Convenient features of your vehicle
The refrigerant system should
only be serviced by trained and
certified technicians to insure
proper and safe operation.
The refrigerant system should
be serviced in a well-ventilated
place.
The air conditioning evaporator
(cooling coil) shall never be
repaired or replaced with one
removed from a used or sal-
vaged vehicle and new replace-
ment MAC evaporators shall be
certified (and labelled) as meet-
ing SAE Standard J2842.
Information
• When using the air conditioning sys-
tem, monitor the temperature gauge
closely whilst driving up hills or in
heavy traffic when outside tempera-
tures are high. Air conditioning sys-
tem operation may cause engine
overheating. Continue to use the fan
but turn the air conditioning system
off if the temperature gauge indi-
cates engine overheating.
• When opening the windows in
humid weather, air conditioning
may create water droplets inside the
vehicle. Since excessive water
droplets may cause damage to elec-
trical equipment, air conditioning
should only be used with the win-
dows closed.
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.
Use air conditioning to reduce
humidity and moisture inside the
vehicle on rainy or humid days.
During air conditioning system
operation, you may occasionally
notice a slight change in engine
speed as the air conditioning com-
pressor cycles. This is a normal
system operation characteristic.
Use the air conditioning system
every month only for a few minutes
to ensure maximum system per-
formance.
When using the air conditioning
system, you may notice clear water
dripping (or even puddling) on the
ground under the passenger side
of the vehicle. This is a normal sys-
tem operation characteristic.

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, 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 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.

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 marker ahead is not visi-
ble due to rain, snow, water on the
road, damaged or stained road
surface, or other factors.
The shadow is on the lane marker
by a median strip, trees, guardrail,
noise barriers, etc.
The lane markers are complicated
or a structure substitutes for the
lines such as a construction area.
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 the intersection.When external condition is inter-
vened
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 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 in the road.
The field of view in front is
obstructed by sun glare.
There is not enough distance
between you and the vehicle in
front to be able to detect the lane
marker or the vehicle ahead is driv-
ing on the lane marker. Driving on a steep grade, over a
hill, or when driving on a curved
road.
The adverse road conditions cause
excessive vehicle vibrations whilst
driving.
The surrounding of the inside rear
view mirror temperature is high
due to direct sunlight, etc.
When front visibility is poor
The windscreen or the camera lens
is blocked with dirt or debris.
The windscreen glass is fogged
up; a clear view of the road is
obstructed.
Placing objects on the dashboard,
etc.
The sensor cannot detect the lane
because of fog, heavy rain or snow.

Driving your vehicle
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 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 the 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 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 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 posi-
tion.
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 transmission
occurs, check the transmission
fluid level.
Check the 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 stoplights, turn
signals and hazard warning flashers.
Check the inflation pressures of all
tyres including the spare for tyres
that are worn, show uneven wear,
or are damaged.
Check for loose wheel lug nuts.
At least twice a year:
(i.e., every Spring and Autumn)
Check radiator, heater and air condi-
tioning hoses for leaks or damage.
Check windscreen washer spray
and wiper operation. Clean wiper
blades with a clean cloth damp-
ened with washer fluid.
Check headlamp alignment.
Check muffler, exhaust pipes,
shields and clamps.
Check the seat belts for wear and
function. Be careful when checking your
engine coolant/inverter 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.

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.
HSG (Hybrid starter & genera-
tor) belt
The HSG belt should be changed at
the intervals specified in the mainte-
nance schedule.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. We recommend an authorised
HYUNDAI dealer replace any dam-
aged or leaking parts immediately.
Fuel filter
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. Fuel filters
should be installed 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 a new vapour
hose or fuel filler cap is correctly
replaced.
Air cleaner filter
A genuine HYUNDAI air cleaner filter
is recommended when the filter is
replaced.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.
Cooling system
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Engine coolant/inverter
coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
