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 pressure and
may erupt through the opening if the cap
is removed. You could be seriously
burned if you do not observe this precau-
tion. Do not remove the radiator cap until
the radiator is cool to the touch.
!
NOTE:Always dispose of used engine oil in an
environmentally acceptable manner. It
is suggested that it be placed in a sealed
container and taken to a service station
for reclamation. Do not pour the oil on the
ground or put it into the household trash.
PROPOSITION 65 WARNING:
Used engine oil may cause irritation or
cancer of the skin if left in contact with
the skin for prolonged periods of time.
Used engine oil contains chemicals that
have caused cancer in laboratory ani-
mals. Always protect your skin by wash-
ing your hands thoroughly with soap and
warm water as soon as possible after
handling used oil.
!!
CAUTION:
Slowly pour the recommended oil into a
funnel. Do not overfill to avoid damage to
the engine.
WARNING:
Be very careful not to touch the radiator
hose when adding the engine oil as it may
be hot enough to burn you.
NOTE:It is recommended that the engine cool-
ant should be changed by an authorized
Hyundai dealer. 2. Add oil, then check the level again. Do
not overfill.
3. Replace the cap by turning it clockwise.
The distance between the "F" and "L" marks
is equal to about 1 quart of oil.

G050B01A-AATRecommended Engine CoolantUse a high quality ethylene-glycol coolant
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 antifreeze to exceed the 60% level or go
below the 35% level, or damage to the
cooling system may result. For proper con-
centration when adding or replacing the
engine coolant, refer to the following table.

G050C01TG-GATTo 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 warm with it at idle . If the level is below
the "L" mark, add engine coolant to bring
it up to "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.
G050C01TG
!
CAUTION:
o Engine coolant can damage the finish
of your car. If you spill engine coolant
on the car, wash it off thoroughly 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 freez-
ing.
Do not use hard water. Hard water can
cause engine damage from corro-
sion, overheating or freezing.
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 coolant
fan so that you are not injured by a
rotating fan blade. As the engine coolant
temperature decreases, the fan will au-
tomatically shut off. This is a normal
condition.

G110A01E-AATTransaxle fluid in the automatic transaxle
should be checked at those intervals speci-
fied in the vehicle maintenance schedule
in Section 5.NOTE:Automatic transaxle fluid is basically
red in color. As driving distance in-
creases, the fluid color turns darkish red
gradually. It is a normal condition and
you should not judge the need to replace
based upon the changing color.
You must replace the automatic
transaxle fluid in accordance with inter-
vals specified in the vehicle maintenance
schedule in section 5.
!
G110B05A-AATRecommended Fluid
Your Hyundai automatic transaxle is spe-
cially designed to operate with HYUNDAI
GENUINE ATF SP III, DIAMOND ATF SP III,
SK ATF SP III or other brands meeting the
SP III specification approved by Hyundai
Motor Co.. Damage caused by a
nonspecified fluid is not covered by your
new vehicle limited warranty.
CAUTION:
Use of aftermarket ATF additives may
cause damage to the automatic
transaxle.
Only use HYUNDAI GENUINE ATF SP III,
DIAMOND ATF SP III, SK ATF SP III or
other brands meeting the SP III specifi-
cation approved by Hyundai Motor Co..
If you are having your vehicle serviced
at a facility other than a Hyundai dealer,
verify that the correct ATF is used for
your vehicle.
CAUTION:
o Radiator antifreeze (engine coolant)
should not be used in the washer sys-
tem because it will damage the car's
finish.
o The washer lever should not be pulled
and the washer should not be oper-
ated if the washer reservoir is empty.
This can damage the washer fluid
pump.
!!
WARNING:
o Windshield washer fluid agents con-
tain some amounts of alcohol and can
be flammable under certain circum-
stances. Do not allow sparks or flame
to contact the washer fluid or the
washer fluid reservoir. Damage to
the vehicle or its occupants could
occur.
o Windshield washer fluid is poisonous
to humans and animals. Do not drink
windshield washer fluid. Serious in-
jury or death could occur.

