Engine coolant temperature gauge
ODN8A049041ODN8A049041
ODN8A049006ODN8A049006This gauge indicates the temperature
of the engine coolant when the ignition
switch is in the ON position.
NOTICE
If the gauge pointer moves beyond
the normal range area toward the "H"
position, it indicates overheating that
may damage the engine.
Do not continue driving with an
overheated engine. If your engine
overheats, refer to "If the Engine
Overheats" in chapter 7.
WARNING
Never remove the radiator cap or
reservoir cap when the engine is hot.
The engine coolant is under pressure
and could severely burn. Wait until the
engine is cool before adding coolant to
the reservoir.
Fuel gauge
ODN8A049040ODN8A049040
ODN8A049007ODN8A049007This gauge indicates the approximate
amount of fuel remaining in the fuel tank.
Information
• The fuel tank capacity is given in
chapter 2.
• The fuel gauge is supplemented by
a low fuel warning light, which will
illuminate when the fuel tank is nearly
empty.
• On inclines or curves, the fuel gauge
pointer may fluctuate or the low fuel
warning light may come on earlier than
usual due to the movement of fuel in
the tank.

Heating and Air Conditioning
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 or recirculation mode position.
5. Set the fan speed control to the desired speed.
6. If air conditioning is desired, turn the air conditioning system on.
When starting the vehicle in cold weather
a more efficient way to heat the passen-
ger compartment is to do the following.

- Turn off or lower the blower, right
after starting the engine.
- Engine temperature is still low and 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 with adjust the temperature
setting to hot.

Convenient Features5-124
System Operation
Cooling / Ventilation
1. Select the Face Level mode.
2. Set the air intake control to fresh mode.
3. Set the temperature control to the desired position.
4. Set the fan speed control to the desired speed.
Heating
1. Select the Floor Level mode.
2. Set the air intake control to fresh mode.
3. Set the temperature control to the desired position.
4. Set the fan speed control to the desired speed.
5. If desired, turn the air conditioning ON with the temperature control knob set
to heat in order to dehumidify the air
before it enters into the cabin.
If the windshield fogs up, select the Floor
& Defrost
mode or press the Front
Defrost mode.
Operation Tips
• To keep dust or unpleasant fumes fr
om entering the vehicle through the
ventilation system, temporarily set
the air intake control to recirculation
mode. Return the control to Fresh
mode when the unpleasant air outside
has diminished. This will help keep the
driver alert and comfortable.
• To help prevent the inside of the windshield from fogging, set the air
intake control to fresh mode and fan
speed to the desired position, turn
on the air conditioning system, and
adjust the temperature control to the
desired temperature.
Air conditioning
Your HYUNDAI vehicle air conditioning
system is filled with R-1234yf refrigerant.
1. Start the engine.
2. Press the air conditioning button.
3. Set the mode to the Face Level

mode.
4. Set the air intake control to Recirculation mode temporarily to
allow the cabin to cool quickly. When
the desired temperature in the cabin
is reached, change the air intake
control back to Fresh mode.
5. Adjust the fan speed control and temperature control to maintain
maximum comfort.
When maximum cooling is desired, set
the temperature control to the MAX A/C
position, then set the fan speed control
to the highest setting.
NOTICE
When using the air conditioning system,
monitor the engine temperature gauge
closely while driving up hills or in heavy
traffic when outside temperatures are
high. Air conditioning system operation
when climbing a steep grade or in high
outside ambient temperatures can
cause engine overheating.
Continue to use the fan, but turn the air
conditioning system off if the engine
temperature gauge indicates engine
overheating.

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.
