OWNER MAINTENANCE
The following lists are vehicle checks
and inspections that should be per-
formed by the owner or an author-
ized HYUNDAI dealer at the frequen-
cies indicated to help ensure safe,
dependable operation of your vehi-
cle.
Any adverse conditions should be
brought to the attention of your deal-
er as soon as possible.
These Owner Maintenance Checks
are generally not covered by war-
ranties and you may be charged for
labor, parts and lubricants used.Owner maintenance schedule
When you stop for fuel:
• Check the engine oil level.
Check coolant level in coolantreservoir.
Check the windshield washer fluid level.
Look for low or under-inflated tires.
While operating your vehicle:
Note any changes in the sound of the exhaust or any smell of
exhaust fumes in the vehicle.
Check for vibrations in the steering wheel. Notice any increased steer-
ing effort or looseness in the steer-
ing wheel, or change in its straight-
ahead position.
Notice if your vehicle constantly turns slightly or "pulls" to one side
when traveling on smooth, level
road.
When stopping, listen and check for unusual sounds, pulling to one
side, increased brake pedal travel
or "hard-to-push" brake pedal.
If any slipping or changes in the operation of your transaxle occurs,
check the transaxle fluid level.
Check automatic transaxle P (Park) function.
Check parking brake.
Check for fluid leaks under your vehicle (water dripping from the air
conditioning system during or after
use is normal).
WARNING
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot
coolant and steam may blow
out under pressure. This could
cause burns or other serious
injury.

Battery recharging
Your vehicle has a maintenance-free,
calcium-based battery.
If the battery becomes discharged
in 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.(Continued)
When lifting a plastic-casedbattery, 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.CALIFORNIA PROPO-
SITION 65 WARNING
Battery posts, terminals, and
related accessories contain
lead and lead compounds,
chemicals known to the State of
California to cause cancer, birth
defects, and reproductive harm.
Batteries also contain other
chemicals known to the State of
California to cause cancer.
Wash hands after handling.
CAUTION
Always charge the battery fully to prevent battery casedamage in low temperaturearea.
If you connect unauthorized electronic devices to the bat-tery, the battery may dis-charge. Never use unautho-rized devices.

Maintenance
Compact spare tire replacement
A compact spare tire has a shorter
tread life than a regular size tire.
Replace it when you can see the
tread wear indicator bars on the tire.
The replacement compact spare tire
should be the same size and design
tire as the one provided with your
new vehicle and should be mounted
on the same compact spare tire
wheel. The compact spare tire is not
designed to be mounted on a regular
size wheel, and the compact spare
tire wheel is not designed for mount-
ing a regular size tire.
Wheel replacement
When replacing the metal wheels for
any reason, make sure the new
wheels are equivalent to the original
factory units in diameter, rim width
and offset.
Tire traction
Tire traction can be reduced if you
drive on worn tires, tires that are
improperly inflated or on slippery
road surfaces. Tires should be
replaced when tread wear indicators
appear. To reduce the possibility of
losing control, slow down whenever
there is rain, snow or ice on the road.
WARNING
A wheel that is not the correct
size may adversely affect wheel
and bearing life, braking and
stopping abilities, handling
characteristics, ground clear-
ance, body-to-tire clearance,
snow chain clearance,
speedometer and odometer cal-
ibration, headlight aim and
bumper height.

FUSES
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.
Always replace a blown fuse with
one of the same rating.
Before replacing an open fuse, dis-
connect the negative battery cable.
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 multi fuse for higheramperage ratings.✽ ✽ NOTICE
The actual fuse/relay panel label
may differ from equipped items.

WARNING - 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 alu- minum foil instead of the
proper fuse - even as a tem-
porary repair. It may cause
extensive wiring damage and
a possible fire.
CAUTION
Do not use a screwdriver or anyother metal object to removefuses because it may cause ashort circuit and damage thesystem.■ Battery fuse terminal

LIGHT BULBS
Use only the bulbs of the specified
wattage.
✽
✽ NOTICE
After heavy, driving rain or wash-
ing, headlamp and taillamp lenses
could appear frosty. This condition
is caused by the temperature differ-
ence between the lamp inside and
outside. This is similar to the con-
densation on your windows inside
your vehicle during the rain and
doesn't indicate a problem with
your vehicle. If the water leaks into
the lamp bulb circuitry, have the
vehicle checked by an authorized
HYUNDAI dealer.WARNING - Working on
the lights
Prior to working on the light,
firmly apply the parking brake,
ensure that the ignition switch
is turned to the "LOCK" posi-
tion and turn off the lights to
avoid sudden movement of the
vehicle and burning your fin-
gers or receiving an electric
shock.
CAUTION
Be sure to replace the burned-
out bulb with one of the samewattage rating. Otherwise, itmay cause damage to the fuseor electric wiring system.
CAUTION
If you don't have necessarytools, the correct bulbs and theexpertise, consult an authorizedHYUNDAI dealer. In many cases,it is difficult to replace vehiclelight bulbs because other partsof the vehicle must be removedbefore you can get to the bulb.This is especially true if youhave to remove the headlightassembly to get to the bulb(s).Removing/installing the head-light assembly can result indamage to the vehicle.
