15CHECKING THE CLUTCH FLUID
!
G130B02A-AAT
To Replace the Fluid
Recommended brake fluid conforming to DOT 3
or DOT 4 specification should be used. The
reservoir cap must be fully tightened to avoid
contamination from foreign matter or moisture.
NOTE:Do not allow any other liquids to contami-
nate the brake fluid. Seal damage will result.
WARNING:Use caution when handling brake fluid. It
can damage your vision if you get it in your
eyes. It will also damage your vehicles paint
if spilled on it and not removed immediately.
G130A01A-AAT
To Check the Clutch Fluid
The clutch fluid level in the master cylinder
should be checked when performing other un-
der hood services. The system should be
checked for leakage at the same time.
Check to make certain that the clutch fluid level
is between the "MAX" and "MIN" level markings
on the fluid reservoir. Fill as required. Fluid loss
indicates a leak in the clutch system which
should be inspected and repaired immediately.
Consult your Hyundai dealer.

AIR CONDITIONER CARE
G140A01A-AAT
Keeping the Condenser Clean
The air conditioner condenser (and engine ra-
diator) should be checked periodically for accu-
mulation of dirt, dead insects, leaves, etc. These
can interfere with maximum cooling efficiency.
When removing such accumulations, brush or
hose them away carefully to avoid bending the
cooling fans.

Checking the Compressor Drive Belt
When the air conditioning is being used regular-
ly, 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 the belt is too
loose, have it adjusted by your Hyundai dealer.CRANK PULLEY

(If Installed)
The air conditioner filter is located in front of the
evaporator unit behind the glove box.
It helps to decrease the amount of pollutants
entering the car.
1. Open the glove box and remove the adjust-
ing pins on both sides of the glove box.
G140C01A-AAT
Lubrication
To lubricate the compressor and the seals in the
system, the air conditioner should be run for at
least 10 minutes each week. This is particularly
important during cool weather when the air con-
ditioning system is not otherwise in use.
G140B01A-AAT
Checking the Air Conditioner Opera-
tion
1. Start the engine and let it run at fast idle for
several minutes with the air conditioner set
at the maximum cold setting.
2. If the air coming out of the in-dash vents is
not cold, have the air conditioning system
inspected by your Hyundai dealer.
CAUTION:Running the air conditioning system for ex-
tended periods of time with a low refrigerant
level may damage the compressor.

FUSESCHECKING DRIVE BELTS
G190A01A-AAT
Drive belts should be checked periodically for
proper tension and adjusted if necessary. At the
same time, belts should be examined for cracks,
wear, fraying or other evidence of deterioration
and replaced if necessary.
Belt routing should also be checked to be sure
there is no interference between the belts and
other parts of the engine. After a belt is replaced,
the new belt should be adjusted again after two
or three weeks to eliminate slack resulting from
initial stretching after use.

Replacing a Fusible Link
A fusible link will melt if the electrical circuits
from the battery are ever overloaded, thus pre-
venting damage to the entire wiring harness.
(This could be caused by a short in the system
drawing too much current.) If this ever happens,
have a Hyundai dealer determine the cause,
repair the system and replace the fusible link.
The fusible links are located in a relay box for
easy inspection.

CAUTION:When replacing a fusible link, never use
anything but a new fusible link with the same
or lower amperage rating. Never use a piece
of wire or a higher-rated fusible link. This
could result in serious damage and create a
fire hazard.

CAUTION:An open fuse indicates that there is a prob-
lem in the electrical circuit. If you replace a
fuse and it blows as soon as the accessory
is turned on, the problem is serious and
should be referred to a Hyundai dealer for
diagnosis and repair. Never replace a fuse
with anything except a fuse with the same or
a lower amperage rating. A higher capacity
fuse could cause damage and create a fire
hazard.

Replacing Accessory Fuses
The fuse box for the lights and other electrical
accessories will be found low on the dashboard
on the driver's side. Inside the box you will find
a list showing the circuits protected by each
fuse.
If any of your car's lights or other electrical
accessories stop working, a blown (open) fuse
could be the reason. If the fuse has opened, you
will see that the metal strip inside the fuse has
melted through. If you suspect a blown fuse,
follow this procedure:
HLC4002
1. Turn off the ignition and all other switches.
2. Open the fuse box and examine each fuse.
Remove each fuse by pulling it toward you (a
small "fuse puller" tool is contained in the
fuse box to simplify this operation).
3. Be sure to check all other fuses even if you
find one that appears to have opened.
HLC4003
4. Replace the blown fuse by pressing a new
fuse of the same rating into place. The fuse
should be a snug fit. If it is not, have the fuse
clip repaired or replaced by a Hyundai deal-
er. If you do not have a spare fuse, you may
be able to borrow a fuse of the same or lower
rating from an accessory you can tempo-
rarily get along without (the radio or cigarette
lighter, for example). Always remember to
replace the borrowed fuse.
NOTE:See page 6-32 for the fuse panel descrip-
tions.

!
G210A01A-AAT
WARNING:When working with batteries, carefully ob-
serve the following precautions to avoid se-
rious injuries.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 pos-
sible.
While batteries are being charged (either by a
battery charger or by the vehicle's alternator),
they produce explosive gases. Always observe
these warnings to prevent injuries from occur-
ring:
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.

The fluid in the battery contains a strong solution
of sulfuric acid, which is poisonous and highly
corrosive. Be careful not to spill it on yourself or
the car. If you do spill battery fluid on yourself,
immediately do the following:
!
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 household bak-
ing 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. Batter-
ies also contain other chemicals known to
the State of California to cause cancer. Wash

POWER STEERING HOSES
It is suggested that you check the power steer-
ing hose connections for fluid leakage at those
intervals specified in the vehicle maintenance
schedule in Section 5.
The power steering hoses should be replaced if
there is severe surface cracking, pulling, scuff-
ing or worn spots. Deterioration of the hose
could cause premature failure.

Checking Engine Cooling Fan
The engine cooling fan should come on auto-
matically if the engine coolant temperature is
high.
WARNING:The radiator fan is controlled by engine cool-
ant temperature and may sometimes operate
even when the engine is not running. Use
extreme caution when working near the
blades of the cooling fan, so that you are not
injured by a rotating fan blade. As the cool-
ant temperature decreases the fan will auto-
matically shut off. This is a normal condition.
G220C01A-AAT
Checking Condenser Cooling Fan
The condenser cooling fan should come on
automatically whenever the air conditioner is in
operation.
HLC5006
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 conditions (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 character-
istic in extremely cold conditions.
