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.

EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
Cooling system
Check the cooling system parts, such
as radiator, coolant reservoir, hoses and
connections for leakage and damage.
Replace any damaged parts.
Coolant
The coolant should be changed at the
intervals specified in the maintenance schedule.
Reduction gear fluid
The reduction gear fluid should be
inspected according to the intervals
specified in the maintenance schedule.
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and any
leakage. Replace any deteriorated or
damaged parts immediately.
Brake fluid
Check the brake fluid level in the brake
fluid reservoir. The level should be
between “MIN” and “MAX” marks on the
side of the reservoir. Use only hydraulic
brake fluid conforming to DOT 3 or DOT 4
specification.
Brake pads, calipers and rotors
Check the pads for excessive wear, discs
for run out and wear, and calipers for
fluid leakage.
For more information on checking the
pads or lining wear limit, refer to the
HYUNDAI web site.
(http://service.hyundai-motor.com)
Suspension mounting bolts
Check the suspension connections for
looseness or damage. Retighten to the
specified torque.
Steering gear box, linkage &
boots/lower arm ball joint
With the vehicle stopped, check for
excessive free-play in the steering wheel.
Check the linkage for bends or damage.
Check the dust boots and ball joints
for deterioration, cracks, or damage.
Replace any damaged parts.
Drive shafts and boots
Check the drive shafts, boots and clamps
for cracks, deterioration, or damage.
Replace any damaged parts and, if
necessary, repack the grease.
Air conditioning refrigerant/
compressor
Check the air conditioning lines and
connections for leakage and damage.

Maintenance
9-10
COOLANT
OOSEV078002
Check the condition and connections
of all cooling system hoses and
heater hoses. Replace any swollen or
deteriorated hoses.
The coolant level should be filled
between the MAX and the MIN marks on
the side of the coolant reservoir when
the parts in the motor compartment is cool.
If the coolant is low, we recommend
to have the vehicle inspected by an
authorized HYUNDAI dealer.
Use only designated coolant water for
electric vehicles, adding other types
of water or antifreeze can damage the
vehicle.
WARNING
Since specific coolant water (Blue color,
Low conductivity) is applied for electric
vehicles, replenishment of other
antifreeze or water may cause problems
to the vehicle.
WARNING
The electric motor for the
cooling fan may continue to
operate or start up when
the vehicle is not running and can cause serious
injury.
Keep hands, clothing and
tools away from the rotating
fan blades of the cooling fan.
The electric motor for the cooling
fan is controlled by vehicle coolant
temperature, refrigerant pressure and
vehicle speed. As the vehicle coolant
temperature decreases, the electric
motor will automatically shut off. This is a normal condition.

9-11
BRAKE FLUID
Checking the brake fluid level
OOSEV078003
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 fluid, clean the area around
the reservoir cap thoroughly to prevent
brake fluid contamination.
If the level is low, add fluid to the MAX
level. The level will fall with accumulated mileage. This is a normal condition
associated with the wear of the brake linings.
If the fluid level is excessively low, we
recommend that the system be checked
by an authorized HYUNDAI dealer.
Information
• Use only the specified brake fluid.
Refer to “Recommended lubricants and
capacities” in chapter 2.
• Before removing the brake filler cap,
read the warning on the cap.
• Clean the filler cap before removing.
Use only DOT3 or DOT4 brake fluid
from a sealed container.
WARNING
If the brake system requires frequent
additions of fluid this could indicate
a leak in the brake system. We
recommend that the vehicle be
inspected by an authorized HYUNDAI
dealer.
WARNING
Do not allow brake fluid to come in
contact with your eyes. If brake fluid
comes in contact with your eyes, flush
your eyes with clean water for at least
15 minutes and get immediate medical
attention.
NOTICE
• Do not allow brake fluid to contact
the vehicle’s body paint, as paint
damage will result.
• Brake fluid, which has been exposed
to open air for an extended time
should never be used as its quality
cannot be guaranteed. It should be
disposed of properly.
• Don’t put in the wrong kind of fluid.
A few drops of mineral-based oil,
in your brake system can damage
system parts.

Maintenance
9-12
WASHER FLUID
Checking the washer fluid level
OOSEV078004
Check the fluid level in the washer fluid
reservoir and add fluid if necessary. plain
water may be used if washer fluid is not
available. However, use washer solvent
with antifreeze characteristics in cold
climates to prevent freezing.
WARNING
To prevent serious injury or death, take
the following safety precautions when
using washer fluid: • Do not use coolant or antifreeze in
the washer fluid reservoir. Coolant
can severely obscure visibility when
sprayed on the windshield and
may cause loss of vehicle control
resulting in an accident or damage to
paint and body trim.
• Do not allow sparks or flames to
contact the washer fluid or the
washer fluid reservoir. Washer fluid
may contain alcohol and can be flammable.
• Do not drink washer fluid and avoid
contact with skin. Washer fluid is
poisonous to humans and animals.
• Keep washer fluid away from
children and animals.
