Maintenance
Check the condition and connections of all cooling system hoses and heater
hoses. Replace any swollen or deterio-
rated hoses.
The coolant level should be filled
between F and L marks on the side of the
coolant reservoir when the engine iscool.
If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the
level to F, but do not overfill. If frequent
additions are required, see an authorized
HYUNDAI dealer for a cooling systeminspection.
Recommended engine coolant
When adding coolant, use only deion-ized water or soft water for your vehicle
and never mix hard water in the
coolant filled at the factory. An improp-
er coolant mixture can result in serious
malfunction or engine damage.
The engine in your vehicle has alu- minum engine parts and must be pro-
tected by an ethylene-glycol-based
coolant to prevent corrosion and freez-ing.
DO NOT USE alcohol or methanol coolant or mix them with the specifiedcoolant.
Do not use a solution that contains more than 60% antifreeze or less than
35% antifreeze, which would reduce
the effectiveness of the solution.

(Continued)
Turn the engine off and wait untilit 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 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 operat- ing, do not remove the radiator cap or the drain plug while the
engine and radiator are hot. Hot
coolant and steam may still blow
out under pressure, causing seri-
ous injury.

For mixture percentage, refer to the fol-
lowing table.Changing the coolant
Have coolant changed by an authorized
HYUNDAI dealer according to theMaintenance Schedule at the beginningof this section.
WARNING - Radiator cap
Do not remove the radiator cap when the engine and radiator are
hot. Scalding hot coolant and
steam may blow out under pres-
sure causing serious injury.
OLM079007
CAUTION
Put a thick cloth around the radiator
cap before refilling the coolant inorder to prevent the coolant from
overflowing into engine parts suchas the generator.
WARNING -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.

BRAKE/CLUTCH (IF EQUIPPED) FLUID
Checking the brake/clutch* fluid
level
Check the fluid level in the reservoir peri-
odically. 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 contamina-tion. *
:if equippedIf the level is low, add fluid to the MAX
level. The level will fall with accumulated
mileage. This is a normal condition asso-
ciated with the wear of the brake linings
and/or clutch disc (if equipped). If the
fluid level is excessively low, have the
brake/clutch* system checked by an
authorized HYUNDAI dealer.
Use only the specified brake/clutch* fluid.
(Refer to “Recommended lubricants andcapacities” in section 8.)
Never mix different types of fluid.
WARNING - Brake/clutch* fluid
When changing and adding
brake/clutch* fluid, handle it care-
fully. Do not let it come in contact
with your eyes. If brake/clutch* fluid
should come in contact with your
eyes, immediately flush them with a
large quantity of fresh tap water.
Have your eyes examined by a doc-
tor as soon as possible.
WARNING - Loss of
brake/clutch* fluid
In the event the brake/clutch* system
requires frequent additions of fluid,
the vehicle should be inspected by
an authorized HYUNDAI dealer.
OLM079008N
CAUTION
Do not allow brake/clutch* fluid to contact the vehicle's body paint, aspaint damage will result.
Brake/clutch* fluid, which has beenexposed to open air for an extended time should never be used as itsquality cannot be guaranteed. Itshould 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 yourbrake/clutch* system can damage
brake/clutch* system parts.

Maintenance
Filter inspection
The climate control air filter should be replaced according to the Maintenance
Schedule. If the vehicle is operated in
severely air-polluted cities or on dusty
rough roads for a long period, it shouldbe inspected more frequently and
replaced earlier. When you replace the
climate control air filter, replace it per-
forming the following procedure, and be
careful to avoid damaging other compo-
nents.
Filter replacement
1. Open the glove box and remove thesupport rod (1).
CAUTION
Do not drive with the air cleaner
removed; this will result in exces-sive engine wear.
When removing the air cleaner fil- ter, be careful that dust or dirtdoes not enter the air intake, ordamage may result.
Use a HYUNDAI genuine part. Use of non-genuine parts could dam-age the air flow sensor.

Maintenance
Battery recharging
Your vehicle has a maintenance-free,
calcium-based battery.
If the battery becomes discharged in ashort time (because, for example, 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.(Continued)
When lifting a plastic-cased bat-tery, excessive pressure on the
case may cause battery acid to
leak, resulting in personal injury.
Lift with a battery carrier or with
your hands on opposite corners.
Never attempt to recharge the battery when the battery cablesare connected.
The electrical ignition system works with high voltage. Never
touch these components with the engine running or the ignition
switched on.
Failure to follow the above warn-
ings can result in serious bodily
injury or death.
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 charg-
ing rate if the battery cells begin
gassing (boiling) violently or if
the temperature of the electrolyte
of any cell exceeds 120°F (49°C).

FUSES
A vehicle’s electrical system is protected
from electrical overload damage by
fuses.
This vehicle has 3 fuse panels, one locat-
ed in the driver’s side panel bolster, the
other in the engine compartment.
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 willmelt.
If the electrical system does not work,
first check the driver’s side fuse panel.
Always replace a blown fuse with one of
the same rating.
If the replacement fuse blows, this indi-
cates an electrical problem. Avoid using
the system involved and immediately
consult an authorized HYUNDAI dealer.
Four kinds of fuse are used: blade type,cartridge type, multi fuse and main fuse.
WARNING - Fuse replace-
ment
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 instead of the proper fuse - even as a temporary
repair. It may cause extensive
wiring damage and a possible fire.
CAUTION
Do not use a screwdriver or any
other metal object to remove fuses
because it may cause a short circuitand damage the system.

Maintenance
Instrument panel fuse replace- ment
1. Turn the ignition switch and all otherswitches off.
2. Open the fuse panel cover. 3. Pull the suspected fuse straight out.
Use the removal tool provided in the fuse panel.
4. Check the removed fuse; replace it if it is blown.
Spare fuses are provided in the instru-
ment panel fuse panel (or in the enginecompartment 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.
If you do not have a spare, use a fuse of the same rating from a circuit you maynot need for operating the vehicle, such as the cigarette lighter fuse.
If the headlights or other electrical com-
ponents do not work and the fuses are
OK, check the fuse panel in the engine
compartment. If a fuse is blown, it mustbe replaced.
