Convenient features of your vehicle
If the vehicle is being driven in
severe conditions such as dusty or
rough roads and/or if transporting
pets or occupants smoke inside the
vehicle, then more frequent cabin air
filter inspections 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 conditioner refrigerant andcompressor 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, have the system 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. The air conditioning system should
be serviced by an authorized
HYUNDAI dealer.
Air Conditioning refrigerant label
The actual Air Conditioning refriger-
ant label in the vehicle may differ
from the illustration.
Each symbols and specification on
air conditioning refrigerant label
means as below :
1. Classification of refrigerant
2. Amount of refrigerant
3. Classification of Compressor lubri-
cant
Refer to chapter 8 for more detail
location of the air conditioning refrig-
erant label.
NOTICE
ODH043366
■ Example
Because the refrigerant
is mildly inflammable at
very high pressure, the
air conditioning system
should only be serv-
iced by trained and cer-
tified technicians. It is
important that the cor-
rect type and amount of oil and
refrigerant is used. Otherwise, it
may cause damage to the vehi-
cle and personal injury.

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 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 lanemarker from the road because the
lane marker is covered with dust or
sand.
It is difficult to distinguish the color of the lane marker from the road.
There are markings on the road surface that look like a lane marker
that is inadvertently being detected
by the camera.
damaged.
The lane marker is merged or divided. (e.g. tollgate)
The lane number increases or decreases or the lane marker 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 marker ahead is not visible due to rain, snow, water on the
road, damaged or stained road sur-
face, 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 while
driving.
The surrounding of the inside rear view mirror temperature is high
due to direct sunlight, etc.

Driving your vehicle
When using tire chains:
Wrong size chains or improperly installed chains can damage
your vehicle's brake lines, sus-
pension, body and wheels.
Use SAE "S" class or wire chains.
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 type chain.
Use wire chains less than 0.47 in (12 mm) thick to prevent damage
to the chain's connection.
Winter Precautions
Use high quality ethylene glycolcoolant
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 ifnecessary
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.
