Air ventilation seat (if equipped)
The air ventilation seat is provided to
cool the front seats during hot weath-
er by blowing air through small vent
holes on the surface of the seats.
While the engine is running, press
the cooling portion (blue color) of the
switch to cool the driver's seat or the
front passenger's seat.
When the operation of the seat cool-
er is not needed, keep the switches
in the OFF position.
WARNING
The seat warmers can cause a
SERIOUS BURN, even at low
temperatures and especially if
used for long periods of time.
Passengers must be able to feel
if the seat is becoming too
warm so they can turn it off, if
needed.
People who cannot detect tem-
perature change or pain to the
skin should use extreme cau-
tion, especially the following
types of passengers:
Infants, children, elderly or
disabled persons, or hospital
outpatients.
People with sensitive skin or who burn easily.
Fatigued individuals.
Intoxicated individuals.
People taking medication that can cause drowsiness or
sleepiness.
WARNING
NEVER place anything on the
seat that insulates against heat
when the seat warmer is in
operation, such as a blanket or
seat cushion. This may cause
the seat warmer to overheat,
causing a burn or damage to
the seat.

Operation Tips
To prevent dust or unpleasant
fumes from entering the vehicle
through the ventilation system,
temporarily set the air intake con-
trol to the recirculated air position.
Be sure to return the control to the
fresh air position when the irritation
has passed to keep fresh air in the
vehicle. This will help keep the driv-
er alert and comfortable.
Air for the heating/cooling system is drawn in through the grilles just
ahead of the windshield. Care
should be taken that these are not
blocked by leaves, snow, ice or
other obstructions.
To prevent interior fog on the wind- shield, set the air intake control 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
HYUNDAI Air Conditioning Systems
are filled with environmentally friend-
ly 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 operating the air
conditioning system may create
water droplets inside the vehicle.
Since excessive water droplets
may cause damage to electrical
equipment, air conditioning
should only be used with the win-
dows closed.

Air conditioning system operation tips
If the vehicle has been parked indirect 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.
During the winter months, use the air conditioning system every
month for a few minutes to ensure
maximum system performance.
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 condensation is
a normal system operation charac-
teristic. 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 filter
replaced by an authorized HYUNDAI
dealer.

WINDSHIELD DEFROSTING AND DEFOGGING
For maximum defrosting, set thetemperature 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.
✽ ✽ NOTICE
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.

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.

Driving your vehicle
Chain installation
When installing chains, follow the
manufacturer's instructions and
mount them as tightly as you can.
Drive slowly with chains installed. If
you hear the chains contacting the
body or chassis, stop and tighten
them. If they still make contact, slow
down until it stops. Remove the
chains as soon as you begin driving
on cleared roads.Use high quality ethylene gly-
col 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 cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in section 7. Before winter,
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.
CAUTION
Chains that are the wrong sizeor improperly installed candamage your vehicle's brakelines, suspension, body andwheels.
Stop driving and retighten the chains any time you hear themhitting the vehicle.
WARNING- Tire chains
The use of chains may adversely affect vehicle han-
dling.
Do not exceed 20 mph (30 km/h) or the chain manufac-
turer's recommended speed
limit, whichever 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.
WARNING - Mounting
chains
When mounting snow chains,
park the vehicle on level ground
away from traffic. Turn on the
vehicle Hazard Warning flashers
and place a triangular emer-
gency warning device behind
the vehicle if available. Always
place the vehicle in P (Park),
apply the parking brake and
turn off the engine before
installing snow chains.

Driving your vehicle
Don't let your parking brake
freeze
Under some conditions your parking
brake can freeze in the engaged
position. This is most likely 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 the parking brake may
freeze, apply it only temporarily while
you put the shift lever in P (automat-
ic transaxle) and block the rear
wheels so the vehicle cannot roll.
Then release the parking brake.
Don't let ice and snow accu-
mulate underneath
Under some conditions, snow and
ice can build up under the fenders
and interfere with the steering. When
driving in severe winter conditions
where this may happen, you should
periodically check underneath the
vehicle to be sure the movement of
the front wheels and the steering
components is not obstructed.
Carry emergency equipment
Depending on the severity of the
weather, you should carry appropri-
ate emergency equipment. Some of
the items you may want to carry
include tire chains, tow straps or
chains, flashlight, emergency flares,
sand, a shovel, jumper cables, a win-
dow scraper, gloves, ground cloth,
coveralls or a blanket, etc.
Don't place foreign objects or
materials in the engine com-
partment
Placement of foreign objects or
materials which prevent cooling of
the engine, in the engine compart-
ment, may cause a failure or com-
bustion. The manufacturer is not
responsible for the damage caused
by such placement.

5119
Driving your vehicle
When you are ready to leave after
parking on a hill
1. With the automatic transaxle in P(Park), apply your brakes and hold
the brake pedal down while you:

and

2. Slowly remove your foot from the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance when trailer towing
Your vehicle will need service more
often when you regularly pull a trail-
er. Important items to pay particular
attention to include engine oil, auto-
matic transaxle fluid, axle lubricant
and cooling system fluid. Brake con-
dition is another important item to
frequently check. Each item is cov-
ered in this manual, and the Index
will help you find them quickly. If
you’re trailering, it's a good idea to
review these sections before you
start your trip.
Don't forget to also maintain your
trailer and hitch. Follow the mainte-
nance schedule that accompanied
your trailer and check it periodically.
Preferably, conduct the check at the
start of each day’s driving. Most
importantly, all hitch nuts and bolts
should be tight.WARNING- Parking
brake
It can be dangerous to get out
of your vehicle if the parking
brake is not firmly set.
If you have left the engine run-
ning, the vehicle can move sud-
denly. You or others could be
seriously or fatally injured.CAUTION
Due to higher load during trailer usage, overheatingmight occur in hot days orduring uphill driving. If thecoolant gauge indicates over-heating, switch off the A/C andstop the vehicle in a safe areato cool down the engine.
When towing check transaxle fluid more frequently.

What to do in an emergency
86
IF THE ENGINE OVERHEATS
If your temperature gauge indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine is probably too
hot. 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 and set the parking brake. If the air condi-
tioning is on, turn it off.
3. If engine coolant is running out under the car or steam is coming
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 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 car. (If the air condition-
ing had been in use, it is normal
for cold water to be draining from it
when you stop.)
5. If the water pump drive belt is bro- ken 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
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.
WARNING
While the engine is running,
keep hair, hands and clothing
away from moving parts such
as the fan and drive belts to pre-
vent injury.
CAUTION
Serious loss of coolant indi-cates there is a leak in the cool-ing system and this should bechecked as soon as possible byan authorized HYUNDAI dealer.
WARNING
Do not remove the radiator cap
when the engine is hot. This
may result in coolant being
blown out of the opening and
cause serious burns.
