OOWW NNEERR MM AAIINN TTEENN AANN CCEE
The following lists are vehicle checks and inspections that should be per-
formed by the owner or an author-
ized HYUNDAI dealer at the frequen-
cies indicated to help ensure safe,
dependable operation of your vehi-
cle.
Any adverse conditions should be
brought to the attention of your deal-
er as soon as possible.
These Owner Maintenance vehicle
checks are generally not covered by
warranties and you may be charged
for labor, parts and lubricants used.
Performing maintenance work
on a vehicle can be dangerous.
If you lack sufficient knowledge
and experience or the propertools and equipment to do the
work, have it done by an author-
ized HYUNDAI dealer.
ALWAYS follow these precau-
tions for performing mainte-
nance work:
•Park your vehicle on level
ground, move the shift lever
into the P (Park, for automatic
transmission vehicle) position
or neutral (for manual trans-
mission vehicle), apply the
parking brake, place the igni-
tion switch in the LOCK/OFFposition.
(Continued)
WARNING (Continued)
Block the tires (front and
back) to prevent the vehicle
from moving.
Remove loose clothing or jew-
elry that can become entan-
gled in moving parts.
If you must run the engine
during maintenance, do so
out doors or in an area withplenty of ventilation.
Keep flames, sparks, or smok-
ing materials away from the
battery and fuel-related parts.

Maintenance
Owner Maintenance Schedule
When you stop for fuel:
Check the engine oil level.
Check the coolant level in theengine coolant reservoir.
Check the windshield washer fluid level.
Check the tire for low or under- inflated tires.
While operating your vehicle:
Note any changes in the sound ofthe exhaust or any smell of
exhaust fumes in the vehicle.
Check for vibrations in the steering wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead posi-tion.
Notice if your vehicle constantly turns slightly or "pulls" to one side
when traveling on smooth, levelroad.
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 operation of your transmission
occurs, check the transmission
fluid level.
Check the automatic transmission/ dual clutch transmission P (Park)function. Check the parking brake.
Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
Check coolant level in the enginecoolant reservoir.
Check the operation of all exterior lights, including the brake lights,
turn signals and hazard warning
flashers.
Check the inflation pressures of all tires including the spare for tires
that are worn, show uneven wear,or are damaged.
Check for loose wheel lug nuts.
Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of theopening and cause serious
burns and other injuries.

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 Filter
A clogged-up fuel filter may limit the
vehicle driving speed, damage theemission system, and cause the
hard starting. When a considerable
amount of foreign substances are
accumulated in the fuel tank, the fuelfilter should be replaced.
Upon installing a new fuel filter, oper-
ate the engine for several minutes,
and check the connections for any
leakages. Fuel filters should be
installed by an authorized HYUNDAI
dealer.
Fuel Lines, Fuel Hoses and Connections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. Have an authorized HYUNDAI
dealer replace any damaged or leak-
ing parts immediately.
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 a new vaporhose or fuel filler cap is correctlyreplaced.
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 ensure that 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.

Maintenance
Air Cleaner Filter
A genuine HYUNDAI air cleaner filter is recommended when the filter isreplaced.
Spark Plugs
Make sure to install new spark plugs
of the correct heat range.
Cooling System
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Engine Coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Automatic Transmission Fluid (if equipped)
Automatic transmission fluid should
not be checked under normal usage
conditions. But in severe conditions,the fluid should be changed at an
authorized HYUNDAI dealer inaccordance to the scheduled mainte-nance at the beginning of this chap-
ter.
Automatic transmission fluid
color is red when new.
As the vehicle is driven, the auto- matic transmission fluid will begin
to look darker. This is a normal
condition and you should not
judge the need to replace the fluid
based upon the changed color.
Dual Clutch Transmission Fluid (if equipped)
Inspect the dual clutch transmission fluid according to the maintenance
schedule.
Manual Transmission Fluid (if equipped)
Inspect the manual transmission fluid according to the maintenance
schedule.
NOTICE
The use of a non-specified fluid could result in transmission
malfunction and failure. Use
only the specified automatic
transmission fluid (refer to"Recommended Lubricants and
Capacities" in chapter 8).

Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.
Brake/Clutch Fluid
Check the brake/clutch fluid level in
the brake/clutch fluid reservoir. The
level should be between the MIN and
the MAX marks on the side of the
reservoir. Use only hydraulic
brake/clutch fluid conforming to DOT
3 or DOT 4 specification.
Parking Brake
Inspect the parking brake system
including the parking brake pedal
and cables.
Brake Discs, Pads, Calipers

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 level at least once a year, atthe beginning of the winter season
and before traveling to a colder cli-
mate.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 the F and the L marks on
the side of the coolant reservoirwhen the engine is cool.
If the coolant level is low, add enough
distilled (deionized) water to bring
the level to the F mark, but do not
overfill. If frequent additions are
required, see an authorized
HYUNDAI dealer for a cooling sys-tem inspection.
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.
An improper coolant mixture can result in severe 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.

Maintenance
Do not use a solution that containsmore than 60% antifreeze or less
than 35% antifreeze, which would
reduce the effectiveness of thesolution.
For mixing 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.
