#!$$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

!#$ "$#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 theelement more often than the usualrecommended intervals. (Refer to“Maintenance under severe usageconditions” in this chapter.)
• Do not drive with the filter removed; this will result in exces-
sive engine wear.
• When replacing th e air cleaner fil-
ter, 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 re placement from an author-
ized HYUNDAI dealer.NOTICE

OIB074018
Don’t clean the used filter. It can
cause contaminations on the
clean side of filter to result in
engine wear or sensors’ failure.

Battery rechargingYour vehicle has a maintenance-free,
calcium-based battery.
• If the battery becomes dischargedin a short time (because, for exam-
ple, the headlights or interior lights
were left on while the vehicle was
not in use), recharge it by slow
charging (trickle) for 10 hours.
• If the battery gradually discharges because of high electric load while
the vehicle is being used, recharge
it at 20-30A for two hours.

Example
(Continued)•
Never attempt to recharge the
battery when the battery cables
are connected.
•
The electrical ignition system
works with high voltage. Never
touch these components with
the engine run ning or the igni-
tion switched on.
Failure to follow the above warn-
ings can result in serious bodily
injury or death.

•
Disconnect the battery charger
in the following order.
1.Turn off the battery charger main switch.
2.Unho ok the negative clamp from
the negative battery terminal.
3.Unhook the positive clamp from the positive battery terminal.
•
Before performing maintenance
or recharging the battery, turn
off all accessories and stop the
engine.
•
The negative battery cable must
be removed first and installed
last when the battery is discon-
nected.
WARNING
Recharging battery
When recharging the battery,
observe the following precautions:•
The battery must be removed
from the vehicle and placed in
an area with good ventilation.
•
Do not allow cigarettes, sparks,
or flame near the battery.
•
Watch the battery during charg-
ing, and stop or reduce the
charging rate if the battery cells
begin gas sing (boiling) violently
or if the temperature of the elec-
trolyte of any cell exceeds 49°C
(120°F).
•
Wear eye protection when
checking the battery during
charging.

WARNING

,204/3424-3
$
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.

The actual fuse/relay panel label may
differ from equipped items. iNOTICENOTICE

Fuse replacement•
Never replace a fuse with any-
thing but another fuse of the
same rating.
•
A higher capacity fuse could
cause damage and possibly a
fire.
•
Never install a wire or aluminum
foil instead of the proper fuse -
even as a temporary repair. It
may ca use extensive wiring
damage and a possible fire.

3. Pull the suspected fuse straightout. Use the fuse puller provided in
the engine compartment fuse
panel.
4. Check the removed fuse; replace it if it is blown. 5. Push in a new fuse of the same
rating, and make sure it fits tightly
in the clips.
If it fits loosely, we recommend that
you consult an authorized HYUNDAI
dealer.
If you do not have a spare, use a fuse of the same rating from a circuityou may not need for operating thevehicle, such as the cigarette lighterfuse.If the electrical components do not
work and the fuses are OK, check
the fuse panel in the engine com-
partment. If a fuse is blown, it must
be replaced.
MMemory fuse Your vehicle is equipped with the
memory fuse to prevent battery dis-
charge if your vehicle is parked with-
out being operated for prolonged
periods. Use the following proce-
dures before parking the vehicle for
prolonged periods.
1. Turn off the engine.
2. Turn off the headlights and tail lights.
3. Open the driver's side panel cover and pull up the memory fuse.

IInformation
If the memory fuse is pulled up from
the fuse panel, the warning chime,
audio, clock and interior lamps, etc.,
will not operate. Some items must
be reset after replacement. Refer to
"Battery" in this chapter.
Even though the memory fuse is pulled up, the battery can still be
discharged by operation of the
headlights or other electrical
devices.
Engine compartment panel fuse
replacement1. Turn the ignition switch and all
other switches off.
2. Remove the fuse box cover by pressing the tab and pulling up the
cover.
3. Check the removed fuse; replace it if it is blown. To remove or insert
the fuse, use the fuse puller in the
engine compartment fuse panel.
4. Push in a new fuse of the same rating, and make sure it fits tightly
in the clips. If it fits loosely, we rec-
ommend that you consult an
authorized HYUNDAI dealer.
After checking the fuse panel in the
engine compartment, securely install
the fuse panel cover. If not, electrical
failures may occur from water leak-
ing in.NOTICE
