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.
CHECKING AND REPLACING
FUSESG200A01GK-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(2.0L
)or below the positive (+) post cover of the
battery (2.7L) for easy inspection.

!
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.

CHECKING ELECTRIC COOLING
FANS!
G220A01A-AAT
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.
WARNING:Always read the following in-
structions carefully when han-
dling a battery.
Keep lighted cigarettes and all
other flames or sparks away from
the battery.
Hydrogen, which is a highly com-
bustible gas, is always present in
battery cells and may explode if
ignited.
Keep batteries out of the reach of
children because batteries con-
tain highly corrosive SULFURIC
ACID. Do not allow battery acid
to contact your skin, eyes, cloth-
ing or paint finish.
If any electrolyte gets into your
eyes, flush your eyes with clean
water for at least 15 minutes and
get immediate medical attention.
If possible, continue to apply
water with a sponge or cloth until
medical attention is received.If electrolyte gets on your skin,
thoroughly wash the contacted
area.
If you feel a pain or a burning
sensation, get medical attention
immediately.
Wear eye protection when charg-
ing or working near a battery.
Always provide ventilation when
working in an enclosed space.
o When lifting a plastic-cased battery, ex-
cessive pressure on the case may cause
battery acid to leak, resulting in personal
injury. Lift with a battery carrier or with
your hands on opposite corners.
o Never attempt to charge the battery when
the battery cables are connected.
o The electrical ignition system works with
high voltage.
Never touch these components with the
engine running or the ignition switched
on.

POWER STEERING FLUID LEVELG230A03A-AATThe 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.

Checking Condenser Cooling FanThe condenser coolant fan should come on
automatically whenever the air conditioning is in
operation.G220B01A-AATChecking Engine Cooling FanThe engine cooling fan should come on auto-
matically if the engine coolant temperature is
high.
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. Recommended Fluid
Use PSF-3 type fluidNOTE:Do not start the engine when the power
steering oil reservoir is empty.

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 vehicle at a distance of 118
in. (3m) 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).
4. Clean the head light lenses and turn on the
headlights.
5. Open the hood.
6. Draw the vertical line (through the center of
each headlight beam pattern) and the hori-
zontal line (through the center of each head-
light beam pattern) on the aiming screen.
And then, draw the parallel line at 0.827 in. (21

7. Adjust each cut-off line of the low beam to the
parallel line with a phillips screwdriver -

light bulbs so they may be changed. Be sure to
replace the burned-out bulb with one of the
same number and wattage rating.
See page 6-38 for the wattage description.
CAUTION:
Keep the lamps out of contact with petro-
leum products, such as oil, gasoline, etc.

EMISSION CONTROL SYSTEMS2
EMISSION CONTROL SYSTEM
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.
H010B01A-AAT1. Crankcase Emission Control
SystemThe Positive Crankcase Ventilation System is
employed to prevent air pollution caused by
blow-by gases being emitted from the crank-
case. This system supplies fresh filtered air to
the crankcase through the air intake hose.
Inside the crankcase, the fresh air mixes with
blow-by gases, which then pass through the
PCV valve and into the induction system.
H010A02GK-AATYour Hyundai is equipped with an emission
control system to meet all requirements of the
U.S. Environmental Protection Agency or Cali-
fornia Air Resources Board.
There are three emission control systems which
are as follows.
1) Crankcase Emission Control System
2) Evaporative Emission Control System
3) Exhaust Emission Control System
In order to ensure the proper function of the
emission control systems, it is recommended
that you have your car inspected and main-
tained by an authorized Hyundai dealer in ac-
cordance with the maintenance schedule in this
manual.
Caution for the Inspection and Maintenance
Test (Vehicle with Electronic Stability Pro-
gram)
o To prevent the vehicle from misfiring
during dynamometer testing, discon-
nect the ABS connector located inside
of the wheel guard (driver side).
o For more information, see shop manual
(BR Group, Wheel Speed Sensor).
CanisterFuel vapors generated inside the fuel tank are
absorbed and stored in the onboard canister.
When the engine is running, the fuel vapors
absorbed in the canister are drawn into the
induction system through the purge control
solenoid valve.Purge Control Solenoid Valve (PCSV)The purge control solenoid valve is controlled
by the Engine Control Module (ECM); when the
engine coolant temperature is low during idling,
the PCSV closes so that evaporated fuel is not
taken into the engine. After the engine warms-
up during ordinary driving, the PCSV opens to
introduce evaporated fuel to the engine.
H010C01S-AAT2. Evaporative Emission Control (Includ-
ing ORVR: Onboard Refueling Vapor
Recovery) SystemThe Evaporative Emission Control System is
designed to prevent fuel vapors from escaping
into the atmosphere.
(The ORVR system is designed to allow the
vapors from the fuel tank to be loaded into a
canister while refueling at the gas station, pre-
venting the escape of fuel vapors into the
atmosphere.)
