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.

Outside rearview mirror
Be sure to adjust mirror angles
before driving.
Your vehicle is equipped with both
left-hand and right-hand outside
rearview mirrors. The mirrors can be
adjusted remotely with the remote
switch. The mirror heads can be fold-
ed back to prevent damage during an
automatic car wash or when passing
in a narrow street.
WARNING - Rearview
mirrors
The right outside rearview
mirror is convex. Objects seen
in the mirror are closer than
they appear.
Use your interior rearview
mirror or direct observation to
determine the actual distance
of following vehicles when
changing lanes.
CAUTION
Do not scrape ice off the mirror
face; this may damage the sur-
face of the glass. If ice should
restrict movement of the mirror,
do not force the mirror for
adjustment. To remove ice, use
a deicer spray, or a sponge or
soft cloth with warm water.
CAUTION
If the mirror is jammed with ice,
do not adjust the mirror by force.
Use an approved spray de-icer
(not radiator antifreeze) to
release the frozen mechanism or
move the vehicle to a warm place
and allow the ice to melt.
WARNING
Do not adjust or fold the outside
rearview mirrors while the vehi-
cle is moving. This could result in
loss of control, and an accident
which could cause death, seri-
ous injury or property damage.

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 engine
damage.
CAUTION
If the gauge pointer moves
beyond the normal range area
toward the “H” position, it indi-
cates overheating that may
damage 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
6 6
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 soon
as 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 indicates
there is a leak in the cooling sys-
tem and this should be checked
as soon as possible by an
authorized HYUNDAI dealer.

Maintenance
6 7
While operating your vehicle:
Note any changes in the sound of
the exhaust or any smell of
exhaust fumes in the vehicle.
Check for vibrations in the steering
wheel. Notice any increased steer-
ing effort or looseness in the steer-
ing wheel, or change in its straight-
ahead position.
Notice if your vehicle constantly
turns slightly or “pulls” to one side
when traveling on smooth, level
road.
When stopping, listen and check
for unusual sounds, pulling to one
side, increased brake pedal travel
or “hard-to-push” brake pedal.
If any slipping or changes in the
operation of your transmission
occurs, check the transmission
fluid level.
Check automatic transmission P
(Park) function.
Check parking brake.
Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
Check the coolant level in the
engine coolant reservoir.
Check the operation of all exterior
lights, including the stoplights, turn
signals and hazard warning flash-
ers.
Check the inflation pressures of all
tires including the spare.
At least twice a year
(i.e., every Spring and Fall):
Check the radiator, heater and air
conditioning hoses for leaks or
damage.
Check the windshield washer
spray and wiper operation. Clean
the wiper blades with clean cloth
dampened with washer fluid.
Check the headlight alignment.
Check the muffler, exhaust pipes,
shields and clamps.
Check the lap/shoulder belts for
wear and function.
Check for worn tires and loose
wheel lug nuts.

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 fluid
could result in transmission
malfunction and failure.
Use only specified automatic
transmission fluid. (Refer to
“Recommended lubricants and
capacities” in section 8.)
