2004 Hyundai Elantra stop start

3WHAT TO DO IN AN EMERGENCY
4IF 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.
D030A01A-AAT
If your temperature gauge indicates overheat-
ing, you experience a loss of power, or hear loud
pinging or knocking and the engine is probably
too hot. If this happens and, 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
engine 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 engine coolant leak-
ing 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). post or cable of the booster battery. Then
attach the other end of that cable to a solid
metal part of the engine away from the
battery. Do not connect the cable to any
moving part.
4. Start the engine in the car with the booster
battery and let it run for a few minutes. This
will help to assure that the booster battery is
fully charged. During the jumping operation,
run the engine in this vehicle at about 2,000
rpm.
5. Start the engine in the car with the dis-
charged battery using the normal starting
procedure. After the engine starts, leave the
jumper cables connected and let the engine
run at fast idle or about 2,000 rpm for several
minutes.
6. Carefully remove the jumper cables in the
reverse order of attachment.
If you do not know why your battery became
discharged (because the lights were left on,
etc.), have the charging system checked by
your Hyundai dealer.

CHANGING THE OIL AND FILTER
!
If the oil level is close to or below the "LOW"
mark, add oil until it reaches the "FULL" 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 "FULL" and "LOW"
marks is equal to about 1 quart of oil.
G040A02E-AAT2. Open the hood and remove the engine oil
filler cap.
3. Slide underneath the car and loosen the
drain plug by turning it counterclockwise with
a wrench of the proper size. Be sure that a
drain pan is in position to catch the oil as it
drains out, then remove the drain plug.
WARNING:Be very careful when draining the engine oil
as it may be hot enough to burn you!
G030D01A-AAT
Adding 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). Set the parking
brake.4. When the oil has stopped draining, replace
the drain plug using a new washer and
retighten by turning it clockwise.
Drain plug tightening torque:
4.0 ~ 4.5 kgf.m
5. Remove the oil filter. You should be able to
unscrew the filter with your hands. (If your
hands are slippery, try to use a cloth be-
tween your hands and the filter to give
yourself a better grip.) A certain amount of oil
will come out when you remove the filter, so
be sure to have your drain pan in place
underneath it.
6. Install a new oil filter in accordance with the
instructions on the carton or on the filter itself.
Do not over-tighten.

To Change the Engine Coolant
The engine coolant should be changed at those
intervals specified in the vehicle maintenance
schedule in Section 5.
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.
2. 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.
3. 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. Start the engine, top off the radiator with
water and then add engine coolant to the
reservoir until the level is between "LOW"
and "FULL".
6. Replace the radiator and reservoir caps and
check to be sure the drain cocks are fully
closed and not leaking. 4. 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.
Now fill the radiator with clean demineralized
or distilled water. Continue to add clean
demineralized or distilled water in small quan-
tities until the fluid level stays up in the
radiator neck.

24POWER STEERING FLUID LEVEL
G230A03A-AAT
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 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.

G250A01A-AATFOR MORE INFORMATION ABOUT
YOUR HYUNDAI
If you desire additional information about main-
taining and servicing your Hyundai, you may
purchase a factory Shop Manual at your Hyundai
dealer's parts department. This is the same
manual used by dealership technicians and
while it is highly technical it can be useful in
obtaining a better understanding of your car and
how it works.
G240A01A-AATPOWER STEERING HOSES
It is suggested that you check the power steer-
ing hose connections for fluid leakage at regular
intervals. The power steering hoses should be
replaced if there is severe surface cracking,
scuffing or worn spots. Deterioration of the hose
could cause premature failure.
Recommended FluidUse PSF-3 type fluid
NOTE:Do not start the engine when the power
steering oil reservoir is empty.

DESCRIPTION

7EMISSION CONTROL SYSTEMS
3CATALYTIC CONVERTER
!!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 injec-
tion.
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.
H020A01S-AAT
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 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.
