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.

NOTICE
• Replace the filter according to the
Maintenance Schedule.
If the vehicle is being driven in
severe conditions such as dusty,
rough roads, more frequent cli-
mate control air filter inspections
and changes are required.
• When the air flow rate suddenly decreases, the system should be
checked at an authorized
HYUNDAI dealer.
Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is
low, the performance of the air con-
ditioning is reduced. Overfilling also
has a negative influence on the air
conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by
an authorized HYUNDAI dealer.
Air Conditioning refrigerant
label
The actual Air Conditioning refriger-
ant label in the vehicle may differ
from the illustration.
Each symbols and specification on
air conditioning refrigerant label
means as below ;
1. Classification of refrigerant
2. Amount of refrigerant
3. Classification of Compressor lubri-
cant
Refer to chapter 8 for more detail
location of air conditioning refrigerant
label.
WARNING
Because the refriger-
ant is at very high
pressure, the air con-
ditioning system
should only be serv-
iced by trained and certified
technicians. It is important that
the correct type and amount of
oil and refrigerant is used, oth-
erwise damage to the vehicle
and personal injury may occur.OHG045533N

AC inverter (if equipped)
The AC inverter supplies 115V/150W
electric power to operate electric
accessories or equipments.
(Continued)
Some electronic devices can cause electronic interferencewhen plugged into a vehicle’spower outlet. These devicesmay cause excessive audiostatic and malfunctions inother electronic systems ordevices used in your vehicle.
Make sure that the electric devices are plugged in secure-ly. If not, it could cause a mal-function of electric systems.
If you use an electric device with a battery, electric currentmay flow from the electricdevice into the vehicle andmay cause a malfunction ofelectric systems. Only useelectric devices which couldprevent inverse current.
WARNING
Do not put fingers or foreign
elements (pin, etc.) into a power
outlet and do not touch with a
wet hand. You may get an elec-
tric shock.
CAUTION
Use the power outlet only when the engine is runningand remove the accessoryplug after use. Using theaccessory plug for prolongedperiods of time with theengine off could cause thebattery to discharge.
Only use 10V electric acces- sories which are less than 10Ain electric capacity. If not, itcould lead to an overheatedpower outlet or electric wiringin the vehicle and electric sys-tems may malfunction.
Adjust the air-conditioner or heater to the lowest operatinglevel when using the poweroutlet.
Close the cover when not in use.

When the ECO mode is activated:
The acceleration response may be
slightly reduced.
The air conditioner performance may be limited.
The shift pattern of the automatic transaxle may change.
The engine noise may get louder.
The above situations are normal
conditions when the ECO mode is
activated to improve fuel efficiency.
Limitation of the ECO mode oper- ation:
If the following conditions occur while
ECO mode is operating, fuel efficien-
cy may decrease even though there
is no change in the ECO indicator.
When the coolant temperature is low:
Fuel efficiency may decrease until
engine temperature reaches nor-
mal.
When driving up a hill: Fuel efficiency may decrease to
gain performance when driving
uphill because engine torque is
restricted.
When using the automatic transaxle manual shift mode:
Fuel efficiency may decrease
according to the shift location.
When the accelerator pedal is deeply depressed for a few sec-
onds:
Fuel efficiency may decrease,
judging that the driver wants to
speed up.
SPORT mode
SPORT mode managesthe driving dynamics by
automatically adjusting the
steering wheel, engine
and transaxle system to
optimize performance.
When the SPORT mode is select- ed by pressing the DRIVE MODE
button, the SPORT indicator (yel-
low color) will illuminate.
Restarting of the engine in the SPORT mode resets the DRIVE
mode to the NORMAL mode. Thus,
when necessary, reselect the
SPORT mode.
When the SPORT mode is activat- ed:
- The RPM (revolutions per min-utes) level is maintained over a
certain length of time, even after
releasing the accelerator pedal.
- When accelerating, up-shifting timing is delayed.
✽ ✽ NOTICE
In the SPORT mode, the fuel effi-
ciency may decrease.

Active ECO operation
Active ECO helps improve fuel effi-
ciency by controlling certain engine
and transaxle system operating
parameters. Fuel efficiency depends
on the driver's driving habit and road
condition. When the Active ECO button is
pressed the ECO indicator (green)
will illuminate to show that the
Active ECO is operating.
When the Active ECO is activated, it will remain on until the Active
ECO button is pressed again.
Active ECO does not turn off when
the engine is restarted. To turn off
Active ECO, press the Active ECO
button again.
If Active ECO is turned off, the sys- tem will return to normal mode.When Active ECO is activated :
The engine noise may get louder.
The vehicle speed may slightly bereduced.
The air conditioner performance may be affected.
Limitation of Active ECO oper-
ation:
If the following conditions occur while
Active ECO is operating, the system
operation is limited even though there
is no change in the ECO indicator.
When the coolant temperature islow: The system will be limited until
engine performance becomes nor-
mal.
When driving up a hill: The system will be limited to gain power when
driving uphill because the engine
torque is restricted.
When using sports mode: The sys- tem will be limited according to the
shift location.
When the accelerator pedal is deeply depressed for a few sec-
onds: The system will be limited,
judging that the driver wants to
speed up.
