1.%),204/3424-3$$ " !"##$$# !"$" "$#!$Engine oil and filterThe engine oil and filter should be
changed at the intervals specified in
the maintenance schedule. If the car
is being driven in severe conditions,
more frequent oil and filter changes
are required.Drive beltsInspect all drive belts for evidence of
cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Drive belts should be checked peri-
odically for proper tension and
adjusted as necessary.When you are inspecting the belt,
place the ignition switch in the
LOCK/OFF or ACC position.
Fuel filterA clogged filter can limit the speed at
which the vehicle may be driven,
damage the emission system and
cause multiple issues such as hard
starting. If an excessive amount of
foreign matter accumulates in the
fuel tank, the filter may require
replacement more frequently.
After installing a new filter, run the
engine for several minutes, and
check for leaks at the connections.
We recommend that the fuel filter be
replaced by an authorized HYUNDAI
dealer.
Fuel lines, fuel hoses and con-
nectionsCheck the fuel lines, fuel hoses and
connections for leakage and dam-
age. We recommend that the fuel
lines, fuel hoses and connections be
replaced by an authorized HYUNDAI
dealer.
NOTICE
Diesel only
Never work on injection system
with engine running or within 30
seconds after shutting off engine.
High pressure pump, rail, injectors
and high pressure pipes are sub-
ject to high pressure even a fter
the engine stopped. The fuel jet
produced by fuel leaks may cause
serious injury, if it touch the b ody.
People using pacemakers should
not move than 30cm closer to the
ECU or wiring harness within the
eng ine room while engine is run-
ning, since the high currents in the
Common Rail system produce
considerab le magnetic fields.

age.

1.%',204/3424-3$$"!"$#!Checking the engine oil level
(Petrol engiene)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). 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 components.
Use only the specified engine oil. (Refer to "Recommended lubricantsand capacities" in chapter 8.)
Radiator hose
Be very careful not to touch the
radiator hose when checking or
adding the engine oil as i t may be
hot enough to burn you.
WARNING

#!$$Draining water from fuel filterThe 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 filterIf 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 sothat 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.i

A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 2 fuse panels, one
located in the driver’s side panel bol-
ster, the other in the engine compart-
ment near the battery.
If any of your vehicle’s lights, acces-
sories, or controls do not work, check
the appropriate circuit fuse. If a fuse
has blown, the element inside the
fuse will be melted.
If the electrical system does not
work, first check the driver’s side
fuse panel.
Before replacing a blown fuse, dis-
connect the negative battery cable.
Always replace a blown fuse with
one of the same rating.
If the replacement fuse blows, this
indicates an electrical problem. Avoid
using the system involved and imme-
diately consult an authorized
HYUNDAI dealer.Three kinds of fuses are used: blade type for lower amperage rating, slowblow type and multi fuse for higheramperage ratings.
Do not use a screwdriver or any
other metal object to remove fuses
because it may cause a short circuit
and damage the system.
