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", "2", "L" -- and
then return to "N" or "P". With the engine still
idling:
1. Open the hood, being careful to keep hands,
hair and clothing clear of any moving parts.
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.
G110D03A G110D02A-AAT
To Check the Transaxle Fluid Level
Park 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.

!
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.
G110D04A
Fluid level should be within
"HOT" range
WARNING:The cooling fan is controlled by the engine
coolant temperature and may sometimes op-
erate 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 engine
coolant temperature decreases, the fan will
automatically shut off. This is a normal con-
dition.

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.

G140D02A-AAT
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

(For Evaporator and Blower Unit)
(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.

Brake Pedal
With the engine off, press down on the brake
pedal several times to reduce the vacuum in the
brake booster.
Then, using your hand, press down slowly on
the brake pedal until you feel a change in resis-
tance. 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
inspected by your Hyundai dealer and adjusted
or repaired if necessary.

You 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.

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.

Good
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.

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.
