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.
Use only the specified engine oil.
(Refer to “Recommended lubricants
and capacities” 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.
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
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 level at least once a year, at
the beginning of the winter season,
and before traveling to a colder cli-
mate.Checking the coolant level
ENGINE COOLANT
(Continued)
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
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.
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 counterclock-
wise to remove it.

Maintenance
For mixture percentage, refer to the
following table.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 around the
radiator cap before refilling the
coolant in order to prevent the
coolant from overflowing into
engine parts such as the gener-
ator.
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
Checking the parking brake
Check the stroke of the parking
brake by counting the number of
“clicks’’ heard while fully applying it
from the released position. Also, the
parking brake alone should securely
hold the vehicle on a fairly steep
grade. If the stroke is more or less
than specified, have the parking
brake adjusted by an authorized
HYUNDAI dealer.
Stroke : 5 notches at a force of
44 lbs (20 kg, 196 N).
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.
Windshield Washer fluid
agents contain some amounts
of alcohol and can be flamma-
ble under certain circum-
stances. Do not allow sparks
or flame to contact the washer
fluid or the washer fluid reser-
voir. Damage to the vehicle or
occupants could occur.
Windshield washer fluid is
poisonous to humans and ani-
mals. Do not drink and avoid
contacting windshield washer
fluid. Serious injury or death
could occur.

RECOMMENDED LUBRICANTS AND CAPACITIES
These lubricants and fluids are recommended for use in your vehicle.
*1Refer to the recommended SAE viscosity numbers on the next page.
*2Engine oils labeled Energy Conserving Oil are now available. Along with other additional benefits, they contribute to fuel economy by reducing
the amount of fuel necessary to overcome engine friction. Often, these improvements are difficult to measure in everyday driving, but in a year’s
time, they can offer significant cost and energy savings.
*
3If the API service SM engine oil is not available in your country, you are able to use API service SL, ILSAC GF-4, ACEA 3.
To help achieve proper engine and powertrain performance and durability, use only lubricants of the proper quality.
The correct lubricants also help promote engine efficiency that results in improved fuel economy.
