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 forproper 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.

Maintenance
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 iscorrectly 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 movingcomponent 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 isreplaced.
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.

G051600AUN Brake fluid
Check brake fluid level in the brake fluid
reservoir. The level should be between
“MIN” and “MAX” marks on the side of
the reservoir. Use only hydraulic brake
fluid conforming to DOT 3 or DOT 4specification.
G051700AUN
Parking brake
Inspect the parking brake system includ-
ing the parking brake pedal and cables.
G051900AUN
Brake discs, pads, calipers and
rotors
Check the pads for excessive wear, discs
for run out and wear, and calipers for fluid
leakage.
G052100AUN Suspension mounting bolts
Check the suspension connections for
looseness or damage. Retighten to the
specified torque. G052200AUN
Steering gear box, linkage &
boots/lower arm ball joint
With the vehicle stopped and engine off,
check for excessive free-play 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. G052300AEN
Power steering pump, belt and hoses
Check the power steering pump and
hoses for leakage and damage. Replace
any damaged or leaking parts immedi-
ately. Inspect the power steering belt (or
drive belt) for evidence of cuts, cracks,
excessive wear, oiliness and proper ten-
sion. Replace or adjust it if necessary.
G052400AUN Drive shafts and boots
Check the drive shafts, boots and clamps
for cracks, deterioration, or damage.
Replace any damaged parts and, if nec-
essary, repack the grease.
G052500AUN
Air conditioning refrigerant (if equipped)
Check the air conditioning lines and con-
nections for leakage and damage.

ENGINE OIL
G060100AEN
Checking the engine oil level
1. Be sure the vehicle is on level ground.
2. Start the engine and allow it to reach normal 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 betweenF and L.
If it is near or at L, add enough oil to bring
the level to F.Do not overfill.
Use a funnel to help prevent oil frombeing spilled on engine components.
Use only the specified engine oil. (Refer to “Recommended lubricants and capaci- ties” in section 8.)
WARNING - Radiator hose
Be very careful not to touch the
radiator hose when checking or
adding the engine oil as it may be
hot enough to burn you.

G060200AEN Changing the engine oil and filter
Have engine oil and filter changed by an
authorized HYUNDAI dealer according tothe Maintenance Schedule at the begin-ning of this section. G070000AUN The high-pressure cooling system has a
reservoir filled with year-round antifreeze
coolant. The reservoir is filled at the fac-
tory.
Check the antifreeze protection and
coolant level at least once a year, at thebeginning of the winter season, and
before traveling to a colder climate. G070100AEN
Checking the coolant level
WARNING
Used engine oil may cause irrita- tion 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 laboratory ani-
mals. Always protect your skin by
washing your hands thoroughlywith soap and warm water as soon
as possible after handling used oil.
ENGINE COOLANT
WARNING - Removing
radiator cap
Never attempt to remove the radi- ator cap while the engine is oper-
ating or hot. Doing so might leadto cooling system and engine
damage and could result in seri-
ous personal injury from escap-ing hot coolant or steam.
(Continued)
(Continued)
Turn the engine off and wait untilit cools down. Use extreme care
when removing the 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.
Even if the engine is not operat- ing, do not remove the radiatorcap or the drain plug while the
engine and radiator are hot. Hot
coolant and steam may still blow
out under pressure, causing seri-
ous injury.

719
Maintenance
Check the condition and connections of all cooling system hoses and heater
hoses. Replace any swollen or deterio-
rated hoses.
The coolant level should be filled
between F and L marks on the side of the
coolant reservoir when the engine iscool.If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the
level to F, but do not overfill. If frequent
additions are required, see an authorized
HYUNDAI dealer for a cooling systeminspection.
G070101BUN
Recommended engine coolant
When adding coolant, use only deion-
ized water or soft water for your vehicle
and never mix hard water in the
coolant filled at the factory. An improp-
er coolant mixture can result in serious
malfunction or engine damage.
The engine in your vehicle has alu- minum engine parts and must be pro-
tected by an ethylene-glycol-based
coolant to prevent corrosion and freez-ing.
DO NOT USE alcohol or methanol coolant or mix them with the specifiedcoolant.
Do not use a solution that contains more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution. For mixture percentage, refer to the fol-
lowing table.
