TENSION PULLEY
When the air conditioning is being used regu-
larly, the compressor drive belt tension should
be checked at least once a month with the
engine turned off.
To check the drive belt tension, press down on
the belt halfway between the engine crankshaft
and compressor pulleys. Pressing with your
finger, you should not be able to deflect this belt
anymore than 1/3 of an inch. If you have the
instruments to check it, with a force of 22 lb.
(98N), the deflection should be 0.315 inches
(approx 8.0 mm). If the belt is too loose, have it
adjusted by your Hyundai dealer.

CHANGING THE AIR FILTER
HXD2096 B140E01E-AAT
(For Evaporator and Blower Unit)
(If Installed)
The air filter is located in front of the evaporator
unit behind the glove box.
It helps to decrease pollutants from entering the
car and to filter the air.
2. Remove the mounting bolts with the socket
wrench, and then detach the mounting
bracket.
1. Open the glove box and remove the adjust-
ing pins on both sides of the glove box.

G220B01A-AATChecking Engine Cooling Fan
The engine cooling fan should come on auto-
matically if the engine coolant temperature is
high.
G220A01A-AAT
G220C01A-AAT
Checking Condenser Cooling Fan
The condenser coolant fan should come on
automatically whenever the air conditioning is in
operation.
WARNING:The cooling fan is controlled by engine
coolant temperature and may sometimes
operate even when the engine is not run-
ning. Use extreme caution when working
near the blades of the coolant fan, so that
you are not injured by a rotating fan blade.
As the engine coolant temperature de-
creases the fan will automatically shut off.
This is a normal condition.
G210B02A-AAT
Checking the Battery
Keep the battery clean. Any evidence of corro-
sion around the battery posts or terminals
should be removed using a solution of house-
hold baking soda and warm water. After the
battery terminals are dry, cover them with a light
coating of grease.
PROPOSITION 65 WARNING:Battery posts, terminals, and related acces-
sories contain lead and lead compounds,
chemicals known to the state of California
to cause cancer and reproductive harm.
Wash hands after handling. o If battery fluid is on your skin, flush the
affected areas with water for at least 15
minutes and then seek medical assistance.
o If battery fluid is in your eyes, rinse out your
eyes with water and get medical assistance
as soon as possible. While you are being
driven to get medical assistance, continue to
rinse your eyes by using a sponge or soft
cloth saturated with water.
o If you swallow battery fluid, drink a large
quantity of water or milk followed by milk of
magnesia, eat a raw egg or drink vegetable
oil. Get medical assistance as soon as
possible.
While batteries are being charged (either by a
battery charger or by the vehicle's generator),
they produce explosive gases. Always ob-
serve these warnings to prevent injuries from
occurring:
o Charge batteries only in a well ventilated
area.
o Do not permit flames, sparks or smoking in
the area.
o Keep children away from the area.

7EMISSION CONTROL SYSTEMS
3CATALYTIC CONVERTER
!!WARNING:o Use unleaded fuel only.
o Maintain the engine in good operating
condition. Extremely high catalytic con-
verter temperatures can result from im-
proper operation of the electrical, igni-
tion or multiport electronic fuel injec-
tion.
o If your engine stalls, pings, knocks, or is
hard to start, have your Hyundai dealer
inspect and repair the problem as soon
as possible.
o Avoid driving with a very low fuel level.
Running out of gasoline may cause the
engine to misfire and result in damage to
the catalytic converter.
o Avoid idling the engine for periods
longer than 10 minutes.
o The vehicle should not be pushed or
pulled to get started. This may cause the
catalytic converter to overheat and cre-
ate a fire hazard.
o Do not touch the catalytic converter or
any other part of the exhaust system
while the catalytic converter is hot. Shut
off the engine, wait for at least one hour
before touching the catalytic converter
or any other part of the exhaust system.
o Remember that your Hyundai dealer is
your best source of assistance.
H020A01S-AAT
All Hyundai vehicles are equipped with one or
two monolith type three-way catalytic convert-
ers to reduce the carbon monoxide, hydrocar-
bons and nitrogen oxides contained in the ex-
haust gas. Exhaust gases passing through the
catalytic converter cause it to operate at a very
high temperature. The introduction of large
amounts of unburned gasoline into the exhaust
may cause the catalytic converter to overheat
and create a fire hazard. This risk may be
reduced by observing the following:
WARNING:o Do not stop your Hyundai over any com-
bustible material such as grass, paper,
leaves or rags. These materials might
contact the hot catalytic converter and a
fire might result.

SNOW TIRES
If you equip your car with snow tires, they should
be the same size and have the same load
capacity as the original tires. Snow tires should
be installed on all four wheels; otherwise, poor
handling may result.
Snow tires should carry 4 psi (28 kPa) more air
pressure than the pressure recommended for
the standard tires on the tire label on the driver
side center pillar outer panel, or up to the
maximum pressure shown on the tire sidewall
whichever is less.
Do not drive faster than 75 mph (120 km/h)
when your car is equipped with snow tires.
I030A02S-AAT
RECOMMENDED INFLATION
PRESSURES
The tire label located on the driver's side center
pillar outer panel gives the tire pressures rec-
ommended for your vehicle.These pressures were chosen to provide the
most satisfactory combination of ride comfort,
tire wear and stability under normal conditions.
Tire pressures should be checked at least
monthly. Proper tire inflation pressures should
be maintained for these reasons:
o Lower-than-recommended tire pressures
cause uneven tread wear and poor handling.
o Higher-than-recommended tire pressures
increase the chance of damage from im-
pacts and cause uneven tread wear.
CAUTION:Always observe the following:
o Check pressures when the tires are cold.
That is, after the car has been parked for
at least three hours and hasn't been
driven more than one mile or 1.6 km since
starting up.
o Check the pressure of your spare tire
each time you check the pressure of
other tires.
o Never overload your car. Be especially
careful about overloading if you equip
your car with a luggage rack or car top
carrier.
