Opening the fuel filler lid
The fuel filler lid must be opened from
inside the vehicle by pressing the fuel
filler lid open button located on the dri-
ver’s door.
✽✽
NOTICE
If the fuel filler lid does not open
because ice has formed around it, tap
lightly or push on the lid to break the ice
and release the lid. Do not pry on the lid.
If necessary, spray around the lid 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. Push the fuel filler lid opener button, then the fuel filler lid slowly open (1).
3. To remove the cap, turn the fuel tank cap (2) counterclockwise.
4. Refuel as needed. Closing the fuel filler lid
1. To install the cap, turn it clockwise until
it “clicks”. This indicates that the cap is securely tightened.
2. Close the fuel filler lid and push it light- ly and make sure that it is securelyclosed.

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.
Always check that the fuel cap is installed securely to prevent fuel
spillage in the event of an acci-dent.

Features of your vehicle
Tachometer
The tachometer indicates the approxi-
mate number of engine revolutions per
minute (rpm). Use the tachometer to select the correct
shift points and to prevent lugging and/or
over-revving the engine.
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
normal 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 engine
start/stop button is 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 damage.
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 and set the parking brake. If the air conditioning 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 notopen 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.
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.
CAUTION
Serious loss of coolant indicates there is a leak in the cooling systemand this should be checked as soonas possible by an authorized HYUNDAI dealer.

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 steering
effort or looseness in the steering
wheel, or change in its straight-aheadposition.
Notice if your vehicle constantly turns slightly or “pulls” to one side when trav-
eling 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 oper- ation 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 condition-
ing system during or after use is nor-mal).
At least monthly:
Check coolant level in the enginecoolant reservoir.
Check the operation of all exterior lights, including the stoplights, turn sig-
nals and hazard warning flashers.
Check the inflation pressures of all tires including the spare.
At least twice a year
(i.e., every Spring and Fall):
Check radiator, heater and air condi- tioning hoses for leaks or damage.
Check windshield washer spray and wiper operation. Clean wiper blades
with clean cloth dampened with wash-er fluid.
Check headlight alignment.
Check muffler, exhaust pipes, shields and clamps.
Check the lap/shoulder belts for wear and function.
Check for worn tires and loose wheel lug nuts.
