Opening the fuel filler door
The fuel filler door must be opened
from inside the vehicle by pushing
the fuel filler door opener button
located on the driver’s door.
✽ ✽NOTICE
If the fuel filler door will 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, push
the fuel filler door opener button.
3. Pull the fuel filler door (1) out to fully open.
4. To remove the cap, turn the fuel tank 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.
FUEL FILLER DOOR
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 completely
removing the cap.
Do not "top off" after the nozzle automatically shuts off when
refueling.
Tighten the cap until it clicks one time, otherwise the
Malfunction Indicator Light
will illuminate.
Always check that the fuel cap is installed securely to prevent
fuel spillage in the event of an
accident.

Features of your vehicle
When the door is open, or if the
engine is not started within 1 minute,
the tachometer pointer may move
slightly in ON position with the
engine OFF. This movement is nor-
mal and will not affect the accuracy
of the tachometer once the engine is
running.
Engine temperature gauge
This gauge shows the temperature
of the engine coolant when the igni-
tion switch is ON.
Do not continue driving with an over-
heated engine. If your vehicle over-
heats, refer to “If the engine over-
heats” in section 6.
CAUTION
Do not operate the engine with-in the tachometer's RED ZONE.
This may cause severe enginedamage.
CAUTION
If the gauge pointer movesbeyond the normal range areatoward the “H” position, it indi-cates overheating that maydamage the engine.

WARNING
Never remove the radiator cap
when the engine is hot. The
engine coolant is under pres-
sure and could cause severe
burns. Wait until the engine is
cool before adding coolant to
the reservoir.

What to do in an emergency
66
IF THE ENGINE OVERHEATS
If your temperature gauge indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine is probably too
hot. If this happens, you should:
1. Pull off the road and stop as soonas it is safe to do so.
2. Place the shift lever in P (automat- ic transmission) or neutral (manual
transmission) 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 underneath the hood,
stop the engine. Do not open the
hood until the coolant has flow
stopped. If there is no visible loss
of engine coolant and no steam,
leave the engine running and
check to be sure the engine cool-
ing 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 condition-
ing 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 bro-
ken 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
temperature has returned to nor-
mal. Then, if coolant has been lost,
carefully add coolant to the reser-
voir to bring the fluid level in the
reservoir up to the halfway mark. 7.Proceed with caution, keeping
alert for further signs of overheat-
ing. If overheating happens again,
call an authorized HYUNDAI deal-
er 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 pre-
vent injury.
WARNING
Do not remove the radiator cap
when the engine is hot. This
may result in coolant to be
blown out of the opening and
cause serious burns.
CAUTION
Serious loss of coolant indicatesthere is a leak in the cooling sys-tem and this should be checkedas soon as possible by anauthorized HYUNDAI dealer.

Maintenance
Air cleaner filter
A Genuine HYUNDAI air cleaner fil-
ter is recommended when the filter is
replaced.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.
Valve clearance
Inspect excessive valve noise and/or
engine vibration and adjust if neces-
sary. An authorized HYUNDAI dealer
should perform the operation.
Cooling system
Check cooling system components,
such as radiator, coolant reservoir,
hoses and connections for leakage
and damage. Replace any damaged
parts.
Coolant
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.
Manual transmission fluid
(if equipped)
Inspect the manual transmission
fluid according to the maintenance
schedule.
Automatic transmission fluid
Automatic transmission fluid should
not be checked under normal usage
conditions.
But in severe conditions, the fluid
should be changed at an authorized
HYUNDAI dealer in accordance to
the scheduled maintenance at the
beginning of this chapter.
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.
CAUTION
The use of a non-specified fluidcould result in transmissionmalfunction and failure.
Use only specified automatictransmission fluid. (Refer to“Recommended lubricants andcapacities” in section 8.)

Maintenance
ENGINE OIL
Checking the engine oil level
1. Be sure the vehicle is on levelground.
2. Start the engine and allow it to reach normal operating tempera-
ture.
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 com-
ponents.
Use only the specified engine oil. (Refer to “Recommended lubricantsand capacities” 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.
Do not spill engine oil, when adding or changing engine oil.If you drop the engine oil onthe engine room, wipe it offimmediately.

Maintenance
The high-pressure cooling system
has a reservoir filled with year-round
antifreeze coolant. The reservoir is
filled at the factory.
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 cli-
mate.Checking the coolant level
ENGINE COOLANT
(Continued)
Even if the engine is not oper-ating, do not remove the radi-
ator 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
Removing radiator
cap
Never attempt to remove the radiator cap while the engine
is operating or hot. Doing so
might lead to cooling system
and engine damage and could
result in serious personal
injury from escaping hot
coolant or steam.
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 counterclock-
wise to remove it.
