CHECKING THE FREEPLAY
G160A01A-AAT
Clutch Pedal
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 illus-
tration. If it is not, have it inspected by your
Hyundai dealer and adjusted or repaired if
necessary.
G160A01E
0.24 ~ 0.51 in.
(6 ~ 13 mm)
G150A01A-AAT
Steering wheel
To 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.

23CHECKING ELECTRIC COOLING
FANS
!
!
G220B01A-AATChecking Engine Cooling Fan
The engine cooling fan should come on auto-
matically if the engine coolant temperature is
high.
G220A01A-AAT
G220C01A-AAT
Checking Condenser Cooling Fan
The condenser coolant fan should come on
automatically whenever the air conditioning is in
operation.
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 coolant 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.
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 house-
hold baking 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. 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
possible.
While batteries are being charged (either by a
battery charger or by the vehicle's generator),
they produce explosive gases. Always ob-
serve these warnings to prevent injuries from
occurring:
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.

24POWER STEERING FLUID LEVEL
G230A03A-AAT
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.

HEADLIGHT AIMING ADJUSTMENT
G250A01A-AATFOR MORE INFORMATION ABOUT
YOUR HYUNDAI
If you desire additional information about main-
taining and servicing your Hyundai, you may
purchase a factory Shop Manual at your Hyundai
dealer's parts department. This is the same
manual used by dealership technicians and
while it is highly technical it can be useful in
obtaining a better understanding of your car and
how it works.
G240A01A-AATPOWER STEERING HOSES
It is suggested that you check the power steer-
ing hose connections for fluid leakage at regular
intervals. The power steering hoses should be
replaced if there is severe surface cracking,
scuffing or worn spots. Deterioration of the hose
could cause premature failure.
Recommended FluidUse PSF-3 type fluid
NOTE:Do not start the engine when the power
steering oil reservoir is empty.
G290A03E-AATBefore performing aiming adjustment, make
sure of the following.
1. Keep all tires inflated to the correct pressure.
2. Place the vehicle on level ground and press
the front bumper & rear bumper down sev-
eral times. Place the vehicle at a distance of
118 in. (3,000 mm) from the test wall.
3. See that the vehicle is unloaded (except for
full levels of coolant, engine oil and fuel, and
spare tire, jack, and tools). Have the driver
or equivalent weight placed in driver's seat.
4. Clean the head light lenses and turn on the
headlights (Low beam).
