Features of your vehicle
Engine coolant temperature gauge
(if equipped)
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 chapter 6.
Fuel gauge
The fuel gauge indicates the approximate
amount of fuel remaining in the fuel tank.
The fuel tank capacity is given in chapter
8. The fuel gauge is supplemented by a
low fuel warning light, which will illuminate
when the fuel tank is nearly empty.
On inclines or curves, the fuel gauge
pointer may fluctuate or the low fuel warn-
ing light may come on earlier than usual
due to the movement of fuel in the tank.
OBA043107
CAUTION
If the gauge pointer moves beyond
the normal range area toward the
“H” it indicates overheating that
may damage the engine.
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.

What to do in an emergency
IF THE ENGINE OVERHEATS
If your temperature gauge indicates over-
heating, you will experience a loss of
power, or hear loud pinging or knocking
sound, the engine will probably be too
hot. If this happens, you should:
1. Pull the vehicle 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 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 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 leakage 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 we recom-
mend that you call an authorized
HYUNDAI dealer.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, we recom-
mend that you call an authorized
HYUNDAI dealer.
CAUTION
Serious loss of coolant indicates
there is a leak in the cooling system
and we recommend that the system
be checked by an authorized
HYUNDAI dealer.
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.

Maintenance
At least monthly:
• Check the coolant level in the engine
coolant 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 the radiator, heater and air con-
ditioning 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.
At least once a year:
• Clean the body and door drain holes.
• Lubricate the door hinges and checks,
and hood hinges.
• Lubricate the door and hood locks and
latches.
• Lubricate the door rubber weather-
strips.
• Check the air conditioning system.
• Inspect and lubricate the automatic
transaxle linkage and controls.
• Clean the battery and terminals.
• Check the brake (and clutch) fluid
level.

Air cleaner filter
When replacing the air cleaner filter, we
recommend that you use HYUNDAI gen-
uine parts.
Spark plugs
Make sure to install new spark plugs of
the correct heat range.
Valve clearance (if equipped)
Inspect for excessive valve noise and/or
engine vibration and adjust if necessary.
We recommend that the system be serv-
iced by an authorized HYUNDAI dealer.
Cooling system
Check the cooling system components,
such as the 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 maintenance
schedule.
Manual transaxle fluid
(if equipped)
Inspect the manual transaxle fluid
according to the maintenance schedule.
Automatic transaxle fluid
(if equipped)
Inspect the automatic transaxle fluid
according to the maintenance schedule.
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated or
damaged parts immediately.
Brake fluid
Check the brake fluid level in the brake
fluid reservoir. The level should be
between “MIN” and “MAX” marks on the
side of the reservoir. Use only hydraulic
brake fluid conforming to DOT 3 or DOT
4 specification.
Parking brake
Inspect the parking brake system includ-
ing the parking brake lever and cables.

ENGINE OIL
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 capac-
ities” in chapter 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.
OBA073002OBA073003
CAUTION
Do not overfill the engine oil. It may
damage the engine.

Maintenance
ENGINE COOLANT
Changing the engine oil and filter
We recommend that the engine oil and
filter be replaced by an authorized
HYUNDAI dealer.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.
Checking the coolant level
WARNING
Used engine oil may cause skin irri-
tation or cancer if left in contact
with the skin for prolonged periods
of time. Used engine oil contains
chemicals that have caused cancer
in laboratory animals. Always pro-
tect your skin by washing your
hands thoroughly with soap and
warm water as soon as possible
after handling used oil.
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.
• 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.
