Convenient Features5-110

 When the Remote Moving Forward
is ready by the above No. (1)
method, the vehicle recognizes the
condition as exit. After confirming
the surroundings within 13 ft. (4 m), it
allows to operate the steering wheel
up to the conditions ahead.

 When Remote Moving Forward is
ready by the above No. (2) method,
the vehicle recognizes the condition
as entering to the parking space.
According to the front condition, it
immediately allows the vehicle to
enter to the parking space and line
up with the steering wheel control.
However, the function performance
can be degraded up to the shape or
position of the surrounding objects.

 If you select the remote moving
backward, both of the No. (1) and (2)
methods make the vehicle go straight
after lining up.

 While Remote Moving Forward/
Backward assist is operating, the
brake light turns on.

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.
Fan speed control
ODN8A059113ODN8A059113
Turn the knob to the right to increase
the fan speed and airflow. Turn the knob
to the left to decrease fan speed and
airflow.
Setting the fan speed control knob to the
“0” position turns off the fan.
NOTICE
Operating the fan speed when the
ignition switch is in the ON position
could cause the battery to discharge.
Operate the fan speed when the engine
is running.
Air conditioning
ODN8059114ODN8059114
Push the A/C button to turn the system
on (indicator light will illuminate) and off.

Air conditioning system operation tips
• If the vehicle has been parked in dir
ect 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.
System Maintenance
Cabin air filter
OIK047401LOIK047401L[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.

NOTICE
Never place anything near the ambient
light/solar sensor to ensure better
control of the heating and cooling
system.
Manual Temperature Control
Mode
The heating and cooling system can be
controlled manually by pushing buttons
other than the AUTO button. In this case,
the system works sequentially according
to the order of buttons selected.
When pressing any button except the
AUTO button while using automatic
operation, the functions not selected will
be controlled automatically.
1. Start the engine.
2. Set the mode to the desired position.To improve the effectiveness of
heating and cooling, select the mode
according to the following: - Heating:
- Cooling:
3. Set the temperature control to the desired position.
4. Set the air intake control to Fresh mode position.
5. Set the fan speed control to the desired speed.
6. If air conditioning is desired, turn the air conditioning system on.
7. Press the AUTO button to convert to full automatic control of the system.
When starting the vehicle in cold
weather using manual temperature
control, operate the system in the
following method to improve heating.

- Turn off or lower the blower, right
after starting the engine.
- Allow the engine to warm up during this time since the air flow from the
heater is still cold.
- After a few minutes of engine warm up, turn on or set the fan to a higher
level and adjust the temperature
setting to hot.

- Using AUTO temperature control
mode set to 72 °F (22°C) will perform
the above steps automatically.
