GAUGE
WARNING:Never remove the radiator cap when the
engine is hot. The engine coolant is under
pressure and could erupt and cause severe
burns. Wait until the engine is cool before
adding coolant to the reservoir.
B280A01A-AATFUEL GAUGEThe needle on the gauge indicates the approxi-
mate fuel level in the fuel tank. The fuel capacity
is given in Section 9.INSTRUMENT CLUSTER
HJM2182 HJM2181
The needle on the engine coolant temperature
gauge should stay in the normal range. If it moves
across the dial to "H" (HOT), pull over and stop as
soon as possible and turn off the engine. Then
open the hood and, after the engine has cooled,
check the coolant level and the water pump drive
belt. If you suspect cooling system trouble, have
your cooling system checked by a Hyundai dealer
as soon as possible.

34WHAT TO DO IN AN EMERGENCY
IF THE ENGINE OVERHEATS
!!
!
WARNING:
While the engine is running, keep hair,
hands and clothing away from moving parts
such as the fan and drive belts to prevent
injury.
5. If the water pump drive belt is broken or
engine coolant is leaking out, stop the engine
immediately and call the nearest Hyundai
dealer for assistance.
WARNING:
Do not remove the radiator cap when the
engine is hot. This can allow coolant to be
blown out of the opening and cause seri-
ous burns.6. If you cannot find the cause of the overheat-
ing, wait until the engine temperature has
returned to normal. Then, if coolant has been
lost, carefully add coolant to the reservoir
(page 6-9) to bring the fluid level in the
reservoir up to the halfway mark.
7. Proceed with caution, keeping alert for fur-
ther signs of overheating. If overheating
happens again, call a Hyundai dealer for
assistance.
CAUTION:
Serious loss of coolant indicates there is a
leak in the cooling system and this should
be checked as soon as possible by a Hyundai
dealer.
D030A02A-AATIf your temperature gauge indicates overheat-
ing, you experience a loss of power, or hear loud
pinging or knocking, the engine is probably too
hot. If this happens, you should:
1. Pull off the road and stop as soon as it is safe
to do so.
2. Place the gear selector lever in "P" (auto-
matic), or neutral (manual transaxle) and set
the parking brake. If the air conditioning is on,
turn it off.
3. If engine coolant is running out under the car
or steam is coming out from the hood, stop
the engine. Do not open the hood until the
coolant has stopped running or the steaming
has stopped. If there is no visible loss of
engine coolant and no steam, leave the
engine running and check to be sure the
engine cooling fan is operating. If the fan is
not running, turn the engine off.
4. Check to see if the water pump drive belt is
missing. If it is not missing, check to see that
it is tight. If the drive belt seems to be
satisfactory, check for coolant leaking from
the radiator, hoses or under the car. (If the
air conditioning had been in use, it is normal
for cold water to be draining from it when you
stop).

WARNING:
Be very careful not to touch the radiator
hose when adding the engine oil as it may
be hot enough to burn you.

CHANGING THE OIL AND FILTER
If the oil level is close to or below the "L" mark,
add oil until it reaches the "F" mark. To add oil:
1. Remove the oil filler cap by turning it counter-
clockwise.
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.The engine oil and filter should be changed at
those intervals specified in the maintenance
schedule in Section 5. If the car is being driven
in severe conditions, more frequent oil and filter
changes are required.
The procedure for changing the oil and filter is
as follows:
1. Park the car on level ground and set the
parking brake. Start the engine and let it
warm up until the needle on the coolant
temperature gauge moves above the lowest
mark. Turn the engine off and place the gear
selector lever in "P" (automatic) or reverse
gear (manual transaxle).G030D01JM-AATAdding 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 aluminum 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 concentration when
adding or replacing the engine coolant, refer to
the following table.

G050C01A-AATTo Check the Coolant LevelThe coolant level can be seen on the side of the
plastic coolant reservoir. The level of the cool-
ant should be between the "L" and "F" lines on
the reservoir when the engine is cool. 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 AND CHANGING THE
ENGINE COOLANT!
G050A01A-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 precaution. Do not
remove the radiator cap until the radiator is
cool to the touch.

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. 2. Turn the radiator cap counterclockwise with-
out pressing down on it, until it stops. This
relieves any pressure remaining in the cool-
ing system. And remove the radiator cap by
pushing down and turning counterclock-
wise.
3. Be sure your drain receptacle is in place.
Open the drain cock on the radiator. Allow all
the engine coolant to drain from the cooling
system, then securely close the drain cock.
4. Check Section 9 for the capacity of the
cooling system in your car. Then, following
the manufacturer's directions on the engine
coolant container, add the appropriate quan-
tity of coolant to the radiator.
5. Fill the radiator with clean demineralized or
distilled water. Continue to add clean dem-
ineralized or distilled water in small quantities
until the fluid level stays up in the radiator
neck.6. Start the engine, top off the radiator with
water and then add coolant to the reservoir
until the level is between "L" and "F".
7. Replace the radiator and reservoir caps and
check to be sure the drain cocks are fully
closed and not leaking.
G050D02A-AATTo Change the Engine CoolantThe engine coolant should be changed at those
intervals specified in the vehicle maintenance
schedule in Section 5.
HJM5034G050D01JM
CAUTION:
Engine coolant can damage the finish of
your car. If you spill engine coolant on the
car, wash it off thoroughly with clean water.
1. Park the car on level ground, set the park-
ing brake and remove the radiator cap when
cool.

FILLING THE WASHER RESERVOIRG090A02JM-AATThe washer fluid reservoir supplies fluid to the
front and rear washer systems.
A good quality washer fluid should be used to fill
the washer reservoir. The fluid level should be
checked more frequently during inclement
weather or whenever the washer system is in
more frequent use.
The capacity of the washer reservoir is 3.59
U.S. quarts (3.4 Liters).
CAUTION:
o Radiator anti-freeze (engine coolant)
should not be used in the washer system
because it will damage the car's finish.
o The washer should not be operated if the
washer reservoir is empty. This can dam-
age the washer fluid pump.
!!
WARNING:
o Windshield washer fluid agents contain
some amounts of alcohol and can be
flammable under certain circumstances.
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 wind-
shield washer fluid. Serious injury or
death could occur.

G110D02O-AATTo Check the Transaxle Fluid LevelPark the car on level ground with the parking
brake engaged. When the transaxle fluid level
is checked, the transaxle fluid should be at
normal operating temperature 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.
G110C01JM-AATTransaxle Fluid CapacityThe fluid capacity of the automatic transaxle is
8.2 U.S. quarts (7.8 liters).
WARNING:
The transaxle fluid level should be checked
when the engine is at normal operating
temperature. This means that the engine,
radiator, exhaust system etc., are very hot
so you should exercise great care not to
burn yourself during this procedure.

G130B02A-AATTo Replace the FluidRecommended 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 imme-
diately.
AIR CONDITIONING CAREG140A01A-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 ef-
ficiency. When removing such accumulations,
brush or hose them away carefully to avoid
bending the cooling fans.
HJM5007
CHECKING THE CLUTCH FLUIDG130A01A-AATTo Check the Clutch FluidThe 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.
Fluid loss indicates a leak in the clutch system
which should be inspected and repaired imme-
diately. Consult your Hyundai dealer.
