Convenient features of your vehicle
•Operating the air conditioning sys-
tem in the recirculated air position
provides maximum cooling, how-
ever, continual operation in this
mode may cause the air inside the
vehicle to become stale.
•During cooling operation, you may
occasionally notice a misty air flow
because of rapid cooling and
humid air intake. This is a normal
system operation characteristics.
System maintenance
Climate control air filter
The climate control air filter installed
behind the glove box filters the dust
or other pollutants that come into the
vehicle from the outside through the
heating and air conditioning system.
If dust or other pollutants accumulate
in the filter over a period of time, the
air flow from the air vents may
decrease, resulting in moisture accu-
mulation on the inside of the wind-
shield even when the outside (fresh)
air position is selected. If this hap-
pens, we recommend that the cli-
mate control air filter be replaced by
an authorized HYUNDAI dealer.
Information
• Replace the filter according to the
Maintenance Schedule.
If the car is being driven in severe con-
ditions such as dusty, rough roads,
more frequent climate control air filter
inspections and changes are required.
• When the air flow rate suddenly
decreases, we recommend that the
system be checked by an authorized
HYUNDAI dealer.
Information
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.

Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is
low, the performance of the air con-
ditioning is reduced. Overfilling also
has a bad influence on the air condi-
tioning system.
Therefore, if abnormal operation is
found, we recommend that the sys-
tem be inspected by an authorized
HYUNDAI dealer.

Because the refriger-
ant is at very high
pressure, the air con-
ditioning system
should only be serv-
iced by trained and certified
technicians. It is important that
the correct type and amount of
oil and refrigerant is used.
Otherwise, it may cause damage
to the vehicle and personal injury.
WARNING

Driving your vehicle
Carbon monoxide (CO) gas is toxic. Breathing CO can cause unconsciousness and death.
Engine exhaust contains carbon monoxide which cannot be seen or smelled.
Do not inhale engine exhaust.
If at any time you smell engine exhaust inside the vehicle, open the windows immediately. Exposure to CO can causeunconsciousness and death by asphyxiation.
Be sure the exhaust system does not leak.
The exhaust system should be checked whenever the vehicle is raised to change the oil or for any other purpose. Ifyou hear a change in the sound of the exhaust or if you drive over something that strikes the underneath side of thevehicle, we recommend that the exhaust system be checked as soon as possible by an authorized HYUNDAI dealer.
Do not run the engine in an enclosed area.
Letting the engine idle in your garage, even with the garage door open, is a hazardous practice. Run the engine onlylong enough to start the engine and to move the vehicle out of the garage.
Avoid idling the engine for prolonged periods with people inside the vehicle .
If it is necessary to idle the engine for a prolonged period with people inside the vehicle , be sure to do so only in anopen area with the air intake set at "Fresh" and fan control set to high so fresh air is drawn into the interior.
Keep the air intakes clear.

If you must drive with the trunk open:
Close all windows.
Open instrument panel air vents.
Set the air intake control at "Fresh", the air flow control at "Floor" or "Face", and the fan control set to high.

Driving your vehicle
Check battery and cables
Winter puts additional burdens on
the battery system.Visually inspect
the battery and cables as
described in chapter 7.We recom-
mend that the level of charge in your
battery be checked by an authorized
HYUNDAI dealer.
Change to "winter weight" oil if
necessary
In some climates it is recommended
that a lower viscosity "winter weight"
oil be used during cold weather. See
section 8 for recommendations. If
you aren't sure what weight oil you
should use, we recommend that you
consult an authorized HYUNDAI
dealer.
Check spark plugs and ignition
system
Inspect your spark plugs as
described in section 7 and replace
them if necessary. Also check all
ignition wiring and components to be
sure they are not cracked, worn or
damaged in any way.
To keep locks from freezing
To k e e p t h e l o c k s f r o m f r e e z i n g ,
squirt an approved de-icer fluid or
glycerine into the key opening. If a
lock is covered with ice, squirt it with
an approved de-icing fluid to remove
the ice. If the lock is frozen internally,
you may be able to thaw it out by
using a heated key. Handle the heat-
ed key with care to avoid injury.
Use approved window washer
anti-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 instruc-
tions on the container. Window wash-
er 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.

Maintenance
Owner maintenance schedule
When you stop for fuel:
•Check the engine oil level.
•Check coolant level in the engine
coolant 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 loose-
ness in the steering wheel, or
change in its straight-ahead position.
•Notice if your vehicle constantly
turns slightly or “pulls” to one side
when traveling 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
operation of your transaxle occurs,
check the transaxle fluid level.
•Check the automatic transaxle
P (Park) function.
•Check the parking brake.
•Check for fluid leaks under your vehi-
cle (water dripping from the air con-
ditioning system during or after use
is normal).
At least monthly:
•Check coolant level in the engine
coolant reservoir.
•Check the operation of all exterior
lights, including the stoplights, 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 the
opening and cause serious
burns and other injuries.

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 frequent oil and filter changes
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 (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 excessive amount of
foreign matter accumulates 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.
We recommend that the fuel filter be
replaced by an authorized HYUNDAI
dealer.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. We recommend that the fuel
lines, fuel hoses and connections be
replaced by an authorized HYUNDAI
dealer.
Va p o r h o s e a n d f u e l f i l l e r c a p
The vapor hose and fuel filler cap
should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure that a new
vapor hose or fuel filler cap is cor-
rectly replaced.
When you are inspecting the
belt, place the ignition switch to
the LOCK/OFF or ACC position.
CAUTION
