OWNER MAINTENANCE
The following lists are vehicle checks and
inspections that should be performed by
the owner or an authorized HYUNDAIdealer 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
When you stop for fuel:
 Check the engine oil level.
 Check the coolant level in coolant
reservoir.
 Check the windshield washer fluid level.
 Look for low or under-inflated tires.
While operating your vehicle:
 Note any changes in the sound of the exhaust 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-aheadposition.
 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 transaxle occurs, check
the transaxle fluid level.
 Check automatic transaxle P (Park) function.
 Check the parking brake.
 Check for fluid leaks under your vehicle (water dripping from the air condition-
ing system during or after use is nor-mal).
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.

EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
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. 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. Fuel filter (cartridge) 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.
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.
WARNING -
Diesel only
Never work on the injection system with the engine running or within30 seconds after shutting off the
engine. High pressure pump, rail,
injectors and high pressure pipes
are subject to high pressure even
after the engine stops. The fuel jet
produced by fuel leaks may cause
serious injury, if it touches the
body. People using pacemakers
should not move more than 30cm
closer to the ECU or wiring harness
within the engine room while the
engine is running, since the highcurrents in the Common Rail sys-
tem produce considerable magnet-ic fields.

Maintenance
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.
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.Air cleaner filter
A Genuine HYUNDAI air cleaner filter is recommended when the filter isreplaced.
Spark plugs (for gasoline engine)
Make sure to install new spark plugs of
the correct heat range.
Valve clearance (if equipped)
Inspect for excessive valve noise and/or
engine vibration and adjust if necessary.
An authorized HYUNDAI dealer should
perform the operation.
Cooling system
Check cooling system components, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts. Coolant The coolant should be changed at the
intervals specified in the maintenance
schedule.
Manual transaxle fluid (if equipped)
Inspect the manual transaxle fluid
according to the maintenance schedule.

Automatic transaxle fluid (if equipped)
The fluid level should be in the "HOT"
range of the dipstick, after the engine
and transaxle are at normal operating
temperature. Check the automatic
transaxle fluid level with the engine run-
ning and the transaxle in neutral, with the
parking brake properly applied. 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 brake fluid level in the brake fluid
reservoir. The level should be between
“MIN” (Minimum) and “MAX” (Maximum)
marks on the side of the reservoir. Use
only hydraulic brake fluid conforming to
DOT 3 or DOT 4 specification. Parking brake
Inspect the parking brake system includ-
ing the parking brake pedal and cables.
Brake discs, pads, calipers and
rotors
Check the pads for excessive wear, discs
for run out and wear, and calipers for fluid
leakage.
For more information on checking the
pads or lining wear limit, refer to the
Hyundai web site. (

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 engine off,
check for excessive free-play in the
steering wheel.
Check the linkage for bends or damage.

ENGINE OIL
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 reinsert it fully.
5. Pull the dipstick out again and check the level. The level should be between
F (Full) and L (Low). If it is near or at L (Low), add enough oil
to bring the level to F (Full).
Do not over-
fill.
Use a funnel to help prevent oil from being spilled on engine components.
Use only the specified engine oil. (Refer
to “Recommended lubricants and capac-
ities” 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.
CAUTION
Do not overfill the engine oil. It may damage the engine.
CAUTION - Diesel engine
Overfilling the engine oil may cause
severe dieseling due to churning effect. It may lead to engine damageaccompanied with abrupt engine
speed increment, combustion noiseand white smoke emission.

Maintenance
Changing the engine oil and filter
Have the engine oil and filter changed by
an authorized HYUNDAI dealer accord-ing to the Maintenance Schedule at thebeginning of this section.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.
Checking the coolant level
WARNING
Used engine oil may cause skin irri- tation or cancer if left in contact
with the skin for prolonged periods
of time. Used engine oil contains
chemicals that have caused cancer
in laboratory animals. Always pro-
tect your skin by washing your
hands thoroughly with soap and
warm water as soon as possibleafter 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. Also hot coolant orsteam could cause serious per-
sonal injury.
(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.

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 (Full) and L (Low) marked on
the side of the coolant reservoir when theengine is cool.
If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the
level to F (Full), but do not overfill. If fre-quent additions are required, see an
authorized HYUNDAI dealer for a coolingsystem inspection.
Recommended engine coolant
 Use only soft (distilled) water in the
coolant mixture.
 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.
