Convenient features of your vehicle
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.

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 win-
dows and sunroof closed.
Use the air conditioning system
every month for a few minutes to
ensure maximum system perform-
ance.
If you operate the air conditioner
excessively, the difference between
the temperature of the outside air
and that of the windscreen could
cause the outer surface of the wind-
screen to fog up, causing loss of vis-
ibility. In this case, set the mode
selection button to the position
and set the blower speed control
knob to the lowest speed setting.
System maintenance
Climate control air filter
This filter is installed behind the
glove box. It filters the dust or other
pollutants that enter the vehicle
through the heating and air condi-
tioning system.
We recommend that the climate con-
trol air filter be replaced by an autho-
rised HYUNDAI dealer according to
the maintenance schedule. If the
vehicle is being driven in severe con-
ditions such as dusty or rough roads,
more frequent climate control filter
inspections and changes are
required.If the air flow rate suddenly decreas-
es, we recommend the system be
checked at an authorised 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.

Driving your vehicle
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 fumes.
If at any time you smell engine exhaust fumes 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 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 blower speed control set to high so fresh air is drawn into the interior.
Keep the air intakes clear.
To ensure 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 blower speed control set to high.
WARNING

Driving your vehicle
The LKA system will not be in the
ENABLED state and the steering
wheel will not be assisted when:
The turn signal is turned on before
changing a lane. If you change
lanes without the turn signal on,
the steering wheel might be con-
trolled.
The vehicle is not driven in the mid-
dle of the lane when the system is
turned on or right after changing a
lane.
ESC (Electronic Stability Control)
is activated.
The vehicle is driven on a sharp
curve.
Vehicle speed is below 60 km/h or
over 180 km/h.
The vehicle makes sharp lane
changes.
The vehicle brakes suddenly.
Only one lane line is detected.
The lane is very wide or narrow.
There are more than two lane lines
on the road (e.g. construction area).
The vehicle is driven on a steep
incline.
Limitations of the System
The LKA system may operate pre-
maturely even if the vehicle does not
depart from the intended lane, OR,
the LKAS may not warn you if the
vehicle leaves the intended lane
under the following circumstances:
When the lane and road conditions
are poor
It is difficult to distinguish the lane
marking from the road surface or
the lane marking is faded or not
clearly marked.
There are markings on the road
surface that look like a lane line
that is inadvertently being detected
by the camera.
The lane line 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 lines
on the road in front of you.

The lanes 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 line in a tunnel is stained
with oil, etc.
When external condition is inter-
vened
The brightness outside changes
suddenly such as when entering or
exiting a tunnel or 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 in
the roadway such as a concrete
barrier, guardrail and reflector post
that is inadvertently being detected
by the camera.
When light coming from a street
light or an oncoming vehicle is
reflected on a wet road surface
such as a puddle on the road.
The field of view in front is
obstructed by sun glare.

Driving your vehicle
Use wire chains less than 12 mm
wide to prevent damage to the
chain’s connection.
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.
Check battery and cables
Winter temperatures affect battery
performance.Inspect the battery
and cables, as specified in the
chapter 7.The battery charging level
can be checked by an authorised
HYUNDAI dealer or in a service sta-
tion.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 chapter
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.

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 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 position.
Notice if your vehicle constantly turns
slightly or “pulls” to one side when
travelling 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 transmissiom
occurs, check the transmissiom 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). 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-pressure
pump, high-pressure pipes, rail,
and injectors are still subject to
high pressure immediately after
stopping the diesel engine.
When the fuel leakage vents out,
it may cause serious body injury.
Any people, who are implanted
with the artificial cardiac pace-
maker, 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 electronic engine control
system produce a considerable
amount of magnetic fields.

7,500km inspection, every 15,000km replacement". If there are some important safety matters like fuel flow restriction, surg-
ing, loss of power, hard starting problem etc., replace the fuel filter immediately regardless of maintenance schedule. We rec-
ommend that you consult an authorised HYUNDAI dealer for details.

Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in
the maintenance schedule. If the
vehicle is being driven in severe con-
ditions, more frequent oil and filter
changes are required.
Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Drive belts should be checked peri-
odically for proper tension and
adjusted as necessary.
Fuel filter (cartridge)
A clogged filter can limit the speed at
which the vehicle may be driven,
damage the emission system and
cause multiple issues such as hard
starting.
If an excessive amount of foreign
matter accumulates in the fuel tank,
the filter may require replacement
more frequently.
After installing a new filter, run the
engine for several minutes, and
check for leaks at the connections.
We recommend that the fuel filter be
replaced by an authorised HYUNDAI
dealer.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. We recommend that the fuel
lines, fuel hoses and connections be
replaced by an authorised HYUNDAI
dealer.
Vapour hose and fuel filler cap
The vapour hose and fuel filler cap
should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure that a new
vapour hose or fuel filler cap is cor-
rectly replaced.
Vacuum crankcase ventilation
hoses (if equipped)
Inspect the surface of hoses for evi-
dence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterio-
ration. Particular attention should be
paid to examine those hose surfaces
nearest to high heat sources, such
as the exhaust manifold.
Inspect the hose routing to ensure
that the hoses do not come in con-
tact with any heat source, sharp
edges or moving component which
might cause heat damage or
mechanical wear. Inspect all hose
connections, such as clamps and
couplings, to make sure they are
secure, and that no leaks are pres-
ent. Hoses should be replaced
immediately if there is any evidence
of deterioration or damage. When you are inspecting the belt,
place the ignition switch to the
LOCK/OFF or ACC position.
