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.
G110D03Y
Fluid level should be within "HOT" range
4. 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.
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.
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
to "N" with the engine still idling:
1. Open the hood, being careful to keep hands,
long 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.
3. Return the gear selector to the "P" position.
HXG556J
!
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.

AIR CONDITIONING CARE
G140D02A-AATChecking the Compressor Drive BeltWhen 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.

Crank shaft pulley
A/C pulley Power steering pulley
Generator
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.
!
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.

CHANGING THE AIR CONDITIONER
FILTERG145A02L-GAT(For Evaporator and Blower Unit)The air conditioner filter is located in front of the
evaporator unit behind the glove box.
It helps to decrease pollutants from entering the
car.

1. Open the glove box and take out the damper
strap from the hole.2. Lower the glove box completely by pushing
the both sides of the glove box inward.3. Lower the glove box down completely.
4. Turn the knob of the air conditioner filter
cover counterclockwise and remove the air
conditioner filter cover.

CHECKING THE FREEPLAY
G170A01A-AATCHECKING BRAKE PEDAL
FREE-PLAYWith 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
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
inspected by your Hyundai dealer and adjusted
or repaired if necessary.

G150A01A-AATCHECKING STEERING WHEEL
FREE-PLAYTo 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.

5. Remove the two air conditioner filters by
pulling the knob of the air conditioner filter
outward.
6. Replace the two filters.
7. Installation is the reverse order of disassem-
bly.
CAUTION:
Be sure to install it with the direction of the
air conditioner filter checked.

POWER STEERING FLUID LEVEL
CHECKING ELECTRIC COOLING
FANS!
G250A01A-AATFOR MORE INFORMATION ABOUT
YOUR HYUNDAIIf 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 HOSESIt 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.
G230A01L-AAT
G220B01A-AAT
Checking Engine Cooling FanThe engine cooling fan should come on auto-
matically if the engine coolant temperature is
high.G220A01A-AAT
G220C01A-AATChecking Condenser Cooling FanThe 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.
The power steering fluid level should be checked
regularly.
To check the power steering fluid level, be sure
the ignition 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.
HXG2006
Recommended FluidUse PSF-3 fluid.NOTE:Do not start the engine when the power
steering oil reservoir is empty.

CATALYTIC CONVERTER
!
WARNING:
o Use unleaded fuel only.
o Maintain the engine in good operating
condition. Extremely high catalytic con-
verter temperatures can result from im-
proper operation of the electrical, igni-
tion or multiport electronic fuel injec-
tion.
o If your engine stalls, pings, knocks, or is
hard to start, have your Hyundai dealer
inspect and repair the problem as soon
as possible.
o Avoid driving with a very low fuel level.
Running out of gasoline may cause the
engine to misfire and result in damage to
the catalytic converter.
o Avoid idling the engine for periods
longer than 10 minutes.
o The vehicle should not be pushed or
pulled to get started. This may cause the
catalytic converter to overheat and cre-
ate a fire hazard.
H020A01A-AATAll Hyundai vehicles are equipped with a mono-
lith type three-way catalytic converter to re-
duce the carbon monoxide, hydrocarbons and
nitrogen oxides contained in the exhaust gas.
Exhaust gases passing through the catalytic
converter cause it to operate at a very high
temperature. The introduction of large amounts
of unburned gasoline into the exhaust may
cause the catalytic converter to overheat and
create a fire hazard. This risk may be reduced
by observing the following:Catalytic Converter
H020A01L
H010E01Y-AATEGR System (If Installed)This system helps reduce nitrogen oxides by
recirculating a part of the exhaust gas into the
engine, thereby reducing cylinder combustion
temperature, which results in lower output of
oxides of nitrogen.H010D01A-AAT3. Exhaust Emission Control SystemThe Exhaust Emission Control System is a
highly effective system which controls exhaust
emissions while maintaining good vehicle per-
formance.
