C140A01A-AAT
You can save fuel and get more miles from your
car if you follow these suggestions:
o Drive smoothly. Accelerate at a moderate
rate. Don't make "jack-rabbit" starts or full-
throttle shifts and maintain a steady cruising
speed. Don't race between stoplights. Try to
adjust your speed to that of the other traffic
so you don't have to change speeds unnec-
essarily. Avoid heavy traffic whenever pos-
sible. Always maintain a safe distance from
other vehicles so you can avoid unneces-
sary braking. This also reduces brake wear.
o Drive at a moderate speed. The faster you
drive, the more fuel your car uses. Driving at
a moderate speed, especially on the high-
way, is one of the most effective ways to
reduce fuel consumption.
o Don't "ride" the brake or clutch pedal. This
can increase fuel consumption and also
increase wear on these components. In
addition, driving with your foot resting on the
brake pedal may cause the brakes to over-
heat, which reduces their effectiveness and
may lead to more serious consequences.
o Take care of your tires. Keep them inflated
to the recommended pressure. Incorrect
inflation, either too much or too little, results
in unnecessary tire wear. Check the tire
pressures at least once a month.

TCS ON/OFF Mode
When the TCS is running, the TCS indicator in
the instrument cluster will blink.
If you turn the system off by pressing the TCS
switch, the TCS-OFF indicator will come on and
stay on. In the TCS-OFF mode, the SLIP control
will be deactivated. Adjust you driving accord-
ingly. To turn the system back on, press the
switch again. The TCS-OFF indicator should go
off.
NOTE:1) The TCS mode will automatically be
turned ON after the engine is turned off
and restarted.
2) When the traction control system is
operating properly, you can feel a slight
pulsation in the vehicle. This is only the
effect of brake control and indicates
nothing unusual.
3) When the engine starts, a click is heard
from the engine compartment; however,
this is only the sound of traction control
being checked.
4) When moving out of the mud or fresh
snow, pressing the accelerator pedal
may not cause the engine speed to in-
crease due to TCS operation.
C310D01O-AAT
Indicators and Warning
The indicators should illuminate when the igni-
tion key is turned to ON or START but should
go out after three seconds.
If the indicators do not illuminate, or the TCS or
TCS-OFF indicator does not go out after 3
seconds, have it checked by an authorized
dealer.
Should there be any unusual conditions in the
device while driving, TCS-OFF indicator illumi-
nates as a warning.
If TCS-OFF indicator illuminates, pull your car
to a safe place and stop the engine.
Then, start the engine again to check if the TCS-
OFF indicator goes out.
If the indicator remains lit even after the engine
has been started, have your car checked by an
authorized Hyundai dealer.
NOTE:1) When the TCS-OFF indicator illuminates,
traction control is automatically deacti-
vated for safety.
2) This warning function is not provided
when the driver selects the TCS-OFF
mode.

!WARNING:Improperly loading your car and trailer can
seriously affect its steering and braking
performance causing a crash which could
cause serious injury or death.
C190F01S-AAT
Trailer 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, occasionally check to be
sure that the load is secure, and that the
lights and any trailer brakes are still work-
ing.
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 over-
loading 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.
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.

o If you should accidentally get acid on your
skin or in your eyes, immediately remove
any contaminated clothing and flush the area
with clear water for at least 15 minutes. Then
promptly obtain medical attention. If you
must be transported to an emergency facil-
ity, continue to apply water to the affected
area with a sponge or cloth.
o The gas produced by the battery during the
jump-start operation is highly explosive. Do
not smoke or allow a spark or an open flame
in the vicinity.
o The battery being used to provide the jump
start must be 12-volt. If you cannot deter-
mine that it is a 12-volt battery, do not attempt
to use it for the jump start.
o To jump start a car with a discharged battery,
follow this procedure exactly:
1. If the booster battery is installed in another
vehicle, be sure the two vehicles are not
touching.
2. Turn off all unnecessary lights and acces-
sories in both vehicles.
3. Attach the clamps of the jumper cable in the
exact location shown in the illustration. First,
attach one clamp of the jumper cable to the
positive (+) post or cable of the discharged
battery. Then attach the other end of the
same cable to the positive (+) post or cable
of the booster battery. Next, using the other
cable, attach one clamp to the negative (-)D020A02A-AAT
WARNING:The gas produced by the battery during the
jump-start operation is highly explosive. If
these instructions are not followed exactly,
serious personal injury and damage to the
vehicle may occur! If you are not sure how
to follow this procedure, seek qualified
assistance. Automobile batteries contain
sulfuric acid. This is poisonous and highly
corrosive. When jump starting, wear pro-
tective glasses and be careful not to get
acid on yourself, your clothing or on the car.

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.

!WARNING:Wheel and wheel covers may have sharp
edges. Handle them carefully to avoid pos-
sible severe injury.
Before putting the wheel into place, be sure
that there is nothing on the hub or wheel
(such as mud, tar, gravel, etc.) that inter-
feres with the wheel from fitting solidly
against the hub. If there is, remove it. If there
is not good contact on the mounting sur-
face between the wheel and hub, the wheel
nuts could loosen and cause the loss of a
wheel. Loss of a wheel may result in loss of
control of the vehicle. This may cause seri-
ous injury or death.
D060G02E D060G02Y-AAT
6. Changing Wheels
Loosen the wheel nuts and remove them with
your fingers. Slide the wheel off the studs and
lay it flat so it cannot roll away. To put the wheel
on the hub, pick up the spare tire, line up the
holes with the studs and slide the wheel onto
them. If this is difficult, tip the wheel slightly and
get the top hole in the wheel lined up with the top
stud. Then jiggle the wheel back and forth until
the wheel can be slid over the other studs.
D060F02E-AAT
5. Raising the Car
After inserting a wrench bar into the wheel nut
wrench, install the wrench bar into the jack as
shown in the drawing. To raise the vehicle, turn
the wheel nut wrench clockwise. As the jack
begins to raise the vehicle, double check that it
is properly positioned and will not slip. If the jack
is on soft ground or sand, place a board, brick,
flat stone or other object under the base of the
jack to keep it from sinking.
Raise the car high enough so that the fully
inflated spare tire can be installed. To do this,
you will need more ground clearance than is
required to remove the flat tire.

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.

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. Oil filter tightening torque :
1.2 ~ 1.6 kgf.m
Be sure that the mounting surface on the
engine is clean and that the old gasket is
removed completely. Lubricate the new
gasket on the filter with clean engine oil
before installation.
7. Refill the crankcase with the recommended
engine oil. Refer to the specification in chap-
ter 9 for engine oil capacity.
8. Start the engine and check to be sure no oil
is leaking from the drain plug or oil filter.
9. Shut off the engine and recheck the oil level.
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 animals. Al-
ways protect your skin by washing your
hands thoroughly with soap and warm
water as soon as possible after handling

Replacing the Spark Plugs
The 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.

Changing 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 cover on the engine
rocker cover.
2. Using a clean cloth, remove any dirt that has
accumulated around 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.
HGK256
!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 spark plug, turn the wrench
handle in a counterclockwise direction.
6. To replace 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 firmly.
Over-tightening can damage the threads in
the aluminum cylinder head. Leaving them
too loose can cause the spark plugs 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.
