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.

• 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.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
on according to the detected ambi-
ent temperature and outside
(fresh) air position will be selected
automatically.
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.

ding button manually. If the posi-
tion is selected, lower fan speed is
adjusted to a higher fan speed.To defrost outside windshield
1. Set the fan speed to the highest
position.
2. Set the temperature to the
extreme hot (HI) position.
3. Press the defrost button ( ).
4. The air conditioning will be turned
on according to the detected
ambient temperature and outside
(fresh) air position will be selected
automatically.
If the position is selected, lower
fan speed is adjusted to a higher fan
speed.
Defogging logic
To reduce the probability of fogging
up the inside of the windshield, the
air intake or air conditioning are con-
trolled automatically according to
certain conditions such as or
position. To cancel or return the
defogging logic, do the following.

1. Turn the ignition switch to the ON
position.
2. Press the defroster button ( ).
3. While pressing the air conditioning
button (A/C), press the air intake
control button at least 5 times with-
in 3 seconds.
The indicator on the air intake button
blinks 3 times with 0.5 seconds of
interval. It indicates that the defog-
ging logic is canceled or returned to
the programmed status.
If the battery has been discharged or
disconnected, it resets to the defog
logic status.
Auto defogging system
Auto defogging reduces the probabil-
ity of fogging up the inside of the
windshield by automatically sensing
the moisture of inside the windshield.
The auto defogging system operates
when the heater or air conditioning is
on.This indicator illuminates
when the auto defogging
system senses the mois-
ture of inside the wind-
shield and operates.
If more moisture is in the vehicle, the
higher steps operate as follow. For
example if auto defogging does not
defog inside the windshield at step 1
Outside air position, it tries to defog
again at step 2 Blowing air toward
the windshield.
Step 1 : Outside air position
Step 2 :Operating the air conditioning
Step 3 :Blowing air toward the wind-
shield
Step 4 : Increasing air flow toward
the windshield

Driving your vehicle
• Remember, your vehicle does not
require extended warm-up. After
the engine has started, allow the
engine to run for 10 to 20 seconds
prior to placing the vehicle in gear.
In very cold weather, however, give
your engine a slightly longer warm-
up period.
• Don't "lug" or "over-rev" the engine.
Lugging is driving too slowly in too
high a gear resulting in the engine
bucking. If this happens, shift to a
lower gear. Over-revving is racing
the engine beyond its safe limit.
This can be avoided by shifting at
the recommended speeds.
• Use your air conditioning sparingly.
The air conditioning system is
operated by engine power so your
fuel economy is reduced when you
use it.
• Open windows at high speeds can
reduce fuel economy.
• Fuel economy is less in crosswinds
and headwinds. To help offset
some of this loss, slow down when
driving in these conditions.Keeping a vehicle in good operating
condition is important both for econ-
omy and safety. Therefore, we rec-
ommend that the system be serviced
by an authorized HYUNDAI dealer.
WARNING - Engine off
during
motion
Never turn the engine off to
coast down hills or anytime the
vehicle is in motion. The power
steering and power brakes will
not function properly without
the engine running. Instead,
keep the engine on and down-
shift to an appropriate gear for
engine braking effect. In addi-
tion, turning off the ignition
while driving could engage the
steering wheel lock resulting in
loss of vehicle steering which
could cause serious injury or
death.

What to do in an emergency

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 soon
as 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 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 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 satis-
factory, check for coolant leaking
from the radiator, hoses or under
the vehicle. (If the air conditioning
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, we recommend that you 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,
we recommend that you call an
authorized 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 pre-
vent injury.
CAUTION
• Serious loss of coolant indi-
cates there is a leak in the
cooling system and we recom-
mend that the system be
checked as soon as possible
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.
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.

Maintenance
OWNER MAINTENANCE
The following lists are vehicle checks
and inspections that should be per-
formed at the frequencies indicated
to help ensure safe, dependable
operation of your vehicle.
Any adverse conditions should be
brought to the attention of your deal-
er as soon as possible.
These Owner Maintenance Checks
are generally not covered by war-
ranties and you may be charged for
labor, parts and lubricants used.Owner maintenance schedule
When you stop for fuel:
• Check the engine oil level.
• Check coolant level in coolant
reservoir.
• Check the windshield washer fluid
level.
• Look for low or under-inflated tires.
While operating your vehicle:
• Note any changes in the sound of
the exhaust or any smell of
exhaust fumes in the vehicle.
• Check for vibrations in the steering
wheel. Notice any increased steer-
ing effort or looseness in the steer-
ing wheel, or change in its straight-
ahead position.
• Notice if your vehicle constantly
turns slightly or “pulls” to one side
when traveling on smooth, level
road.
• When stopping, listen and check
for unusual sounds, pulling to one
side, increased brake pedal travel
or “hard-to-push” brake pedal.
• If any slipping or changes in the
operation of your transmission
occurs, check the transmission
fluid level.
• Check automatic transmission P
(Park) function.
• Check parking brake.
• Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal).
WARNING
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot
coolant and steam may blow
out under pressure. This could
cause burns or other serious
injury.
