WARNING:
Never remove the radiator cap when the
engine is hot. The engine coolant is under
pressure and could erupt and cause severe
burns. Wait until the engine is cool before
adding coolant to the reservoir.
The needle on the engine coolant temperature
gauge should stay in the normal range. If it
moves across the dial to "H" (Hot), pull over and
stop as soon as possible and turn off the engine.
Then open the hood and check the coolant
reservoir level and the water pump drive belt. If
you suspect cooling system trouble, have your
cooling system checked by a Hyundai dealer as
soon as possible.

when the vehicle is moving. It may also be heard
when the brake pedal is pushed down firmly.
Excessive rotor damage will result if the worn
pads are not replaced. See your Hyundai dealer
immediately.

3- 4 WHAT TO DO IN AN EMERGENCY
!
!WARNING:While the engine is running, keep hair,
hands and clothing away from moving parts
such as the fan and drive belts to prevent
injury.
D040A02Y-AATSPARE TIRE
The following instructions for the temporary
spare tire should be observed:
1. Check inflation pressure as soon as practi-
cal after installing the spare tire, and adjust
to the specified pressure. The tire pressure
should be periodically checked and main-
tained at the specified pressure while the tire
is stored.
Tire Size
Inflation Pressure
T125/70D15, T125/70R15
60 psi (420 kPa) 5. If the water pump drive belt is broken or
engine coolant is leaking out, stop the engine
immediately and call the nearest Hyundai
dealer for assistance.
WARNING:Do not remove the radiator cap when the
engine is hot. This can allow coolant to be
blown out of the opening and cause seri-
ous burns.
6. If you cannot find the cause of the overheat-
ing, wait until the engine temperature has
returned to normal. Then, if coolant has been
lost, carefully remove the radiator cap and
add coolant to bring the fluid level in the
reservoir up to the halfway mark.
7. Proceed with caution, keeping alert for fur-
ther signs of overheating. If overheating
happens again, call a Hyundai dealer for
assistance.
CAUTION:Serious loss of coolant indicates there is a
leak in the cooling system and this should
be checked as soon as possible by a Hyundai
dealer.
!
4. As the temporary spare tire is specifically
designed for your car, it should not be used
on any other vehicle.
5. The temporary spare tire should not be used
on any other wheels, nor should standard
tires, snow tires, wheel covers or trim rings
be used with the temporary spare wheel. If
such use is attempted, damage to these
items or other car components may occur.
6. The temporary spare tire pressure should
be checked once a month while the tire is
stored.

G050D02A-AATTo Change the Engine CoolantThe engine coolant should be changed at those
intervals specified in the vehicle maintenance
schedule in Section 5.
G050C01A-AAT
To Check the Coolant LevelThe coolant level can be seen on the side of the
plastic coolant reservoir. The level of the cool-
ant should be between the "L" and "F" lines on
the reservoir when the engine is cool. If the level
is below the "L" mark, add engine coolant to
bring it up between "L" and "F". If the level is low,
inspect for coolant leaks and recheck the fluid
level frequently. If the level drops again, visit
your Hyundai dealer for an inspection and
diagnosis of the reason.Ambient

G050B01A-AATRecommended Engine Coolant
Use a high quality ethylene-glycol coolant in a
50/50 mix with water. The engine coolant should
be compatible with aluminum engine parts.
Additional corrosion inhibitors or additives should
not be used. The cooling system must be
maintained with the correct concentration and
type of engine coolant to prevent freezing and
corrosion. Never allow the concentration of
antifreeze to exceed the 60% level or go below
the 35% level, or damage to the cooling system
may result. For proper concentration when
adding or replacing the engine coolant, refer to
the following table.
G050B01Y
CAUTION:Engine coolant can damage the finish of
your car. If you spill engine coolant on the
car, wash it off thoroughly with clean water.
1. Park the car on level ground, set the park-
ing brake and remove the radiator cap when
cool.
2. Be sure your drain receptacle is in place.
Open the drain cock on the radiator. Allow all
the engine coolant to drain from the cooling
system, then securely close the drain cock.
3. Check Section 9 for the capacity of the
cooling system in your car. Then, following
the manufacturer's directions on the engine
coolant container, add the appropriate quan-
tity of coolant to the radiator.

