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 reinsert it fully.
5.Pull the dipstick out again and
check the level. The level should be
between F (Full) and L (Low). 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 damage.
- Diesel Engine
Overfilling the diesel engine oil
may cause severe dieseling due to
the churning effect. It may damage
the diesel engine with the abrupt
engine speed incensement, com-
bustion noise, and white smoke
emission.
NOTICE
NOTICE
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.

If it is near or at L (Low), add enough
oil to bring the level to F (Full).
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 chapter 8.)
Changing the engine oil and
filter
We recommend that the engine oil
and filter be replaced by an author-
ized HYUNDAI dealer.
Used engine oil may cause skin
irritation or cancer if left in con-
tact with the skin for prolonged
periods of time. Used engine oil
contains chemicals that have
caused cancer in laboratory
animals. Always protect your
skin by washing your hands
thoroughly with soap and warm
water as soon as possible after
handling used oil.

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.
Do not drive with no engine
coolant. It may cause water
pump failure and engine seizure,
etc.
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 quanti-
ties.Checking the coolant level
NOTICE
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.
(Continued)
WARNING
(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 counter-
clockwise 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.

Maintenance
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 (Full) and L (Low)
marked on the side of the coolant
reservoir when the engine is cool.If the coolant level is low, add enough
distilled (deionized) water (except
Middle East) or add enough pre-
mixed coolant (for Middle East).
Bring the level to F (Full), but do not
overfill. If frequent additions are
required, we recommend that the
system be inspected by an author-
ized HYUNDAI dealer. 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.
The electric motor (cooling fan)
may operate until you discon-
nect the negative battery cable.

Maintenance
Recommended engine coolant
Use only soft (distilled) water in the
coolant mixture.
The engine in your vehicle has alu-
minum engine parts and must be
protected by a phosphate-based
ethylene glycol coolant for alu-
minum radiator 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.
Changing the coolant
We recommend that the coolant be
replaced by an authorized HYUNDAI
dealer.
Put a thick cloth or fabric around
the radiator cap before refilling
the coolant in order to prevent the
coolant from overflowing into
engine parts such as the alterna-
tor.

Checking the brake/clutch
fluid level
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX (Maximum) and MIN
(Minimum) marks on the side of the
reservoir.Before removing the reservoir cap
and adding brake/clutch fluid, clean
the area around the reservoir cap
thoroughly to prevent brake/clutch
fluid contamination. If the level is low,
add fluid to the MAX (Maximum)
level. The level will fall with accumu-
lated mileage. This is a normal con-
dition associated with the wear of the
brake linings and/or clutch disc (if
equipped).
If the fluid level is excessively low, we
recommend that the system be
checked by an authorized HYUNDAI
dealer.
Use only the specified brake/clutch
fluid. (Refer to “Recommended lubri-
cants or capacities” in chapter 8.)
Information
Before removing the brake/clutch fil-
ter cap, read the warning on the cap
Information
Clean filler cap before removing. Use
only DOT3 or DOT4 brake/clutch
fluid from a sealed container.

Loss of brake fluid
In the event the brake system
requires frequent additions of
fluid, we recommend that the
system be inspected by an
authorized HYUNDAI dealer.

Maintenance
Do not allow brake/clutch fluid to
contact the vehicle's body paint,
as paint damage will result.
Brake/clutch fluid, which has been
exposed to open air for an extend-
ed time should never be used as
its quality cannot be guaranteed. It
should be properly disposed.
Don't put in the wrong kind of
fluid. A few drops of mineral-
based oil, such as engine oil, in
your brake/clutch system can dam-
age brake/clutch system parts.
NOTICE
Brake/clutch fluid
When changing and adding
brake/clutch fluid, handle it
carefully. Do not let it come in
contact with your eyes. If
brake/clutch fluid come in con-
tact 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.

Checking the washer fluid
level
Check the fluid level in the washer
fluid reservoir and add fluid if neces-
sary. Plain water may be used if
washer fluid is not available.
However, use washer solvent with
antifreeze characteristics in cold cli-
mates to prevent freezing.Do not use engine coolant or
antifreeze in the washer fluid
reservoir.
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, we recommend
that the system be inspected by an
authorized HYUNDAI dealer.
Stroke : 6~8 “clicks’’ at a force of
20 kg (44 lbs, 196 N).

Draining water from fuel filter
The fuel filter for diesel engine plays
an important role of separating water
from fuel and accumulating the water
in its bottom.
If water accumulates in the fuel filter,
the warning light comes on when the
ignition switch is in the ON position.
If this warning light turned
on, we recommend that the
system be serviced by an
authorized HYUNDAI dealer.
If the water accumulated in the
fuel filter is not drained at proper
times, damages to the major parts
such as the fuel system can be
caused by water permeation in the
fuel filter.
Extracting air from the fuel filter
If you drive until you have no fuel left
or if you replace the fuel filter, be
sure to extract air from the fuel sys-
tem as it makes it difficult to start the
engine.
1. Pump up and down(1) approxi-
mately 50 times until the pump is
hard.
2. Extract air from the fuel filter by
removing the bolt(2) with a cross-
tip screw driver and reinstall the
bolt(2).
3. Pump up and down(1) approxi-
mately 15 times.4. Extract air from the fuel filter by
removing the bolt(2) with a cross-
tip screw driver and reinstall the
bolt(2).
5. Pump up and down(1) approxi-
mately 5 times.
Information
• Use cloths when you extract air so
that the fuel is not sprayed around.
• Clean the fuel around the fuel filter
or the injection pump before start-
ing the engine to prevent fire.
• Finally, check each part if the fuel is
leaking.

Filter replacement
You can clean the filter when inspect-
ing the air cleaner element.
Clean the filter by using compressed
air.
1. Loosen the air cleaner cover
attaching clips and open the cover.2. Remove the used filter and wipe
the inside of the air cleaner hous-
ing carefully not to remain dusts in
the cover housing.
3. Place new filter with clean hands
and ensure the rubber gasket is
not taken off.
4. Lock the cover with attaching clips.
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 chapter.)
Do not drive with the filter
removed; this will result in
excessive engine wear.
When replacing the air cleaner
filter, be careful that dust or dirt
does not enter the air intake, or
damage may result.
Keep the new filter clean of any
contamination while replacing.
We recommend that you use
parts for replacement from an
authorized HYUNDAI dealer.
NOTICE
