Features of your vehicle
Opening the fuel filler door
The fuel filler door must be opened from
inside the vehicle by pulling up the fuel
filler door opener lever.
✽✽NOTICE
If the fuel filler door does not open
because ice has formed around it, tap
lightly or push on the door to break the
ice and release the door. Do not pry on
the door. If necessary, spray around the
door with an approved de-icer fluid (do
not use radiator anti-freeze) or move the
vehicle to a warm place and allow the ice
to melt.
1. Stop the engine.
2. To open the fuel filler door, pull the fuel filler door opener up.
3. Pull the fuel filler door (1) out to fully open.
4. To remove the cap, turn the fuel filler cap (2) counterclockwise.
5. Refuel as needed.
Closing the fuel filler door
1. To install the cap, turn it clockwise until it “clicks” one time. This indicates that the cap is securely tightened.
2. Close the fuel filler door and push it lightly making sure that it is securely closed.

WARNING - Refueling
If pressurized fuel sprays out, it
can cover your clothes or skin
and thus subject you to the risk
of fire and burns. Always remove
the fuel cap carefully and slowly.
If the cap is venting fuel or if you
hear a hissing sound, wait until
the condition stops before com-
pletely removing the cap.
Do not "top off" after the nozzle automatically shuts off whenrefueling.
Tighten the cap until it clicks one time, otherwise the Check Engine light will illuminate.
Always check that the fuel cap is installed securely to prevent fuel
spillage in the event of an acci- dent.

Features of your vehicle
Engine temperature gauge
This gauge shows the temperature of the
engine coolant when the ignition switchis ON.
Do not continue driving with an overheat-
ed engine. If your vehicle overheats, refer
to “If the engine overheats” in section 6.
CAUTION
If the gauge pointer moves beyondthe normal range area toward the
“H” position, it indicates overheat-ing that may damage the engine.
CAUTION
Do not operate the engine withinthe tachometer's RED ZONE.
This may cause severe engine dam-age.WARNING
Never remove the radiator cap
when the engine is hot. The enginecoolant is under pressure and
could cause severe burns. Wait
until the engine is cool before
adding coolant to the reservoir.

What to do in an emergency

IF THE ENGINE OVERHEATS
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 (automatic transaxle) or neutral (manual transaxle)
and set the parking brake. If the air con-
ditioning is on, turn it off.
3. If engine coolant is running out under the vehicle 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 operat-
ing. 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 vehicle. (If the air
conditioning had been in use, it is nor-
mal 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 systemand this should be checked as soon
as possible by an authorizedHYUNDAI dealer.
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 serious burns.

ENGINE OIL
Checking the engine oil level
1. Be sure the vehicle is on level ground.
2. Start the engine and allow it to reachnormal 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 frombeing 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.
OLM079003NOLM079004N
CAUTION
Do not overfill with engine oil. Engine damage may result.
Do not spill engine oil, when adding or changing engine oil. Ifyou drop the engine oil on the
engine room, wipe it off immedi-ately.

Changing the engine oil and filter
Have engine oil and filter changed by an
authorized HYUNDAI dealer according tothe 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 leadto cooling system and engine
damage. Also, hot coolant or steam could cause serious per-
sonal 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 irrita- tion 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 ani-
mals. Always protect your skin by
washing your hands thoroughly with soap and warm water as soon
as possible after handling used oil.

Maintenance
Check the condition and connections of all cooling system hoses and heater
hoses. Replace any swollen or deterio-
rated hoses.
The coolant level should be filled
between F and L marks on the side of the
coolant reservoir when the engine iscool.
If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the
level to F, but do not overfill. If frequent
additions are required, see an authorized
HYUNDAI dealer for a cooling systeminspection.

(Continued)
Turn the engine off and wait untilit 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.WARNING
The electric motor (cooling fan) is con-
trolled by engine
coolant temperature,
refrigerant pressure
and vehicle speed. It may some-
times operate even when the
engine is not running. Use extreme
caution when working near the
blades of the cooling fan so that
you are not injured by a rotating fan
blades. As the engine coolant tem-
perature decreases, the electric
motor will automatically shut off. This is a normal condition.
