Air conditioning
All HYUNDAI Air Conditioning Systems
are filled with environmentally friendly
R-134a refrigerant which does not dam-
age the ozone layer.
1. Start the engine. Press the air condi-
tioning button.
2. Set the mode to the position.
3. Set the air intake control to the outside air or recirculated air position.
4. Adjust the fan speed control and tem- perature control to maintain maximum

✽✽ NOTICE
 When 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 over-
heating. Continue to use the blower
fan but turn the air conditioning sys-
tem 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 conditioning should only be run
with the windows closed.
Air conditioning system operation tips
If the vehicle has been parked in directsunlight 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 vehi-
cle by operating the air conditioningsystem.
During air conditioning system opera- tion, you may occasionally notice aslight change in engine speed as the
air conditioning compressor cycles.
This is a normal system operation
characteristic.
Use the air conditioning system every month only for a few minutes to ensure
maximum system performance. When using the air conditioning sys-
tem, you may notice clear water drip-
ping (or even puddling) on the ground
under the passenger side of the vehi-
cle. This is a normal system operation
characteristic.
Operating the air conditioning system in the recirculated air position provides
maximum cooling, however, 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 opera-
tion characteristics.

For maximum defrosting, set the tem-perature control to the extreme
right/hot position and the fan speedcontrol to the highest speed.
If warm air to the floor is desired while defrosting or defogging, set the modeto the floor-defrost position.
Before driving, clear all snow and ice from the windshield, rear window, out-
side rear view mirrors, and all side win-
dows.
Clear all snow and ice from the hood and air inlet in the cowl grill to improveheater and defroster efficiency and to
reduce the probability of fogging up theinside of the windshield.
To defog inside windshield
1. Set the fan speed to the desired posi- tion.
2. Select desired temperature.
3. Press the defrost button ( ).
4. The air conditioning will be turned on according to the detected ambient tem-
perature and outside (fresh) air posi-
tion will be selected automatically.
If the air conditioning and outside (fresh)air position are not selected automatical-
ly, adjust the corresponding button man-
ually. If the position is selected,
lower fan speed is adjusted to a higher
fan speed.
WINDSHIELD DEFROSTING AND DEFOGGING
WARNING - Windshield
heating
Do not use the or position during cooling operation in
extremely humid weather. The dif-
ference between the temperature ofthe 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 lowerspeed.

Use high quality ethylene glycol coolant
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 cooling system, lubri-
cates the water pump and prevents
freezing. Be sure to replace or replenish
your coolant in accordance with themaintenance schedule in section 7.
Before winter, have your coolant tested toassure 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 bat-
tery and cables as described in section
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 section 8
for recommendations. If you aren't sure
what weight oil you should use, consult
an authorized HYUNDAI dealer.
Check spark plugs and ignition system
Inspect your spark plugs as described in
section 7 and replace them if necessary.
Also check all ignition wiring and compo-
nents to be sure they are not cracked,
worn or damaged in any way.
WARNING
- Tire chains
The use of chains may adversely affect vehicle handling.
Do not exceed 30 km/h (20 mph) or the chain manufacturer’s rec-
ommended speed limit, whichev-
er is lower.
Drive carefully and avoid bumps, holes, sharp turns, and other
road hazards, which may cause
the vehicle to bounce.
Avoid sharp turns or locked- wheel braking.
CAUTION
Chains that are the wrong size or
improperly installed can damage
your vehicle's brake lines, sus-pension, body and wheels.
Stop driving and retighten the chains any time you hear themhitting the vehicle.

IF THE ENGINE OVERHEATS
If your temperature gauge indicates over-
heating, you experience a loss of power,
or hear loud pinging or knocking, the
engine is probably too hot. If this hap-
pens, 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 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 coming out
from the hood, stop the engine. Do notopen 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 operat-
ing. If the fan is not running, turn the
engine off. 4. Check to see if the water pump drive
belt is missing. If it is not missing,
check to see that it is tight. If the drive
belt seems to be satisfactory, check for
coolant leaking from the radiator,
hoses or under the vehicle. (If the air
conditioning had been in use, it is nor-
mal for cold water to be draining from
it when you stop).
5. If the water pump drive belt is broken or engine coolant is leaking out, stop the engine immediately and call the
nearest authorized HYUNDAI dealer
for assistance. 6. If you cannot find the cause of the
overheating, wait until the engine tem-
perature has returned to normal. Then,if coolant has been lost, carefully add
coolant to the reservoir to bring the
fluid level in the reservoir up to the
halfway mark.
7. Proceed with caution, keeping alert for further signs of overheating. If over-heating happens again, call an author-
ized HYUNDAI dealer for assistance.
WARNING
While the engine is running, keep
hair, hands and clothing away from
moving parts such as the fan and
drive belts to prevent injury.
WARNING
Do not remove the radiator cap
when the engine is hot. This can
allow coolant to be blown out of the
opening and cause serious burns.
CAUTION
Serious loss of coolant indicates there is a leak in the cooling systemand this should be checked as soonas possible by an authorized HYUNDAI dealer.
