Features of your vehicle
Fuel gauge
The fuel gauge indicates the approxi-
mate amount of fuel remaining in the fuel
tank.
The fuel tank capacity is given in sec-
tion 8.The fuel gauge is supplemented by
a low fuel warning light, which will illumi-
nate when the fuel tank is near empty.
On inclines or curves, the fuel gauge
pointer may fluctuate or the low fuel
warning light may come on earlier than
usual due to the movement of fuel in the
tank.
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.
OHG040054
WARNING- Fuel gauge
Running out of fuel can expose
vehicle occupants to danger.
You must stop and obtain addition-
al fuel as soon as possible after the
warning light comes on or when the
gauge indicator comes close to the
E level.
CAUTION
Avoid driving with a extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damag-
ing the catalytic converter.

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,
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 (Park) and set
the parking brake. If the air condition-
ing is on, turn it off.
3. If engine coolant is running out under
the car 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 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 con-
ditioning 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 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.
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 blow out of the
opening and cause serious burns.
CAUTION
• Serious loss of coolant indicates
there is a leak in the cooling sys-
tem and we recommend that the
system be checked by an author-
ized HYUNDAI dealer.
• When the engine overheats from
low engine coolant, suddenly
adding engine coolant may cause
cracks in the engine. To prevent
damage, add engine coolant
slowly in small quantities.

Maintenance
Air cleaner filter
We recommend that the air cleaner filter
be replaced by an authoized HYUNDAI
dealer.
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 necessary.
We recommend that the system be serv-
iced by an authorized HYUNDAI dealer.
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 maintenance
schedule.
Automatic transaxle fluid
Automatic transaxle fluid should not be
checked under normal usage conditions.
We recommend that the automatic
transaxle fluid changed by an authorized
HYUNDAI dealer according to the main-
tenance schedule.
✽NOTICE
Automatic transaxle fluid color is basi-
cally red.
As the vehicle is driven, the automatic
transaxle fluid will begin to look darker.
It is normal condition and you should
not judge the need to replace the fluid
based upon the changed color.
CAUTION
The use of a non-specified fluid
could result in transaxle malfunc-
tion and failure.
Use only specified automatic
transaxle fluid. (Refer to
“Recommended lubricants and
capacities” in section 8.)WARNING
Do not disconnect and inspect
spark plugs when the engine is hot.
You may burn yourself.

Maintenance
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 (Full) and L (Low).
If it is near or at L (Low), add enough oil
to bring the level to F (Full).Do not over-
fill.
Use a funnel to help prevent oil from
being 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.
OVG079003L
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 on the
engine room, wipe it off immedi-
ately.
• When you wipe the oil level
gauge, you should wipe it with a
clean cloth. When mixed with
debris, it can cause engine dam-
age.

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 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.

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.
(Continued)
CAUTION
• When the engine overheats from
low engine coolant, suddenly
adding engine coolant may cause
cracks in the engine. To prevent
damage, add engine coolant
slowly in small quantities.
• Do not drive with no engine
coolant. It may cause water pump
failure and engine seizure, etc.

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 (Full) and L (Low) marks on
the side of the coolant reservoir when the
engine is cool.
If the coolant level is low, add enough
distilled (deionized) water. Bring the level
to F (Full), but do not overfill. If frequent
additions are required, we recommend
that the system be inspected by an
authorized HYUNDAI dealer.
Recommended engine coolant
• When adding coolant, use only deion-
ized water or soft water for your vehicle
and never mix hard water in the
coolant filled at the factory. An improp-
er coolant mixture can result in serious
malfunction or engine damage.
• The engine in your vehicle has alu-
minum engine parts and must be pro-
tected by an ethylene-glycol-based
coolant to prevent corrosion and freez-
ing.
• DO NOT USE alcohol or methanol
coolant or mix them with the specified
coolant.
• Do not use a solution that contains
more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution.(Continued)
• 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 (cool-
ing fan) is controlled by
engine coolant tempera-
ture, refrigerant pres-
sure and vehicle speed.
It may sometimes 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 temperature decreases, the
electric motor will automatically
shut off. This is a normal condition.
If your vehicle is equipped with
GDI, the electric motor (cooling fan)
may operate until you disconnect
the negative battery cable.OYF079005
