Maintenance
For mixture percentage, refer to the
following table.Changing the coolant
Have coolant changed by an author-
ized HYUNDAI dealer according to
the Maintenance Schedule at the
beginning of 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
pressure causing serious
injury.
CAUTION
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.
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 AND CLUTCH (IF EQUIPPED) FLUID
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
accumulated mileage. This is a nor-
mal condition associated with the
wear of the brake linings. If the fluid
level is excessively low, have the
brake system checked by an author-
ized HYUNDAI dealer.
Use only the specified brake/clutch
fluid. (Refer to “Recommended lubri-
cants or capacities” in section 8.)
Never mix different types of fluid.
WARNING - Brake fluid
When changing and adding
brake/clutch fluid, handle it
carefully. Do not let it come in
contact with your eyes. If
brake/clutch fluid should come
in contact with your eyes, imme-
diately flush them with a large
quantity of fresh tap water. Have
your eyes examined by a doctor
as soon as possible.
WARNING - Loss of
brake fluid
In the event the brake system
requires frequent additions of
fluid, the vehicle should be
inspected by an authorized
HYUNDAI dealer.
OBK079007
CAUTION
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 can-
not be guaranteed. It should 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 your brake /
clutch system can damage
brake / clutch system parts.

Maintenance
POWER STEERING FLUID
Checking the power steering
fluid level
With the vehicle on level ground,
check the fluid level in the power
steering reservoir periodically. The
fluid should be between MAX and
MIN marks on the side of the gauge
at the normal temperature.
Before adding power steering fluid,
thoroughly clean the area around the
reservoir cap to prevent power steer-
ing fluid contamination.
If the level is low, add fluid to the
MAX level.
✽ ✽
NOTICE
Check that the fluid level is in the
"HOT" range on the gauge. If the
fluid is cold, check that it is in the
"COLD" range.
In the event the power steering sys-
tem requires frequent addition of
fluid, the vehicle should be inspected
by an authorized HYUNDAI dealer.
Use only the specified power steering
fluid. (Refer to "Recommended lubri-
cants or capacities" in section 8.)
Checking the power steering
hose
Check the connections for oil leaks,
damage and twists in the power
steering hose before driving.
CAUTION
To avoid damage to the power
steering pump, do not operate
the vehicle for prolonged peri-
ods with a low power steering
fluid level.
Never start the engine when
the reservoir tank is empty.
When adding fluid, be careful
that dirt does not get into the
tank.
Too little fluid can result in
increased steering effort
and/or noise from the power
steering system.
(Continued)
(Continued)
The use of the non-specified
fluid could reduce the effective-
ness of the power steering sys-
tem and cause damage to it.

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 should be inspected
more frequently and replaced earlier.
When you replace the climate control
air filter, replace it performing the fol-
lowing procedure, and be careful to
avoid damaging other components.
Filter replacement
1. Open the glove box and remove
the support rod (1).
CAUTION
Do not drive with the air clean-
er 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.
Use a HYUNDAI genuine part.
Use of non-genuine parts
could damage the air flow sen-
sor.

Maintenance
Battery recharging
Your vehicle has a maintenance-free,
calcium-based battery.
If the battery becomes discharged
try jump starting the battery from
another vehicle's battery according
to the instructions of section 6-4. Be
sure to run vehicle for at least 15
minutes to charge the battery
enough to be able to restart the vehi-
cle after it is shut off.(Continued)
When lifting a plastic-cased
battery, excessive pressure
on the case may cause battery
acid to leak, resulting in per-
sonal injury. Lift with a battery
carrier or with your hands on
opposite corners.
Never attempt to recharge the
battery when the battery
cables are connected.
The electrical ignition system
works with high voltage.
Never touch these compo-
nents with the engine running
or the ignition switched on.
Failure to follow the above
warnings can result in serious
bodily injury or death.
CAUTION
When you don’t use the vehi-
cle for a long time in low tem-
perature weather, separate the
battery and keep it indoors.
Always charge the battery fully
to prevent battery case damage
in low temperature weather.
If you connect unauthorized
electronic devices to the bat-
tery, the battery may be dis-
charged. Never use unautho-
rized devices.
CALIFORNIA PROPOSI-
TION 65 WARNING

related accessories contain
lead and lead compounds,
chemicals known to the State of
California to cause cancer, birth

FUSES
A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.This vehicle has 3 fuse panels, one
located in the driver’s side panel bol-
ster, the others 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.
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
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, car-
tridge type, and fusible link for higher
amperage ratings.

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 or alu-
minum foil instead of the prop-
er 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 circuit and damage the
system.

Instrument panel fuse replace-
ment
1. Turn the ignition switch and all
other switches off.
2. Open the fuse panel cover.
3. Pull the suspected fuse straight
out. Use the removal tool provided
in the main fuse box in the engine
compartment.
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, consult an authorized
HYUNDAI dealer.
If you do not have a spare, 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 headlights 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.
OBK079019
CAUTION
When replacing a blown fuse
or relay with a new one, make
sure the new fuse or relay fits
tightly into the clips. The
incomplete fastening fuse or
relay may cause the vehicle
wiring and electric systems
damage and a possible fire.
Do not remove fuses, relays
and terminals fastened with
bolts or nuts. The fuses, relays
and terminals may be fas-
tened incompletely, and it may
cause a possible fire. If fuses,
relays and terminals fastened
with bolts or nuts are blown,
consult with an authorized
HYUNDAI dealer.
Do not input any other objects
except fuses or relays into
fuse/relay terminals such as a
driver or wiring. It may cause
contact failure and system
malfunction.
