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 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.
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 on
the engine room, wipe it off
immediately.

Maintenance

Use only the specified engine oil.
(Refer to “Recommended lubricants
and capacities” in section 8.)Changing the engine oil and
filter
Have engine oil and filter changed by
an authorized HYUNDAI dealer
according to the Maintenance
Schedule at the beginning of this
section.
WARNING
Used engine oil may cause irri-
tation or cancer of the skin if
left in contact with the skin for
prolonged periods of time.
Always protect your skin by
washing your hands thoroughly
with soap and warm water as
soon as possible after handling
used oil.

ENGINE COOLANT
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 concentration level at least
once a year, at the beginning of the
winter season, and before traveling
to a colder climate.
Checking the coolant level
(Continued)
• 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.
• 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
The electric motor
(cooling fan) is con-
trolled by engine
coolant temperature,
refrigerant pressure
and vehicle speed. It may some-
times 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 if equipped
with GDI, the electric motor
(cooling fan) may operate until
you disconnect the negative
battery cable.
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.

Maintenance
38 7
Check the condition and connections
of all cooling system hoses and
heater hoses. Replace any swollen
or deteriorated hoses.
The coolant level should be filled
between F (MAX) and L (MIN) marks
on the side of the coolant reservoir
when the engine is cool.
If the coolant level is low, add enough
deonized water. Bring the level to F
(MAX), but do not overfill. If frequent
coolant refill is required, see an
authorized HYUNDAI dealer for a
cooling system inspection.
Recommended engine coolant
• When adding coolant, use only
deionized water for your vehicle
and never mix hard water in the
coolant filled at the factory. An
improper coolant mixture can
result in serious malfunction or
engine damage.
• The engine in your vehicle has alu-
minum engine parts and must be
protected by an ethylene-glycol-
based coolant to prevent corrosion
and freezing.
• DO NOT USE alcohol or methanol
coolant or mix them with the spec-
ified 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.For mixture percentage, refer to the
following table.

Maintenance
Changing the coolant
Have coolant changed by an author-
ized HYUNDAI dealer according to
the Maintenance Schedule at the
beginning of this section.
WARNING
Radiator cap
Do not remove the radiator cap
when the engine and radiator
are hot. Scalding hot coolant
and steam may blow out under
pressure causing serious
injury.
CAUTION
Put a thick cloth or fabric
around the radiator cap before
refilling the coolant in order to
prevent the coolant from over-
flowing into engine parts such
as generator.
WARNING - Coolant
• Do not use radiator coolant or
antifreeze in the washer fluid
reservoir.
• Radiator coolant can severely
obscure visibility when
sprayed on the windshield
and may cause loss of vehicle
control or damage to paint
and body trim.

Maintenance
WARNING - Brake fluid
When changing and adding
brake fluid, handle it carefully.
Do not let it come in contact
with your eyes. If brake fluid
should come in contact with
your eyes, immediately flush
them with a large quantity of
fresh tap water. Have your eyes
examined by a doctor as soon
as possible.
CAUTION
Do not allow brake fluid to con-
tact the vehicle's body paint, as
paint damage will result. Brake
fluid, which has been exposed
to open air for an extended time
should never be used as its
quality cannot be guaranteed. It
should be disposed of properly.
Do not put in the wrong type of
fluid. A few drops of mineral-
based oil, such as engine oil, in
your brake system can damage
brake system parts.

Maintenance
44 7
Replace the filter according to the
Maintenance Schedule.
If the vehicle is operated in extreme-
ly dusty or sandy areas, replace the
element more often than the usual
recommended intervals. (Refer to
“Maintenance under severe usage
conditions” in this section.)
CAUTION
• Do not drive with the air clean-
er removed; this will result in
excessive engine wear.
• When removing the air cleaner
filter, be careful that dust or
dirt does not enter the air
intake, or damage may result.
• Use a HYUNDAI genuine part.
Use of nongenuine part could
damage the air flow sensor.

Maintenance
Battery recharging
Your vehicle has a maintenance-free,
calcium-based battery.
• If the battery becomes discharged
in a short time (because, for exam-
ple, the headlights or interior lights
were left on while the vehicle was
not in use), recharge it by slow
charging (trickle) for 10 hours.
• If the battery gradually discharges
because of high electric load while
the vehicle is being used, recharge
it at 20-30A for two hours.(Continued)
• When lifting a plastic-cased
battery, excessive pressure
on the case may cause battery
acid to leak, resulting in per-
sonal injury. Lift with a battery
carrier or with your hands on
opposite corners.
• Never attempt to recharge the
battery when the battery
cables are connected.
• The electrical ignition system
works with high voltage.
Never touch these compo-
nents with the engine running
or the ignition switched on.
Failure to follow the above
warnings can result in serious
bodily injury or death.CAUTION
• Always charge the battery
fully to prevent battery case
damage in low temperature
area.
• If you connect unauthorized
electronic devices to the bat-
tery, the battery may dis-
charge. Never use unautho-
rized devices.
