G140B01A-AATChecking the Air Conditioning Opera-
tion
1. 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 refriger-
ant level may damage the compressor.
G140C01A-AAT
LubricationTo 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.
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. accumulation of dirt, dead insects, leaves, etc.
These can interfere with maximum cooling effi-
ciency. When removing such accumulations,
brush or hose them away carefully to avoid
bending the cooling fins.

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 vehicle’s paint
if spilled on it and not removed immediately.

Keeping the Condenser Clean
The air conditioning condenser (and engine
radiator) should be checked periodically for
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 always between the "MAX" and "MIN" level
markings on the fluid reservoir. Fill as required.

FUSES
Replacing a Fusible Link
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 re-
placed, the new belt should be adjusted again
after two or three weeks to eliminate slack
resulting from initial stretching after use.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.
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.

FANS
WARNING:
The cooling fan is controlled by engine cool-
ant temperature and may sometimes oper-
ate even when the engine is not running.
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 en-
gine coolant temperature decreases the fan
will automatically shut off. This is a normal
condition.
G210A01A-AATCHECKING THE BATTERY
WARNING:
Batteries can be dangerous! When working
with batteries, carefully observe the follow-
ing precautions to avoid serious injuries.
The fluid in the battery contains a strong solu-
tion of sulfuric acid, which is poisonous and
highly corrosive. Be careful not to spill it on
yourself or the car. If you do spill battery fluid on
yourself, immediately do the following:
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 observe
these warnings to prevent injuries from occur-

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

EMISSION CONTROL SYSTEMS
7-1
7. EMISSION CON-
TROL SYSTEMSH010B01A-AAT1. Crankcase Emission Control
System
The 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.
H010C01S-AAT2. Evaporative Emission Control (In-
cluding ORVR: Onboard Refueling
Vapor Recovery) System
The 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,
preventing the escape of fuel vapors into
the atmosphere.)
Canister
Fuel 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 so-
lenoid 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.
H010D01A-AAT
3. Exhaust Emission Control System
The Exhaust Emission Control System is a
highly effective system which controls exhaust
emissions while maintaining good vehicle per-
formance.
H010A01GK-AAT
EMISSION CONTROL SYSTEM
Your 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 Inspection and Maintenance Test
(Vehicle with Traction Control System)
o To prevent the vehicle from misfiring
during dynamometer testing, disconnect
the ABS connector located inside of the
wheel guard (driver side).
o For more information, see shop manual
(BR Group, Wheel Speed Sensor).

EMISSION CONTROL SYSTEMS
All Hyundai vehicles are equipped with one or
two monolith type three-way catalytic convert-
ers to reduce the carbon monoxide, hydrocar-
bons and nitrogen oxides contained in the ex-
haust 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:
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 injection.
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.o Do not touch the catalytic converter or
any other part of the exhaust system
while the catalytic converter is hot. Shut
off the engine, wait for at least one hour
before touching the catalytic converter
or any other part of the exhaust system.
o Remember that your Hyundai dealer is
your best source of assistance.
o Do not stop your Hyundai over any com-
bustible material such as grass, paper,
leaves or rags. These materials might
contact the hot catalytic converter and a
fire might result.
