after starting, then a brief
engine warm up period may be
required for the vented air flow to
become warm or hot.
Because the refrigerant
is at very high pressure,
the air conditioning sys-
tem should only be serv-
iced by trained and certi-
fied technicians. It is important that
the correct type and amount of oil
and refrigerant is used, otherwise
damage to the vehicle and personal
injury may occur.WARNING
Do not use the or position
during cooling operation in
extremely humid weather. The dif-
ference between the temperature
of the outside air and that of the
windshield could cause the outer
surface of the windshield to fog
up, causing loss of visibility. Set
the mode selection to the
position and fan speed control to a
lower speed.
WARNING

When using tire chains:
• Wrong size chains or improperlyinstalled chains can damage your
vehicle's brake lines\b suspension\b
body and wheels.
• Use SAE “S” class or wire chains.
• If you hear noise caused by chains contacting the body\b retighten the
chain to prevent contact with the
vehicle body.
• To prevent body damage\b retighten the chains after driving \f.5~1.\f km
(\f.3~\f.6 miles).
• Do not use tire chains on vehic
les
equipped with aluminum wheels. If
unavoidable\b use a wire type
chain.
• Use wire chains less than 15 mm (\f.59 in) wide to prevent damage
to the chain’s connection.
Winter precautions
Use high quality ethylene glycolcoolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because
it helps prevent corrosion in the cool
ing system\b lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in chapter 7. Before winter\b
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.
Check battery and cables
Winter puts additional burdens on
the battery system. Visually inspect
the battery and cables as described
in chapter 7. The level of charge in
your battery can be checked by an
authorized HYUNDAI dealer or a
service station.
Change to "winter weight" oil if necessary
In some climates it is recommended
that a lower viscosity "winter weight"
oil be used during cold weather. See
chapter 8 for recommendations. If
you aren't sure what weight oil you
should use\b we recommend that you
consult with an authorized HYUNDAI
dealer.
Check spark plugs and ignition system
Inspect your spark plugs as
described in chapter 7 and replace
them if necessary. Also check all
ignition wiring and components to be
sure they are not cracked\b worn or
damaged in any way.

To keep locks from freezing
To keep the locks from freezing\b
squirt an approved deicer fluid or
glycerine into the key opening. If a
lock is covered with ice\b squirt it with
an approved deicing fluid to remove
the ice. If the lock is frozen internally\b
you may be able to thaw it out by
using a heated key. Handle the heat
ed key with care to avoid injury.
Use approved window washerantifreeze in system
To keep the water in the window
washer system from freezing\b add an
approved window washer antifreeze
solution in accordance with instruc
tions on the container. Window wash
er antifreeze is available from an
authorized HYUNDAI dealer and
most auto parts outlets. Do not use
engine coolant or other types of anti
freeze as these may damage the
paint finish.
Don't let your parking brake freeze
Under some conditions your parking
brake can freeze in the engaged
position. This is most likely to hap
pen 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 the parking brake
may freeze\b apply it only temporarily
while you put the shift lever in P (for
Automatic Transaxle/Continuously
Variable Transaxle) or in first or
reverse gear (for Manual Transaxle)
and block the rear wheels so the
vehicle cannot roll. Then release the
parking brake.
Don't let ice and snow accumulate underneath
Under some conditions\b snow and
ice can build up under the fenders
and interfere with the steering. When
driving in severe winter conditions
where this may happen\b you should
periodically check underneath the
car to be sure the movement of the
front wheels and the steering com
ponents is not obstructed.
Carry emergency equipment
Depending on the severity of the
weather\b you should carry appropri
ate emergency equipment. Some of
the items you may want to carry
include tire chains\b tow straps or
chains\b flashlight\b emergency flares\b
sand\b shovel\b jumper cables\b window
scraper\b gloves\b ground cloth\b cover
alls\b blanket\b etc.
Don't place foreign objects or materials in the engine compartment
Placement of foreign objects or
materials which prevent cooling of
the engine\b in the engine compart
ment\b may cause a failure or com
bustion. The manufacturer is not
responsible for the damage caused
by such placement.

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 soonas it is safe to do so.
2.Place the shift lever in P (Park, for Continuously Variable Transaxle
vehicle) or neutral (for Manual
Transaxle vehicle) and set the
parking brake. If the air condition-
ing 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
we recommend that you call an
authorized HYUNDAI dealer for
assistance.$$ !%%#$#%% %"!!!$#'#"'"' %'$%'&&&%
While the engine is run-
ning, keep hands,
clothing and tools away
from the moving parts
such as the cool ing fan
and drive belt to pre-
vent serious injury.WARNING
NEVER remove the
radiator cap or the
drain plug while the
engine and radiator are
hot. Hot coolant and
ste am may blow out under pres-
sure, causing serious injury.
Turn the engine off and wait until
the engine cools down. Use
extreme care when removing the
radiator cap. Wrap a thick towel
around it, and turn it c ounterclock-
wise slowly to the first stop. Step
back while the pressure is
released from the cooling sy stem.
When you are sure all the pres-
sure has been released, press
down on the cap, using a thick
towel, and continue turning coun-
terclockwise to remove it.WARNING

6.If you cannot find the cause of theoverheating, 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,
we recommend that you call an
authorized HYUNDAI dealer for
assistance. •
•
Serious loss of coolant indicates a
leak in the cooling system and we
recommend the system be
checked b y an authorized
HYUNDAI dealer.
• When the engine overheats from low engine coolant, suddenly
adding engin e coolant may cause
cracks in the engine. To prevent
damage, add engine coolant slow-
ly in small quanti ties.NOTICE
