Features of your vehicle

When the door is open, or if the engine is
not started within 1 minute, the tachome-
ter pointer may move slightly in ON posi-
tion with the engine OFF. This movement
is normal and will not affect the accuracy
of the tachometer once the engine is run-
ning.
D150203AUN
Engine temperature gauge
This gauge shows the temperature of the
engine coolant when the ignition switch
is ON.
Do not continue driving with an overheat-
ed engine. If your vehicle overheats, refer
to “If the engine overheats” in section 6.
OBH048051
CAUTION
If the gauge pointer moves beyond
the normal range area toward the
“H” position, it indicates overheat-
ing that may damage the engine.
CAUTION
Do not operate the engine within
the tachometer's RED ZONE.
This may cause severe engine dam-
age.
WARNING
Never remove the radiator cap
when the engine is hot. The engine
coolant is under pressure and
could cause severe burns. Wait
until the engine is cool before
adding coolant to the reservoir.

IF THE ENGINE OVERHEATS
F050000ABH
If your temperature gauge indicates over-
heating, you experience a loss of power,
or hear loud pinging or knocking, the
engine is probably too hot. If this hap-
pens, you should:
1. Pull off the road and stop as soon as it
is safe to do so.
2. Place the shift lever in P 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 con-
ditioning had been in use, it is normal
for cold water to be draining from it
when you stop.)
5. If the water pump drive belt is broken
or engine coolant is leaking out, stop
the engine immediately and call the
nearest authorized HYUNDAI dealer
for assistance.6. If you cannot find the cause of the
overheating, wait until the engine tem-
perature has returned to normal. Then,
if coolant has been lost, carefully add
coolant to the reservoir to bring the
fluid level in the reservoir up to the
halfway mark.
7. Proceed with caution, keeping alert for
further signs of overheating. If over-
heating happens again, call an author-
ized HYUNDAI dealer for assistance.
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.CAUTION
Serious loss of coolant indicates
there is a leak in the cooling system
and this should be checked as soon
as possible by an authorized
HYUNDAI dealer.
WARNING
Do not remove the radiator cap
when the engine is hot. This may
result in coolant being blown out of
the opening and cause serious
burns.

ENGINE OIL
G060100AEN-EU
Checking the engine oil level
1. Be sure the vehicle is on level ground.
2. Start the engine and allow it to reach
normal operating temperature.3. Turn the engine off and wait for a few
minutes (about 5 minutes) for the oil to
return to the oil pan.
4. Pull the dipstick out, wipe it clean, and
re-insert it fully.
5. Pull the dipstick out again and check
the level. The level should be between
F and L.
If it is near or at L, add enough oil to bring
the level to F.Do not overfill.
Use a funnel to help prevent oil from
being spilled on engine components.
Use only the specified engine oil. (Refer
to “Recommended lubricants and capaci-
ties” in section 8.)
WARNING - Radiator hose
Be very careful not to touch the
radiator hose when checking or
adding the engine oil as it may be
hot enough to burn you.
CAUTION
Do not overfill with engine oil.
Engine damage may result.

Changing the engine oil and filter
Have engine oil and filter changed by an
authorized HYUNDAI dealer according to
the Maintenance Schedule at the begin-
ning of this section.

The high-pressure cooling system has a
reservoir filled with year-round antifreeze
coolant. The reservoir is filled at the fac-
tory.
Check the antifreeze protection and
coolant level at least once a year, at the
beginning of the winter season, and
before traveling to a colder climate.

WARNING- Removing
radiator cap
Never attempt to remove the radi-
ator cap while the engine is oper-
ating or hot. Doing so might lead
to cooling system and engine
damage and could result in seri-
ous personal injury from escap-
ing hot coolant or steam.
(Continued)
(Continued)
Turn the engine off and wait until
it cools down. Use extreme care
when removing the radiator cap.
Wrap a thick towel around it, and
turn it counterclockwise slowly to
the first stop. Step back while the
pressure is released from the
cooling system. When you are
sure all the pressure has been
released, press down on the cap,
using a thick towel, and continue
turning counterclockwise to
remove it.
Even if the engine is not operat-
ing, do not remove the radiator
cap or the drain plug while the
engine and radiator are hot. Hot
coolant and steam may still blow
out under pressure, causing seri-
ous injury.
CALIFORNIA PROPOSI-
TION 65 WARNING
Engine oil contains chemicals
known to the State of California to
cause cancer, birth defects and
reproductive harm. Used engine oil
may cause irritation or cancer of
the skin if left in contact with the
skin for prolonged periods of time.
Always protect your skin by wash-
ing your hands thoroughly with
soap and warm water as soon as
possible after handling used oil.
