OWNER MAINTENANCE
G030000AEN
The following lists are vehicle checks and
inspections that should be performed by
the owner or an authorized HYUNDAI
dealer at the frequencies indicated to
help ensure safe, dependable operation
of your vehicle.
Any adverse conditions should be
brought to the attention of your dealer as
soon as possible.
These Owner Maintenance Checks are
generally not covered by warranties and
you may be charged for labor, parts and
lubricants used.Owner maintenance schedule
G030101AUN
When you stop for fuel:
Check the engine oil level.
Check the coolant level in coolantreservoir.
Check the windshield washer fluid level.
Look for low or under-inflated tires.
WARNING- Maintenance work
Performing maintenance work on
a vehicle can be dangerous. You
can be seriously injured while
performing some maintenance
procedures. If you lack sufficient
knowledge and experience or the
proper tools and equipment to do
the work, have it done by an
authorized HYUNDAI dealer.
Working under the hood with the engine running is dangerous. It
becomes even more dangerous
when you wear jewelry or loose
clothing. These can become
entangled in moving parts and
result in injury. Therefore, if you
must run the engine while work-
ing under the hood, make certain
that you remove all jewelry (espe-
cially rings, bracelets, watches,
and necklaces) and all neckties,
scarves, and similar loose cloth-
ing before getting near the
engine or cooling fans.
WARNING
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot coolant
and steam may blow out under
pressure. This could cause burns
or other serious injury.

While operating your vehicle:
Note any changes in the sound of theexhaust or any smell of exhaust fumes
in the vehicle.
Check for vibrations in the steering wheel. Notice any increased steering
effort or looseness in the steering
wheel, or change in its straight-ahead
position.
Notice if your vehicle constantly turns slightly or “pulls” to one side when trav-
eling on smooth, level road.
When stopping, listen and check for unusual sounds, pulling to one side,
increased brake pedal travel or “hard-
to-push” brake pedal.
If any slipping or changes in the oper- ation of your transmission occurs,
check the transmission fluid level.
Check automatic transmission P (Park) function.
Check parking brake.
Check for fluid leaks under your vehicle (water dripping from the air condition-
ing system during or after use is nor-
mal).
G030103AUN
At least monthly:
Check the coolant level in the enginecoolant reservoir.
Check the operation of all exterior lights, including the stoplights, turn sig-
nals and hazard warning flashers.
Check the inflation pressures of all tires including the spare.
G030104AHM
At least twice a year (i.e., every Spring and Fall):
Check the radiator, heater and air con- ditioning hoses for leaks or damage.
Check the windshield washer spray and wiper operation. Clean the wiper
blades with clean cloth dampened with
washer fluid.
Check the headlight alignment.
Check the muffler, exhaust pipes, shields and clamps.
Check the lap/shoulder belts for wear and function.
Check for worn tires and loose wheel lug nuts.

EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
G050100AUN
Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in the
maintenance schedule. If the car is being
driven in severe conditions, more fre-
quent oil and filter changes are required.
G050200AUN
Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil satu-
ration and replace if necessary. Drive
belts should be checked periodically for
proper tension and adjusted as neces-
sary.
G050300ABH
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 exces-
sive amount of foreign matter accumu-
lates 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.
G050400ABH
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and con-
nections for leakage and damage. Have
an authorized HYUNDAI dealer replace
any damaged or leaking parts immedi-
ately.

G050600AUN
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
that a new vapor hose or fuel filler cap is
correctly replaced.
G050700AUN
Vacuum crankcase ventilation
hoses (if equipped)
Inspect the surface of hoses for evidence
of heat and/or mechanical damage. Hard
and brittle rubber, cracking, tears, cuts,
abrasions, and excessive swelling indi-
cate deterioration. 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 assure that
the hoses do not come in contact with
any heat source, sharp edges or moving
component which might cause heat dam-
age or mechanical wear. Inspect all hose
connections, such as clamps and cou-
plings, to make sure they are secure, and
that no leaks are present. Hoses should
be replaced immediately if there is any
evidence of deterioration or damage.
G050800AEN
Air cleaner filter
A Genuine HYUNDAI air cleaner filter is
recommended when the filter is
replaced.
G050900AUN
Spark plugs
Make sure to install new spark plugs of
the correct heat range.
G051000AEN
Valve clearance
Inspect excessive valve noise and/or
engine vibration and adjust if necessary.
An authorized HYUNDAI dealer should
perform the operation.
G051100AUN
Cooling system
Check cooling system components, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.
G051200AUN
Coolant
The coolant should be changed at the
intervals specified in the maintenance
schedule.
G051300ABK
Manual transmission fluid
(if equipped)
Inspect the manual transmission fluid
according to the maintenance schedule.
G051400ABK
Automatic transmission fluid
(if equipped)
Inspect the automatic transmission fluid
according to the maintenance schedule.
G051500AUN
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated or
damaged parts immediately.
