System Maintenance
Climate control air filter
This filter is installed behind the glove
box. It filters the dust or other pollutants
that enter the vehicle through the heating
and air conditioning system.
Have the climate control air filter
replaced by an authorized HYUNDAI
dealer according to the maintenance
schedule. If the car is being driven in
severe conditions such as dusty or rough
roads, more frequent air conditioner filter
inspections and changes are required.
If the air flow rate suddenly decreases,
the system should be checked at an
authorized HYUNDAI dealer.
Checking the amount of air conditioner refrigerant andcompressor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning is
reduced. Overfilling also has a negative
influence on the air conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized HYUNDAI dealer.
It is important that the correct type
and amount of oil and refrigerant is
used. Otherwise, damage to the com-
pressor and abnormal system opera-
tion may occur. The air conditioning system should be
serviced by an authorized HYUNDAI
dealer.

wise damage to the vehicle and
personal injury may occur.

Winter Precautions
Use high quality ethylene glycolcoolant
Your vehicle is delivered with high quality
ethylene glycol coolant in the cooling
system. It is the only type of coolant that
should be used because it helps prevent
corrosion in the cooling system, lubri-
cates the water pump and prevents
freezing. Be sure to replace or replenish
your coolant in accordance with the
maintenance schedule in chapter 7.
Before winter, have your coolant tested to
assure that its freezing point is sufficient
for the temperatures anticipated during
the winter.
Change to "winter weight" oil ifnecessary
In some climates it is recommended that
a lower viscosity "winter weight" oil be
used during cold weather. See chapter 8
for recommendations. If you aren't sure
what weight oil you should use, consult
an authorized HYUNDAI dealer.
Check battery and cables
Winter puts additional burdens on the
battery system. Visually inspect the bat-
tery and cables as described in chapter
7. The level of charge in your battery can
be checked by an authorized HYUNDAI
dealer or a service station.
Check spark plugs and ignitionsystem
Inspect your spark plugs as described in
chapter 7 and replace them if necessary.
Also check all ignition wiring and compo-
nents to be sure they are not cracked,
worn or damaged in any way.
Use approved window washeranti-freeze in system
To keep the water in the window washer
system from freezing, add an approved
window washer anti-freeze solution in
accordance with instructions on the con-
tainer. Window washer anti-freeze is
available from an authorized HYUNDAI
dealer and most auto parts outlets. Do
not use engine coolant or other types of
anti-freeze as these may damage the
paint finish.
Do not let your parking brakefreeze
Under some conditions your parking
brake can freeze in the engaged position.
This is most likely to happen when there
is an accumulation of snow or ice around
or near the rear brakes or if the brakes
are wet. If there is a risk the parking
brake may freeze, apply it only temporar-
ily while you put the gear selector lever in
P and block the rear wheels so the car
cannot roll. Then release the parking
brake.
Do not let ice and snow accu-mulate underneath
Under some conditions, snow and ice
can build up under the fenders and inter-
fere with the steering. When driving in
severe winter conditions where this may
happen, you should periodically check
underneath the car to be sure the move-
ment of the front wheels and the steering
components is not obstructed.

You should exercise the utmost care to
prevent damage to your vehicle and
injury to yourself whenever performing
any maintenance or inspection proce-
dures.
We recommend you have your vehicle
maintained and repaired by an author-
ized HYUNDAI dealer. An authorized
HYUNDAI dealer meets HYUNDAI’s high
service quality standards and receives
technical support from HYUNDAI in
order to provide you with a high level of
service satisfaction.
Owner's Responsibility
Maintenance service and record reten-
tion are the owner's responsibility.
You should retain documents that show
proper maintenance has been performed
on your vehicle in accordance with the
scheduled maintenance service charts
shown on the following pages. You need
this information to establish your compli-
ance with the servicing and maintenance
requirements of your vehicle warranties.
Detailed warranty information is provided
in your Owner's Handbook & Warranty
Information booklet.
Repairs and adjustments required as a
result of improper maintenance or a lack
of required maintenance are not covered.
Owner Maintenance
Precautions
Inadequate, incomplete or insufficient
servicing may result in operational prob-
lems with your vehicle that could lead to
vehicle damage, an accident, or person-
al injury. This chapter provides instruc-
tions only for the maintenance items that
are easy to perform. Several procedures
can be done only by an authorized
HYUNDAI dealer with special tools.
Your vehicle should not be modified in
any way. Such modifications may
adversely affect the performance, safety
or durability of your vehicle and may, in
addition, violate conditions of the limited
warranties covering the vehicle.
Certain modifications may also be in vio-
lation of regulations established by the
U.S. Department of Transportation and
other federal or state agencies.
Improper owner maintenance during
the warranty period may affect war-
ranty coverage. For details, read the
separate Owner's Handbook &
Warranty Information booklet provid-
ed with the vehicle. If you're unsure
about any service or maintenance
procedure, have it done by an author-
ized HYUNDAI dealer.

Performing maintenance work on a
vehicle can be dangerous. 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.
ALWAYS follow these precautions
for performing maintenance work:
•Park your vehicle on level
ground, move the shift lever into
the P (Park, for automatic trans-
mission vehicle) position or neu-
tral (for manual transmission
vehicle), apply the parking brake,
place the ignition switch in the
LOCK/OFF position.
Block the tires (front and back) to
prevent the vehicle from moving.
Remove loose clothing or jewelry
that can become entangled in
moving parts.
If you must run the engine during
maintenance, do so out doors or
in an area with plenty of ventila-
tion.
Keep flames, sparks, or smoking
materials away from the battery
and fuel-related parts.

Maintenance
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 vehicle
checks are generally not covered by war-
ranties 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 coolant level in the enginecoolant reservoir.
Check the windshield washer fluid level.
Check 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 if there is 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 the automatic transmission/ dual clutch transmission P (Park) func-
tion.
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).
Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious burns
and other injuries.
