Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning
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.
NOTICE
It is important that the correct type and
amount of oil and refrigerant are used.
Otherwise, damage to the compressor
and abnormal system operation may
occur. To prevent damage, the air
conditioning system in your vehicle
should only be serviced by trained and
certified technicians.
WARNING
Vehicles equipped with R-1234yf
Since the refrigerant is
mildly flammable and
operated at high pressure,
the air conditioning system
should only be serviced
by trained and certified
technicians. It is important
that the correct type
and amount of oil and
refrigerant are used.
All refrigerants should be reclaimed
with proper equipment.
Venting refrigerants directly to the
atmosphere is harmful to individuals
and environment. Failure to heed these
warnings can lead to serious injuries.

Information
OCN7050060
Your vehicle is filled with R-1234yf
according to the regulation in your
country at the time of production. You
can find out which air conditioning
refrigerant is applied to your vehicle on
the label located in front of the engine
compartment.
NOTICE
• 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 salvaged vehicle and new
replacement MAC evaporators shall
be certified (and labeled) as meeting
SAE Standard J2842.
Information
• When using the air conditioning
system, monitor the temperature
gauge closely while driving up hills
or in heavy traffic when outside
temperatures are high. Air conditioning
system operation may cause engine
overheating. Continue to use the blower
fan but turn the air conditioning system
off if the temperature gauge indicates
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 electrical equipment, air
conditioning should only be used with
the windows closed.

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 8. 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 8 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.
Use approved window washer anti-
freeze in system
To keep the water in the window washer
system from freezing, add an approved
window washer anti-freeze solution in
accordance with instructions on the
container. Window washer anti-freeze is
available from an authorized HYUNDAI
dealer and most auto parts outlets. Do
not use engine coolant or other types
of antifreeze as these may damage the
paint finish.
Do not let your parking brake freeze
Under some conditions your parking
brake can freeze in the engaged position.
This is most likely to happen when
there is an accumulation of snow or
ice around or near the rear brakes or
if the brakes are wet. If there is a risk
the parking brake may freeze, apply
it only temporarily while you put the
gear selector lever in P and block the
rear wheels so the car cannot roll. Then
release the parking brake.
Do not let ice and snow accumulate
underneath
Under some conditions, snow and ice
can build up under the fenders and
interfere with the steering. When driving
in severe winter conditions where this
may happen, you should periodically
check underneath the car to be sure the
movement of the front wheels and the
steering components is not obstructed.
Don't place foreign objects
or materials in the engine
compartment
Placement of foreign object or materials
which prevent cooling of the engine, in
the engine compartment, may cause a
failure or combustion. The manufacturer
is not responsible for the damage caused
by such placement.
To keep locks from freezing
To keep the locks from freezing, squirt
an approved de-icer fluid or glycerine
into the key opening. If a lock is covered
with ice, squirt it with an approved de-
icing fluid to remove the ice. If the lock
is frozen internally, you may be able to
thaw it out by using a heated key. Handle
the heated key with care to avoid injury.

Jump starting can be dangerous if done
incorrectly. Follow the jump starting
procedure in this section to avoid serious
injury or damage to your vehicle. If in
doubt about how to properly jump start
your vehicle, we strongly recommend
that you have a service technician or
towing service do it for you.
WARNING
To prevent SERIOUS INJURY or DEATH
to you or bystanders, always follow
these precautions when working near
or handling the battery:
Always read and follow
instructions carefully when
handling a battery.
Wear eye protection designed
to protect the eyes from acid
splashes.
Keep all flames, sparks, or
smoking materials away from
the battery.
Hydrogen is always present
in battery cells, is highly
combustible, and may explode
if ignited.
Keep batteries out of reach of
children.
Batteries contain sulfuric acid
which is highly corrosive. Do
not allow acid to contact your
eyes, skin or clothing.
If acid gets into your eyes, flush your
eyes with clean water for at least 15
minutes and get immediate medical
attention. If acid gets on your skin,
thoroughly wash the area. If you feel
pain or a burning sensation, get medical
attention immediately.
• When lifting a plastic-cased battery,
excessive pressure on the case may
cause battery acid to leak. Lift with a
battery carrier or with your hands on
opposite corners.
• Do not attempt to jump start your
vehicle if your battery is frozen.
• NEVER attempt to recharge the
battery when the vehicle’s battery
cables are connected to the battery.
• The electrical ignition system works
with high voltage. NEVER touch
these components with the engine
running or when the ignition switch
is in the ON position.
Information
An inappropriately disposed
battery can be harmful to
the environment and human
health. Dispose of the battery
according to your local law(s) or
regulations.
NOTICE
To prevent damage to your vehicle:
• Only use a 12-volt power supply
(battery or jumper system) to jump
start your vehicle.
• Do not attempt to jump start your
vehicle by push-starting.
