If good quality gasolines or equivalents including fuel additives is not available, one bottle of additive is recommended.
Additives are available from your authorized HYUNDAI dealer along with information on how to use them. Do not mix other
additives.
à As it is normal for engine oil to be consumed during driving, the amount of engine oil should be checked regularly.

à The replacement cycle of engine oil is set by the period which the performance of our recommended engine oil is
maintained. So if recommended engine oil is not used, a replacement is required as indicated severe usage condition.

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.
Drive Belts
Inspect all drive belts for evidence
of cuts, cracks, excessive wear or oil
saturation and replace if necessary. Drive
belts should be checked periodically
for proper tension and adjusted as
necessary.
Fuel Filter
A clogged-up fuel filter may limit the
vehicle driving speed, damage the
emission system, and cause the hard
starting. When a considerable amount
of foreign substances are accumulated
in the fuel tank, the fuel filter should be
replaced.
Upon installing a new fuel filter, operate
the engine for several minutes, and
check the connections for any leakages.
Fuel filters should be installed by an
authorized HYUNDAI dealer.
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.
Have an authorized HYUNDAI dealer
replace any damaged or leaking parts
immediately.
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 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.
EXPLANATION OF SCHEDULED MAINTENANCE ITEMS

9-15
Engine Coolant/Inverter Coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
Dual Clutch Transmission Fluid
Dual clutch transmission fluid should
not be checked under normal usage
conditions.
We recommend that the Intelligent
variable transmission fluid is changed by
an authorized HYUNDAI dealer 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..
Brake Discs, Pads, Calipers and
Rotors
Check the pads for excessive wear, discs
for run out and wear, and calipers for
fluid leakage.
Suspension Mounting Bolts
Check the suspension connections for
looseness or damage. Retighten to the
specified torque.
Steering Gear Box, Linkage &
Boots/Lower Arm Ball Joint
With the vehicle stopped and the engine
off, check for excessive freeplay in the
steering wheel. Check the linkage for
bends or damage. Check the dust boots
and ball joints for deterioration, cracks,
or damage.
Replace any damaged parts.
Drive Shafts and Boots
Check the drive shafts, boots and clamps
for cracks, deterioration, or damage.
Replace any damaged parts and, if
necessary, repack the grease.
Air Conditioning Refrigerant
Check the air conditioning lines and
connections for leakage and damage.

Maintenance9-24
Checking the Brake/Clutch Fluid
Level
OCN7H090010
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX and MIN marks on the side
of the reservoir.
Before removing the reservoir cap and
adding brake fluid, clean the area around
the reservoir cap thoroughly to prevent
brake fluid contamination.
If the level is low, add fluid to the MAX
level. The level will fall with accumulated
mileage. This is a normal condition
associated with the wear of the brake
linings.
If the fluid level is excessively low, we
recommend that the system be checked
by an authorized HYUNDAI dealer.
Information
Use only the specified brake/clutch fluid.
Refer to “Recommended lubricants and
capacities” in chapter 2.
Information
Before removing the brake/clutch filler
cap, read the warning on the cap.
Information
Clean the filler cap before removing. Use
only DOT4 brake/clutch fluid from a
sealed container.
WARNING
Do not let brake fluid enter into your
eyes. If brake fluid gets in your eyes,
flush your eyes with clean water for
at least 15 minutes and get immediate
medical attention.
NOTICE

[ Do not allow brake/clutch fluid to
contact the vehicle’s body paint, as it
will result in paint damage.

[ NEVER use brake fluid which has
been exposed to open air for an
extended time, as its quality cannot
be guaranteed.

[ Don’t put in the wrong type of fluid.
A few drops of mineralbased oil such
as engine oil in your brake system
can damage system parts.

[ To maintain the best braking
performance and ABS/ESC
performance, we recommend that
you use genuine brake/clutch fluid
that conform to specifications.

3. Insert the air cleaner cover in the hinge (4) and engage the clip (5) after
closing the cover.
4. Check that the cover is firmly installed.
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. Use of
non-genuine parts could damage the
engine.
