Operation Tips
To keep dust or unpleasant fumes
from entering the vehicle through
the ventilation system, temporarily
set the air intake control to recircu-
lation mode. Return the control to
Fresh mode when the unpleasant
air outside has diminished. This will
help keep the driver alert and com-
fortable.
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 condition-
ing 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.When using the air conditioning
system, monitor the engine tem-
perature gauge closely while driv-
ing 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 tempera-
tures can cause engine overheat-
ing.
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
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 con-
ditioning system with the windows
and sunroof closed.
Use the air conditioning system
every month only for a few minutes
to ensure maximum system per-
formance.
If you operate air conditioner exces-
sively, 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
[A] : Outside air, [B] : Recirculated air
[C] : Climate control 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 condition-
ing system.
Have the cabin air filter replaced by an
authorized HYUNDAI dealer accord-
ing to the maintenance schedule. If the
vehicle is being driven in severe con-
ditions such as dusty or rough roads,
more frequent cabin air filter inspec-
tions and changes are required.If the air flow rate suddenly decreas-
es, the system should be checked at
an authorized HYUNDAI dealer.
Checking the amount of air con-
ditioner refrigerant and com-
pressor lubricant
When the amount of refrigerant is
low, the performance of the air con-
ditioning is reduced. Overfilling also
reduces the performance of the air
conditioning system.
Therefore, if abnormal operation is
found, we recommend that the sys-
tem be inspected by an authorized
HYUNDAI dealer.
It is important that the correct
type and amount of oil and refrig-
erant is used. Otherwise, damage
to the compressor and abnormal
system operation may occur. To
prevent damage, the air condition-
ing system in your vehicle should
only be serviced by trained and
certified technicians.

Driving your vehicle
- When using tire chains:
Make sure to use the right size
and type of snow chains for your
tires. Incorrect snow chains can
cause damage to the vehicle
body and suspension. Damage
to your vehicle caused by
improper tire chain use is not
covered by your vehicle manu-
facturer's warranty.
If you hear noise caused by
chains contacting the body,
retighten the chain to prevent
contact with the vehicle body.
To prevent body damage,
retighten the chains after driving
0.3~0.6 miles (0.5~1.0 km).
Do not use tire chains on vehi-
cles equipped with aluminum
wheels. If unavoidable, use a
wire or fabric type snow chain.
When using tire chains, install
the right type chain according to
the below tire sizes.
- 215/45R17 : Wire type chain
- 225/40R18 : Fabric type chain
(Autosock) Use wire chains less than 0.47
inch (12 mm) wide to prevent
damage to the chain's connec-
tion.
Winter Precautions
Use high quality ethylene glycol
coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because
it helps prevent corrosion in the cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in chapter 7. Before winter,
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.
Change to "winter weight" oil if
necessary
In some climates it is recommended
that a lower viscosity "winter weight"
oil be used during cold weather. See
chapter 8 for recommendations. If
you aren't sure what weight oil you
should use, consult an authorized
HYUNDAI dealer.
Check battery and cables
Winter puts additional burdens on
the battery system. Visually inspect
the battery and cables as described
in chapter 7. The level of charge in
your battery can be checked by an
authorized HYUNDAI dealer or a
service station.
Check spark plugs and ignition
system
Inspect your spark plugs as
described in chapter 7 and replace
them if necessary. Also check all
ignition wiring and components to be
sure they are not cracked, worn or
damaged in any way.
