G130B02A-AATTo 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.
G140A01A-AAT
AIR CONDITIONER CARE
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.
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-AATChecking 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.
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.
!CAUTION:Running the air conditioning system for ex-
tended periods of time with a low refrigerant
level may damage the compressor.

G130A01A-AATCHECKING THE CLUTCH FLUID
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.

G140D01A-AATChecking 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 you have the
instruments to check it, with a force of 22 lb.
(98N), the deflection should be 0.315 inches
(approx. 8.0 mm). If the belt is too loose, have
it adjusted by your Hyundai dealer.CRANK PULLEY

G150A01A-AATCHECKING STEERING WHEEL
FREEPLAY
To check the steering wheel freeplay, 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 freeplay. If the freeplay is greater than speci-
fied, have it inspected by your Hyundai dealer
and adjusted or repaired if necessary.
G160A01A-AATCHECKING CLUTCH PEDAL
FREE-PLAY
With the engine off, press lightly on the clutch
pedal until you feel a change in resistance. This
is the clutch pedal free-play. The free-play should
be within the limits specified in the illustration
below. If it is not, have it inspected by your
Hyundai dealer and adjusted or repaired if nec-
essary.

G170A01A-AATCHECKING BRAKE PEDAL
FREE-PLAY
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 freeplay.
The freeplay should be within the limits specified
in the illustration above. If it is not, have it
inspected by your Hyundai dealer and adjusted
or repaired if necessary.

G190A01A-AATCHECKING DRIVE BELTS
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.

CLEARANCE
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.

G220B01A-AATChecking 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-AATChecking 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.
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 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.
Wash hands after handling.

G240A01A-AATPOWER 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.
