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.

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 liftgate 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.

Limitation of SMART mode 
The SMART mode may be limited in
following situations. (The OFF indica-
tor illuminates in those situations.) 
 The driver manually moves the
shift lever :
It deactivates SMART mode. The
vehicle drives, as the driver manu-
ally moves the shift lever.
 The cruise control is activated :
The cruise control system may
deactivate the SMART mode when
the vehicle is controlled by the set
speed of the smart cruise control
system. (SMART mode is not
deactivated just by activating the

either extremely low or extremely
high :
The SMART mode can be active in
most of the normal driving situa-
tions. However, an extremely high/
low transmission oil temperature
may temporarily deactivate the
SMART mode, because the trans-
mission condition is out of normal
operation condition.
SPORT MODE 
(with Manual Transmission)
The drive mode may be selected
according to the driver's preference
or road condition.
Information 
If there is a problem with the instru-
ment cluster, the drive mode will be in

- 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.

Maintenance
Owner Maintenance Schedule
When you stop for fuel:
• Check the engine oil level.
 Check the coolant level in the
engine coolant reservoir.
 Check the windshield washer fluid
level.
 Check the for low or under-inflated
tires.
While operating your vehicle:
 Note any changes in the sound of
the exhaust or any smell of
exhaust fumes in the vehicle.
 Check for vibrations in the steering
wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead posi-
tion.
 Notice if your vehicle constantly
turns slightly or "pulls" to one side
when traveling on smooth, level
road.
 When stopping, listen and check
for unusual sounds, pulling to one
side, increased brake pedal travel
or "hard-to-push" brake pedal.
 If any slipping or changes in the
operation of your transmission
occurs, check the transmission
fluid level.
 Check the automatic transmission/
dual clutch transmission P (Park)
function. Check the parking brake.
 Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
 Check coolant level in the engine
coolant reservoir.
 Check the operation of all exterior
lights, including the brake lights,
turn signals and hazard warning
flashers.
 Check the inflation pressures of all
tires including the spare for tires
that are worn, show uneven wear,
or are damaged.
 Check for loose wheel lug nuts. Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious
burns and other injuries.
