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.
Have 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,
have the system be checked 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 conditioning system.
Therefore, if abnormal operation is found,
have 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.

Air cleaner filter
Have the air cleaner filter be replaced by
an authorized HYUNDAI dealer.
Spark plugs
Make sure to install new spark plugs of
the correct heat range.
When assembling parts, be sure to
wipe out foreign substances inside
and outside of the boot bottom of the
ignition coil and the insulator of the
spark plug with a soft cloth to prevent
contamination of the spark plug
insulator.
Cooling system
Check cooling system components, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.
Engine coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
Engine coolant/water-cooled
intercooler coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
Automatic transmission fluid
Automatic transmission fluid should
not be checked under normal usage
conditions.
Have the automatic transmission fluid
be changed by an authorized HYUNDAI
dealer according to the maintenance
schedule.
Information
Automatic transmission fluid color is red
when new.
As the vehicle is driven, the automatic
transmission fluid will begin to look
darker.
This is a normal condition. It does not
need to be replaced based on the color
change.
NOTICE
The use of a non-specified fluid could
result in transmission malfunction and
failure.
Use only specified automatic
transmission fluid. (Refer to
“Recommended Lubricants and
Capacities” section in chapter 2.)
Dual clutch transmission fluid (if
equipped)
Inspect the dual clutch transmission fluid
according to the maintenance schedule.
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated or
damaged parts immediately.
Brake fluid
Check the brake fluid level in the brake
fluid reservoir. The level should be
between the MIN and the MAX marks
on the side of the reservoir. Use only
hydraulic brake fluid conforming to DOT
4 specification.
Parking brake
Inspect the parking brake system
including the parking brake lever and
cables.

Maintenance9-24
Filter replacement
OTMA090007
The air cleaner filter can be cleaned for
inspection using compressed air. Do not
attempt to wash or to rinse it, as water
will damage the filter. If soiled, the air
cleaner filter must be replaced.
OTMA090008
1. Pull up the air cleaner filter cover (1).
OTMA090023
2. Wipe the inside of the air cleaner.
3. Pull down the lever to the UNLOCK (2) position.
OTMA090024
4. Replace the air cleaner filter.
5. Reassemble the air cleaner cover in the reverse order.
Information
If the vehicle is operated in extremely
dusty or sandy areas, replace the element
more often than the usual recommended
intervals (refer to “Maintenance Under
Severe Usage Conditions” in this chapter).
NOTICE

[Do not drive with the air cleaner filter
removed. This will result in excessive
engine wear.

[ When removing the air cleaner filter,
be careful that dust or dirt does not
enter the air intake, or damage may
result.

[ Use HYUNDAI genuine parts or the
equivalent specified for your vehicle.
Use of non-genuine parts could
damage the air flow sensor.
