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 vehi-
cle by operating the air conditioning
system.
• During air conditioning system opera-
tion, you may occasionally notice a
slight 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.

Climate control air filter
(if equipped)
The climate control air filter installed
behind the glove box filters the dust or
other pollutants that come into the vehi-
cle 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 accumulation on the inside of
the windshield 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.

✽NOTICE
• Replace the filter every 15,000 km
(10,000 miles) or once a year.
If the car is being driven in severe
conditions such as dusty or rough
roads, more frequent air conditioner
filter inspections and changes are
required.
• When the air flow rate suddenly
decreases, the system should be
checked at an authorized HYUNDAI
dealer.
D230400AEN
Checking the amount of air con-
ditioner refrigerant and compres-
sor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning is
reduced. Overfilling also has a negative
impact on the air conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized HYUNDAI dealer.
✽NOTICE
It is important when servicing the air
conditioning system that the correct
type and amount of oil and refrigerant is
used. Otherwise, damage to the com-
pressor and abnormal system operation
may occur. D2301000BBH-EE
Rear vent
It will operate at the same time when you
operate the climate control system.
You can adjust the temperature by turn-
ing the temperature control knob. Turn
the knob to the red mark when warm air
is desired, or to the blue mark when cool
air is desired.
The outlet vents can be opened or closed
using the thumbwheel. To close the vent,
rotate it down (or left) to the maximum
position. To open the vent, rotate it up (or
right) to the desired position.
Also, you can adjust the direction of air
delivery from these vents using the vent
control lever as shown.
WARNING
The air conditioning system should
be serviced by an authorized
HYUNDAI dealer. Improper service
may cause serious injury to the
person performing the service.

Auto defogging system (if equipped)
Auto defogging reduces the probability 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 moisture
of inside the windshield and
operates.If more moisture is in the vehicle, the
higher steps operate as follow. For exam-
ple 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 :Blowing air toward the windshield
Step 3 : Increasing air flow toward the
windshield
Step 4 : Operating the air conditioning
Step 5 : Maximizing the air conditioning
If your vehicle is equipped with the auto
defogging system, it is automatically acti-
vated when the conditions are met.
However, if you would like to cancel the
auto defogging system, press the front
defroster button 4 times within 2 seconds
while pressing the AUTO button. The
indicator will blink 3 times to notify you
that the system is cancelled. To use the
auto defogging system again, follow the
procedures mentioned above.
If the battery has been disconnected or
discharged, it resets to the auto defog-
ging status.
✽NOTICE
• If the A/C off or recirculated air posi-
tion is manually selected while the
auto defogging system is on, the auto
defogging indicator will blink 3 times
to give notice that manual operation is
canceled.
• If the air quality system (AQS) is
selected while the auto defogging sys-
tem is operating at the step 1 outside
air position, the recirculated air posi-
tion may operate when the outside air
is polluted.

Driving your vehicle
60 5
• 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 plac-
ing 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 avoid-
ed by shifting at the recommended
speeds.• Use your air conditioning sparingly.
The air conditioning system is operat-
ed by engine power so your fuel econ-
omy 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 con-
dition is important both for economy and
safety. Therefore, have an authorized
HYUNDAI dealer perform scheduled
inspections and maintenance.
WARNING - Engine off dur-
ing 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 run-
ning. Instead, keep the engine on
and downshift to an appropriate
gear for engine braking effect. In
addition, 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
F050000ABH
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 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 con-
ditioning 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 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 system
and this should be checked as soon
as possible by an authorized
HYUNDAI dealer.
