System Maintenance
Cabin air filter

[C] : Cabin air filter, [D] : Blower
[E] : Evaporator core, [F] : Heater core
The cabin air filter is installed behind
the glove box. It filters the dust or other
pollutants that enter the vehicle through
the heating and air conditioning system.
Have the cabin air filter replaced by an
authorized HYUNDAI dealer according to
the maintenance schedule. If the vehicle
is being driven in severe conditions such
as dusty or rough roads, more frequent
climate control filter inspections and
changes are required.
If the air flow rate suddenly decreases,
the system should be checked at an
authorized HYUNDAI dealer.
Air Conditioning Performance and
Maintenance at Your HYUNDAI
Dealer
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 is 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.
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.

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.

Driving in Flooded Areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel hub.
Drive through any water slowly. Allow
adequate stopping distance because
brake performance may be reduced.
After driving through water, dry the
brakes by gently applying them several
times while the vehicle is moving slowly.
Highway Driving
Tires
Adjust the tire inflation, as specified.
Under-inflation may overheat or damage
the tires.
Do not install worn-out or damaged tires,
which may reduce traction or fail the
braking operation.
Information
Never over-inflate your tires above the
maximum inflation pressure, as specified
on your tires.
Fuel, engine coolant and engine oil
Driving at higher speeds on the highway
consumes more fuel and is less efficient
than driving at a slower, more moderate
speed. Maintain a moderate speed in
order to conserve fuel when driving on
the highway.
Be sure to check both the engine coolant
level and the engine oil before driving.
Drive belt
A loose or damaged drive belt may
overheat the engine.
Reducing the Risk of a Rollover
Your multi-purpose passenger vehicle is
defined as a Sports Utility Vehicle (SUV).
SUV’s have higher ground clearance
and a narrower track to make them
capable of performing in a wide variety
of off-road applications. The specific
design characteristics give them a higher
center of gravity than ordinary vehicles
making them more likely to roll over if
you make abrupt turns. Utility vehicles
have a significantly higher rollover rate
than other types of vehicles. Due to this
risk, driver and passengers are strongly
recommended to buckle their seat belts.
In a rollover crash, an unbelted person
is significantly more likely to die than a
person wearing a seat belt.
There are steps that a driver can make
to reduce the risk of a rollover. If at all
possible, avoid sharp turns or abrupt
maneuvers, do not load your vehicle
with heavy cargo on the roof, and never
modify your vehicle in any way.
WARNING
Utility vehicles have a significantly
higher rollover rate than other types of
vehicles. To prevent rollovers or loss of
control:

[Take corners at slower speeds than
you would with a passenger vehicle.

[ Avoid sharp turns and abrupt
maneuvers.

[ Do not modify your vehicle in any
way that you would raise the center
of gravity.

[ Keep tires properly inflated.

[ Do not carry heavy cargo on the roof.
WARNING
In a rollover crash, an unbelted person
is significantly more likely to die than a
person wearing a seat belt. Make sure
all passengers are wearing their seat
belts.

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 cooling
system, lubricates the water pump and
prevents freezing. Be sure to replace or
replenish your coolant in accordance
with the maintenance schedule in
chapter 9. 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 chapter 9. The
battery charging level can be checked
by an authorized HYUNDAI dealer or in a
service station.
If the vehicle is not used for a long time,
park the vehicle indoors if possible.
Change to “winter weight” oil if
necessary
In some regions during winter, it is
recommended to use the “winter
weight” oil with lower viscosity In
addition, replace the engine oil and filter
if it is close to the next maintenance
interval. Fresh engine oil ensures
optimum engine operation during the
winter months. For further information,
refer to chapter 2. When you are not sure
about a type of winter weight oil, consult
an authorized HYUNDAI dealer.Check spark plugs and ignition system
Inspect the spark plugs, as specified in
chapter 9. 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 authorized window
washer anti-freeze solution, as specified
on the window washer container.
Window washer anti-freeze solution is
available from an authorized 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.

WASHER FLUID
Checking the Washer Fluid Level
ONX4H090010ONX4H090010
Check the fluid level in the washer fluid
reservoir and add fluid if necessary.
Plain water may be used during summer
months if washer fluid is not available.
However, use washer solvent with
antifreeze characteristics in cold climates
to prevent freezing.
WARNING
To prevent serious injury or death, take
the following safety precautions when
using washer fluid:
• Do not use engine coolant or
antifreeze in the washer fluid
reservoir. Engine coolant can
severely obscure visibility when
sprayed on the windshield and
may cause loss of vehicle control
resulting in an accident or damage to
paint and body trim.
• Do not allow sparks or flame to
contact the washer fluid or the
washer fluid reservoir. Washer fluid
may contain alcohol and can be
flammable.
• Do not drink washer fluid and avoid
contact with skin. Washer fluid is
harmful to humans and animals.
• Keep washer fluid away from
children and animals.
WARNING
Do not let brake fluid enter into your
eyes. If brake fluid gets in your eyes,
flush your eyes with clean water for
at least 15 minutes and get immediate
medical attention.
NOTICE
• Do not allow brake fluid to contact
the vehicle’s body paint, as it will
result in paint damage.
• NEVER use brake fluid which has
been exposed to open air for an
extended time, as its quality cannot
be guaranteed.
• Do not use the wrong type of brake
fluid. A few drops of mineral based
oil, such as engine oil in your brake
system can damage brake system
parts.
Information
Use only the specified brake fluid (refer
to “Recommended Lubricants and
Capacities” section in chapter 2).
