Maintenance
• Do not overfill the engine oil. It may damage the engine.
• 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.

Maintenance
Checking the engine oil level
(Diesel Engine)1. Be sure the vehicle is on levelground.
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.
6. The level should be in the C range. If the level is in the D range, add
enough engine oil to bring the
level up to the C range.FigureRequired action
Range
(A)Recommend to contact a HYUNDAI
authorised repairer.
Range(B)Do not refill engine oil.
Range(C)Normal.
You may add engine oil as long as
the oil level does not go above the
C range.
Range(D)You must add oil and make sure
that the oil level is in the C Range.

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.

Maintenance
Used engine oil may cause irri-
tation 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 lab-
oratory animals. Always protect
your skin by washing your
hands thoroughly with soap
and warm water as soon as pos-
sible after handling used oil.

Maintenance
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 travelling
to a colder climate.
• When the engine overheats fromlow 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.Checking the engine coolant
level
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 MAX and MIN marks on the
side of the coolant reservoir when
the engine is cool.
If the coolant level is low, add enough
distilled (deionised) or soft water.
Bring the level to MAX, but do not
overfill.
If frequent additions are required, we
recommend that the system be inspect-
ed by a HYUNDAI authorised repairer.

Maintenance
Removing radiatorcap
• Never attempt to remove the
radiator cap whilst 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 whilst
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
whilst the engine and radiator
are hot. Hot coolant and
steam may still blow out
under pressure, causing seri-
ous injury.
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
Make sure the coolant cap is prop-
erly closed after refill of coolant.
Otherwise the engine could be over-
heated whilst driving.
1. Check if the radiator cap label is straight In front.
(Continued)(Continued)
2. Make sure that the tiny protru-
sions inside the coolant cap
should be securely interlocked.
Recommended engine coolant
• When adding coolant, use onlydeionised water or soft water for
your vehicle and never mix hard
water in the coolant filled at the fac-
tory. 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 Phosphate-based
Ethylene glycol 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 solu-
tion.

Maintenance
For mixture percentage, refer to the
following table.
Information
If in doubt about the mix ratio, a 50%
water and 50% antifreeze mix is the
easiest to mix together as it will be the
same quantity of each. It is suitable to
use for most temperature ranges of
-35°C (-31°F) and higher.
Changing the engine coolant
We recommend that coolant be
changed by a HYUNDAI authorised
repairer.
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 generator.

Maintenance
BRAKE/CLUTCH FLUID (IF EQUIPPED)
Checking the brake/clutch
fluid level
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX and MIN 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
level. The level will fall with accumulat-
ed mileage. This is a normal condition
associated with the wear of the brake
linings.If the fluid level is excessively low,
we recommend that the system be
checked by a HYUNDAI authorised
repairer.
Information
Use only the specified brake/clutch
fluid. (Refer to “Recommended lubri-
cants and capacities” in chapter 8.)
Information
Before removing the brake/clutch filler
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.
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 disposed of properly.
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 damage brake/
clutch system parts.

OTLE078009R
In the event the brake/clutch
system requires frequent addi-
tions of fluid, we recommend
that the system be inspected by
a HYUNDAI authorised repairer.
WARNING
When changing and adding
brake/ clutch fluid, handle it
carefully. Do not let it come in
contact with your eyes. If brake/
clutch fluid should 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.

WASHER FLUID
Checking the washer fluid
level
The reservoir is translucent so that
you can check the level with a quick
visual inspection.
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 whilst 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 serviced by a
HYUNDAI authorised repairer.
Stroke : 5~6 “clicks’’ at a force of
20 kg (44 lbs, 196 N).
