IF THE ENGINE WILL NOT START
If the engine doesn't turn over
or turns over slowly
• Be sure the shift lever is in N
(Neutral) or P (Park) if it is an auto-
matic transaxle vehicle. The engine
starts only when the shift lever is in
N (Neutral) or P (Park).
• Check the battery connections to
be sure they are clean and tight.
• Turn on the interior light. If the light
dims or goes out when you operate
the starter, the battery is drained.
Do not push or pull the vehicle to
start it. This could cause damage to
your vehicle. See instructions for
"Jump Starting" provided in this
chapter.
If the engine turns over nor-
mally but doesn’t start
• Check the fuel level and add fuel if
necessary.
If the engine still does not start, call
an authorized HYUNDAI dealer for
assistance.

Maintenance
Owner maintenance schedule
When you stop for fuel:
• Check the engine oil level.
• Check coolant level in the engine
coolant reservoir.
• Check the windshield washer fluid
level.
• Check 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 if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead posi-
tion.
• 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 the automatic transaxle P
(Park) function.
• Check the parking brake.
• Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
• Check coolant level in the engine
coolant reservoir.
• Check the operation of all exterior
lights, including the stoplights, turn
signals and hazard warning flash-
ers.
• Check the inflation pressures of all
tires including the spare for tires
that are worn, show uneven wear,
or are damaged.
• Check for loose wheel lug nuts.
WARNING
Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of the
opening and cause serious
burns and other injuries.

FUSES
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 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 or broken.
If the electrical system does not
work, first check the driver’s side
fuse panel. Before replacing a blown
fuse, disconnect 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.✽NOTICE
Three kinds of fuses are used: blade
type for lower amperage rating, car-
tridge type, and multi fuse for high-
er amperage ratings.

WARNING
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.

LIGHT BULBS
Consult an authorized HYUNDAI
dealer to replace most vehicle light
bulbs. It is difficult to replace vehicle
light bulbs because other parts of the
vehicle must be removed before you
can get to the bulb. This is especially
true for removing the headlight
assembly to get to the bulb(s).
Removing/installing the headlight
assembly can result in damage to
the vehicle.
✽NOTICE
After heavy driving, rain or wash-
ing, headlight and taillight lenses
could appear frosty. This condition
is caused by the temperature differ-
ence between the lamp inside and
the outside temperature. This is sim-
ilar to the condensation on your win-
dows 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
your vehicle checked by an author-
ized HYUNDAI dealer.
Headlight, parking light, turn
signal light, side marker and
front fog light bulb replace-
ment WARNING
• Prior to replacing a light,
depress the foot brake, move
the shift lever into P (Park)
apply the parking brake, place
the ignition switch in the
LOCK/OFF position, and take
the key with you when leaving
the vehicle to avoid sudden
movement of the vehicle and
to prevent possible electric
shock.
• Be aware the bulbs may be
hot and may burn your fin-
gers.

* : if equippedHalogen bulb• Always handle them carefully, and
avoid scratches and abrasions. If
the bulbs are lit, avoid contact with
liquids.
• Never touch the glass with bare
hands. Residual oil may cause the
bulb to overheat and burst when lit.
• A bulb should be operated only
when installed in a headlamp.
• If a bulb becomes damaged or
cracked, replace it immediately
and carefully dispose of it.
OMD070053N
WARNING
• Handle halogen bulbs with
care. Halogen bulbs contain
pressurized gas that will pro-
duce flying pieces of glass
that could cause injuries if
broken.
• Wear eye protection when
changing a bulb. Allow the
bulb to cool down before han-
dling it.

APPEARANCE CARE
Exterior care
Exterior general caution
It is very important to follow the label
directions when using any chemical
cleaner or polish. Read all warning
and caution statements that appear
on the label.
Finish maintenance
Washing
To help protect your vehicle’s finish
from rust and deterioration, wash it
thoroughly and frequently at least
once a month with lukewarm or cold
water.
If you use your vehicle for off-road
driving, you should wash it after each
off-road trip. Pay special attention to
the removal of any accumulation of
salt, dirt, mud, and other foreign
materials. Make sure the drain holes
in the lower edges of the doors and
rocker panels are kept clear and
clean.Insects, tar, tree sap, bird droppings,
industrial pollution and similar
deposits can damage your vehicle’s
finish if not removed immediately.
Even prompt washing with plain
water may not completely remove all
these deposits. A mild soap, safe for
use on painted surfaces, should be
used.
After washing, rinse the vehicle thor-
oughly with lukewarm or cold water.
Do not allow soap to dry on the fin-
ish.
WARNING
After washing the vehicle, test
the brakes while driving slowly
to see if they have been affected
by water before getting on the
road. If braking performance is
impaired, dry the brakes by
applying them lightly while
maintaining a slow forward
speed.
CAUTION
• Do not use strong soap, chem-
ical detergents or hot water,
and do not wash the vehicle in
direct sunlight or when the
body of the vehicle is warm.
• Be careful when washing the
side windows of your vehicle.
Especially, with high-pressure
water. Water may leak through
the windows and wet the inte-
rior.
• To prevent damage to the
plastic parts, do not clean with
chemical solvents or strong
detergents.

Aluminum wheel maintenance
The aluminum wheels are coated
with a clear protective finish.
Corrosion protection
Protecting your vehicle from corro-
sion
By using the most advanced design
and construction practices to combat
corrosion, HYUNDAI produces cars
of the highest quality. However, this is
only part of the job. To achieve the
long-term corrosion resistance your
vehicle can deliver, the owner's
cooperation and assistance is also
required.
Common causes of corrosion
The most common causes of corro-
sion on your vehicle are:
• Road salt, dirt and moisture that is
allowed to accumulate underneath
the vehicle.
• Removal of paint or protective
coatings by stones, gravel, abra-
sion or minor scrapes and dents
which leave unprotected metal
exposed to corrosion.WARNING
After washing the vehicle, test
the brakes while driving slowly
to see if they have been affected
by water. If braking performance
is impaired, dry the brakes by
applying them lightly while
maintaining a slow forward
speed.
CAUTION
• Do not use abrasive cleaner,
polishing compound, solvent,
or wire brushes on aluminum
wheels.
• Clean the wheel when it has
cooled.
• Use only a mild soap or neu-
tral detergent, and rinse thor-
oughly with water. Also, clean
the wheels after driving on
salted roads.
• Do not wash the wheels with
high-speed car wash brushes.
• Do not use any cleaners con-
taining acid or alkaline deter-
gents.