4. Turn the radiator cap counterclockwise with-
out pressing down on it, until it stops. This
relieves any pressure remaining in the cool-
ing system. And remove the radiator cap by
pushing down and turning counterclock-
wise.
Now fill the radiator with clean demineralized
or distilled water. Continue to add clean
demineralized or distilled water in small quan-
tities until the fluid level stays up in the
radiator neck.
5. Start the engine, top off the radiator with
water and then add coolant to the reservoir
until the level is between "L" and "F".
6. Replace the radiator and reservoir caps and
check to be sure the drain cocks are fully
closed and not leaking.G060A02Y-AATSPARK PLUGS
Your engine was originally equipped with plati-
num-tipped spark plugs.
Platinum-tipped spark plugs will last longer than
conventional type spark plugs and can be
identified by blue lines on the ceramic shell.
NOTE:Do not clean or regap platinum-tipped spark
plugs.
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.
HSM392G060B04Y-AAT
Replacing the Spark PlugsThe spark plugs should be changed at the
intervals specified in the vehicle maintenance
schedule in Section 5 or whenever engine
performance indicates they should be changed.
Symptoms that suggest poor spark plug perfor-
mance include engine misfiring under load, loss
of fuel economy, poor acceleration, etc. When
spark plugs are replaced, always use spark
plugs recommended by Hyundai. The use of
other spark plugs can result in loss of perfor-
mance, radio interference or engine damage.
NOTE:When replacing the spark plugs, always use
the genuine parts recommended.

G070A03Y-AATCHANGING THE AIR CLEANER FILTER
The replacement of air cleaner filter is per-
formed in the following manner.
1. Unsnap the clips around the cover.
2. When this is done, the cover can be lifted off,
the old filter removed and the new filter put in
its place.
Genuine Hyundai replacement parts are rec-
ommended.
G080A02A-AATWINDSHIELD WIPER BLADES
The wiper blades should be carefully inspected
from time to time and cleaned to remove accu-
mulations of road film or other debris. To clean
the wiper blades and arms, use a clean sponge
or cloth with a mild soap or detergent and water.
If the wipers continue to streak or smear the
glass, replace them with genuine Hyundai re-
placement parts or their equivalent.
NOTE:o Do not operate the wipers on dry glass.
This can result in more rapid wear of the
wiper blades and may scratch the glass.
o Keep the blade rubber out of contact
with petroleum products such as engine
oil, gasoline, etc.
G090A01A-AATFILLING THE WASHER RESERVOIR
The washer fluid reservoir supplies fluid to the
windshield washer system.
A good quality washer fluid should be used to fill
the washer reservoir. The fluid level should be
checked more frequently during bad weather or
whenever the washer system is in more fre-
quent use.
The capacity of the washer reservoir is 3.2 U.S.
quarts (3.0 Liters).
CAUTION:Operating your vehicle without using a
proper air cleaner filter in place can result in
excessive engine wear.
CAUTION:o Radiator anti-freeze (engine coolant)
should not be used in the washer system
because it will damage the car’s finish.
o The washer lever should not be pulled
and the washer should not be operated
if the washer reservoir is empty. This can
damage the washer fluid pump.

G210B02A-AATChecking 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. 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.
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.
The power steering fluid level should be checked
regularly. To check the power steering fluid
level, be sure the engine is "OFF", then check
to make certain that the power steering fluid
level is between the "MAX" and "MIN" level
markings on the fluid reservoir.
NOTE:Grinding noise from the power steering
pump may be heard immediately after the
engine is started in extremely cold condi-
tions (below - 4°F). If the noise stops during
warm up, there is no abnormal function in
the system. It is due to a power steering
fluid characteristic in extremely cold condi-
tions.
