2. Remove the transaxle dipstick, wipe it clean,
reinsert the dipstick as far as it will go, then
remove it again. Now check the fluid level on
the dipstick. It should be in the "HOT" range
on the dipstick.
G110D02O-AATTo Check the Transaxle Fluid LevelPark the car on level ground with the parking
brake engaged. When the transaxle fluid level
is checked, the transaxle fluid should be at
normal operating temperature and the engine
idling.
While the engine is idling, apply the brakes and
move the gear selector lever from "P" to each
of its other positions — "R", "N", "D" — and then
return to "N" or "P". With the engine still idling:
1. Open the hood, being careful to keep hands,
long hair and clothing clear of any moving
parts.

WARNING:
The transaxle fluid level should be checked
when the engine is at normal operating
temperature. This means that the engine,
radiator, radiator hose, exhaust system etc.,
are very hot. Exercise great care not to burn
yourself during this procedure.

CHECKING THE BRAKES!
G120B01A-AATChecking the Brake Fluid Level
WARNING:Use caution when handling brake fluid. It
can damage your vision if it gets into your
eyes. It will also damage your vehicle's
paint if spilled on it and not removed imme-
diately.
!
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.Fluid level should be within "HOT" range
G120A01A-AAT
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.
!
3. If the transaxle fluid level is low, use a funnel
to add transaxle fluid through the dipstick
tube until the level reaches the "HOT" range.
Do not overfill.
G120D01A-AATTo Check the Fluid LevelThe fluid level in the brake fluid reservoir should
be checked periodically. The level should be
between the "MIN" and "MAX" marks on the side
of the reservoir. If the level is at or below the
"MIN" mark, carefully add fluid to bring it up to
"MAX". Do not overfill.G120C02A-AATRecommended Brake FluidUse only hydraulic brake fluid conforming to
DOT 3 or DOT 4 specifications in your braking
system. Follow the instructions printed on the
container.

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.
!
G120E02A-AATAdding Brake Fluid
WARNING:Handle brake fluid carefully. It can damage
your vision if it gets into your eyes. Use only
DOT 3 or DOT 4 specification fluid from a
sealed container. Do not allow the fluid can
or reservoir to remain open any longer than
required. This will prevent entry of dirt and
moisture which can damage the brake sys-
tem and cause improper operation.
To add brake fluid, first wipe away any dirt then
unscrew the fluid reservoir cap. Slowly pour the
recommended fluid into the reservoir. Do not
overfill. Carefully replace the cap on the reser-
voir and tighten.
AIR CONDITIONING CARE!
G140A01A-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.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.

CHANGING THE AIR
CONDITIONER FILTERB145A01NF-AAT(For Evaporator and Blower Unit)
(If Installed)The air conditioner filter is located in the right
side of the instrument panel.
It helps to decrease the amount of pollutants
entering the car.
1. Remove the cover (1) which is located to the
right side of the instrument panel by pulling
it.
2. Pull the glove box cylinder (2) to unlock the
glove box retainer.

4. Remove the air conditioner filter cover by
pressing both side clips.

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.

Then, using your hand, press down slowly on
the brake pedal until you feel a change in
resistance. This is the brake pedal free-play.
The free-play should be within the limits speci-
fied in the illustration above. If it is not, have it

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.

Drive belts should be checked periodically for
proper tension. At the same time, belts should
be examined for cracks, wear, fraying or other
evidence of deterioration and replaced if neces-
sary.
When a new belt is replaced, the belt should be
located within the pulley of flat idler.
Belt routing should also be checked to be sure
there is no interference between the belts and
other parts of the engine.
NOTE:Drive belt tension is adjusted automatically
by the auto tensioner.
CHECKING AND REPLACING
FUSESG200A01A-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 compartment for easy inspection.
HNF4004
!
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.

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
G200B02NF
find one that appears to have burned out.
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.
!
G200B02L
GoodBurned outCAUTION:
A burned-out fuse indicates that there is a
problem in the electrical circuit. If you re-
place 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 re-
place 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.NOTE:See page 6-39 for the fuse panel descrip-
tions.
G200B01NF-GATReplacing Accessory Fuse
G200B01NF-A
The fuse box for the lights and other electrical
accessories will be found on the left side of the
instrument panel. 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 fuse could
be the reason. If the fuse has burned out, you
will see that the metal strip inside the fuse has
burned through. If you suspect a blown fuse,
follow this procedure:
1. Turn off the ignition and all other switches.
