2- 2 DRIVING YOUR HYUNDAI
!WARNING: ENGINE EXHAUST CAN BE DANGEROUS!
C010A03A-AATEngine exhaust fumes can be extremely dangerous. If, at any time, you smell exhaust fumes inside the vehicle, open the windows immediately.
o Do not inhale exhaust fumes.
Exhaust fumes contain carbon monoxide, a colorless, odorless gas that can cause unconsciousness and death by asphyxiation.
o Be sure the exhaust system does not leak.
The exhaust system should be checked whenever the vehicle is raised to change the oil or for any other purpose. If you hear a change
in the sound of the exhaust or if you drive over something that strikes the underneath side of the car, have the exhaust system checked
as soon as possible by your Hyundai dealer.
o Do not run the engine in an enclosed area.
Letting the engine idle in your garage, even with the garage door open, is a hazardous practice. Never run the engine in your garage any
longer than it takes to start the engine and back the car out.
o Avoid idling the engine for prolonged periods with people inside the car.
If it is necessary to idle the engine for a prolonged period with people inside the car, be sure to do so only in an open area with the air intake
set at "Fresh" and fan operating at one of the higher speeds so fresh air is drawn into the interior.
If you must drive with the trunk lid/ tail gate open because you are carrying objects that make this necessary:
1. Close all windows.
2. Open side vents.
3. Set the air intake control at "Fresh", the air flow control at "Floor" or "Face" and the fan at one of the higher speeds.
To assure proper operation of the ventilation system, be sure the ventilation air intakes located just in front of the windshield are kept clear
of snow, ice, leaves or other obstructions.
!PROPOSITION 65 WARNING:Engine exhaust and a wide variety of automobile components and parts, including components found in the interior furnishings
in a vehicle, contain or emit chemicals known to the State of California to cause cancer and birth defects and reproductive harm.
In addition, certain fluids contained in vehicles and certain products of component wear contain or emit chemicals known to
the State of California to cause cancer and birth defects or other reproductive harm.

2- 18 DRIVING YOUR HYUNDAI
CAUTION:If overheating should occur when towing,
(the temperature gauge reads near red zone),
taking the following action may reduce or
eliminate the problem.
1. Turn off the air conditioner.
2. Reduce highway speed.
3. Select a lower gear when going uphill.
4. While in stop and go traffic, place the
gear selector in park or neutral and idle
the engine at a higher speed.

C190F01S-AATTrailer or Vehicle Towing Tips
1. Before towing, check hitch and safety chain
connections as well as proper operation of
the trailer running lights, brake lights, and
turn signals.
2. Always drive your vehicle at a moderate
speed (Less than 60 mph)
3. Trailer towing requires more fuel than normal
conditions.
4. To maintain engine braking efficiency and
electrical charging performance, do not use
fifth gear (manual transaxle) or overdrive
(automatic transaxle).
5. Always secure items in the trailer to prevent
load shift while driving.
6. Check the condition and air pressure of all
tires on the trailer and your car. Low tire
pressure can seriously affect the handling.
Also check the spare tire.
7. The vehicle/trailer combination is more af-
fected by crosswind and buffeting.
When being passed by a large vehicle, keep
a constant speed and steer straight ahead.
If there is too much wind buffeting slow down
to get out of the other vehicle's air turbulence.
8. When parking your car and trailer, especially
on a hill, be sure to follow all the normal
precautions. Turn your front wheel into the
curb, set the parking brake firmly, and put the
transaxle in 1st or Reverse (manual) or Park
(automatic). In addition, place wheel chocks
at each of the trailer's tires.9. If the trailer has electric brakes, start your
vehicle and trailer moving, and then apply the
trailer brake controller by hand to be sure the
brakes are working. This lets you check
your electrical connection at the same time.
10.During your trip, check occasionally to be
sure that the load is secure, and that the
lights and any trailer brakes are still working.
11.Avoid jerky starts, sudden acceleration or
sudden stops.
12.Avoid sharp turns and rapid lane changes.
13.Avoid holding the brake pedal down too long
or too frequently. This could cause the brakes
to overheat, resulting in reduced braking
efficiency.
14.When going down a hill, shift into a lower gear
and use the engine braking effect.
When ascending a long grade, downshift the
transaxle to a lower gear and reduce speed
to reduce chances of engine overloading
and/or overheating.
15.If you have to stop while going uphill, do not
hold the vehicle in place by pressing on the
accelerator. This can cause the automatic
transaxle to overheat. Use the parking brake
or footbrake.
NOTE:When towing check transaxle fluid more
frequently.

