2023 HYUNDAI I30 air filter

7-26
Maintenance
Air cleaner filter
We recommend that the air cleaner
filter be replaced by an authorised
HYUNDAI dealer.
Spark plugs
(for Petrol Engine)
Make sure to install new spark plugs
of the correct heat range.
Valve clearance
(for Petrol Engine)
Inspect excessive valve noise and/or
engine vibration and adjust if neces-
sary. We recommend that the system
be serviced by an authorised HYUNDAI
dealer.
Cooling system
Check the cooling system parts,
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 mainte-
nance schedule.
Automatic transmission fluid
(if equipped)
Automatic transmission fluid should
not be checked under normal usage
conditions.
We recommend that the automatic
transmission fluid is changed by an
authorised HYUNDAI dealer accord-
ing to the maintenance schedule.
Information
Automatic transmission fluid colour 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 colour
change.
The use of a non-specified fluid
could result in transmission mal-
function and failure.
Use only specified automatic
transmission fluid.
(Refer to “Recommended lubri-
cants and capacities” in chapter 8.)
Manual transmission fluid
(if equipped)
Inspect the manual transmission
fluid according to the maintenance
schedule.
NOTICE
i
Do not disconnect and inspect
spark plugs when the engine is
hot. You may burn yourself.

Draining water from fuel filter
The fuel filter in the diesel engine
operates the critical function of sepa-
rating water from the fuels and pre-
venting accumulating of water in the
base.
When enough water has accumulat-
ed inside the fuel filter, the warning
light ( ) illuminates with the igni-
tion switch in the ON position.
In this case, we recommend you to
have the system checked by an
authorised HYUNDAI dealer.
When the accumulated water is not
drained at the proper timing, water
may permeate in the fuel filter,
damaging the major vehicle com-
ponents, such as the fuel system.
Fuel filter cartridge replace-
ment
We recommend the fuel filter car-
tridge be replaced by an authorised
HYUNDAI dealer according to the
Maintenance Schedule at the begin-
ning of this chapter.
Filter replacement
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.NOTICE

Maintenance
1. Loosen the air cleaner cover
attaching clips and open the cover.
2. Wipe the inside of the air cleaner.
3. Replace the air cleaner filter.4. Lock the cover with the cover
attaching clips.
5. Check that the cover is firmly
installed.
Information
Be sure to insert the hinge (A) before
locking the cover with the cover
attaching clips.
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 chap-
ter).
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.
Use of non-genuine parts could
damage the air flow sensor.

Filter inspection
If the vehicle is operated in severely
air-polluted cities or on dusty rough
roads for a long period, it should be
inspected more frequently and
replaced earlier. When you, the
owner, replace the climate control air
filter, replace it performing the follow-
ing procedure, and be careful to
avoid damaging other components.
Replace the filter according to the
Maintenance Schedule.
Filter replacement
1. With the glove box open, remove
the stoppers on both sides.
2. Remove the support strap (1).3. Press and hold the lock (1) on both
sides of the cover.
4. Pull out the cover (2).

Maintenance
5. Replace the climate control air filter.
6. Reassemble in the reverse order
of disassembly.
Install a new climate control air filter
in the correct direction with the
arrow symbol (
↓ ↓) facing down-
wards, otherwise, it may be noisy
and the effectiveness of the filter
may be reduced.
Blade inspection
Contamination of either the wind-
screen or the wiper blades with for-
eign matter can reduce the effective-
ness of the windscreen wipers.
Common sources of contamination
are insects, tree sap, and hot wax
treatments used by some commer-
cial car washes. If the blades are not
wiping properly, clean both the win-
dow and the blades with a good
cleaner or mild detergent, and rinse
thoroughly with clean water.To prevent damage to the wiper
blades, arms or other compo-
nents, do not:
Use petrol, kerosene, paint thin-
ner, or other solvents on or near
them.
Attempt to move the wipers
manually.
Use non-specified wiper blades.
Information
Commercial hot waxes applied by
automatic car washes have been
known to make the windscreen diffi-
cult to clean.
Information
Wiper blades are a consumable item.
Normal wear of the wipers may not be
covered by your vehicle warranty.

The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty
information contained in the Service
Passport in your vehicle.
Your vehicle is equipped with an
emission control system to meet all
Australian Design Rules (ADR)
requirements.
There are three emission control
systems which are as follows.
(1) Crankcase emission control sys-
tem
(2) Evaporative emission control sys-
tem
(3) Exhaust emission control system
In order to ensure the proper function
of the emission control systems, it is
recommended that you have your
vehicle inspected and maintained by
an authorised HYUNDAI dealer in
accordance with the maintenance
schedule in this manual.For the Inspection and Maintenance
Test (with Electronic Stability
Control (ESC) system)
To prevent the vehicle from mis-
firing during dynamometer test-
ing, turn the Electronic Stability
Control (ESC) system off by
pressing the ESC switch.
After dynamometer testing is
completed, turn the ESC system
back on by pressing the ESC
switch again.1. Crankcase emission control
system
The positive crankcase ventilation
system is employed to prevent air
pollution caused by blow-by gases
being emitted from the crankcase.
This system supplies fresh filtered air
to the crankcase through the air
intake hose. Inside the crankcase,
the fresh air mixes with blow-by
gases, which then pass through the
PCV valve into the induction system.
2. Evaporative emission con-
trol system
The Evaporative Emission Control
System is designed to prevent fuel
vapours from escaping into the
atmosphere.

Diesel particulate filter (DPF)
(if equipped)
The Diesel Particulate Filter (DPF)
system removes the soot in the
exhaust gas.
The DPF system automatically burns
(or oxidises) the accumulated soot in
accordance with driving situations,
unlike a disposable air filter.
In other words, the accumulated soot
is automatically purged out by the
engine control system and by the high
exhaust-gas temperature at normal/
high driving speeds.
However, when the vehicle is continu-
ally driven at repeated short distances
or driven at low speed for a long time,
the accumulated soot may not be
automatically removed because of low
exhaust gas temperature. In this case,
the accumulated soot is out of the
detection range, the soot oxidisation
process does not occur, and the
Diesel Particulate Filter (DPF) Lamp
( ) Illuminates.The DPF Lamp stops illuminating,
when the driving speed exceeds 60
km/h, or when the engine rpm is
between 1,500 and 2,500 with the
gear in the 2nd position or above for
approximately 25 minutes.
When the DPF Lamp continuously
blinks or the warning message “Check
exhaust system” illuminates in the
above cases, we recommend that you
have the DPF system checked by an
authorised HYUNDAI dealer.
When the vehicle is continuously driv-
en with the DPF Lamp flashing for an
extended period of time, it may dam-
age the DPF system and lower the
fuel economy.Diesel Fuel
(if equipped with DPF)
We recommend you to use only
the regulated diesel fuels, when
your vehicle is equipped with
the DPF system.
When you use other diesel fuels,
which are high in sulfurs (above
50 ppm) or that contain unspeci-
fied additives, they may damage
the DPF system and cause white
smoke emissions.
