3. Confirm if the fluid level is in “HOT” range on
the level gauge. If the fluid level is lower, add
the specified fluid from the fill hole. If the fluid
level is higher, drain the fluid from the drain
hole.
4. If the fluid level is checked in cold condition
(fluid temperature 68~86°F), add the fluid to
the “COLD” line and then recheck the fluid
level according to the above step 2.

CHECKING THE BRAKES
!
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 cooling 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. HOT

CAUTION:
Because brakes are essential to the safe
operation of the car, it is suggested that
they be checked and inspected by your
Hyundai dealer. The brakes should be
checked and inspected for wear at those
intervals specified in the vehicle mainte-
nance schedule in Section 5.

G130B02A-AATTo Replace the FluidRecommended 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 vehicle's
paint if spilled on it and not removed imme-
diately.
AIR CONDITIONING CAREG140A01A-AATKeeping the Condenser CleanThe air conditioning condenser (and engine
radiator) should be checked periodically for
accumulation of dirt, dead insects, leaves, etc.
These can interfere with maximum cooling ef-
ficiency. When removing such accumulations,
brush or hose them away carefully to avoid
bending the cooling fans.
HJM5007
CHECKING THE CLUTCH FLUIDG130A01A-AATTo Check the Clutch FluidThe 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
always 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 imme-
diately. Consult your Hyundai dealer.

!
G140C01A-AATLubricationTo lubricate the compressor and the seals in the
system, the air conditioning should be run for at
least 10 minutes each week. This is particularly
important during cool weather when the air
conditioning system is not otherwise in use.G140B01A-AATChecking the Air Conditioning Opera-
tion1. Start the engine and let it run at a fast idle for
several minutes with the air conditioning 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
extended periods of time with a low refrig-
erant level may damage the compressor.
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 the belt is too
loose, have it adjusted by your Hyundai dealer.
CHANGING THE CLIMATE CON-
TROL AIR FILTERB145A03JM-GAT(For Evaporator and Blower Unit)
(If Installed)The climate control air 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 support
strap through the hole.

CHECKING THE FREE-PLAYG150A01A-AATSTEERING WHEELTo check the steering wheel free-play, stop the
car with the wheels pointed straight ahead and
gently move the steering wheel back and forth.
Use very light finger pressure and be sensitive
to changes in resistance that mark the limits of
the free-play. If the free-play is greater than
specified, have it inspected by your Hyundai
dealer and adjusted or repaired if necessary.1.18 in.

CHECKING DRIVE BELTSDrive 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.G190A01A-AAT

CHECKING BRAKE PEDAL
CLEARANCEG180A01A-AATYou need a helper to check the brake pedal
clearance. With the engine running, have your
helper press down on the brake pedal several
times and then hold it down with a force of about
110 lbs (50 kg, 490 N). The brake pedal clear-
ance is the distance from the top surface of the
brake pedal to the asphalt sheeting under the
floor mat.
If the brake pedal clearance is not within the
limits specified in the illustration, have it in-
spected by your Hyundai dealer and adjusted
or repaired if necessary.2.95 in. (75 mm)

CHECKING AND REPLACING
FUSES
!
G200B02JM-AATReplacing Accessory Fuses
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.
The fuse box for the lights and other electrical
accessories will be found on the left side of
crash pad. 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:
G200A03A-AATReplacing a Fusible LinkA fusible link will melt if the electrical circuits from
the battery are ever overloaded, thus prevent-
ing 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 in the
engine compartement for easy inspection.

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 dealer.
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.
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 capac-
ity fuse could cause damage and create a
fire hazard.NOTE:See page 6-35 for the fuse panel descrip-
tions.
GoodOpen-Replace 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
relay and fuse box of the engine room to
simplify this operation).
3. Be sure to check all other fuses even if you
find one that appears to have opened.

POWER STEERING FLUID LEVELG230A03A-AAT
G220C01A-AAT
Checking Condenser Cooling FanThe condenser cooling fan should come on
automatically whenever the air conditioning is in
operation.
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.

matically if the engine coolant temperature is
high.
