Maintenance9-14
Engine Oil and Filter
The engine oil and filter should be
changed at the intervals specified in the
maintenance schedule. If the vehicle
is being driven in severe conditions,
more frequent oil and filter changes are
required.
HSG (Hybrid Starter & Generator)
Belt
The HSG belt should be changed at the
intervals specified in the maintenance
schedule.
Fuel Lines, Fuel Hoses and
Connections
Check the fuel lines, fuel hoses and
connections for leakage and damage.
We recommend an authorized HYUNDAI
dealer replace any damaged or leaking
parts immediately.
Fuel Filter
A clogged filter can limit the speed
at which the vehicle may be driven,
damage the emission system and cause
multiple issues such as hard starting. If
an excessive amount of foreign matter
accumulates in the fuel tank, the
filter may require replacement more
frequently. After installing a new filter,
run the engine for several minutes,
and check for leaks at the connections.
Fuel filters should be installed by an
authorized HYUNDAI dealer.
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should
be inspected at those intervals specified
in the maintenance schedule. Make sure
a new vapor hose or fuel filler cap is
correctly replaced.
Air Cleaner Filter
A genuine HYUNDAI air cleaner filter
is recommended when the filter is
replaced.
Spark Plugs
Make sure to install new spark plugs of
the correct heat range.
When assembling parts, be sure to
wipe the 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/Inverter 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.
We recommend that the automatic
transmission fluid is changed by an
authorized HYUNDAI dealer according to
the maintenance schedule.
Engine Clutch Actuator Fluid
The engine clutch actuator fluid level
should be inspected or replaced to the
intervals specified in the maintenance
schedule.
EXPLANATION OF SCHEDULED MAINTENANCE ITEMS

9-17
Checking the Engine Oil and
Filter

[The lubrication, rust prevention,
cooling, and cleaning effect of the
engine oil will gradually degrade
during its use. Have the engine oil and
filter be changed by an authorized
HYUNDAI dealer according to the
Oil Life Management System or
the Maintenance Schedule at the
beginning of this chapter.

[ If the maintenance schedule to
replace engine oil is exceeded,
the engine oil performance may
deteriorate, and the engine condition
may be affected. Therefore, replace
the engine oil according to the
maintenance schedule.

[ To keep the engine in optimal
condition, use the recommended
engine oil and filter. If the
recommended engine oil and filter are
not used, replace it according to the
maintenance schedule under severe
usage conditions.

[ The purpose of the maintenance
schedule for engine oil replacement
is to prevent oil deterioration and it is
irrelevant to oil consumption. Check
and refill engine oil regularly.
Information
When the oil pressure is low due to
insufficient engine oil, the Engine
Oil Pressure (
) warning light will
illuminate. In addition, the enhanced
engine protection system, which limits
the engine’s power is activated and the
Malfunction Indicator Lamp (
) will
illuminate when the vehicle is driven in
this state continuously. When oil pressure
is restored, the Engine Oil Pressure
warning light will turn off and the engine
power will no longer be limited.
CAUTION
The engine oil is very hot immediately
after the vehicle has been driven and
can cause burns during replacement.
Replace the engine oil after the engine
oil has cooled down.
WARNING
CALIFORNIA PROPOSITION 65
WARNING
Engine oil contains chemicals known to
the State of California to cause cancer,
birth defects and reproductive harm.
Used engine oil may cause irritation or
cancer of the skin if left in contact with
the skin for prolonged periods of time.
Always protect your skin by washing
your hands thoroughly with soap and
warm water as soon as possible after
handling used oil.

Maintenance9-24
Filter Replacement
OTMH090012
Do not attempt to wash or to rinse it, as
water will damage the filter.
If soiled, the air cleaner filter must be
replaced.
Replace the filter according to the
Maintenance Schedule.
OTMH090013
1. Loosen the air cleaner cover attaching clips and open the cover.
OTMH090023
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
If the vehicle is operated in extremely
dusty or sandy areas, replace the air
cleaner filter more often than the
usual recommended intervals (Refer
to “Maintenance Under Severe Usage
Conditions” section 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 speficied for your vehicle.
Use of parts without the matching
