!
G020D01TG-GATImproper or incomplete service may re-
sult in problems. This section gives in-
structions only for the maintenance items
that are easy to perform.
Several procedures should be done by
an authorized Hyundai dealer.
NOTE:
Improper owner maintenance during the
warranty period may affect warranty
coverage.WARNING:
o Performing maintenance work on a
vehicle can be dangerous. You can
be seriously injured while perform-
ing some maintenance procedures.
If you lack sufficient knowledge and
experience or the proper tools and
equipment to do the work, have it
done by an authorized Hyundai
dealer.
o Working under the hood with the en-
gine running is dangerous. It be-
comes even more dangerous when
you wear jewelry or loose clothing.
These can become entangled in
moving parts and result in injury.
Therefore, if you must run the engine
while working under the hood, make
certain that you remove all jewelry
(especially rings, bracelets, watches,
and necklaces) and all neckties,
scarves, and similar loose clothing
before getting near the engine or
cooling fans.

CHECKING AND CHANGING
THE ENGINE COOLANT!
G050A01TG-AAT
WARNING:
Do not remove the radiator cap when
the engine is hot. When the engine is
hot, the engine coolant is under pres-
sure and may erupt through the open-
ing if the cap is removed. You could be
seriously burned if you do not observe
this precaution. Do not remove the ra-
diator cap until the radiator is cool to
the touch.
NOTE:
It is recommended that the engine cool-
ant should be changed by an authorized
Hyundai dealer.
G050B01A-AATRecommended Engine CoolantWhen adding coolant, use only deion-
ized water or soft water for your vehicle
and never mix hard water in the coolant
filled at the factory. An improper coolant
mixture can result in serious malfunction
or engine damage.
G050C01TG-AATTo Check the Coolant LevelThe coolant level can be seen on the side
of the plastic coolant reservoir. The level
of the coolant should be between the "L"
and "F" lines on the reservoir when the
engine is cool.

Use a high quality ethylene-glycol cool-
ant in a 50/50 mix with water. The engine
coolant should be compatible with alumi-
num engine parts. Additional corrosion
inhibitors or additives should not be used.
The cooling system must be maintained
with the correct concentration and type of
engine coolant to prevent freezing and
corrosion.
Never allow the concentration of anti-
freeze to exceed the 60% level or go
below the 35% level or damage to the
coolant system may result. For proper
concentration when adding or replacing
the coolant, refer to the following table.

G070A03Y-AATThe replacement of 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.CHANGING THE AIR

!
WARNING:
The cooling fan is controlled by engine
coolant temperature and may some-
times 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 cool-
ant temperature decreases, the fan will
automatically shut off. This is a normal
condition. CAUTION:
o Engine coolant can damage the fin-
ish of your car. If you spill engine
coolant on the car, wash it off thor-
oughly with clean water.
o The engine in your vehicle has alumi-
num engine parts and must be pro-
tected by an ethylene-glycol base
coolant to prevent corrosion and
freezing.
Do not use hard water. Hard water
can cause engine damage from cor-
rosion, overheating or freezing.
!
CAUTION:
o Operating your vehicle without a
proper air 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 re-
sult in damage to the air cleaner
filter.
!
If the level is below the "L" mark, add
engine coolant to bring it up between "L"
and "F". If the level is low, inspect for
coolant leaks and recheck the fluid level
frequently. If the level drops again, visit
your Hyundai dealer for an inspection
and diagnosis of the reason.

CHECKING THE BRAKES!
G120A01A-AAT
G120B01A-AATChecking the Brake Fluid Level
CAUTION:
Because brakes are essential to the
safe operation of the car, it is sug-
gested that they be checked and in-
spected by your Hyundai dealer. The
brakes should be checked and in-
spected for wear at those intervals
specified in the vehicle maintenance
schedule in Section 5.
!
WARNING:
Use caution when handling brake fluid.
It can damage your vision if it gets into
your eyes. It will also damage your
vehicle's paint if spilled on it and not
removed immediately.
!
WARNING:
The cooling fan is controlled by the
engine coolant temperature and may
sometimes operate even when the en-
gine is not running. Use extreme cau-
tion 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.
G120D01A-AATTo Check the Fluid LevelThe fluid level in the brake fluid reservoir
should be checked periodically. The level
should be between the "MIN" and "MAX"
marks on the side of the reservoir. If the
level is at or below the "MIN" mark, care-
fully add fluid to bring it up to "MAX". Do
not overfill.

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 re-
main open any longer than required.
This will avoid 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 reservoir. Do not overfill. Carefully
replace the cap on the reservoir and
tighten.
AIR CONDITIONER CAREG140A01A-AATKeeping the Condenser CleanThe air conditioner condenser (and en-
gine radiator) should be checked periodi-
cally for accumulation of dirt, dead in-
sects, leaves, etc. These can interfere
with maximum cooling efficiency. When
removing such accumulations, brush or
hose them away carefully to avoid bend-
ing the cooling fans.
Checking the amount of air condi-
tioner refrigerant and compressor
lubricantWhen the amount of refrigerant is low, the
performance of the air conditioning is
reduced. Overfilling also has a negative
impact on the air conditioning system.
Therefore, if abnormal operation is found,
have the system inspected by an autho-
rized HYUNDAI dealer.
NOTE:
It is important when servicing the air
conditioning system that the correct
type and amount of oil and refrigerant is
used. Otherwise, damage to the com-
pressor and abnormal system opera-
tion may occur.

CAUTION:
An open fuse indicates that there is a
problem in the electrical circuit. If you
replace a fuse and it blows as soon as
the accessory is turned on, the prob-
lem is serious and should be referred to
a Hyundai dealer for diagnosis and re-
pair. Never replace a fuse with anything
except a fuse with the same or a lower
amperage rating. A higher capacity fuse
could cause damage and create a fire
hazard.
!
NOTE:
See page 6-30 for the fuse panel de-
scriptions.
