10. Replace the reservoir cap and check to
be sure the drain cock and the radiator
cap are fully closed and not leaking.
CAUTION:
Recheck after a few days and add the
coolant if the level is below the "L" level.
WARNING:
The cooling fan is controlled by engine
coolant temperature and may
sometimes operate 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 engine
coolant temperature decreases, the fan
will automatically shut off. This is a
normal condition.
CAUTION:
o Operating your vehicle without using
a proper air cleaner filter in place can
result in excessive engine wear.
o When removing the air cleaner filter,
be careful that dust or dirt does not
enter the air intake. These may result
in damage to the air cleaner filter.
!
CHANGING THE AIR
CLEANER FILTERG070A03Y-AATThe replacement of the air cleaner filter is
performed in the following manner.
1. Unsnap the clips around the cover.
2. When this is done, the cover can be
lifted off, the old filter removed and the
new filter put in its place.
Genuine Hyundai replacement parts are
recommended.

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.
!
G120E02A-AATAdding Brake Fluid
WARNING:Handle brake fluid carefully. It can dam-
age your vision if it gets into your eyes.
Use only DOT 3 or DOT 4 specification
fluid from a sealed container. Do not
allow the fluid can or reservoir to remain
open any longer than required. This will
prevent entry of dirt and moisture which
can damage the brake system and cause
improper operation.
To add brake fluid, first wipe away any dirt,
then unscrew the fluid reservoir cap. Slowly
pour the recommended fluid into the res-
ervoir. Do not overfill. Carefully replace the
cap on the reservoir and tighten.
AIR CONDITIONING CARE!
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 efficiency. When
removing such accumulations, brush or
hose them away carefully to avoid bending
the cooling fans.G140B01A-AATChecking the Air Conditioning Op-
eration1. 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 re-
frigerant level may damage the
compressor.

G240A01A-AATPOWER STEERING HOSESIt is suggested that you check the power
steering 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 crack-
ing, pulling, scuffing or worn spots.
Deterioration of the hose could cause
premature failure.
POWER STEERING FLUID
LEVELG230A01NF-AAT
Recommended FluidUse PSF-4 type fluidNOTE:Do not start the engine when the power
steering oil reservoir is empty.
ONF078007
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 characteristic in
extremely cold conditions.
CHECKING ELECTRIC COOLING
FANS!

WARNING:
The cooling fan is controlled by engine
coolant 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 engine
coolant temperature decreases the fan
will automatically shut off. This is a
normal condition.G220B01NF-GATChecking Engine Cooling FanThe engine cooling fan should come on
automatically if the engine coolant
temperature is high or whenever the air
conditioning is in operation.

The next paragraph shows how to reach
the 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 6-35 for the wattage descrip-
tions.
!
CAUTION:
o Keep the lights out of contact with
petroleum products, such as oil,
gasoline, etc.
o Be sure to replace the LED type
equipped bulbs with an assembly.
o After heavy, driving rain or washing,
headlight and taillight lenses could
appear frosty. This condition is
caused by the temperature difference
between the lamp inside and outside.
This is similar to the condensation on
your windows inside your vehicle
during the rain and doesn’t indicate a
problem with your vehicle. If the water
leaks into the lamp bulb circuitry, have
the vehicle checked by an Authorized
Hyundai Dealer.

CATALYTIC CONVERTERH020A01A-AAT(If Installed)Hyundai vehicle is equipped with a mono-
lith type three-way catalytic converter to
reduce the carbon monoxide, hydrocar-
bons 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
WARNING:
o Use unleaded fuel only.
o Maintain the engine in good operating
condition. Extremely high catalytic
converter temperatures can result
from improper operation of the
electrical, ignition 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 create 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 cata-
lytic converter or any other part of the
exhaust system.
H020A01NF
o Remember that your Hyundai dealer
is your best source of assistance.
o Do not stop your Hyundai over any
combustible material such as grass,
paper, leaves or rags. These materials
might contact the hot catalytic
converter and a fire might result.
