OWNER MAINTENANCE
WARNING
Performing maintenance work on a
vehicle can be dangerous. If you lack
sufficient knowledge and experience
or the proper tools and equipment to
do the work, we recommend that the
system be serviced by an authorized
HYUNDAI dealer. ALWAYS follow
these precautions for performing
maintenance work: • Park your vehicle on level ground,
shift to P (Park) position, apply the
parking brake, place the START/STOP
button in the OFF position.
• Block the tires (front and back) to
prevent the vehicle from moving.
Remove loose clothing or jewelry
that can become entangled in
moving parts.
• Keep flames, sparks, or smoking
materials away from the battery and
motor related parts.
The following lists are vehicle checks and
inspections that should be performed
by the owner or an authorized HYUNDAI
dealer at the frequencies indicated to
help ensure safe, dependable operation
of your vehicle.
Any adverse conditions should be
brought to the attention of your dealer as soon as possible.
These Owner Maintenance vehicle
checks are generally not covered by
warranties and you may be charged for
labor, parts and lubricants used.Owner maintenance schedule
When you stop for charging: • Check the coolant level in the coolant
reservoir.
• Check the windshield washer fluid
level.
• Check for low or under-inflated tires.
WARNING
Be careful when checking your coolant
level when the motor compartment is
hot. This may result in coolant being
blown out of the opening and cause
serious burns and other injuries.

Maintenance
9-6
While operating your 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 reduction gear
occurs, check the reduction gear fluid
level.
• Check the reduction gear 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 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.
• Do not add regular green coolant. •
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 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 reduction gear
linkage and controls.
• Clean the battery and terminals.
• Check the brake fluid level.

BATTERY (12 VOLT)
WARNING
To prevent SERIOUS INJURY or DEATH
to you or bystanders, always follow
these precautions when working near
or handling the battery:
Always read and follow
instructions carefully when
handling a battery.
Wear eye protection designed
to protect the eyes from acid splashes.
Keep all flames, sparks, or
smoking materials away from
the battery.
Hydrogen is always present
in battery cells, is highly
combustible, and may explode
if ignited.
Keep batteries out of reach of
children.
Batteries contain sulfuric acid
which is highly corrosive. Do
not allow acid to contact your
eyes, skin or clothing.
If acid gets into your eyes, flush your
eyes with clean water for at least 15
minutes and get immediate medical
attention. If acid gets on your skin,
thoroughly wash the area. If you feel
pain or a burning sensation, get medical
attention immediately.
• When lifting a plastic-cased battery,
excessive pressure on the case may
cause battery acid to leak. Lift with a
battery carrier or with your hands on
opposite corners.
• Do not attempt to jump start your
vehicle if your battery is frozen.
• NEVER attempt to recharge the
battery when the vehicle’s battery
cables are connected to the battery.
• The electrical ignition switch works
with high voltage. NEVER touch
these components with the “
”
indicator ON or when the START/
STOP button is in the ON position.
NOTICE
• When you do not use the vehicle for a
long time in a low temperature area,
disconnect the battery and keep it
indoors.
• Always charge the battery fully to
prevent battery case damage in low
temperature areas.
NOTICE
If you connect unauthorized electronic
devices to the battery, the battery may
be discharged. Never use unauthorized
devices.

Battery recharging
By battery charger
Your vehicle has a maintenance-free,
calcium-based battery. • If the battery becomes discharged in a
short 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.
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 place the START/
STOP button to the OFF position.
• Keep all flames, sparks, or smoking
materials away from the battery.
• Always work outdoors or in an area
with plenty of ventilation.
