Climate control air filter
The climate control air filter installed
behind the glove box filters the dust
or other pollutants that come into the
vehicle from the outside through the
heating and air conditioning system.
If dust or other pollutants accumulate
in the filter over a period of time, the
air flow from the air vents may
decrease, resulting in moisture accu-
mulation on the inside of the wind-
screen even when the outside (fresh)
air position is selected. If this hap-
pens, we recommend that the cli-
mate control air filter be replaced by
an authorised HYUNDAI dealer.
Information
• Replace the filter according to the
Maintenance Schedule.
If the vehicle is being driven in
severe conditions such as dusty or
rough roads, more frequent climate
control air filter inspections and
changes are required.
• When the air flow rate suddenly
decreases, we recommend that the
system be checked by an authorised
HYUNDAI dealer.
Information
It is important that the correct type
and amount of oil and refrigerant is
used. Otherwise, damage to the com-
pressor and abnormal system opera-
tion may occur.

ant label in the vehicle may differ

an authorised HYUNDAI dealer.
Improper service may cause

Carbon monoxide (CO) gas is toxic. Breathing CO can cause unconsciousness and death.
Engine exhaust emissions contain carbon monoxide which cannot be seen or smelled.
Do not inhale engine exhaust.
If at any time you smell engine exhaust emissions 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, we recommend that the exhaust system be checked as soon as possible by an authorised 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 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 windscreen
clear of snow, ice, leaves, or other obstructions.
If you must drive with the tailgate 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.
WARNING

The steering will not be assisted
when the lane is very wide or nar-
row.
There are more than two lane
markers such as in a construction
area.
The vehicle is driven on a steep
incline.
The steering wheel is turned sud-
denly.
Limitations of the System
The LKA system may operate pre-
maturely even if the vehicle does not
depart from the intended lane, OR,
the LKA system may not assist your
steering or warn you if the vehicle
leaves the intended lane under the
following circumstances:
When the lane and road condi-
tions are poor
It is difficult to distinguish the lane
marker from the road surface or
the lane marker is faded or not
clearly marked. It is difficult to distinguish the
colour of the lane marker from the
road.
There are markings on the road
surface that look like a lane marker
that are inadvertently being detect-
ed by the camera.
The lane marker is indistinct or
damaged.
The lane marker is merged or
divided. (e.g. tollgate)
The lane number increases or
decreases or the lane markers are
crossing complicatedly.
There are more than two lane
markers on the road in front of you.
The lane marker is very thick or
thin.
The lane is very wide or narrow.
The lane markers ahead are not
visible due to rain, snow, water on
the road, damaged or stained road
surface, or other factors. A shadow is on the lane marker by
a median strip, trees, etc.
The lanes are incomplete or the
area is in a construction zone.
There are crosswalk signs or other
symbols on the road.
The lane marker in a tunnel is
stained with oil, etc.
The lane suddenly disappears
such as at an intersection.
When external conditions are
intervene
The brightness outside changes
suddenly such as when entering or
exiting a tunnel, or when passing
under a bridge.
The brightness outside is too low
such as when the headlamps are
not on at night or the vehicle is
going through a tunnel.
There is a boundary structure on
the roadway such as a concrete
barrier, guardrail and reflector post
that is inadvertently being detected
by the camera.

Check battery and cables
The winter temperature increases
the battery consumption.Inspect
the battery and cables, as speci-
fied in chapter 7.The battery charg-
ing level can be checked by an
authorised HYUNDAI dealer or in a
service station.
Change to "winter weight" oil if
necessary
In some regions during winter, it is
recommended to use the "winter
weight" oil with lower viscosity. For
further information, refer to the chap-
ter 8. When you are not sure about a
type of winter weight oil, consult an
authorised HYUNDAI dealer.Check spark plugs and ignition
system
Inspect the spark plugs, as speci-
fied in chapter 7.If necessary,
replace them. Also check all ignition
wirings and components for any
cracks, wear-out, and damage.
To prevent locks from freezing
To prevent the locks from being
frozen, spray approved de-icing fluid
or glycerin into key holes. When a
lock opening is already covered with
ice, spray approved de-icing fluid
over the ice to remove it. When an
internal part of a lock freezes, try to
thaw it with a heated key. Carefully
use the heated key to avoid an injury.Use approved window washer
anti-freeze solution in system
To prevent the window washer from
being frozen, add authorised window
washer anti-freeze solution, as spec-
ified on the window washer contain-
er. Window washer anti-freeze solu-
tion is available from an authorised
HYUNDAI dealer, and so are the
most vehicle accessory outlets. Do
not use engine coolant or other types
of anti-freeze solution to prevent any
damage to the vehicle paint.

Maintenance
Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check coolant level in the engine
coolant reservoir.
Check the windscreen washer fluid
level.
Check for low or under-inflated
tyres.
Whilst 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 travelling on a smooth, level
road.
When stopping, listen and check
for unusual sounds, pulling to one
side, increased brake pedal travel
or a “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 transmis-
sion/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). 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.
WARNING
Diesel Engine
Never manipulate or modify the
injection system whilst running
the diesel engine or within 30
seconds after turning OFF the
diesel engine. The high-pres-
sure pump, high-pressure
pipes, rail, and injectors are still
subject to the high pressure
right after stopping the diesel
engine. When the fuel leakage
vents out, it may cause serious
body injury. Any people, who
are implemented with the artifi-
cial cardiac pacemaker, should
remain away from the ECU or
the wiring harness by at least 30
cm, whilst running the diesel
engine. The high currents of the
electric engine control system
produce a considerable amount
of magnetic fields.
