Cabin air filter
OIK047401L[A] : Outside air, [B] : Recirculated air
[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.
We recommend that the cabin air filter
be 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,
we recommend the system 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, we
recommend that the system be 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.
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.

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.
• After sufficient cooling has been
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 windows
and sunroof closed.
• Use the air conditioning system every
month for a few minutes to ensure
maximum system performance.
• If you operate the air conditioner
excessively, the difference between
the temperature of the outside air and
that of the windshield could cause
the outer surface of the windshield to
fog up, causing loss of visibility. In this
case, set the mode selection button to
the
position and set the fan speed control knob to the lowest speed
setting.

ALL WHEEL DRIVE (AWD) (IF EQUIPPED)
„„Type A
ONX4060013
„„Type B
ONX4E060031
The All Wheel Drive (AWD) System
delivers engine power to all front and
rear wheels for maximum traction. AWD
is useful when extra traction is required
on roads such slippery, muddy, wet, or
snow-covered roads.
Occasional off-road use such as
established unpaved roads and trails are
OK. It is always important that the driver
carefully reduces the speed to a level
that does not exceed the safe operating
speed for those conditions.
WARNING
To reduce the risk of SERIOUS INJURY
or DEATH:
• Do not drive in conditions that
exceed the vehicles intended
design such as challenging off-road
conditions.
• Avoid high speeds when cornering or
turning.
• Do not make quick steering wheel
movements, such as sharp lane
changes or fast, sharp turns.
• The risk of a rollover is greatly
increased if you lose control of your
vehicle at highway speeds.
• Loss of control often occurs if two or
more wheels drop off the roadway
and the driver over steers to reenter
the roadway.
• In the event your vehicle leaves
the roadway, do not steer sharply.
Instead, slow down before pulling
back into the travel lanes.
NOTICE
• Do not drive in water if the level
is higher than the bottom of the
vehicle.
• Check your brake condition once
you are out of mud or water. Depress
the brake pedal several times as you
move slowly until you feel normal
braking return.
• Shorten your scheduled
maintenance interval if you drive in
off-road conditions such as sand,
mud or water (see "Maintenance
Under Severe Usage Conditions" in
chapter 7).
• Always wash your vehicle thoroughly
after off road use, especially the
bottom of the vehicle.
• Be sure to equip the vehicle with four
tires of the same size and type.
• Make sure that a full time AWD
vehicle is tow ed by a flat bed tow
truck.

Chain Installation
When installing tire chains, follow the
manufacturer’s instructions and mount
them as tightly possible. Drive slowly
(less than 20 mph (30 km/h)) with
chains installed. If you hear the chains
contacting the body or chassis, stop and
tighten them. If they still make contact,
slow down until the noise stops. Remove
the tire chains as soon as you begin
driving on cleared roads.
When mounting snow chains, park the
vehicle on level ground away from traffic.
Turn on the vehicle Hazard Warning
Flasher and place a triangular emergency
warning device behind the vehicle (if
available). Always place the vehicle in P
(Park), apply the parking brake and turn
off the engine before installing snow
chains.
NOTICE
When using tire chains:
• Wrong size chains or improperly
installed chains can damage your
vehicle’s brake lines, suspension,
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 vehicles
equipped with aluminum wheels. If
unavoidable, use a wire type chain.
• Use wire chains less than 0.47 in.
(12mm) thick 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 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.
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,
we recommend that you consult an
authorized HYUNDAI dealer.

Driving the vehicle after it has been
parked on a hill
1. With the gear in P (Park), apply your
brakes and hold the brake pedal down
while you:• Start your engine;
• Shift into gear; and
• Release the parking brake.
2. Slowly remove your foot from the
brake pedal.
3. Drive slowly until the trailer is clear of
the chocks.
4. Stop and have someone pick up and
store the chocks.
Maintenance when towing a
trailer
Your vehicle will need service more
often when you regularly pull a trailer.
Important items to pay particular
attention to include engine oil,
transmission fluid, axle lubricant and
cooling system fluid. Brake condition
is another important item to frequently
check. If you’re trailering, it’s a good
idea to review these items before
you start your trip. Don’t forget to
also maintain your trailer and hitch.
Follow the maintenance schedule that
accompanied your trailer and check it
periodically. Preferably, conduct the
check at the start of each day’s driving.
Most importantly, all hitch nuts and bolts
should be tight.
NOTICE
To prevent vehicle damage:
• Due to higher load during trailer
usage, overheating might occur on
hot days or during uphill driving.
If the coolant gauge indicates
over-heating, switch off the air
conditioner and stop the vehicle in a
safe area to cool down the engine.
• Do not switch off the engine while
the coolant gauge indicates over-
heating.
(Keep the engine idle to cool down
the engine)
• When towing check transmission
fluid more frequently.
• If your vehicle is not equipped with
an air conditioner, you should install
a condenser fan to improve engine
performance when towing a trailer.
