System Maintenance
Climate control air filter
OHI048581L
[A] : Outside air, [B] : Recirculated air
[C] : Climate control air filter, [D] : Blower
[E] : Evaporator core, [F] : PTC & Inner condenser
The cabin air filter is installed behind the
front trunk. 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
cabin air filter inspections and changes
are required.
If the air flow rate suddenly decreases,
have the system inspected at an
authorized HYUNDAI dealer.
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 conditixoning
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.

When All Wheel Drive(AWD) is
activated, driving forces are distributed
appropriately to front and rear wheels.
It could improve driving performance by
maximizing the driving force of vehicles
on severe road conditions such as steep
hills, unpaved, slippery, etc.
Advantage of electronic AWD
1. Improvement of straight stability
2. Improvement of driving performance
on curve
3. Secure stability on severe condition such as wet and sandy roads.
4. Improvement of energy efficiency
from driving mode automatic control.
Information
AWD vehicles could change the
engagement status of the motor according
to the situation required. Auto changing
the driving mode(2WD/AWD)helps
improve energy efficiency and driving
stability.
WARNING
To reduce the risk of SERIOUS INJURY
or DEATH: • 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"
section in chapter 9).
• 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 towed by a flat bed tow truck.

Owner Maintenance Schedule
When you stop for charging: • Check the coolant level in the coolant
reservoir.
• Check the windshield washer fluid
level.
• Check for low or under-inflated tires.
WARNING
Be careful when checking your coolant
level when the motor compartment is
hot. This may result in coolant being
blown out of the opening and cause
serious burns and other injuries.
While operating your vehicle: • Check for vibrations in the steering
wheel. Notice if there is any increased
steering effort or looseness in the
steering wheel, or change in its
straight-ahead position.
• Notice if your vehicle constantly turns
slightly or “pulls” to one side when
traveling 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 gear shift occurs,
check the shift gear fluid level.
• Check the shift gear 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 coolant
reservoir.
• Check the operation of all exterior
lights, including the stoplights, turn
signals and hazard warning flashers.
• Check the inflation pressures of all
tires including the spare for tires that
are worn, show uneven wear, or are damaged.
• Check for loose wheel lug nuts.
At least twice a year: (for example,
every Spring and Autumn) • Check radiator, heater and air
conditioning hoses for leaks or damage.
• Check windshield washer spray and
wiper operation. Clean wiper blades
with a clean cloth dampened with
washer fluid.
• Check headlamp alignment.
• Check the seat belts for wear and function.
At least once a year: • Clean body and door drain holes.
• Lubricate door hinges and hood hinges.
• Lubricate door and hood locks and
latches.
• Lubricate door rubber weather strips.
• Check the air conditioning system.
• Inspect and lubricate shift gear
linkage and controls.
• Clean the battery (12V) and terminals.
• Check the brake fluid level.
