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 con-
ditions, more frequent oil and filterchanges 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 peri-
odically for proper tension and
adjusted as necessary.
Fuel lines, fuel hoses and con- nections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. We recommend that the fuel
lines, fuel hoses and connections be
replaced by an authorized HYUNDAI
dealer.
Fuel filter (for gasoline)
HYUNDAI gasoline vehicle is
equipped a lifetime fuel filter that
integrated with the fuel tank. Regularmaintenance or replacement is not
needed but depends on fuel quality. If
there are some important safety mat-
ters like fuel flow restriction, surging,
loss of power, hard starting problem
etc, fuel filter inspection or replace is
needed. We recommend that the fuel
filter be Inspected or replaced by an
authorized HYUNDAI dealer.
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure that a new
vapor hose or fuel filler cap is cor-rectly replaced.
Vacuum crankcase ventilation hoses (if equipped)
Inspect the surface of hoses for evi- dence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterio-
ration. Particular attention should be
paid to examine those hose surfaces
nearest to high heat sources, such
as the exhaust manifold.Inspect the hose routing to ensurethat the hoses do not come in con-
tact with any heat source, sharp
edges or moving component whichmight cause heat damage or
mechanical wear. Inspect all hose
connections, such as clamps and
couplings, to make sure they are
secure, and that no leaks are pres-
ent. Hoses should be replaced
immediately if there is any evidence
of deterioration or damage.
When you are inspecting the belt,
place the ignition switch to the
LOCK/OFF or ACC position.

2. Start the engine and allow it to reachnormal operating temperature.
3. Turn the engine off and wait for a few minutes (about 5 minutes) for
the oil to return to the oil pan.
4. Pull the dipstick out, wipe it clean, and re-insert it fully.
5. Pull the dipstick out again and check the level. The level should
be between F (Full) and L (Low).
6. If it is near or at L, add enough oil to bring the level to F. Do not overfill the engine oil.
It may damage the engine.
Do not spill engine oil, when adding or changing engine oil. If
you drop the engine oil on the
engine room, wipe it off immedi-
ately.
When you wipe the oil level gauge, you should wipe it with a clean
cloth. When mixed with debris, it
can cause engine damage.
Use only the specified engine oil.
(Refer to “Recommended lubricants
and capacities” in chapter 8.)NOTICE

Maintenance
Checking the engine oil and filter
We recommend that the engine oil
and filter be replaced by an author-
ized HYUNDAI dealer.The high-pressure cooling system
has a reservoir filled with year-round
antifreeze coolant. The reservoir is
filled at the factory.
Check the antifreeze protection and
coolant concentration level at least
once a year, at the beginning of the
winter season, and before traveling
to a colder climate.
When the engine overheats from
low engine coolant, suddenly
adding engine coolant may cause
cracks in the engine. To prevent
damage, add engine coolant
slowly in small quantities.
Do not drive with no engine coolant. It may cause water pump
failure and engine seizure, etc.
Checking the engine coolant
level
Check the condition and connections of all cooling system hoses and
heater hoses. Replace any swollen
or deteriorated hoses.
The coolant level should be filled
between MAX and MIN (or F (Full)
and L (Low)) marks on the side of the
coolant reservoir when the engine iscool.
NOTICE
Used engine oil may cause irri- tation or cancer of the skin if
left in contact with the skin for
prolonged periods of time. Used
engine oil contains chemicals
that have caused cancer in lab-
oratory animals. Always protect
your skin by washing your
hands thoroughly with soapand warm water as soon as pos-
sible after handling used oil.

Maintenance
If the coolant level is low, add enough
distilled (deionized) water. Bring the
level to MAX, (or F (Full)) but do not
overfill.
If frequent additions are required, werecommend that the system be
inspected by an authorized HYUNDAI
dealer.
The electric motor for the cooling fan
is controlled by engine coolant tem-
perature, refrigerant pressure and
vehicle speed. As the engine coolant
temperature decreases, the electric
motor will automatically shut off. This
is a normal condition. If your vehicle
is equipped with T-GDI, the electric
motor for the cooling fan may begin
to operate at any time and continue
to operate until you disconnect the
negative battery cable.
OOS077009
■Gasoline engine The electric motor for
the cooling fan may
continue to operate
or start up when theengine is not running
and can cause serious injury.
Keep hands, clothing and tools
away from the rotating fan bladesof the cooling fan.
WARNING
Never remove the
coolant cap/radiator cap or the drain plugwhile the engine and
radiator are hot. Hot
coolant and steam may blow out
under pressure, causing serious
injury.
Turn the engine off and wait until
the engine cools down. Use
extreme care when removing the
coolant cap/radiator cap. Wrap a
thick towel around it, and turn it
counterclockwise slowly to the
first stop. Step back while the
pressure is released from the
cooling system. When you aresure all the pressure has been
released, press down on the cap,
using a thick towel, and continue
turning counterclockwise to
remove it.

Maintenance
Recommended engine coolant
When adding coolant, use only dis-tilled (deionized) water for your
vehicle and never mix hard water in
the coolant filled at the factory. Anincorrect coolant mixture can result
in serious malfunction or engine
damage.
The engine in your vehicle has alu- minum engine parts and must be
protected by an ethylene-glycolwith phosphate based coolant to
prevent corrosion and freezing.
DO NOT USE alcohol or methanol coolant or mix them with the spec-ified coolant.
Do not use a solution that contains more than 60% antifreeze or less
than 35% antifreeze, which would
reduce the effectiveness of the solu-tion. For mixture percentage, refer to the
following table.
Information
If in doubt about the mix ratio, a 50%
water and 50% antifreeze mix is the
easiest to mix together as it will be the
same quantity of each. It is suitable to
use for most temperature ranges of
-35°C (-31°F) and higher.
Changing the engine coolant
We recommend that coolant be
changed by an authorized HYUNDAIdealer according to the MaintenanceSchedule at the beginning of this
chapter.
To prevent damage to engine parts,
put a thick towel around the radiator
cap and/or radiator cap before refill-
ing the coolant to prevent the
coolant from overflowing into
engine parts, such as the alternator.

Checking the brake/clutch
fluid level
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/clutch fluid, clean
the area around the reservoir cap
thoroughly to prevent brake/clutchfluid contamination.
If the level is low, add fluid to the MAX
level. The level will fall with accumulat-
ed 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 lubri-
cants and capacities” in chapter 8.
Information
Before removing the brake/clutch filler
cap, read the warning on the cap.
Information
Clean the filler cap before removing.
Use only DOT3 or DOT4 brake/clutch
fluid from a sealed container. Do not allow brake/clutch fluid
to contact the vehicle's body
paint, as paint damage willresult.
Brake/clutch fluid, which has been exposed to open air for an
extended time should never beused as its quality cannot be
guaranteed. It should be dis-
posed of properly.
Don't put in the wrong kind of fluid. A few drops of mineral-
based oil, such as engine oil, in
your brake/clutch system can
damage system parts.
NOTICE

Do not allow brake/clutch fluid
to come in contact with your
eyes. If brake/clutch fluid comes
in contact with your eyes, flush
your eyes with clean water for at
least 15 minutes and get imme-diate medical attention.
WARNING
If the brake/clutch system
requires frequent additions offluid this could indicate a leak in
the brake/clutch system. We
recommend that the vehicle be
inspected by an authorized
HYUNDAI dealer.
