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 traveling
to a colder climate.
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 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 (or F (Full)
and L (Low)) marks on the side of the
coolant reservoir when the engine is
cool.
If the coolant level is low, add enough
distilled (deionized) water. Bring the
level to MAX, (or F (Full)) but do not
overfill.
If frequent additions are required, we
recommend that the system be
inspected by an authorized HYUNDAI
dealer.

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 an authorized HYUNDAI
dealer.
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
extended time should never be
used as its quality cannot be
guaranteed. It should be dis-
posed 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.

If the brake/clutch system
requires frequent additions of
fluid this could indicate a leak in
the brake/clutch system. We
recommend that the vehicle be
inspected by an authorized
HYUNDAI dealer.
WARNING
Do not allow brake/clutch fluid
to come in contact with your
eyes. If brake/clutch fluid comes
in contact with your eyes, flush
your eyes with clean water for at
least 15 minutes and get imme-
diate medical attention.

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.
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 : 5~6 “clicks’’ at a force of
20 kg (44 lbs, 196 N).OPD076017

To prevent serious injury or
death, take the following safety
precautions when using washer
fluid:
Do not use engine coolant or
antifreeze in the washer fluid
reservoir. Engine coolant can
severely obscure visibility
when sprayed on the wind-
shield and may cause loss of
vehicle control resulting in an
accident or damage to paint
and body trim.
Do not allow sparks or flame
to contact the washer fluid or
the washer fluid reservoir.
Washer fluid may contain
alcohol and can be flamma-
ble.
Do not drink washer fluid and
avoid contact with skin.
Washer fluid is poisonous to
humans and animals.
Keep washer fluid away from
children and animals.

Draining water from fuel filter
The fuel filter in the diesel engine
operates the critical function of sepa-
rating water from the fuels and accu-
mulating the water in its bottom.
When enough water is accumulated
inside the fuel filter, the warning light
( ) illuminates with the ignition
switch in the ON position.
In this case, we recommend you to
have the system checked by an
authorized HYUNDAI dealer.
When the accumulated water is not
drained at a proper timing, water
may permeate in the fuel filter,
damaging the major vehicle com-
ponents, such as the fuel system.
Fuel filter cartridge replace-
ment
We recommend the fuel filter car-
tridge be replaced by an authorized
HYUNDAI dealer according to the
Maintenance Schedule at the begin-
ning of this chapter.
Filter replacement
The air cleaner filter can be cleaned
for inspection using compressed air.
Do not attempt to wash or to rinse it,
as water will damage the filter.
If soiled, the air cleaner filter must be
replaced.NOTICE

1. Loosen the air cleaner coverattaching clips and open the cover. 2. Wipe the inside of the air cleaner.
3. Replace the air cleaner filter.
4. Lock the cover with the cover
attaching clips.
5. Check if the cover is firmly installed.
Information
If the vehicle is operated in extremely
dusty or sandy areas, replace the element
more often than the usual recommended
intervals (refer to “Maintenance Under
Severe Usage Conditions” in this chap-
ter).
Do not drive with the air cleaner filter removed. This will result in
excessive engine wear.
When removing the air cleaner filter, be careful that dust or dirt
does not enter the air intake, or
damage may result.

Battery recharging
By battery charger
Your 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. Always follow these instructions
when recharging your vehicle’s
battery to avoid the risk of SERI-
OUS INJURY or DEATH from
explosions or acid burns:
Before performing mainte-
nance or recharging the bat-
tery, turn off all accessories
and place the Engine Start/
Stop button to the OFF posi-
tion.
Keep all flames, sparks, or
smoking materials away from
the battery.
Always work outdoors or in an
area with plenty of ventilation.
Wear eye protection when
checking the battery during
charging.
The battery must be removed
from the vehicle and placed in
a well ventilated area.
(Continued)
WARNING (Continued)
Watch the battery during
charging, and stop or reduce
the charging rate if the battery
cells begin boiling violently.
The negative battery cable
must be removed first and
installed last when the battery
is disconnected. Disconnect
the battery charger in the fol-
lowing order:
(1) Turn off the battery chargermain switch.
(2) Unhook the negative
clamp from the negative
battery terminal.
(3) Unhook the positive clamp from the positive battery
terminal.
Always use a genuine HYUNDAI
approved battery when you
replace the battery.

A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 2 (or 3) fuse panels,
one located in the driver’s side panel
bolster, the other in the engine com-
partment.
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 or broken.
If the electrical system does not
work, first check the driver’s side
fuse panel. Before replacing a blown
fuse, turn the engine and all switches
off, and then disconnect the negative
battery cable. Always replace a
blown fuse with one of the same rat-
ing.
If the replacement fuse blows, this indi-
cates an electrical problem. Avoid
using the system involved and immedi-
ately consult an authorized HYUNDAI
dealer.Information
Three kinds of fuses are used: blade
type for lower amperage rating, car-
tridge type, and multi fuse for higher
amperage ratings.
Do not use a screwdriver or any
other metal object to remove
fuses because it may cause a
short circuit and damage the sys-
tem.

NEVER replace a fuse with any-
thing but another fuse of the
same rating.
A higher capacity fuse could
cause damage and possibly
cause a fire.
Do not install a wire or alu-
minum foil instead of the
proper fuse - even as a tem-
porary repair. It may cause
extensive wiring damage and
possibly a fire.

Instrument panel fuse replace-
ment
1. Turn the vehicle off.
2. Turn all other switches OFF.
3. Open the fuse panel cover.
4. Refer to the label on the inside ofthe fuse panel cover to locate the
suspected fuse location. 5. Pull the suspected fuse straight
out. Use the removal tool provided
in the engine compartment fuses
panel.
6. Check the removed fuse; replace it if it is blown. Spare fuses are pro-
vided in the instrument panel fuse
panels (or in the engine compart-
ment fuse panel).
7. Push in a new fuse of the same rating, and make sure it fits tightly
in the clips. If it fits loosely, consult
an authorized HYUNDAI dealer. In an emergency, if you do not have
a spare fuse, use a fuse of the same
rating from a circuit you may not
need for operating the vehicle, such
as the cigarette lighter fuse.
If the headlamps or other electrical
components do not work and the
fuses are OK, check the fuse panel
in the engine compartment. If a fuse
is blown, it must be replaced with the
same rating.

4. Check the removed fuse; replace itif it is blown. To remove or insert
the fuse, use the fuse puller in the
engine compartment fuse panel.
5. Push in a new fuse of the same rating, and make sure it fits tightly
in the clips. If it fits loosely, consult
an authorized HYUNDAI dealer.
After checking the fuse panel in
the engine compartment, securely
install the fuse panel cover. You
may hear a clicking sound if the
cover is securely latched. If it is
not securely latched, electrical
failure may occur from water con-
tact.Main fuse
The electronic system may not func-
tion correctly even when the fuses
located in the engine compartment
and instrument panel are not discon-
nected. In such case, the cause of
the problem may be disconnection of
the main fuse (BFT type), which is
located inside the positive battery
terminal (+) cap. Since the main fuse
is designed more intricately than
other parts, we recommend you visit
the nearest HYUNDAI dealer.
Information
After inspection always securely
install the battery cap. If it is not
securely latched, electrical failure may
occur from water contact.
Multi fuse
If the multi fuse is blown, it must be
removed as follows:
1. Turn the vehicle off.
2. Disconnect the negative battery cable.
3. Remove the fuse panel cover by pressing the tab and pulling it up.
4. Remove the nuts shown in the pic- ture above.
5. Replace the fuse with a new one of the same rating.
6. Reinstall in the reverse order of removal.
