Maintenance
Checking the engine oil level
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. The level should be
between F and L.

OEU074010 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.
WARNING
Do not drive the vehicle, when
the engine oil reservoir is
empty. If not, it may damage
the engine.
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.
(Continued)
(Continued)
When you wipe the oil level
gauge, you should wipe it with
a clean cloth. When mixed
with debris, it can cause
engine damage.
CAUTION
Diesel engine
Overfilling the engine oil may
cause severe dieseling due to
churning effect. It may lead to
engine damage accompaniedwith abrupt engine speed incre-
ment, combustion noise andwhite smoke emission.
CAUTION

Maintenance
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 lubricantsand capacities” in section 8.)
Changing the engine oil and filter
We recommend that the engine oil
and filter be replaced by an author-
ized HYUNDAI dealer.
OEU074011
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 soapand warm water as soon as pos-
sible after handling used oil.
WARNING

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 thebeginning of the winter season, and
before traveling to a colder climate.Checking the coolant level
EENN GGIINN EE CC OO OOLLAA NN TT

Do not drive with no engine
coolant. It may cause waterpump failure and engine
seizure, etc.
When the engine overheats
from low engine coolant, sud-
denly adding engine coolant
may cause cracks in the
engine. To prevent damage,
add engine coolant slowly insmall quantities.
CAUTION
Removing radiator
cap
Never attempt to remove the radiator cap while the engine
is operating or hot. Doing somight lead to cooling system
and engine damage and could
result in serious personal
injury from escaping hotcoolant 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 fromthe cooling system.
(Continued)
WARNING (Continued)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 plugwhile 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 and L marks on the side
of the coolant reservoir when theengine is cool.
If the coolant level is low, add enough
specified coolant to provide protec-tion against freezing and corrosion.
Bring the level to F, but do not over-
fill. If frequent additions are required,
we recommend that the system be
inspected by an authorized
HYUNDAI dealer.
Recommended engine coolant
When adding coolant, use onlydeionized 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 ethylene-glycol-
based coolant to prevent corrosionand 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 thesolution.
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 theengine coolant temperature
decreases, the electric motor
will automatically shut off. Thisis a normal condition.WARNING

Radiator cap
Do not remove the radiator cap when the engine and radiator
are hot. Scalding hot coolant
and steam may blow out underpressure causing serious
injury.
WARNING
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.
CAUTION
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 brake 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 fluid, clean the
area around the reservoir cap thor-
oughly to prevent brake fluid contam-ination.
If the level is low, add fluid to the
MAX level. The level will fall with
accumulated mileage.This is a normal condition associated
with the wear of the brake linings. If
the fluid level is excessively low, werecommend that the system be
checked by an authorized HYUNDAI
dealer.
Information
Use only the specified brake fluid.
(Refer to “Recommended lubricants
or capacities” in section 8.)
Never mix different types of fluid.
Before removing the brake/clutch
filler cap, read the warning on thecap.

When changing and adding
brake fluid, handle it carefully.Do not let it come in contact
with your eyes. If brake fluidshould 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.

MaintenanceUse only the specified power steer-ing fluid. (Refer to "Recommendedlubricants or capacities" in section 9.)
Checking the power steering hose
Check the connections for oil leaks,
damage and twists in the power
steering hose before driving.
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 char-
acteristics in cold climates to preventfreezing.
(Continued)
Too little fluid can result in
increased steering effort
and/or noise from the powersteering system.
The use of the non-specified
fluid could reduce the effec-
tiveness of the power steering
system and cause damage toit.

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, we recommend that
the system be serviced by an author-
ized HYUNDAI dealer.
Stroke : 7 “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 waterin its bottom.
If water accumulates inthe fuel filter, the warninglight comes on when the
ignition switch is in the ONposition.
If this warning light turned
on, we recommend that
the system be serviced by
an authorized HYUNDAI
dealer.
Fuel filter cartridge replace- ment
When replacing the fuel filter car-
tridge, we recommend that you
use parts for replacement from an
authorized HYUNDAI dealer.