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.
G110D02O-AATTo Check the Transaxle Fluid LevelPark the car on level ground with the park-
ing brake engaged. When the transaxle
fluid level is checked, the transaxle fluid
should be at normal operating tempera-
ture and the engine idling.
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 return to "N" or "P". With the
engine still idling:
1. Open the hood, being careful to keep
hands, long hair and clothing clear of
any moving parts.
!
G110C01TG-AATTransaxle Fluid CapacityThe fluid capacity of the automatic
transaxle is 11.52 U.S. quarts (10.9 liters).
WARNING:
The transaxle fluid level should be
checked when the engine is at normal
operating temperature. This means that
the engine, radiator, radiator hose, ex-
haust system etc., are very hot. Exer-
cise great care not to burn yourself dur-
ing this procedure.

CHECKING THE BRAKES!
G120B01A-AATChecking the Brake Fluid Level
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 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 coolant
temperature decreases, the fan will au-
tomatically shut off. This is a normal
condition.
Fluid level should be within "HOT" range
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
maintenance schedule in Section 5.
!
3. 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.
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.G120C02A-AATRecommended Brake FluidUse only hydraulic brake fluid conforming
to DOT 3 or DOT 4 specifications in your
braking system. Follow the instructions
printed on the container.

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 CAREG140A01A-AATKeeping the Condenser CleanThe air conditioning condenser (and en-
gine radiator) should be checked periodi-
cally for accumulation of dirt, dead insects,
leaves, etc. These can interfere with maxi-
mum cooling efficiency. When removing
such accumulations, brush or hose them
away carefully to avoid bending the cool-
ing 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 condi-
tioning 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:
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.
G200B01NF-AATReplacing Accessory Fuse
G200B01TG-A
The fuse box for the lights and other elec-
trical accessories will be found on the left
side of the instrument panel. Inside the box
you will find a list showing the circuits
protected by each fuse.
If any of your car's lights or other electrical
accessories stop working, a blown (open)
fuse could be the reason. If the fuse has
opened, you will see that the metal strip
inside the fuse has melted through. If you
suspect a blown fuse, follow this proce-
dure:
1. Turn off the ignition and all other
switches.
G200A01A-AATReplacing a Fusible LinkA fusible link will melt if the electrical cir-
cuits from the battery are ever overloaded,
thus preventing damage to the entire wir-
ing harness. (This could be caused by a
short in the system drawing too much cur-
rent.) 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 in the
engine compartment for easy inspection.

Good Open-Replace
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 problem is
serious and should be referred to a
Hyundai dealer for diagnosis and repair.
Never replace a fuse with anything ex-
cept 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 6-33 for the fuse panel descrip-
tions.
3. Be sure to check all other fuses even if
you find one that appears to have
opened.
G200B02NF
2. Open the fuse box and examine each
fuse. Remove each fuse by pulling it
toward you (a small "fuse puller" tool is
contained in the relay and fuse box of
the engine room to simplify this opera-
tion).4. Replace the blown fuse by pressing a
new fuse of the same rating into place.
The fuse should be a snug fit. If it is not,
have the fuse clip repaired or replaced
by a Hyundai dealer. If you do not have
a spare fuse, you may be able to borrow
a fuse of the same or lower rating from
an accessory you can temporarily get
along without (the radio or cigarette
lighter, for example). Always remember
to replace the borrowed fuse.

G230A01TG
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.

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 coolant
temperature decreases the fan will au-
tomatically shut off. This is a normal
condition.G220B01NF-GATChecking Engine Cooling FanThe engine cooling fan should come on
automatically if the engine coolant tem-
perature is high or whenever the air con-
ditioning is in operation.
G240A01A-AATPOWER STEERING HOSESIt is suggested that you check the power
steering hose connections for fluid leak-
age at those intervals specified in the ve-
hicle maintenance schedule in Section 5.
The power steering hoses should be re-
placed if there is severe surface cracking,
pulling, scuffing or worn spots. Deteriora-
tion of the hose could cause premature
failure.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.
Recommended FluidUse PSF-3 type fluidNOTE:Do not start the engine when the power
steering oil reservoir is empty.
