If your temperature gauge indicates
overheating, you experience a loss of
power, or hear loud pinging or knocking,
the engine may be overheating. If this
happens, you should:
1. Pull off the road and stop as soon as it is safe to do so.
2. Place the shift button in P (Park) and set the parking brake
3. Make sure that there is no hot steam gushing out of the engine
compartment. When it is safe to do
so, open the engine compartment,
and check the water-pump connector.
When the water-pump connector is
disconnected, stop the engine, re-
connect the water-pump connector,
and then re-start the engine.
4. Set the temperature and the air flow to the maximum, and turn ON the air
conditioner.
WARNING
While the engine is running,
keep hands, clothing and tools
away from the moving parts
such as the cooling fan and
drive belt to prevent serious
injury. 5. When the Service warning light (
)
illuminates on the instrument cluster,
immediately stop the engine, and
we recommend that you contact an
authorized HYUNDAI dealer. When the
engine warning light (
) illuminates,
or when the coolant or hot steams
gush out of the engine compartment,
leave the engine compartment
opened, while running the engine.
This is to ventilate the engine
compartment and to cool down the
engine.
6. Check the coolant temperature gauge on the instrument cluster to
make sure the coolant temperature is
sufficiently cooled down. Check the
coolant level. When it is insufficient,
check its connection with the radiator,
the heater hose, and the water pump
for any leakage. When there is no
leakage, add the coolant. However,
if the problems persists, such as
the illumination of the warning
lights, leakages, or the cooling-fan
malfunction, which may overheat the
engine, immediately stop the engine,
and we recommend that the vehicle
checked by an authorized HYUNDAI
dealer.

Maintenance9-6
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 looseness in the
steering 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 transmission occurs,
check the transmission fluid level.

[ Check the automatic transmission 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 flashers.

[ 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.
At least twice a year: (i.e., every
Spring and Autumn)

[Check radiator, heater and air
conditioning hoses for leaks or
damage.

[ Check windshield washer spray and
wiper operation. Clean wiper blades
with a clean cloth dampened with
washer fluid.

[ Check headlamp alignment.

[ Check muffler, exhaust pipes, shields
and clamps.

[ Check the seat belts for wear and
function.
At least once a year:

[Clean body and door drain holes.

[ Lubricate door hinges and hood
hinges.

[ Lubricate door and hood locks and
latches.

[ Lubricate door rubber weather strips.

[ Check the air conditioning system.

[ Inspect and lubricate automatic
transmission linkage and controls.

[ Clean the battery and terminals.

[ Check the brake fluid level.

Checking the Engine Oil and
Filter

[The lubrication, rust prevention,
cooling, and cleaning effect of the
engine oil will gradually degrade
during its use. Have the engine oil and
filter be changed by an authorized
HYUNDAI dealer according to the
Oil Life Management System or
the Maintenance Schedule at the
beginning of this chapter.

[ If the maintenance schedule to
replace engine oil is exceeded,
the engine oil performance may
deteriorate, and the engine condition
may be affected. Therefore, replace
the engine oil according to the
maintenance schedule.

[ To keep the engine in optimal
condition, use the recommended
engine oil and filter. If the
recommended engine oil and filter are
not used, replace it according to the
maintenance schedule under severe
usage conditions.

[ The purpose of the maintenance
schedule for engine oil replacement
is to prevent oil deterioration and it is
irrelevant to oil consumption. Check
and refill engine oil regularly.
Information
When the oil pressure is low due to
insufficient engine oil, the Engine
Oil Pressure (
) warning light will
illuminate. In addition, the enhanced
engine protection system, which limits
the engine’s power is activated and the
Malfunction Indicator Lamp (
) will
illuminate when the vehicle is driven in
this state continuously. When oil pressure
is restored, the Engine Oil Pressure
warning light will turn off and the engine
power will no longer be limited.
CAUTION
The engine oil is very hot immediately
after the vehicle has been driven and
can cause burns during replacement.
Replace the engine oil after the engine
oil has cooled down.
WARNING
CALIFORNIA PROPOSITION 65
WARNING
Engine oil contains chemicals known to
the State of California to cause cancer,
birth defects and reproductive harm.
Used engine oil may cause irritation or
cancer of the skin if left in contact with
the skin for prolonged periods of time.
Always protect your skin by washing
your hands thoroughly with soap and
warm water as soon as possible after
handling used oil.

Battery Recharging
By battery charger
Your vehicle has a maintenance-free,
calcium-based battery.

[If the battery becomes discharged
over a short time (because, for
example, the headlamps 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 electrical load while
the vehicle is being used, recharge it
at 20-30A for two hours.
WARNING
Always follow these instructions when
recharging your vehicle’s battery to
avoid the risk of SERIOUS INJURY or
DEATH from explosions or acid burns:

[Before performing maintenance or
recharging the battery, turn off all
accessories and stop the engine.

[ 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.

[ Watch the battery during charging,
and stop or reduce the charging
rate if the battery cells begin boiling
violently.

Normal Blown
Normal Blown
OTM078035
A vehicle’s electrical system is protected
from electrical overload damage by
fuses.
This vehicle has 2 (or 3) fuse panels, one
located in the driver’s side panel bolster,
the other in the engine compartment.
If any of your vehicle’s lights,
accessories, 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 rating.
If the replacement fuse blows, this
indicates an electrical problem.
Avoid using the system involved. We
recommend that you immediately
consult an authorized HYUNDAI dealer.
Information
Three kinds of fuses are used: blade type
for lower amperage rating, cartridge
type, and multi fuse for higher amperage
ratings.
FUSES

09
9-43
WARNING
NEVER replace a fuse with anything 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 aluminum
foil instead of the proper fuse -
even as a temporary repair. It may
cause extensive wiring damage and
possibly a fire.
NOTICE
Do not use a screwdriver or any other
metal object to remove fuses because
it may cause a short circuit and damage
the system.

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 of
the fuse panel cover to locate the
suspected fuse location.
OTMH090014
5. Pull the suspected fuse straight out. Use the removal tool provided in the
engine compartment fuses panel
cover.
6. Check the removed fuse; replace it if it is blown. Spare fuses are provided in
the instrument panel fuse panels (or in
the engine compartment 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, we recommend
that you 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 undamaged, check the fuse panel
in the engine compartment. If a fuse is
blown, it must be replaced with the same
rating.