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.
5. Start the engine, top off the radiator with
water and then add coolant to the reservoir
until the level is between "L" and "F".
6. Replace the radiator and reservoir caps and
check to be sure the drain cocks are fully
closed and not leaking.G060A02Y-AATSPARK PLUGS
Your engine was originally equipped with plati-
num-tipped spark plugs.
Platinum-tipped spark plugs will last longer than
conventional type spark plugs and can be
identified by blue lines on the ceramic shell.
NOTE:Do not clean or regap platinum-tipped spark
plugs.
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.
HSM392G060B04Y-AAT
Replacing the Spark PlugsThe spark plugs should be changed at the
intervals specified in the vehicle maintenance
schedule in Section 5 or whenever engine
performance indicates they should be changed.
Symptoms that suggest poor spark plug perfor-
mance include engine misfiring under load, loss
of fuel economy, poor acceleration, etc. When
spark plugs are replaced, always use spark
plugs recommended by Hyundai. The use of
other spark plugs can result in loss of perfor-
mance, radio interference or engine damage.
NOTE:When replacing the spark plugs, always use
the genuine parts recommended.

G060C04Y-AATChanging the Spark Plugs
You will find it easier to change spark plugs if the
engine is cold. Always change one spark plug
at a time. This helps avoid getting the wires
mixed up.
1. Remove the center (2.4 L) cover on the
engine rocker cover.
NOTE:It is recommended that the spark plugs (For
2.7L Engines) should be changed by an
authorized Hyundai dealer.
2. Using a clean cloth, remove any dirt that has
accumulated around the base of the spark
plug so it cannot fall into the cylinder when the
spark plug is removed.3. To remove the spark plug cable, pull straight
up on the insulated connector, not the cable.
Pulling on the cable may damage the carbon
core conductor.
WARNING:It is recommended that the engine be cool
or cold when changing the spark plugs. If
the engine is hot, you could burn yourself
on the insulated connector, the spark plug
or the engine itself.
4. When preparing to remove the old spark
plug, guide the socket down over the spark
plug, being careful not to damage the ce-
ramic insulator.
5. To remove the old spark plug, turn the
wrench handle in a counterclockwise direc-
tion.6. To install the new spark plug, guide the
socket down over the spark plug, being
careful not to damage the ceramic insulator.
NOTE:Spark plugs should be tightened to speci-
fication. Over-tightening can damage the
threads in the aluminum cylinder head.
Also, leaving them too loose can cause the
spark plug to get very hot and possibly
result in damage to the engine.
7. Replace the cable by pushing the insulated
connector directly down onto the electrode.
Check to be sure it has snapped into place
and can’t fall off.

FREE-PLAYG140D01A-AATChecking the Compressor Drive Belt
G140C01A-AATLubrication
To 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.
G140B01A-AATChecking the Air Conditioning Opera-
tion
1. 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 refrig-
erant level may damage the compressor.
!
When the air conditioning is being used regu-
larly, the compressor drive belt tension should
be checked at least once a month with the
engine turned off.
To check the drive belt tension, press down on
the belt halfway between the engine crankshaft
and compressor pulleys. Pressing with your
finger, you should not be able to deflect this belt
anymore than 1/3 of an inch. If you have the
instruments to check it, with a force of 22 lb.
(98N), the deflection should be 0.315 inches
(approx 8.0 mm). If the belt is too loose, have it
adjusted by your Hyundai dealer.To check the steering wheel free-play, stop the
car with the wheels pointed straight ahead and
gently move the steering wheel back and forth.
Use very light finger pressure and be sensitive
to changes in resistance that mark the limits of
the free-play. If the free-play is greater than
specified, have it inspected by your Hyundai
dealer and adjusted or repaired if necessary.
