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.
• After sufficient cooling has been
achieved, switch back from the
recirculated air to the fresh outside air position.
• 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 with the windows
and sunroof closed.
• Use the air conditioning system
every month only for a few minutes
to ensure maximum system
performance.
• If you operate air conditioner
excessively, the difference between
the temperature of the outside air and
that of the windshield could cause
the outer surface 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.

Cabin air filter
OIK047401L
[A] : Outside air, [B] : Recirculated air
[C] : Cabin air filter, [D] : Blower
[E] : Evaporator core, [F] : Heater core
The cabin air filter is installed behind
the glove box. It filters the dust or other
pollutants that enter the vehicle through
the heating and air conditioning system.
Have the cabin air filter replaced by an
authorized HYUNDAI dealer according to
the maintenance schedule. If the vehicle
is being driven in severe conditions such
as dusty or rough roads, more frequent
cabin air filter inspections and changes
are required.
If 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 conditioning
is reduced. Overfilling also reduces the
performance of the air conditioning
system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized HYUNDAI dealer.

With the outside (fresh) air
position selected, air enters
the vehicle from outside and
is heated or cooled according
to the function selected.
Information
Using the system primarily in Fresh mode
and Recirculation mode only when needed
is recommended for best results.
Prolonged operation of the heater in
Recirculation mode and without the A/C ON can cause fogging of the windshield.
In addition, prolonged use of the A/C
ON in Recirculation mode may result in
excessively dry, dehumidified air in the cabin.
WARNING
• Continued use of the climate control
system operation in Recirculation
mode for a prolonged period of
time may cause drowsiness to the
occupants in the cabin. This may lead
to loss of vehicle control which may
lead to an accident.
• Continued use of the climate control
system operation in Recirculation
mode with the A/C OFF may allow
humidity to increase inside the
cabin. This may cause condensation
to accumulate on the windshield and
obscure visibility.
• Do not sleep in your vehicle or
remain parked in your vehicle with
the windows up and either the
heater or the air conditioning ON for
prolonged periods of time. Doing so
may increase the levels of carbon
dioxide in the cabin which may lead
to serious injury or death.

WARNING
Carbon monoxide (CO) gas is toxic. Breathing CO can cause unconsciousness and
death.
Engine exhaust contains carbon monoxide which cannot be seen or smelled.
Do not inhale engine exhaust.
If at any time you smell engine exhaust inside the vehicle, open the windows
immediately. Exposure to CO can cause unconsciousness and death by asphyxiation.
Be sure the exhaust system does not leak.
The exhaust system should be checked whenever the vehicle is raised to change the
oil or for any other purpose. If you hear a change in the sound of the exhaust or if you
drive over something that strikes the underneath side of the vehicle, have the exhaust
system checked as soon as possible by an authorized HYUNDAI dealer.
Do not run the engine in an enclosed area.
Letting the engine idle in your garage, even with the garage door open, is a hazardous
practice. Run the engine only long enough to start the engine and to move the vehicle
out of the garage.
Avoid idling the engine for prolonged periods with people inside the vehicle.
If it is necessary to idle the engine for a prolonged period with people inside the
vehicle, be sure to do so only in an open area with the air intake set at "Fresh" and fan
control set to high so fresh air is drawn into the interior.
Keep the air intakes clear.
To assure proper operation of the ventilation system, keep the ventilation air intakes
located in front of the windshield clear of snow, ice, leaves, or other obstructions.
If you must drive with the trunk open:
Close all windows.
Open instrument panel air vents.
Set the air intake control at "Fresh", the air flow control at "Floor" or "Face", and the fan
control set to high.

shift up or down one gear and the system
changes from automatic shift mode to manual shift mode.
To change back to the automatic shift
mode from manual shift mode, do one of
the following: • Gently depress the accelerator pedal
for more than 5 seconds.
• Drive the vehicle under 10 km/h (6
mph).
• Pull and hold the right side paddle
shifter.

•
The dual clutch transmission can be
thought of as an automatically shifting
manual transmission. It gives the
driving feel of a manual transmission,
yet provides the ease of a fully
automatic transmission.
• When D (Drive) is selected, the
transmission will automatically
shift through the gears similar to a
conventional automatic transmission.
Unlike a traditional automatic
transmission, the gear shifting can
sometimes be felt and heard as the
actuators engage the clutches and the
gears are selected.
• The dual clutch transmission
incorporates a wet-type dual clutch
mechanism, which allows for better
acceleration performance and
increased fuel efficiency while driving.
But it differs from a conventional
automatic transmission because
it does not incorporate a torque
converter. Instead, the transition from
one gear to the next is managed by
clutch slip, especially at lower speeds.
As a result, shifts are sometimes more
noticeable, and a light vibration can
be felt as the transmission shaft speed
is matched with the engine shaft
speed. This is a normal condition of
the dual clutch transmission.
• The wet-type clutch transfers torque
more directly and provides a direct-
drive feeling which may feel different
from a conventional automatic
transmission. This may be more
noticeable when launching the vehicle
from a stop or when traveling at low,
stop-and-go vehicle speeds. •
When rapidly accelerating from a
lower vehicle speed, the engine
rpm may increase dramatically as a
result of clutch slip as the dual clutch
transmission selects the correct gear. This is a normal condition.
• When accelerating from a stop on
an incline, press the accelerator
smoothly and gradually to avoid any
shudder feeling or jerkiness.
• When traveling at a lower vehicle
speed, if you release the accelerator
pedal quickly, you may feel engine
braking before the transmission
changes gears. This engine braking
feeling is similar to operating a
manual transmission at low speed.
• When driving downhill, you may wish
to move the gear shift lever/button to
Manual Shift mode and downshift to
a lower gear in order to control your
speed without using the brake pedal
excessively.
• When you turn the engine on and off,
you may hear clicking sounds as the
system goes through a self-test. This
is a normal sound for the dual clutch
transmission.
• During the first 1,500 km (1000 miles),
you may feel that the vehicle may not
be smooth when accelerating at low
speed. During this break-in period, the
shift quality and performance of your
new vehicle is continuously optimized.

Parking
Always come to a complete stop and
continue to depress the brake pedal.
Move the shift lever/button into the P
(Park) position, apply the parking brake,
and place the ignition switch in the
LOCK/OFF position. Take the Key with
you when exiting the vehicle.
WARNING
When you stay in the vehicle with
the engine running, be careful not to
depress the accelerator pedal for a long
period of time. The engine or exhaust
system may overheat and start a fire.
The exhaust gas and the exhaust system
are very hot. Keep away from the
exhaust system components.
Do not stop or park over flammable
materials, such as dry grass, paper or
leaves. They may ignite and cause a fire.
